AWS and Azure offer large number of options when it comes to chosing EC2 instance or VM's. As on date there are?400+ AWS EC2 instance types?to choose from.

As a Startup or Small business it is critical that you select the correct AWS EC2 instance or Azure VM. Else you end up incurring huge costs or face performance issues. Both impact business adversely.

How to choose the right EC2 instance type for your app, website or backend server ?

There two key variables. CPU and Memory. Still choosing the right combination from 400+ EC2 instances is confusing.

Challenges faced by Startups and Small businesses?in selecting the right AWS EC2 instance type are :

• Very little to no visibility about the load/usage pattern
• Actual resource utilized per user is not clear. Since user engagement with application is evolving.
• User base is scaling or not fixed
• Limited finances. Can’t afford to spend more than actual need

How does one go about selecting the right EC2 instance type or Azure VM???What is the approach for deciding the correct sizing ?

My answer may be a let down for you since I am not suggesting a super approach or some complex formula.

Yes, there are many permutations and combinations possible in CPU and Memory. Yes, there can be that ideal sized AWS EC2 instance type for your need. But you can figure it out only after many weeks or months of usage.

My simple suggestion is this.?Dont get too hooked up in choosing the right AWS EC2 instance for your app. Don’t spend too much time or efforts on it.

Go ahead and choose the AWS EC2 instance type you guess is closer to your requirement and budget. Start small.?The trick is?to monitor the chosen EC2 instance type from Day-1. This will ensure that you can take quick action if performance becomes an issue or costs are high. You can upgrade or downgrade as required pretty instantly.

Continue to monitor for few weeks and use that learning to?revise your selection?of EC2 instance type.If you need to know other ways to reduce AWS costs or resource wastages?check this out.
