Hybrid cloud models: everything you need to know

With the constant development of cloud solutions, many companies are faced with the question of which strategy to choose when developing the future system landscape. Thus, decision-makers are faced with the question of whether investing in an on-premise system landscape or a cloud solution is the right choice.

Based on our experience, the hybrid approach is a good choice. In this article, we explain the advantages of a hybrid system landscape to make the decision easier for you.

What is a hybrid cloud - simply explained

In an ever-evolving business world, flexibility and scalability of your IT infrastructure is crucial. That's where hybrid cloud comes in - a groundbreaking technology solution that combines the best of both worlds: The security and control of a private cloud and the agility and scalability of a public cloud.

In the hybrid cloud, two main components are combined: 

  • Private Cloud: This is a dedicated, internal cloud infrastructure operated by a company. Sensitive data and business-critical applications are hosted here to ensure maximum control, security and compliance. 
  • Public cloud: External cloud service providers such as Amazon Web Services (AWS), Microsoft Azure or Google Cloud offer a wealth of services and resources that are available on demand. This environment allows companies to quickly expand or reduce their IT resources as needed. 

Seamless integration between the two cloud environments is achieved through powerful network connections and management tools that allow businesses to move and control workloads and data between the clouds.

What is a hybrid cloud architecture?

The hybrid cloud architecture combines private on-premise resources with public cloud services. It offers seamless integration, flexibility and scalability. Critical data can be kept secure in the private cloud while less sensitive workloads run in the public cloud. A hybrid cloud architecture allows companies to distribute their workloads and data across different cloud platforms, taking advantage of each environment.

The advantages of a hybrid cloud model

The hybrid cloud enables companies to manage their IT resources both on-premises and in the cloud and to switch seamlessly between the two environments. This offers a variety of benefits:

Flexibility and scalability: with a hybrid cloud, businesses can respond quickly to changing requirements by scaling resources up or down as needed. This enables optimal use of resources while minimizing costs.

Security and compliance: critical data and applications can be hosted in the private cloud, ensuring greater control and security. At the same time, less sensitive tasks can be outsourced to the public cloud to profit from its agility.  

Cost optimisation:companies can reduce costs by moving less business-critical workloads to the public cloud, reducing capital investment. At the same time, control over critical processes is maintained in the private cloud.

Seamless integration: Hybrid cloud allows applications and data to move seamlessly between cloud environments. This ensures optimal performance and availability. 

High availability and resilience: by combining private and public cloud, businesses can ensure that their services are always available, even if one of the environments fails.

What are the cost drivers of a hybrid cloud architecture?

The following points, a.o., must be considered when taking an economic view of a hybrid system landscape:

  • Infrastructure 
    Costs are incurred for all solutions that are operated on-premise. Cloud solutions can also incur costs for VMs or bandwidth, for example. 
  • Personnel 
    In hybrid system landscapes, different skills are needed that are not yet available in the company. This knowledge must be built up or purchased. 
  • Licences
    In a hybrid system landscape, the costs for solutions are incurred both in the on-premise area and in the cloud area. It is important to note that the billing models can vary greatly in some cases.

Best practices for a hybrid cloud approach

When setting up a hybrid system landscape, the following points can be considered as best practice:

  • Data management
    Create a strategy that considers both the optimal use of data and its security. 
  • Data compliance
    Determining and checking in which legal framework data can be used and e.g. shared.
  • Dynamic scaling 
    Determining how to react to new requirements and growing numbers of users and at which points optimisation is possible. 
  • Security 
    Establish policies that define what data is protected and in what form. 
  • Interfaces
    Determine what requirements are placed on the necessary interfaces and APIs. 
  • Monitoring 
    Implementation of guidelines, processes and tools for monitoring the system landscape. 
  • Disaster recovery
    Installation of technical solutions for the recovery of data and the maintenance of operations as well as associated emergency plans
