Yes it definitely can. You should put all types of caching mechanisms in place like memcached, zend opcache, varnish-cache. You can use w3 total cache and mix and match the caching mechanisms and test which one serves you better.
You should invest in a CDN like cloudfront or any other available alternative. You can have elastic load balancing in AWS. You should keep some EC2 instances provisioned in case you expect traffic to peak at any given period of time. You should be able to calculate that from ananlytics and past traffic growth pattern. You should be using HyperDB plugin to serve you database from multiple hosts over multiple ec2 instances (if using aws). Rest is keeping redundant backups, replications and scaling with colacation server (or in aws terms having ec2 instances multiple availibility zones). One last thing you should invest in better DNS server. That will be a great relief in long run.
