From YouTube: The Level Up Hour (E23): APIs and their Gateways
Description
What's an API Gateway? Do I need one? From gateways like 3scale to conferences like GlueCon, APIs seem to be all the thing. However, what does this even mean? Like, an API is "just" an Application Programming Interface, why all the buzz? Join us to demystify the API-buzz which, while technically accurate, is really a euphemism for services.

All
right
live
good
morning,
good
afternoon
good
evening,
wherever
you're
healing
from
welcome
to
another
edition
of
the
level
up
hour.
Episode
of
the
level
of
power,
I
should
say
I
am
chris
short
executive
producer
of
openshift
tv,
I'm
joined
by
the
illustrious
langdon
white
landon.
How
you
doing
today,
not.
B
B
A
B
Virtual
issue,
yes,
is
virtual,
and
let's
see
where
did
my
super
window
go
here?
It
is
so
it
is
virtual.
This
year
it
is
the
18th
through
20th,
which
is
the
end
of
next
week.
I
am
actually
going
to
be
giving
a
talk
about
service,
mesh
and
event,
driven,
architectures
and
stuff,
as
well
as
giving
or
kind
of
highlighting
some
research
in
a
keynote
about
application.
B
Architectures,
so
you
know
those
might
be
fun,
it
is
free
as
always,
and
because
it's
virtual
you
can
go,
it
is
the
the
time
is
kind
of
set
up
so
that
at
least
north
at
least
you
know
kind
of
the
americas.
You
know
north
south
and
europe
kind
of
north-south
should
have
the
timing.
Work
pretty
well,
you
know
so.
B
Apac
is
always
tough
to
to
also
include,
but
there
should
be
some
overlap,
so
there
should
be
stuff
that
is,
and
you
know
and
other
stuff
that
is
gonna-
be
harder
to
get
to
depending
on
time
zone
you're
in
the
other
thing
I
kind
of
wanted
to
mention
too,
was
you
so
definitely
check
that
out?
Go
register?
B
Yeah,
it's
all
open
source
software,
it's
all
and
I'll,
accept
the
cookies
and
and
and
not
product
right.
So
it's
it's
all
the
actual
upstream
project.
So
it
can
be
very
illuminating
and
I
don't
know
anybody
who
who's
been,
who
doesn't
enjoy
it,
so
I
highly
recommend
it.
So
that
was
the
first
thing.
B
Like
we're
going
to
have
dan
walsh
and
chris
wright
and
brent
bowdy,
all
talking
about
various
topics
in
the
near
future,
so
keep
an
eye
on
the
streaming
calendar.
If
you
would
like
to
see
them,
we
are
slowly
updating
the
kind
of
the
abstracts
and
the
events
and
that
kind
of
stuff,
but
we
have
them
confirmed
as
speakers,
and
we
have
a
few
others
in
the
in
the
offing
as
well
that
we're
hoping
to
get
on
the
show.
I.
A
B
B
B
Exactly
so,
this
is
the
level
up
hour
where
we
talk
about
containers
and
why
they're
useful
in
your
kind
of
everyday
life
and
random
to
some
extent
other
topics
that
are
either
suggested
by
by
by
audience
members
or
kind
of
things
I
overhear
in
other
shows,
or
things
like
that,
and
and
actually
so
somebody
commented
in
the
chat.
The
chat,
mr
container
dan,
actually
we're
gonna
specifically.
B
A
B
And
I
just
think
the
way
he
explains
stuff
is
is
very
clear.
At
least
you
know,
I
find
him
very
under
like
very
understandable
on
hard
topics
and
so
yeah,
so
I'm
really
hoping
he
can
come
and
talk
to
us
about
kind
of
how
security
and
se
linux,
which
is
kind
of
like
a
a
subset
of
security
and
containers,
work
and
hopefully
explain
some
of
that
in
ways
that
people
can
get
a
better
understanding
of
how
all
that
stuff
goes.
A
A
A
A
B
B
Yeah,
the
other
challenge
I
have
is
my
my
desk
is
actually
quite
high
up.
It's
not
like
quite
high
enough
to
be
like
a
standing
desk,
but
it's
it's
higher
than
standard.
So
I
also
couldn't
use
like
a
regular
chair,
but
yeah.
It's
it's
actually
worked
out
pretty.
Well,
I
I've
enjoyed
it
yes
and
to
detective
conan
kudo,
yes,
not
in
trotto.
I
am
not
in
toronto.
