Service Concepts 101

What is a service?

The use of the term ‘Service' is somewhat overloaded. Everyone will have heard or used the terms Business Services, IT Services, Software Services, and now Cloud Services, and yet often there is much confusion and misunderstanding in their use. As my colleague David Sprott suggested in a CBDI Journal Report, "Everything is a Service" . In that report David suggested that the idea that "everything is a service" could be developed to clarify the taxonomy for Cloud Services and Services in the form of a Unified Service Model that would deliver convergence of business and IT perspectives.Consequently, I have penned a research note available on Everware-CBDI site that provides a concept model that explores the basic concepts of Service and Service-Orientation taking into account this broad perspective including Business Service, IT Services, Software Services, Cloud Services and even Human Services.

What Is a Service?
Readers will be familiar with the basic concept of a Service.  That is, where someone or something provides a Service to another.The notion that someone or something offers a Service to another introduces the concept of the Service Provider and Service Consumer as illustrated in Figure 1. A Service Provider is as its name suggests is someone or something that provides a Service. And the Service Consumer is someone or something that consumes or uses the Service.Real World Example: A logistics company provides a Goods Delivery Service. This is used by a manufacturer to ship goods to its clients.The logistics company is the Service Provider.  The manufacturer is the Service Consumer.

Figure 1: Service Consumers and Providers

The reason a Service Provider is able to provide the Service is because they possess the Capability required to do so.A Capability is the power or ability to perform some function. We may think of a person, an organization or something (a machine, or some technology) as having the Capability to perform some function. In turn the Service Provider may offer their Capability to others, in the form of a Service. Meanwhile, a Service Consumer is someone or something that requires the Capability. Hence we may understand a Service as a Capability offered by a Service Provider to a Service Consumer Real World Example: A logistics company has the Capability to deliver goods.  Therefore it is able to offer a Goods Delivery Service to others.

Figure 2: Service and Capability

Types of Service
In the real world example used so far, a logistics company provides a Goods Delivery Service to a manufacturer.This may be referred to as a Business Service, as it reflects the nature of the activity - where one business is providing its services to another. It is also normally offered on a commercial basis, and may be considered as a Business Service because business is being transacted through its use.We can think of Business Service as a particular type of Service.Other types of Service commonly used in an IT context are:

  • IT Service, where the IT department (or third party) provide a service to the business
  • Software Service, where a unit of software provides a service to another software unit
  • Cloud Service, where a Software Service is provided over a network and conforms to cloud computing principles

We can even consider a Human Service where one person provides services to another and relies upon human resources to provide the required Capability.Regardless of the type of Service, the concepts discussed so far still hold true.Whether it is a Business Service, an IT Service or a Software Service, Cloud Service, or a Human Service, they still all provide a Capability, and are all provided by a Service Provider and used by a Service Consumer.

Developing software for the Internet of Things (IoT) comes with its own set of challenges. Security, privacy, and unified standards are a few key issues. In addition, each IoT product is comprised of at least three separate application components: the software embedded in the device, the backend big-data service, and the mobile application for the end user's controls. Each component is developed by a different team, using different technologies and practices, and deployed to a different stack/...

As-a-service models offer huge opportunities, but also complicate security. It may seem that the easiest way to migrate to a new architectural model is to let others, experts in their field, do the work. This has given rise to many as-a-service models throughout the industry and across the entire technology stack, from software to infrastructure. While this has unlocked huge opportunities to accelerate the deployment of new capabilities or increase economic efficiencies within an organization, i...

You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud.
