The term colocation is used in the computer industry to describe the use of a specialist data centre that is run independently and hosts file servers for a number of different companies.

Independent data centres of this type are also called colocation centres, 'colos' for short, or the more descriptive 'carrier hotels'. These data centres are set up by specialist firms with expertise in information technology, to serve the needs of numerous clients. That way, the clients can simply outsource this service to a colocation supplier and let them take care of everything for them. This is much more sensible that trying to do it yourself, for a number of reasons.

Cost is an important consideration. If you were to invest in a state of the art data infrastructure yourself, you would have to spend more than a specialist supplier who could broker wholesale deals for IT services on your behalf which could save you a great deal of money in the long run.

Economies of scale come into play too. A professional colocation supplier will have invested in large, industrial-strength systems which are bigger and more powerful that any individual firm would ever need. This means that you are getting the benefit of a more powerful system, and you can buy in to it for a low relative cost.

Time is another element of the equation. Why re-invent the wheel yourself, when a colocation supplier has data solutions at their fingertips. These would include solutions to your immediate requirements, and also remedies to any future IT problems that you don't even know you have yet!

Access to expertise is a further advantage of using colocation.
You will have the benefit of advice and support from experts in the field who have experience of looking after many different types of requirement across numerous different industries. And this access will usually be arranged on a shift system, so that you can always speak to someone at any time of the day or night on any day of the week, including weekends and public holidays like Christmas and New Year's Day.

In addition to gaining access to IT systems for networks, servers and data storage, colocation firms will also give clients the ability to interconnect with numerous telecommunications suppliers and providers of other network services. Because colocation firms look after many kinds of IT need across a wide range of industrial sectors, they will be able to suggest packages of services after doing a survey of your particular needs and current situation.

And because the colocation firm is an expert in their field, that means that the package they propose for you will have the capability of being adapted as the needs of your business change. Upgrades can be discussed and arranged quickly with people you trust, who know your business. This means that clients can then focus on their core business, without having to divert from what they do best and try and become a mini-expert on IT data systems themselves.

An SSL, or Secure Socket Layer, is technology that has been developed that allows web browsers and web servers to communicate over a secured connection.

The system uses cryptography that uses two keys to encrypt data  a public key known to everyone and a private or secret key known only to the recipient of the message. It’s a way to encrypt data, like credit cards numbers (as well other personally identifiable information), which prevents the "bad guys" from stealing your information for malicious intent.

The recently introduced SSL v3 improved upon SSL v2 by adding SHA-1 based ciphers, and support for certificate authentication. SSL v2 was known to be flawed in a variety of ways. Identical cryptographic keys are used for message authentication and encryption. The older version did not have any protection for the handshake, meaning a Man-in-the-middle downgrade attack could go undetected.

SSL has recently been succeeded by Transport Layer Security (TLS), which is based on SSL and is included as part of both the Microsoft and Netscape browsers and most Web server products. SSL uses the public-and-private key encryption system from RSA, which also includes the use of a digital certificate.

SSL-enabled client software can use standard techniques of public-key cryptography to check that a server's certificate and public ID are valid and have been issued by a certificate authority (CA) listed in the client's list of trusted CAs. Client authentication allows a server to confirm a user's identity. It’s a way to assure a client that they are dealing with the real server they intended to connect to. It can prevent any unauthorized clients from connecting to the server, preventing anyone from meddling with data going to or coming from the server.

From the very beginning SSL was designed to provide security between client and server, and to avoid any kind of 3-way man-in-the-middle attack.

Conceptually it’s quite simple: it negotiates the cryptography algorithms and keys between two sides of a communication, and establishes an encrypted tunnel through which other protocols (like HTTP) can be transported. It can also be easily passed through firewalls and proxies, as well as through NAT (Network Address Translation) without issues.

'Fully integrated' is a term used to describes websites that are progressive enough to include virtually every form of online media in their web presence.

If you look at sites like Yahoo, Forbes and virtually any of the major television network sites you can gain some idea of what I am taking about.

These sites contain either news of blog information. They also contain original video streaming sources and audio streams including podcasts. These sites tend to subscribe to the idea that the web user wants it all and should be able to find it all when they visit the business site.

A fully integrated site will often use flash or other animated or moving text. The interesting dynamic is that the best of these sites understand navigation and ease of use remains a critical concern for guests.

Forbes, for example is highly adept at slideshow type presentations on a multitude of topics. It could be top selling cars, entertainers, vacation hot spots, etc. These slideshows are optimized for search engines and are easy to breeze through.

It seems as if a site like this has the potential to garner some of the same consumers of media that have been courted mostly by network television or traditional newsprint.

Most fully integrated sites did not start off that way. In most cases they worked through issues they could easily address and then added features as their knowledge and confidence grew in relation to the their site development skills.

That's something I have always suggested. Do the best you can at developing a site with the most comprehensive development techniques at your disposal. That doesn't mean you have to have a fully integrated site in order to conduct business, but it does mean that you do not simply wipe your brow, release a sigh and suggest to yourself that your work is finished.

The truth is there are more skills in online web development that are being released than ever before. More programs are working with each other allowing a new robust platform for online use. The role of online web development is an ever changing - ever growing function in relation to how you manage your site and in the use of the most effective marketing tools available.

Many sites will develop an internal compass that provides the date they want to upgrade the website to include new functions. In essence they treat their website like software developers treat upgrades. Some will even go so far as to indicate their website has gone from version 1.0 to version 1.1 or 1.5. The idea is to challenge their own thinking in relation to developing a website even after the website has been launched.

This has the potential of keeping visitors interested in finding out what improvements you will come up with next.

Perhaps the greatest development rule of thumb is that you should always strive to be more integrated by attempting to meet the real and perceived expectations of your site visitors. This mentality will always give you a new goal line in your race for the perfect business.
