Uptime Kuma: Self-Hosted Monitoring Replacing Datadog and Pingdom Training Course

Gitea is a lightweight, open-source solution for self-hosted Git services, offering repository management, code review capabilities, issue tracking, and CI/CD integration. It has become a preferred choice for teams seeking full control over their source code without being bound by third-party terms of service or export restrictions, serving as a viable alternative to GitHub and GitLab.com.

GitLab Self-Managed refers to the on-premises deployment of GitLab's all-encompassing DevSecOps platform, which encompasses source code management, CI/CD, container registry, security scanning, and monitoring. It serves as the industry benchmark for organizations seeking the complete GitLab feature set without reliance on SaaS solutions or allowing data to exit their internal networks.

This instructor-led live training in Greece (online or onsite) is aimed at network engineers and infrastructure professionals who wish to use SONiC and ONL to deploy and manage open network infrastructure on white-box switches.

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

This instructor-led live training (online or onsite) is designed for system administrators and infrastructure engineers who wish to design, deploy, and manage private OpenStack cloud infrastructure for enterprise environments.

By the end of this course, participants will understand OpenStack architecture, deploy private cloud infrastructure, manage compute and storage resources, implement security with Keystone, and apply enterprise best practices.

This instructor-led, live training in Greece (online or onsite) is aimed at intermediate-level network engineers and infrastructure administrators who wish to implement software-defined networks using open source tools and technologies.

By the end of this training, participants will be able to design SDN architectures, implement Open vSwitch, configure FRRouting, deploy SDN controllers, and automate network management.

This instructor-led live training in Greece (online or onsite) is designed for intermediate-level network and infrastructure professionals who aim to utilize open-source routing, switching, Wi-Fi, and management tools to design, deploy, and operate a self-managed enterprise network.

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

This instructor-led, live training in Greece (online or onsite) is aimed at security engineers and system administrators who wish to deploy and manage enterprise-grade self-hosted VPN solutions using WireGuard and OpenVPN.

By the end of this training, participants will be able to deploy WireGuard and OpenVPN, design scalable architectures, integrate with identity systems, and monitor/secure VPN infrastructure.

OpenVPN and WireGuard are the two dominant open-source VPN protocols. Running your own VPN server ensures that no third-party provider can log traffic metadata, inject advertisements, or comply with foreign data requests. This training covers both protocols for different threat models and performance requirements.

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

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

This instructor-led, live training in Greece (online or onsite) targets security professionals at intermediate to advanced levels who wish to implement Zero Trust Architecture using open-source tools and sovereign infrastructure.
