Observability & Monitoring

HPA automatically scales the number of pods in a deployment based on CPU utilization, memory usage, or custom metrics. Modern HPA implementations work seamlessly with KEDA for event-driven autoscaling, enabling your applications to respond dynamically to workload changes.

Service meshes like Istio and Linkerd provide advanced traffic management, security, and observability features. They enable zero-trust networking, automatic mTLS, and sophisticated routing capabilities while maintaining transparency to your applications.

Service Level Objectives (SLOs) define reliability targets for your services. Tools like Keptn automate SLO validation and enable data-driven deployment decisions, ensuring your applications meet performance and reliability requirements.

Helm simplifies Kubernetes application deployment through templating and package management. Modern Helm charts include comprehensive monitoring configurations, making it easier to deploy observable applications with built-in metrics and logging.

Effective RCA in Kubernetes requires correlation between metrics, logs, and traces. Tools like Jaeger for distributed tracing, combined with Prometheus metrics and Grafana Loki logs, provide the complete picture needed for rapid issue resolution.

Prometheus serves as the foundation of Kubernetes monitoring, providing metric collection, storage, and alerting. When combined with Thanos, it scales to handle multi-cluster deployments and long-term metric retention.

Grafana transforms raw metrics into actionable insights through customizable dashboards and alerting. Its integration with Kubernetes enables automatic service discovery and dynamic dashboard generation.

Loki provides log aggregation designed for cloud-native environments. Unlike traditional log management systems, Loki indexes only metadata, making it cost-effective and highly scalable for Kubernetes workloads.

Open Policy Agent (OPA) enables fine-grained policy enforcement across your Kubernetes cluster. Policies can govern everything from resource allocation to security configurations, ensuring compliance and operational consistency.

Argo CD and Argo Rollouts enable GitOps-based deployment workflows with progressive delivery capabilities. Automated rollbacks, canary deployments, and blue-green deployments reduce deployment risks while maintaining velocity.

The Datadog Agent provides comprehensive Kubernetes monitoring with automatic service discovery, distributed tracing, and log collection. Its native Kubernetes integration offers deep visibility into cluster health and application performance.

Istio provides a comprehensive service mesh solution with traffic management, security policies, and observability features. Its sidecar proxy architecture enables advanced routing, circuit breaking, and security without application changes.

Keptn automates SLO-based quality gates in your deployment pipeline. It evaluates service performance against defined objectives and can automatically trigger rollbacks or approvals based on SLO compliance.
