- 1. Difference Between StatefulSet and Deployment in Kubernetes A Comparative Overview www.visualpath.in +91-7032290546
- 2. Introduction to Kubernetes Workloads Kubernetes provides multiple ways to manage application workloads. Two major controllers: Deployment and StatefulSet • Choosing the right one depends on the app’s needs (e.g., stateless vs. stateful). www.visualpath.in +91-7032290546
- 3. What is a Deployment? Designed for stateless applications Manages ReplicaSets and ensures the desired number of pods are running. Supports rolling updates, rollback, scaling • Pods are interchangeable – no identity retained. www.visualpath.in +91-7032290546
- 4. What is a StatefulSet? Designed for stateful applications like databases. Each pod has a unique identity (name + persistent volume). Pods are created, scaled, and deleted in order. • Used when persistent storage and identity are required. www.visualpath.in +91-7032290546
- 5. Key Differences (Tabular Format) Feature Deployment StatefulSet Pod Identity Not preserved Unique, stable Pod Names Random Predictable (pod-0) Volume Persistence Shared / Ephemeral Dedicated, persistent Scaling Order Parallel Sequential Use Case Stateless apps Stateful apps www.visualpath.in +91-7032290546
- 6. Use Cases for Deployment Web frontends (NGINX, React, etc.) REST APIs Microservices without local state • Background jobs www.visualpath.in +91-7032290546
- 7. Use Cases for StatefulSet Databases (MySQL, PostgreSQL) Queues (Kafka, RabbitMQ) Clusters with leader election (ZooKeeper, etcd) • Applications that need sticky identity. www.visualpath.in +91-7032290546
- 8. Visual Comparison Diagram Side-by-side illustration: o Deployment: Pod replicas all equal, ephemeral o StatefulSet: Pod replicas with identity & volume (Use visuals to enhance understanding — Kubernetes pod icons, etc.) www.visualpath.in +91-7032290546
- 9. Summary and Takeaway Deployment = stateless, interchangeable pods StatefulSet = stateful, stable pods with identity Choose based on whether your app needs storage and identity • Understanding this helps in designing scalable and reliable apps in Kubernetes. www.visualpath.in +91-7032290546
