Description
Cesar Hernandez & Rafael Guimarães close out JakartaOne Livestream with their presentation
This migration case involved several challenges such as the fifth-largest population and largest territory in the world; complexity; and diversity, both geographic and economic. This session’s speakers discuss how they used MicroProfile projects such as Health Check, JWT Authentication, Metrics, OpenAPI, Rest Client, and Config to contribute to the success of the project; what benefits they saw; the challenges they faced; and how they solved them.

A
We
know
cesar
very,
very
well
from
tommy
tribe,
so
this
is
the
last
session
of
the
day
and
a
great
application
of
a
micro
profile,
and
we
will
learn
how
the
micro
profile
is
keeping
brazil's
medical
industry
safe.
So
without
any
further
ado,
thanks
for
hanging
out
with
us-
and
I
will
hand
it
over
to
rafael
and
cesar.
B
C
C
C
C
Learning,
training,
specializations
and-
and
we
have
the
government
health
departments,
making,
control
regulation
policies,
sanitary
surveillance,
keep
keep
records
and
provide
some
lessons
licenses
and
those
systems
of
the
government
integrate
and
share
information
with
the
medicine
council
in
the
united
states.
I
think
the
the
you
guys
have
the
american
association
of
things
like
that
and
and
the
medicine
casual
has
counselors
and
inspectors.
C
A
C
C
C
So
considering
the
these
challenges,
what
could
be
done
to
facilitate
interaction
between
the
doctors,
the
council,
how
to
access
legacy
systems
that
data
of
governments,
departments
without
bureaucracy
to
check
licenses
records
and
information
integrity?
Is
the
data
safe,
monitored,
fast,
reliable?
C
C
The
main
the
main
applications
today
is
support,
inspectors
and
counselors
in
their
principal
job,
that
is
professional
discipline,
guiding
inspections
and
and
and
to
serve
and
put
online
services
that
control
the
doctors
and
services
providers
in
their
life
cycle
within
concepts.
So
when
some
of
us
became
a
doctor,
we
died
as
a
doctor,
so
at
the
the
first,
the
when
we
start
to
study
medicine
at
the
end
of
our
life,
we
have
things
to
do.
D
C
C
We
have
three
major
three
main
modules:
inspections,
controlling
scheduling,
spectrums
executions,
checklists
images,
notification,
dynamic
forms,
reports
and
statistics.
Inspector
goes
to
the
hospital
takes
pictures
feels
some
checklist
and
transmit
to
this
the
main
server
and
then
there
they
they
make
the
their
decisions.
A
C
C
C
B
Thank
you.
So,
as
you
can
see,
you
know
it's
it's
a
complex
system
with
more
than
10
years
of
since
it
was
started
to
be
developed.
You
know,
as
with
any
you
know,
living
systems,
this
roblox
has
been
evolving
and-
and
one
of
the
first
thing
that
we
started
to
to
work
with
raphael's
team
at
the
beginning
of
the
year
was
to
be
prepared
for
the
namespain
space
change.
You
know
at
some
point
for
those
who
have
been
following.
B
What's
going
on
in
the
mailing
list,
the
conversations
you
know
that
we
had
the
the
decision
of
making
the
incremental
or
the
big
bang
approach
that
started
since
early
on.
So
around
that
time
there
was
the
need
to
start
planning
what
what
this
migration
that
is
happening
right
now
to
the
cloud
as
as
as
raphael
has
mentioned
over
the
past
two
years,
also
now
need
to
involve
the
the
namespace
as
part
of
the
key
points
to
change
so
for
for
for
all
of
those
that
are
just
joining
this.
B
B
E
B
We
I'd
like
to
present
this
slide
to
to
show
that
jakarta
is
one
of
many
other
projects
and
all
the
the
industries
that
are
involved
and
the
amount
of
contributors
and
commuters
that
the
entire
cliff
foundation
has
and
also
another
another
important
part
that
that
I
like
to
highlight,
because
it
is,
I
am
anticipating
questions
that
I
usually
get
when
we
are
talking
about
microprofile,
jakarta
e.
What
is
the
relationship
right
so
starting
from
the
point
that
eclipse
foundation
is
where
this
boat
is,
where
both
projects
are
hosted?
