WSO2 Platforms and Data

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!

User experience of Stratos

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

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
