What do you mean
by ‘serverless’?

27.
“Serverless”

28.
Gojko Adzic
It is serverless the same way
WiFi is wireless.

29.
Serverless means…
don’t pay for it if no-one uses it
don’t need to worry about scaling
don’t need to provision and manage servers

Serverless will fundamentally change
how we build business around
technology and how you code.

37.
Why serverless?

38.
more Scalable
(and scales faster!)

39.
Cheaper
(don’t pay for idle servers)

40.
Resilience
(built-in redundancy and multi-AZ)

41.
Secure

“DATABASE LOCK-IN IS THE ROOT OF ALL EVIL”

91.
ORM

92.
a load of unnecessary
complexity that didn’t end up
making DB migrations any
easier, and forced you to the
least common denominator of
feature sets and stop you from
taking advantage of your DB in
the first place…

93.
nooooooooooo, wish I hadn’t used an ORM!!

94.
The true danger with lock-in, especially with serverless, is the potential
for data lock-in. Data has gravity. It accumulates. Data is economically
disincentivized to leave, by way of platform pricing. This is the single
biggest threat to vendor choice.

95.
is vendor lock-in a risk?
YES

96.
is the return worth the risk?
ABSOLUTELY!

97.
there are no silver bullets

98.
understand the trade-offs
