Frequently Asked Questions
What advantages does virtualization provide for my business?
Virtualization reduces energy and maintenance costs by decreasing the number of physical servers. You also gain fast backups, easy scaling, and high availability.
Which operating systems do you support?
We provide support for all major server operating systems, including Linux distributions (Ubuntu, CentOS, Debian, Rocky Linux) and Windows Server (2016, 2019, 2022).
Should I choose Docker or virtual machines?
Docker is ideal for microservice architectures and rapid deployment. Virtual machines are better suited for full isolation and different operating systems. Both can be used together based on your needs.
What should a server backup strategy look like?
The 3-2-1 rule applies: 3 copies, 2 different media, 1 remote location. Daily incremental and weekly full backups are performed for critical systems, verified through regular restore tests.
How long does Active Directory setup take?
A basic AD setup is completed in 1-2 days. When including user migration, GPO configuration, and application integrations, a 1-2 week timeframe should be planned.
What kinds of issues can server monitoring detect in advance?
Disk capacity warnings, CPU/RAM bottlenecks, service outages, network anomalies, and security breach attempts are detected and addressed before they escalate.
Every problem is different. No cookie-cutter solutions — I listen first.