B
Lot
of
conferences
and
stuff,
you
know
we
always
are
curious.
How
they're
gonna
run
the
venue
and
how
are
they?
Gonna
run
the
booths,
and
you
know
all
the
other
stuff,
because
you
know
like
you
see
different
ones.
You
know
like
what
kind
of
swag
are
they
doing?
You
know,
and
you
know
you
kind
of
want
to
you
know,
steal
the
best
ideas
you
can
get
right
exactly
and
now
we're
all
like
hyper
focused
on
the
virtual
conference
platforms
like.
Are
they
running
it
with
a
separate
chat?
A
B
A
A
B
B
B
B
B
B
B
For
openshift
and
I'm
trying
to
put
either
this
show
like
the
next
episode
or
the
episode
after
that
of
this
show
together
about
it
or
we're
gonna,
do
a
special
edition
show
so
that
we
can
actually
address
those
on
the
show
itself,
because
they're
com,
like
the
answers,
aren't
something
I
really
like.
I
could
have
written
like
walls
of
text
to
try
to
get.
A
B
B
A
A
A
A
A
B
B
B
B
And
so
doing
things
at
a
smaller
scale.
So
if
if
we,
if
I
had
gotten
a
little
further
along
on
the
cool
store
work,
I
think
that
actually
might
be
a
good
model
for
it
right.
But
I
thought
we'd
kind
of
talk
about
it,
a
little
bit
in
the
abstract
and
then-
and
I
could
show
some
some
examples
rather
than
demos
per
se
cool
and
then
we
could,
you
know
then
maybe
we'll
revisit
it
when
we
can
bring
in
the
cool
store
and
and
kind
of
demonstrate,
their
api
gateway.
B
A
B
B
A
B
Yeah,
so
I
was
kind
of
like
maybe
I
should
know
what
they
have
to
say
before
I
go
and
say:
api
gateways
bomb,
so
long
story
short.
You
know
it
was
kind
of
funny
as
as
is
often
the
case
when
I
am
trying
to
explain
stuff
in
technology
weirdly
enough,
I
find
the
wikipedia
definitions
of
them
shockingly
good
and
shockingly
easy
to
understand.
B
B
B
So
in
those
days
we
when
we
were
doing
the
soa
idea,
so
the
soa
service
oriented
architectures,
were
basically
a
top-down
approach
to
integrate
all
the
services
together
of
your
environment,
so
that
you
could
deliver
on
applications
and
the
first
up.
The
top-down
approach
was
problematic.
As
in
when
you
tried
to
do
a
directive
from
like
this
cto's
office,
it
didn't
take
with
your
developer
on
the
ground.
B
B
The
problem
is
getting
a
revision
to
one
was
like
a
matter
of
years
and
during
that
same
time,
frame
is
when
we
saw
the
same
thing
that
the
guy
from
redmonk,
who
I
just
blanked
on
his
name
but
who
wrote
the
you
know
the
developer
is
king.
Whatever
that
book
is
called
now
now,
I'm
all
totally
blanking.
B
So,
but
during
that
period
right
so
when
when
that
swing
was
happening
in
this
in
the
monolithic
power
structure
that
was
like
soa
and
that
kind
of
stuff
you
had
these
service
meshes,
they
were
all
very
complex.
You
had
things
like
you
know,
kind
of
esbs,
which
was
the
enterprise
service
bus.
You
had
you,
you
know
largely.
This
is
also
where,
like
java
application
servers
really
got
out
of
hand,
and
you
had
java
beans
and
all
that
stuff.
B
B
B
B
But
was
this
idea
of
all
these
different
services
kind
of
becoming
available
and
being
able
to
be
used
largely
led
by
or
kind
of,
I
don't
want
to
say
inspired.
It
was
happening
all
over
the
place,
but
starting
to
be
realized
by
a
famous
memo
that
bezos
wrote
at
amazon
about
the
what
they
call
the
two
pizza
team.
B
Right
right,
so
what
happened,
though,
was
exactly
that
is
that
okay,
now
we've
got
this
whole
mess
of
services.
How
do
we
manage
them
right
because
excuse
me,
so
how
do
we?
How
do
we
manage
them
as
both
kind
of
internally
but
then
also
externally
right,
because
we
might
want
to
have
external
people
be
able
to
call
them,
and
this
is
where
the
concept
of
api
management
or
api
gateways
started
to
land.
B
B
Gonna
go
well,
so
instead
you
do
things
like
a
gateway.
