Instance Types & Sizing

Part of the Cloud Computing Roadmap.

Summary

Cloud providers offer many VM sizes and families optimized for different workloads — general purpose, compute-optimized, memory-optimized — choosing correctly avoids both under-provisioning and wasted spend.

How to Learn This

  • 1Compare 3 instance types from different families and note their CPU/memory ratios.
  • 2Learn to match a workload type (web server, database, batch job) to an appropriate instance family.
  • 3Practice right-sizing a hypothetical workload rather than defaulting to 'the biggest one to be safe'.
