Cloud computing is one of the newest service innovations in the IT sector. One of the technologies that is predicted to grow the fastest in the coming years is cloud computing. The term “cloud computing” first surfaced, during a joint project between Google and IBM in the fourth quarter of 2007 ( Vouk, 2008 ; Zhang et al., 2010 ). In actuality, cloud computing is not a new idea; it was first used by businesses to manage virtual data resources in the 1960s. But it wasn’t until the early 21st century that it became widely known, as evidenced by the introduction of Microsoft’s Azure in 2010, Google’s App Engine in 2008, and Amazon Web Services in 2006. These three cloud service providers currently hold a 65% market share. However, there are additional ones. Sales force, IBM Cloud, Alibaba Cloud, and other clouds add even more variety to the already diverse cloud landscape. As per the National Institute of Standards and Technology (NIST), cloud computing, is “a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” ( Mell & Grance, 2011 ).

The main benefit of cloud computing is that it can be accessed from anywhere at any time, regardless of schedule constraints. Financial institutions can benefit from cost savings, usage-based billing, business continuity, business agility, and green IT, among other benefits. According to Nazoksara et al. (2024) , cloud computing provides cost savings, flexibility in handling storage capacities, and support for interactive and portable apps and services. Additionally, cloud computing solutions allow users to choose from a variety of providers based on their needs because they are multi-source ( Kumar et al., 2022 ; Panwar et al., 2022 ). Furthermore, cloud computing reduces the need for physical space and operations for on-site storage, as well as capital costs and power consumption. Furthermore, cloud computing is “open to every service,” but it only handles the data that is absolutely necessary. Users can access cloud services to enable effective computation ( Chang et al., 2022 ; Sharon et al., 2022 ). Moving to the cloud is justified for a number of reasons, including reduced time to market, lower cost of ownership, and more flexible infrastructure. As cloud computing adoption increases, financial institutions must consider the advantages and disadvantages of each option before making a choice. Adopt cloud computing and implement the proper oversight and governance to realize business benefits successfully and at a risk that is manageable Sumathy and Anitha Rathna (2018) . Users can access IT services through cloud computing without having to understand the technology or own the infrastructure ( Singh, 2012 ). By offering different entry points, cloud computing technology is significantly contributing to the simplification, cost reduction, and ease of transactions for all clients. Indian banks should all quickly implement cloud computing services for everyone. Without a doubt, it will give our banking industries a lively break and contribute to our economic expansion ( Kamesh & Linda, 2018 ).

The biggest market for cloud services spending will be in business applications, where there will be a gradual shift from on-premise to cloud-based services, particularly for common business applications like ERP and CRM (Customer Relationship Management). In their study, Ghane et al. (2016) assess how cloud computing affects the efficiency of E-HRM at EGHTESAD NOVIN BANK’s Customer Relationship Management system. Furthermore, answer the following question: Can elements of cloud computing impact a CRM system’s effectiveness? As an additional innovation, a model for cloud computing banking and CRM was proposed and implemented. The results of employing questioners indicate that the cloud computing banking approach will be beneficial to banks’ prosperity. Before making the switch to the cloud, banks need to think about the following: data security, privacy, regulatory compliance, standard interoperability, and service quality. On-demand self-service, wide network access, resource pooling, quick elasticity, and measured service for business are a few of its benefits ( Mell & Grance, 2011 ). The cloud computing system, as defined by Buyya et al. (2009) , is a group of virtualized, networked computers that are dynamically provisioned and presented as one or more unified computing resources based on Service-Level Agreement (SLA) negotiated between the service provider and customers. Although there are many definitions of cloud computing, the following are particularly prevalent: 1) self-service interface; 2) elastic capacity and the appearance of infinite resources; 3) pay-per-use (no ongoing utility prices or commitments); and 4) virtualized or abstracted resources ( Avram, 2014 ). A cloud-enabled platform is essential for providing the agility, flexibility, innovation, and productivity required to meet expanding business demands, according to 89% of financial services executives today. The financial services sector is encountering difficulties in keeping up the rate of business growth as a result of macroeconomic instability and other market conditions. Consequently, a lot of businesses are actively embracing digital transformation, and in order to obtain a competitive advantage, they must deploy cloud-enabled solutions ( IDC, 2023 ).

