6 Who is Railo for? 6

7 Who is Railo for? 7 Complexity

8 What do I get with Railo? Tons of features out of the box Full featured caching Web services Charting ORM Messaging, Flash remoting Great performance, with AS7 8

9 Performance 9

10 Some Railo examples Get a resultset from the Database <cfquery name="getnotificationusers" datasource="#sdbnewsletter#"> SELECT s. , s.firstname, s.lastname, s.keywords, sd.updatepathid, s.subscriberid FROM subscribers s INNER JOIN subscriptiondetails sd ON s.subscriberid = sd.subscriberid WHERE s.confirmed = 1 ORDER BY s.subscriberid </cfquery> <cfdump eval=getnotificationusers> 10

11 Some Railo examples Writing a file to an FTP server <cffile action= write source= /var/www/text.txt destination= ftp://user:pass@sotr.railo.ch/text.txt > Writing a file to Amazon S3 <cffile action= write source= /var/www/textfile.cfm destination= s3://key:secretkey@ > 11

12 Some Railo examples Creating a webservice <cfcomponent> <cffunction name= showstock returntype= struct access= remote > </cffunction> </cfcomponent> <cfcomponent> <cffunction name= showstock returntype= struct returnformat= JSON access= remote > </cffunction> </cfcomponent> 12

20 Solution? 20

21 Is clustering the right solution? photo by Jean-Michel Lunati 21

22 Why avoid clustering? 22

23 What to do before clustering? 23

24 Real life example This is from my own experience (dated 2000) Client investigated the use of a CMS which only managed 4 req / s Requirement: 5,000,000 req/month 20 days, 10 hours, 3600 seconds Requirement: 14 req/s ON AVERAGE! 24

25 Real life example To handle peaks, multiply by 5 we needed 70 req/s The setup managed 4 req/s / server 25

26 Cost calculation 26 This was more or less the offer by the CMS vendor

27 Performance tuning Considerations In 90-95% of the cases the app is the problem not the hardware or used software No caching, no JVM knowledge Old programming habits, bad coding 27

28 How to use the cache in Railo? <cfquery name= name datasource= dsn cachedwithin= #createtimespan(0,0,15,0)# > Select </cfquery> <cfcache action= content key= susi cachedwithin= #createtimespan(0,0,15,0)# > Generated <b>html</b> </cfcache> 28

29 Ready to cluster? 29

30 Most common problem? 30

31 Let s scale it in the cloud 31

32 How does it start? 32

33 Something happens 33

34 How is Kuorum clustered? Railo features (involving Infinispan) allow a very easy setup Identical AMI Infinispan Session cluster Infinispan Cluster cache 34

35 Perfect cluster setup? 35

36 Example - Linkdrop Runs Tomcat 6 with Apache on Fedora Uses a cache server Completely dynamic server setup 36

37 Linkdrop 37

38 Technologies Uses JBoss AS 7 Beta 4 Uses sexy Infinispan CR1 Railo Infinispan HotRod Client 38

39 JBoss / Infinispan on EC2 One Amazon AMI Infinispan image One Railo image Railo cache uses the Infinispan cluster via HotRod client. Sessionstorage enabled Auto-scaling enabled 39

40 Configure Railo for AS7 jboss-deployment-structure.xml 40

41 Setting up AS7 for EC2 41

42 Deploying in the cloud Amazon EC2 Microsoft Azure CloudBees with Railo support Deployment with Hudson/Jenkins & for easy development and deployment 42

43 Examples myswitzerland.com Uses the cloud for video conversion stored on Amazon S3 43

44 Examples myswitzerland.com 44

45 Examples Technorati 14 billion requests / month (14,000,000,000 req/m) up to 3500 req/s -> 700req/s & server connection between the app server and the loadbalancer is kept open 7 Railo cloud servers, 1VCPU 1GB RAM. Citrix Netscaler VPX loadbalancer 45

46 Examples Technorati Bandwidth at peak - 77 Mbit/s Server connections at peak 1020 Client connections at peak Requests per second at peak
