Welcome to the NZRT Wiki Podcast. Today we’re looking at Togaf Application Platform Service Categories.

If you’ve ever wondered what sits underneath an enterprise architecture — what kinds of services an application platform actually needs to provide — this episode breaks that down for you. TOGAF defines a comprehensive set of service categories, and together they describe every major capability a platform must support. Let’s walk through them one by one.

We start with Data Interchange Services. These cover how data moves and transforms between systems. Think document typing and conversion, graphics interchange, electronic data interchange, fax services, and raw graphics interface functions. It also includes text processing, document processing, publishing, video, audio, and multimedia processing functions, along with media synchronisation, information presentation and distribution, and hypertext functions. Essentially, anything to do with getting data from one form or place to another.

Next are Database Management System services. These include object-oriented database management, file management, query processing, screen and report generation, networking and concurrent access, and data warehousing. These are the services that let your platform store, retrieve, and present structured data.

Graphics and Imaging Services cover graphical object management, drawing services, and imaging functions. If your platform needs to render or manipulate visual content, this is the category that supports it.

Location and Directory Services are all about finding things. Directory services, special-purpose naming, service location, registration, filtering, and accounting services all live here. These help systems and users locate resources across a network.

Network Services are broad. They cover data communications, electronic mail, distributed data and file services, distributed naming and time services, remote process access, and remote print spooling. On top of that, you’ve got enhanced telephony, shared screen functions, video conferencing, broadcast functions, and mailing list functions. This category is the backbone of how distributed systems talk to each other.

Operating System Services keep things running at the foundation. Kernel operations, command interpreter and utility services, batch processing, and file and directory synchronisation services all sit here.

Software Engineering Services support how software is built. This includes programming language services, object code linking, computer-aided software engineering tools, graphical user interface building, scripting languages, language bindings, run-time environments, and application binary interface services. If you’re building or deploying software on the platform, these services are what you depend on.

User Interface Services are what users actually interact with. Graphical client and server services, display objects, dialogue support, printing, computer-based training and online help, and character-based services all fall into this category. This is where the platform meets the person.

Security Services are critical. You’ve got identification and authentication, system entry control, audit services, access control, non-repudiation, security management, trusted recovery, encryption, and trusted communication services. Together these ensure that only the right people and systems can do the right things, and that there’s a record when they do.

System and Network Management Services cover the operational side of keeping everything running. User management, configuration management, performance management, availability and fault management, accounting management, print management, network management, backup and restore, online disk management, licence management, capacity management, software installation, and trouble ticketing services. This is your operations team’s toolkit, built into the platform definition itself.

Finally, Object Request Broker Services handle distributed object communication. These include implementation repository services, installation and activation, interface repository services, and replication. Then there’s a rich set of common object services covering change management, collections, concurrency control, event management, externalisation, licensing, lifecycle management, naming, persistent object services, properties, query services, relationship services, start-up services, time services, trading services, and transaction services. This category is what lets distributed components find each other, communicate reliably, and maintain consistency across a system.

So when you look at all of these together — eleven major categories, hundreds of individual service types — you get a picture of just how comprehensive the TOGAF application platform model is. It’s not just about what your application does. It’s about every layer of capability the platform must provide to make that application possible.

That’s it for this episode of the NZRT Wiki Podcast. Thanks for listening.
