Moving from shared hosting to dedicated

Why you should consider dedicated server hosting instead of shared. You can read a brief overview about dedicated servers here. This article will demonstrate in a more detailed approach why and when you will need to move on to a dedicated server from a shared hosting environment like Cpanel, Plesk, Directadmin etc.

Domain name and DNS FAQ

2. What is domain registration?

Basically, domain registration is limited-time ownership. You register a domain (something.com or something.org etc.) in order to claim ownership of it for a specified length of time, anywhere from 1 to 10 years. The "Registrant" of a domain is the actual legal owner of the domain name until the registration period expires.

Network bonding on Linux

This guide cover almost any version of Ubuntu (tested with 7.10. 8.04,8.10 and 9.04).
Bonding is creation of a single bonded interface by combining two or more Ethernet cards into one. This is called bond0 bond1 and so on.
This helps in high availability and performance improvement.
For example you can have 4 Gigabit Ethernet cards combined into one and from that (4Gigabit in total) to server a file server, a Samba. This will improve a lot the performance of your file server as it is obvious.

Walking the Filesystem Using the File Find Module

Perl comes with a module called File::Find that allows Perl to emulate the Unix find command. The easiest way to begin using this module is to use the find2perl command to generate prototypical Perl code for you. find2perl is not always easy to use on non-Unix Perl ports. For example, MacOS users either will need Macintosh Programmer's Workshop (MPW) to run it, or should modify the code to take @ARGV from a dialog box.

PKI…Can we trust anyone out there?

PKI stands for Public Key Infrastructure, the set of hardware, software, people, policies and procedures needs to create, manage, store, distribute and revoke Public Key Certificates based on public-key cryptography. Public key cryptography reduced the number of keys needed for practical secure communication over an insecure channel. Strong authentication in ITU-T Recommendation X.509 defines a framework for the provision of authentication services under a central control paradigm represented by a Directory.

Linux cluster

A computer cluster is a group of linked computers, working together closely so that in many respects they form a single computer. The components of a cluster are commonly, but not always, connected to each other through fast local area networks. Clusters are usually deployed to improve performance and/or availability over that provided by a single computer, while typically being much more cost-effective than single computers of comparable speed or availability

Architecture of the Linux Enterprise Cluster

I've introduced a definition of the term cluster that I will use throughout this article as a logical model for understanding how to build one. The definition I've provided in this introduction (the four basic properties of a Linux Enterprise Cluster) is the foundation upon which the ideas in this article are built. After I've introduced the methods for implementing these ideas. If you don't have any experience with Linux you will probably want to start reading about the basic components of the GNU/Linux operating system that make building a Linux Enterprise Cluster possible.

Learn about virtualization

A virtual private server (VPS, also referred to as Virtual Dedicated Server or VDS) is a method of partitioning a physical server computer into multiple servers such that each has the appearance and capabilities of running on its own dedicated machine.
Each virtual server can run its own full-fledged operating system, and each server can be independently rebooted.
The practice of partitioning a single server so that it appears as multiple servers has long been common practice in mainframe computers, but has seen a resurgence lately with the development of virtualization software and technologies for other architectures.
