IT Infrastructure, DevOps, and Security

Cluster, Failover, and Backup Systems

Infrastructure designed for high availability and uninterrupted service:

• Active/Passive and Active/Active Architectures: Solutions that ensure service continuity with instant failover in case of primary server failure; active/active clusters distributing load horizontally across multiple nodes.

• Load Balancing: Balanced traffic distribution across servers using open-source or enterprise-grade solutions like Nginx, HAProxy, Apache, or Envoy; flexible configurations with health checks, SSL termination, and Layer-7 routing rules.

• Snapshot & Offsite Backup: Periodic snapshots scheduled based on data volume; encrypted backups of critical server images and databases to remote locations; disaster recovery (DR) procedures and automation scripts included.

Firewall, Network, and Monitoring Systems

Comprehensive solutions combining network security and performance monitoring:

• Firewall & IDS/IPS: Layer 4/7 firewall rules, intrusion detection/prevention systems (e.g., Snort, Suricata) that instantly isolate suspicious traffic.

• VLAN & VPN: Logical isolation between departments or projects via virtual LANs; secure remote access networks with OpenVPN, IPsec, or WireGuard.

• Network Monitoring & Logging: Real-time statistics on traffic, latency, packet loss, and connections via PRTG, Zabbix, or Grafana dashboards; SMS/email alerts when critical thresholds are exceeded.

DevOps & Cloud Infrastructure

Modern application platforms uniting development and operations through continuous integration:

• CI/CD Pipelines: Configurations using GitLab CI, Jenkins, or GitHub Actions to test, build, and deploy code on every commit; includes rollback and canary deployment strategies.

• Containers & Orchestration: Portable app packaging with Docker; automated scaling, self-healing, and service discovery via Kubernetes clusters.

• Cloud Migration & Optimization: Infrastructure deployments on AWS, Azure, or GCP; cost analysis, resource optimization, and integration with cloud-native services.

Virtualization and Server System Installations

High-performance server infrastructure across physical and virtual layers:

• VMware, Proxmox & Hyper-V: VM pools tailored to your virtualization platform; live migration and snapshot management.

• High Availability: Failover clusters, shared storage integration (SAN/NAS), and replication strategies minimizing service disruption.

• Server Setup & Configuration: Secure and optimized setups of web servers (Nginx, Apache, IIS) on Linux distributions (Ubuntu, CentOS, Debian) and Windows Server.

• Email and File Servers: Email infrastructure using Exchange Server or open-source alternatives; FTP/SFTP and file-sharing solutions.

• DNS, DHCP & Domain Controllers: Corporate network management with Microsoft Active Directory or open-source DNS/DHCP services; user and group policy management.

• CDN & Content Delivery: Fast delivery of static and dynamic content through CDN integrations providing global caching endpoints.

DLSS, DPS, and Antivirus Solutions

Security layers balancing threat prevention and system performance in enterprise environments:

• DPS (Dynamic Protection System): Real-time cyberattack analysis, traffic inspection, and automated access control updates.

• DLSS (Dynamic Load Shedding Service): Smart filtering of unnecessary traffic during high-load scenarios to preserve the performance of critical applications.

• Antivirus & Endpoint Security: Centrally managed virus scanning, malware detection, and regular signature updates; endpoint isolation and quarantine policies.

Zero Trust and Identity Management

Security beyond network perimeters based on continuous verification:

• Zero Trust Architecture: "Never trust, always verify" principle with continuous identity verification, authorization checks, and least privilege access.

• Multi-Factor Authentication (MFA): Additional layer of login security using SMS/OTP, mobile app verification, or security keys.

• LDAP, SSO, SAML & OAuth2: Seamless single sign-on (SSO) experiences via internal directory services (LDAP/AD) and cloud applications (SAML/OAuth2).

• ADFS & Azure AD Integration: Secure identity federation between cloud and on-premises resources using Active Directory Federation Services or Azure AD.

Log Management and SIEM Systems

End-to-end monitoring from threat detection to incident response:

• Centralized Log Management: Aggregation and indexing of all server and application logs using ELK Stack (Elasticsearch, Logstash, Kibana), Graylog, or Fluentd.

• SIEM Solutions: Real-time correlation, alerting, and reporting with platforms such as Splunk, Wazuh, IBM QRadar, or OSSIM; includes threat hunting capabilities.

• SOAR (Security Orchestration, Automation, and Response): Automated response playbooks speeding up initial triage, isolation, and remediation processes.

High Availability and Performance in Databases

Ensuring your enterprise data layer is always available and fast:

• Galera & Patroni Clusters: High availability and data consistency with MySQL/MariaDB Galera Cluster or PostgreSQL Patroni architectures.

• Redis & MongoDB High Availability: Scalable in-memory cache and document DB with Redis Sentinel/Cluster and MongoDB Replica Sets or Sharding.

• Replication & Backup Strategies: Asynchronous/synchronous replication topologies, logical/machine dumps, and continuous backup via specialized tools.

• Query Tuning & Performance Monitoring: Query analysis tools and automatic performance alerts; index optimization, query profiling, and parameter tuning.

Each layer and component can be fully customized to match your organization’s security, performance, and scalability goals. We’re here to support you with detailed infrastructure analysis, project planning, and 24/7 expert support.
