This setup will be for a purely PHP based video website, running a CDN for the video storage/bandwidth. Projecting very fast growth for the site.
Which do you think is better/wiser? In terms of performance, redundancy, security, scaling, etc.
1. Two 4GB Linode servers (One MySQL, One Apache'PHP).
2. Four 2GB Linode servers (Two MySQL, TWO Apache'PHP, linked together via Two Nodebalancers).
The costs for the servers will be exactly the same for both setups, BUT the Four server setup will cost more due to needing 2 Nodebalancers + More backups + more maintenance time, and possibly the Linode Managed service.
Want to set it up right from the start, so scaling is a breeze later, and performance/uptime is critical. Which setup would you go with?
