● Moving to AWS Graviton is a smart move because it can save businesses a lot of money, which is important for companies that want to spend less on their cloud services. The special Graviton computers not only cost less than the regular ones but also do a great job without slowing down. This is super important because, in the cloud, you often pay for what you use, so using fewer resources is a big deal. The Graviton computer is like a money-saver superhero!

● One amazing thing about the Graviton computer is that it’s good at using energy efficiently, which means it costs way less to keep it running. This is especially helpful for apps that need much power to run, where costs can be a big worry. Plus, the Graviton computer doesn’t just save energy; it’s also priced well compared to other computers you can find on AWS.

● Just to give you an idea, imagine a table that shows how much money you can save by using r6g instances with Graviton2 processors instead of r6a and r6i instances with regular x86 processors. It’s like getting a better deal while still getting top-notch performance.

Examples:

Certainly, let’s break down the example with a table to illustrate better the cost savings achieved through migrating from an x86-based instance to a Graviton-based instance:

In this example:

● x86-based Instance (c5.large):

   – Cost per Hour: $0.085

   – Monthly Compute Hours: 1000 hours

   – Monthly Cost: 1000 hours * $0.085/hour = $85

● Graviton-based Instance (c6g.large):

   – Cost per Hour: $0.068

   – Monthly Compute Hours: 1000 hours

   – Monthly Cost: 1000 hours * $0.068/hour = $68

By migrating the workload from the x86-based instance to the Graviton-based instance, the monthly cost decreases from $85 to $68. This represents a cost reduction of $17 per month, corresponding to a significant 20% decrease in computing costs. This example clearly illustrates the tangible financial benefits of adopting Graviton-based instances for businesses seeking to optimize their cloud expenditures without compromising on performance.
