5. key takeaways
1. Public and hybrid clouds, and 3rd party APIs are more popular in the financial sector than elsewhere as a
means of storing data. Nevertheless, private cloud and on-premise servers remain at the top.
2. Professionals in the financial sector use multiple backend technologies. Containers, container
orchestration tools, IaaS and legacy enterprise systems are used far more in this sector than in others.
3. Cloudification is as relevant in financial services as elsewhere. Developers in the financial sector are more
likely to be cloudifying multiple apps at a time.
4. Improving scalability/performance, improving reliability and outdated technology stacks are key reasons
for cloudification in the sector. Security, as a reason for cloudification, is as important here as in other
sectors, and ranks among the top-5 reasons.
5. DevOps practices are widely adopted by financial institutions and banks. This implies they have adopted
streamlined software delivery processes in an attempt to remain nimble in a highly-regulated
environment.
6. Blockchain other than cryptocurrencies is of higher interest to developers in the financial sector than
others, while 5G is not that interesting to them.
