AWS services cost optimizing

A couple of weeks ago I decided to test how it fills with Sybase Unwired platform and so I went for SUP SDK with AWS account. As you can see SAP creates SUP instance on m1.large box and frankly with its 4 processing units and almost 8Gb of RAM it’s more than enough for testing and playing around purposes. Moreover, I left my instance working for a few days and was frustrated with the monthly bill from amazon.

Actually you can change instance type when it is stopped. Go to your AWS console, select your instance, stop it, then change its type – there is a command in the Actions menu:

I tested all instance types starting from t1.micro (which is free of charge) and it turns out that the working solution would be m1.medium – it is quite responsive and costs half of t1.large. And yes – don’t forget to stop the instance when you don’t need it running.

      good to know. Costs is always important issue.

      Bear in mind that there are T&Cs on the free tier usage. For example, you can run a Linux micro instance AND a Windows micro instance for the month for free, but your second Linux (or Windows) one will cost, even if you only have two in total.

      Also bear in mind the size of the images; you won't get an SAP system on them 😆 - while they may be useful as a very simple web-host or a jump box for a VPN, you can't even (reliably) run the latest minecraft server on it !!

      Thanks Martin. Yes, I tried t1.micro and honestly its performance is unbearable with SUP 2.2 installed, so I gave up in favor of m1.medium. If you start it only when you need it then the bill looks quite affordable.
