The Traditional On-Premises Model #

The traditional approach of building and running on-premises applications has always been complex, expensive, and risky. Building your own solution has never offered any guarantee of success. Each application was designed to meet specific business requirements. Each solution required a specific set of hardware, an operating system, a database, often a middleware package, email and web servers, etc. Once the hardware and software environment was created, a team of developers had to navigate complex programming development platforms to build their applications. Additionally, a team of network, database, and system management experts was needed to keep everything up and running. Inevitably, a business requirement would force the developers to make a change to the application. The changed application then required new test cycles before being distributed. Large companies often needed specialized facilities to house their data centers. Enormous amounts of electricity also were needed to power the servers as well as to keep the systems cool. Finally, all of this required use of fail-over sites to mirror the data center so that information could be replicated in case of a disaster. Old days, old ways—now, let’s fly into the silver lining of todays cloud.
