LVServer Clusters
Server cluster computing is a powerful solution for companies with high security standards, nonstop data availability and computing requirements. This solution is suitable for the maintenance of the corporate databases, social sites and news portals, e-commerce websites, online games, high traffic gambling portals, insurance and credit institutions, software developers and testers.
Nonstop availability
Guaranteed uptime delivery not lower than 100% for uninterruptible service in case of equipment failure
High scalability
Large number of equipment available, predictable and easy to increase and decrease computing capacity according to business needs and growth
Reliable technical equipment
High quality equipment from leading manufacturers in secure data centers
Server cluster is a solution of merged several physical servers and network infrastructure, that handles various processes in common resource. Customer receives servers and data storage system with the required amount of processors, RAM (Random Access Memory) and HDD (Hard Disk Drive) capacity. In addition, customer is provided with the necessary server cluster’s network infrastructure. Every solution is based on the customer’s technical requirements and service implementation time usually takes up to several business days. It is important that server cluster can be accessed from anywhere, as long as you have access to the Internet. All data and programs are hosted in server clusters that are located in DEAC secure data centers in London, Frankfurt, Stockholm, Amsterdam, Riga, Kiev or Moscow.
We offer to create different clusters depending on the customer’s requirements:
High-availability cluster (HA) Load balancing cluster (NLB) High performance computing cluster (HPC)
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. Server clusters can be specifically configured to be fault-tolerant. 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. This not only ensures high performance, but also ensures redundancy. Load-balancing also allows to upgrade the OS or any other software on clustered servers at a real time, without interruptions, as well as upgrade from two to dozens of servers whenever your business demands it.
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.

Usability of server clusters
How a server cluster
works?
Usual components of
server clusters
Server clusters are most often used in business where high data availability is the main factor.
- E-commerce
- Online gambling and online casinos
- Companies that maintenance databases
- Medical industry
- Stock exchange industry
- Finance industry
- Insurance institutions
A server cluster consists of several physical servers, called nodes that connects with each other to ensure services highly available 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.
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.
Payment Card Industry's Data Security Standards (PCI DSS) is an information security standard for businesses that handle cardholder information. 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 complies with the PCI DSS policy and ensures full compliance to our customers.

FAQ
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 is used to organize which server will receive each response.
Server cluster consists of many different physical hosts. All the cores are in these servers processors and they are connected together with a high speed interconnect with management software. In a 64 core server, all cores are in processors that are in a single physical server.
Of course, you can cluster one or multiple existing servers. Clustering of multiple servers will provide load balancing.
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.
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.
