AWS Amazon webservices

Last week i took a short look on the AWS cloud system, basically because there was a free 12 month offer (750 hours a month). There are just a few types supported by this offer, so i created a "micro" machine.

You can choose between different operating systems, such as RedHat , Centos an one of amazones own distribution (Amazon Linux AMI 2013.09.2), which basically is another "fork" of RedHat/Centos.

So starting with documentation, i always like documentation and there are some really good whitepapers around, you can find them here. I guess you also should take a look at the overview whitepaper which is here.
Amazon pushed a lot of services into their cloud, like many different databases (mongoDB, DynamoDB, MySQL) and load balancers. The system is full scalable, so there is no need to buy a huge infrastructure, you can scale it to your needs. The paying is based on the amount of resources you need.

Currently there are two promos running

  • one promo where amazon and Intel are giving you 600 hrs compute time
  • and a basic 720hrs and 12 months free usage here

AWS comes around with some really nice features, for example security, so when you create anew instance you _must_ create a public key to login, and be sure to save it you cant access it twice.

Lets talk about Amazon Linux AMI

  • kernel 3.4.73-64.112.amzn1.x86_64
  • you can use yum 
  • nginx is available in 1.4.3 release 1.14.amzn1
  • mysql in version 5.5.34
As it seems selinux is available but not installed by default. I dont know if this is good or bad. You can use the micro instance within the 720hrs free offer.

So lets try it!
