What is cloud computing and its types
Cloud Computing - What's Behind It?
Cloud computing is particularly beneficial for small and medium-sized businesses Big advantages: The acquisition of your own IT infrastructure including servers is complex, costs a lot of money and later requires constant maintenance - this requires specialist staff who also have to be paid. In addition, in the best case scenario, the data center grows with the company, and that doesn't work in the traditional way as needed. Instead, decision-makers then buy new hardware in set cycles and have to estimate future needs. In other words, more resources are usually purchased than are actually needed.
But most companies can no longer operate without a data center. Cloud computing provides a needs-based solution: the acquisition and maintenance of the hardware is then carried out by professionals, and the company itself only requires inexpensive, simple terminals for employees to access the cloud computing services. Professional server farms, as used by cloud providers, are also mostly much better securedthan you could manage on site in your own company: security personnel protect the system against physical access by strangers, specialists secure the servers against digital attacks and fire protection experts ensure that no fire can destroy the data. In addition, many cloud computing providers ensure that all data is backed up.
The cloud computing system also has disadvantages, which is why many companies still shy away from using it. For some companies, the lack of adaptation is a reason to reject the model. With the various cloud providers, you are sometimes more, sometimes less dependent on their configurations. In general, you also make yourself dependent: Should the provider stop operating, you will inevitably face a problem. You also need a strong internet connection. If this is too slow or collapses regularly, employees cannot work effectively with cloud computing.
The biggest concern, however, is likely to be the issue privacy trigger. And in two ways: It is true that the data is backed up on site, but transmission over the Internet always poses a security risk. The other problem with data security often has to do with the location of the data center. While German or European providers generally adhere to local data protection regulations, this is not necessarily the case with other international providers. For example, US companies are required by the Patriot Act to provide data to US authorities upon request. Since companies in cloud computing sometimes place critical data in the hands of third parties, a healthy skepticism on this topic is understandable.
Naturally, cloud computing is not free either: users should therefore think carefully about which capacities they need - and especially when. Companies tend to book more in the context of the cloud than they actually need because the individual costs are so low. But these add up. But that doesn't have to be the case: With many providers, instances can be released again at short notice as soon as they are no longer needed. That saves costs.
