Understanding Contrail Microservices Architecture

What is Contrail Microservices Architecture?

Employing microservices provides a number of benefits which includes:

• Deploying patches without updating the entire Contrail deployment.

• Better ways to manage the lifecycles of containers.

• Improved user experiences with Contrail provisioning and upgrading.

• Provisioning with minimum information provided.

• Configuring every feature.

• Simplify application complexity by implementing small, independent processes.

The containers and their processes are grouped as services and microservices, and are similar to pods in the Kubernetes open-source software used to manage containers on a server cluster.

Figure 1 shows how the Contrail containers and microservices are grouped into a pod structure upon installation.
