Support for Kubernetes on Linux
InfoScale Enterprise supports Kubernetes to orchestrate and schedule containers in InfoScale clusters. While containers virtualize the applications from the underlying virtual or physical infrastructure, Kubernetes orchestrates, and scales containerized applications in real time.
InfoScale provides the following advanced functionality for containers and Kubernetes that enterprise applications need:
Application availability - High availability (HA) of data is one of the prime considerations when you plan for business continuity in case of disasters. InfoScale manages HA and recovery automation for your applications by monitoring critical application processes and resources. InfoScale provides persistent storage for stateful container applications. InfoScale fencing and arbitration prevent data corruption and speed up recovery. The use of VCS agents and persistent volumes ensure that there is no loss of data when containers fail. Consequentially data is always available no matter where the containers are scheduled in the container ecosystem.
Advanced storage management - The InfoScale Container Storage Interface (CSI) plugin provides high-performance shared storage for the Kubernetes clusters using the fast storage that is directly attached to the Kubernetes cluster nodes. InfoScale Storage provides highly available, persistent storage that conforms to CSI specifications for enterprise applications. It does so by using high-performance parallel storage access on shared storage (SAN) or in Flexible Storage Sharing (FSS) environments. InfoScale also supports Velero, which is a third-party application, to provide snapshot lifecycle management.
Application migration - InfoScale supports moving non-containerized applications into a container environment by copying the application data storage volumes onto the Kubernetes cluster nodes. The InfoScale CSI plugin then presents the same data to the applications that are running in the container.
The key benefits to using InfoScale with Kubernetes are:
High-performance parallel storage that provides better performance and reliability than NFS
Optimized resource utilization with the ability to use either existing SAN storage or the InfoScale advanced FSS option that provides better performance than SAN at a reduced cost
Migration of data from legacy to containerized MySQL applications
Support for in-depth application and infrastructure monitoring with the VCS application HA agents that run inside the containers or inside the sidecar container
Integrated I/O fencing and arbitration to protect against data corruption and to provide fast recovery in the event of a failure
Snapshot copies of the production data for analytics and disaster recovery
Volume cloning to address storage disk and node failures
Support for statefulset applications like MySQL
