Cloud providers are companies that provide IT environments such as managed private clouds or public clouds. Here, the scalable resources can then be bundled in a network and combined in pools. Customers and users can then access them. Such providers can also offer an online service.

The reasons why a cloud provider or provider should be used? 

Such providers offer the customers or benefits partly Cloud computing service on the areas of infrastructure, software or platforms. 
In the area of infrastructure, the offer includes, for example, servers, storage, networks and virtualisation solutions.  
As far as platforms are concerned, these are tools that are used to provide and develop applications. These include, for example, runtime environments, operating systems and middleware. 
In the software sector, these are applications that can be used immediately. These include, for example, standard and customised applications. 

Difference between Public Cloud Provider and Managed Private Cloud 

Public solutions 

These providers virtualise customers' or users' platforms, infrastructure and other applications using their own hardware, and then package this in Data Lakes into customised management and automation software, which is then transmitted to the customer or user via the Internet. 

Managed Private Cloud 

Here, the customer or user is provided with a private cloud, which, however, is not managed by the customer or user himself. This is an option for users or customers who are understaffed in the IT department and not equipped with sufficiently qualified IT specialists. 

Which providers fit a customer or user here?

With public cloud provider solutions, the services and platforms are usually provided according to hours of use or bytes. Here, depending on usage, there can be sharp changes in costs. With large public providers, access is usually possible regardless of location (worldwide). Regional providers, on the other hand, increasingly ensure compliance with government regulations. The customer or user usually concludes a standard support contract here and thus support is available for software changes, security measures and problem solutions. 
With the managed private cloud solution, fixed contracts are usually concluded, which then only increase if the turnover of customers or users increases drastically. The advantage here is that the support staff are located near the data centre and can therefore intervene quickly.
