Annual spend will quadruple by the end of the decade, from $140 million in 2014 to $660 million in 2020. International sales will take the global market over the billion dollar mark." -Forrester, June 2015. "Within 2 years, at least one-third of Industry Clouds will support industry standard APIs, helping companies connect more easily and securely, accelerating the Digital Transformation Economy.” - IDC FutureScape: Worldwide Cloud 2018 Predictions “In Three Years, 75% of Organizations Will Have Core Cloud API Strategies as Part of Their Digital Transformation Architectures to Enable an API-Driven Economy, with New Products Built on Digital Platforms That Orchestrate Information Exchange Between Multiple Organizations in Their Ecosystems ” - IDC FutureScape: Worldwide Cloud 2018 Predictions. API Market Opportunity §Forrester predicts that the API Management market will be $1B by 2019. §Considering the IBM Z Application Server market is roughly 20% of the Application Platform market, we can see an IBM Z API Market opportunity of $200M.
- 4. 4 Key Drivers for APIs Regulations & Standards Architectural Simplification Leverage new digital and cognitive services Participate in the API Economy Business Agility • PSD2 • Open healthcare APIs • Standardize integration layer on REST / Json • Simplified integration architecture with reduced components. • March towards microservices architecture • Enrich your z applications by consuming cloud native services • Watson – cognitive services • Google – Location, etc. • Payment gateway (apple pay) • Partner APIs • Publish APIs from your app assets for wider consumption. • Monetize application assets • Make your z assets composable • Faster response to market needs
- 5. API Centric Digital Transformation - opportunities Enterprises are on a digital transformation path to stay relevant and respond to market needs in the quickest possible time. APIs are at the center of digital transformation. These are some of the initiatives that will potentially require APIs to be created for mainframe applications or data. Position IBM z/OS Connect Enterprise Edition as the strategic and standard solution for one or more of these scenarios. • Hybrid Applications, Cloud and micro services • Move towards micro services architecture and expose services as APIs • Consume partner APIs and other cloud based services (location, cognitive, etc) • Service enablement of applications • Refactor monolithic application into fine grained services and expose them as APIs • Open API Initiatives (regulations) • PSD2 • BIAN • Open healthcare APIs • APIfication / API economy • Create an API channel to Z assets and monetize them • Blockchain • Integrate existing application assets with blockchain • Data as a service • Data is the new oil, and data on Z is invaluable! Expose them as APIs • Make data available to system of insights (analytics engine)

- 25. §Does a service interface already exist? –You might already have SOAP web services running in the SOR that can be reused by an API Gateway –However exposing a REST interface directly might be more convenient and streamlined §What service granularity is exposed by the SoR application? –It is possible that the granularity of the existing services will need to be adapted e.g to perform service aggregation §Do services need to be discovered? –To facilitate fast and agile development of SOE applications (e.g mobile apps), you need a way to allow developers to determine quickly what services are available Access Layer
- 26. §Is an ESB used in the existing application integration architecture? –An ESB may already be used for data and protocol conversion, and may also have a governance role in applying policies such as authentication, audit, logging, service versioning etc. –Most ESBs have been enhanced in recent years to support REST/JSON §How many types of service requesters and service providers need to be supported by the application integration architecture? –The value of an ESB is partly determined by the range of different service requesters and providers that need to be integrated §Does the mobile solution need to support asynchronous requests? –An ESB is able to provide correlation for asynchronous invocations through a messaging engine Integration Layer: Enterprise Service Bus
- 27. IBM Client Center Montpellier API gateway considerations • Do you need to make your business services more usable? • APIs should be simple to look up from an easily browsable and searchable catalog • Do you want to reach new markets, customers, and partners? • By making core business functions available as APIs to business partners, a business can reach more customers • Do you need more control over who uses your business services? • The API gateway can check the entitlement for the invoking application and the collected audit data can then be analyzed and presented as a report for gaining insight into API invocation • Do you need to charge consumers for accessing your business services? • The audit data that is collected by the API gateway can be used for charging
- 28. Security Gateway • Is a security gateway used in the existing application integration architecture? • A security gateway allows the decoupling of security policy from the underlying application • Extending the security gateway to control access to APIs makes sense • What are the specific security requirements of the hybrid application? • Type of user (employee, client, partner, and so on) • Type of device (cloud, mobile, IoT, and so on) • Type of SoR services that are required by the service requester • Authentication, authorization, and audit requirements • Confidentiality and data integrity requirements • Company and industry standards that must be respected
