Server Clusters


Use tailor-made and powerful server cluster solution to increase data availability, security level and computing requirements.

For complex, high-traffic sites or applications where downtime is not an option, distribute the workload across multiple servers in a cluster to maximize throughput, minimize response time and avoid overload. If one cluster node goes down, then the remaining cluster nodes can continue servicing requests so that users see little or no loss of availability.

Choose different clusters depending on your business needs:

  • High-availability cluster (HA)

  • Load balancing cluster (NLB)

  • High performance computing cluster (HPC)

Payment Card Industry's Data Security Standards (PCI DSS)

If your company accepts, stores, processes or transmits credit card data online or offline, you are most likely in need of PCI DSS compliance. DEAC is PCI compliant and has implemented a complex network architecture to meet the robust PCI DSS policy. DEAC cluster solutions ensure full compliance to our customers.

Big Data Analysis Platform

Choose Hadoop, Apache Spark, Apache Storm or Disco big data frameworks that enable to process large amount of data efficiently. These big data analysis platforms allow to analyze massive data sets in parallel by using server clustering. Distributed computing platforms split big data across multiple nodes within a cluster of commodity servers, which means you don't need to buy and maintain expensive custom hardware. DEAC provides fully configured clusters to run any of these open-source projects and other applications in the chosen platform.

How a server cluster works?

A server cluster consists of several physical servers, called nodes, that connects with each other to ensure highly available services to customers. Cluster computing consists of resource groups that are made of applications and services, as well as resource group configuration to include all elements for the applications, associated network name and IP address. Each node can have multiple resource groups and resources can have specific dependencies to indicate which one needs to come online or offline during failover. This allows to run collection of resources as a separate server on the network. You can use server clusters for file servers, database servers and messaging servers.

DEAC’s high availability cluster runs on each node and controls server cluster’s operations. There are multiple software components to ensure monitoring, transfer resources from one node to another and maintain consistency of cluster computing.

Usual components of server clusters

Each server cluster differs with its components and internal control system. Usual server cluster components are database manager, node manager and failover manager, which work closely together to ensure great performance.

  • Database manager maintains a local copy of the server cluster configuration database, which contains information about all items in a cluster and it replicates all changes to all nodes in the cluster.

  • Node manager provides a local list of nodes, networks and network interfaces in the cluster and ensures that all nodes in the cluster have the same list of functional nodes. Node manager also monitors nodes to detect node failure.

  • Failover manager manages resource dependencies, launches resources and initiates failover of resource groups; as well as determines which resource group should be on each node and if necessary, reassign nodes ownership of the resource group to another.



What is the difference between the server and the cluster?

Server clusters are used when servers can’t be effective enough and your business needs more and more powerful servers to ensure operations. Server clusters are used for large scale projects or business IT processes with fast site upload and high availability as the main factors. Instead of one server, there are two or more servers with specified configuration in the server cluster. Load balancers are used to organize which server will receive each response.

What's the difference between a 64-core cluster and a 64-core server?

Server cluster consists of many different physical hosts. All cores are in these servers' processors, and they are connected together with a high speed interconnect and management software. In a 64-core server, all cores are in processors that are in a single physical server.

Can I cluster my existing server?

Of course, you can cluster one or multiple existing servers. Clustering of multiple servers will provide load balancing.

Is it possible to reach my clustered servers directly?

Yes. You will be provided with a virtual IP that represents the cluster and each server will have its own real IP that can be used to access the server directly.

Can I add or remove servers from my cluster without downtime?

Yes, load balancing allows you to add or remove servers from the cluster with zero downtime. It also allows to upgrade the OS or any other software on one clustered server at a real time, without interruptions.
