“Obviously, there are a lot of benefits. But if I would have to choose there are three pivotal differentiators to use cloud native technology over on-premise or adjusted-for-the-cloud technology.
Firstly, when looking at the technology side only, working with Microsoft Azure cloud provides a vast array of services, which are managed by Microsoft. These services offer many options for your application design and lower the threshold to try something new, due to the accessibility of pre-developed functionalities.
Secondly, scalability is a significant advantage of cloud technology. Banks are able to scale to demand way faster than with on-prem or cloud-adjusted technology. Being less dependent on the maximum output, enables them to even ‘hyper-scale’ if the capacity is needed, but at the same time lower the capacity to reduce cost and efforts.
The third point is security, which until recently was not the first thing you would link to cloud technology. The security of the cloud is on a higher standard thanks to the billions of dollars that providers like Microsoft, AWS, and Google spend on it each year. They have to be on par with regulations, keep hackers out the door and conversely keep the system accessible and easy to distribute. The investments that the cloud providers make in security allow us to build a secure platform in the cloud, managed for our clients. This leads to companies spending significant amounts of money on security.”
“It’s always tricky to predict future trends and future requirements in tech. Who would have thought 20 years ago that everyone would have a powerful computer in their pocket all the time?! But looking at what makes cloud technology future-proof, I would say the sheer power of the cloud platforms. The power of these platforms lies in multiple things. They offer an easy way to scale so you can be sure that whatever the load on your system will be, you can scale. They offer robust security, so you can be sure that your data is secure. Finally, maybe the most important part is the fact that the cloud providers offer a lot of
value-added services out of the box. These services range from data analytics to AI services allowing you to build systems and use your data in ways that were hard, if not impossible in the past.
To stay future-proof I would say the most important thing is for the cloud providers to keep adding value-added services, and to maintain the trust they have built through the past few years.”
“The biggest decision we made was regarding orchestration. In the past, we learned that good orchestration is key for banks because, in the end, banks are essentially a collection of processes and a stable orchestration helps to digitize and automate them. When we sat down to think about that piece of functionality, one option was to build it ourselves, which would have been time-consuming and expensive. Then, we looked at the services that Microsoft Azure had to offer and realized that Logic Apps was a really good fit for us. The Business Process Management (BPM) functionality of Logic Apps was of course not made for banking and needed some finetuning, yet it came very close and was easy to build on top of, and was easy to integrate with our own architecture.”
“Security is a topic to nominate if we are talking about relevancy. Security is an extremely large hurdle for banks to tackle. In turn, it should also be a key motivator to move to the cloud. Usually, the core systems used by banks are quite old. It is not uncommon to have to go offline with the system to calculate end-of-day results at which time you will not be reachable as a bank. With a cloud system, this is not needed, and you can always be available for your customers. Nowadays, it is normal to check your bank account in the middle of the night, which with those old systems sometimes is not possible.
Also, cloud native systems enable banks to do disaster recovery way easier. As the cloud is global, if anything happens, you can switch to another region to prevent downtime, which conversely enables you to service your clients with 24/7 availability.”
