How API Enablement Drives Legacy Modernization

  1. 1. Narayanan Chathanur Director, API and Microservices, Infosys Limited Be More. Do More. Unlock Value. Deliver Innovation
  2. 2. Market forces are transforming large enterprises… 2 …and technology is at the core of this shift. Disintermediation of value chain New business models Digital vs. physical Entry barriers Nontraditional competitors
  3. 3. Renewing the core is equally important API-led legacy modernization Enterprise process centers Policy externalization ? BPO digitization Fast apps platform 3
  4. 4. Legacy modernization in the digital age. Why it matters? Growth of APIs since 200713x 43% Of IT executives believe a failure to integrate with legacy systems is the biggest barrier to implement future initiatives. 70% IT maintenance cost of the total IT budget increased because information was available in silos 39% Of overall software reuse within organizations after enabling service APIs api2cart 5 Bn Number of calls received by Google daily – served by API Enablement Number of calls served by Facebook daily 4
  5. 5. Industry challenges demanding API enablement of legacy systems Banking platforms • Rising customer expectations • Omnichannel and personalized engagements • Increase in mobile app transactions • Platforms need to cater to increasing services, channels, and products • Innovation from nonbank services and fintechs adding new source of competition Retail supply chain • Deep integration of customer experience across channels and systems for greater impact • Streamline access to internal systems for a personalized and engaging customer experience • Manage growth for dynamic and high-traffic events such as Black Friday holiday shopping Quantified healthcare • Requirements for health data interoperability • Regulation change, technology advancement, and consumer expectations • Focus on payment for outcomes instead of for services requires new business models Media • Media content must be delivered seamlessly from disparate sources and formats • Digital native non-industry upstarts seek to disintermediate established companies • Supporting the never-ending stream of new devices slows innovation 5
  6. 6. So what is holding organizations back? How to handle the monolithic code? How to bring agility? How to expose Z assets to mobile world? Is it possible to reuse existing SOA modules? Will it handle load in peak hours? Digital enablement of mainframe. Will it be a success? How to ensure security and governance? Typical Patterns: • Spaghetti application • SOA-based applications • Storedprocs for direct data access: 6
