Cloud computing providers provide businesses with extensible, flexible, reliable and cost-effective platforms for cloud services. Many companies are already successfully deploying cloud applications. Others are currently in the decision-making phase, evaluating the costs and benefits of moving their entire IT infrastructure to cloud computing. Basically, it can be said that the use of a cloud offers high cost savings compared to an internal IT infrastructure.
In the beginning, high initial investments in hardware have to be made and in the course of time further costs for expansions have to be incurred. In addition, the infrastructure must be maintained regularly. Another disadvantage is the maximum server utilization of only 20%.
Savings would be possible through optimal use of all resources. However, this is not really feasible in reality.
This would require a reliable network connection including redundant hardware as well as transit connections and physical (backup) lines between the individual data centers. In addition to a backup, a concept for a possible worst-case scenario would also have to be available.
Security measures are cost-intensive in order to meet certain standards.
The provisioning process is often very lengthy. One solution would be to oversize the infrastructure. However, this leads to suboptimal use and thus to unnecessary costs.
The employees concerned must be on permanent standby to ensure smooth operations. In addition, regular maintenance work, scaling in the form of renegotiations and purchases, and general administration are also required.
Der Betrieb und die regelmäßige Wartung der aktuellen Infrastruktur ist essenziell, kosten- und zeitaufwändig, zusätzlich muss die kontinuierliche Weiterbildung von Mitarbeitern gewährleistet sein.
Cuts in IT budgets prevent the expansion of the infrastructure according to the desired and actually needed needs and thus the realization of projects.
