Amazon Web Services (AWS)

Regions and Availability Zones

Amazon cloud computing resources are hosted in multiple locations world-wide. These locations are composed of AWS Regions and Availability Zones. Each AWS Region is a separate geographic area. Each AWS Region has multiple, isolated locations known as Availability Zones. An Availability Zone is a logical data center in a region available for use by any AWS customer. Each zone in a region has redundant and separate power, networking and connectivity to reduce the likelihood of two zones failing simultaneously. A common misconception is that a single zone equals a single data center.

Web Services

Amazon Elastic Compute Cloud (Amazon EC2)

• Instance: Instances marked with a t are used for testing, the m (memory-intensive) types can be used for processing larger databases or installing single servers. The large capacity c (CPU-intensive) Instances are recommended for e.g. hosting Magento stores.
  • Amazon Machine Image (AMI)
    • Instance Types
      • t2.micro (free)

Key Pairs

• are generated, private key (*.pem file) has to be downloaded (which is only be possible once, because it is not stored by AWS) and used for connecting to the server
• PuTTY doesn't natively support the private key format (.pem) generated by Amazon EC2. You must convert your private key into a .ppk file before you can connect to your instance using PuTTY. You can use the PuTTYgen tool for this conversion.

Amazon RDS

• create, manage and scale an Amazon Relational Database Service like MySQL
