Small websites

and the 10 minute Docker demo

Catalyst

Docker is not yet a given on production systems
Most examples concentrate either on dev (1 container) or crazy webscale shit (Google, Netflix)
There's an inbetween space that doesn't get much air time
That's what we're doing today

Anyone not heard of Docker?

virtualized hardware: good for compatibility and security, shit for performance.

virtualized OS: more restrictive of compatibility, pretty good for security, great for performance.

System calls get passed through from the guest to the host with very little interference, while still maintaining good isolation (namespaces, etc).

What is

small?

1—2 apps (plus cron jobs)

housed on 1 server (or 1+1)

with a dedicated database.

So
what's
the

demo?

Start with trivial web app that does something simple with a database
Put app behind a LB and allow it to scale sideways
Put LB behind a WAF
