Web Hosting - Changing Web Hosts, Pitfalls and Planning At some point, nearly everyone finds it necessary to change web hosts. It may be just a migration to another server, or it may be changing web hosting companies entirely. Either way, the process is fraught with potential dangers. But there are ways to minimize the odds of problems and maximize your changes of a smooth migration. Plan, plan, plan. Make a very detailed list of everything that is on your current system. Review what is static and what changes frequently. Note any tailoring done to software and files. Be prepared to remake them if the systems aren't transferred properly or can't be restored. Keep careful track of all old and new names, IP addresses and other information needed to make the migration. Backup and Test Backup everything on your system yourself, whenever possible. Web hosting companies typically offer that as a service, but the staff and/or software are often less than par. Often backups appear to go well, but they're rarely tested by restoring to a spare server. When the time comes that they're needed, they sometimes don't work. Do a dry run, if you can. Restore the system to its new location and make any needed changes. If you have the host name and or IP address buried in files, make sure it gets changed. This is often true of databases. SQL Server on Windows, for example, picks up the host name during installation. Moving a single database, or even multiple ones, to a new server is straightforward using in-built utilities or commercial backup/restore software. But moving certain system-related information may require changing the host name stored inside the master database. Similar considerations apply to web servers and other components. Accept Some Downtime Be prepared for some downtime. Very few systems can be picked up, moved to another place, then brought online with zero downtime. Doing so is possible, in fact it's common. But in such scenarios high-powered professionals use state-of-the-art tools to make the transition seamless. Most staff at web hosting companies don't have the skills or the resources to pull it off. Prepare for Name Changes One aspect of moving to a new host can bedevil the most skilled professionals: changing domain names and or domain name/IP address combinations. When you type a URL into your browser, or click on one, that name is used because it's easier for people to remember. www.yahoo.com is a lot easier to remember than 209.131.36.158. Yet the name and or name/IP address combination can (and does) change. Still, specialized servers called DNS (Domain Name System) servers have to keep track of them. And there are a lot of them. There may be only two (rarely) or there may be a dozen or more DNS servers between your visitors' browsers/computers and your web host. Every system along the chain has to keep track of who is who. When a name/IP address changes, that pair has to be communicated to everyone along the chain, and that takes time. In the meantime, it's possible for one visitor to find you at the new place, while another will be pointing to the old one. Some amount of downtime will usually occur while everything gets back in sync. The Little Gotchas But even apart from name and IP address changes, there are a hundred little things that can, and often do, go wrong. That's not a disaster. It's just the normal hurdles that arise when changing something as complicated as a web site and the associated systems that underlie it. Gather Tools and Support Having an FTP program that you're familiar with will help facilitate the change. That will allow you to quickly move files from one place to the next to do your part to get the system ready to go or make repairs. Making the effort to get to know, and become friendly with, support staff at the new site can be a huge benefit. They may be more willing to address your problem before the dozen others they have to deal with at any given moment. Ok. On your mark. Get ready. Go.

