What can you expect in the Cloud?
Cumulus, stratus or cirrus perhaps? Certainly not. Private, public, hybrid and of course multi cloud – that is where our expertise lies. Cloud is not just cloud. Companies have the possibility of adding to or expanding existing cloud architectures. However, what does this mean and how do the types of cloud differ from each other?
Public Cloud - The Simple and Inexpensive Cloud
Everyone knows them, everyone uses them, often even unknowingly: the public cloud. The public cloud describes publicly available software or infrastructure services that comprise a whole range of products and services. The best-known public clouds are Amazon Web Services (AWS), Microsoft Azure Cloud and Google Cloud Platform (GCP). The advantages are obvious. Companies receive cloud services quickly, flexibly and, on top, inexpensively.
Private Cloud - The Individual Cloud
Unlike the public cloud, the private cloud is not publicly accessible. It is operated on a dedicated basis and sometimes hosted internally or externally. The cloud services offered are accessed over an intranet or virtual private network (VPN). Only authorized users can use certain elements of the private cloud, e.g. applications. In this way, the private cloud offers security, control and flexibility. The associated cloud elements can be scaled according to customer-specific requirements, designed specifically and be used efficiently.
Hybrid Cloud - The Combination of Public and Private Cloud
The hybrid cloud is made up of a combination of public and private cloud. This means that public and private services are integrated with each other in a hybrid cloud environment. For example, certain services are run by public providers over the Internet, while data protection-critical applications are operated and processed in the DTS cloud. Such combinations represent particularly sustainable models for cloud use, because they combine the flexibility from the public cloud with the security requirements of the private cloud.
Multi Cloud - The Supreme Discipline
The multi cloud is often confused with the hybrid cloud. However, a major difference exists between the two. With the multi cloud, not only resources from the public and private cloud can be combined with each other, offerings from different cloud service providers can also be used. With the hybrid cloud, two different architectures are used, while the multi-cloud effectively networks and orchestrates the cloud solutions from different providers. The advantages are many. Several services from different service providers can be used in parallel. In addition, the use of these services can be individually adapted. This means that there is less dependency on just one provider and the ability to react to new developments and requirements is faster. The multi cloud guarantees maximum flexibility, availability and data security.
The cloud is a model that allows access to a shared pool of configurable computer resources that can be made available quickly and easily over a network anytime anywhere. However, a very dynamic development can be seen to be taking place within the cloud. "Hybrid, but especially multi, will become increasingly important in the immediate future. However, the effective design and implementation of this cloud brings with it essential requirements:
The more interfaces and processes there are in the cloud strategy, the more sources of error and attack surfaces emerge. In a nutshell: The level of complexity increases, lack of transparency increases, security risks occur more and more and shadow IT can emerge. Not all companies have the expertise and resources required to avoid this, to implement the "cloud" adequately and to make optimal use of the potential. This is exactly where DTS comes into play!
