Hybrid Cloud: Technologies and use cases for companies

from | 13 April 2023 | Basics

Cloud technology has developed rapidly in recent years. The hybrid cloud in particular is becoming increasingly popular for companies that want to benefit from both public and private cloud structures. By using a functional hybrid cloud architecture, modern companies can optimise their resource allocation and thus act more flexibly. But how exactly does such a hybrid cloud infrastructure work, what advantages and disadvantages does it bring with it and what view into the future can be ventured with this technology? This article aims to clarify open questions and provide clarity.

What is a Hybrid Cloud?

Hybrid Cloud refers to the Combination of public and private cloud infrastructure. Thereby applications and Data be moved back and forth between the different cloud models. Companies can thus benefit from the advantages of the public cloud, such as Scalability and flexibilitywithout exposing themselves to potential risks such as lack of control and security. At the same time, they can take advantage of the benefits of the private cloud, such as increased Security and controlwithout having to forego the flexibility and scalability of the public cloud.

How does a hybrid cloud work?

A hybrid cloud infrastructure consists of a network of private and public cloud systems, which are connected via a common technology platform are connected to each other. An important aspect of a hybrid cloud infrastructure is the ability to connect as needed, Move applications and data between cloud models. Private clouds, public clouds and local IT infrastructures can be linked together. By integrating multiple cloud models, companies can benefit from the advantages of each cloud technology while minimising the disadvantages. The different Cloud architectures are produced with the help of Programming interfaces (APIs) and other technologies with each other, so that uniform applications and Data management arise.

What are the advantages and disadvantages of a hybrid cloud?

Advantages of the Hybrid Cloud:

  • FlexibilityCompanies can access different resources at any time and adapt their infrastructure according to business requirements.
  • ScalabilityThe hybrid cloud enables flexible adaptation of resources to respond to changes in the business environment.
  • Cost saving: Using public cloud services can be cost-effective for businesses, especially for short-term projects or for running applications with fluctuating demand.
  • Security: By using a private cloud for sensitive data and applications and a public cloud for non-critical data, companies can take advantage of both cloud architectures without compromising security.

Disadvantages of the Hybrid Cloud:

  • Complexity: Integrating multiple cloud architectures can be a complex task that requires specialised skills and expertise.
  • Dependence on third party suppliers: The use of public cloud services means that companies are dependent on external service providers, which can lead to dependencies and possible security risks.
  • Data security: The use of public cloud services can lead to data security and privacy concerns as the data is stored outside the direct control of the company.

What are the differences to other cloud models?

Hybrid Cloud vs. Public Cloud

The public cloud is a cloud architecture in which IT resources and services are provided over the internet by a third-party provider. The advantages of the public cloud are scalability, flexibility and cost efficiency. Companies can adapt IT resources as needed and do not have to build their own IT infrastructure. The disadvantage is that the data is stored outside the company and control over the infrastructure is transferred to the third-party provider.

Essentially, the difference between hybrid cloud and public cloud is that the hybrid cloud is a combination of public and private cloud services, while the public cloud is solely run by a Cloud provider provided and shared by many different clients.

Hybrid Cloud vs. Private Cloud

Unlike the public cloud, where resources are public and can be used by anyone, in a private cloud only certain people or organisations are authorised to access the resources. A private cloud can either be operated by a company itself or by a third-party provider. In the first case, it is often referred to as an on-premises cloud, as it is installed on the company's own servers. In the second case, it is referred to as a hosted private cloud, which is managed by an external provider.

One advantage of the private cloud is that it offers more control and security, as it can only be used by authorised persons or organisations. In addition, specific requirements and needs of the company can be taken into account and implemented. However, operating and maintaining a private cloud is often more expensive than using a public cloud. In addition, it can be more difficult to find a scalable solution that meets the company's requirements.

In contrast, the hybrid cloud combines elements of both public and private cloud infrastructure. For example, highly confidential data or applications can be hosted within the private cloud, while less confidential applications or data are provided in the public cloud. By combining the two cloud models, the hybrid cloud enables more flexible and cost-effective use of cloud computing resources while maintaining control and security of data and applications.

Hybrid Cloud vs. Multi-Cloud

The hybrid cloud and the multi-cloud are two different approaches in the field of the Cloud computing.

A multi-cloud architecture combines several cloud environments with each other, such as public clouds, private clouds and/or on-premises clouds. This offers companies the opportunity to take advantage of different cloud models and distribute their resources accordingly. A multi-cloud can also help minimise downtime, as a disruption in one cloud environment does not necessarily impact all other environments.

The hybrid cloud is a combination of a private cloud and a public cloud environment that can work together and exchange data and applications between the two environments. The private cloud is usually used for business-critical or particularly sensitive data and applications, while the public cloud is used for less critical applications or data.

In summary, the hybrid cloud is a combination of public and private clouds, while the multi-cloud involves the use of multiple cloud platforms from different providers.

What are the application examples for the hybrid cloud?

A hybrid cloud architecture is used by companies from various industries. An example from the Automotive industry is the connection of production facilities and the central IT infrastructure. Another example from the Healthcare is the linking of patient data from different hospitals to ensure comprehensive, location-independent care. Also in the Retail the hybrid cloud can be used to E-commerce platforms and stationary points of sale with each other. In the Financial sector the hybrid cloud can be used to securely store sensitive data within an organisation while outsourcing data processing to public cloud platforms.

What are the benefits and challenges of implementation?

The integration of hybrid cloud solutions offers companies numerous advantages. Through the combination of private and public cloud, a Flexible and scalable IT infrastructure can be created that can be adapted to the individual needs of the company. The hybrid cloud also makes it possible, Reduce costsas only the necessary resources need to be rented or purchased.

However, when it comes to implementation, there are also Challenges, like the Integration of the various cloud systems and the Ensuring the Data security. Thorough planning and careful management are needed to ensure successful integration.

How secure is the hybrid cloud?

Security is a key issue when using cloud solutions. In the hybrid cloud, companies must ensure that their data and applications are securely stored and transferred in both the private and public cloud. To ensure this, companies must take appropriate security measures, such as the encryption of data and the use of firewall systems. It is also important that the company's employees are trained on the risks and best practices when dealing with hybrid cloud solutions.