B
Actually,
the
top-level
project
is
ee4j
for
jakarta
eu.
So
this
is
their
relationship
in
terms
of
where,
where
the
products
are
hosted
there,
when
I
invite
you,
you
haven't
seen
the
the
previous
sessions,
I
invited
you
to
jump
to
to
the
previous
sessions,
because
there
were
many
questions
related
to
this,
how
how
jakarta
is
related
to
microprofile
and
so
on.
We
are
not
going
to
repeat
again
everything,
but
it's
just
a
way
to
easily
see
that
there
is
a
relationship,
and
I
like
to
see
this
as
a
synergy
from
both
projects.
B
A
little
bit
of
a
quick
microprofile,
we
have
seen
demos
like
coding
demos.
During
the
day
we
have
seen
a
little
bit
of
roadmap.
What's
going
next,
emily
replies
some
questions
about
that
again.
If
this
is
the
first
time
you
are
seeing
about
micro
profile
macro
file,
is
an
open
source
community
specification,
the
worst
having
java
micro
services
ready
in
in
the
modern,
as
we
call
our
native
environment.
B
Let
me
go
here:
you
can
find
more
information
and
join
the
project
by
going
into
microfile,
I
o
and
it's
implemented
by
different
vendors.
The
preg
itself
generates
specs
apis
and
tck.
It
doesn't
generate
reference
implementation,
like
we
used
to
hear
back
in
java
ee
and
then
when
you,
when
we
are
talking
about
jakarta,
e2
and
just
an
overview
in
terms
of
the
specifications
that
microprofile
has.
I
always
have.
B
I
always
add
these
from
from
the
official
slides
that
you
can
find
in
the
micro
file
website
and
people
also
start
asking
cesar.
Why
I'm
seeing
cdi
jsonp
jackson,
racing
jsonp
and
the
reason
for
that
is
that
those
are
the
baselines
or
to
the
the
baseline
for
the
building
blocks
that
allow
the
apis
of
microfile
to
work
and
and
integrate
solutions
on
a
cloud
native
environment
for
microservices.
B
So
you
already
saw
a
couple
of
demos
during
the
date
about
metrics
held
open
tracing
and
fault
tolerance,
so
each
each
of
these
specifications
could
require
a
45
minute
session
by
its
own.
So
the
the
takeaway
is
that
when
we
were
trying
to
understand
how
or
how
the
seals,
the
the
system
that
raphael
was
describing
was
built
and
what
will
be
the
next
step.
B
So
for
the
demo
we
are
gonna,
we
are
going
to
see
we're
gonna
use,
apache
tomy,
as
rafael
mentioned
pachitomi,
is
part
of
a
roam
up
of
this
migration
and
modernization,
and
I
like
to
present
apache
tommy,
like
apache,
for
all
of
those
that
are
familiar
with
apache
template
already
think
of
apache
tomy,
like
the
sum
of
apache
tomcat
plus
java
e.
I
left
java
e
on
purpose.
So
remember
now,
java
is
jakarta
and
it's
main
build
from
apache
components.
B
It's
an
open
source
project,
it's
micro
micro
profile,
compliant
as
david
mentioned
early
in
the
morning.
The
the
break
is
really
close
to
be
jakarta,
yeah,
I'm
sorry,
jakarta,
e9
compatible
and,
and
we
already
have
the
tomi
milestone
three.
I
have
a
typo
here,
ready
for
you
to
test
out
the
latest
and
greatest
of
of
this
of
this
package
migration.
As
is
stated
there
more
information
about
the
project
itself,
tomi.apache.org.
B
In
this
case,
for
for
when
we
were
analyzing
the
blueprints
of
the
new
version
of
the
system,
we
did.
We
put
the
choice
for
for
for
an
api
gateway.
In
this
case,
in
production
we
have
been
using
traditional
api
gateway,
which
is
one
of
the
products
that
tommy
drive
offers,
and
this
is
part
of
the
main
architecture
and
now,
in
terms
of
many
of
you
that
are
watching,
decisions
are
wondering:
okay,
it's
fine.
B
We
are
going
to
eat,
cake,
absolutization
and
and-
and
there
was
also
denounced
that
jakarta
e9
is
is
now
available.
