What type of site is this (ecommerce, information, flat html)? Are you using an app server or specialized server (ColdFusion, J2EE, Jboss, BroadVision, Websphere)? There are many many different pieces to look at as far as hosting environment. Here are some basics. Redundancy on all tiers. Tiers having to do with, web server, application server, database server, network, power and connectivity. Otherwise you will have a single point of failure, you could get away with your web server not being redundant, but then web servers are usually the least expensive part of the system. So here are a few things to look at. Say your system is a typical ecommerce site. You'll want to gauge your architecture by looking at concurrent users, that is at any given time how many people/users/visitors making simultaneous requests of your system. Given what you are looking at I would say you going to want multiple machines, usually on multiple tiers, so your going to want multiple web servers, multiple database servers, load balanced. The 250k mailing list isn't insane, but your going to want to look at pulling that on a box of its own, and make sure you still stagger the emails. You are going to want 2-3 Admin, and good ones. dan -----Original Message----- From: thelist-bounces at lists.evolt.org [mailto:thelist-bounces at lists.evolt.org] On Behalf Of Steve Bissonnette Sent: Monday, May 24, 2004 4:10 PM To: thelist at lists.evolt.org Subject: [thelist] Help with Heavy Serving Requirements Hi Everyone, I would like to know if anyone has suggestions on a VERY GOOD host that can handle the following type of site .. 1-1.5 terabytes of transfer per month 100-150 million hits per day 10-20k emails a day a 250k mailing list and a mail server that can handle it 24/7 support and very quick (within the hour) turnaround and manage serious / constant attacks --- and truthfully, an opinion of if we should get pricing from major telecoms....?
