Hi Peter
you could move an entire grid to AWS in one fell swoop if you wanted (i.e. a switch over/parallels run typically are seen ) the approach obviously depends on things like appetite for risk and the cost profile and if it makes sense.
High Level thoughts:
- use the opportunity to refactor storage and high TCO items on the infrastructure side, this often equates to benefits
- use it as an opportunity to refactor any major pinch-points.
- don't assume your users are happy, see if there are any easy wins, too often i hear the phrase lift and shift...on its own it only a very short sighted.
- contact your account team, we can giev lots advice on doing this we have design patterns and tools to help on the journey
- use our audit tool to work out what assets you need to move https://communities.sas.com/t5/SAS-Communities-Library/Preparing-for-promotion-migration-and-modernization-of-your-SAS/ta-p/687375 has soem useful hints
- look at Viya, it will give you cloud native capabilities (inc access to low cost native AWS storage) and the flexibility of elastic compute which will be great for smoothing workloads.
