Cluster for High-Voltage Systems

A great choice for those who value productivity and uninterrupted business operations

High-load projects include real-time-API modules, payment systems (Portmone, Visa), BigData systems, Artificial Intelligence, ERP, Business Analytics, etc.

When you need a cloud that can withstand high workloads:

  • An avalanche-like increase in user load - the peak number of users accessing the system at the same time and the number of requests from each (Black Friday);
  • when "bottleneck" appears, which gets clogged with increasing number of requests due to inability to pass them through the subsystem and process the request (slow disks or incorrectly configured cache do this very quickly);
  • when there is a load on only one subsystem;
  • when several (two or more) systems are loaded at once and the overloading of the other does not depend on the first.

UCLOUD cluster for high-load systems is based on AMD processors and NVMe disks. This combination of resources ensures maximum performance and efficiency.


  • The first server processor based on x86 architecture and the corresponding PCIe 4.0 interface,
  • delivers the best performance in synergy with NVMe storage.

PCIe 4.0 interface:

  • 2x more I/O performance than PCIe 3.0,
  • 128 I/O lines and can aggregate multiple clusters,
  • Keep performance-intensive clusters running smoothly.

The advantages of using a cluster for high-load systems


If performance problems occur, you can instantly increase the amount of available resources (CPU, memory, disk), optimize/eliminate bottlenecks and then quickly roll back the amount of resources to an acceptable level.

When users, base loading or calculations and computations increase, high-performance clusters provide better power.

Disks, networks and hot-swap hardware are always a bottleneck in a perfectly stacked highlayer of systems. Ucloud uses NVMe-based storage and hot-swaps servers if some of them fail.

At the design stage, it is necessary to architecturally lay down the basic patterns inherent in a loaded architecture. For example, data partitioning (partitioning of similar data between database nodes), etc. Ucloud specialists have great experience in designing IT systems architecture and will help you to identify and take into account the bottlenecks at an early stage.

Using a set of servers for high-load systems allows you to not lose time and money due to failure or stoppage.

UCloud company was the first among Ukrainian operators to build a cloud data center based on AMD+NVMe. Microsoft, Google, AWS, PlayStation, Xbox and others are among the world examples of using the complex.

A cluster of highly loaded systems on AMD processors using NVMe storage system from UCloud will be useful for smooth and trouble-free operation:


  • heavy workflow, accounting, etc. application servers in the cloud;
  • "heavy" application servers;
  • voluminous databases;
  • large terminal farms;
  • sites with an audience of more than 10,000 visitors, etc.
  • test implementation of ERP
  • use of a hybrid approach to predictable seasonal workloads.

UCloud is a silver partner of Microsoft, and also cooperates with Ukrainian (VOLZ) and European (Fiberax) companies to organize data transmission channels.
