Architecture deep-dive WSO2 Platforms and Data

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

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

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

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
