5 Let s talk about From Wikipedia: Enterprise Content Management (ECM) is any of the strategies and technologies employed in the information technology industry for managing the capture, storage, security, revision control, retrieval, distribution, preservation and destruction of documents and content. ECM especially concerns content imported into or generated from within an organization in the course of its operation, and includes the control of access to this content from outside of the organization's processes. In Short: All the things an enterprise needs to manage their homepages. 5

8 Homepages that are not part of the system e.g. 8

9 numbers that matter Page impressions measured for the ECM at DB Group per month Intranet for more than 60,000 users: 2,500,000 Internet worldwide accessible: 7,500,000 Internet sites for more than 30 subsidiaries: 3,500,000 overall 13,500,000 9

10 Let s see what s inside What system can handle this amount of traffic? From hand truck to SUV in 3 steps. 10

11 2000 to 2002 the very beginning simple one-line architecture availability through one system stand by software Sun Solaris, Apache, Perl (CGI) 55,000 Intranet users 11

12 Pretty straight and simple LoadBalancer Web Web CGI Perl CGI Perl 12

13 2002 to 2004 getting bigger expanded three-line architecture and clustered database system availability through redundant lines, clustering software - Sun Solaris, Apache, BEA Application, Oracle RAC 60,000 Intranet users various new features for editors 13

14 It s starting to look more interesting now LoadBalancer Web Web Web Application Application Application DBMS - Cluster 14

2004 till now The mechanics would say advanced architecture featuring: separated sets of lines for Intranet, Internet and editors clustered database system

15 2004 till now The mechanics would say advanced architecture featuring: separated sets of lines for Intranet, Internet and editors clustered database system monitoring with Nagios software - Sun Solaris (Linux), Apache, Tomcat, Oracle RAC 65,000 Intranet users Internet including 30 sub sites completely new CMS software base 15

16 State of the Art! Internet DMZ LoadBalancer Web Web Web Web GSB NAS- Intranet & Internet content not in cache Application Content- Cluster Master- Cluster Veritas Cluster LDAP DBMS Cluster Web Web LoadBalancer Web Application Application Web dynamic content Web LoadBalancer Web Intranet Editors 16

17 Small kids small problems, big kids big problems. The more parts a system is made of, the more things can break. But a problem known is a problem half solved. 17

18 more probes than any mechanic will ever need Open Source monitoring tool informs the admin of network problems before: end users managers do. monitoring daemons run checks on hosts and services problem info is then sent to a cockpit system Customized to a complex environment it looks like: 18

19 Monitoring with Nagios what the mechanics love to look at 19

In-house Nagios customizations in detail more than 5,500 checks currently in use implementation as cascading and redundant probe-system thus increasing availability ability

20 In-house Nagios customizations in detail more than 5,500 checks currently in use implementation as cascading and redundant probe-system thus increasing availability ability to check systems across network boundaries automated configuration and update for probes The system is operated by 2 employees which need only 10% of their time for this job. 20

21 Lessons Learned Experience is what you get when you don t get what you want. 21

22 Dynamic Content slow drivers in the rush hour Welcome Mr. personalized content In the news: content that changes frequently Pages have to be rerendered every time Reuse of cached pages is not possible Sophisticated caching is necessary dynamic data means heavy workload for the engines final data throughput is very hard to predict 22

23 Open Source Software No Sweat! Web : Apache Application : Tomcat Monitoring: Nagios Operation System: Linux OS is quite grown up and ready for professional use! 23

24 One for all all in one. Intranet + Internet + many sub sites = one system additions and increased workload rest on many shoulders, quick to expand, same look and feel for all 24

25 Next steps what is planned for the future? Migration of all homepages of the DB Group additional sub sites Additional 4,000,000 page impressions every month! 25

26 The End When you aim for perfection you discover it is a moving target. 26
