First, you need to choose your RAID implementation. Personally, I prefer to use RAID 5 on Amazon EC2, combined with LVM2.
For setting a RAID 5 up and running you will need to raise at least 3 EBS volumes and attach them to your instance (let’s say: sdb1, sdb2, sbd3). Read more »
Porting Debian to Amazon EC2 for HPC
Few months ago, I was challenged to build a High Performance Computing (HPC) instance on Amazon EC2 and the first thing that came in my mind was: which Linux distribution would fit on such requirements.
I must confess I’m pretty much adept to Debian, but I was forced to be unbiased and start researching for better options for achieving my goal. Also because the environment I was going to port was already running Debian, but the application’s traffic growth was increasing at high speed and it seemed something was going on with that server.

Debian / Ubuntu Apache SSL Configuration
Hey you are planning to start a e-commerce website, then you must know about SSL without which no one will trust your website as a safe place to use their cards…
What is SSL?
SSL (Secure Socket Layer) is a protocol used for secure data transfer. This is done by using private keys and certificates. A private key is used to encrypt the data which you are sending and the server can only decrypt this data with the private key available with it, A certificate is used to authentic yourself before proceeding.
So we need two things to make our website secure for online transactions. In this article i will explain how to generate a private key, certificate request with open-ssl and apache, get certificate from CA (Certificate Authority), configure your server to respond for ssl requests.
Different types of certificates
Before going to configuration I will explain about the different types of certificates available in the market and when to use which. The certificates are mainly divided into High Assurance and Low Assurance, High assurance is needed for sites dealing with financial transactions, low assurance is needed for internal corporate networks or small websites and mainly used for secure login to site and sending sensitive documents securely.
Remember every byte you are sending through http protocol means non-ssl layer can be seen or accessed by anyone.
Configuration:
I used Apache 2, Debian Linux, Openssl for this configuration.
First step is to install Apache:
Go to console mode Read more »
