A crucial part of a successful migration is collecting business and technical requirements, allowing you to properly design a cloud platform. For guidance, review Preparing for VMware Cloud on AWS before beginning your requirements gathering.
Business requirements are an important part of the requirements gathering process. Input examples include:
-
RTO/RPO targets
-
Business SLAs for the applications workloads based on SQL Server databases
-
Licensing considerations
-
Security and data-management considerations
Technical requirements will directly influence logical design and should be collected and validated with care. Pay special attention to the following bullet points:
-
Performance requirements of the workload (e.g., transactions-per-second, number of user connections, expected future workloads changes)
-
Capacity requirements (e.g., future growth, other projects to be served)
-
Manageability requirements (e.g., providing access to a SDDC to appropriate user groups, reconfiguring monitoring tools, backup solution in use, modifying scripting, vRealize Operations workflows)
-
Scalability requirements (e.g., method for increasing capacity of a SDDC, scale-out versus scale-in approach)
-
Availability requirements (e.g., SQL Server high-availability solutions in use, DRS groups, host-isolation response, number of availability zones required)
-
Application requirements (e.g., type of workloads [e.g., OLTP/data warehouse], dependencies between on-premises components and network flow between them)
