Cloud or on-premise - the agony of choice

The competition between the cloud and the company's own data center is far from over. In addition, edge computing is already being traded as a potential successor to the cloud.

IT trends such as Big Data, IoT and Industry 4.0 are continuously increasing the demand for data and computing power. Basically, this can be achieved within the company itself or via an external service provider, i.e. in the cloud.
The "Cloud Monitor 2018" from management consultancy KPMG shows a slight increase in cloud acceptance, even among sceptical German companies. Two out of three companies with at least 20 employees are already using the cloud, 1 percent more than in the previous year. They are increasingly positive about data security in the cloud, and there is potential for improvement above all in terms of IT administration effort and implementation times for new cloud applications.
But despite the apparent triumph of the cloud, on-premise data centers are still justified. In some ways, they are still the better choice. A glance at the topic of high availability, for example, shows that 69 percent of companies have been unable to access their cloud applications at least temporarily over the past twelve months.
In addition, going into the cloud is (almost) a journey with no return. The way back into one's own corporate environment is like driving on a one-way street in the wrong direction: possible, but associated with great risks, costs and effort.

Omnipresent Cloud

A classic public cloud solution is based on the principle of Software as a Service (SaaS). All data is stored on external servers from specialized providers. As a result, neither an in-house data center nor trained IT specialists are required. That's why there are hardly any industries left that resist the lure call of the cloud. "Cloud services are used in all areas, such as information technology and telecommunications, transportation and retail," said Christian Gehring, Director Solution Architects at VMware. The size of the company plays hardly any role. "Both small and medium-sized German companies as well as large global companies have discovered the cloud.
Of course, there are good reasons why the cloud has a certain fascination for IT decision-makers. "In most cases, the cloud comes into companies through additional projects or additional resource requirements because it is more agile and can be switched on faster than traditional IT procurement. It then complements the existing on-premise infrastructure, extends it or forms the backup," explains Henrik Hasenkamp, CEO of the Cologne-based IaaS and PaaS provider gridscale.

In the rarest of cases, the cloud completely replaces your own data center. There are good reasons for this as well: "On the one hand, the servers purchased are of financial value to the company at least until they are fully depreciated, on the other hand, certain regulations regarding data storage and security make on-premise solutions indispensable in some industries.
According to Carlo Pacifico, VP DACH of application performance management provider New Relic, cloud laggards are primarily long-established companies: "Traditional companies such as established financial service providers are often still at the back of the innovation wave due to their corporate culture and complex organizational structure.
