Interoperability in the Cloud By Alex Espinoza aespinoza@structum.com.mx
Agenda • What is Cloud Computing? • Cloud Computing Categories. • Cloud Computing Types • Cloud Interoperability. • UCI • OCCI
What is Cloud Computing? • “Cloud computing is Internet- ("cloud-") based development and use of computer technology ("computing"). In concept, it is a paradigm shift whereby details are abstracted from the users who no longer need knowledge of, expertise in, or control over the technology infrastructure "in the cloud" that supports them.” http://en.wikipedia.org/wiki/Cloud_computing
Cloud Computing Categories • IaaS: Infrastructure as a Service (i.e. Amazon, Rackspace) • PaaS: Platform as a Service (i.e. MS Azure, Google Apps Engine) • SaaS: Software as a Service (i.e. SalesForce, Soho, Google Apps)
Cloud Computing Types • Public Cloud • Private Cloud • Hybrid Cloud; mixture of public and private cloud.
Cloud Interoperability • Avoid Vendor lock-in. • Take full advantage of the cloud as itself and not as a vendor infrastructure, platform or service. • An API about an API (One API to rule them all). • Develop you application once, deploy anywhere. • Enable hybrid clouds.
Cloud Interoperability Efforts: Why is it important? • UCI: Unified Cloud Interface by Cloud Computing Interoperability Forum (CCIF). • http://groups.google.com/group/unifiedcloud • OCCI: The Open Cloud Computing Interface by Open Grid Forum (OGF). • http://www.occi-wg.org/doku.php?id=spec
UCI • “The unified cloud interface (UCI) or cloud broker will be composed of a semantic specification and an ontology also referred to as "Semantic Cloud Abstraction". The ontology provides the actual model descriptions, while the specification defines the details for integration with other management models.“ http://groups.google.com/group/unifiedcloud
OCCI • “The Open Grid Forum Open Cloud Computing Interface (OCCI) working group will deliver an API specification for remote management of cloud computing infrastructure, allowing for the development of interoperable tools for common tasks including deployment, autonomic scaling and monitoring. “ http://www.occi-wg.org/doku.php
OCCI: Specification • Connection • Single OCCI REST end point over HTTP(S). • Authentication • SSL/TLS, NTLM or Kerberos • Representation • Open Cloud Computing Interface (OCCI) descriptor format. (application/occi+xml) • Open Virtualization Format (application/ovf+xml) • Open Virtualization Archive (application/x-ova) • Access to the Console.(VNC)
OCCI: Specification • Descriptors • Compute • Network • Storage • Identifiers • Resources identified by its URI.
OCCI: Operations • Create • POST • Retrieve • GET • Update • GET and PUT • Delete • DELETE • Requests • Trigger State Changes via POST
