Time Change event Business process change IT synchronize change Business objective Time Time to agility and business benefits What they have What they want Business objective Lag!

Enterprise Application Traits (today): 

Enterprise Application Traits (today) Big, monolithic and expensive Not designed for reuse as services Inter application is hard – so many standards Synchronous (RPC) DCE, DCOM, CORBA, Java RMI, CICS DPL, RDBMS stored procedures Asynchrnous (Messaging) Tuxedo ATMI, MQSeries, Java JMS, CICS TDQs, TIBCO Difficult to change due to tight integration Proprietary and difficult to integrate Suited to a vendor-specific platform Developed and enhanced over many years – they become entrenched, legacy. Technology carries too much weight in business decisions

Abstract for Agility : 

Abstract for Agility 2. Loosely-coupled, open interfaces User Interface Client Hardware & OS 1. Tightly-coupled, proprietary interfaces 3. Driven by the Web application platform Database Application Web Platform Active Adaptability

CIO balancing act—SOA drivers: 

CIO balancing act —SOA drivers Mitigate risk: Ensure security, continuity of business operations Reduce impact of technology implementation on people and process Enable regulatory compliance Maximize return: Lower costs of maintaining heterogeneous environment Reduce complexity Reduce cost of change Improve performance: Improve IT’s ability to respond to changing business needs Improve customer satisfaction Link and extend value chain Increase agility: Drive higher levels of reuse Improve response to business demands Enable business to respond to changing markets and competitive pressures

SOA is not new! Why has it been difficult to date?: 

SOA is not new! Why has it been difficult to date? Unfortunately most applications lacked the modularity to present functions as services Programmer’s meet schedules with tightly integrated code, undermining services architecture Integration & Reuse is inherently difficult Different developers Different places Different schedules Different data sources Different models

In The News Recently (Oct. 2005): 

In The News Recently (Oct. 2005) Linda Price, GM of IT for Fairfax “Ultimately, what I want to produce is an IT strategy that will enable us to respond with agility and flexibility to what’s happening in the market - and at the moment, in our market, there’s likely to be substantial change. The business could be called upon to re-invent itself,” Ian Graham, CIO at Macquarie Bank Hired to lead the transformation of the 700-strong IT department into a service-oriented, customer-focused group. Michelle Tredenick NAB CIO (on integrating CRM) But, with disasters such as the aborted Integrated Systems Implementation project and the massive write-down fresh in its memory, the NAB has taken a big broom to its IT strategy, promising a new era that ties technology projects tightly to the business and is devoid of "big bang" initiatives. NAB has also introduced new governance for projects, which involves improving the skills of project managers, setting up a steering committee to approve investments and killing projects where required. "Our underlying core banking systems are actually quite adequate,“ "They are quite robust. But what has happened over the years is that there have been lots of functions added to them and lots of pieces of business functionality that have been put in there that probably belong in different parts of the architecture. For the NAB, flexibility means speedier development of new products and shorter turnaround times for products such as loans. "That's what we think will really hit the bottom line,"

Slide11: 

Is an architectural style that provides a framework through which organizations describe services and their behaviour The change from an object-oriented system to a service-oriented one is an evolutionary idea stemming from the Internet and Web system SOA is an approach to enterprise architecture that abstracts IT functionality into business-oriented Services. Service-Oriented Architecture Is the evolution of [Web] applications into service- oriented components with Web Services. Services are at the centre of a SOA “SOA Governance: Reengineering IT Governance ZapFlash”, By Jason Bloomberg, ZapThink, Document ID: ZAPFLASH-10272004

Key Elements of a SOA*: 

Approved Products, Technologies, and Facilities Web Services Platform *Understanding SOA with Web Services by Eric Newcomer and Greg Lomow, Addison Wesley 2005. Key Elements of a SOA*

SOA – Centred on Services: 

SOA – Centred on Services Services are: Simple Abstract Platform independent Service description Identification, Interface, Behaviour It does not describe implementation ―> promotes loose-coupling Get me the order status The order status is… Service Consumer Service Provider

