1 Enterprise SOA Strategy, Planning and Operations with Agile Techniques, Virtualization and Cloud Computing Presented by : Ajay Budhraja, Chief, Enterprise Services ME (Engg), MS (Mgmt), PMP, CICM, CSM, ECM (Master) AIIM, SOA(IBM), RUP (IBM), ITIL-F Copyright 2009 Ajay Budhraja for this entire presentation, All rights reserved 1

2 Enterprise Transition driven by Technology The current environment Build it Better, cheaper, faster Organizations need to constantly innovate to be competitive Shift from command and control to facilitate and enable Government needs to come up with innovative approaches to re-engineer business processes To accomplish great things, we must not only act, but also dream; not only plan, but also believe -Anatole France 2

3 The Transformation of Government Technology Change Drives Government Forward! Build Communities, Collaboration and Trust with Citizens and Users Transparent Collaborative Online Interactive Responsive Leverage Wikis, Blogs, Social networks, Mashups, Video tools for jobs, campaigns, fund raising, education, marketing etc. Utilize SOA, Agile, Virtualization, Cloud Computing effectively for Web 2.0 3

4 The Transformation to Enterprise SOA and Web 2.0 Command and Control Push Models Limited Interaction Individual Sites Silos Facilitate and Enable Pull Models High interaction Social media Enterprise Services 4

5 Enterprise Service Oriented Architecture Enterprise SOA is a blueprint for a flexible, open IT architecture and for developing services-based, enterprise level business solutions Enterprise SOA results in higher efficiency and reduced cost due to a higher degree of modularity and decoupling SOA promotes reuse, agility, adaptability, manageability, increases productivity 5

6 Enterprise Service Oriented Architecture SOA utilizes open standards to develop encapsulated building blocks SOA standardizes the interactions between the services Services are loosely coupled and modular elements Services promote reuse and interoperability 6

7 Enterprise SOA Benefits The development of an Enterprise Architecture Strategy and effective mapping of business processes to services using Agile, Virtualization and Cloud Computing facilitates the following: Cost savings Increased flexibility for redesign Reuse of business functionality Reduction of complexity, technology independence More efficient development 7

8 Enterprise Services Platform Cloud Cloud Cloud 8

9 SOA Evolution to Agile, Virtualization and Cloud Computing 9

10 Agile Myths 10

11 Agile Techniques Agile The ability to respond quickly to change leads to Better return on investment Better quality products Enhanced productivity Better team collaboration The implementation of Agile techniques results in greater effectiveness of handling changes in many areas such as: Requirements, Priorities, Technology, Tools, Resources 11

12 Agile SOA The objective is to rapidly adapt to changes in a cost effective manner. Key elements for service development are: Plan for each iteration as a comprehensive unit Identify and develop services iteratively Perform frequent and distinct service definition and integration Perform incremental service delivery Agile SOA Iteration #1 #1 Iteration #2 #2 Iteration #3 #3 Iteration #4 #4 12

13 Agile Service Framework Service Categorization Application Functional Business Functional logic Foundation Basic services Connector Link services Composite Aggregate services Independent Free standing Services Application Business Foundation Connector Composite Independent 13

14 Agile SOA Process Service requirements and analysis occur in parallel with service development SOA requirements do not have to be fully developed initially Develop potential services and refine the services during the SOA process Minimize iterations and incremental development for core and foundation services Develop plans for iterations and incremental development 14

15 Agile Service Management Agile Service Management can be based on the following: Evolutionary, Time based Incremental Change, collaboration Process adaptability PROJECT Increment Increment Iterations Iterations 15

16 The Evolution to Agile Linear Iterative Sequential Incremental Feedback at the end Continuous feedback 16

17 Agile approaches affecting productivity 1% 4% 22% 13% Much Lower Somewhat Lower No Change Somewhat Higher Much Higher 60% Results from Scott Ambler s Agile Adoption Survey 17

18 Virtualization Virtualization is an abstraction layer that decouples a consumer from the provider of resources. Hardware Virtualization Virtual Endpoints Virtualized Services Virtualization can result in : Improved workload management Infrastructure cost savings Effective utilization of resources Better support for consolidation and optimization Better Manageability, Operations and Security Virtualization enables shifting of workloads based on policies Virtualization complements SOA which abstracts functionality into services 18

19 Virtualization Virtualized Interfaces Integration, Deployment Virtualized Applications Virtualized Information Virtualized Infrastructure Governance, Management Security 19

