Value of Service Enablement

Reach, Reuse and Manageability are key to success in the Enterprise

Previous efforts focused on Reuse and some Reach

Success with Reach and Reuse leads to more difficulty with Management

Explicit Machine Readable PolicyMove "policy" issues out of code -> be more productive

Must treat Services as a SystemDifficult to even talk about with out a Model

Enterprise Service Orientation Maturity Model (ESOMM)

Maturity Models descend from Carnegie Mellon’s CMM

Some current “SOA Maturity Models” move Best Practices instead of Best Principles

CMM was process focused because it was a Maturity Model for the Software Development Process

Levels in a Maturity Model should be Self-Evident

The levels are only useful in so much as they define “meaningful” states.

Maturity Models should be PrescriptiveNeed to show where you are, where you wish to be and how to get there.

ESOMM Maturity Levels

Enterprise is capable of writing and consuming standards conformant Services with excellent reach

Enterprise implements, consumes, and reuses Services efficiently and consistently

Enterprise can effectively Manage and Support large numbers of Services with guaranteed SLA's

Enterprise is capable of aggregating Services and extending their use beyond its own borders

Managed ServicesServices as a System

Service is entirely VirtualThe "Operation" is really the "Service“

Service Definition (interface) distinct from Service Implementation

Service Definition Consists of Four Parts:

Endpoint; Message; Policy; Context (Intent + State)

The "Service Network" requires a "Runtime Engine"

Executable Policy; Schema Bank; Service Blocks; etc.

Topology is an implementation detailThis isn't about the ESB!

Managed Services Engine Reference Architecture

The Managed Services Engine

processes Service Requests with

Messaging, Brokering, and Dispatching..
