NixOS: Declarative Linux for Reproducible Sovereign Infrastructure Training Course

Gitea is a lightweight, open-source, self-hosted Git service that provides repository management, code review, issue tracking, and CI/CD integration. It serves as a popular alternative to GitHub and GitLab.com for teams that require full autonomy over their source code, avoiding third-party terms of service and export restrictions.

GitLab Self-Managed is the on-premises deployment of GitLab's complete DevSecOps platform, including source code management, CI/CD, container registry, security scanning, and monitoring. It is the gold standard for organizations that want the full GitLab feature set without SaaS dependency or data leaving their network.

This instructor-led, live training in Latvia (online or onsite) is aimed at intermediate to advanced DevOps engineers and system administrators who wish to deploy and manage self-hosted Kubernetes clusters without cloud dependencies.

By the end of this training, participants will be able to: deploy production-ready Kubernetes clusters using kubeadm on bare-metal or virtual machines; configure high-availability control planes and etcd clusters; implement container networking and storage for self-managed environments; set up monitoring and observability using self-hosted solutions.

This live, instructor-led training (online or on-site) is designed for cloud professionals aiming to create and implement multi-cloud architectures that prevent vendor lock-in while ensuring data sovereignty.

By the end of the program, participants will be capable of identifying lock-in risks, designing portable architectures, implementing sovereignty controls, and utilizing cloud-agnostic tools.

This instructor-led live training in Latvia (online or onsite) is designed for network engineers and infrastructure professionals aiming to use SONiC and ONL to deploy and manage open network infrastructure on white-box switches.

By the end of the course, participants will be able to understand SONiC and ONL architectures, deploy open-source NOS on white-box hardware, configure networking features, and implement monitoring and automation.

This live, instructor-led training, offered online or on-site, is tailored for system administrators and infrastructure engineers looking to design, deploy, and manage private OpenStack cloud infrastructure within enterprise environments.

By the end of the program, participants will be equipped to understand OpenStack architecture, deploy private cloud infrastructure, manage compute and storage resources, implement security via Keystone, and apply best practices for enterprise deployments.

This live, instructor-led training in Latvia (delivered online or onsite) is tailored for intermediate-level network engineers and infrastructure administrators who aim to implement software-defined networks using open source tools and technologies.

By the conclusion of this training, participants will be capable of designing SDN architectures, implementing Open vSwitch, configuring FRRouting, deploying SDN controllers, and automating network management.

This live, instructor-led training in Latvia, available online or onsite, targets intermediate network and infrastructure professionals. It equips them to design, deploy, and operate self-managed enterprise networks using open-source tools for routing, switching, Wi-Fi, and management.

By the end of the training, participants will be able to: design open-source enterprise network architectures, configure routing, switching, and wireless services, enhance security and observability, and establish an operational plan for continuous support.

Uptime Kuma is a straightforward, self-hosted monitoring tool that tracks the availability of websites, services, and infrastructure. It serves as a viable replacement for Pingdom, Datadog Synthetics, and UptimeRobot, empowering teams to retain direct control over their monitoring data. This instructor-led, live training (delivered online or on-site) is designed for beginner-to-intermediate SREs and DevOps engineers looking to replace cloud-based uptime monitoring with a self-hosted, sovereign status tracking platform.

This live, instructor-led training in Latvia (available online or on-site) targets security engineers and system administrators seeking to deploy and manage enterprise-grade self-hosted VPN solutions using WireGuard and OpenVPN.

By the end of the session, participants will be proficient in deploying WireGuard and OpenVPN, designing scalable architectures, integrating identity systems, and monitoring and securing the VPN infrastructure.

OpenVPN and WireGuard stand as the leading open-source VPN protocols. By operating your own VPN server, you eliminate the risk of third-party providers logging traffic metadata, injecting ads, or yielding to foreign data requests. This training explores both protocols to address various threat models and performance needs.

Wazuh is an open-source security platform that provides unified XDR and SIEM capabilities for threat detection, integrity monitoring, incident response, and compliance. It aggregates endpoint telemetry into a self-managed analysis engine, positioning itself as a strong alternative to Splunk Enterprise Security, Microsoft Sentinel, and other cloud-native SIEMs.

Woodpecker CI is a straightforward and robust continuous integration engine tailored for self-hosted Git platforms such as Gitea and Forgejo. It delivers a streamlined, Docker-native CI/CD solution, eliminating the complexity and licensing costs associated with enterprise CI systems.

This instructor-led, live training in Latvia (online or onsite) is designed for intermediate to advanced security professionals looking to implement Zero Trust Architecture using open-source tools and sovereign infrastructure.

By the end of this training, participants will be equipped to design Zero Trust architectures, deploy identity-aware proxies, implement dynamic authentication, secure microservices with service mesh, and monitor zero trust policies.
