The legitimate traffic on the DDoS-Guard network has recently exceeded one hundred gigabits per second. Now 50% of all our traffic is generated by customer web services. These are many tens of thousands of domains, very different and in most cases requiring an individual approach.
Under the cut - how we manage front nodes and issue SSL certificates for hundreds of thousands of sites.
Setting up a front for one site, even a very large one, is easy. We take nginx or haproxy or lighttpd, configure according to the guides and forget. If you need to change something - do reload and forget again.
