IT Infrastructure

IT Infrastructure consists of Clientware, Middleware, Serverware, Manageware, and Platforms, as illustrated below:

In the above diagram, Clientware refers to software that runs on clients, including the following sub-categories:
  • Office (e.g., word processors and spreadsheets)
  • Internet (e.g., web browsers and e-mail clients)
  • Graphics ( e.g., bitmap and vector)
  • Publishing

Serverware -- software running on servers -- refers to the following sub-categories:
  • Basic (e.g., file server and print server)
  • Internet (e.g., web server and application server)
  • Database (e.g., SQL server and XML server)
  • Content

Middleware provides the glue that connects clients and servers. Its sub-categories include:
  • Formats & Protocols
  • Directory & Security
  • Application Partitioning
  • Application Integration
  • Web Services

Platforms provide the base foundation for computing and communication -- consisting of:
  • Operating Systems
  • Hardware
  • Components
  • Peripherals
  • Networks

Manageware monitors and manages various segments of elements that collectively constitute infrastructure. These include the following:
  • Enterprise Managers
  • System Managers
  • Network Managers
  • Security Managers
  • Configuration Managers
  • Operations Managers
  • Problem Managers
  • Performance Managers

This is a lovely picture, Jeff.
Can you enlighten me - why is it a "roadmap"? And where does ETL fit? What about Workflow?
I guess I'm just wondering what someone is supposed to *do* with a picture like this. And what with the lines between these things blurring all the time, what would be *really* neat would be a diagram which focused on capabilities rather than "boxes".

This lovely picture is a roadmap in the sense that it helps visually show where different products fit.

The term roadmap was chosen in preference over visual taxonomy, ontology, category tree, or classification hierarchy.

Infrastructure, which graphic is depicted in this posting, is only one piece of the bigger picture for describing a complete technology portfolio.

On top of Infrastructure sits Applications which can either be built or bought. Sitting above Applications is Business Intelligence.

This three-layer four-model Technology Architecture framework specifies ETL as part of the top-level Business Intelligence model. Workflow, I prefer the terminology BPM -- Business Process Modeling/Management, is defined as part of Application Integration which is included under Middleware in the Infrastructure model.

To view in their entirety the full 3-layer and 4-model framework, see the blog posting called Technology Architecture: 3-Layers/4-Models .
