This document discusses WSO2 Stratos, an open source public and private Platform as a Service (PaaS). It provides an overview of Stratos, including what it is, why an open PaaS is important, how to try it out, the services it provides, and where to find more information. Installation options and steps for setting up Stratos on a single machine are also covered.

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

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

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

11. Deploy
a
webapp

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

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 {

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?!)

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)

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

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
