Decision Parameters On Choosing The Technology Platform

Recently I was asked to list down the decision parameters on choosing a technology platform. Here is a list I've quickly assembled. Comment on if you have more things to add.

-> Client Choice/Preference

Step 1- Client's choice/alignment with technology platform
Step 2- Existing infrastructure client has in place to support any of the suggested technology platform.

-> Cost/Budget

Step 1- Implications on hardware and software requirements (like hosting platform cost, infrastructure cost etc)
Step 2- implications on resource requirements (availability of resources, training cost etc)
Step 3- Cost comparison of inhouse development vs outsourcing for each technology

-> Existing Dependancies and code base

Step 1- Is this an end to end project, re-write, take over or a migration?
Step 2- If not end to end, do you have any existing dependancies and code base

-> Platform maturity

Step 1- Find out whether the suggested platform can cover all requirements and future requirements.
Step 2- Can satisfy interfacing requirements? (eg. RoR is not mature for handling web services)

-> Available frameworks

Step 1- Any existing frameworks/open source tools are already available? (Eg: OSCommerce/PHP for E-Com).
Step 2 - If Step 1, what is the investment for building expertise in this existing framework to reduce TCO?
Step 3- Do you have any existing frameworks/reusable components to reduce TCO?

-> Complexity and size (Estimated using FP or something)

Step 1 - Estimated size of the project
Step 2- What is the cost comparison between platforms? (based on finding out time to execute for each platform based on total FP)
Step 3- Do you have any existing practices successfully applied earlier to execute the project in a technology platform?

-> Project model (Time and expense/Fixed bid etc)

Step 1 - If Fixed Bid, which platform is suitable for quickest development and deployment?
Step 2- Do you have any existing practices successfully applied earlier to execute the project in a technology platform?

-> Project Type (Desktop/web App/Services etc)

Step 1 - Feasibility analysis of candidate technology platforms for this project (eg. RoR is not suited for a Windows Service application)
Step 2- Eliminate technologies that are not feasible

-> Interfaces to deal with

Step 1 - Feasibility analysis of candidate technology platforms for interface support (eg. If you are consuming REST services, RoR has a weightage)
Step 2- Identify platform specific interface requirements.

-> Expected Scalability And Performance

Step 1 - Identify support for OLAP/OLTP scenarios in the project.
Step 2- Identify minimum response time requirements.
Step 3- Weightage based on POCs constructed under various technologies or existing data or previous experience.

-> Internal expertise availability

Step 1 - Weightage based on our internal expertise and resource availability
Step 2- Training costs incurred

Creating a quick Todo listing app on Windows using IIS7, Node.js and Mongodb

As I mentioned in my last post, more and more organizations are leaning towards Web Oriented Architecture (WOA) which are highly scalable. If you were exploring cool, scalable options to build highly performing web applications, you know what Node.js is for.After following the recent post from Scott Hanselman, I was up and running quickly with Node.js. In this post, I’ll explain step by step how I’ve setup Node.js and Mongodb to create a simple Todo listing application.Setting up Node.jsThis is what I’ve done.1 – Goto http://nodejs.org/, scroll down and download node.exe for Windows, and place it in your c:\node folder2 – Goto IIS Node project in Git at https://github.com/tjanczuk/iisnode, download the correct ‘retail’ link of IIS Node zip file (I downloaded the already built retail package, otherwise you can download and build from the source).3 – Extract the zip file some where, and run the install.bat or install_iisexpress.bat depending on your IIS Version. If you don’t have IIS in…

Top 7 Coding Standards & Guideline Documents For C#/.NET Developers

Some time back, I collated a list of 7 Must Read, Free EBooks for .NET Developers, and a lot of people found it useful. So, I thought about putting together a list of Coding Standard guidelines/checklists for .NET /C# developers as well.As you may already know, it is easy to come up with a document - the key is in implementing these standards in your organization, through methods like internal trainings, Peer Reviews, Check in policies, Automated code review tools etc. You can have a look at FxCop and/or StyleCop for automating the review process to some extent, and can customize the rules based on your requirements.Anyway, here is a list of some good Coding Standard Documents. They are useful not just from a review perspective - going through these documents can definitely help you and me to iron out few hidden glitches we might have in the programming portion of our brain. So, here we go, the listing is not in any specific order.1 – IDesign C# Coding StandardsIDesign C# coding stand…

MVVM - Binding Multiple Radio Buttons To a single Enum Property in WPF

I had a property in my View Model, of an Enum type, and wanted to bind multiple radio buttons to this.

Firstly, I wrote a simple Enum to Bool converter, like this.

public class EnumToBoolConverter : IValueConverter { #region IValueConverter Members public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { if (parameter.Equals(value)) return true; else return false; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { return parameter; } #endregion }

And my enumeration is like

public enum CompanyTypes { Type1Comp, Type2Comp, Type3Comp } Now, in my XAML, I provided the enumeration as the ConverterParameter, of the Converter we wrote earlier, like
