MySQL NDB Cluster - Recommendations & Document

As deliverable we expect to receive a document with a small diagram of a recommended infrastructure for a Load Balanced MySQL NDB Cluster in 2 availability zones. The document must cover recommendations about: - infrastructure schema including the different availability zones, VMs needed for nodes, controls, etc, VPC, etc - Procedure to add and remove nodes without down time (for auto scaling) - Backup (procedure and versioning recommendations) - any other relative important information required to create the infrastructure maintenance procedures. We prefer the document to be delivered as a Google Drive Presnetation
