#devsum15
So...
@ulfbjo [email protected]
USE COMMON SENSE
The developer should be in control, not the framework
#devsum15
What to do?
@ulfbjo [email protected]
- We build one protocol and then adapt each client to use it…
- Or we allow clients to talk to each other “cross-protocol”
#devsum15
Then there is STATE!
@ulfbjo [email protected]
- STATE is important! If you do not know the clients you do not know who to send to.
- We have full duplex connections, use STATE
- STATE will reduce development time
- STATE will decrease the size of your messages
- STATE will reduce the complexity of your application

The fake unicorn way
@ulfbjo [email protected]
The question is not if things will change, it's only a matter of when they will change.. Make sure you have the flexibility to adapt when changes
come!
Be in control of your transports!
Might work just fine...
