Join the **Manchester Java Community** for an evening of deep-dive technical insights with **Dmitry Chuyko** ([https://www.linkedin.com/in/dchuyko](https://www.linkedin.com/in/dchuyko)), Senior Platform Architect at BellSoft. Dmitry will be presenting two specialized sessions essential for modern Java and DevOps engineers. Session 1: Why you need performance tests for proper K8s scaling Kubernetes is powerful for rapid scaling, but "default" container configurations often lead to resource misuse and unexpected cloud costs. Learn how to align developer efforts with business KPIs through effective performance testing. We will explore how containers impact service behavior, how to leverage microcontainers and native images, and how to measure utilization to build safer, more cost-efficient deployments. Session 2: From Kitchen to Table: A Safe Software Journey with SBOMs Think of your containerized Java application as a complex dish served to production. Just as you wouldn't trust a kitchen with hidden ingredients, you shouldn't deploy software without knowing exactly what's inside. This practical talk cuts through the complexity of SBOMs (Software Bill of Materials). We will discuss: Enforcing security policies at CI/CD stations (GitLab/GHA). Verifying manifests for hardened containers. Passing Kubernetes health inspections (OPA/Ratify). Navigating competing formats like SPDX and CycloneDX to turn SBOMs into actionable security artifacts. Whether you are a developer looking to optimize costs or a DevOps engineer focused on secure supply chains, these sessions offer actionable, real-world strategies. Agenda: 5:00 PM: Networking 6:00 PM: Talks and Q&A to follow 🙌 **Sponsored by Morson Edge** Special thanks to our event sponsor **Morson Edge** for providing the food and refreshments for the evening and supporting the MJC community!