A service may have many operations: 

A service may have many operations New customer order Check order status Update order status Split order

Service composition: 

Service composition Services may be created through composition. We can combine existing services to compose new ones. SOA Principle Send message to customer Get customer preference Validate preferred channel Send message

Process: 

Process Process is a fundamental part of SOA A business process can be used to link together services to create new functionality. SOA Principle Send message to customer Get customer preference Validate preferred channel Send message

Process: 

Process The business process then offers a service. Get customer preference Validate preferred channel Send message Send message to customer

Process: 

Process This process-based service can, in turn, be used in other services. Customer preferences service Channel management service Comm. service Send message to customer Send invoice to customer Customer invoice service

Services may be shared: 

Services may be shared SOA Principle Re-use ~ Sharing A result of loose-coupling is that services may be easily shared or re-used. For example: Tax calculation Customer data management Geographical locator Customer preferences service Channel management service Comm. service Send message to customer Send invoice to customer Customer invoice service

Service Publication/Discovery: 

Service Publication/Discovery Services are placed in an enterprise service registry for publication. The service registry holds service description information. There are multiple (security controlled) views onto the service registry. SOA Principle Export Services Internal Services Business Services Infra- structure Services Service Registry

Dynamic service selection: 

Dynamic service selection Services may be selected at any time. A service consumer may discover a service it needs according to a set of criteria Price Availability Quality Speed Etc. Service brokers may assist Map upload service Resolve at run-time All the world $0.50 United States $0.05 Western Europe $0.40 SOA Principle

SOA shifts the way we think: 

SOA shifts the way we think

When not to use SOA?: 

When not to use SOA? Standardized platforms and technology Rate of change is low Tight-coupling Visibility requirements are met/low Real-time performance is critical Increased business agility Greater capability visibility Improved interoperability Reduced cost of integration Maximized re-use Simplification Performance overhead Increased design effort Cost of change Contra-Indications

More In The News (Oct 2005): 

More In The News (Oct 2005) Australian Customs – Integrated Cargo System (Cargo system backdown, Simon Hayes OCTOBER 25, 2005) The web-based Customs Interactive System was inadequate for larger brokers Brokers said the government had not paid enough attention to small brokers and forwarders. "We don't want to use the web system -- it's too slow," "We want to get the messages back through our system." "Often it's not the technology that's the problem, it's the processes or the people“

Summary: SOA Core Principles: 

Summary: SOA Core Principles A service has a description Identification, Interface, Behavior Abstraction Loose-coupling Services may have operations Services may be composed Process uses services and may implement a service Sharing Re-use Publication Discovery Classification Dynamic service selection SOA is an architectural approach, centered around the concept of services

SOA Technology and Web Services: 

SOA Technology and Web Services One of the key reasons for the today’s focus upon SOA is the emergence of supporting technologies. SOA is an architectural approach, centered around the concept of services SOA ≠ Web Services SOA can exist without Web Services Web Services can be utilized without an SOA Using web services can significantly enhance our ability to implement SOA A common source of confusion

Web Services: Where are we?: 

Web Services: Where are we? What is a Web Service? Based on well defined industry standards Promotes loose-coupled connectivity Can be synchronous or asynchronous Is platform agnostic and Vendor Independent Java, .NET, LAMP, home-grown Provide integration at service level Connectivity defined by www.WS-I.org

Base Web Service Standards *(aka First Generation Web Services):

Extended Web Service Standards: 

Extended Web Service Standards Web Services Distributed Management OASIS WSDM definition: “define web services management, including using web services architecture and technology to manage distributed resources. This Technical Committee will also develop the model of a web service as a manageable resource” WSDM compliant Web Services and platforms will offer a standard WSM interface Management Of Web Services (MOWS) Management Using Web Services (MUWS) Reliability and Messaging

Extended Web Service Standards: 

