Cloud Service Providers (CSPs) offer an ever-expanding array of instance types, ensuring that for any given workload there exists the perfect hosting option that matches the exact needs of that app or business service. But with this expansion comes an ever-increasing challenge to match the workloads to the offerings–there are many things to consider:
- Capacity: Total CPU, Memory, and I/O resources needed
- Ratio of resources: CPU optimized? Memory optimized?
- Workload pattern: Burstable? Horizontal elasticity?
- Storage: Local disk? EBR? NVMe?
- Hypervisor: Compatibility between generations
- Regional availability
- Volume commitments
