Quick & Lean Integration



The field of Integration is constantly evolving. ...

The field of Integration is constantly evolving.

At one end comprehensive Integration/SOA suites are being released by big vendors such as IBM, Oracle, SoftwareAG.

But these Integration/SOA Suites (most of them comprising of 10 different components - each catering to a specific Integration/SOA need) are beyond the reach of many mid-sized businesses.

Thats where two new integration methodologies seem to have emerged in the past one year or so.

I have tried to capture this development in the attached presentation.

    Quick & Lean Integration Quick & Lean Integration Presentation Transcript

    • Oct 2010 Satish Dadha Quick & Lean Integration – For Mid-Sized Organizations
    • Agenda
      • Growing Need for Integration
      • Ways to fulfill Integration Needs
      • Integration Needs of Mid-sized Organization
      • Game Changers:
        • Integration using XML Appliances
        • IaaS
      • Conclusion
    • Need for Integration
      • Applications today rarely live in Isolation
      • Users expect instant access to all business functions an enterprise can offer regardless of which system the functionality may reside in
      • Enterprises today have multiple systems with their own varying data and transport protocols – All these need to interface with each other to deliver business functionality
      CRM Order Mgmt Inventory Mgmt Payroll Billing ERP I N T E G R A T I O N
    • Endless Appetite for Connections
      • $10 Billion Integration Market - Gartner
      • Costs of procuring and installing integration products from leading vendors too high for mid-sized firms
      • Consequently $8 Billion in hand coded throw away integration modules are being built
      20 % - Packaged Software 80 % Hand Code
    • Application Integration – Choices
      • Integration mechanisms have evolved over time
      Message Oriented Middleware Enterprise Application Integration Suite Enterprise Service Bus Websphere MQ, JMS Q – Applications connect to common messaging system and exchange data and invoke behavior via messages Middleware to enable integration of systems and applications across the enterprise. ESB = EAI Capabilities + Conformance to SOA & Web Service standards + Value adds like Business Activity Monitoring, Rules Engine Point 2 Point Connectivity File Transfer, Shared DB, Remote Procedure Invocation
    • Application Integration – Choices
      • EAI & ESB Tools have wide ranging built in capabilities
      • They are designed to integrate dozens to hundreds of applications
      • They take care of requirements like:
        • Reliable Messaging
        • Centralized Policy Management
        • Business Activity Monitoring
      • Of course all these features come at a premium – Software License costs, Specialist Resources etc
    • Do Mid-sized Firms need all of this?
      • According to Gartner only 10% of enterprises need all the features of an EAI Solution
      • Most mid-sized businesses need to integrate fewer than 10 applications
      • Most of all smaller firms need quicker ROI – They cannot afford the overhead and time required for EAI Solutions
      • !!!!! Using Vendor EAI solutions for Mid-sized firms may be akin to using Chainsaw to open a letter !!!!!
    • So what's the solution?
      • Most of the mid-sized firms resort to custom coding to fulfill their integration needs
      • Custom coding however has 5 serious shortcomings:
        • Monopolizes specialist skills
        • Custom code may not be always reusable
        • Does not provide visibility into Integration transactions
        • Rarely scalable and flexible – Its Brittle
        • Finally custom coding turns out to be expensive in the long-run
    • Game Changers ?
      • As we have seen with the evolution of integration products the needs drive the solution
      • Two major developments are taking place to potentially cater to the integration needs of smaller firms:
        • Integration as a Service
        • Hardware XML Appliances
      • These solutions cater to “on-premise”, “cloud to cloud” & “on-premise to cloud (hybrid)” Integration requirements
    • Integration as a Service
      • IaaS is a concept similar to any other cloud offering
      • The vendor here will offer the integration functionality on a subscription basis and the user is relieved of most of the hassles associated with building a conventional integration setup
      • This is a concept that has just begun to be recognized as one of the solutions
      • It is capable of taking care of Transformation and simple BPM requirements
      • It brings along all the advantages of a cloud offering
    • Hardware XML Appliances
      • XML Appliances primarily marketed as B2B Web Services Gateway
      • These are purpose built hardware appliances capable of processing XML at wire speed
      • Currently they are also being referred to Hardware ESB/SOA Gateway
      • Some prominent products in this space are:
        • IBM DataPower
        • Cast Iron Systems (Acquired by IBM Recently)
        • Forum Sentry
    • Hardware XML Appliances
      • An illustration of IBM DataPower, being used as an SOA Gateway
      • Since these products also support – “Any to Any Transformation”, “Content Based Routing” & “Protocol Mediation (to a certain extent” they can be considered to be used for Integration requirements as well
    • Hardware XML Appliances
      • Pros
        • Integrate in days rather than months or years – Very limited coding required (XSL Transformation)
        • Very limited specialist programming skills reuqired
        • Reduced cost for initial procurement & maintenance as physical servers are not needed
        • Some of the vendors also provide “pre-built” integration templates
        • Console based setup for operations management
        • Very efficient in processing XML including encryption & decryption
      • Cons
        • Does not cover the entire gamut of integration requirements (Limited Protocol mediation support)
        • Limited/No BAM functionality
    • Conclusion
      • If the integration requirements of a client are fairly straightforward and cost is a major factor for them then we should explore these two new approaches that have emerged
      • Cognizant can play a role in meeting customer objectives in a cost efficient manner