You
know,
platform
of
some
kind,
and
so
companies
started
to
make
a
product
or
products
right
that
just
delivered
that
gateway
aspect.
Another
one
that
started
to
show
up
was
the
publishing
problem.
Okay.
So
how
do
you
do
the
simple
publishing
problem
which
is
like
make
other
parts
of
your
organization
or
other
organizations,
aware
of
the
fact
that
you
have
this
api
right,
but
then
almost
more
importantly,
is
how
do
you
make
them
aware
of
revisions
to
the
api?
B
And
so
you
know,
new
version
has
come
out.
How
do
you?
How
do
you
share
that
information
at
a
technical
level
and
then
kind
of
the
next
level
down
or
the
next
next
thing
down
on
on
this
list
right,
it's
kind
of
developer
portal,
which
is
like
okay,
so
the
publishing
tools
are
about.
How
do
you
make
the
like
software
aware
of
api
change,
but
then
how
do
you
make
the
humans
who
are
going
to
consume?
B
B
Developers.Companyname.Com
and
you
will
often
get
a
solid
bleed
on
sorry.
It's
got
a.
I
was
just
looking
at
a
message.
Yes,
it's
yeah!
So
when
you
you
know,
so
you
can
get
a
solid
lead
on
on.
What's
going
on
in
those
you
know
in
that
particular
environment,
and
so
we
have
then
you
kind
of
get
further
on
right.
So
now
you
want
to
know
about
what's
actually
going
on
in
the
environment,
so
you
get
reporting
and
analytics.
Oh
and
then,
finally,
you
want
to
make
money
on
it.
B
Okay,
now
making
money
on
it
could
be.
There's
this
old
thing.
I
don't
even
know
if
they
still
do
it,
even
though
we're
part
of
ibm,
but
they
there
used
to
be
this
thing
called
ibm
blue
dollars,
which
is
dollars
that
ibm
would
spend
amongst
itself
so
that
you
can
track
that
this
part
of
the
organization
was
buying
from
that
part
of
the
organization
without
spending
real
money
right.
But
you
you
know,
as
a
you
know,
as
the
organization
that's
running
the
weblogic
team
or
sorry,
that's
not
ibm,
that's
or
let's
say
websphere.
B
You
want
to
say.
Okay,
I
want
to
go
as
let's
say:
red
hat
is
buying
a
bunch
of
websphere,
even
though
we
have
jboss
right
but,
let's
just
say,
we're
buying
a
bunch
of
websphere.
The
websphere
team
wants
to
be
able
to
take
credit
for
the
sale
right,
so
you
have
these
these
blue
dollars.
They
used
to
call
them.
So
that's
where
you
want
the
monetization
is
to
kind
of
track.
B
What's
happening,
you
know
within
the
organization,
but
it
could
be
external
monetization
as
well
right,
so
you
want
to
you,
know,
buy
whatever
from
whoever
and
so
one
one
of
the
kind
of
weird
little
things
I
wanted
to
kind
of
show.
You
is
that,
and
I
was
kind
of
getting
at
this
a
little
bit
is
this
concept
is
not
like
all
that
different
than
the
service
management
concept
right.
A
B
Again,
hopefully,
you
can
see
that
my
picture
big
enough,
but
if
you
notice
here
we
have
you
know
api
management
in
the
same
bucket
right
as
like
soa
management
produced
by
the
same
company.
That's
weird!
What
if
you
know
like?
Are
they
different
like?
Are
they
the
same,
and
I
would
argue
that
largely
it's
the
same
concept,
it's
this
problem
of.
As
soon
as
you
have
a
set
of
services,
it
doesn't
really
matter
like
once
they're
kind
of
over
a
certain
size.
B
They
can
be
micro,
they
can
be
macro,
they
can
be
coming
from
third
parties
that
can
be
coming
from
wherever
you
need
to
start
to
understand.
What's
going
on
so
yeah,
that's
kind
of
the
that's
kind
of
largely
the
point
of
the
api
management
api
gateways,
and
then
we
start
to
get
into
sorry
technology.
Defeating
me,
I'm
going
to
share
again
and
share
trying.
B
B
B
B
But
you
know
this
is
a
api
tool
chain
that
came
up
in
the
show
last
time
because
we
were
talking
about
the
cool
store,
but
it
gets
both
cooler
and
more
boring
than
that,
because
we
can
talk
about
things
like,
as
I'm
sure,
oops
wrong
button.
Most
people
are
familiar
with,
although
I
think
I
think
I
forgot
to
log
in.
