The document discusses scalability, defined as the ability of a system to handle increased workloads and grow accordingly. It highlights various components and concerns related to scalability, including performance, infrastructure, and engineering culture. The takeaway emphasizes the importance of creating broader systems rather than merely enhancing speed, illustrated by a quote from Steve Swartz.

1. SCALABILITY

2. THE TERM
Scalability is the capability of a system, network,
or process to handle a growing amount of work,
or its potential to be enlarged to accommodate
that growth.

15. TAKE AWAY
“When you are stuck in a traffic jam with
a Porsche, all you do is burn more gas in
idle.
Scalability is about building wider roads,
not about building faster cars.”
— Steve Swartz