Web Hosting - DNS, How The Internet Keeps Track of Names The way computers communicate is, in a way, very similar to something very familiar: the postal system that delivers letters and packages. Here's how... The Internet is just what the name suggests, a large inter-connected set of networks. But those networks are pointless without the one part that forms what is called their 'end-nodes', otherwise known as computers. Those computers often need to share information because the people who use them want to share information. But, in a system where there are millions of separate computers, how can you enable them all to communicate? One very important feature of that solution is performed by something called DNS, the Domain Name System. Every part of a network that is going to send or receive information is assigned an IP address. That's a numeric identifier that uniquely specifies a particular 'node', such as a computer, a router that directs traffic or other component. They look like this: 209.131.36.158 But those numbers are more difficult for people to remember and work with. They also aren't very attractive from a marketing perspective. So, a naming system was layered on top of some of them, mostly the computers involved, though routers have names, too. But once you have a system that associates a unique IP address to a given name, you need some way of keeping track of all of them. That's carried out by several different pieces of the system: Name Registrars, DNS Servers and other components. The Name Registrars, overseen by IANA (Internet Assigned Numbers Authority) and other international bodies, provide and keep track of domain names. When you register with GoDaddy or any of a hundred other intermediate companies, ultimately that information makes its way into a number of specialized databases stored inside DNS Servers. A DNS Server is the hardware and/or software that tracks and forwards the IP Address/Domain Name pair from one place to the next. In many cases, there are a number of them between your browser and the remote computer you want to share information with. Suppose you request information from, say, Yahoo's site by clicking on a link on their site. DNS resolves (translates) the name of WHO IS making the request and OF WHOM, to addresses, then passes the request through the network to the requested IP address. The requested data is then passed back through the mesh of network components to your computer and displayed in your browser. Whether the communication is between a desktop computer and a server somewhere, or between one server and another, the process is essentially the same. DNS servers translate names into IP addresses and the requests for data are forwarded on. In some cases those DNS servers are part of a specialized network computer whose sole job is to do the translation and forwarding. In other cases the DNS software may reside on a server that also houses a database of general data, or stores email, or performs other functions. But however complicated the chain or the parts, the basic process is simple. Translate the name to an address, just as the postal system does. Whether international or local, your name is associated with an address, and the deliveries are made to the address, then forwarded to a particular name.

Can Job Sharing Boost your Employee Profile? Job sharing is one of the newer occurring work arrangements on the job market. It means that two or more people share one full time position. Most often it is two people that work part time on the same position. This kind of work sharing is a great invention for all parents that want to spend more time with their children or for people that are just not made for a full time job. Job sharing is a flexible job option that shares one person’s responsibilities between two people. So, can job sharing boost your employee profile? Yes, of course is the answer to that. The reasons why job sharing boosts your employee profile are widely spread. Job sharing can bring benefits not only to employees but also to employers and companies. Start by looking at the aspect of sharing your work. If you are sharing a full time position load with another person, pressure is less on you. You still have the same deadline, but the pressure is shared and you can work more efficiently on your work assignments. Less stress makes for a happier more relaxed employee that can tackle the work given to him or her easily. This makes the employee a more balanced person. The possibility to stay at home while still having a chance to be part of a company can further your career and keep your skills up to date and this makes for a well balanced worker. Another reason why job sharing might boost your employee profile is that two people working part time actually can get more work done as one full time employee. Why is that? Well, that is very easy. While the full time employee is very tired in the mid afternoon from his already long day, the person coming in for the second half of the day has had time to relax all morning long and therefore can start with new end fresh energy and thoughts on the shared work. Should the position not be shared in half days, but in each taking a few full days, then the people sharing the position are still more relaxed and motivated. They are able to be with their family, able to rest and regenerate or have fun with some of their favorite hobbies. Psychologists and researchers have long praised the effect that a fun family filled time and enough time to be you and relax can boost your employees’ work input as well as their efficiency. In countries where employees have fewer hours per week and more vacation days a year, the work output per person is in general higher and employees are happy and motivated and stay with their company for long periods of time, if not all the way up to retirement. Additionally, if you have a good amount of time off from work, you are most likely a very motivated and happy employee and your boss and fellow employees will see you as a positive person to be around at the work place. Being a leader and motivator is all that a boss can hope for and therefore, sharing the position can immensely boost your profile. For employers, there is also the consideration of your benefits. Some companies might not pay benefits to part time employees and two part time positions will save you money. In this case, your profile is simply boosted by the fact that your employer saves money. Although in some companies, there are benefits for part-time employees and those can be based on different facts, such as hours worked, full-time benefits and more. Before considering sharing your job and entering the world of part-time employment, make sure that this is exactly what you are looking for in a job. Once you are sharing your position, there might not be a way back to full time, at least not within your own company.
