From Logs to Insights: Real-time Conversational Troubleshooting for Kubernetes with GenAI
In today’s distributed microservices landscape, Kubernetes environments generate vast volumes of logs, making troubleshooting complex and time-consuming. Operators often sift through massive data to identify issues, leading to prolonged downtime—a challenge that intensifies with multiple clusters. Discover how GenAI optimizes troubleshooting by transforming traditional logs into conversational insights. This session covers building an AI-driven observability solution with Large Language Models (LLMs). We start by configuring Fluent Bit collectors to gather systemd logs, Kubernetes events, and application logs, which are then streamed to a scalable object storage. By constructing a vector database, we enable users to query and interact with logs in natural language. We will provide a step-by-step guide that equips attendees with actionable knowledge to implement GenAI observability in their Kubernetes clusters.
Streamline Kubernetes Deployments with Helm, GitOps, and Terraform for SaaS
Engineers often face challenges in reusing code, slowing delivery. GitOps, Terraform, and Helm can offer standardized and reusable assets, streamlining application deployments alongside infrastructure components enabling governance and reducing toil.
Kubernetes Autoscaling: Beyond One-Size-Fits-All
There’s no one-size-fits-all approach to Kubernetes autoscaling. Fitting the right pieces together requires a deep understanding of the various autoscaling dimensions and the open-source projects that can plug in to meet specific use cases.
This session will explore the three key dimensions: cluster, horizontal, and vertical. We’ll start with the tools built into Kubernetes before moving onto the more advanced open-source projects—Karpenter and KEDA, which enhance flexibility and efficiency for each.
Attendees will learn:
- Strategies for cluster, horizontal and vertical autoscaling, their challenges, and solutions that improve on or replace them
- How to assess workload requirements to choose the right mix of autoscaling tailored to specific app needs
- Best practices to optimize deployments for peak performance and cost-efficiency for dynamic workloads

From Chaos to Control: Structuring Repositories for Scalable GitOps on Kubernetes
As Kubernetes adoption grows, maintaining consistency across clusters becomes increasingly challenging, especially during upgrades. Kubernetes upgrades can be complex due to several factors, such as managing dependencies on specific add-on versions and handling deprecated and removed API versions.
This session addresses repository standardization within a GitOps framework. Join us to explore best practices for organizing repositories to improve upgrade management and consistency across Kubernetes environments. We’ll examine different approaches, from MonoRepo strategies (for all components or just add-ons) to a repo-per-cluster setup, comparing the pros and cons of each. Using Fluxv2, Kustomize, OpenTofu, and Helm, we’ll provide real-world examples that illustrate how centralized repository organization enhances Kubernetes GitOps, helping attendees streamline application and add-on deployments, manage variables across clusters, and maintain consistent versions.
Kubernetes DevOps tooling meets SaaS: Tenant provisioning, updates, and deprovisioning.
Software-as-a-Service (SaaS) is all about agility, rapidly delivering innovation to customers and adapting to market changes. However, SaaS architectures pose unique DevOps challenges due to the need to manage multi-tenant deployments across different isolation models (silo, pool, hybrid). This session will explore best practices for implementing a DevOps process that enables SaaS teams to efficiently onboard and offboard new tenants while also allowing frequent application updates and uniform deployments across the tenants.
We will cover how to package applications via Helm charts and Terraform modules for consistent deployments, leveraging GitOps with Flux to maintain environments as an immutable infrastructure, automating tenant lifecycles with Argo Workflows for onboarding, updates, and offboarding, and balancing the need for agility in application delivery with operational efficiency across tenants. Attendees will gain insights into architecting a SaaS DevOps pipeline that maximizes agility and innovation while ensuring cost efficiency through unified tooling and processes. The session will provide strategies for overcoming the unique multi-tenancy challenges in developing and operating successful SaaS solutions.
Accelerating Application Delivery with OpenTofu Controller and GitOps
Developers often face challenges in reusing code and infrastructure across different projects, leading to duplication of effort and slower time-to-market. Platform engineering aims to solve this by providing a shared, standardized platform with reusable assets, automation, and governance, enabling faster development and delivery of applications.
Explore how OpenTofu Controller, in conjunction with Fluxv2 and GitOps principles, enables a seamless integration of infrastructure and application resources within a Kubernetes environment. We will dive into a real-world use case, showcasing the deployment of a multi-tenant SaaS platform on Kubernetes using OpenTofu Controller and Helm to consistently package reusable assets and deploy both application definitions and infrastructure components through a Git-centric workflow.
Cost Optimization with Karpenter and StormForge
During this session, we will discuss the differences between Cluster AutoScaling (CAS) and recently-donated-to-CNCF Karpenter. With a sample application, we will explain how we performed a bake-off between CAS and Karpenter. Finally, we will show the importance of Requests and Limits and the extra cost gains by fine-tuning Requests and Limits with StormForge SaaS optimized live.
