ARM64 In The Cloud: Graviton, Ampere, And Cost-Performance Tradeoffs

Why hyperscalers ship Arm servers, what software must rebuild, and when to benchmark migrations.

Cloud providers offer **ARM64** instances (AWS Graviton, Azure Ampere Altra, Google Tau T2A) with competitive price-performance for many Linux workloads. CPUs use AArch64 instruction sets distinct from x86_64.

Interpreted languages (Node, Python, Go) often run with aarch64 builds of runtimes. Native dependencies (encryption, image processing, database engines) must supply arm64 binaries or be compiled from source in CI.

Benchmark before migrating production: cryptographic libraries, SIMD-heavy media workloads, and legacy x86-only containers block naive lift-and-shift.

Multi-arch **Docker** images (`buildx --platform linux/amd64,linux/arm64`) simplify hybrid fleets. Pin base images per architecture in Kubernetes node pools with taints and tolerations.
