    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.  

    what is cloud banking

    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.
