- 2. 2 Growth of AWS AWS “Simple Queue Service” fosters ‘decoupled’ service oriented architecture message passing • “Developers can move data between distributed components of their applications that perform different tasks, without loosing messages or requiring each component to be always available” S3 Storage, EC2 Compute, ELB Load Balancing, RDS Relational Database, SimpleDB Amazon S3 Growth 1.3 Trillion in 2013 DynanoDB 201 2 200 6

- 15. 15 SQS, S3 and EC2 Use Case Scalability with new EC2 instances to meet heavy load demands • Failure isolation and adaptation
- 16. 16 SQS, S3 and EC2 Use Case Can you think of a use case extension for scaling or decoupling? • Pipeline processing to ‘decouple’ longer-running operations in a separate, dedicated server
- 17. 17 AWS Execution Environment Virtualization Layer Compute Storage Server Public AMIs Private AMIs Paid AMIs · Elastic IP address · Elastic Block Store Amazon Machine Image Create an AMI Create Key Pair Configure Firewall Launch Private AMI: Images created by you, which are private by default; you can grant access to other users to launch your private images Public AMI: Images created by users and released to the community, so anyone can launch instances based on them and use them any way they like Paid AMI: You can create images providing specific functions that can be launched by anyone willing to pay you per each hour of usage on top of AWS charges
- 19. 19 AWS Access Credentials Credential type you use depends on the type of AWS API • Access Keys To make secure REST or Query protocol requests to any AWS service API Parts and Usage Access Key ID—Your Access Key ID identifies you as the party responsible for service requests; you include it in each request, so it's not a secret Secret Access Key—Each Access Key ID has a Secret Access Key associated with it; This key is used to calculate the digital signature that you include in the request; Your Secret Access Key is a secret, and only you and AWS should have it • X.509 Certificates To make secure SOAP protocol requests to AWS service APIs Parts and Usage X.509 Certificate – holds the public key and related metadata; You include it in each service request, so it's not a secret Private Key—Each certificate has a private key associated with it; Use the private key to calculate the digital signature to include in the request; Your private key is a secret, and only you should have it and AWS doesn't keep a copy • Key Pairs To launch and then securely access your Amazon EC2 instances You can make as many as you like by giving friendly names (can’t replace any particular key pair) Private key that you keep with you; Public key that AWS keeps to allow access
- 20. 20 Cost Saving Considerations in AWS On-Demand Instances • Pay for compute capacity by the hour with no long- term commitments Reserved Instances • Make a low, one-time payment for each instance you want to reserve and in turn receive a significant discount on the hourly charge for that instance Spot Instances • Bid on unused EC2 capacity and run those instances for as long as their bid exceeds the current Spot Price
