Monolithic Applications
Single monolithic Application.
Single large deployment.
One Database for entire app.
Organized around technology layer.
State in each runtime instance.
One technology stack for whole
app.
In process call locally-SOAP.
Microservices
Multiple small minimal service function .
Independent deployment of each.
Each service has separate data store.
Organized around business capabilities.
State is externalized.
Choice of technology for each microservice.
REST calls over HTTP, Messaging or Binary.

13. 13
An open highly available
docker container based
elastic polyglot cloud
platform.

14. 14
• Application run on
Oracle Linux in docker
container.
• Stateless application
- Ephemeral disk.
- Storage through
database or storage service.

15. 15
• On demand elastic scaling
either through service
console or using service
REST API.
• Scale Out/IN
- add / remove ap p lication
instances to h andle workloads.
• Scale up/ down
- a dd / remove RAM to
accommodate ap p lication memor y
requirements.

16. 16
• Java application can use Java
Flight Recorder to monitor
applications and JVM
behavior analyze in Mission
Control.
• Use application Per formance
monitoring cloud ser vice for
advanced use case.

17. 17
• New Java and Node releases
published in the ser vice
console.
• One click upgrade to latest
releases-applications are
simply restar ted to upgrade
to new run time.

19. 19
• Comes with pre-built runtimes for key
programming languages and platforms, and it is
expected for the stack to support others any
time soon.
• For maintainability it provides Java SE advanced
features such as Flight Recorder, Mission Control,
memory management and security updates.
• Web-based user interface and REST API.
• Open platform that supports all Java frameworks
and containers such as Spring, Play, Tomcat, and
Jersey.
• Enterprise-grade support from Oracle.
• Store and retrieve data, Oracle Cloud
Infrastructure Object Storage Classic is best fit.
• Communication, supports via Oracle Messaging
Cloud Service. Your application communicates
with that service via its REST API, so no special
security configuration is necessary.

20. 20
• Information using
Ser vice Console.
Indication regarding
application health
can be retrieved
directly within
Oracle ACC ser vice
console.
• After-opening
ser vice console, one
must access ser vice
for each application
instance to check avg
memor y usage for
each instance

21. 21
• O ne console to manage
log v ia O racle Storage
cloud and
administration tasks.
Recording tab
generates detailed
recordings of th e Java
Vir tual Mach ine ( JVM)
and th e ap p lication it
is running.
• Th e recorded data
includes an execution
p rofile, garbage
collection statistics,
op timization decisions,
ob ject allocation, h eap
statistics, and latency
events for locks and
I/O. O racle
Management Cloud can
also b e integrated .

22. 22
• Use th is feature to
connect with Oracle
database cloud or
MyS Q L Cloud S er v ice.
You can also add
env ironment var iab le
at run time. It will
also disp lay
dep loyment h istor y.

23. 23
• Can manage multip le
instances with out of
b ox load balancing. You
can increase instance at
run - time as p er th e
need.
• It will take time to
p rocess increased
instances b ut existing
instances will keep
running. In b elow
diagram , it disp lay
memor y p er instance.
Default is 2 GB p er
instance.
• You can star t, stop ,
restar t and ch eck h ealth
state of ap p lication on
click of few b uttons.

24. 24
Build a microser vice web -app using
Following Stack
• Spring Boot
• Spring JPA
• H2 In memory database
• Thymeleaf template (Thymeleaf is a modern server-side Java
template engine for both web and standalone environments
) for building UI.
• REST API using Spring Boot performing CRUD operation
Why Spring Boot-
It comes with the ease of developing REST-service controllers, business services, and data repositories.
• Setup new service by using Spring Boot
• Expose resources via a RestController
• Consume remote services using RestTemplate.

• Extending CrudRepository which in
turn extends
the Repositoryinterface and hence
there is no need of implementing our
own methods.
• CrudRepository provides methods for
the CRUD operations. This interface
extends the Repository interface.
• When you define CrudRepository, you
have to pass two parameters: type of
the entity and type of the entity’s id
field. This interface has the following
methods:
1. S save(S entity)
2. T findOne(ID primaryKey)
3. Iterable findAll()
4. Long count()
5. void delete(T entity)
6. boolean exists(ID primaryKey)

• Develop Application
• Built fat Jar and create
Manifest.json
• Build archive
combining
application.jar and
manifest.json
• Upload into ACCS
• Run Application on
Cloud.

• The application must
be archived with
above-mentioned
formats with
manifest.json in the
root. This will be a
right format of the
archive to upload in
ACCS.
• Define a version of
java to execute. It can
be 7 or 8. It can also
change from UI
console.

40. 40
• Use any zip or tar utility tool
