3. What
should
you
take
away
from
this
presentaEon?
• What is Stratos?
• Why is an Open
PaaS important?
• How can I try out Stratos?
– On the Web?
– On your machine?
• What services does Stratos provide?
• Where can you get more informaRon?

4. Moore’s
Law
for
Data
• The amount of data online went from
– 5 exabytes in 2002
– 281 exabytes in 2009
• Doubling every 15 months
• You cannot deal with this data growth with
the same applicaRons
– A reasonable conclusion is that the number of
applicaRons will double every 15 months too

7. Stratos
Overview
• Stratos – an Open Source project / product
– A full middleware plaorm available as a service, with
self service
• Fast provisioning
– Based on OSGi
• Modular, componenRzed, standard
– MulR-­‐tenant, ElasRc, Metered and Billed
• EffecRve and powerful
– Available under the Apache License
• Open Source, Open License, Open Development
• StratosLive
– a Plaorm-­‐as-­‐a-­‐Service

9. InstallaEon
opEons
• 1. Full installaRon (like StratosLive)
– Pre-­‐reqs
• IaaS – Eucalyptus, vmWare, Ubuntu or Amazon
• MySQL & Perl & JVM
• Ability to run a number of VMs (one per service)
• 2. Laptop/Simple install (on my laptop)
– Pre-­‐reqs
• A machine with lots of memory (4Gb min, 8GB
preferred)
• JVM
• MySQL & Perl

10. InstallaEon
of
Stratos
1.5.1
pack
• Config mysql
– max_allowed_packet = 16M
• ulimit –n 65000
• Unzip the distro
• cd stratos
• ./stratos-­‐setup.pl
• export STRATOS_DIR=`pwd`/deploy
• cd deploy
• ./stratos.sh start all
10

11. Deploy
a
webapp
h8p://stratoslive.wso2.com

12. Isn’t
something
missing?
• APIs and Services
• You can’t just run a webapp
• You need:
– Data
– Messaging
– Logging
– What else?

13. JDBC

Stratos

14. Cassandra

15. Hector
API
/**
* Insert a new value keyed by key
* @param key Key for the value
* @param value the String value to insert
*/
public void insert(final String key, final String value) throws ExcepRon {
execute(new Command(){
public Void execute(final Keyspace ks) throws ExcepRon {
ks.insert(key, createColumnPath(COLUMN_NAME), bytes(value));
return null;
}
});
}

16. What
are
the
dimensions
to
evaluate
a
PaaS?
• Which languages and APIs does it support?
– (Are you locked in?)
• Is it available to run on a private cloud?
– (Are you locked in?)
• Which services does it offer?
– (Are you locked in?)
• Is it Open Source?
– (Are you locked in?!)
16

17. Who
are
the
other
players
in
the
PaaS
market?
• Those without a Private PaaS
– Force.com and Heroku
– Google App Engine
– Amazon ElasRc Beanstalk
• Those with a Private / Public PaaS
– Tibco
– Microsox
• Those with an Open Private / Public PaaS
– SpringSource CloudFoundry
– WSO2 Stratos

18. Available
Services
in
Stratos
(a
selecEon)
18

19. Available
Services
(low
level)
• MulR-­‐tenancy
• Deployment synchronizer
• ElasRc Load Balancer
– tenant-­‐aware
• Tenant-­‐aware idenRty manager
– SAML2, OpenId, Oauth, XACML
• Tenant Metering and Billing
• Discovery
• Logging
• ConfiguraRon & Repository
• Data-­‐as-­‐a-­‐Service
• Queueing-­‐as-­‐a-­‐Service
• Health Monitor
• Private / Public Cloud bridging
19

20. Every
Service
has
a
network
API
• All admin funcRons and all the low level services
are available as SOAP APIs
– Full SOAP support, REST in some cases
– Always possible to bridge into REST using the ESB
• Why?
– Clear SOA design
• Allow mashups, BPEL and ESB integraRon
– Automated provisioning
– Support
hybrid
mulE-­‐tenancy
models
for
legacy
soVware
20

21. MulE-­‐tenancy
• Every service can support mulRple tenants in the same
container
– Higher efficiency, lower resources
– Can be split tenant per-­‐VM using the MT-­‐aware Load Balancer
• IsolaRon includes classloaders, code signing and Java
security policies
– Cross-­‐tenant sharing is via the network (REST, SOAP, etc)
• Every tenant has all services by default but they can be
turned off
• You can deploy webapps that are available to all tenants

25. Examples
and
Case
Studies
• System Integrator
– Currently running Stratos for internal projects
– Examining the use of Stratos for customer projects and SaaS
• Home Loan Bank
– WSO2 runs a private deployment of Stratos
– Developer sandbox and test environment
– Currently apps are then deployed internally in Carbon
• Niche PaaS
– CombinaRon of cross tenant services / APIs
– Allow each tenant to deploy / customise the logic
• Mobile PaaS
– Building a PaaS environment for a mobile telco
• SaaS-­‐enablement of legacy applicaRons

• Mobile
– Working to provide Mobile PaaS
• VerRcal industry iniRaRves
– E.g. FIX/HL7 in the Cloud
• End-­‐to-­‐end automated governance and development
• Pure VM deployment and management
• Super-­‐scale shared nothing

28. What
to
take
away
with
you
• Look at the lock-­‐in points
• What services do you need now, and in the
future
• Try some out PaaS’s now
• Even if its too early for your main
producRon, it might suit some part of your
deployment
