  1. Wanadoo Portals A long-lived home-grown Linux-based low-cost leading mass-market servicePierre AUBERT & Eric OLIVERI FranceTelecom/Home Communication Services/Broadband & Internet

  2. We talk about mass market net & computer engineering • the #1 in France • a simple web page • the Big Picture : pure* Open source – Linux – PC hardware • some thoughts about the past and the future • works well, costs little  delivers more from less

  3. The #1 portals in France • wanadoo.fr – voila.fr – MMGs – IM/IRC… • 65% reach – 13 M unique visitors • 80 M pages to 4.2 M customers daily • Every day’s peaks : • 150 000 simultaneous users • 1 Gb/s Internet content • 5 000 new users/mn • 100 000 web pages/mn • transport conn/s, forks/s, SELECTs/s…

  4. We talk about mass market net & computer engineering • the #1 in France • a simple web page • the Big Picture : pure* Open source – Linux – PC hardware • some thoughts about the past and the future • works well, costs little  delivers more from less

  5. A simple web page …

  6. Mathopd Apache/C++ Apache/Oracle Solaris/Linux Apache/PHP/mySQL IIS/ASP/SQLsvr TUX LVS embedded firewalls …, but …

  7. We talk about mass market net & computer engineering • the #1 in France • a simple web page • the Big Picture : pure* Open source – Linux – PC hardware • some thoughts about the past and the future • works well, costs little  delivers more from less * well, mostly

  8. Not only a web server • Front office • Network* – Load Balancers* – Firewalls – DNS • Web servers : Apache/Mathopd/TUX, mostly PHP • Databases : mySQL, postgreSQL • Back office • Publishing – Content management • Audience collection • Databases** • Supervision, backups, etc. • * sometimes open source/Linux/PC hardware • ** most often non-open source/non-Linux/non-PC hardware

  9. other services IMAP, HTTP… BACK SERVICES databases VPN databases web farms redirect N x FRONT SERVICES DNS backups load-balcers + firewalls + routers supervision content management audiencecollection

  10. 3 ways to deliver Web service • Apache for dynamic content • Mostly PHP, some C++, some SSI • 20 M pages for 2.5 M users daily • 12 servers : Bi-CPU Intel, type 1 – 60 Mb/s • Mathopd for static content • Maximize browser cache effect • 2000 HTTP/second • 6 servers : 1-CPU Intel, type 0 – 25 Mb/s • TUX for redirection service • Built-in Linux kernel • 2500 HTTP/second – 2 Mb/s • 3 servers (1 is enough) : 1-CPU Intel, type -1 ;–)

  11. Some other services • Cookies (identity, tracking…) • 1250 HTTP/sec • 4 servers : 1-CPU Intel type 0 – 10 Mb/s • Databases : authentication • 1000 reads/mn – 150 simultaneous connections • 1 server 1-CPU 1G RAM, type 1 • Databases : search engine crawler • 500 M docs – 4 Tb – 100k writes/mn • 12 servers 2-CPU 5x72Gb each, type 1 • WAN-LAN • DNS : 4 servers 1-CPU Intel type 0 – Zebra (BGP/OSPF) • Firewall + load-balance appliance : 1-CPU Intel, type -1 • Tricks : lingerd, nscd, multicast… • tuning : 20 000 sockets per IRC server

  12. Supervision etc. • 60+ parameters per server on each of 1000 servers • Net-SNMP, big brother/big sister, Perl… • ad hoc monitoring (~ 30%) : 1 h to develop and deploy • 20 servers 1-CPU Intel, type 1 • At-the-fly graph generation : 50 000 parameters • 300+ samples/s – 3 servers Bi-CPU Intel, type 1 • RRD-Tool + SNMP managers (Perl) + Apache • Env – Network – from HW&CPU to application internals • Backups, storage • Amanda’s self-planning, no routine restore  1/10th FTE • 2 servers P2-400MHz 2,4To (2€/GO/y)– cheaper than tape : (6€/GO/y) • backs up daily 300 servers

  13. We talk about mass market net & computer engineering • the #1 in France • a simple web page • the Big Picture : pure* Open source – Linux – PC hardware • some thoughts about the past and the future • works well, costs little  delivers more from less • * well, mostly

  14. Lessons from the past • Choose what fits best • 1996 : from FreeBSD to Solaris • 2003 : from Solaris to Linux • voila.fr launched 1998 : Apache/PHP/Linux • Service first • system administrators are front-line • diagnose and fix fast (or alternate service/systems) • end-user satisfaction = systems health • accounting transparency (CAPEX & OPEX per server/day)

  15. Lessons from the past • PC hardware is a key factor • Failures are facts not problems • « Small is beautiful » : cost of redundancy is 1/N • Competitive mass market sourcing • PC operating system is hw-independent • Reuse – assemble components • Open source OS is a key factor • Best use of hardware resources • Flexible kernels – Excellent network support • Application level • Open source platforms – Internet applications • Interoperability is in DNA

  16. Lessons from the past • Design – skills • Not a sequential « product » process • Expert staff allow short & long term savings • Efficiency • Low-range (90%) = 3 to 5 k€/year • High-end PC servers cost 5+ times more • Mid-range Unix servers cost 20+ times more • Numerous distributed small systems • scale at front office • keep back office + infra stable • distribute bandwidth, IO buffers, axis…

  17. We talk about mass market net & computer engineering • the #1 in France • a simple web page • the Big Picture : pure* Open source – Linux – PC hardware • some thoughts about the past and the future • works well, costs little  delivers more from less • * well, mostly

  18. Costs little • Some figures • 1 system administrator for 40 servers • 1 low-range server = 3 to 5 k€/year OPEX • Per unique visitor : 1 €/year • Per 1k web pages : 0.5 € • margin cost = 2 c€ OPEX, 3 c€ CAPEX • Cost breakdown – OPEX • 15% shell & core • 15% hardware • 15% bandwidth • 5% maintenance/support • 50% man power

  19. Costs little = « works » well • Home page Solaris • 12 Sun 4-CPU : 6 dynamic + 6 static content • 400 k€/year OPEX (amort. included) • Additional CAPEX : 10 € per 1k daily pages • Home page Linux • 18 PC 1&2-CPU : 12 dynamic + 6 static content • 100 k€/year OPEX (amort. included) • Additional CAPEX : 3 € per 1k daily pages works well

  20. Works well • Voila.fr ranked* #1, Wanadoo.fr ranked* #3 • (*) Google’s home page always #1… but that’s not a real portal home page • Both fastest real portal home pages • Unavailability mostly due to a sub-service : • freeware expensive : fees + maintce + poor support • Open source proprietary code : can’t fix This sub-service delivers less from more ;–)

  21. Next Steps • Convince top management that Open-Source solutions can replace proprietary one! • Most agree on web front office (1-tier) • Most disagree on 2nd tier: Jonas,Jboss / Websphere, 9iAS • All disagree on DB: MySQL, PostgreSQL / Oracle, DB2, SQLs • Carefully select an appropriated database for your needs • Deploy Oracle on PC + Linux+ attached disks (Instead of Sun + Solaris + SAN or NAS :)