Extended Web Service Standards Security WS-Security – provides message-level security on an end-to-end basis for Web Services messages XML Encryption – provides confidentiality using a variety of encryption algorithms, ensuring reception of unchanged messages XML Signature – using a variety of encryption and signature mechanisms, ensures messages are not tampered with and are received once and only once

Extended Web Service Standards: 

Extended Web Service Standards Metadata XML Schema – message typing and structuring WSDL – associates messages and exchange patterns with service names and network addresses WS-MetadataExchange – queries and discovers metadata associated with Web Service. Can also fetch a WSDL file and the associated WS-Policy definition WS-Policy – Associating QoS requirements with WSDL definition. WS-Policy includes declarations for security, transactions and reliability

Extended Web Service Standards: 

Extended Web Service Standards Messaging SOAP - Simple Object Access Protocol Provides the definition of the XML-based information which can be used for exchanging structured and typed information between peers in a decentralized, distributed environment WS-Addressing – enables messaging systems to support message transmission in a transport-neutral manner through networks that include processing nodes such as endpoint managers, firewalls, and gateways WS-Reliability – designed to ensure reliable delivery of SOAP messages using unreliable transports such as HTTP WS-Coordination - Describes an extensible framework for providing protocols that coordinate the actions of distributed applications

Extended Web Service Standards: 

Extended Web Service Standards Web Services Orchestration WS-Choreography Business or other activities that involve multiple different organizations or independent processes that use Web service technology to exchange information Long running business processes should also be transactional Hours or days rather than sub-second intervals May cross organizational boundaries Supply chain and service aggregation scenarios Locking is neither desirable or feasible We need alternative techniques Start Check Process three Process four Finish Process one Process two Asynchronous, could take weeks! Call to external entity Company might go out of business!

Extended Web Service Standards: 

Extended Web Service Standards Transactions WS-Composite Application Framework (WS-CAF) Web Service Context (WS-CTX), a lightweight framework for simple context management Web Service Coordination Framework (WS-CF), a sharable mechanism to manage context augmentation and lifecycle, and guarantee message delivery Web Services Transaction Management (WS-TXM), comprising three distinct protocols for interoperability across multiple transaction managers and supporting multiple transaction models two phase commit long running actions business process flows Start Txn Process one Process two Commit Txn

Extended Web Service Standards: 

Extended Web Service Standards Transactions WS-AtomicTransaction (WS-AT) The coordinator accepts: Commit Upon receipt of this notification, the coordinator knows that the participant has completed application processing and that it should attempt to commit the transaction. Rollback Upon receipt of this notification, the coordinator knows that the participant has terminated application processing and that it should abort the transaction. The initiator accepts: Committed Upon receipt of this notification, the initiator knows that the coordinator reached a decision to commit. Aborted Upon receipt of this notification, the initiator knows that the coordinator reached a decision to abort.

Extended Web Service Standards: 

Extended Web Service Standards World’s first Web Service transaction platform (HP-WST) released in 2002 by HP and Arjuna Technologies Ltd. Formed in 2002 from Hewlett Packard Middleware Division Long history in reliable distributed systems Leading research in reliable distributed systems since 1985

Too Many Web Service Standards?: 

Too Many Web Service Standards? SCSI USB TCP/IP BIOS Sockets and plugs TV and radio Mobile phone Fiber optic X-Ray CD player Amplifier Loudspeaker … Lots of standards that we never even think of… They just ‘work’!