You
know,
and
and
application
servers
did
the
migration
and
all
that-
and
you
know,
but
from
my
point
of
view-
and
in
this
case
I
will
say
gvr-
point
of
view-
the
project
itself
that
we
are
describing
with
raphael.
We
need
to
also
take
the
decision.
B
B
But
here
I
want
to
show
you
from
from
the
user's
point
of
view:
what
are
the
options
that
you
currently
have
right
now
to
start
testing
this
migration?
So
the
first
approach
obviously
is
to
say:
okay,
I
have
my
code
base.
In
this
case,
I
will
call
the
code
base
the
branch
that
actually
generates
your
jakarta,
ee8
and
microprofile3.x
or
independently
the
version
you
are
using
the
binaries
that
we
have
been
using
so
far
right
under
java
8.
B
and
then
yes,
kevin
has
pointed
out
that
microfiles
is
still
based
on
jakarta,
e8
and
javascript.
That's
why
I
put
a
question
mark.
Thank
you
for
the
clarification.
I
will
left
the
the
four
instead
of
the
four
and
x,
so
maybe
it's
gonna
be
five,
but
that
you
know
that
is
an
ongoing
discussion
right
and
so
the
approach
that
you
have
is
to
create
a
a
new
branch
and
then
that
branch
will
become
mastery
independently.
B
B
I'm
gonna,
I'm
gonna,
make
I'm
gonna.
I'm
gonna
provide
examples
for
for
for
gvr
and
for
the
system
we
are
describing.
You
already
start
seeing
some
kind
of
issues
right.
The
system
as
rafael
indicated,
needs
to
be
deployed
in
different
cloud
vendors
and
sometimes
if
the
system
is
going
to
be
deployed
by
and
any
other,
you
know
any
any
any
other
application
server
or
any
other
cloud
provider.
B
B
Okay,
no,
it's
not
a
question.
Okay,
but
okay.
Thank
you,
amelia
for
for
for
the
context
there.
So
what
I'm
gonna
show
you
right
now
is
how
this
this
second
approach,
you
know,
doing
a
grip
and
showing
the
result
of
the
grip
is,
is
it
is
is?
Is
it
isn't
so
much
fun?
You
know
the
possibility
of
something
goes
wrong.
Is
it's
almost
impossible,
so
we
we
like
to
see
demos
that
at
some
point
may
fail
right
to
see
if
he's
alive
so.
D
B
B
B
Okay,
thank
you
david.
I
think
I
have
a
typewritten
download.
Okay,
thank
you.
I'm
gonna
check
that
I'm
taking
note
here,
that's
good!
You
are
paying
attention
guys.
That's
that's,
really,
really
really
good!
Okay,
so
we
are
boot
insert
we
are
booting
the
server
right
now.
If
we
go
back
to
the
slide
that
that
was
the
step,
the
easiest
one
build
and
run
okay.
B
You
have
more
than
100
examples
of
jakarta
ee9
available
for
you
in
the
within
the
tomi
project
and
what
we're
going
to
do
is
to
download
but
notice
that
ion
purpose
left
the
examples
on
the
8th
version
right
and
at
this
point
I
already
did
this-
I
download
the
entire
the
entire
project
with
all
the
samples
I
already
unzipped
that
and
what
I'm
gonna
do.
Is
I'm
gonna
really
quickly
go
into
the
microprofile
custom?
Health
check
example
that
we
have
here
again.
B
This
is
java
8,
and
I
already
have
it
here
open
on
my
ide,
and
the
take
away
from
these
before
going
into
the
code
and
see
what's
going
on
inside.
Is
that
the
only
extra
thing
that
you
will
have
to
add
to
your
existing
system
that
you
want
to
test
in
a
jakarta
environment
is
that
we
are
using
here,
the
eclipse
transformer
transformer
plugin
that
was
described
in
the
previous
session.
B
Once
we
make
a
request
to
see
how
is
the
weather
of
the
day,
no
further
requests
are
going
to
be
allowed.
So
therefore,
the
custom
health
check
is
going
to
say:
okay,
something
goes
wrong,
and
now
the
server
is
down
as
simple
as
that.
