Continuing with the theme of “What is a service?”, I’m thinking it’s best to think of it in terms of a “service contract.”

The notion of a service is kind of squishy. It’s a repeatable business task, hopefully well encapsulated so that it can be requested in a simple interaction and performed in a unit of work. That makes sense to business people and can be gathered as requirements, but is rather vague for us technical people (especially when trying to achieve business/it alignment). So we tend to fall back on a service interface as being the technical definition of a service. But as I discussed in service behavior, a service is a lot more than just its interface.

So how can we describe a service with some rigor? I’m coming to think of that as a service contract (which I discuss more on my wiki). In short, a service contract captures a service’s behavior, interface, policies, and service level agreement (SLA). It’s everything that a requestor and provider of a service must agree on so that the requestor knows what it can depend on and a provider knows what it must do.

For us technical people, I think that thinking of a service (a task) as a contract (an agreement that describes the task) will help us be a lot more specific and make good use of the ideals of SOA.

Web 2.0 is at the center of a wave of excitement concerning how enterprises
— commercial or public organisations — are trying to exploit the current
generation of Internet technologies. This four-part article series examines aspects
of Web 2.0 relevant to the enterprise. In this first installment, take a look at the
business and technical drivers behind Web 2.0, the challenges and opportunities Web
2.0 presents to enterprises, and the relationship between Web 2.0 and
Service-Oriented Architecture (SOA).

Lately I’m thinking more about “What is a service?” and deciding that one of the most important aspects is what I’ll call “service behavior.”

When we talk about services (as in the parts of an SOA), we tend to talk about interfaces a lot. But it doesn’t take long to decide that a service is a lot more than an interface. We care more about what a service does than its interface for interacting with it.

So why the focus on interface? Because, I think, an interface is more quantifiable; you can make it machine readable, describing it with a programming construct such as WSDL or a Java or .NET interface. A code compiler can then check code against that declaration for correctness. Inheritance creates rules for how one interface is allowed to extend another. Like I talked about in declared interfaces, interfaces are definite–either they match or they don’t. That’s easier for us technology types to deal with.

Behavior–what a service does–is more fleeting, which I think explains why us technology types deal with it less. But it’s what the users care about most; the business people in an enterprise probably don’t care much about the interfaces that services have, but they certainly care about what the services do and whether they do it correctly.

As I discussed in What Is Behavior?, behavior is a bit like dark matter–it can’t be measured directly, only indirectly. We measure behavior indirectly through testing–providing known inputs and measuring the outputs to confirm that they meet expectations. There’s been some efforts to describe behavior directly the way we do interfaces–declared behavior–but that doesn’t really seem to have taken hold thus far. For the time being, behavior can’t be described and measured directly like interfaces, only indirectly via testing. (And it doesn’t help that testing tends to be treated as computer science backwater.)

So a service is both interface and behavior (and probably more). The technical people focus on the interface while the business people focus on the behavior. To do a good job with services and SOA, we technical people are going to need to focus on behavior as well.

I’ve started to capture some of these thoughts in service behavior.
