On the extreme end of the modernization continuum are microservices. Microservices are a architectural approach where the applications are composed of independent services separated by a contract such as an API. Each microservice has a specialized function and may adhere to the twelve-factor application framework including having their own backing services.

Modernization through microservices.

Microservices bring additional challenges to the operations of an application including orchestrating the deployment of many components across fault domains and providing service discovery between components. Kubernetes provides a container orchestration solution capable of managing containers across hosts and providing a cloud native platform with service discovery. VMware provides Tanzu Kubernetes Grid to all VMware Cloud customers to run their container-based workloads in a vSphere environment. Tanzu Kubernetes Grid can also be used across native cloud environments to keep a consistent Kubernetes runtime across clouds.
