    Simplifying Kubernetes deployments with a unified Helm chart, with Calin Florescu

    Managing microservices in Kubernetes at scale often leads to inconsistent deployments and maintenance overhead. This episode explores a practical solution that standardizes service deployments while maintaining team autonomy. Calin Florescu discusses how a unified Helm chart approach can help platform teams support multiple development teams efficiently while maintaining consistent standards across services. You will learn: Why inconsistent Helm chart configurations across teams create maintenance challenges and slow down deployments How to implement a unified Helm chart that balances standardization with flexibility through override functions How to maintain quality through automated documentation and testing with tools like Helm Docs and Helm unittest Sponsor This episode is sponsored by Learnk8s — get started on your Kubernetes journey through comprehensive online, in-person or remote training.

    Black box vs white box observability in Kubernetes, with Artem Lajko

    Platform Engineer Artem Lajko breaks down observability into three distinct layers and explains how tools like Prometheus, Grafana, and Falco serve different purposes. He also shares practical insights on implementing the right level of monitoring based on team requirements and capabilities. You will learn: How to implement the three-layer model (external, internal, and OS-level) and why each layer serves different stakeholders How to choose and scale observability tools using a label-based approach (low, medium, high) How to manage observability costs by collecting only relevant metrics and logs Sponsor This episode is sponsored by Learnk8s — get started on your Kubernetes journey through comprehensive online, in-person or remote training.

    Topology-aware routing: balancing cost savings and reliability, with William Morgan

    In this episode, William Morgan, CEO of Buoyant, explores the complex trade-offs between cost optimization and reliability in Kubernetes networking. The discussion focuses on Topology-aware routing and why its implementation might not be the silver bullet for managing cross-zone traffic costs. William shares practical insights from real-world implementations and explains why understanding these trade-offs is crucial for platform teams managing multi-zone Kubernetes clusters. You will learn: How Topology-aware routing attempts to reduce cross-zone traffic costs but can compromise reliability by limiting inter-zone communication Why Layer 7 load balancing offers better traffic management through protocol awareness compared to topology-aware routing's Layer 4 approach How HAZL (High Availability Zonal Load Balancing) provides a more nuanced solution by balancing cost savings with reliability guarantees through intelligent traffic routing Sponsor This episode is sponsored by Learnk8s — get started on your Kubernetes journey through comprehensive online, in-person or remote training.

    Which Kubernetes PostgreSQL operator should you choose?, with David Pech

    Are you running PostgreSQL on Kubernetes and need to choose the right operator? In this episode, David Pech, Staff Cloud Ops Engineer, shares his experience implementing database platforms on Kubernetes and guides teams through operator selection and platform requirements. You will learn: The core requirements for a PostgreSQL platform on Kubernetes, including autopilot capabilities, security practices, and observability How to evaluate PostgreSQL operators based on their architecture — from single-instance deployments to cloud-native implementations What teams should consider before building their own database-as-a-service and common pitfalls to avoid The distinction between being production-ready (running single instances) versus platform-ready (operating at scale with proper tooling) Sponsor This episode is sponsored by Learnk8s — get started on your Kubernetes journey through comprehensive online, in-person or remote training.

    Exploring multi-tenancy for my Kubernetes learning platform, with Stefan Roman

    Stefan Roman shares his experience building Labs4Grabs, a platform that gives students root access to Kubernetes clusters. He discusses the journey from evaluating simple namespace-based isolation to implementing full VM-based isolation with KubeVirt. You will learn: Why namespace isolation isn't sufficient for untrusted users and the limitations of tools like vCluster when running privileged workloads. How to use KubeVirt to achieve complete workload isolation and the trade-offs. Practical approaches to implementing network security with NetworkPolicies and managing resource allocation across multiple student environments. Follow Stefan's journey from simple to complex isolation strategies, focusing on the technical decisions and trade-offs he encountered.

    Optimize the Kubernetes dev experience by creating silos, with Michael Levan

    Michael Levan explains how specialized teams and smart abstractions can lead to better outcomes. Drawing from cognitive science and his experience in platform engineering, Michael presents practical strategies for building effective engineering organizations. You will learn: Why specialized teams (or "silos") can improve productivity and why the real enemy is ego, not specialization. How to use Internal Developer Platforms (IDPs) and abstractions to empower teams without requiring everyone to be a Kubernetes expert. How to balance specialization and collaboration using platform engineering practices and smart abstractions Practical strategies for managing cognitive load in engineering teams and why not everyone needs to know YAML.

    Rebuilding my homelab: suffering as service, with Xe iaso

    Xe Iaso shares their journey in building a "compute as a faucet" home lab where infrastructure becomes invisible and tasks can be executed without manual intervention. The discussion covers everything from operating system selection to storage architecture and secure access patterns. You will learn: How to evaluate operating systems for your home lab — from Rocky Linux to Talos Linux, and why minimal, immutable operating systems are gaining traction. How to implement a three-tier storage strategy combining Longhorn (replicated storage), NFS (bulk storage), and S3 (cloud storage) to handle different workload requirements. How to secure your home lab with certificate-based authentication, WireGuard VPN, and proper DNS configuration while protecting your home IP address.
