Microservices based application design and deployment

-

In this post, I'll discuss the high level overview of next generation applications design and deployment. 
Microservices is the emerging trend to break down your business functionality in to smaller chunks and deploying/scaling/managing them independently for an enterprise application. However it is the sole & discrete decision of adoption of this software design for existing or new applications in an enterprise.
Consider a small business scenario where we have a web based application called 'Guestbook', consists of following technical components-

 1. Developed using Java/J2EE
2. Services (Microservices) developed using Spring Boot 
3. MySQL Database.
4. ZUUL Proxy for API Gateway
5. Eureka for Service Registry

 Below would be the sample flow of application access as a micro services based software design-
  • As shown above, end user connects to the WebUI.
  • The application's all services/microservices are deployed independently which internally connects to a MySQL database.
  • Now these microservices are registered in Eureka(Service Registry client) which then connects to API Gateway(ZUUL Proxy) and the final service URL will be consumed by the application.

After the application deployment, it is important to manage the containers. Possible option could be Docker swarm, Kubernetes, OpenShift, Amazon ECS etc.
This blog considers Kubernetes as orchestration engine. Below is the diagram to showcase containers management-
  • IT can be clearly seen that GuestbookUI, corresponding microservices & MySQL database has been deployed independently as service. The yellow boxes shows scaled up containers.
  • A ReplicationController ensures that a specified number of pod replicas are running at any one time.

    Data migration service providers like your company helped me in moving the data with stability. You had helped in determining which data is useful to move and how the quality of the data can get changed after the transformation.

Hi Everyone, in this blog I'll be writing one of the strange issue that has been encountered while working with a Oracle SOA composite running in Oracle IDAM environment and trying to invoke a SSL based remote service where SSL certification based exception has been thrown during the service invocation.

Migration of Oracle SOA Suite Composite from 11g to 12c

Recently I have came across a scenario where I have a business requirement of  migration of Oracle SOA Suite 11g(11.1.1.7.0) to 12c(12.1.3.0). Below are the different mechanisms I have tried to do, few of them failed and one succeeded. Working in Oracle SOA Suite 11g is completely different from 12c. In 11g, we need to install the jDeveloper(11.1.1.7) then SOA extension separately to be installed either via offline file  (download available at  https://www.oracle.com/ocom/groups/public/@otn/documents/webcontent/156082.xml ) or through jDeveloper top menu >>  Help >> Check for Updates >> SOA Extension.  While working with 12c doesn't involves such tedious job. Only single installer is required for jDeveloper/SOA/Weblogic and is available as QuickStart Installer(download available at https://www.oracle.com/technetwork/middleware/soasuite/downloads/index.html). Approach 1- Compress(Zip) SOA composite code of 11g version (11.1.1.7.0) and unzip to a differe
