At the time, count was +- 10
Lots of firefighting!!!
Very difficult to scale
Instance count
Not a lot of changes to pic, but BIG changes under the covers.
Replaced Varnish with CDN
Widget : Snippets of code.
Load last.
Less load for us to worry about, as CDN takes care of it.
Static content.
Could we build it : YES
Did we have time or the need to : NO!!!
We could build this ourselves, but didn’t have the need as basic CDN functionality met our requirements straight off the bat.
Count compared to 10 from old stack

1:1 relation.
