Join us for a groundbreaking session on how **AI Coding Agents** are changing the game for legacy modernization. We aren't just talking about code completion; we are talking about autonomous agents that can refactor, document, and migrate entire modules with precision. ​**🚀 Session: Modernizing Legacy Projects using AI Coding Agents** ​In this deep-dive session, we will explore how to leverage the latest generation of AI agents (like Cursor, Windsurf, Devin, or custom LLM pipelines) to tackle technical debt that would normally take months to resolve. ​**What We Will Cover:** * ​**Automated Refactoring:** How to use agents to identify code smells, untangle spaghetti code, and implement modern design patterns without breaking functionality. * ​**Language & Framework Migration:** Strategies for using AI to translate old syntax (e.g., Java 8 to 21, jQuery to React) while preserving business logic. * ​**Test Generation:** How to generate comprehensive unit and integration tests for legacy code that currently has zero coverage, ensuring a safe modernization path. * ​**Documentation Recovery:** Using AI to reverse-engineer documentation from undocumented legacy systems. ​**Why Attend?** Legacy modernization doesn't have to be a painful, multi-year slog. Come see how AI agents can act as your force multiplier, turning a daunting migration into a manageable, automated workflow.

We are bringing the worlds of **Observability** and **Cloud** together. You can expect a mix of sessions covering architectural deep dives, cloud best practices, and advanced monitoring techniques. **🚀 Grafana Feature Session:** **Topic:** **Lessons from Simulating AWS T3 CPU Throttling** **Speaker:** Goh Chun Lin – Grafana & Friends Community Lead, Singapore **Synopsis:** We often use AWS burstable instances (T3/T4g) to save money, but "Unlimited Mode" can mask architectural inefficiencies by converting performance bottlenecks into silent financial debt. In this session, we go beyond standard metrics to demonstrate **Predictive Engineering**. We will show how to use **Grafana** to visualise invisible infrastructure limits and expose the true cost of performance and how to use **Discrete Event Simulation** to predict architectural breaking points as well. **🤝 Full Agenda:** In addition to the Grafana session, we will be joined by speakers invited by the AWS User Group sharing insights on cloud and infrastructure at scale. **👉 Please check the [Main Registration Page](https://www.meetup.com/aws-sg/events/312539597) for the complete lineup of speakers and topics as they are announced!** See you there!

We will start with Introduction to the Spiritual heart and then continue with relaxation and 3 short, guided meditations of around 5-10 minutes each. This will be easy and accessible for all levels, even beginners. We will continue with sharing about the heart and spirituality and how we can use Open Heart meditation in our daily life, followed by a longer Open Heart mediation. After a short break we will then have the second part of the session which is Reiki Tummo healing. This is a chance to experience the healing for yourself (to receive it) and learn about Reiki Tummo, what it is and how it can help with spiritual development and healing. The whole session will take around 2 hours with a chance to ask questions at the end. If you wish to only join for the first 1 hour for the Open heart meditation that is also possible :) This session Is free of charge :) no fees This is an in-person session held at #2-00 31 Jalan Rama Rama (DeRoyale Function Room) and by bus (Toa Payoh MRT #145/139), visitor parking is also available. Any questions please feel free to ask via Meetup or whatsapp +6588327060. We look forward to seeing you at the session :) With Love and Light Judy Chew

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.

## Learn Infrastructure-as-Code (the FUN Way) — Through Minecraft 🎮☁️ **Joint Meetup: Azure CBUS × Columbus HashiCorp User Group** What if learning Terraform and Infrastructure-as-Code didn’t feel like a whitepaper… but more like a game? Join us for a joint Azure CBUS and Columbus HashiCorp User Group meetup where **Mark Tinderholt** \(Principal Architect\, Microsoft Azure \| HashiCorp Ambassador \| “The Azure Terraformer”\) shows how **Minecraft** can be used as a surprisingly powerful way to understand real-world Infrastructure-as-Code concepts. In this session, Mark will demonstrate how Terraform and Azure can be used to provision, configure, and manage Minecraft servers—while teaching the same patterns you’d use for production cloud infrastructure. ### What we’ll cover * Infrastructure-as-Code fundamentals using **Terraform** * Provisioning real infrastructure on **Azure** * Applying **IaC best practices** (immutability, repeatability, versioning) * How playful environments like Minecraft make complex concepts *click* * Why learning through experimentation beats click-ops every time ### Who should attend * Developers, platform engineers, and cloud engineers * Terraform users (new or experienced) * Anyone curious about Infrastructure-as-Code but tired of boring examples * Minecraft fans who want to see it used in a totally unexpected way No prior Minecraft experience required—just curiosity and a willingness to learn infrastructure the fun way. Come for the blocks, stay for the Terraform. 🧱➡️📐 Want to be a speaker? submit your talk to our Call for Presenters!!! https://sessionize.com/cbus-hug-2026/