Web Services: Why will they succeed?: 

Web Services: Why will they succeed? Universal Support All vendors participating in standards work; interoperability defined by the WS-Interoperability consortium Protocol not Platform All WS define protocols, not platform or implementation Low Product Costs WS basic needs will be supported ‘for free’ as part of a platform or add-on to existing product; WS are not expensive to implement Evolutionary WS can be used to leverage existing infrastructure rather than ‘rip and replace’. “If it’s not broken, don’t fix it!” Business Oriented WS address business needs and can be understood by the business person as well as the technologist. Especially true when WS are being exposed externally as ‘business functions’

What does Google say?*: 

What does Google say?* What applications can I create using Google™ Web APIs? Some possibilities might include: Issuing regularly scheduled search requests to monitor the Web for new information on a subject. Performing market research by analyzing differences in the amount of information available on different subjects over time. Searching via non-HTML interfaces, such as the command line, pagers, or visualization applications. Creating innovative games that play with information on the Web. * From the Google™ Web APIs FAQ http://www.google.com/apis/index.html

Web Services Integration Toolkit: 

Web Services Integration Toolkit Succeeds HP BridgeWorks on Alpha and Integrity Is a set of integration tools based on Open Source tools and standards Is focused on integration at the API-level Calls routines written in 3GL languages, e.g., ‘C’, COBOL, BASIC, FORTRAN or ACMS Tasks From Java, Microsoft .NET, Web Services Deployment descriptor specifies where 3GL routine to be run: In-process, i.e., in the same process as Web application container Out-of-process, i.e., in a separate OpenVMS process managed by the WSIT runtime

WSIT vs Bridgeworks: 

WSIT vs Bridgeworks Consider WSIT as the next generation of Bridgeworks

Web Services Integration Toolkit: 

Web Services Integration Toolkit Steps to follow: Prepare 3GL module using WSIT toolkit, e.g., Remove terminal I/O; ensure can be linked as a shareable image May be necessary to write a wrapper for the old code Write a client to test the new interface Determine whether in-process or out-of-process

Web Services Integration Toolkit: 

Web Services Integration Toolkit Create XML IDL file (on Integrity) using OBJ2IDL for 3GL or STDL2IDL for ACMS Validate XML IDL file using VALIDATE Generate components using IDL2CODE Call generated JavaBean using technology of choice, e.g., Apache Axis, Apache Tomcat, BEA WebLogic Server, ‘P’ language, etc.

Web Services Integration Toolkit: 

Web Services Integration Toolkit Two types of deployment: 1. In-process deployment occurs when the application and the client are called from the same process Pros: Fastest return time for client calls to application. No overhead added by the WSIT runtime Cons: A crash will bring down all components in the process (client and application server together with all other threads)

Web Services Integration Toolkit: 

Web Services Integration Toolkit Two types of deployment: 2. Out-of-process deployment occurs when the client and application are run in different processes Pros: Typically scales better than in-process deployments. Allows the use of the WSIT runtime deployment properties Cons: Adds complexity and overhead to every call

Web Services Integration Toolkit: 

Web Services Integration Toolkit Sessions LIFETIME_SESSION: This is the default session type. The session begins when the applications Impl object is created and the session ends when the remove method is called NO_SESSION: The session begins when a method call is made on the application and the session ends when that call returns. The lifetime of the session is a single method call TX_SESSION: The session begins when the client logs into the application by calling the methods AcmsSignIn or OpenVMSLogin of the application Impl object. The session ends when the client calls the methods AcmsSignOut or OpenVMSLogOut

Web Services Integration Toolkit: 

Web Services Integration Toolkit Runtime configurations: Not reusable Default configuration for all WSIT out-of-process applications An application is not reusable when it can only be used for one client session; a new OpenVMS process is created for each session

Web Services Integration Toolkit: 

Web Services Integration Toolkit Runtime configurations: Sequentially reusable An application is sequentially reusable when it is able to process more than one client session, but requires that exactly one session be active at a time The application must initialize its state before processing the next client session; the OpenVMS process is kept in the system

Web Services Integration Toolkit: 

Web Services Integration Toolkit Runtime configurations: Concurrently reusable An application is concurrently reusable when it can be called from multiple clients without regard to the order of the clients’ sessions The application processes one client call at a time

Web Services Integration Toolkit: 

Web Services Integration Toolkit Runtime configurations: Concurrently reusable with multiple threads An application is concurrently reusable and thread-safe when it can be called from multiple clients, at the same time, on multiple threads Has to be written using thread-safe languages and methods
