Implement Clustering in CloudHub

To ensure High Availability (HA), fault tolerance (FT), scaling, and performance for the application, a cluster can be set up in Mule which acts as a single unit to provide the mentioned capabilities. The instances in a cluster are called nodes that communicate and share a distributed memory grid. Mule uses an active-active model to cluster Mule Runtime engines.

The instances in a cluster are called nodes that communicate and share a distributed memory grid. Mule uses an active-active model to cluster Mule Runtime engines.

In case one node goes down, the other node will pick up failed nodes work.

In Active/Active model both the nodes (assuming cluster have two nodes only), are available to handle traffic and in case, one of them goes down, say node A, then the other one/node B will take over the load from its companion (the process is called failover) and when node A comes back up it will take back it's connections and services from node B (called failback) whereas in Active/Passive model only one server (primary node) handles all the traffic while the other node (secondary server) just sits there ready to take over if the primary node fails.

CIS offers a wide spectrum of cloud based computing services, including cloud integration solutions and cloud software solutions and integration services at cost effective price.

Cloud Data Integration combines cloud-based systems with on-premise systems creating a server-less engine with dynamic range and automation to simplify cloud-based processing.

Corey Quinn, cloud economist at The Duckbill Group, recently argued that multi-cloud is "the worst practice to be avoided by default”.The author of the Last Week in AWS newsletter defines multi-cloud as running the same workload across multiple cloud providers in an agnostic way.
