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

Gitea is a lightweight, open-source, self-hosted Git service that offers repository management, code review, issue tracking, and CI/CD integration. It has become an increasingly popular alternative to GitHub and GitLab.com for teams seeking complete control over their source code without being bound by third-party terms of service or export restrictions.

GitLab Self-Managed represents the on-premises deployment of GitLab’s comprehensive DevSecOps platform, encompassing source code management, CI/CD, container registry, security scanning, and monitoring capabilities. It is widely regarded as the gold standard for organizations seeking the full GitLab feature set without reliance on SaaS services or concerns about data leaving their internal network.

This instructor-led, live training in South Korea (available online or onsite) is tailored for network engineers and infrastructure professionals who aim to deploy and manage open network infrastructure on white-box switches using SONiC and ONL.

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

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

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

This instructor-led live training in South Korea (available online or onsite) is designed for intermediate-level network engineers and infrastructure administrators seeking 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 tasks.

This instructor-led live training in South Korea (online or onsite) is designed for intermediate-level network and infrastructure professionals who wish 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 training, participants will be able to: design an open-source enterprise network architecture, configure routing, switching, and wireless services, enhance security and observability, and develop an operational plan for ongoing support.

This instructor-led live training in South Korea (online or onsite) 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 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 built specifically for self-hosted Git platforms such as Gitea and Forgejo. It delivers a lightweight, Docker-native CI/CD experience, avoiding the complexity and licensing costs associated with enterprise CI solutions.

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