Governance

Defining a SOA governance approach

Service Oriented Architecture initiative success requires creating loosely coupled consumer-provider connections, enforcing a separation of concerns between consumer and provider, exposing a set of re-usable, shared services, and gaining service consumer adoption. Many teams find a SOA or REST focus may not improve IT agility, but result in simply swapping out IT toolsets, message formats, and protocols.

SOA Governance mitigates risk in failing to deliver the [A] in SOA.

Service Portfolio is [A] in SOA

A key SOA end-goal is a service portfolio exhibiting a clean architecture. Technical and industry vertical business domain models are useful starting points for development of an organization’s unique service portfolio. Service design and interface design are small pieces in a larger set of programs that must be managed in order to establish highly effective IT service delivery, collaboration, and trust.

SOA Perspective and API Echo

The SOA perspective is reverberating into an API echo. During past SOA craze days  (2003-2008), proponents pitched SOA’s lofty benefits from both business and technical perspectives.   The benefits are real, yet sometimes very difficult to obtain. Surprisingly, today’s API proponents target similar benefits, but with an execution twist.

Defining a Service Oriented Architecture (SOA) Mindset: Big SOA or Small SOA

How would you define your team’s Service Oriented Architecture (SOA) mindset and the value you derive from Big SOA or Small SOA approaches?

Defining SOA

Service oriented architecture (SOA) represents a significant paradigm shift in application development techniques. SOA is a software design discipline in which application and infrastructure functionality are implemented as shared, reusable services. Each service implements a discrete task, and any application that needs to perform the task uses the shared service to do so. Teams create applications by assembling the appropriate services. After teams implement business functionality as services, an organization, their partners, and their customers should be able to mix and match these services and rapidly create new applications to support changing business requirements.

Because SOA presents an architectural goal state at odds with a long-lived legacy IT portfolio, SOA is a long-term architectural journey, and not a short-term implementation initiative.  Because APIs interconnect business capabilities inside and outside the organization, APIs can provide a platform for business stakeholders sponsoring enterprise IT renewal and pragmatic business execution.

 

The last ten years of SOA promotion, implementation, and evaluation have cultivated two distinct ways to approach SOA; Big SOA Mindset and Small SOA Mindset.

Application Services Governance best practices accelerate safe delivery

Application Services Governance is a mechanism to achieve business agility, build a responsive IT organization, and optimize IT effectiveness. Effective governance automates IT best practices, improves service levels, and facilitates safe, rapid iterations. Governance facilitates safe and rapid change by mitigating risks and reducing uncertainty when teams evolve IT systems. When enhancing governance effectiveness, successful teams smartly remixes IT skills, tooling, and processes; development and operation teams adopt agile processes, introduce automation tooling, and streamline collaboration.

Application Services Governance spans services, APIs, and applications. Don’t fall into governance gaps! Effective governance initiatives unify SOA governance, API governance, application governance, security governance, development governance, and infrastructure governance into a comprehensive and interconnected DevOps perspective.
