Since we're dealing with many vectors, we should iterate them if possible. Try to follow a process like this:
- Seek the input of major decision makers:
- VP and C-level executives involved with technology
- Product manager
- Application designers and architects
- Infrastructure team lead
- Find an amount of time that will satisfy most or all of the above.
- Follow the rest of the advice in this chapter to find a suitable architecture.
- Try to determine a rough cost for this and the closest alternative.
- Present one or more designs and cost estimates to decision makers.
- Document the final RPO decision and architecture as reference material.
