In case you concerned about security, you may end up with building your own on premises cluster or even couple of them. Once you made this decision, you may face problems of distributed systems you never thought ever existed. I’ll tell how we transformed enterprise “old-schoold” company, with technology stack from 90th into modern company, with high availability and reliability in mind. Why we choose SaltStack and Kubernetes for our stack. What problems you may face working for “enterprise” company with open source tools. How we made error proof deployment, and how you can do the same.
I’m system architect at Oberthur Technologies, where I design clustered environments. I have started my career as shift engineer, and that changed my mindset to always think about operation in production. With more than 12 years of experience with production systems, my expertise varies from legacy systems to highly available real-time clusters. I can tell a lot how not to build your system 🙂
