Why now?

LinkedIn Signal's Architecture - http://sna-projects.com/blog/2010/10/linkedin-signal-a-look-under-the-hood/

The community of developers whose work you see on the Web, who probably dont know what ADO or UML or JPA even stand for, deploy better systems at less cost in less time at lower risk than we see in the Enterprise. This is true even when you factor in the greater flexibility and velocity of startups.

The Good Ole Days

Put this Code Live, here's a tarball NOW!

What dependencies ?

No machines available ?

What database ?

Security ?

High Availability ?

Scalability ?

My computer can't install this ?

Devs vs Ops

10 days into operation

What High Load ? What Memory usage ?

Are these Logs ? Or this is actualy customer data ?

How many users are there , should they launch 100 queries each ?? Oh we're having 10K users

Why is debugging enabled ?

Who wrote this ? Why are we doing that?

There is a firewall b/w webserver & DB?

The filesystem is encrypted?

11 days into operations

We can solve this !

Some people think the Ops work starts on deploymentOps = both system, app as platform !

It starts much earlier

Get Devs and Ops to talk asap or keep them as one :)
