USolutions - SOA and the Cloud

SOA in a Cloud http://www.ubiquitous-solutions.com

SOA in a Nutshell 06/07/09 Ubiquitous Solutions © 2009 “ SOA is a design paradigm focused upon the creation of logical units of code that can be shared and reused over standard protocols.” Benefits of SOA are:

Facilitates reuse of software assets.

Enables creation of composite services and BPMS solutions

Technology bridge between different software platforms.

Focus shifts from applications to common business services.

Facilitates creation of distributed solutions that can be

easily run in the cloud.

Service contract . A defined schema that identifies the message structure, and operations and endpoints.

Loose-coupling . Consumers of the service shouldn’t be aware of any implementation details. Related to this is service abstraction , which aims to make the service a “black-box” to the consumer.

Statelessness . Ideally, a service is completely stand-alone, and does not require previous or follow-up calls for processing. This dramatically improves scalability.

Discoverability . A service registry should exist that identifies available services and their contracts.

SOA Technology Profile – JBoss Rules 06/07/09 Ubiquitous Solutions © 2008 Create, manage and deploy complex business rules without hard-coding them into applications. Subject matter experts, not developers, perform rule authoring! Wizard-Driven Rule Authoring Navigating Rule Assets Deployment

SOA Technology Profile – ESP 06/07/09 Ubiquitous Solutions © 2009 Esper is an open-source Event Stream Processor (ESP). With it, you analyze inbound event streams for patterns, which can be used to identify abnormal/unexpected behavior (forthcoming release of JBoss Rules will also include such functionality). These event streams can be generated by service components, so that your SOA environment can be managed effectively in real-time. Note : ESP is sometimes referred to as Complex Event Processing (CEP).

SOA Technology Profile – ESB 06/07/09 An Enterprise Service Bus (ESB) is the swiss-army knife for integration services. It can mediate messages, perform transformations & routing, and SOA-enable legacy applications. Many solid open source ESBs exist.

Cloud Computing 06/07/09 Ubiquitous Solutions © 2009 “ Cloud computing is Internet based development and use of computer technology, whereby dynamically scalable virtualised resources are provided “as a service” over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure ("in the cloud") that supports them.” According to Wikipedia… Benefits of Cloud Computing are…

Greatly Reduces Cost. No servers or data center to maintain.

Increased Flexibility & Agility. Add capacity as-needed (“elasticity”).

Reliability. Greater redundancy, world-class infrastructure.

Frees up Internal Resources. Focus on differentiation.

Promotes ability to quickly try/discard technologies.

Cloud Computing & SOA… 06/07/09 Ubiquitous Solutions © 2009 A perfect marriage! Service virtualization means that the actual physical endpoint of the service is unknown to the consuming client, which in this case could be a BPM process, web application etc. The service mediator intercepts and redirects call to the proper location. Virtualized services run in the cloud.

Services for the Cloud… 06/07/09 Ubiquitous Solutions © 2009 Requires collaboration between IT & Business Successful SOA requires a close collaboration between subject matter experts and development. When aligned, the results are a flexible, adaptive and responsive IT.
