How to Run a High Traffic ( ~40 million hits) Web Farm Very Carefully Plan Outsource Test Debug Deploy Monitor

The Beginning Gopher Site – Text Files Multimedia CD-ROM 2-4 people Hosted Website on Digital News

The Real Beginning Hire a Developer or two. Build an Access DB that generates HTML files. Hire an SA. Tell him to build a website.

First Generation Find an ISP to host a single server. Pay through the nose. FTP push HTML and Image files. Build perl reporting and lead ( data ) submission scripts. Discover that this doesn’t work so well when you run radio advertising.

Scale Add more boxes. Add a real RDBMs. Add a Blackberry. Add developers, but not SA’s.

First Steps Toward an Enterprise Add an SCM System – Perforce. Use Oracle to generate static HTML pages using AOLServer, TCL, and stored procedures. Add staging environment and QA. Add 3 rd web server. Build reporting environment.

Vendor Management / Outsource Web Infrastructure Initially high dollar amount per server. Included backup, monitoring, and spare equipment Service Oriented Solution Risk mitigation contrasted by high cost.

More Traffic! Add 4-6 servers. Add better load balancing. Add point to point T1 line between hosting facility and office. Increase monitoring solution. Begin transition to J2EE platform with JRUN and live Oracle RDBMs.

Vendor Management Issues Surface Per box fee doesn’t scale. Cost of Premium Services Vendor Mistakes Mismanagement of Vendors leads to Angry Vendors

Outsourced Website Vendor Solution Emerges Negotiate Purchase of Hardware Vendor moves to co-location model for customer supplied hardware Hardware Cost Decline Begins
