AWS is unique in the industry for their scale, pace of innovation and rich cross-platform support.Elastic Beanstalk release: July 2011.
•SOAP is deprecated over time as the services evolve.• SDKs are available for multiple languages (Java, Ruby, .NET, PHP). AWS toolkit.•Eventual consistency lets you scale much better than having hard transactions that are the enemy of scalability.•Architecture design guidelines: design for failure, consider eventual consistency, use async communications and stateless services.Example architecture will be analyzed later.
Amazon Elastic MapReduce uses a hosted Hadoop framework running on the web-scale infrastructure of EC2 and Amazon S3.
DynamoDB: instead of specifying instance type, RAM amount and storage capacity we specify the desired number of “read/write units” (1 query x 1 Kb x 1 second) and DynamoDB manages everything behind the scenes.
