Redundant Implementation (Erl)

How can the reliability and availability of a service be increased?

Problem

A service that is being actively reused introduces a potential single point of failure that may jeopardize the reliability of all compositions in which it participates if an unexpected error condition occurs.

Solution

Reusable services can be deployed via redundant implementations or with failover support.

Application

The same service implementation is redundantly deployed or supported by infrastructure with redundancy features.

Impacts

Extra governance effort is required to keep all redundant implementations in synch.

Principles

Service Autonomy

Architecture

Service
Redundant Implementation: Having redundant implementations of agnostic services provides fail-over protection should any one implementation go down.
