Single Node Multi-Containers (Erl, Naserpour)

How can multiple microservices be aggregated to provide a high-performance service composition?

Problem

The need may arise to aggregate a set of existing microservices to provide an API that offers high-performance functions to service consumers. However, to invoke and aggregate separate microservices introduces runtime overhead that can prevent fulfilling high-performance requirements.

Solution

All composition participants are deployed in individual containers allowing each to scale independently and as required to fulfill high-performance requirements.

Application

The Microservice Compositor pattern is applied to establish a set of microservices responsible for the composition logic. These and the other participating microservices are further deployed in separate containers on the same underlying host.

The microservices providing the composition logic as well as any composed microservices are deployed in individual containers and reside on the same underlying host. This enables all involved microservices to share the same host while retaining their individual logical isolation and without sharing any runtime. The service compositor is then deployed on the same host.

Single Node Multi-Containers: The microservices deployed in isolated containers on the same physical host. The underlying host can optionally be a virtual machine.

This pattern is applied in conjunction with the Microservice Compositor pattern as explained in the complete pattern description.

This pattern is covered in Module 10: Advanced Microservice Architecture & Containerization..
