What is cloud computing in banking

In the spectrum of modern financial services, cloud computing has navigated the transition from the complexity of traditional IT infrastructure to today’s flexibility and scalability. Freed from old-school computers and cumbersome servers, which were not only expensive but also required extensive maintenance, banking operations have become faster and smarter. Today, all the complex data and transactions are conducted in the cloud – a virtual environment where banks can leverage the necessary computing resources, including servers, storage, databases, networking, and analytics software for storing, managing, or processing data without being required to own them.  

When it comes to adopting cloud services, banks have unique considerations. The choice of the model is influenced by factors such as cost, compliance, security, and operational needs. Below are the primary cloud environments banks can choose from:

Public cloud

Banks can tap into resources provided by third-party cloud service providers via the Internet. These services are shared with other organizations and are ideal for non-sensitive operations, offering cost efficiency, high scalability, and a broad selection of services that reduce the need for substantial investments.

Private cloud

For operations that involve sensitive data or require more stringent control and security, banks can use a private cloud. This can be hosted internally (on the bank’s premises) or externally by third-party providers, but it remains exclusively for the bank’s use. The main benefit of a private cloud is enhanced security and the ability to tailor resources to specific banking workflows.

Hybrid cloud

To optimize flexibility, banks can employ a hybrid cloud strategy. This involves integrating public and private clouds, allowing data and applications to move seamlessly between the two environments. This model is particularly advantageous for balancing agility, cost efficiency, and regulatory compliance.

Community cloud

In specific scenarios, community clouds offer collaborative infrastructure shared between several organizations with common concerns (such as security, compliance, and performance requirements). This is particularly beneficial for smaller banks or financial institutions that require specialized services but want to share costs.

Service models offering precision and efficiency

Cloud banking services are offered under various models, each designed to align with different aspects of the banking infrastructure:

Infrastructure as a service (IaaS)

This is the foundational layer of cloud services, where banks can rent computing power and storage on-demand, eliminating the capital expense and maintenance requirements associated with hardware ownership. IaaS provides banks with the raw materials of IT infrastructure, offering flexibility and scalability as they grow or face fluctuating demand.

Platform as Service (PaaS)

PaaS takes things a step further by providing banks with a complete development and deployment environment in the cloud. This includes tools for building, testing, and deploying banking applications quickly and efficiently. This option is ideal for banks looking to develop new services or apps without the overhead of building and maintaining the underlying infrastructure.

Software as a service (SaaS)

In the SaaS model, banks access applications hosted by service providers over the Internet. This eliminates the need for installing and running these applications on individual bank computers, simplifying maintenance and support. SaaS solutions are typically subscription-based and can range from core banking systems to customer relationship management (CRM) tools.

By capitalizing on these cloud computing models and services, banks are not only able to modernize their IT environment but also align their operations with the harsh demands of the finance sector.
