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

Capability
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.

This week we're attending SYS-CON Event's DevOps Summit in New York City. It's a great conference and energy behind DevOps is enormous. Thousands of attendees from every company you can imagine are focused on automation, the challenges of DevOps, and how to bring greater agility to software delivery. But, even with the energy behind DevOps there's something missing from the movement. For all the talk of deployment automation, continuous integration, and cloud infrastructure I'm still not se...
IT data is typically silo'd by the various tools in place. Unifying all the log, metric and event data in one analytics platform stops finger pointing and provides the end-to-end correlation. Logs, metrics and custom event data can be joined to tell the holistic story of your software and operations. For example, users can correlate code deploys to system performance to application error codes. In his session at DevOps Summit, Michael Demmer, VP of Engineering at Jut, will discuss how this can...

The most often asked question post-DevOps introduction is: “How do I get started?” There’s plenty of information on why DevOps is valid and important, but many managers still struggle with simple basics for how to initiate a DevOps program in their business. They struggle with issues related to current organizational inertia, the lack of experience on Continuous Integration/Delivery, understanding where DevOps will affect revenue and budget, etc. In their session at DevOps Summit, JP Morgenthal...
Sharding has become a popular means of achieving scalability in application architectures in which read/write data separation is not only possible, but desirable to achieve new heights of concurrency. The premise is that by splitting up read and write duties, it is possible to get better overall performance at the cost of a slight delay in consistency. That is, it takes a bit of time to replicate changes initiated by a "write" to the read-only master database. It's eventually consistent, and it'...
Data center models are changing. A variety of technical trends and business demands are forcing that change, most of them centered on the explosive growth of applications. That means, in turn, that the requirements for application delivery are changing. Certainly application delivery needs to be agile, not waterfall. It needs to deliver services in hours, not weeks or months. It needs to be more cost efficient. And more than anything else, it needs to be really, dc infra axisreally, super focus...
Overgrown applications have given way to modular applications, driven by the need to break larger problems into smaller problems. Similarly large monolithic development processes have been forced to be broken into smaller agile development cycles. Looking at trends in software development, microservices architectures meet the same demands. Additional benefits of microservices architectures are compartmentalization and a limited impact of service failure versus a complete software malfunction. ...
Discussions about cloud computing are evolving into discussions about enterprise IT in general. As enterprises increasingly migrate toward their own unique clouds, new issues such as the use of containers and microservices emerge to keep things interesting. In this Power Panel at 16th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the state of cloud computing today, and what enterprise IT professionals need to know about how the latest topics and trends affect t...
Containers have changed the mind of IT in DevOps. They enable developers to work with dev, test, stage and production environments identically. Containers provide the right abstraction for microservices and many cloud platforms have integrated them into deployment pipelines. DevOps and Containers together help companies to achieve their business goals faster and more effectively. In his session at DevOps Summit, Ruslan Synytsky, CEO and Co-founder of Jelastic, reviewed the current landscape of...
Explosive growth in connected devices. Enormous amounts of data for collection and analysis. Critical use of data for split-second decision making and actionable information. All three are factors in making the Internet of Things a reality. Yet, any one factor would have an IT organization pondering its infrastructure strategy. How should your organization enhance its IT framework to enable an Internet of Things implementation? In his session at @ThingsExpo, James Kirkland, Red Hat's Chief Arch...
Manufacturing has widely adopted standardized and automated processes to create designs, build them, and maintain them through their life cycle. However, many modern manufacturing systems go beyond mechanized workflows to introduce empowered workers, flexible collaboration, and rapid iteration. Such behaviors also characterize open source software development and are at the heart of DevOps culture, processes, and tooling.
SYS-CON Events announced today that JFrog, maker of Artifactory, the popular Binary Repository Manager, will exhibit at SYS-CON's @DevOpsSummit Silicon Valley, which will take place on November 3–5, 2015, at the Santa Clara Convention Center in Santa Clara, CA. Based in California, Israel and France, founded by longtime field-experts, JFrog, creator of Artifactory and Bintray, has provided the market with the first Binary Repository solution and a software distribution social platform.
Conferences agendas. Event navigation. Specific tasks, like buying a house or getting a car loan. If you've installed an app for any of these things you've installed what's known as a "disposable mobile app" or DMA. Apps designed for a single use-case and with the expectation they'll be "thrown away" like brochures. Deleted until needed again. These apps are necessarily small, agile and highly volatile. Sometimes existing only for a short time - say to support an event like an election, the Wor...
The cloud has transformed how we think about software quality. Instead of preventing failures, we must focus on automatic recovery from failure. In other words, resilience trumps traditional quality measures. Continuous delivery models further squeeze traditional notions of quality. Remember the venerable project management Iron Triangle? Among time, scope, and cost, you can only fix two or quality will suffer. Only in today's DevOps world, continuous testing, integration, and deployment upend...
DevOps tends to focus on the relationship between Dev and Ops, putting an emphasis on the ops and application infrastructure. But that’s changing with microservices architectures. In her session at DevOps Summit, Lori MacVittie, Evangelist for F5 Networks, will focus on how microservices are changing the underlying architectures needed to scale, secure and deliver applications based on highly distributed (micro) services and why that means an expansion into “the network” for DevOps.
Containers are changing the security landscape for software development and deployment. As with any security solutions, security approaches that work for developers, operations personnel and security professionals is a requirement. In his session at DevOps Summit, Kevin Gilpin, CTO and Co-Founder of Conjur, will discuss various security considerations for container-based infrastructure and related DevOps workflows.
