ec2 node type preferred:

Family: Memory Optimized. R5a instances are well suited for memory intensive applications such as high performance databases, distributed web scale in-memory caches, mid-size in-memory databases, real time big data analytics, and other enterprise applications. Cost: 0.072 per instance per hour for OD - 52.56 USD / month Storage: gp2 SSD based EBS volume - 20 GB (2.28 USD / month)

Redis server replicas: 2 [need to verify if redis helm chart supports a master/slave or a backup replica feature on k8s] - this would also mean two EBS volumes instead of one.

For monitoring set-up with prometheus-stack, update this in the values file as well:

  enabled: true
	extraArgs:
    skip-tls-verification: true
  prometheusRule:
    enabled: true
    namespace: prometheus-46xitb-srgcgk #namespace where Prom Stack is deployed
  serviceMonitor:
    additionalLabels:
      release: my-release #prom stack release name
    enabled: true
    labels:
      release: my-release #prom stack release name
