Unisys Service Oriented Self Adaptive Systems

  1. 1. Service Oriented Self Adaptive Systems – Marrying SOA and Cloud Computing Kartik Mecheri Unisys Federal Systems Washington DC October 2009
  2. 2. Introduction – Set the Context • Service: • software component (module) that is made available publicly • Broker/Distributor: • a directory for finding services • Consumer: • uses the functionality provided by the services (c) 2009 Unisys Confidential Page 2 2
  3. 3. Service Oriented Self Adaptive Systems (SOSAS) What is SOSAS? System that changes its capabilities at runtime utilizing the principles of SOA • SOSAS enables and • SOSAS will help address supports the following challenges – Evolution through adaptation – Dynamic Composition and – Open adaptive systems QoS aware Service Coordination capabilities – Closed adaptive systems – Dynamically reconfigurable – Pervasive contexts runtime architectures • Self-* (healing, adaptive, etc.) – End-to-end security solutions – Optimal Service Discovery and Selection (c) 2009 Unisys Confidential Page 3 3
  4. 4. Characteristics of Cloud Computing NIST defines Five key characteristics for cloud: • On-demand self-service • Ubiquitous network access • Location independent resource pooling • Rapid elasticity • Pay per use How does SOSAS help achieve these characteristics? (c) 2009 Unisys Confidential Page 4 4
  5. 5. Envisioning the Future in Federal • Meeting the QoS attributes in a Distributed Cloud environment- Inter-cloud dependencies? • Open Architecture and Open Standards are more critical • Converting business policies to IT policies • Migration from one Cloud Provider to another – Domain-centric standards becomes more critical • Built in security – Addressing privacy issues and FISMA compliance • Open source software becomes more relevant (c) 2009 Unisys Confidential Page 5 5
  6. 6. SOSAS and Cloud Providers • Hybrid Cloud for mission support • Establish Cloud standards for interoperability • Cloud interoperability can be achieved by following open standards • Development and Test environment into public cloud • provisioning and de-provisioning through self-adaptation • Self adaptation best achieved through principles of service oriented computing • Security certification must be standardized at a lower level of granularity Provider must deploy cloud offerings based on SOSAS (c) 2009 Unisys Confidential Page 6 6
