This blog article will examine shared attributes of high availability (HA) and fault tolerance (FT). Some of the most important elements include: No single point of failure (SPOF): You must eliminate any SPOF in the database environment, including any potential for an SPOF in physical or virtual hardware.

Defining high availability In general terms, high availability refers to the continuous operation of a system with little to no interruption to end users in the event of hardware or software failures, power outages, or other disruptions. It also supports the flexibility and scalability of the database infrastructure.

Above that there’s a deployment platform such as Kubernetes or AWS Lambda.
