   You can horizontally scale most <%= vars.product_short %> components to multiple instances to achieve the redundancy required for high availability. 
   
  -You should also distribute the instances of multiply-scaled components across different AZs to minimize downtime during ongoing operation, product updates, and platform upgrades. If you use more than three AZs, ensure that you use an odd number of AZs.

  ### <a id='blobstore'></a> Blob Storage
  
  Blobs are large binary files. To store blobs for high availability, use external storage such as Amazon S3 or an S3-compatible service.

  ### <a id='resource-pools'></a> Resource Pools
  
  Each IaaS has different ways of limiting resource consumption for scaling VMs. Consult with your IaaS administrator to ensure additional VMs and related resources, like IPs and storage, are available to scale.
  
  To configure your resource pools according to the requirements of your deployment, see <%=vars.pools_link%>
