Microsoft Events’ Ignite session with Karl Abbott and Lachlan Evenson explores deploying, securing, and optimizing Linux workloads on Azure using native tools and partner integrations.

Optimizing Linux Deployments: Performance and Security on Azure

Overview

This Microsoft Ignite 2025 breakout session, led by Karl Abbott and Lachlan Evenson, focuses on advanced techniques for managing Linux environments on Azure—ranging from Ubuntu to Rocky Linux. It highlights Microsoft’s open source contributions and the technical strategies for creating robust, performant, and secure cloud-native Linux architectures.

Key Topics

  • Azure-Native Tools for Linux: Utilizing Azure Monitor and Defender for Linux to stay compliant, monitor, and secure workloads.
  • Streamlining Image Creation: How to deploy and customize Red Hat-based images and integrate existing licenses.
  • Workload Hardening & Compliance: Implementing secure baselines for VM images and maintaining compliance.
  • Performance Monitoring & Tuning:
    • Using eBPF and Inspector Gadget for deep packet and system inspection.
    • Network performance tuning (TCP optimizations, configuration changes), with practical demos of applying tuning files and measuring throughput improvements (up to 710 Mbps).
  • Operational Demos:
    • Deploying a Linux VM via Azure portal and SSH verification.
