Development of a homogeneous IT landscape;- Started Let’sEncrypt;- Build and tune MariaDB cluster, commissioning it. Customizations of replicas and control them in Zabbix;- Created the Reserve Internet Channel System, auto-reconnect to another channel if the main channel is broken. Incident report to IT-support;- Introduced and supported systems of monitoring: Munin, Monit, and later Zabbix (many metrics and graphs). It allowed to quickly respond to changes in the company's information components, analyze the server's long-term load, and predict the load when changing part of the parameters;- Deep network upgrade with complete rework DNS, DHCP, firewall, PPTP, OpenVPN, and prepared documentation. Increased network security, ease of maintenance, and reduced response time to incidents, while reducing their number;- Transfer part of a server into the virtualized environment (Redmine, FreePBX, second DNS/DHCP/NTP, BareOS).
