In recent years, there has been a significant increase in the number of companies offering cloud computing and storage services. The reason is the many potential benefits and advantages of cloud computing.
Amazon Web Services is one of the providers offering this service. AWS (Amazon Web Services), founded in 2006, is the world's largest provider of cloud computing and storage services, among others such as Google (Cloud Platform), Microsoft (Azure) and IBM (SoftLayer, Bluemix).
Reasons why AWS is preferred:
- As with all cloud systems, AWS has designed all its modules separately, but in a way that delivers superior performance when they come together.
- Having each of them as a separate module significantly increases the system's performance.
- The high security and high service level it offers create customer satisfaction.
Cloud use in the financial sector
When using the cloud, banks and payment institutions assess topics such as data location, access control, encryption and provider management according to the regulations. The cloud provider protects the infrastructure, but application and data security remain the customer's responsibility. This is called the shared responsibility model.
For systems that process card data, PCI DSS compliance must also be ensured. That is why cloud selection is assessed not only on cost and performance, but also on compliance and auditability.
In architectural decisions, multi-region setups, backups and an exit strategy should be planned from the start.
