Within a computer cluster, a group of nodes acts as a single system, which provides high availability, load balancing, and parallel data processing.
The cluster will help you handle...
Dividing traffic between several servers allows you to process more requests per hour during seasonal fluctuations, such as the Christmas rush hour.
By migrating all of the components of your services to a high-availability cluster solution, rolling application updates will run smoothly.
When a primary server fails, traffic is automatically redirected to the secondary node; as a result, the entire solution continues to run without interruption.
Solutions running in two separate locations are known as high-availability or failover clusters, and data is copied in real-time to the same backup source. If a primary site fails, the service will still run continuously.
These are clusters that run in parallel in Active / Active mode within one location (Prague or Brno). A typical example is a customer’s primary infrastructure with replication to a MasterDC data centre.
For even higher availability, choose asynchronous replication for your solution. We create the current storage copy in several time intervals and store it on hardware at a separate location – for the Prague MasterDC in Brno and vice versa.

How the cluster is negotiated and its construction
We will discuss your requirements for the security or robustness of the system (for example, based on website traffic).
We will design the cluster according to the required number of load balancers and workers in active/active or active/passive mode.
We will set up synchronous or asynchronous data replication in the cluster.
We will assemble, optimise, and get the cluster running.
We can take care of the entire solution.
Optimisation of cluster functioning
We distribute the load in the cluster between servers using load balancing. We also offer this as a separate service for customers whose IT already runs on several servers. We also provide DNS load balancing or DNS redirection.