In the digital age, cloud computing is a game-changing technology that has completely changed how banks handle, store, and analyze data. With the aid of cloud computing, banks can access a broad range of IT services and software programs to help optimize their operations and spur innovation. Streamline operations, banks able to satisfy the customers’ expectations. Banks won’t have to spend money on pricey hardware and software infrastructure or maintain sizable on-site data centers. The operational expenses of banks are significantly influenced by their IT infrastructure. At the same time, cloud computing presents the opportunity to transform security practices and improve defenses ( Sumathy & Anitha Rathna, 2018 ). Secure deployment options provided by cloud computing technology could help banks enhance their new customer experiences. It improves IT efficiency while enabling remarkable collaboration and quick time to market. An increasing number of industries, including banking, are showing interest in using cloud computing ( Foster et al., 2008 ; Lee et al., 2014 ; Marin, 2012 ). Pay-as-you-go models allow banks to access the computing resources they require, scaling up or down based on demand. Banks can respond more quickly and nimbly to shifting business requirements thanks to cloud computing, which eliminates the upfront expenses and ongoing maintenance requirements of traditional IT infrastructure. Banks can use cloud computing to enhance their operations in the ways listed below. It facilitates the banks’ ability to convert capital expenditure into a lower level of continuous operating expenses. Additionally, it saves money because financial institutions only have to pay for the services they use and functional consumption ( Patani et al., 2014 ). Additionally, financial institutions can benefit from shorter product development cycles due to the flexibility of cloud-based operating models. It offers a quicker and more effective way to address the requirements of bank clients. Moreover, cloud banking has streamlined innovation, efficiency, and customer-centricity in the banking sector in addition to simplifying digitalization. It has completely changed how banks function, accelerating development and providing a flawless banking experience.

On the other hand, Benton (2010) identifies two domains where cloud-based apps can help bank clients/customers. Second, in contrast to traditional client-server technologies that impose significant time, cost, and resource barriers ( Li and Li, 2011 ), cloud-based applications, specifically Software as a Service (SaaS), can assist bank customers in fulfilling their daily financial transactions more easily and without incurring additional costs ( Huang et al., 2011 ). On the other hand, users of cloud-based apps do not need to install software ( Marston et al., 2011 ). Banks can also benefit from increased fault tolerance, disaster recovery, and data protection. Not only does it offer more redundancy and backup than traditional managed solutions, but it also costs less. Through the transfer of their services to a virtual environment, cloud computing lowers energy consumption and its carbon footprint while also increasing computing power utilization efficiency and decreasing idle time. Large banks are very confident about the adoption of cloud technology and others are more careful and wait before jumping into this technology due to security and regulatory challenges. Although a bank may move to the cloud for a variety of reasons, applications will probably be the main driver. A survey on bank customers’ interest in 186 banking technologies was carried out in 2010 by Bank Systems Technology and Information Week Analytics. The majority of customers (73%) said that their interest stemmed from cloud services’ capacity to scale in the cloud and quickly respond to customer requests. However, it is anticipated that banks will lead the globe in SaaS solution nobility and cloud adoption. At the same time, banks must seek creative ways to satisfy business needs in today’s demanding environment due to strict financial constraints, a developed regulation ( Apostu et al., 2012 ).

Although the banking industry continues to have reservations about cloud technologies, the most common ones are security, privacy, data location, data integrity and confidentiality, availability, and user trust ( Bose et al., 2013 ; Rani & Gangal, 2012 ). However, it is anticipated that banks will lead the globe in SaaS solution nobility and cloud adoption. The way banks store, process, and analyse data has changed because of the revolutionary technology known as cloud computing.

Cloud computing offers on-demand access, requires fewer infrastructures, and requires less setup time. Purchasing a lot of new hardware and software is not necessary when using cloud computing. Thanks to cloud computing, the development of new products can continue without requiring a capital investment. It makes it possible for businesses to move non-essential services to the cloud, like software updates, maintenance, and other computer-related issues. Consequently, banks are able to concentrate more on their financial services business as opposed to IT. It’s critical to recognize that the financial industry has stringent regulations pertaining to cloud technology. Financial institutions handling data in the cloud are subject to several guidelines, directives, and standards. Banks can adopt cloud computing solutions at their peripheral businesses before progressively bringing them closer to their core operations. To enhance security and high availability of IT infrastructure and enable on-demand IT infrastructure services, large banks can begin with “private cloud. Based on this, they can progressively experiment with “public cloud” and “hybrid cloud.” Small banks have fewer resources than big banks in terms of capital, talent, technology, and other areas. It is also evident that setting up their own data centers is challenging due to the high expense. It would be wiser for small banks to use cloud service providers’ public financial cloud services ( Yan, 2017 ). A methodology for evaluating is the security of cloud computing in banks. It addresses every facet of cloud computing security and guarantees the creation of standard evaluation standards. The security requirements, obstacles, and challenges in the cloud for bank business are covered in this paper. After that, help banks find solutions to security-related issues in order to facilitate cloud adoption ( Martin et al., 2014 ).

