Redis Deployment

4️⃣ Where to deploy Redis? (VM / Docker / Kubernetes)

✅ Option 1 – Directly on a VM (bare-metal / cloud VM)

• Install using package manager (apt, yum)

• Simple for small to medium setups

• Use systemd service to keep it running

• You manage:

  • config

  • backups

  • upgrades

Good for: single node, dedicated server, low complexity.

---

✅ Option 2 – Docker on a VM

• Run Redis as a container:

docker run -d \
  --name redis \
  -p 6379:6379 \
  -v /data/redis:/data \
  redis:7-alpine

Pros:

• Easy to start/stop

• Easy to version control config using docker-compose

• Can run app + Redis side-by-side

Good for: dev, staging, and small production with 1–3 nodes.

---

✅ Option 3 – Kubernetes

• Redis runs as:

  • StatefulSet (for persistent identity)

  • Service (for stable access)

• Use Helm charts (Bitnami, Redis official) instead of writing all YAML yourself.

• K8s handles:

  • restarts

  • scheduling

  • rolling updates

Good for: when your whole stack is already on K8s and you know K8s basics.
