  Key Concepts: 
  A cache group is a collection of virtual machines (VMs) that are managed by the Virtual Machine Container (VMC) component of SAP. It is used to store and manage the VMs that are used to run SAP applications. The cache group is responsible for managing the resources that are allocated to each VM, as well as providing a secure environment for the VMs to run in. 
  
  How to use it: 
  The cache group is used to manage the resources that are allocated to each VM. It also provides a secure environment for the VMs to run in. To create a cache group, you must first create a VMC instance and then add the VMs that you want to be part of the cache group. Once the VMs have been added, you can configure the resources that will be allocated to each VM. 
  
  Tips & Tricks: 
  When creating a cache group, it is important to ensure that the resources allocated to each VM are sufficient for its needs. If the resources are not sufficient, then performance may suffer. Additionally, it is important to ensure that the security settings of the cache group are configured correctly, as this will help protect the VMs from malicious attacks.