Researchers Rieger and Schmacher (2013) developed the TOE model to look into the variables influencing German banks’ decisions to use cloud computing and to pinpoint the advantages and disadvantages of the technology from a manager’s point of view. The biggest determining factors are government regulations, followed by security, data location, and provider. The main justifications for using cloud computing are the alleged financial advantages. Bekele (2014) conducted a study that examines the internal and external factors that impacted the decision of IT executives and experts regarding the adoption of cloud computing in the banking sector of Ethiopia. PCA analysis was used in the research process to analyze data from both quantitative (survey) and qualitative (interview) sources. The TOE model was intended. The findings suggest that the following internal and external factors impacted the decisions made by IT executives and experts: employee skills, external pressure, cost, and cloud consistency; complexity, compatibility, and risk of failure.

Jiang and Yang (2011) explain the fundamentals, traits, and uses of cloud computing. They also examine the drawbacks of bank information systems and identify novel uses for cloud computing. They think that with the help of cloud technology, commercial banks will have enormous development potential. Researcher Modak and Walke (2013) talked about problems that banks have that need to be resolved before going cloud-based. Additionally, this paper highlights a few unresolved issues with cloud platforms, such as mobility, elasticity, and deployment. A few solution techniques are provided in the paper, including firewalls, honey pots, and intrusion detection systems (IDS). Awn and Ghilan (2021) carried out a survey on the adoption of cloud computing in the banking industry. It discusses the various adoption models for cloud technology, security, and privacy in banks, and it chooses the best model for cloud adoption in banks. Asadi and Yadegaridehkordi (2016) in their study conclude that perceived usefulness, perceived ease of use, cost, attitudes toward cloud and trust significantly influence users’ behavioral intention to adopt cloud computing. The study concludes that the banks enable to focus more on customer perspectives on cloud-based applications and identify their attitude towards their adoption. In their research, Alexandru et al. (2013) examine and contrast a number of the most widely used online banking platforms while also analyzing the Romanian online banking industry. Include conclusions about this cloud computing market as well. Analysis results indicate that Internet banking needs to be redesigned to be more flexible and efficient in meeting customer needs. They noticed that cloud services are the answer to organization demand. Tesema (2020) seeks to determine the difficulties and concerns related to security, privacy, and availability of cloud computing in Ethiopia’s Commercial Bank. Using case studies of major banks, the researchers employed a descriptive methodology to investigate and evaluate the role of cloud computing in Ethiopia’s commercial banks that generate robust and economical solutions to the present issue. Major factors like cost-effectiveness, security and compliance, reliability, interoperability, and regulation have an impact on cloud adoption in CBE. After stating that the global economic crisis has affected Russia’s banking system, Bataev (2017) addresses the use of cloud technologies by Russian banks. The essay also examined the fundamentals of cloud computing and examined the variables influencing cloud adoption in Russian banking. The results of this study show that over 52% of Russian banks do not use cloud services, and that the country’s banking sector is implementing cloud technology rather slowly. In the study, Bejju (2014) provided an overview of cloud computing and suggested a business plan to lessen the constraints of cloud-based technologies. Examine the shortcomings of the current banking system as well as the creative ways that cloud computing is being used in banks. The difficulties in adopting cloud computing, including those related to security, regulatory compliance, data segregation and privileged user access, long-term viability, and recovery, were also covered in the paper. A survey on cloud computing adoption in the banking sector was conducted by Awn and Ghilan (2021) . It addresses the different models of cloud technology, security, and privacy adoption in banks and selects the most effective model. Furthermore, our paper explores challenges and optimal methodologies associated with cloud computing adoption in the banking sector. The study’s conclusion is that the TOE model was identified as the common model across studies that had an impact on banks’ adoption of cloud computing.

