Cloud
Services


AWS
Auto
Scaling

•  Automa:cally
adds
or
removes
EC2
instances

•  Based
on
low/high
threshold

–  CloudWatch
metrics
(EC2,
RDS,
SQS/SNS,

…)

–  own
custom

•  Scheduled

•  Fixed

Simple

Service
(SQS)

•  Similar
to

•  Zero
installa:on,
oﬀ-‐instance,
WS-‐API

•  1

•  At

•  Message

-‐>
No

Simple
No:ﬁca:on
Service
(SNS)

•  Similar
to
JMS
topics

•  1

communica:on

•  best-‐eﬀort
seman:cs

•  Supports
following
messaging
formats

–  HTTP(S)
using
POST

–  Email

–  Email
with
JSON
format

–  SQS


SQS
vs.
WebLogic
JMS
Queues


SNS/SQS
or
JMS?

SQS/SNS
:

•  Similar
in
func:on

•  Zero
installa:on,
but
AWS
only

•  Less
parameters
(ACK

compr.,
ﬂow

•  No

•  Unlimited,

•  Backup

•  Minor

•  No

RDS
or
Custom
AMI?

RDS
is
the
be^er
solu:on
if

•  You
need
a
DB
quickly

•  You
don’t
have
much
DB
or
cloud
knowledge

•  You
don’t
want
to
hire
an
DBA

•  What
you
care
is
the
JDBC-‐URL
to
connect

Calculate
the
monthly/yearly
costs!

conclusion


Conclusion

•  OFM
is
ready
for
the
cloud

•  There
is
a
learning
curve
involved

•  Cloud
services
cannot
replace
clustering
/
HA

setup
for
JMS
for
Oracle
products
(OSB
etc.)

•  Oracle’s
public
cloud
oﬀering
can
be
improved

•  Clouds
are
there.
You
can
start
today!
