Suitable for production Arm64 Linux workloads when dependency checks and application benchmarks pass.

Why: Independent operators report production gains, but network limits, software compatibility and configuration affect the benefit. Graviton5 warrants a current price-performance comparison.
Next: Benchmark peak traffic, check Arm64 dependencies and PostgreSQL memory/kernel settings, compare total cost with Graviton5, then roll out in stages.

Constraints

Legacy AArch32 binaries require rebuilding or replacement.
Mixed Graviton generations need traffic allocation and autoscaling that account for their different capacity.
Network-bound services may realize smaller end-to-end latency gains than CPU benchmarks suggest.
Wide-vector cryptographic workloads can perform better on AVX512-equipped x86 instances.
High-concurrency PostgreSQL needs memory-page and kernel testing; a documented regression disappeared with huge pages enabled.
Cost savings can require resource tuning and node consolidation; a hardware-only upgrade can increase spend.
