.NET Blog·2yIntroducing ASP.NET Core metrics and Grafana dashboards in .NET 8
ASP.NET Core in .NET 8 introduces metrics and Grafana dashboards. Metrics can be used to monitor app activity and can be displayed on a dashboard or trigger real-time alerts. There are options available for using these metrics, including the .NET Aspire dashboard and ASP.NET Core Grafana dashboards.
Unzip·2y📡 OpenTelemetry
OpenTelemetry is a standardized framework for generating and processing telemetry data. It supports distributed tracing, observability, and offers a variety of SDKs for continuous profiling, instrumentation, and exporting. It allows for standardized data collection without vendor lock-in. However, there may be potential overhead, limited support for packages without auto-instrumentation, a learning curve, and it is still an early-stage project.
DEV·2yProdzilla: From Zero to Prod with Rust and Shuttle
Prodzilla is a synthetic monitoring tool built in Rust that focuses on testing complex user flows and optimizing for human readability. The author chose Rust for its performance, predictability, and the supportive Rust community. The tool has a small memory footprint, is lightning fast, and can be hosted for free on Shuttle.
Medium·2yLessons From Our 8 Years Of Kubernetes In Production — Two Major Cluster Crashes, Ditching Self-Managed, Cutting Cluster Costs, Tooling, And More
Lessons learned from running Kubernetes in production for 8 years include the complexity of Kubernetes, the importance of managing Kubernetes certificates, keeping Kubernetes and Helm up to date, maintaining centralized Helm charts, disaster recovery planning, backing up secrets, considering vendor-agnostic vs "going all in" approaches, and optimizing node types and cost with reserved instances. Observability through monitoring, alerting, and logging is crucial, and security measures like access control and container vulnerability scanning are necessary. The company experienced two major cluster crashes due to certificate expirations. Migrating from self-managed on AWS to managed on Azure (AKS) improved ease of use, integrated Azure services, and reduced costs. Overall, Kubernetes has been a game-changer for the company, providing scalability, cost optimization, improved developer experiences, and faster time-to-market for new products and services.