So
what
we
are
going
to
do
now
now
that
you
double
check
again
within
ports
that
we
are
using
javax
namespace
we
are
going
to.
B
B
Please
kids,
don't
do
this
at
home,
don't
skip
test,
but
for
the
sake
of
speeding
up
the
demo,
so
we
don't,
we
don't
run
out
of
time.
We
still
have
plenty
of
content.
I'm
gonna
just
build
and
see
the
actual
binaries
there.
Let
me
see
what
else
whatever
else?
Okay,
so
yeah!
This
is
straightforward!
Raphael!
You
have
the
portuguese
version
here
available.
If
you
want
to
to
double
check
the
the
the
documentation
we
have,
the
english
and
the
spanish
version.
B
There
is
an
ongoing
migration
translation
effort
within
the
tummy
project
for
for
all
of
these
concepts,
and
yes,
okay.
So
now
now
we
have
here
the
binaries,
something
that
I
want
to
highlight.
So
you
can
double
check
that
the
plugin
is
doing.
Something
is
that
you
will
see
here
the
transformer
plugin
doing
his
magic.
B
This
is
the
one
that
we
are
gonna
be
deploying
into
tommy.
We
are
ready
to
play
it
in
the
slides.
You
will
see
that
we
have.
You
know
the
the
copy
to
from
from
one
place
to
another
one,
but
the
important
part
here
is
how
we
can
inspect
that
the
bike
change
already
happens
so
for
that
I'm
gonna
with
the
magic
of
notative
login,
but
the
magic
of
the
copy
and
paste
here,
I'm
gonna
actually
open.
A
B
B
Everything
else
was
left
there,
because
our
microprofile
health
check,
all
those
annotations,
are
still
microprofile
related
imports
and
if
we
inspect
also
the
input,
you
will
see
that
the
the
rest
endpoints
also
were
migrated
at
bytecode
level.
So
in
this,
in
this
case
we
are
validating
that
the
bytecode
is.
It
was
already
migrated
for
you.
B
I
am
double
checking
now
the
health
of
the
servers
I
previously
deployed.
I
didn't
copy
the
war
file,
but
it's
already
deployed
so
it
the
custom
health
check
is
actually
you
know
warning
us
that
we
just
have
one
more
ticket
to
go
in
terms
of
the
of
the
usage
of
this
api
oops
here.
So
we
have.
Okay.
Today
is
a
sunny
day
for
all
of
those
that
are
1
am
in
the
morning.
B
I
don't
think
that's
the
case,
but
you
know
if
I
call
again
now
the
the
the
custom
health
check
you
will
see
that
the
weather
is
unavailable
and,
and
also,
if
I
call
now
the
overall
status
of
that
service,
we
we
did.
We
did
this
on
purpose
right
for,
for
demo
is
down.
So,
as
you
can
see
here,
this
is
how
you
can
easily
test
your
existing
jakarta,
e8
applications
and
also
tested
in
a
in
a
really
clever
way.
B
I
will
say:
against
a
jakarta
ee
server,
jakarta,
e9
server
and
leverage
the
the
migration
to
mike
to
to
the
eclipse
transformer
plugin.
The
slides
are
going
to
be
available
after
this
session.
If
you
want
to
take
a
look
more,
there
was
an
entire
session
for
just
the
clips
transformer,
but
this
is
an
approach
that
we
took
in
the
tummy
project,
along
with
the
with
other,
with
other
application
servers
about
how
to
how
to
quickly
boot
up
and
make
it
made
the
the
migration
of
your
applications.
B
B
I
will
say
two
years
ago
and
and
starting
to
incorporate
microfile
as
the
base
architecture
of
the
system
that
pays
pace
at
the
at
the
end,
and
I
will
say
at
the
end
of
the
first
iteration
that
was
at
the
beginning
of
this
year.
Did
we
we
made
this
session
before
coding,
19
and
rafael
is
going
to
show
us
what
are
the
benefits
that
we
have
found
in
this
last
12
months
of
interacting
with
this
architecture.
C
So
we
we
recently
at
march
at
beginning
at
covid
19
here
in
south
brazil,
the
the
people
cannot
go
to
the
doctor's
office,
so
the
telemet
scene
became
very
use
useful
to
to
to
doctors,
attend
people
and
to
and
to
make
their
medical
practice
and
doctors
make
prescription
and
make
some
notes
some
examinations
prescriptions
to
the
to
the
patients,
so
how
how
they
they
they're
gonna
make
this
their
job
without
the
physical
presence.
