What Comes First, User Experience or Software Architecture?



Do you architect the system (Database, Services, etc.) first and then build the user experience for your end user clients (Mobile Apps, Web Apps)? Or Are you the kind of engineer that design the user experience first and let it drive the rest of system? We talk about advantages and disadvantages of both!


We are using Instagram as a use case in our analysis.

Enjoy
Stay Awesome

Vlog - Persisted Connections

HAPPY HOLIDAYS! Today’s vlog topic is about persisted connections, advantages, disadvantages specially while writing applications that hit the database. Should you keep those tcp database connections alive? or should you close them as soon as you are done with your requests.  We also discuss how persisted connections can actually lead to DDOS (distributed denial of service) attacks if managed incorrectly.
