Functional scope

Interoperability within the context of Cloud Computing means enabling the Cloud Computing Ecosystem whereby individuals and organizations are able to widely adopt Cloud Computing technology and related services in such a fashion that multiple Cloud platforms can exchange information in a unified manor and ultimately work together seamlessly.Examples of such interoperability are e.g. solutions running on multiple disparate Cloud instances and use of resources in other heterogeneous Cloud instances.To realize this desired Interoperability, standards are required at all levels, e.g. infrastructure, platform, application, service, data and management.

What is Interoperability?

The ability of IT systems, as well as the business processes they support, to exchange data and enable the sharing of information and knowledge – UK Govt definitionInteroperability means enabling the Cloud ecosystem so that multiple cloud platforms can exchange informationInteroperability means being able to seamlessly exchange data at different layers between cloud service providersInteroperability is the capability of two systems understanding each others’ intents in exchange of communicationsInteroperability is an enabler for interchangeability (replacement of one element with another)Interoperability is the goal of standards but standards do not guarantee interoperabilityYou can achieve interoperability without standards


What is Interoperability (2)

Interoperability is an enabler for portability (at some level interoperability is portability)• Portability refers to the ability to port the layer above• PaaS portability is needed when moving apps

Interoperability refers to provisioning within the layer itself – SaaS-to-SaaS interoperability occurs between appsWhy is interoperability different in a cloud ecosystem compared to normal software development?Motivations for interoperability:• 1. To increase customer choice, competition and innovation• 2. To allow more players in the market

Policy Objectives (background information)

Right to move applications between Cloud providersRight to port data (quickly) between Cloud providersRight of user to own their dataKeep overhead of certification and compliance to a minimumApply open access/open source policies that allow extension of APIs and specsDemand side: Interoperability between Cloud services from different providers to prevent vendor lock-inOpen and flexible market to provide choice for consumersTransparency and technology neutrality


Requirements for Interoperability

Between cloud providersBetween public and private cloudsConsumers to cloud providersInteroperability as a basis for a competitive market in servicesExtensibility to enable new servicesSaaS focus on domain specificsGeneric solution across verticalsCommon taxonomy as a basis for interoperabilityInteroperability between and across devicesNeed to consider legacy


Use Cases (1)

User of one Cloud accessing storage in another Cloud (to provide elastic storage)Applications and services running on (and communicating between) heterogeneous cloud platformsApplication using resources (CPU, storage) in another heterogeneous cloud platform (resource bursting)Resource sharing across different time zonesDemonstration of data portability (across Service Providers)What is needed to transfer a running STATEFULL service from Cloud Provider A to B?• Moving a file sharing service between Cloud providers• Moving a streaming service between Cloud providers


Use Cases (2)

B2B (or Govt) procurement from Buyer Cloud vs. Supplier CloudEnd customer (SME) going through broker (IT Provider) to CloudMove of on-premise server to/from public, private or hybrid CloudMulti-operator or multi-service provider conferencingDemonstration of need for integration/federation of CloudsDemonstration of use of Trans-National / Trans-Regional CloudsVM Govt (G-Cloud) – universal service for Govt staff

APIs

OpenStackCloudStackOCCIDo we need a standardised IaaS API to remove the jungle of APIs?• Should we adopt / upgrade an OS API such as OpenStack?

Interoperability of the user interface:• APIs used to inject data• APIs used to extract results

3 levels:• “Right to use” API• “Right to implement” API• “Right to change” API


Content

Access to content on different cloudsInteroperability of DRMs
