WSO2 Platforms and Data

18. WSO2 Platforms and Data StratosLive WSO2 Carbon
We didn’t really have to think about it much initially
Users have their ways to manage data
However, users do want and need a polyglot data architecture
WSO2 Stratos
In a multi-tenant environment, how to safely and scalably store and retrieve data is not something that can be left to the user!
Some data may not be in the PaaS – still in the enterprise
StratosLive
This is our living problem! 18

19. User experience of Stratos

20. Multi-Tenant Data Needs
If super tenant is writing a multi-tenant app
Super tenant responsible for proper isolation / security
Can use any storage technology
If other tenant
Needs private storage in a secure, scalable manner
Scale can mean for lots of tenants or lots of load by a given tenant 20

21. Achieving Tenant Isolation
Each Tenant is given a Security Domain
Each domain may have its own User Store and Permissions, thus have a set of users and permissions enabling users to access resources
Each domain is isolated and do not have access to other domains 21

22. Accessing Enterprise Data from PaaS
Many cloud apps will still need to “call home”
Private enterprise data may need to remain on- premise
E.g. EU privacy laws
Better approach is to have controlled exposure of enterprise data
Use Data Services
WSO2 Cloud Services Gateway safely connects private data services into the cloud

23. Summary
WSO2’s middleware products are in fact built as one product sharing a single codebase
Data needs vary depending on usage model (single vs. multi-tenant) and deployment environment (on-premise, private-cloud vs. public-cloud)
No single answer will satisfy all needs
