PAW Local Distributed is an upgrade to Planning Analytics Local Workspace that can be deployed in a container orchestration engine using either Docker Swarm by Docker or Kubernetes - an open source by Google, for high availability, fail-over, scalability, and fault tolerance in multiple application servers or virtual or even cloud machines.
Architecture:
The Planning Analytics Workspace Distributed is run on a Swarm mode by deploying the application on multiple Docker nodes (with unique node ids) also known as Swarm.
Docker Engine CLI could be used to create a swarm and deploy and manage the application services in swarm.
Swarm mode ensures secured connection across multiple servers. Additionally, some of the key features that Swarm mode offers includes:
Cluster management integrated with Docker Engine,
Declarative service model,
Desired state reconciliation,
Horizontal Scaling and Load Balancing,
Multi-host networking,
Automatic service discovery,
Service Discovery,
Rolling updates with roll-back
The Docker engine maintains high availability by effectively scheduling the failed node’s task to other nodes.
It was released in 2.0.41 version of Planning Analytics Workspace and is available to be downloaded from IBM Fix Centre from below link.
Note: The Docker Swarm is currently supported on Red Hat Enterprise Linux (RHEL) only.
