For whom is cloud computing suitable?

Small businesses and start-ups as well as large global companies benefit from cloud computing. The following aspects and tasks should be considered.

Saving and backing up records

Cost-efficient and secure data protection is crucial to improve one's concepts. By transferring the records to an external cloud storage system, the newly stored items can be accessed at any location.

Streaming image content

In order to stay permanently in contact with one's own target group, the streaming of image content is an important approach of cloud computing. By additionally storing this information, the content remains securely and unambiguously retrievable at any location, even afterwards.

Data set analysis

Data sets can also be analysed effectively and securely to subdivide individual teams. Cloud services in the areas of artificial intelligence and machine learning are ideal for this. In this way, clear insights and information can be generated.

Test and create applications

Extensive testing for new applications can significantly reduce the time required for the associated development. Here, the scalability of cloud systems plays a crucial role in order to test and restructure applications in real time.

Creation of cloudnative applications

API applications and similar links ensure quick and easy adaptation of important data specifications. This makes it easy to comprehensively control communication and make the associated web applications around the cloud constantly accessible.

The many possibilities for application in the field of cloud computing show that each company relies on individual services. This already starts with the use of small cloud storage to make work independent of time and location. The numerous solutions, systems and applications make a good impression at this point and are already superior to the potential of many companies. Nevertheless, it is crucial for companies to open up to the new innovations step by step and to expand existing concepts.


With innovative memory functions, it is easy to Investment costs to be lowereden. The storage and database systems can be aligned individually and precisely based on actual use. This means that there is no longer a need to pay for unused resources, which significantly expands the alignment of professional computing systems in operation.

Scalability also plays a decisive role, which can provide significantly more quality in practical everyday life. This makes it significantly easier to Manage IT resources precisely and benefit from a productive orientation. If more storage space is needed, the systems can be expanded without much effort, increasing computing power.

Another advantage comes from the enormous power and the associated speed. Digital Reservoirs are constantly accessible and ensure smooth access at any location. In practice, this also makes it much easier for companies to access the necessary functions quickly and efficiently and to expand convenience. Lower network latencies and local storage nearby make cloud computing an effective operational solution

Also crucial are security and reliability, which are always guaranteed with the practical systems. Data backup and Emergency restores are possible without any problemsThis means that the concepts comply with all data protection guidelines in most cases. This makes it easy to protect data sets, apps and infrastructures from threats.


Those who like to retrieve their records via an in-house and available system will come up against their limits in cloud computing. Without an active internet connection, the details cannot be retrieved, as these are usually Exclusively digital are stored. With a slow connection, the technology can be used, but the speed then suffers significantly.

In most cases, the records are without a local backup or physical protection. Even if they are basically secured against a crash via several servers, the data cannot be restored afterwards in an exceptional situation. This danger does not exist with local backups, which makes protection much easier.

Also critical is the Dependence on the respective service providers for new cloud systems. The problem is that data availability in the cloud is usually tied to a specific subscription with the respective service provider. Switching to another cloud provider is often difficult and time-consuming, which is why the desired independence is quickly lost.

Different types of cloud services

Numerous solutions and systems have been able to establish themselves around the numerous cloud service providers based on the area of application. These make the Cloud and the associated approaches much more flexible.

IaaS - Infrastructure as a Service

Through the IaaS approach, IT resources such as network capacities as well as computing power are made available digitally. This means that no high-priced hardware products need to be purchased, which significantly simplifies the alignment in daily operations. In concrete terms, this also means cheaper costs for storage usage.

SaaS - Software as a Service

In the SaaS approach, the cloud is at the centre of the action. Here, users have access to a software solution that is directly connected to the cloud. This way, there is no need to buy and install separate programmes. Through cloud computing, the content associated with the software is fully secured and can be accessed from anywhere in the world.

PaaS - Platform as a Service

Around the PaaS approach, an entire platform is available to users for smooth operation. This allows companies to focus optimally on development without having to worry about the technical infrastructure. Joint cooperation within the team is also guaranteed at all times.

WaaS - Workplace as a Service

The WaaS approach is probably the most complex strategy in cloud computing. With this, the user receives a complete workstation that includes both the software and the hardware. In most cases, the concept is based on a concrete lease, which means that the workstation including the cloud connection can be used for a certain period of time.

The numerous service models

Four approaches have emerged around the cloud to offer a suitable and custom-fit solution for every need. The different variants make it much easier to adapt precisely to the existing architecture and to enable full use of the system. Cloud computing offers the following options at this point:

Public Cloud

With the public cloud, a public approach is available in which the storage resources are provided by an external cloud provider via the internet. This provider also takes care of the maintenance and expansion of the cloud and enables compact administration. By paying a monthly sum, users gain access to the cloud system.

Private Cloud

The private cloud is a use that is exclusively intended for the respective company. These cloud systems can be located on-site in the company or be designed on the basis of external service providers. However, the administration takes place exclusively in the private network, which refers to the entire processing.

Hybrid Cloud

A hybrid cloud is a combination of public and private cloud. This makes it possible to increase flexibility and move important data sets between the different areas. Security and structure are always maintained thanks to the pre-existing infrastructure and enable compact use.

Community Cloud

With a community cloud, access is restricted directly to a precisely defined group. This enables, for example, extensive use in specific working groups and groups working on the development of new solutions. This makes the community cloud a private and well-secured approach to universally access all important elements.

An important part of Work 4.0

In the area of Work 4.0, cloud computing solutions are taking on an increasingly important role in order to Drive automation and related approaches effectively. At this point, the cloud is a guarantor for work that is independent of location and time. This also makes it much easier from the user's point of view to integrate new approaches and innovations and to increase sector-independent flexibility through the cloud.

It is precisely this flexibility that is probably the most important approach in cloud computing from which every business can benefit. In conjunction with increasing virtualisation, universal use of the cloud is simplified in order to digitise hardware resources step by step. This is not only space-saving, but also an important approach for greater added value, especially for globally active companies. Around Work 4.0, the cloud is therefore contributing to new innovations.

Wide range of applications in any location

A look at the concrete application in the area of cloud computing shows that almost every industry is dependent on such solutions. Particularly in the enterprise, the cloud now plays a decisive role, as it is essential for an Simplification in terms of time and content provides. From the user's point of view, this makes it much more efficient to access the appropriate systems and benefit from suitable applications. Cloudnative applications have also become indispensable within web development and enable updates in real time.

Cloud computing is also becoming an effective and secure implementation for other service providers in the digital space. This makes the digital workplace much more practical, which in many cases is tied exclusively to a computer and its associated accessories. Developers, programmers, copywriters, consultants and many other professions therefore fall back on the simple and digital systems in everyday life and rely on the comfort of the cloud.

However, the constant digitalisation and the closely related cloud computing are also making themselves felt in many other industries. Transmissions and webinars are also often secured with the cloud and uploaded automatically. The same applies in the legal field and in medicine, with screen transmissions and digital consultations having long since become part of everyday life. In this respect, it is worthwhile to ensure a constantly modern and digital application and to use cloud computing as an effective tool. In this way, flexibility is maintained in every branch.
