Installing and managing Linux servers

Information technology enables companies to function effectively in today's modern age.Businesses use a lot of software to work and have a lot of data.

However, every software and data must run on a computer, ideally a server, and the data must be stored on the server. Sometimes these are virtual servers called VPS , but each virtual server must run on a physical server.

All this software and data must be taken care of on an ongoing basis to keep everything running smoothly and without problems. And so the servers need ongoing management and gradual upgrades. Therefore, a good company cannot do without an IT specialist today.

Linux is the standard in servers. It is the most used operating system on servers due to its qualities, which are: performance, scalability, stability and efficient management.

LAMP or Linux + Apache + Mysql + PHP is the most common combination of server software that serves as a web server for running web applications.

Our story

about img
We supply tailor-made solutions

We prepare custom servers.Installing Linux changes the Debian distribution to virtual (VPS) or physical / dedicated servers.Where the default installation is not sufficient, we optimize the configuration of the system to measure or add additional software to the system.

In case of problems during the application and interactions with the Internet, we analyze the problem and, based on that, suggest possible solutions.

We provide application migration and optimization for the performance of web and database applications.

Custom application development (desktop, web, embedded).

We perform project analysis based on consultations of customer needs.

We provide automatic backup.

We analyze the state of the system and implement mechanisms to increase server security.

    Linux on a physical server

    The VPS typically comes with a preinstalled operating system. However, if you have a physical server (baremetal), whether leased or owned, you must first install the operating system.
    It is best to install Linux on a physical server and then install the necessary server applications.
    Professional installation will ensure the correct operating system settings for the hardware.

    Web speed is a fundamental thing that affects the use of the application.

    Verify web page speed and speed up slow pages!
    details

    Web stress test

    Web speed is a fundamental thing that affects the use of the application. If the web server does not manage to handle the requests of users, this is a problem. An even bigger problem occurs in the case of concurrent user accesses, when the web application may stop working or the web server may reject new user requests. Verification of the good functionality of the wevobé application and the web server can be done by a stress test.
