 What are Amazon Web services (AWS) ?  What’s cool when developing with AWS ?  Architecture of AWS  Quota & Pricing  Amazon Web Services  Demo application  Deploying Simple Applications

 Simple Storage Service (S3) ◦ Provides limitless storage of large files in the cloud  Elastic Compute Cloud (EC2) ◦ Provides virtual machine instances called Amazon Machine Instances ◦ Ability to create AMI’s on the fly according to demand  Simple Queue Service (SQS) ◦ Provides reliable messaging between any applications using AWS  Amazon EBS  Amazon Cloud Front ◦ Think of this as a simple web server for static content  Amazon SimpleDB, and others …

 Services are provided over Web  Communication is web-service based  Communication interface API has been designed to be simple and effective  Three kinds of interfaces: REST, Query & SOAP based  Authentication embedded in each message

Standard On-Demand Instances Small (Default)$0.090 per Hour$0.115 per Hour Medium$0.180 per Hour$0.230 per Hour Large$0.360 per Hour$0.460 per Hour Extra Large$0.720 per Hour$0.920 per Hour

 Ability to increase or decrease capacity within minutes  Ability to commission one, hundreds, or even thousands of server instances simultaneously  A web service API to control the scaling of instances depending on your needs  A “pay only for what you use” pricing model

 Highly available and highly reliable storage volumes ◦ From 1GB to 1TB ◦ Mounted as devices by EC2 instances  Use them as hard drives  Created in specific availability zone  Automatically replicated  Performance metrics (Amazon CloudWatch)  $0.10 per 1 million I/O requests you make to your volume

 Backups of your data lying in Amazon S3  Incremental  Loaded lazily  Shared

 Provides reliable messaging between any applications using AWS  Multiple writers and readers ◦ Multiple parts of your system can send or receive messages at the same time  Configurable properties and access control  Messages are stored in distributed environment ◦ To facilitate reliable delivery

 Web service that makes it easy to set up, operate, and scale a relational database in the AWS cloud ◦ Currently supporting Oracle and MySQL  Simple to deploy  Scalable & reliable  Secure

 Stores textual information in a simple database structure  Does not mandate schema for database  Indexes information to facilitate faster query  Stores data securely and reliably across multiple data centers  No limits on amount of data

 Offers secure online storage system for any kind of data  Data is universally accessible over the Web  No limits on amount of data, longevity or bandwith for transfer or publish  Scalable, distributed system ◦ Stores data redundantly across geographically separated data centers

 A relational database service with minimal administration ? ( Amazon RDS )  A fast, highly scalable NoSQL database service ? ( Amazon DynamoDB )  A NoSQL database service for smaller datasets ? ( Amazon SimpleDB )  A relational database you can manage on your own ( Amazon EC2 + Amazon EBS )

 Easy setup, operate and send notifications from the cloud !  Highly scalable, flexible, cost-effective  Broad protocol choice (HTTP, , SMS, etc.)  Best for event-driven workflows  “Pull” mechanism

 Authoritative Domain Name System (DNS) service  Well documented and easy to setup

 Web service for content delivery (CDN)  Supports edge locations  Map domain name to distribution  Fast, simple, elastic, reliable, global and cost-effective

 Supports Adobe’s Flash and Windows Media Services  Benefits to end users – close; easy to pause, rewind; different encodings  Wide variety of formats

 Hosting your most frequently accessed website components  Distributing software  Publishing popular media files

 The problem with databases ?  Memcached solution  Implements Memory Caching system by caching repetitive queries  Easy to setup, manage, scale  Each cluster has one or more cache nodes
