What is Cloud Banking?

Banking on cloud is a model of banking services that uses cloud computing technology. These services are delivered remotely through cooperation with the cloud service provider, not “locally” by the bank itself. This way, banks can constantly offer their services on the Internet without interruption. This translates into the availability of banking services at the highest level for customers and reducing operating costs for banks.

Cloud for banking – advantages of using cloud in the banking sector

The banking sector is facing challenges related to growing customer expectations, regulatory requirements and the need for continuous innovation. Cloud computing offers banks several benefits that can help them meet these challenges.

Banking cloud and scalability, flexibility and innovation

Flexibility and scalability are key features of the cloud. They allow banks to quickly adapt to changing market conditions and customer needs. They can increase or decrease cloud resources according to the current demand, which is especially useful in managing fluctuations in demand for financial services. For example, banks use cloud computing to scale transaction systems during peak demand periods, i.e., at the beginning and the end of the month or on holidays.

Innovation is another paramount issue. The cloud offers access to the latest technologies, such as artificial intelligence, machine learning and natural language processing. Thanks to that, banks can benefit from advanced tools to analyze data, manage risk better, automate processes, and create new, innovative products and services. In addition, the existing systems and applications are modernized, considering their partial migration to the cloud.

Cloud in banking – implementation and access to API

Cloud banking facilitates the implementation of new solutions more quickly. Banks can quickly test and train new apps and services from specific cloud providers, significantly reducing the time to market (T2M) for innovation.

You can also access the API systems, i.e., the application programming interface. It’s a set of guidelines that outlines how different programs and subprograms work together in a given environment. This enables banks to integrate with various applications and services for efficient data exchange and collaboration with external partners. Also, it may entail process automation, streamlining operations, and creating new distribution channels.

Banking in the cloud and dynamic changes

Competitiveness is essential in a dynamically changing market environment. The cloud allows you to adapt to new trends and customer needs quickly. 

The cloud also gives you the opportunity to introduce attractive offers to the market, which are tailored to the individual needs of customers. This can help to increase their satisfaction and loyalty.

Cloud for banking and the forms of implementation – public cloud, private cloud and the hybrid model

Banking solutions can be implemented and maintained in various forms. The on-premise model relies on the fact that the entire infrastructure or system is set up on servers in the bank. In this case, no cloud is used. Another option is the hybrid model, which combines the benefits of both the cloud and on-premise models. This balanced approach provides greater control and security offered by the on-premise model while also taking advantage of the cloud flexibility.

on-premise model– more control over data security
– no sharing of resources with other companies
– independence from the external supplier
– control over processes
– limited flexibility and scalability
– need for self-management and maintenance of infrastructure
hybrid model– flexibility and scalability
– sustainable data security
– cost optimization
– increased operational efficiency
– more complex management
– risk associated with the integration oflocal and cloud data
– dependence on cloud providers
– implementation and maintenance costs

Cloud-based banking solutions can use public or private clouds. Each offers unique features and advantages, as shown in the table below. 

public cloud– available in the public domain
– used to share servers, store data and applications
– fast access to massive amounts of data
– scaling of services when needed
– cost savings
– ease of implementation
– risk concerning data security
– limited control over the environment in which applications run
– dependence on the supplier
private cloud– created exclusively for the use of one company, institution, or organization– resources can be managed by both the external cloud provider and the organization itself
– high level of security
– protection of privacy
– good control of resources
– higher maintenance costs
– less flexibility
– complex management
– less global scalability

The choice of a suitable cloud model in banking depends on the specific needs and security requirements of a given bank. Various models offer different benefits and pose different challenges to banks.

Cloud banking system – efficient implementation and adaptation

Cloud-based banking solutions are currently being intensively implemented. They cover many aspects of banks’ activities. Banks worldwide, including Poland, are actively testing cloud solutions, which is a significant change in how the financial sector operates. Many of these initiatives occur on platforms like Platform as a Service (PaaS) and Software as a Service (SaaS).

PaaS cloud banking, also known as a cloud-based banking platform, is a software delivery model that provides cloud-based infrastructure and platform services to create, deploy, and manage financial apps. Such platforms enable banks to develop and manage applications without dealing with infrastructure, which is particularly useful for rapid deployment of new services. Meanwhile, the SaaS (Software as a Service) model offers ready-to-use apps on the Internet, reducing the need for software development investments.

As part of cloud adaptation, banks often start by implementing systems that are important but not key elements of their business. An example is business communication tools that facilitate office work. Such cloud solutions allow improving work efficiency and support employee mobility without exposing critical banking operations.

At the same time, banks are also considering approaches to more complex and significant systems. This applies to both their possible modernization as well as considerations on cloud migration or a wide-ranging transformation. Security, regulation, and the potential impact on key banking operations are taken into account when making these decisions.

Cloud adoption in banking – factors affecting the success

Cloud migration success factors go beyond IT technologies. A crucial element of this process is the human factor, i.e., specialists – their knowledge and skills are necessary to optimize the entire migration process. The competencies of professionals in cloud management, data security and systems integration are essential for a successful transition to cloud infrastructure.

Approaches to cloud migration in the banking sector may vary, but a common element is prioritizing tasks. Each migration stage must be carefully planned and implemented according to a fixed priority hierarchy. This approach enables efficient management of resources and minimizes the risk of disruptions in the bank’s operations.

External technology partners also play a vital role in cloud migration. They are responsible for planning migration, setting priorities and ensuring security.  The enterprise must choose the right partners with experience and expertise in banking and cloud technologies to succeed. Partnering with trusted cloud providers and consultants can make the transition to the cloud significantly easier, ensuring that all aspects of migration are properly managed and secured.

Cloud banking – increased awareness and interest

The increase in banks’ awareness and interest in cloud solutions in recent years is a phenomenon visible on a global scale. This trend is particularly noticeable in large international financial organizations, which are increasingly adopting a multi-cloud approach. They use services delivered by multiple cloud providers. This approach brings many business benefits but also poses new challenges for organizations.

The benefits of multi-cloud include greater flexibility and the ability to tailor services to your specific business needs. The diversity of providers can also contribute to increased reliability and continuity of service operations, as the risk of service interruptions is spread between different operators. In addition, multi-cloud enables banks to take advantage of the best solutions and technologies available on the market, which can contribute to a competitive advantage.

However, multi-cloud infrastructure poses challenges such as monitoring and cost optimization. This requires conscious management of resources to avoid excessive spending on unnecessary services or resources.

The use of multiple cloud operating environments increases the likelihood of a potential security breach. Maintaining consistent security policies across different clouds and managing access while ensuring a uniform security standard poses a big challenge. What is more, integrating various services and data from multiple clouds can become complicated due to the differing standards and protocols used by service providers, which can lead to operational issues.
