Healthy skin doesn't have to come from an expensive medical process. In fact, simply adding an exfoliating product to your skin care routine can bring an end to dull, flaky skin and help you put your best face forward. Exfoliating removes dead cells from the uppermost layer of skin to reveal the fresher, younger skin underneath. Soaps and cleansers remove dirt and oil from the skin, but soap can't remove all of the skin's dead cells on its own -- that's where exfoliation comes in. Exfoliating tools, like gloves and loofahs, are one option for physical exfoliation. Exfoliating soaps allow you to both cleanse and exfoliate your skin at the same time. Many soaps are made with natural ingredients such as oatmeal, salt, sugar or finely ground seeds. Products that contain chemical exfoliants, such as alpha-hydroxy acids or salicylic acid, should be used less frequently. Although they effectively exfoliate skin, they can also cause dryness and irritation. Exfoliation can help your skin appear younger and brighter -- as long as you don't overdo it.

Read on to learn about exfoliation methods. Dead cells that have been on the surface of your skin are also duller and dryer than the newer cells underneath. Hot water can be irritating and overdrying. Apply your cleanser or scrub, and use your fingers or your exfoliating tool to rub gently in a circular motion. This circular motion will cause the soap to lather and will work the particles or acids in exfoliating soaps deeper into your skin. When you're done scrubbing, rinse your skin thoroughly and apply a moisturizer. Don't scrub on a daily basis unless you have extremely oily skin. Also, take care to not exfoliate too hard or too often. For more information on exfoliating, visit the Web sites on the next page. If your skin is sensitive, cleansers with microbeads can both remove dirt and buff away dead cells without drying your skin. If you have normal skin, experts recommend using biological ingredients such as loofah and seed particles to exfoliate your skin. Is the sodium lauryl sulfate in my shampoo killing me?

When Larry Page and Sergey Brin began work on a project called BackRub, they probably didn't envision the enormous corporation that would grow out of their early efforts. This project evolved into Google, a juggernaut of a company that competes on a global scale with other mega corporations. While the company has products ranging from Web-based e-mail to collaborative office applications, its corporate mission has remained the same. Google's search engine is the oldest and likely most famous tool in the company's arsenal. But the engineers at Google view organizing the world's information as a job too complex for just a search engine. The company designs tools and services that relate to its mission, sometimes in ways that aren't obvious at first glance. One major focus for the company is cloud computing. Companies like Apple and Microsoft offer products that either directly involve cloud computing services or rely on them in some way.

Amazon, the online retail giant, has a thriving cloud storage business. That doesn't mean Amazon has a warehouse filled with fluffy, white clouds. It means the company rents out storage space within its massive data centers. If you are running a company that wants to offer a Web site or service to customers, you may consider using a company like Amazon to host your data. Google also has a reputation for building enormous data centers. In The Dalles, Ore., Google has a data center built next to the Columbia River. Each building in this data center is about the size of a football field. The location has many features that make it attractive for a data center: It's near hydroelectric dams, which makes power accessible and economical. These huge facilities are necessary for Google to carry out its corporate mission. Not only must the company search and index the world's information on the Web but it also has to provide the power for a growing network of cloud computing services.

Now, let's take a look at exactly what cloud computing means. What is Cloud Computing? Cloud computing is a popular buzz term in technology circles. The phrase has a vague sound to it. What exactly is cloud computing? At its most basic level, cloud computing is a model for remote computer access. The idea is simple: You use your computer and an Internet connection to make contact with a remote server. This server, which is really just a computer, runs applications using its hardware. You're able to influence the application by executing commands through a Web browser or other user interface. But the remote server is doing all the heavy lifting. One reason is that it lets you access applications your own computer might not be able to execute. Your computer only has to run a Web browser or simple user interface. In most cloud computing applications, this client-side program places minimal demands on your machine's resources. That means you can take advantage of a variety of programs and services without having to continually invest in the fastest computers.
