Redundant Implementation (Erl, Naserpour)
How can the reliability and availability of a microservice be increased?
Multiple implementations of microservice deployments with high usage requirements or providing critical functionality can be created to better guarantee high performance, availability and increased reliability, even when unexpected exceptions or outages occur.
Having redundant implementations of microservices provides fail-over protection should any one implementation go down.
This pattern can be applied in different ways, depending on how microservices are redundantly deployed, as explained in the complete pattern description.
