Agenda

• What Cloud computing is• What Cloud computing best fits• What Service Oriented Architecture is• How SOA Fits the Cloud• (and how viceversa)• A SOA platform that fits the cloud


What Cloud Computing is

• Rent the physical infrastructure• Consume resources as a service and pay only for resources that

they use. • Improve utilization rates, as servers are not unnecessarily left idle

(which can reduce costs).– Not 1 application : 1 group of servers– Yes n modules : m virtual machines

• Reliability is improved since multiple redundant sites are used.• Scalability via dynamic ("on-demand") provisioning of resources,

without users having to engineer for peak loads. • Security could loss of control over certain sensitive data, and the lack

of security for stored kernels.


What Cloud Computing fits with

Cloud features Application expected features

N modules : M virtual machines Highly modular

Multiple redundant sites Location independent

Rent physical infrastructureSecurity could loss of control

Highly secure

Dynamic provisioning of resources Monitorable

Multiple redundant sites Easily manageable


What Service Oriented Architecture is

• Service-oriented architecture (SOA) is a – flexible set of design principles – used during the phases of systems development and integration in

computing.

• A system based on a SOA will – package functionality as a suite of interoperable services– that can be used within multiple separate systems from several

business domains.

• (MUCH more than only a technology shift)



• SOA Reference Architecture



• Key factors:1. From Business to IT

2. From Silos to an Information System

3. Service Lifecycle

4. Service Portfolio Management

5. SOA Governance

3. SOA Service Lifecycle


4. Service Portfolio Management

• Catalogs all the information of the services• With a workflow manages the service lifecycles steps (aka ALM),

validating their evolution – rfp, development, production, phase out


5. SOA Governance

What SOA demands to Cloud

• Expose all the Cloud management features as API• Expose all the Cloud KPI / monitoring features as API• that can be called by the SOA Management features

• Provide proper customizable billing schemas (think at the business)


Is this new?


What’s new

• The difference between the past distributed solutions:– From the Cloud point of view, it’s the cloud itself

• rent the physical infrastructure

• pay only for resources that they use

• multiple redundant sites

• scalability via dynamic ("on-demand") provisioning of resources

– From the SOA point of view• the economic saving of having an Information System:

• the costs are at the business function usage from HW to SW
