Cloud Computing

No wait, I mean Virtualization … , I mean Grid … well no, I should say Utility … Oh, well, forget it … just find a way to save some money!

If you have been in the information technology (IT) sector for any length of time, you are probably accustomed to two IT industry absolutes: (1) never-ending hype from the hardware/software vendors and service providers; and (2) the solutions you build are generally too expensive and take too long to implement. With this in mind, I have yet to make up my own mind on “cloud computing”. However, I have been a big fan of Application Service Provider (ASP) and Business Process Outsourcing (BPO) services, which I believe is the genesis of cloud computing (CC).

All About the SSL Protocol

What is SSL?

SSL stands for Secure Socket Layer (SSL). Originally developed by Netscape and now a de-facto standard for secure communication over the internet, SSL is implemented by all secure web servers and browsers like Internet Explorer, Firefox, Safari, Opera etc.

Where SSL is used

The widest use of the SSL protocol is done in browsers. It will secure the browser of any site on the internet, for example: for login pages, or online banking, or any other financial site. Accessing any site starting with https://  in the address bar of the browser initiates the SSL connection between the browser and the SSL server,  e.g. https://www.paypal.com in your address bar will establish a secure SSL connection between the browser and the web server of www.paypal.com. Apart from this SSL can be used in FTP or any other application layer protocols. SFTP implements SSL for FTP.
