Amazon Web Services The Blue Book pages 19 onwards References  http://developer.amazonwebservices.com/ connect/forumindex.jspa An overview of AWS   AWS is Amazon’s umbrella description of all of their web-based technology services. Mainly infrastructure services: ◦ ◦ ◦ ◦ ◦  Amazon Elastic Compute Cloud (EC2) Amazon Simple Storage Service (S3) Amazon Simple Queue Service (SQS) Amazon CloudFront Amazon SimpleDB Amazon EC2 is hiring ◦ http://aws.amazon.com/ec2-jobs/ Amazon EC2 EC2 provides web services API for provisioning, managing, and deprovioning virtual servers inside amazon cloud.  Applications anywhere on the Internet can launch a virtual server in the amazon cloud with a single web services call (either REST or SOAP WS call)  Where is SOAP API? For example,  http://docs.amazonwebservices.com/AmazonEC2/dg/2006-06-26/using-soap-api.html Storage Instance –store : disappears with the instance (transient)  Block storage: SAN-like, persists across time  S3 is independent of an instance: for archival purposes: vault: store it now and retrieve it at a later date  Amazon: SimpleDB: Relational database better than MySQl or Oracle for reliability.  Amazon Cloud-front Cloud-based content distributing network enables you to place the content at the edges of the network for rapid delivery.  Place the contents in S3 and run the application from anywhere and the content is moved to where the application is (to the edges).  S3 Amazon web services API support the ability to:  Find buckets and objects  Discover their meta data  Create new buckets  Upload new objects  Delete existing buckets and objects  When manipulating the buckets you can optionally specify where they should be stored.  Use REST API preferably something that abstracts out even that: Jets3t; s3cmd (command line)  BitTorrent access to S3 is also available  Bucket Naming Flat namespace  Names may contain only lowercase letters, numbers, periods, underscores, and dashes, and must start with a number or letter  Create your own namespace with your own bcukets  EC2 concepts See figure 2.1  Instance: virtual server running a guest os of your choice  AMI: Pristine image of your server so that you can launch any number of instance from this. Minimally machine image will operating systems + pre-installed tools.  Elastic IP address: Not static not dynamic but elastic; an IP reserved for your use; disappears once the server is terminated.  EC2 (contd.) Availability zone: Any two availability zones are guaranteed to share any common points of failure ( US, EU, Asia/Pacific)  Security group: define the firewall/security. Defines what can talk to your instances. (Ex; http, and not sftp etc.)  Snap shot: You can take snapshots of block volume (that can be formatted etc) and is stored in S3 for later use or for rollback etc.  What is the difference between instances and machine images?  How to access Ec2? AWS console http://console.aws.amazon.com  The ElasticFox firefox plugin  The amazon command line tool  Typical Use in an organization  Maintain a library of AMIs for the business ◦ May contain legacy systems or company-specific systems ◦ Harden AMIs using such software as Bastille  Launch instances for non-technical but domain experts to work with. ◦ What will you provide them so that they can start working?  Use S3 for archival storage and shared storage