Nedelcu Bogdan et al. (2015) highlight the current status of the cloud computing infrastructure. Answer the question, “Is cloud computing safe?” by weighing the benefits and drawbacks of the security system. Highlight the advantages of cloud computing security. Discuss the many cloud service models, cloud computing security issues, and complex data security issues in the cloud. Discover ways to protect data in the cloud and its advantages, disadvantages, and possibilities. From the above previous empirical investigations of various studies, we could able to understand the use and adoption of cloud computing in the banking sector. This technology more useful to the banks to full the requirements of customer expectation, as a result of technological advancement. The above studies are proved that the benefits and challenges of cloud computing technology adoption in the banking sectors. Some studies address the different models of cloud technology which is more effective models. Studies identified major factors that have an impact on cloud technology adoption in banking sector.

According to Sunami (2017) , weigh the advantages and disadvantages of the current core banking systems and compare the design architecture of the cloud-based core banking system with bank architectures currently in place. Additionally, the researchers proposed architecture for a cloud-based core banking system that can be used to automate a range of cloud-based banking services. The study’s findings indicate that critical systems’ security issues may need to be discussed with vendors, which may limit some applications to the IaaS or PaaS models.

However, there are certain drawbacks to cloud computing, like expense and security. Figure 3 depicts that the cloud service delivery models used to four path.

First model, Business Process-as-a-Service (BPaaS): According to Lara Greden, research director at Platform as a Service at IDC, “the fundamentals of cloud technologies and public cloud PaaS providers as strategic partners to enterprises and companies of all sizes are evident as AI pervasiveness strengthens.” Billing, payroll, and human resources are all common business processes that are carried out in the cloud. All of the other service models are combined with process expertise in BPaaS. With the help of second model Software-as-a-Service (SaaS), users can access the business software and data through their web browsers, which are hosted by a cloud service provider. Accounting, customer relationship management, enterprise resource planning, invoicing, human resource management, content management, and service desk management are examples of software that can be delivered this way. Third model named as Platform-as-a-Service (PaaS), a complete platform for application, interface, and database development, storage, and testing is provided by a cloud service provider. By streamlining the development, upkeep, and support of custom applications, businesses can cut down on IT expenses and use less hardware, software, and hosting environments and from the fourth model Infrastructure-as-a-Service (IaaS), lets businesses buy resources like servers, software, data center space, and network equipment as a fully outsourced service instead of buying them themselves.

From the below Figure 4 , we could be able to understand that there are three ways service providers most commonly deploy clouds:

It’s an internet-based cloud infrastructure shared by several organizations under

the management of outside cloud service providers. All hardware and software are owned and managed by the cloud provider, and subscriptions are used to gain access to this space.

In this scenario, banks have access to both private and public cloud infrastructures, enabling data and applications to move back and forth between them. Less important data is kept in a public cloud area, whereas sensitive data is kept in a private one. At the moment, 78% of business used a hybrid cloud strategy because they understand that the particular requirements of financial institutions cannot be satisfied by depending only on a private or public cloud. A hybrid cloud combines the control and security of a private cloud with the scalability and flexibility of a public cloud ( Twarogal, 2024 ).

Managed within a private network, a private cloud is built specifically for a single financial institution. It may be hosted by a third party or kept in the bank’s own data center. Private clouds are generally advised for banks due to their increased control over security and data.

The first half of 2023 (1H23) saw $315.5 billion in worldwide revenue for the public cloud services market, up 19.1% from the same period in 2022, according to new data from the International Data Corporation (IDC) Worldwide Semiannual Public Cloud Services Tracker.

From the below Table 1 , we could be able to understand clearly Software as a Service (SaaS) applications, which accounted for almost 45% of all revenue from public cloud services in 1H23, remained the main source of income. The second-biggest revenue category was Infrastructure as a Service (IaaS), accounting for 20.4% of the total. Platform as a Service (PaaS) and Software as a Service-System Infrastructure Software (SaaS-SIS) contributed 18.0% and 16.9% of the total revenue, respectively. The categories with the fastest revenue growth year over year were PaaS and SaaS-SIS.

Source: IDC worldwide semi-annual public cloud services tracker, IH2023, November 30, 2023.

With 41% of global revenue coming from the top 5 public cloud service providers (Microsoft, Amazon, Web Services, Google, Sales force Inc., and Oracle), the top providers of public cloud services held onto their positions in 1H23. This revenue growth was largely consistent year over year. Microsoft maintained its leading position in the public cloud services market in 1H23 with 17.1% share, followed by Amazon Web Services with 12.6% share, both of which had offerings in all four deployment categories.