20 Service Oriented Virtualization Service Oriented Virtualization can Decouple the dependency on deployed services and implementation layers to realize lower cost and agile implementation Publish and subsequently utilize virtual services on demand Facilitate Agile development, testing collaboration resulting in cost savings 20

21 SOA, SOI and Virtualization SOA Application functionality is developed into a service component layer Virtualization Abstract storage and systems into a service layer SOI Service Oriented Infrastructure Dynamic robust infrastructure that is virtualized, optimized, responsive 21

22 Cloud Computing Standardized, scalable, elastic capabilities delivered dynamically as services Information Technology capabilities are delivered as services Realization of SOA and Virtualization to develop a complete IT solution. Supported on dynamic infrastructure and can be on self managed platforms Cloud computing can result in Reduced cost Increased storage, automation Enhanced mobility and flexibility 22

23 Cloud computing End User Requests Mashup Interface Service Catalog Image Lifecycle Management Cloud Infrastructure &Application Provider User Request Management/Self Service Provisioning Security: Identity, Access, Integrity, Isolation, Audit & Compliance Applications & Services Service Management Service Lifecycle Management Performance Management Usage Accounting Virtualized Applications Availability/Backup/ Restore License Management Content & Data Web 2.0 Platform (image deployment, integrated security, workload mgmt., high-availability) Virtualized Infrastructure Virtual Resources & Aggregations Server Virt.

Standards Based Interfaces System Resources Virtualized Infrastructure SMP Servers Blades Storage Servers Storage Network Hardware Web 2.0 Solution Tools Design & Build Image Library (Store) Deployment Operational Lifecycle of Images Source: IBM 23

24 Cloud Services Processes and Applications as a Service Platform as a Service (Application Servers, Database servers) Infrastructure as a Service (Virtualized Servers, Storage, Networks) 24

25 SOA and Cloud Computing SOA creates loosely coupled, modular, that can leverage virtualization Cloud computing platforms can provide support for the deployment of services SOA complements and enables Cloud Computing SOA and cloud computing support a loosely coupled enterprise application infrastructure to develop manageable and flexible solutions 25

26 SOA supports Agile, Virtualization, Cloud Computing Loose coupling for services supports Agile responsiveness to change Abstraction of service interface from implementation enables dynamic change of service providers SOA Architecture supports extensibility for future needs Services can leverage virtualization and with Cloud computing third party services can be accessed Reuse based on services leads to agility and cost savings Agile, Virtualization and Cloud computing support the building, deployment and delivery of dynamic services 26

27 Enterprise SOA Strategy As part of the Enterprise SOA strategy: Establish SOA Governance, Methodology for SOA services and related practices Collaborate extensively with Business Owners, Business Analysts, SOA Architects, Architects Develop candidate architectures and reference models Develop services in a step by step manner, develop Service Level Agreements and measure the return 27

28 Enterprise SOA Strategy Establish a Vision that aligns Business with IT Define the SOA, Agile, Virtualization, Cloud Computing Roadmap and Plans Define the Organization structure Conduct detailed analysis of the business domain, functions, processes, interactions, events Define the SOA Architecture and Technology Develop services, aggregation of services 28

29 Enterprise SOA Planning Review current business processes, architecture Define future state and identify gaps Identify and classify services Develop Governance model, Benefits, ROI Develop detailed plan, task and cost estimates Develop Transition plan and communicate to the stakeholders 29

30 Enterprise Service Oriented Architecture Process Document Current State IT Assets, Business Flows Develop Future State Roadmap, Technology, Gap Analysis Develop Strategy and Plan Project plan, resources, priorities Document Transition Plan Plan to move from Current to Future State 30

31 SOA Technology Execution Create a SOA roadmap and detailed plans Incorporate the SOA strategy in transition planning Define mechanisms for discovering services Categorize Services - Business Service, Application Services, Infrastructure Services Develop Agile services with the proper granularity Manage and monitor service usage, performance, reliability Abstract cross cutting functionality such as infrastructure functions Create a Service registry and publish the services to this registry Comply with industry standards SOAP, XML, WSDL, WS-Security, BPEL Leverage process and methodology to build SOA solutions and utilize SOA Implementation frameworks and Service Mediation and Orchestration Leverage Enterprise Service Bus for a standards based, secure, reliable messaging mechanism Deploy services using virtualization, cloud computing as needed 31

32 SOA Execution Framework Presentation Services Presentation Services SOA Management Business Services Services Components Services Composite Services API s Components Databases, Applications Databases Applications 32
