Hi Team,
“We are planning to set up a highly available (HA) Kubernetes cluster tailored for a financial domain, ensuring etcd availability and resilience. Kindly guide us on the best practices, prerequisites, and the ideal starting point for the setup.”
What type of infrastructure will you use, AWS, Azure, or on-premises?
For high availability and backup/restore out of the box, you are advised to use one of the managed cloud offerings (EKS, AKS, GKE) unless company policy dictates that you must run it in-house. It will save much effort.
Before attempting to build any cluster, especially one that is going to work with sensitive financial data, your team should contain at least one experienced Kubernetes architect or engineer, or you are going to have difficulties.
