Query: Kubernetes as an Availability Manager for Microservice Applications   The move towards the microservice based architecture is well underway. In
this architectural style, small and loosely coupled modules are developed,
deployed, and scaled independently to compose cloud-native applications.
However, for carrier-grade service providers to migrate to the microservices
architectural style, availability remains a concern. Kubernetes is an open
source platform that defines a set of building blocks which collectively
provide mechanisms for deploying, maintaining, scaling, and healing
containerized microservices. Thus, Kubernetes hides the complexity of
microservice orchestration while managing their availability. In a preliminary
work we evaluated Kubernetes, using its default configuration, from the
availability perspective in a private cloud settings. In this paper, we
investigate more architectures and conduct more experiments to evaluate the
availability that Kubernetes delivers for its managed microservices. We present
different architectures for public and private clouds. We evaluate the
availability achievable through the healing capability of Kubernetes. We
investigate the impact of adding redundancy on the availability of microservice
based applications. We conduct experiments under the default configuration of
Kubernetes as well as under its most responsive one. We also perform a
comparative evaluation with the Availability Management Framework (AMF), which
is a proven solution as a middleware service for managing high-availability.
The results of our investigations show that in certain cases, the service
outage for applications managed with Kubernetes is significantly high.
