ersistent compute objects, or PCOs, are light-weight, event-based, cloud-hosted virtual machines that persistently store data and provide a programming model. PCOs represent a possible post-web architecture that supports privacy-by-design, breaks down application silos, and models real-world circumstances. This talk will present a model for PCOs based on standard Web technologies.

16. Why do this?
Orthogonality and modularity are
powerful: network effects!
More flexible
Less work
Less expensive

17. What you will see...
1. An app (could be running anywhere) using a personal
cloud
2. App uses data, connections, and functionality of the
personal cloud
3. App does not store passwords, user data, etc.
4. Connections in personal cloud are used for evergreen
contact information
5. Personal clouds can be running on different servers
6. Connection types control access

18. What you won’t see
1.KRL - use your favorite language
2.Databases - forget the hassle of user
data

22. The primary purpose of the
app is user interface and
business logic.

23. Forever is just one app.
Personal clouds can support
any number of apps doing
myriad things.

25. We used only the data (CRUD) services
Other important services include
Notifications
Subscriptions
More…
These services distinguish CloudOS