So
we
may
we
made
a
system
in
very
hurry.
C
C
Can
you
put
another
slide?
Here's
the
example
of
the
digital
prescription.
We
have
qr
code,
we
have
endpoint
two
valid
to
pharmacies,
validate
them
and
we
have
a
password
too,
and
we
have
here
an
example
of
use
of
cryptoconverter
that
that
we,
if
some
somebody
took
our
database,
they
don't
understand
nothing
inside.
B
We
have
a
question
about
how
micro
file
health
check
was
applied.
We
are
running,
we
only
have
four
four
minutes
and
we
have
for
each
of
the
specifications
the
before
and
after
and
what
was
the
overall
impact
and
a
little
bit
of
code
about
each
specification
again.
That
is.
This
is
one
hour
session
normally
so
in
in
the
case
of
of
health
check,
health,
health
checks
and
metrics.
B
B
I'm
sorry
I
was,
I
was
a
little
bit
on
it,
so
it's
think
that's
this
system
needs
to
be
deployed
in
different
cloud
providers
and
also
needs
to
be
needs
to
be
able
to
report
to
that
particular
infrastructure
on
that
state.
The
amount
of
information
that
is
needed
today
to
understand
that
the
system
is
is
behaving
well
so
before
the
integration
you
know
of
the
applying
the
health
checks
and
microfilemetrics
there
was.
B
This
process
was
really
manual,
it
didn't
have
a
lot
of
coverage
and-
and-
and
you
know
it
requires
the
the
common
question
of
we
don't
know
what
happened.
We
need
just
to
restart
the
server
and
and
and
and
hope
that
everything
is
fine.
You
know,
and
this
ended
up
being
a
reactive
approach,
most
most
of
the
time
and
after
applying
health
checks
and
metrics.
B
Now
there
is
a
json
based
standard
amount
of
alerts
and
metrics
that
we
offer
to
to
to
each
state
that
decide
of
by
requirement
installed
on
premise
or
in
the
cloud
that
they
they
use.
There
was
also
the
implementation
of
a
user
of
a
ui
of
a
dashboard
based
on
that
the
system,
and
I
think
we
have
a
couple
of
examples
here.
This
is
something
that
previously
was.
B
I
don't
know
if
we
have
other
questions
carlos
says:
does
the
plugin
works
well
with
fully
classified
domains?
Names
without
imports,
I
mean
to
say
fully
qualifying
names
in
the
classes.
That's
a
good
questions
carlos
I
haven't
tested
that
yet
I
will
say
yes,
I
will
have
the
risk
to
say.
Yes,
if
people
from
the
front
from
deploying
is
still
on
the
chat,
they
can
help
us
to
reply.
I
will
say:
yes,
we
can
make
a
test
we
are,
we
are.
B
B
That's
yes,
that's
a
quick
question
too.
Let
me
see
if
we
included
that
with
judge
authentication
risk
client
open
api.
We
have
examples.
We
don't
have
example
of
all
tolerance
but
yeah.
Basically,
you
know
the
time
in
terms
of
alternatives.
The
timing
is
really
important
right,
raphael
we
are
now
in
providing
like
a
we
are.
We
are
becoming
a
hub
of
integrating
as
rafael
was
describing.
You
know,
pharmacies,
providers
and
and
doctor
offices,
so
you
know
having
the
ability
to
know.
B
C
B
B
B
C
B
The
system
yeah
allow
the
system
to
integrate
with
some
things
that
we
were
not
even
imagined
that
we
were
need
to
be
integrated
now
the
system
is
used
also
to
provide
to
me
to
to
doctors,
access
to
medi-line
and
and
and
other
databases
of
information
that
are
constantly
being
updated
and
because
the
system
now
is
a
like
a
helpful
for
login
doctors
and
pharmacies
and
everything
all
those
systems
are
now
being
authenticated
against
our
system
and
microprofile.
All
out
with
json
web
tokens
is
is,
is
is
what
allowed
us
to
integrate.
