What is MuleSoft Clustering?
7
Clustering is a group of servers or mule runtime which acts as a single unit. Mulesoft Enterprise Edition
supports scalable clustering to provide high availability for mulesoft application.In simple terms, virtual
server composed of multiple nodes and they communicate and share information through distributed
shared memory grid.
By default, Mulesoft ensures the High availability of application if clustering implemented. Let's
consider the scenario one of the nodes in cluster crashed or goes down and under maintenance. In
such cases, mulesoft will ensure that request processed by other nodes in cluster.
Mulesoft clustering also ensures that request is load balanced between all the nodes in a cluster.
Clustering is only supported by on-premise mule runtime and it is not supported in Cloudhub.

Benefits Of Clustering?
8
● Clustering helps in improving application performance by dividing workload between nodes in
cluster.
● Horizontal Scaling can be done easily whenever required.
● Automatic coordination of access to resources, such as files, databases, and FTP sources.
● Automatic load balancing of processing within a cluster.
● Improve Performance, Automatic Failover, High Availability.

Clustering Types
10
There are 2 type of Clustering in MuleSoft
• Unicast
• Multicast
A unicast cluster requires that you configure the IP addresses of the nodes in the cluster. If a server
has multiple interfaces, use the internal IP address that allows the node to communicate directly with
other nodes. Clustering across different subnets is not supported.
A multicast cluster comprises servers that automatically detect each other. Servers that are part of a
multicast cluster must be on the same network segment.
One advantage of multicast clusters is that the server status doesn’t need to be Running to configure it
as a node in a cluster. Another is that you can add nodes to the cluster dynamically without restarting
the cluster.

11. All contents © MuleSoft Inc.
Prerequisite For Clustering
11
● Java 8 must be installed on your machine.
● Anypoint Platform Account.
● Mule runtime engine must be running on your machines.

12. All contents © MuleSoft Inc.
Server Group V/S Clustering
12
Server Group and Clustering both run in multiple distributed nodes. In server group, instances of
application is isolated from each other.
In clustering, nodes are aware of each other, share common information and synchronize status.
All the servers in server group and cluster must be running on same version of mule runtime.

13. Implementing Okta OAuth 2.0
With MuleSoft

14. All contents © MuleSoft Inc.
What Okta OAuth 2.0 OIDC?
14
OIDC (OpenID Connect) is an identity layer on the top of the OAuth 2.0 protocol. It allows clients to
verify the identity of the End User on the authentication performed by an Authorization Server as well
as provides basic profile information of End User in a secure way and Rest-like manner.

What is DevOps?
19
DevOps is a culture which promotes collaboration between Development and IT Operations Team to deploy code
to production faster in an automated & repeatable way.
Benefits of DevOps
- Releases/deployment can be done more frequently and quicker.
- Shorter mean time to repair.
- Cost Reduction and Reliable deployment.
- Fault Isolations.

20. All contents © MuleSoft Inc.
What is CI/CD?
20
Continuous Integration is development practice where developer checked in the code multiple times a day in
shared repository. Each integration is verified by automated build and automated unit testing.
Continuous Deployment is ability to move the changes including Features, Bug Fixes into the production quicker.
Benefits of CI/CD
- Quicker Releases
- Smaller Code Changes.
- Faster Mean Time To Resolution (MTTR).
- Improved Testability.
- Customer Satisfaction.

CI/CD Tools for Deploying Mulesoft Application
There are many tools available to achieve CI/CD pipeline. In today’s demonstration, we will walk through
below list of tools and they are widely used tools for achieving Devops for your Mulesoft
services/applications.
Tool Description
Github GitHub is a Git repository hosting service and provides a Web-based
graphical interface. It also provides access control and several
collaboration features, such as a wikis and basic task management
tools for every project
Git Git is the most commonly used version control system today and is
quickly becoming the standard for version control. Git is a distributed
version control system, meaning your local copy of code is a complete
version control repository.
MUnit MUnit is a Mule application testing framework which allows you to
build automated tests for your Mule integrations and API's. MUnit is
very well integrated with Anypoint Studio.
Nexus Nexus is a repository manager. It allows you to proxy, collect, and
manage your dependencies so that you are not constantly juggling a
collection of JARs
SonarQube SonarQube (formerly Sonar) is an open-source platform developed
by SonarSource for continuous inspection of code quality to perform
automatic reviews with static analysis of code to detect bugs, code
smells, and security vulnerabilities on 20+ programming languages.

MuleSoft MUnit Framework
MUnit is a Mule application testing framework which allows you to build automated tests for your Mule
integrations and API's. MUnit is very well integrated with Anypoint Studio.
MUnit Matchers
MUnit matchers are a set of DataWeave functions to define assertion conditions for any value in an
expression. When defining matchers, include the prefix MunitTools:: in the expression.
Matchers are grouped according to the type of conditions you want to validate.
Type Of Matchers
• Core Matchers
• String Matchers
• Comparable Matchers
• Iterable and Map Matchers

25. All contents © MuleSoft Inc.

Postman + Newman CLI
31
Postman is currently one of the most popular tools used in API testing. It started in 2012 as a side
project by Abhinav Asthana to simplify API workflow in testing and development. API stands for
Application Programming Interface which allows software applications to communicate with each
other via API calls.
A Postman Collection lets you group individual requests together. You can organize these requests into
folders.
Postman Tests are JavaScript codes added to requests that help you verify results such as successful or
failed status, comparison of expected results, etc. It usually starts with pm.test. It can be compared to
asserts, verify commands available in other tools.
