However, practice has shown that these very topics can be of great importance. Because the higher the dependency on the cloud provider and the more negligent the provision made for the problem, the more painful the damage caused by disruptions or even failures. The attitude pro or against cloud differs from country to country. Germany has long been more conservative in cloud services than, for example, the US. In the meantime, corresponding services are almost indispensable in everyday life in this country too. Basically, you can distinguish between three service models:
Infrastructure-as-a-Service (IaaS): With this model, the customer gets the computing power, the memory or the network offered as a service. It can scale freely and configure an ideal infrastructure to install servers and applications. Best known in this area may be Amazon and Microsoft, but also Hetzner, Strato and other German providers provide these services.
Platform-as-a-Service (PaaS): This service model provides flexibly configurable and scalable systems. The customer gets a complete system of hardware and operating system. These cloud services are often found in the form of managed Exchange servers, ERP systems, or file share systems, right through to the Web page building block system.
Software as a Service (SaaS): This model provides a variety of applications for use from the cloud; For example, Office365 from Microsoft, Google Docs, Google Hangout or various graphics applications from Adobe are known.
Optimize availability and effort
The major software vendors such as Microsoft, Apple, Adobe, etc. are currently focusing their offerings heavily on the cloud and offer their licenses in the cloud usually cheaper than for the local installation; or they do not allow any alternative. This should make customers more loyal to the manufacturer. Middlemen become superfluous, profits rise. IT distributors have also recognized the trend in PaaS and IaaS and are providing smaller IT system houses with cloud services, which they then pass on to their end customers. This makes every IT system house a data center operator and can be more professional on the market.The benefits of cloud services are obvious. Aspects such as cost transparency, availability, and ongoing software updates help minimize IT risks and reduce internal IT costs. Large investments in the field of IT infrastructures are unnecessary.
IT security benefits from automated software updates within the cloud services, and the security standard is significantly enhanced by redundancy and fire protection; Out-of-date software vulnerabilities do not even arise. Cloud services enable companies to quickly respond to changes in the market and implement new IT solutions for business needs. End users can use IT services, such as the Managed Workplace, that are typically deployed only in large companies.
