Roy's Technology Diary

A lot has been said and done about services on the cloud lately and "Platform as a Service" (PaaS) is probably one of the most popular buzz-word that's been around for quite sometime now. However, I sincerely feel that the common man (read as "developer") is yet to get a taste of what it really means. Now, this very paradigm seems to be soon changing, with VMWare Cloud Foundry. Cloud Foundry is the world’s very first open Platform as a Service (PaaS). It is designed to help developers easily create web applications, using multiple programming frameworks including Spring for Java, Ruby on Rails and Sinatra for Ruby; that can run upon public and private cloud environments, with just about no additional learning curve. So, by now if you are dreaming of a possibility to port your existing web-applications to the cloud with minimal efforts, then let me give you the good news - "it's all possible here..." Well, looks like i've done a lot of sales t...

In the previous article, we glanced through Enterprise Architecture as a whole and also discussed the need for an Enterprise Architecture Framework, like TOGAF. With this article we shall continue exploring TOGAF further, and discusses TOGAF's Architecture Development Methodology (ADM). The Architecture Development Methodology (ADM) The Architecture Development Methodology (ADM) provides a proven and repeatable process for developing architectures. The Scope The scope of ADM includes or encompasses the below listed activities, which are generally carried out in iterative cycles of continuous architecture definition and realization; thus aiding a controlled transformation of an enterprises in response to business goals and opportunities - Establishing an architecture framework Developing architecture content Transitioning Governing the realization of architectures Implementation Phases The implementation of ADM could be envisioned across the following phases - Preliminary Initiation...

Lately I've been studying/reading The Open Group Architecture Framework (TOGAF), and I simply could not resist from appreciating the structural approach that it introduces towards envisioning and capturing Enterprise Architecture. I therefore thought of initiating a series of articles herein, with the sole purpose of sharing, simplifying and promoting the framework especially amongst the architecture aspirants out there who follow and read my blog. This write-up, which is the first one in the series, intends to provide a brief overview on Enterprise Architecture and then further goes on to illustrate the need for an Enterprise Architecture Framework. Preface ISO/IEC 42010: 2007 defines "architecture" as: "The fundamental organization of a system, embodied in its components, their relationships to each other and the environment, and the principles governing its design and evolution." TOGAF embraces but does not strictly adhere to ISO/IEC 42010: 2007 terminology. ...
