    1. 1. Doug Tidwell – Cloud Computing Evangelist, IBM – [email_address] Keeping Your Options Open in the Cloud
    2. 2. Agenda <ul><li>Portability and interoperability </li></ul><ul><li>Life-alteringly exciting demo </li></ul><ul><li>Apache libcloud and The Simple Cloud API </li></ul><ul><li>Resources / Next steps </li></ul>
    3. 3. Portability and Interoperability
    4. 4. Vendor lock-in <ul><li>If there’s a new technology, any talented programmer will want to use it. </li></ul><ul><ul><li>Maybe the shiny new thing is appropriate for what we’re doing. </li></ul></ul><ul><ul><li>Maybe not. </li></ul></ul><ul><ul><li>We’re probably going to use it anyway. </li></ul></ul><ul><li>The challenge is to walk the line between using the newest, coolest thing and avoiding vendor lock-in. </li></ul>
    5. 5. <ul><li>In writing flexible code for the cloud, there are two key concepts: </li></ul><ul><ul><li>Portability is the ability to run components or systems written for one cloud provider in another cloud provider’s environment. </li></ul></ul><ul><ul><li>Interoperability is the ability to write one piece of code that works with multiple cloud providers, regardless of the differences between them. </li></ul></ul>Portability and Interoperability
    6. 6. How standards work <ul><li>For a standards effort to work, three things have to happen: </li></ul><ul><ul><li>The standard has to solve a common problem in an elegant way. </li></ul></ul><ul><ul><li>The standard has to be implemented consistently by vendors. </li></ul></ul><ul><ul><li>Users have to insist that the products they use implement the standard. </li></ul></ul>
    7. 7. Our Demo
    8. 8. A sample cloud application <ul><li>An order entry application running on one or many VMs in the cloud </li></ul><ul><ul><li>Creates a purchase order and sends it to a cloud-based queue for processing. </li></ul></ul><ul><li>A queue that holds the POs </li></ul><ul><li>An order processing application running on one or many VMs in the cloud </li></ul><ul><ul><li>Creates an invoice and stores it in the cloud </li></ul></ul><ul><li>Cloud-based storage that stores the invoices </li></ul>
    9. 9. Demo Architecture Order processing VM Cloud database Cloud queue Cloud storage Order processing VM 2. Create message with order ID 1. Create order details 4. Get order details 5. Store invoice 6. Delete message with order ID Single API to control VMs (start, stop, reboot) Single API for storage, queues, databases 3. Get message with order ID libcloud
    10. 10. A cloud-optimized application <ul><li>If we need more computing power to create orders, we fire up more VMs. </li></ul><ul><li>The queue of orders has unlimited capacity. </li></ul><ul><li>If we need more computing power to process orders, we fire up more VMs. </li></ul><ul><li>The storage for invoices has unlimited capacity. </li></ul><ul><li>When we don’t need VMs, we shut them down. </li></ul>
    11. 11. And now, the demo! <ul><li>Prepare to be astounded by the cloud in action! </li></ul><ul><ul><li>Due to cost constraints, we are unable to provide tissues for those moved to tears by the demonstration. </li></ul></ul><ul><ul><li>Persons prone to hyperventilation or motion sickness are advised to look away. </li></ul></ul><ul><ul><ul><li>Be advised the management cannot be held responsible for your medical expenses. </li></ul></ul></ul>
    12. 12. The message <ul><li>libcloud lets us control VMs from different vendors. </li></ul><ul><li>Simple Cloud lets us access storage and queue and database services in the cloud. </li></ul>
    13. 13. Apache libcloud & The Simple Cloud API incubator.apache.org/libcloud | simplecloud.org
    14. 14. Apache libcloud <ul><li>A common library for controlling VMs in the cloud </li></ul><ul><ul><li>Create, destroy, reboot and list instances, list and start images </li></ul></ul><ul><li>Supports dozens of cloud providers </li></ul><ul><ul><li>But you can add your own libraries to support other cloud providers. </li></ul></ul><ul><li>incubator.apache.org/libcloud </li></ul>
    15. 15. The Simple Cloud API <ul><li>A joint effort of Zend, GoGrid, IBM, Microsoft, Nirvanix and Rackspace </li></ul><ul><ul><li>But you can add your own libraries to support other cloud providers. </li></ul></ul><ul><li>A common library for IaaS services </li></ul><ul><li>There’s an article on the Simple Cloud API in the developerWorks Open Source zone: bit.ly/1bSkTx </li></ul><ul><li>simplecloud.org </li></ul>
    16. 16. The Simple Cloud API <ul><li>Covers three areas: </li></ul><ul><ul><li>File storage (S3, Nirvanix, Azure Blob Storage, Rackspace Cloud Files) </li></ul></ul><ul><ul><li>Document storage (SimpleDB, Azure Table Storage) </li></ul></ul><ul><ul><li>Simple queues (SQS, Azure Table Storage) </li></ul></ul><ul><li>Uses the Factory and Adapter design patterns </li></ul><ul><ul><li>A configuration file tells the Factory object which adapter to create. </li></ul></ul>
    17. 17. Openness in action <ul><li>IBM has contributed heavily to the Java implementations of libcloud: </li></ul><ul><ul><li>https://svn.apache.org/repos/asf/incubator/ libcloud/sandbox/java/trunk/ </li></ul></ul><ul><li>The Java implementation includes the basic framework plus adapters for the IBM Smart Business Cloud, Amazon and Rackspace. </li></ul><ul><li>Simple Cloud Storage adapters for S3 and Nirvanix are out now, more are on their way.... </li></ul>
    18. 18. Summary / Resources / Next steps
    19. 19. Get Involved! <ul><li>Download the code, build a prototype, submit requirements / new adapters / bug reports </li></ul><ul><ul><li>https://svn.apache.org/repos/asf/incubator/ libcloud/sandbox/java/trunk/ </li></ul></ul><ul><ul><li>simplecloud.org </li></ul></ul>
    20. 20. cloudusecases.org <ul><li>The Cloud Computing Use Cases group is focused on documenting customer requirements. </li></ul><ul><li>Covers Security, SLAs, and developer requirements. </li></ul><ul><ul><li>Available in Chinese, Japanese and Korean </li></ul></ul><ul><li>The group’s latest paper is Moving to the Cloud . </li></ul><ul><li>Join us! </li></ul>
    21. 21. developerWorks cloud zone <ul><li>Dozens of articles on cloud computing, including introductions, code samples, tutorials and podcasts. </li></ul><ul><li>ibm.com/developerworks/cloud </li></ul>
    22. 22. Summary <ul><li><hype> Cloud computing will be the biggest change to IT since the rise of the Web. </hype> </li></ul><ul><li>But to make the most of it, we have to keep things open. </li></ul><ul><li>And everybody has to get involved to make that happen. </li></ul>
