Mule Clustering

Mule clustering allows multiple Mule instances to act as a single unit. A cluster shares data through distributed memory across nodes, which can reside on the same or different machines. The document demonstrates setting up a two-node Mule cluster on the same machine by running two standalone Mule servers and registering them with a cluster manager. Key steps include starting the servers, viewing them in the server tab, creating a new cluster called Anirban_Cluster, adding both nodes to the cluster, and verifying the cluster is formed with both nodes listed.
Mule Clustering
- 1. Mule Clustering on same Machine By Vijay
- 2. Before we procced, we will take a look on what a Cluster is. A cluster can be said as a set of Mule instances that acts as a unit. We can also say that, a cluster is a virtual server composed of multiple nodes and a servers in a cluster communicate and share information through a distributed shared memory grid. This means that the data is replicated across memory in different physical machines. Reference :- https://docs.mulesoft.com/mule-user-guide/v/3.6/mule- high-availability-ha-clusters
- 3. Mule server has the ability to form cluster for High Availability. To setup a cluster on a same machine we need to have multiple mule standalone server in the machine. Let’s consider we have two nodes or we can say two standalone server present in the same machine.
- 15. So, we can see mule agent now registering node2 in the list.
- 16. So, under Server tab we can see both the nodes listed as below :-
- 17. We will now click on Add menu at the top and then select New Custer menu
- 18. We will give the name of the cluster say Anirban_Cluster in our case, and then add both the nodes under it and click Add button :-
- 19. After, waiting for a while we can see our cluster has been created :-
- 20. On clicking on the cluster Anirban_Cluster we can see, both the nodes :- node1 and node2 listed there as follows:-
- 21. Here it was a small demonstration of creating Clusters of node residing on same machine. This process can be used to create Clusters that may includes multiple nodes residing on same machine or different. And we can add as many nodes we like under a cluster but yes the cluster can have a maximum of 8 nodes and all the nodes should be up and running during adding a node into cluster. So at the end I can only say that, let’s spread our knowledge and expand our Mule community.
