Companies that have a data centre or computer centre go to great lengths and make use of the most advanced technological equipment to ensure that they would always have high availability and uninterrupted power supply (Unterbrechungsfreie Stromversorgung). These companies would include those who have websites and conduct business online. High availability is an important system design protocol and associated implementation that ensures a certain absolute degree of operational continuity during a given measurement period. On the other hand, a source of uninterrupted power is also essential to maintain continuous operations.

These companies usually apply certain computer centre (Planung Rechenzentrum) design elements to the physical layout of their data center. They make sure that they have efficient fire protection and prevention programs and systems which are readily available in the event of an emergency. These should not only be a part of their system operations but should also be reflected in the active and passive design elements of their data center. They also get as much backup power sources as possible including an uninterruptible power supply (UPS) or a generator.  Aside from these, they install an efficient air conditioning system that would have the ability to maintain the ambient temperature of the data center, which could otherwise be too elevated, possibly causing damage and other problems. To make sure that the availability of the computers and information will never be lost, they also employ duplicate systems. Their data centers also have raised floor panels, providing ample space for cables and to help in the effective circulation of air. Another important factor that they consider for the physical design layout of their data center would be having sufficient physical security measures including the installation of video surveillance, restricting access to certain areas and hiring full-time security personnel. These can all help in maintaining a secure environment for company data.
Along with creating and maintaining an ideal physical environment, ensuring high availability and having a power supply that can never be interrupted should always be the top priorities of any company especially one that does business online such as social networking sites and those that offer home page web design services.
