 # Overview 
 
-RabbitMQ is a robust and flexible open-source message broker software that facilitates communication between distributed applications. It implements the Advanced Message Queuing Protocol (AMQP) standard, ensuring reliable messaging across various platforms and languages. With its support for multiple messaging protocols and delivery patterns, RabbitMQ enables seamless integration and scalability for modern microservices architectures. It provides features such as message persistence, clustering, and high availability, making it a preferred choice for handling asynchronous communication and decoupling components in enterprise systems.

It implements the Advanced Message Queuing Protocol (AMQP) standard, ensuring reliable messaging across various platforms and languages. With its support for multiple messaging protocols (MQTT, STOMP etc.) and delivery patterns (Fanout, Direct, Exchange etc.), RabbitMQ enables seamless integration and scalability for modern microservices architectures. It provides features such as message persistence, clustering, and high availability, making it a preferred choice for handling asynchronous communication and decoupling components in enterprise systems.

+# RabbitMQ Compute Resource Autoscaling
+
+This guide will give an overview on how KubeDB Autoscaler operator autoscales the database compute resources i.e. cpu and memory using `RabbitMQautoscaler` crd.
+
+## Before You Begin
+
+- You should be familiar with the following `KubeDB` concepts:
+  - [RabbitMQ](/docs/guides/RabbitMQ/concepts/RabbitMQ.md)
+  - [RabbitMQAutoscaler](/docs/guides/RabbitMQ/concepts/autoscaler.md)
+  - [RabbitMQOpsRequest](/docs/guides/RabbitMQ/concepts/opsrequest.md)
+
+## How Compute Autoscaling Works
+
+The following diagram shows how KubeDB Autoscaler operator autoscales the resources of `RabbitMQ` database components. Open the image in a new tab to see the enlarged version.
+
+<figure align="center">
+  <img alt="Compute Auto Scaling process of RabbitMQ" src="/docs/images/RabbitMQ/compute-process.svg">
+<figcaption align="center">Fig: Compute Auto Scaling process of RabbitMQ</figcaption>
+</figure>
+
+The Auto Scaling process consists of the following steps:
+
+1. At first, a user creates a `RabbitMQ` Custom Resource Object (CRO).
+
+2. `KubeDB` Provisioner  operator watches the `RabbitMQ` CRO.
+
+3. When the operator finds a `RabbitMQ` CRO, it creates required number of `StatefulSets` and related necessary stuff like secrets, services, etc.
+
+4. Then, in order to set up autoscaling of the various components (ie. ReplicaSet, Shard, ConfigServer, Mongos, etc.) of the `RabbitMQ` database the user creates a `RabbitMQAutoscaler` CRO with desired configuration.
+
+5. `KubeDB` Autoscaler operator watches the `RabbitMQAutoscaler` CRO.
+
+6. `KubeDB` Autoscaler operator generates recommendation using the modified version of kubernetes [official recommender](https://github.com/kubernetes/autoscaler/tree/master/vertical-pod-autoscaler/pkg/recommender) for different components of the database, as specified in the `RabbitMQAutoscaler` CRO.
+
+7. If the generated recommendation doesn't match the current resources of the database, then `KubeDB` Autoscaler operator creates a `RabbitMQOpsRequest` CRO to scale the database to match the recommendation generated.
+
+8. `KubeDB` Ops-manager operator watches the `RabbitMQOpsRequest` CRO.
+
+9. Then the `KubeDB` Ops-manager operator will scale the database component vertically as specified on the `RabbitMQOpsRequest` CRO.
+
+In the next docs, we are going to show a step by step guide on Autoscaling of various RabbitMQ database components using `RabbitMQAutoscaler` CRD.
