Server side computing has been a more affordable and practical technology than its precursor token ring or mainframe. This allows you to have processing power with the end user with the options to upload to a file server. This also allows you to share networks, files, back-ups and remote updates. The internet pushed this concept of sharing information creating newsgroups, blogs, and grid computing which is basically sharing processor utilization among a number of users for a common goal. The Cloud, which is synonymous with the internet, became a common phrase which infers that everybody can keep files and records in a trusted site. So what is the difference between uploading a file to a file server and uploading a file to a cloud? Is there any security once the data goes across the backbone of the internet?

Before we can answer that question we need to understand an older concept of mainframes. All the processing and storage is kept on a mainframe thus leaving the user behind a dumb terminal that can telnet into the system. Mainframes are expensive and if there is trouble either with the network, software, or hardware all of the system tasks come to a halt. With a server/client technology there are many redundant servers with many pathways. Plus processing can still be done with the end user allowing limited productivity. Web applications soon found a home in the local office as well as online communities and became a widely accepted standard. An interesting point about ...

Solution Summary

Originally there were Mainframes which kept all the storage and processing in a local setting. Server/Client technology allowed some storage and processing with the end user allowing greater productivity. Web applications soon found a home in the local office as well as online communities and became a widely accepted standard. This developed the push to share files and applications online. Server side technology allows a greater sense of security but Cloud computing can take a lot liability out of the hands of the business owner. Servers put processing power into the end user and The Cloud put the processing into a worldwide grid computing setting.
