Concepts
All
of
the
code,
libraries,
and,
data
that
are
needed
in
my
code
order
to
run
my
code
on
a
system
supplied
stack
Instances
make
my
applica;on
scale.
The
more
instances
the
more
load
the
app
can
handle
My
app
is
URL
addressable
and
can
have
mul;ple
URLs,
http://www.foo
some
clouds
allow
custom
domains
Services
are
used
to
extend
an
applica;on
with
higher
level
func;ons
like
a
KV
store
or
email
gateway
