WSO2 Platforms and Data
§ 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!

Multi-Tenant Data Needs
§ If super tenant is wri<ng a mul<-‐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

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

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

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
