OGF29 – Cloud Standards Interoperability Demo

OCCI, CDMI & OpenNebulaChicago, June 20-22, 2010

Agenda

1. Intro – Krishna Sankar2. CDMI – Mark Carlson3. CDMI iPad Client Demo – Rich Ramos4. OCCI – Thijs Metch5. JavaFX Client Demo – David Moolenaar

Cloud Interoperability

• Always on the top on everybody’s mind – Just after security, compliance & control

• This demo is a first step• Not how well the bears dance, but the fact that they

could dance !• CDMI/OCCI working across the storage and compute

clouds– CDMI Storage primitives (incl allocation, access, rules,

policies, constraints …)– OCCI – CSP interface

CDMI iPad Client: Goals

1. Primarily Instructional on CDMI 2. Not General Purpose “Cloud Storage” Client3. Show Network Interactions4. Show Object Information5. Provide CDMI Object Library (future)

What is OCCI?

• Open Cloud Computing Interface– Becoming OGF proposed standard

• OCCI provides features to identify, link and categorize “dumb RESTful resources”

• OCCI-infrastructure defines kinds, actions, & attributes to work with virtual machines

CDMI in Cloud Computing

12

A single cloud computing infrastructure can implement both the OCCI and CDMI interfaces

The infrastructure abstracts the configuration of the networking and virtual machine details and uses the standard interface merely to define connectivity

A cloud computing client can then utilize the interfaces to both specify the data requirements and then use that data for guests

OpenNebulaOpen-Source Toolkit for Building Cloud Infrastructures• Open Source Created and Supported at the University of Madrid under Dr. Rubén S. Montero &

Dr. Ignacio M. Llorente. CDMI Integration Provided by Gary.Mazzaferro @AlloyCloud .com

• Orchestrates storage, network and virtualization technologies to enable the dynamic placement of multi-tier services on distributed infrastructures, combining both data center resources and remote cloud resources, according to allocation policies

• Provides internal and Cloud administration and user interfaces for the full management of the IaaS Cloud platform

• Private Cloud: Management of virtual infrastructure in the data-center or cluster

• Hybrid Cloud : Combination of private with Cloud resources

• Public Cloud: Cloud interfaces for the full management of services

The ClientA Standards Based Cloud Client

Used JavaFXDeveloped by R2AD, LLCSponsored by DISA CTO

cloud.r2ad.net

Client Requirements• Simple/Small

– Implement use-case (first with simple get/put)– Keep UI footprint small – potential phone app– UI became more sophisticated with experience

Client Interactions• Required to communicate with OCCI + CDMI

– Clear specifications and examples very helpful– Used local test server to code up initial GET/PUT– Use case driven (keeping goals on target)

JavaFX Client Demo

Client Lesson Learned• Code for network not being reliable

– Let user cancel requests. Timeouts.– Use local cache or persistence?

• Use of remote admin tools helpful– ssh terminal, vSphere admin console– Virtual Desktop Interface (VDI)

• Teleclient Solution w/Sun Secure Global Desktop or VNC

• Virtual Machines for servers helpful– Snapshots, transportability, etc.

• Way Ahead:– Make code more efficient (reduce server calls, parsing)– More integration with OCCI/CDMI – more features. security– Looking for feedback and chance to develop more