Global revenue from public cloud services is expected to reach $663 billion in 2023, up 20.0% from 2022, according to IDC forecasts. A comparable increase is anticipated in 2024. It is anticipated that the market will grow at a five-year compound annual growth rate (CAGR) of 19.4%, with global revenues expected to reach $1.34 trillion in 2027, despite a slight slowdown in growth over the forecast period.

The third aspect of choosing the right cloud services delivery model is determining the appropriate operating model for the required mix of resources and assets. From the above Figure 2 , we could be able to identify clearly three operating models for cloud services.

Financial firms can gain cloud expertise by hiring people with the right skill sets from service vendors. The additional staff can be housed in the firm’s existing offshore captive center. This operating model allows for flexibility and lets firms choose the best resource for each specific requirement.

Virtual captives have a dedicated pool of resources or centers to help with cloud operations and meet demand. This operating model is a good alternative to a complete outsourcing approach.

This approach uses offshore centers, facilities, and people from a third-party vendor to handle cloud operations. The model combines resources and investments to cater to cloud services for multiple banks.

Using cloud computing in banking removes the need for spending on infrastructure, security, and storage maintenance. Consequently, there’s no need for a special team to handle these tasks, freeing up resources for other pressing business priorities. According to the Economist Intelligence Unit report, cost reduction is the biggest driver of cloud adoption, with 42% of respondents citing this as a key factor.

Bank operations are revolutionized by cloud computing. By simplifying procedures and giving users immediate access to software updates, it increases their agility and responsiveness to changes in the market. According to a Capgemini survey, 78% of banking executives believe that implementing cloud computing can improve the flexibility and productivity of their companies.

One of the main advantages of cloud-based hosting is its effortless resource scaling. A company that builds out its cloud infrastructure also inevitably grows its applications and services while catering to its current clientele. The cloud system in this case needs to be scalable to meet these changing requirements. By automatically adjusting resource allocation to changing workloads, auto-scaling further streamlines this process and ensures optimal performance without the need for manual intervention.

By automating routine tasks like backups and updates, cloud technology reduces human error and manual labor while increasing operational efficiency.

Banks can now provide their clients with convenient, anytime, anywhere access to banking services through mobile or web applications thanks to the cloud. High Availability (HA) techniques make sure that these services keep running even in the event that some of their components malfunction. After all, accessibility is paramount in the modern digital world.

Banks can take advantage of cloud-based server less services, which provide easily scalable, affordable, and on-demand solutions. Developers can relax about infrastructure with server less computing, since the cloud service provider takes care of resource management, scalability, capacity, and patching.

Cloud banking makes it possible to allocate computer resources quickly, allowing for prompts responses to demand spikes. Cloud infrastructure has the flexibility to grow services or storage without being limited by a lack of physical resources, allowing it to scale elastically to accommodate varying workloads. Additionally, banks are able to reduce resources when not required, which optimizes expenses and allows for a degree of agility that is challenging to achieve with on-premises systems.

Prominent cloud providers, in contrast to popular belief about cloud vulnerability, employ sophisticated security procedures that are outside the purview of individual businesses. Strong access controls, data encryption, network security, controls at the application level, and sophisticated threat detection are a few of these. Additionally, cloud providers conduct thorough penetration tests and compliance audits. Banks can take advantage of cutting-edge security while lessening their internal security burden by utilizing the cloud.

For banks, cloud computing scalability and flexibility are essential tools for fostering a culture of ongoing innovation. Banks can allocate resources dynamically to create and introduce new digital banking products by utilizing cloud services. Because of their agility, banks are able to quickly prototype and test proofs-of-concept and improve their services in response to real-time customer feedback. The cloud facilitates this iterative approach to product development, which speeds up the rollout of improved services.

Cloud computing spreads data across several geographically dispersed data centers, improving a bank’s business continuity and disaster recovery capabilities. By doing this, operations are guaranteed not to be disrupted by nearby events, ensuring continuous service availability. In order to reduce downtime, cloud providers also include built-in redundancy for crucial systems. Banks can strengthen their reputation for stability by offering dependable access to banking services through the use of the cloud.

