In modern companies, the question is often asked: is it still economically and technically sensible to have your own cloud computing server? Server or. to run a server landscape?
Maintaining and managing a server often incurs considerable costs, and technical support and maintenance should not be underestimated. With increasing server requirements come additional downtime due to expansions such as RAM increases, enlargement of hard disk storage and similar technical performance enhancements.
You can leave this part of the responsibility to us.
We make sure your IT landscape runs smoothly.
In the age of optimization, it is inevitable to think about the use and conservation of resources.
One bought for the current time Server landscape is no longer valid within a short time window. following is the need for a Server change. In some cases it may be advisable to have a performance buffer upwards to cover increasing IT demand and increased IT performance. These factors should be considered when choosing an in-house solution. To avoid the expense one can rent space in a data center. Here you can adjust the performance, depending on your needs. This option is called Cloud Computing, that means you just place your servers in a data center. A change to another data center is possible at any time without complications. There is no connection between hardware and the virtual server.
The Inhouse solution Is the, to date, still the most common variant of a server concept. Here you often find one to X servers in the basement, a storage room, in the closet or in other non-optimized locations in the office. In this server variant all costs for Backup, their backup, data storage and all the surrounding hardware and software necessary to bear directly. A technician is needed on site in case of a more severe outage.
The Server system should report their current state via monitoring so that it can be evaluated. In the event of an error, and depending on the severity of the error, action is required more quickly.
Virtual or physical servers?
If you build a new system today, the question often remains whether to install the server operating system on the hardware host server itself or to use virtualization software such as VM Ware, XEN or Hyper-V. In individual cases, a direct installation may make sense, for example, for specialized Database servers, Graphics applications or applications that require direct access to special server components.
The virtual system has three major advantages over the physical installation. The first thing to mention here is the simple and optimized backup option for virtual machines, during operation. The second is the snapshot option. One can define different test scenarios at different times, modify them, discard them or even insert them into the live situation. This function offers endless options. The third one is the migration of a virtual machine, in running state, to another server. This brings enormous advantages in the maintenance situation. Free up space to upgrade, optimize or even repair the physical servers. The normal PC user will not notice anything about this process.
