System requirements

This guide outlines the hardware requirements of the Ozeki software. You will first find the basic definitions and the recommended hardware configurations. You will find information about the supported operating systems, and the recommended hardware setup for you system.

Terms and definitions

Connection: A connection is typically defined as a link to the outside world. For example, a link to a mobile network or a link to a database server would be a connection. Connections are able to receive and send messages. Hardware requirements depend on the number of connections you wish to setup.

Message throughput: The number of messages that travel through the system. It is measured in Messages per Second (MPS) or for lower capacity systems in terms of Messages per Minute (MPM). The message engine in Ozeki was designed to handle a maximum of 1000 messages per second on a single computer. Higher throughput can be achieved using multiple computers.

CPU: Bursts of high message throughput require higher single core performance. A high number of connections require higher number of thread processing capabilities. When choosing a CPU hierarchy for your system consider how you wish to use Ozeki. For best performance we recommend top of the line Multi core Intel CPU's. AMD CPUs are supported based on their equivalence to the suggested Intel CPUs.

Memory: For increased performance, Ozeki caches message queues in memory. Make sure to put as much RAM into your system as possible, since this will greatly improve your system's performance.

Network: Ozeki can operate on lower network speeds, but a 1Gb LAN network connectivity is recommended. Depending on the number of simultaneous connections and the message throughput the network bandwidth can be a limiting factor.

Supported operating systems

Ozeki 10 supports the following operating systems. All operating systems must be installed in their x64 version. 32-bit versions are not compatible with Ozeki. Full Windows and Linux updates are also mandatory to be applied to ensure compatibility with Ozeki.

Windows 11
Windows 10
Windows 7
Windows Server 2022
Windows Server 2019
Windows Server 2016
Ubuntu LTS 20.04
Raspbian Stretch
