centron Managed Cluster: Complete service for your digital success
The word “cluster” in information technology refers to a group of servers that look like a single server to the outside world. Clusters can be found in almost every sector and every industry – whether database clusters, application clusters or email clusters. Today, clusters are indispensable, especially for cutting-edge technologies such as virtualization platforms, cloud computing or big data. In principle, clusters can be divided into the following types:
✅ High availability cluster / high availability cluster (HA)
✅ Hochleistungscluster / High-Performance-Computing-Cluster (HPC)
✅ Loadbalanced Cluster
We have compiled a series of sample configurations for you below. In practice, however, it is always advisable to adapt a cluster to the requirements under real conditions. Our IT consultants will be happy to advise you and analyze your requirements. We can draw on our wealth of experience from countless customer projects to find the perfect system for your application.
Maximum high availability for business-critical applications
centron’s managed clusters offer an impressive high availability of 99.9% or higher. Our emergency cluster solutions ensure that your cloud applications and websites are always available, even under high request loads. With load balancing, incoming traffic is optimally distributed so that your users can always access content and services with short access times. In addition, the redundancy of all system components ensures that downtimes are reduced to a minimum.
Flexibility and scalability
Our managed clusters are not only powerful, but also extremely flexible. You can expand and adapt your IT infrastructure as required. Whether you need additional resources for growing projects or want to optimize your cluster solution – centron offers you the flexibility you need. With two-server clusters, you already achieve a significant increase in performance and can switch to a load-balanced cluster or failover cluster if required.
Safety and efficient management
Security is centron’s top priority. Our ISO 27001-certified data centers offer maximum data security for your cluster solutions. In addition, we take care of the complete cluster management, including maintenance, updates and security management, so that you can concentrate fully on your core business.
Functionality and sample configuration of a managed load-balanced cluster
What are the advantages of a two-server solution?
With a two-server solution as shown in the diagram, the operator benefits from better performance compared to a solution with just one server. This is achieved through the division of tasks within the managed cluster. While the web server processes all requests from the network, the database server simultaneously provides the corresponding data. A particularly attractive feature of this system architecture is that additional resources can be added to the landscape at any time.
Performance
Two-server clusters offer you the best performance and speed even with high traffic and large projects.
Division of tasks
The web server processes requests from the network, while the database server provides it with the necessary data.
Flexibility
Not sure where the journey will take you? With a cluster, you have all the freedom you need to simply increase your resources as required.

What are the advantages of a load-balanced cluster solution?
With a load-balanced cluster, you can ensure that the system load in your IT landscape is always optimally distributed. This means that content and services are always available to your users with high performance and extremely short access times can be achieved, even with a very high volume of requests. Load balancing also increases security against outages, as the traffic of a slow server is automatically forwarded to another server in the cluster.
Individual clusters
Depending on the deployment scenario, you have a wide variety of requirements for your IT infrastructure. We design your cluster so that it works optimally.
High availability
We design your managed cluster so that all components are redundant. This ensures that your data and services always remain highly available.
Independent
Our load balancing solutions are scalable as required. You decide the level of data security and availability yourself.
Functionality and sample configuration of a managed failover cluster
What are the advantages of a failover cluster solution?
A failover cluster is the ultimate in IT when it comes to reliability and system availability. Such IT landscapes ensure high availability for particularly important applications and services. If a node within the cluster fails or has a problem, another system takes over the workloads during operation. This means that there is no downtime. Maintenance work can also be carried out without downtime.
Reliability
If a server fails in a worst-case scenario, its work is reliably taken over by another node in the managed cluster without any downtime.
Active-Active Cluster
With this type, your services are operated in parallel on all existing nodes. If a fault occurs, another node simply takes over.
Active-passive cluster
With this type, the slave servers are subordinate to a master. In the event of a fault, the slave takes over, but otherwise remains inactive.
Managed Cluster FAQ
Everything you need to know about centrons Managed Cluster, High Availability Cluster, and Cluster Management
What is a managed cluster and why is it important?
A managed cluster is a group of servers that work together to ensure maximum availability and performance. This solution is ideal for companies that run business-critical applications and want to avoid downtime.
What are the advantages of a failover cluster?
A failover cluster ensures that another server automatically takes over in the event of a server failure, thereby avoiding downtime. This solution offers maximum reliability and is particularly important for applications that need to be available around the clock.
How do I scale my Managed Cluster at centron?
centron offers flexible options for scaling your cluster solution. You can add additional servers and resources at any time to meet the requirements of growing projects.
