IT services
We design and implement servers, data storage, and other systems for various purposes based on Linux or Windows, required for your operations. We assess the current state of the company’s IT infrastructure and propose effective solutions that help increase performance, optimize system operations, and ensure data security.
When providing IT services, we first focus on the correct design of the systems. In this way, we ensure that:
- systems do not interfere with each other’s work;
- data streams do not blindly block the network;
- one system would not dispose of the resources required by other systems;
- there would be no slowdown or jerking of systems.
Systems we work with:
Linux systems, computer networks
• Linux servers and routers (RedHat, CentOS, Debian, Ubuntu).
• Cloud computing (Opennebula, Cloudstack, Openstack, KVM).
• High Availability systems (Keepalive, VRRP, Pacemaker, Corosync).
• LAMP systems (Linux, Apache, MySQL, PHP).
• Databases (MySQL, PostgreSQL).
• Email servers (Exim, Postfix, Spamassassin).
• VPN routers (IPSec, OpenVPN, Racoon, OpenSWAN).
• Data storage systems (Ceph, ZFS, iSCSI, NFS).
• Monitoring servers (Zabbix, Cacti, Smokeping).
• Backup servers (Ahsay, rsync).
Windows systems
• Microsoft Windows Server.
• Microsoft Exchange server.
• Microsoft SQL Server.
• Microsoft Internet Information Services (IIS).
• Microsoft Active Directory.
Linux RAID storages that are applied to small and medium-sized enterprise file servers, small clouds or video surveillance data storages.
• NFS, iSCSI, LVM connectors.
• RAID0, RAID1, RAID10, RAID5, RAID6.
• Hotspare disks.
• Automated disk checks.
• Alerting in case of hard drive failure.
• Snapshots.
• Data backups to remote servers (full and incremental).
• Independence from hardware vendors: In the event of a failure of the disk controller, it can be replaced by any manufacturer's controller.
ZFS data storages that can be applied to high-speed file servers and mid-range Cloud or video surveillance data storages.
• NFS, iSCSI, LVM connectors.
•RAIDZx. x – ZFS “RAID” level.
• Checksums on read and write operations.
• Copy-on-write file system.
• SSD write cache.
• Automated disk verifications.
• Alerts in case of disk failure.
• Snapshots.
• Remote backups (Full and incremental).
• Independence from hardware vendors: In the event of a failure of the disk controller, it can be replaced by any manufacturer's controller.
Distributed Ceph data and object storages that can be applied to high-speed and high-capacity file servers, Web and other applications, large cloud data, objects, video surveillance systems data storages.
• Scale-out system - speed and capacity increase by connecting additional servers.
• Practically unlimited possibilities to increase speed and data capacity.
• Snapshots.
• Data tiering.
• Copy-on-write cloning.
