  1. Cloud Computing at GES DISC Presented by: Long Pham Contributors: Aijun Chen, Bruce Vollmer, Ed Esfandiari and Mike Theobald GES DISC UWG May 11, 2011

  2. What is Cloud Computing? • Computing where services and storage are on-demand and provided by the internet (the cloud) • Three basic types of cloud computing • Software as a Service (SaaS) - traditional applications through the web browser with no client to install; most widely use service i.e. Gmail, Yahoo • Platform as a Service (PaaS) - virtualized servers on which users can run existing applications without the worries of OS, CPU load balancing, etc. i.e. Microsoft Azure, Google App Engine, Rackspace • Infrastructure as a Service (IaaS) - using clusters, servers, storages and networks as a service to provide a whole data center i.e. Amazon's Elastic Compute Cloud (EC2), NASA Nebula Cloud SaaS PaaS IaaS

  3. Cloud Prototype Objectives • Generate and prototype an application using NASA Nebula IaaS • Test the system demand for our current applications • Understand the effort behind cloud computing • How to setup an instance… • Understand Nebula’s capabilities… • Pros and cons • Evaluate Nebula cloud versus other cost saving solution

  4. Nebula Cloud Prototype Status • Currently, the status of Nebula Cloud Prototype includes: • Ported S4PM into Nebula instance and tested S4PM samples • AIRS PREPQC (AIRS simple algorithm) installed and tested in Nebula • Installed and tested AIRS L2 PGE in the cloud • Preliminary comparison of AIRS PGE in the cloud against local AIRS PGE

  5. Preliminary Result (Two-day AIRS L1 data processing)

  6. Nebula Cloud Prototype Status • Upcoming implementation includes: • Install and test AIRS L1 algorithm • ChainAIRS L1 and L2 • Collect I/O, speed and disk utilization metrics • Determine cost model (cloud vs. in-house HW) • Utilize Nebula Object Store to allow larger and faster cloud storage (still waiting from Nebula developers) • Giovanni 4 prototype in the cloud • Documenting results
