15. What is Cassandra?
• Apache Cassandra http://cassandra.apache.org/
• NoSQL column family implementation
• Highly scalable, available and no single point of failure.
• Very high write throughput and good read throughput.
• SQL like query language (from 0.8) and support search
through secondary indexes
• Tunable consistency and support replication
• Loose/Flexible Schema

16. Cassandra Approach
Table Data Items
Books “Foundation” -> (author=asimov, rank=9, price=14, tag1=“sci-fi” tag2=“future”)
“I Robot” -> (author=asimov, rank=7, price=14, tag1=“sci-fi” tag2=“robots”)
Tags2Books “sci-fi” -> 1311031405918=“Foundation”, 1311031405919=“I Robot”
“future” -> …
Tags2Authors “sci-fi” -> 1311031405920=“Asimov”
“future” -> …
Comments “Foundation” -> (1311031405922=“best book-sanjiva”, 1311031405923=“well I
disagree-srinath”)
“I Robot” -> (1311031405924=“Asimov’s best-srinath”, 1311031405928=“I like
foundation better-sanjiva”)
Ranks Rank -> (9=“Foundation”, 7=“I Robot”)

26. BAM2 Architecture

27. Data Publisher API (draft)
Event event = new Event();
event.setCorrelation(createCorrelationMap());
event.setEvent(createEventDataMap());
event.setMeta(createMetaDataMap());
EventReceiver eventReceiver = new EventReceiver();
eventReceiver.setSocketTransportEnabled(true);
eventReceiver.setUrl("https://localhost:9443/");
eventReceiver.setUserName("admin");
eventReceiver.setPassword("admin");
eventReceiver.setPort(7611);
ArrayList<Event> events = new ArrayList<Event>();
events.add(event);
BasicConfigurator.configure();
setTrustStoreParams();
AgentConfiguration configuration = new AgentConfiguration();
Agent agent = new Agent(configuration);
agent.publish(events, eventReceiver);
agent.shutdown();

33. Vertical PaaS
Users
Partners
Tenant Tenant Tenant Tenant
Apps Apps Apps Apps
Ecosystem Owner
PaaS / Stratos
API Management / API Store
Existing business systems as APIs

34. Automated Cloud Development
• Integrating Redmine, JIRA, SVN, Governance Registry,
Maven, Stratos and IS together with BPS+ESB
– Creating a project in Redmine creates SVN, Stratos Project,
and populates users
– Checking in a project into SVN with “Deploy” tags initiates
a review process in BPEL
• Automatically creates JIRA entries for code review, security review
• When these are closed, the process progresses through staging
• Eventually the project is automatically deployed into production
cloud
• Planned for inclusion in StratosLive in 2012
– Can be customized for your environment and projects
