One of the new banks in my country (founded in 2018) decided to use a mainframe for all their core functionality. The actually have statement about it on their website: """ Many factors from cost to regulatory requirements to cryptography and other security requirements play a role in making a decision to run a core banking platform in the cloud. Whilst the cloud is good for managing certain services (which we indeed use), it becomes a challenge to manage a bank’s core banking platform. Once infrastructure is in a cloud, it is outsourced to that cloud provider. That means that the business is bound by those agreements covering aspects such as scalability, usage, capacity-on-demand and disaster recovery. These costs could grow exponentially as volumes grow. By using our own infrastructure for our core banking platform, we have full control over these factors. Our chosen mainframe solution provides the ability for us to grow exponentially, while controlling all factors (CPU, Memory, Disk, Network, DR, Remote capability, etc) allowing us to manage the environment efficiently and effectively.
