Erik Wilde (@dret): Continuous API Management

(2) Summary

APIs are the connective fabric that powers digital transformation. Managing APIs well is essential in order to keep track of the large and continuously growing landscape of APIs in large organizations. As large organizations increasingly embark on digital transformation journeys, patterns and practices emerge, such as products as APIs, API first, API guidelines, API governance, and API platforms. Continuous API Management (CAM) focuses both on individual APIs and on the API landscape and helps organizations to better manage and evolve their digital capabilities. As a way to better assess the current status and to define a way forward, there are five CAM compasses that help organizations with API strategy, program, and landscape, and with individual API products as well as with their API consumption practices. Based on these compasses and the pillars of digital transformation (business, organization, technology), we can show how API initiatives in large organizations get underway and start delivering value to the organization from the very beginning.

Digital Transformation and APIs Erik Wilde (@dret): Continuous API Management

(10) Digital Transformation is Global

Digital Transformation and APIs Erik Wilde (@dret): Continuous API Management

(11) Digital Transformation Goals

Digital Transformation means adapting an organization's strategy and structure to capture opportunities enabled by digital technology. (Nathan Furr and Andrew Shipilov, Digital Doesn't Have to Be Disruptive, Harvard Business Review 97(4), July/August 2019, pp. 94-103.) [https://hbr.org/2019/07/digital-doesnt-have-to-be-disruptive]

Increasing speed because the world is changing faster
Decreasing coupling because the world is getting more complex
Transforming the organization so that it can implement business goals more quickly
Transforming IT to be aligned with the organization's structure and speed

API Products Erik Wilde (@dret): Continuous API Management

(18) API Product Lifecycle

API Products Erik Wilde (@dret): Continuous API Management

(19) External or Internal?

External: Participating in the API Economy becomes increasingly beneficial
- Interfacing with customers/partners becomes easier
- The number of API-ready customers/partners keeps increasing
- The network effect [https://en.wikipedia.org/wiki/Metcalfe%27s_law] guarantees for the trend to continue
Internal: Digital transformation results in many internal APIs
- Decompose the organization into loosely coupled autonomous teams
- Teams create products and expose them as APIs
- Teams can build on existing capabilities by consuming their APIs

API Products Erik Wilde (@dret): Continuous API Management

(20) Jeff Bezos' Services Mandate [https://gist.github.com/chitchcock/1281611]

Famous small set of design and implementation rules
- Teams must expose functionality through services
- Communication happens only through service interfaces
- There are no hard guidelines for service design
- Internal/external service is a matter of policy, not one of design
Going against the let's pick a platform spirit of old-school SOA

API Products Erik Wilde (@dret): Continuous API Management

(21) The External/Internal API Fallacy

API Products Erik Wilde (@dret): Continuous API Management

(22) Transaction Costs Define Business

A firm is likely therefore to emerge in those cases where a very short term contract would be unsatisfactory. […]
We may sum up this […] argument by saying that the operation of a market costs something and by forming an organisation and allowing some authority (an entrepreneur) to direct the resources, certain marketing costs are saved. The entrepreneur has to carry out his function at less cost, taking into account the fact that he may get factors of production at a lower price than the market transactions which he supersedes, because it is always possible to revert to the open market if he fails to do this.

API Products Erik Wilde (@dret): Continuous API Management

(23) Microservices: Webby Architecture for Enterprises

Microservice Architecture (MSA) is not about containers
MSA is about self-contained product implementations
MSA is about allowing products to evolve independently
The hardest aspect of MSA is to get loose coupling right