B
A
B
B
A
A
B
B
A
B
Kind
of
thought
we
would
get
to
their
like
website,
but
I
guess
I
don't
even
know
if
they
have
one,
but
they
kind
of
do
the
same
thing
right.
It's
like
you
know
on
this.
That's
not
a
great
example,
but
you
know
kind
of
yeah.
Here
we
go
so
on
this
kind
of
event.
Do
this
other
thing
over
here,
so
they
are
all
over
the
place.
B
A
B
Could
be
interesting
right
right,
so
so
there's
I
mean
there's
a
ton
of
good
stuff
here
and
then
we
also
even
have
you
know,
conferences
dedicated
to
this
concept
and
this
one
I
particularly
like
just
because
I
think
the
name
is
hilarious,
but
I'm
not
sure
what
they're
doing
for
21..
They
seem
to
be
doing
something
in
person
in
may,
which
I'm
like.
B
Yes,
yeah,
so
it's
in
this
big
huge
conference
building,
but
I
went
once
maybe
twice
and
it
was
a
great
little
conference.
You
know
you
and
like
three
or
four
thousand
of
your
closest
friends
and
but
the
point
being
is
just
that
this
is
all
like
the
entire
conference
is
about
like
how
do
I
work
with
the
apis?
I
need
to
manage
or
the
apis
that
I
want
to
consume
so
that
I
can
turn
them
into
something
else,
etc,
etc.
So,
api
management.
B
So
that's
kind
of
what
I
wanted
to
get
to
and
you
know
and
like
I
said
you
know
we
do
and
actually
I
really
like
three
scales
kind
of
what
is
an
api
gateway
thing
here,
too,
okay,
and
so
like.
I
just
thought
these
blurbs
were
well
written.
You
know
and
kind
of
made
sense
to
me,
but
really
what
I'm
getting
at
here
is
that
the
the
term
api
here
is
just
too
limiting.
B
A
A
B
What
you're
doing
is
you're
taking
services
connecting
together
and
creating
new
things
out
of
them
or
you're,
offering
them
to
be
created,
new
things
out
of
them,
and
so
what
I
think
you're
really
starting
to
see
is
that
you
know
there's,
there's
kind
of
open
source
versions.
Kind
of
like
the
three
scale
is
the
the
management
side,
whereas,
like
camel,
is
the
the
like
kind
of
backbone
side.
You
have
service
buses,
which
kind
of
deliver
messages
between
those
various
services.
B
A
B
Is
throughput
whereas
an
esp
is
is
perfection
you
know
so,
and
sometimes
you
need
different
ones
right
so
long
story
short.
Is
you
need
different
ways
to
you?
Want
you
need
all
these
different
services
to
be
able
to
communicate
with
each
other,
and
you
need
a
way
to
manage
them,
and
this
is
one
thing
that
really
like
soa
recognized
right
with
all
their
kind
of
high
level
kind
of
protocols
and
interfaces
and
specs
and
all
that
stuff
is.
B
It
was
really
really
focused
on
the
management
of
them
which
typical
in
the
software
world
right.
It
was
kind
of
ahead
of
its
time,
because
people
just
wanted
to
build
some
services
and
make
them
talk
to
each
other
right.
They
didn't
really
want
to
make.
They
didn't
want
to
worry
about.
You
know
whether
or
not
that
service
was
going
to
have
to
be
revised
right,
yeah.
A
B
B
B
Sorry-
and
I
could
not
think
of
this
last
night
when
I
was
putting
the
notes
together
wow,
but
the
point
is,
is
that
you
have
so
that's
a
an
application,
binary
interface
and
the
reason
I
almost
like
that
term.
Better
than
service
is
because
we
have
a
long
history
with
those
concepts
and
so,
for
example,
with
rel
rel
has
been
around
for
you.
B
B
Exactly
and
if
you
think
of
your
services
in
the
same
way
right
that
you're
going
to
have
to
revise
them,
that
you're
that
they
are
locked
up
and
that
you
need
to
have
a
mechanism
to
expand
them,
grow
them
change
them
whatever.
Without
breaking
all
your
clients,
you
will
have
a
much
better
day,
and
so
that's
why
I
don't
dislike
the
term.
B
B
B
B
B
B
Etc
and
then
noah
friction
still
still
solid
there
at
3
000
points
and
then
we
kind
of
have.
We
actually
had
a
few
different
people
at
the
400
point
level,
and
so
I
decided
to
feature
somebody
else.
