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

slide3

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
slide4

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
slide5

Preliminary Result

(Two-day AIRS L1 data processing)

slide6

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
