The server decodes the request and maps the virtual path to a real one, which should match an existing file. How Do Computer Servers Work? ServerWatch -- Everything Servers: Virtualization, Blades, Power & Cooling -- Technology News, Trends and Analysis for Server Admins. Top 10 Server Technology Trends for the New Decade. Mobility and agility are the two key concepts for the new decade of computing innovation. At the epicenter of this new enabled computing trend is cloud computing. Virtualization and its highly scaled big brother, cloud computing, will change our technology-centered lives forever.
These technologies will enable us to do more; more communicating, more learning, more global business and more computing with less — less money, less hardware, less data loss and less hassle. During this decade, everything you do in the way of technology will move to the data center, whether it's an on-premises data center or a remote cloud architecture data center thousands of miles away. 1. Mobile Computing Ten trends for the next 10 years. As more workers report to their virtual offices from remote locations, computer manufacturers must supply this new breed of on-the-go worker with sturdier products loaded with the ability to connect to, and use, any available type of Internet connectivity. 2. 3. 4. 5. 6.
