Architectural Discussions

At the moment I am in the middle of writing a guide to choosing the hardware architectures for our product line. One of the ideas I am playing with at the moment is boiling the factors that go into the decision into their raw levels.

A couple of years ago I attended some Project Management training and the discussion was around the "Project Management Triangle". A balanced plan requires that time, cost and quality are all in balance. If you "unblance" the triangle you can risk the project to be delayed, not meet the requirements or be cancelled altogether.

When deciding the factors for choosing architecture I came up with a similar concept. I call it the "Architectural Triangle". The dimensions in this triangle are availability, performance and maintainability. The diagram below shows both "triangles"


Availability is the measure of how available the system is against negotiated availability time (this includes Disaster Recovery). Performance is the measure of speed and some sense of size. Maintainability is the measure of skills, resources and costs associated with your site and the solution.

Just like the project management one, if you unbalance this one you can choose a hardware architecture that is really not suitable for your site.

The guidelines I am writing will take each of the basic variations of the architecture and outline the merits of each to assist customers and partners in making the right decision.


Dear Sir, Your architecture triangle describes less or more a side of a concept which I am using for scanning portfolios, considering security items, such as availabilty, integrity and confidential information. Your triangle architectur howerver fits wonderfull and logical as ane side in my pyramide theory. The impressive metafoor I used has of course an historic meaning , but is als 'proven technology' build on sustainable priciples. To develop this pyramide concept together I invite you to contact me at my email adress.

The triangle I mentioned is not new. It is based upon some old established project management principles but has been focused on what's important to IT groups.

Anthony, The Project Management triangle I thought was Scope, Time and Cost - these are the triple constraints and Quality is at the center of the triangle as any change in the above constraints should take into account the Quality aspect. Regards, Neel

I have a bit of a difficult situation . I would like to buy myself a good unlocked phone and I'm having trouble to decide on which phone to pick. First of all, i am considering the Nokia E71. My buddy has one. It appears pretty durable, and everything seemed alright, but then i began researching others. Now my biggest dilemma is to choose between the Nokia 5070 and the Samsung i900 Omnia. All suggestions are welcome.

Where could we go to have an extra marital affair? It seems to me that mated women as well as mated guys looking to have affairs all go to the same wedded dating websites. I believe that its a skillful thing together with no one should have to remain devoted to a marriage they dislike very strongly.

Where could we go to get a magic wand vibrator? They really are brilliant for women and bring very intense bouts of orgasmic pleasure.

The internet is not something you just dump something on. It's not a truck. It's a series of tubes!

Most of the times i visit a blog I see that the construction is poor and the writting bad. Regarding your blog,I could honestly say that you writting is decent and your website solid.

Wow whered you go to college Harvard, lol, newayz your a great writer, any tips?

Good luck getting people behind this one. Though you make some VERY fascinating points, youre going to have to do more than bring up a few things that may be different than what weve already heard. What are trying to say here? What do you want us to think? It seems like you cant really get behind a unique thought. Anyway, thats just my opinion.
