How to choose AWS instance type



  • We have desktop application written in Delphi and database SQLServer. We use testcomplete to test each release. now we are going to move those to AWS cloud.

    How do I select proper instance type?

    .....of course AWS site says m1 m3 for genaral M2 CR3 for memory intensive etc...but how much memory is memory intensive? testing application is graphic oriented but not as much as vidio processing.

    What factors should I consider when it comes to testing eco-system?



  • I would say it very much depends on your test purposes.

    If you want to test the performance of your application, then you need to define some SLO/SLIs with the help of your product people. Only then you would know on what type of machines, what should be expected.

    If it is a functional test, I go with a small instances to save money and if I see it is not enough, you can always easily use a better machine.
