Service-wise, for a redundant and scalable setup, you’ll probably want these:
- Load balancer + Firewall
- 2x proposer API (4 CPU, 1GB RAM)
- 2x builder API (2-4 CPU, 1GB RAM)
- 2x data API (1 CPU, 1GB RAM)
- 2x website (1 CPU, 2GB RAM)
- 1x housekeeper (2 CPU, 1GB RAM)
- Redis (1GB)
- Postgres DB (100GB+)
- A bunch of beacon-nodes (3 for redundancy?)
- Block validation EL nodes