The banking industry is still quite concerned about cloud technologies. The most important of these concerns are security, privacy, data location, data integrity, confidentiality, availability, and user trust ( Bose et al., 2013 ; Rani & Gangal, 2012 ). According to Catteddu and Hogben (2009) , barriers such as data privacy and data security are the major hindrance of SaaS adoption. Banks are categorized as a very high-risk level and sensitive organizations ( Jain & Bhardwaj, 2010 ). Because cloud computing denies users direct control over the systems handling their data, cloud-related anxieties may surface ( Shekhawat & Sharma, 2011 ). Naturally, banks want to store more data on “the cloud” in order to reduce resource consumption and increase revenue. However, more data means more potential for misuse when it comes to “cloud” storage. Many banks will be hesitant to decide because of this predicament. Data security is of utmost importance in banking; moving workloads to a shared architecture will undoubtedly raise the risk of unauthorized access and data leaks. In addition, many financial executives have doubts and concerns because of the cloud computing concept that emphasizes “users do not need to worry about the physical location of the data but only to care about how to use” ( Zhang, 2010 ). It is challenging to win banks’ confidence in cloud computing if the “security” barrier is not overcome as quickly as feasible.

Public cloud providers are aware of their clients’ worries about accessibility and security. In certain jurisdictions, regulatory requirements dictate the location of data storage, so adhering to these requirements may limit the selection of cloud providers capable of fulfilling these requirements.

It’s common for the expenses associated with implementing and sustaining cloud services to be unforeseen and underestimated. Moreover, at least half of the banks encountered cost overruns in comparison to their original estimates in crucial areas like legislation, departmental support, re-architecting, and external contractors. This demonstrates the difficulty financial institutions have in precisely calculating and controlling the expenses related to cloud adoption.

It can be difficult to maintain governance and control over IT resources in a cloud environment. To manage cloud resources, guarantee appropriate oversight, and uphold compliance with internal and external policies, banks need to set up explicit policies and procedures. Banks should use DevSecOps tool chains and cloud management platforms to further improve governance by offering continuous compliance, centralized control, and automation across hybrid cloud environments.

A significant amount of data is generated by banks. It can be difficult and time-consuming to move everything to the cloud and guarantee its portability across various cloud service providers. Nine out of ten companies are thought to struggle with cloud migration. Although it can take up to 15 months on average, larger banks should anticipate much longer wait times.

It can be difficult for banks to smoothly integrate their legacy systems with cloud solutions. It can be challenging to ensure compatibility between the new cloud environment and the antiquated system. Legacy systems frequently use antiquated operating systems, programming languages, and technologies that may not be compatible with cloud infrastructure. It is very difficult to achieve this integration without any problems.

On the other hand, the unrelenting pursuit of high availability might present unique difficulties. Relying only on a vendor for redundancy assurance could result in problems like service disruptions, downtime, and disagreements over contracts. This may have an effect on the smooth provision of services to clients and jeopardize the advancements in client care.

Because these services are public and multi-tenant, they may not be appropriate for critical banking applications, despite their power. Banking executives are concerned because navigating the complex regulations governing the finance industry becomes even more difficult in the cloud. If cloud migration isn’t approved by regulators, there could be penalties and harm to one’s reputation. Additionally, with programs like the General Data Protection Regulation (GDPR), open banking, Know Your Customer (KYC), and anti-money laundering, international regulators are adopting a more proactive stance.

The dynamic nature of the cloud and its widespread accessibility can introduce new vulnerabilities and potential attack vectors, even though cloud providers generally offer strong security features. To safeguard consumer data and uphold the integrity of their financial services, banks must constantly update their security procedures and remain alert to new cyber-security threats. Furthermore, banks can proactively fortify their defenses throughout their cloud ecosystem by implementing a zero-trust strategy that is strengthened by analytics-driven threat detection and automated response capabilities.

Latency problems can impact the performance of cloud-based applications, especially if cloud data centers are situated distantly from end users. Banks must make sure that the cloud architecture they have chosen minimizes latency for vital applications, particularly transaction systems that demand real-time processing. Low latency and consistent performance can be achieved by combining edge computing, distributed caching, predictive scaling, and sophisticated traffic monitoring tools for traffic management.

From the above discussion, how it performs best practices of cloud computing adoption in the banking industry. It concludes that the banking sector enjoys cost, enhanced agility, operational efficiency, improved customer satisfaction, safety and innovation. Even though, banking sector facing challenges such as complexity in data migration, cyber security issues, disruption in the customer service and non-compliance issues when it adopts cloud computing.
