We weren’tready

Where did we go wrong?

AWS ismore than a toolset

AWS ismore than just a different source

of servers

Let’s get back to that...

“Legacy”

1 a legacy of the wars: CONSEQUENCE, effect, upshot, spin-off, repercussion, aftermath, by-product, result.

2 a legacy from a great aunt: BEQUEST, inheritance, heritage, endowment, gift, patrimony, settlement, birthright; formal benefaction.

Homeostasis

Metabolize toxic substances

Blood water level,re-absorption of

substances into blood, excretion

“An inability to maintain homeostasis may lead to death or a disease, a condition known as homeostatic imbalance.”

What is a cell?

What is a system?

tiny components

Kill and replace cells regularly

forces you to work with small components

Force heterogeneity

if it’s hard to do (rewrites) do it all the time

Servers are replaceable

Add and remove at will

Add and remove at will

Spot instances are killed automatically by the system

AWS ismore than a toolset

AWS isis an architectural mindset

I wish your applications

and your infrastructure a long and healthy life