This
is,
I
think
we
decided
this
was
mickello
yeah
and
you
know
so.
400
points
there
pretty
awesome
and
and
detective
conan
is
is
moving
on
up.
So
that's
awesome.
You
know
you
can
always
go
back
and
watch
old
episodes.
A
B
B
A
B
Fair
enough
right,
so
if
we
don't
do
that,
we
will
be
doing
something
else,
so
watch
the
twitters
and
I
will
be
posting
it
as
soon
as
it
is
confirmed
one
way
or
the
other.
I
was
basically
planning
on
giving
in
the
rest
of
the
day
today,
if
I
haven't
heard
back
today
I'll
make
the
call
to
push
that
out
to
later,
but
I
think
the
health
index
is
really
interesting,
and
so
I
really
like
that.
A
A
B
So
if
you
haven't
done
this
before,
you
can
go
and
collect
your
own
sweet,
sweet
internet
points
by
either
going
to
the
level
up
point
form
and
just
entering
the
code
or
the
deep
link
there
kind
of
basically
just
pre-populates
the
code
for
you
so
yeah.
It
just
makes
it
a
little
bit
easier.
A
little.
B
A
B
B
B
B
B
B
So
just
to
explain
it
a
little
bit
so
what's
gonna
happen
is
I'm
gonna
start
it
and
then
it's
gonna.
It's
gonna
show
you
a
question.
Then
it's
going
to
show
you
like
some
colors
for
answers,
but
the
colors
also
have
like
a
an
iconography
in
case
you're
color
blind.
So
you
can
pick
which
answers.
Not
all
of
the
answers
are
single
choice.
So
just
keep
that
in
mind
so
pay
attention
to
whether.
B
B
A
B
All
right,
we
don't
have
too
many
questions
here.
So,
okay,
the
following
are
elements
of
api
management,
and
so
I
showed
this
to
you
earlier.
Let's
see
how
much
you
were
paying
attention.
Okay,
I'm!
I
am
a
little.
I
will
say
I'm
a
little
disappointed
in
myself
in
my
quality
of
pictures,
but
you
know
it
they're.
Okay,
so
usually
I
try
for
much
more
terrible
photos
so
yeah,
so
the
gateway
itself
right
is
like
kind
of
how
you
keep
track
of
what
apis
there
are.
B
A
A
A
B
A
A
A
B
So
so
this
this
was
kind
of
funny
is
that
in
a
sense
both
are
correct.
But
technically
this
came
from
the
soa
management
interface
from
mulesoft.
So
because
that
was
kind
of
my
point
through
a
lot
of
the
episode
is
that
api
management,
service
management,
soa
management,
they're
really
all
the
same
thing,
and
you
know,
however,
because
branding
because
marketing,
because.
B
B
A
B
B
B
B
I
have
started
my
list
of
previous
episodes
and
what
we
talked
about
in
them
so
that
we
can
kind
of
like
I
I
want
to
like
be
able
to
have
them
off.
So
we
can
kind
of
say,
go
watch
episode,
blah
blah,
but
I
haven't
quite
finished
so
hopefully,
hopefully
by
next
time,
we'll
see
so
yeah
all
right,
cool
and
rushmede.
We
apologize
that
you're
winning
and
but
again
I
will
say
you
never
know
there
could
have
been
harder
questions
coming
up.
A
B
B
A
B
Think
of
with
api
management
right,
they
used
to
be
the
same
thing,
so
you
are
similar
at
least
so.
You
will
find
references
where
a
service
mesh,
a
service
mesh
sounds
more
like
an
api
gateway
but
they're
they're
kind
of
sorry,
I
like
the
soa
and
dutch,
so
you
will
find
references
where
service
mesh
is
kind
of
sounding
like
an
api
gateway,
but
they're
not
the
same
thing.
B
They
are
not
the
same
thing.
They
do
not
do
the
same
thing,
but
it
is
likely
that
if
you
have
a
significant
number
of
services,
particularly
if
you're
exposing
them
to
the
outside
world
for
consumption,
you
will
need
both
or
or
need.
You
will
want
both
yeah,
potentially
yeah
yeah.
Almost
actually,
I
would
say
if
it's,
if
it's
for
reals,
you
know
if
it's
production,
if
you
have
a
you,
know
a
not
insignificant
number
of
them.
I
think
you
want
both
almost
always.
A
A
A
A
B
B
A
B
A
Yeah,
I
think
I
think
we're
good
next
up
on
the
show.
Today

the
one
