How Cheap is AWS Graviton2 ? 20% or 40% or 50% or 60%!
It has been more than 3.5 years since Graviton2 went GA(General Availability). However, there are still more insights to uncover regarding the cost-effectiveness of Graviton2 compared to x86. Graviton is widely marketed as 20% cheap from pure price perspective and upto 40% cheap when seeing from price-performance perspective. But for some regions graviton2 is insanely cheap, and for some workloads it can be upto 60% cheap. This post is an attempt to uncover those insights.
For all below scenarios only pure cost savings are considered excluding the performance benefits. Since the performance benefits are not guaranteed for all workloads.
While most regions you could save 20% by migrating to graviton, ap-south-1 and ap-south-2 you could saving almost 50% by migrating from x86 to graviton. And this is purely the cost savings excluding the performance benefits but those performance benefits are not guaranteed for all workloads so at minimum you would easily save 50% in costs and the workloads that get performance benefits can save another 10% i.e 60% in total costs reduction.
As seen from above graph, if you move from x86 to graviton in ap-south-1, you can save more than 50% in costs, while most of the other regions it's in the range of 20-25%.
