www.opitz-consulting.com Digital transformation is on its way and the industry is required to adopt new concepts and techniques, like the Internet of things (IoT), Cloud and Enterprise Mobility. As a matter of that, new business models arise, which need to be evaluated by companies to not lose market shares and stay in touch with the competitors. Gartner’s vision of Bi-modal IT seems to become more and more the reality, which besides all chances, also brings a lot of challenges companies have to deal with. One essential topic for implementing the ideas of Bi-modal IT is API Management – at least from our point of view. In addition, it is also a key enabler to define a solid strategy, in order to meet the challenges with respect to digital transformation. Our experts Sven Bernhardt and Danilo Schmiedel held this session at DOAG 2016 in Nuremberg.

API Management: Why it matters!

What is an API?
¢ Application Programming Interface (API) is a set of routine definitions,
protocols, and tools for building software and applications
¢ Expresses a software component in terms of its operations, inputs,
outputs, and underlying types, defining functionalities that are
independent of their respective implementations

API Management | What it is not!
¢ API Management is not a technology or platform
¢ API Management is not
¢ Only API Lifecycle Management
¢ SOA or SOA Governance
¢ Integration-based architecture
¢ Monolithic applications

It’s not just an API Gateway!

11. © OPITZ CONSULTING 2016 API Management: Why it matters! Seite 11
API Gateway vs. ESB (?)
API Gateway
¢ Acts as a central entry point to a
company
¢ Exposes public APIs
¢ Should not implement any
business logic
¢ Responsible for API analytics, like
usage tracking
ESB
¢ Acts a central integration backbone
¢ Used internally for integrating
heterogenous systems and
services
¢ Should not expose functionality to
the outside world
¢ Provides new internal services and
APIs

API Management maximizes the benefits of APIs
¢ Security
¢ Ensure that only the right consumer can access the right resources
¢ Prepare a defense from potential attacks on your infrastructure
¢ Analytics & Insights
¢ Understand how your API is discovered, used and by whom
¢ Stay aware of important happenings in your API ecosystem
¢ Agility
¢ Scope interfaces by resource, method, and field
¢ Manage access quantity by application, API, resource, and plan
¢ Route requests to the optimal service
