class=\"wp-block-heading\">What is Graviton?<\/h3>\n\n\n\n<p>Graviton is a family of Arm-based processors used in cloud virtual machines. Not publicly stated details vary by provider releases.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Do I need to recompile my application?<\/h3>\n\n\n\n<p>If you use native binaries, yes. For interpreted languages and containers built from multi-arch images, sometimes no.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Will all workloads be cheaper on Graviton?<\/h3>\n\n\n\n<p>Varies \/ depends. Benchmarks determine cost-effectiveness per workload.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do I validate parity before rolling out?<\/h3>\n\n\n\n<p>Run functional tests, perf benchmarks, and canary deployments with SLOs and automated rollback.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does migration affect security posture?<\/h3>\n\n\n\n<p>It can. Ensure scanners and agents support arm and re-run vulnerability scans.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I run Graviton in my existing Kubernetes cluster?<\/h3>\n\n\n\n<p>Yes if your scheduler and node pools support mixed architectures; careful nodeSelector and image multi-arch support required.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What about third-party binaries and vendors?<\/h3>\n\n\n\n<p>Many vendors provide arm builds but some do not; engage vendors early.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do I measure cost benefits?<\/h3>\n\n\n\n<p>Use cost per request metrics normalized by traffic and include storage\/network costs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Are observability agents compatible?<\/h3>\n\n\n\n<p>Most major vendors provide arm builds by 2026; verify agent compatibility before migration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How long does a migration take?<\/h3>\n\n\n\n<p>Varies \/ depends on number of services, dependencies, and organizational capacity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Should I use emulation in CI?<\/h3>\n\n\n\n<p>Emulation is useful for early validation but not sufficient for performance testing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to handle stateful services?<\/h3>\n\n\n\n<p>Prefer read replicas or separate testing clusters and plan state migration steps carefully.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What SLOs should I set during canary?<\/h3>\n\n\n\n<p>Conservative SLOs aligned with existing baselines; protect error budget tightly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is Graviton suitable for ML workloads?<\/h3>\n\n\n\n<p>Certain CPU-bound inference tasks can benefit; GPU-heavy training will not.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What are common performance regressions?<\/h3>\n\n\n\n<p>FP heavy workloads, crypto libraries, and JIT paths can regress without tuning.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do I avoid alert noise?<\/h3>\n\n\n\n<p>Group alerts, use suppression windows during planned experiments, and set contextual thresholds.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When should I rollback automatically?<\/h3>\n\n\n\n<p>When canary consumes predefined error budget thresholds or SLOs breach on user impact metrics.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Who owns the migration?<\/h3>\n\n\n\n<p>Platform team for tooling and service teams for per-service validation and rollout.<\/p>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>Graviton migration is an operational and engineering program that requires investment in tooling, testing, observability, and cross-team collaboration. When done methodically with SLO-driven canaries, CI multi-arch builds, and robust telemetry, it can yield cost and performance benefits. However, pitfalls around native dependencies, monitoring gaps, and performance regressions mean teams must proceed conservatively and iterate.<\/p>\n\n\n\n<p>Next 7 days plan (5 bullets)<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Day 1: Inventory top 10 candidate services and list native dependencies.<\/li>\n<li>Day 2: Add multi-arch builds for one service and run basic tests.<\/li>\n<li>Day 3: Provision arm staging nodes and validate observability agents.<\/li>\n<li>Day 4: Run performance benchmarks and capture baselines.<\/li>\n<li>Day 5: Execute a controlled canary with automated rollback and collect SLI data.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Appendix \u2014 Graviton migration Keyword Cluster (SEO)<\/h2>\n\n\n\n<p>Primary keywords<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Graviton migration<\/li>\n<li>Graviton migration guide<\/li>\n<li>Arm migration cloud<\/li>\n<li>migrate to Graviton<\/li>\n<li>Graviton instances<\/li>\n<\/ul>\n\n\n\n<p>Secondary keywords<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Arm64 migration<\/li>\n<li>multi-arch CI<\/li>\n<li>Graviton performance<\/li>\n<li>Graviton cost savings<\/li>\n<li>Graviton best practices<\/li>\n<\/ul>\n\n\n\n<p>Long-tail questions<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>How to migrate services to Graviton instances<\/li>\n<li>What breaks when migrating to Graviton<\/li>\n<li>Graviton migration checklist for SREs<\/li>\n<li>How to benchmark Graviton vs x86<\/li>\n<li>How to build multi-arch Docker images for Graviton<\/li>\n<li>Can my JVM app run on Graviton<\/li>\n<li>How to run observability agents on Graviton<\/li>\n<li>How to handle native dependencies for Graviton<\/li>\n<li>How to design canary rollouts for Graviton migration<\/li>\n<li>How to measure cost per request after Graviton migration<\/li>\n<li>Is Graviton good for ML inference<\/li>\n<li>How to automate rollbacks during Graviton canary<\/li>\n<li>How to ensure security scanning for arm images<\/li>\n<li>How to set SLOs for Graviton migration canaries<\/li>\n<li>How to validate database replicas on Graviton<\/li>\n<li>How to test serverless functions on Graviton runtimes<\/li>\n<li>How to avoid observability blind spots during Graviton migration<\/li>\n<li>How to choose Graviton instance family<\/li>\n<li>How to migrate Kubernetes nodes to Graviton<\/li>\n<li>What are common Graviton migration failures<\/li>\n<\/ul>\n\n\n\n<p>Related terminology<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Arm64<\/li>\n<li>AArch64<\/li>\n<li>multi-arch image<\/li>\n<li>buildx<\/li>\n<li>QEMU emulation<\/li>\n<li>canary deployment<\/li>\n<li>blue green deployment<\/li>\n<li>SLI SLO error budget<\/li>\n<li>observability agents<\/li>\n<li>CI runners<\/li>\n<li>pod affinity<\/li>\n<li>nodeSelector<\/li>\n<li>EBS optimization<\/li>\n<li>telemetry schema<\/li>\n<li>container manifest<\/li>\n<li>SBOM<\/li>\n<li>security scanner arm support<\/li>\n<li>cost per request metric<\/li>\n<li>benchmark harness<\/li>\n<li>latency p95<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>&#8212;<\/p>\n","protected":false},"author":7,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[],"tags":[],"class_list":["post-2129","post","type-post","status-publish","format-standard","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.3 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>What is Graviton migration?
