Single service instance per host pattern
This is another service deployment pattern. There are requirements and scenarios wherein multiple instances of a service are deployed on a single server. On the other hand, there are needs for deploying only one instance and running it on a host machine. The benefits of this approach include:
- Service instances are fully isolated from one another
- There is no competition for resources and the issues being associated with dependencies are no more
- A service instance can consume at most the resources of a single host
- It is easy to monitor, manage, and redeploy each service instance
The drawback is that the resource utilization may decrease.
