Who is using EC2: A sample <ul><li>Justin.TV </li></ul><ul><ul><li>3,500 simultaneous video streams with 1Gbps of b/w </li></ul></ul><ul><li>Slideshare </li></ul><ul><li>Powerset </li></ul><ul><ul><li>NLP Search Engine, 100s of instances for content analysis </li></ul></ul><ul><li>Dozens of Facebook applications </li></ul><ul><li>Probably your startup for application prototyping </li></ul>

EC2: Virtual Instance <ul><li>Virtual Machine as a single instance having </li></ul><ul><ul><li>1.7GHz x86 Processor </li></ul></ul><ul><ul><li>1.5 GB RAM </li></ul></ul><ul><ul><li>160 GB Local Disk </li></ul></ul><ul><li>Powered by Xen </li></ul><ul><ul><li>Layers multiple VMs on top actual hardware </li></ul></ul>

EC2: Gotchas <ul><li>Instances are ephemeral </li></ul><ul><ul><li>All data is lost if you shutdown </li></ul></ul><ul><li>160 GB of local disk </li></ul><ul><ul><li>Not suitable for big databases </li></ul></ul><ul><ul><li>S3 is not natively mounted </li></ul></ul><ul><li>No Native image of Windows </li></ul><ul><ul><li>Community has hacked it though </li></ul></ul>

Future Directions <ul><li>Amazon working on enhancements </li></ul><ul><ul><li>Persistence </li></ul></ul><ul><ul><li>Support for large databases </li></ul></ul><ul><ul><li>Windows native images </li></ul></ul>
