I will migrate your AWS workloads to graviton and cut your compute bill

Paying too much for x86 on AWS? Graviton instances usually cost less for the same work, but moving a live system scares people. I have moved about 2,500 instances to Graviton in clusters, across Apache, Java (including a real-time bidding server), MongoDB, ScyllaDB, MySQL, Kafka, Druid, Prometheus, Jenkins and Python services.

How I do it: I first check what will and will not run on ARM (binaries, container images, native libraries), then migrate one node at a time behind the load balancer or inside the cluster, test it, and roll the rest in only when it behaves. I keep an AMI of the old node so rollback is quick. Where the service is clustered there is no downtime. Where it is a single server, I agree a short planned window with you first.

You get a compatibility report, the migration done, a before/after cost estimate from your own instance types, and a short runbook with rollback steps.

I do not rewrite application code. If something will not run on ARM, I tell you and leave it on x86.
