Within my last post the Camunda Spring-Boot Starter application used a h2 in-memory database. In general this is a good approach while developing and testing, but it should be replaced by a persistent database in later development and production stages. Using Spring-Boot capabilities this can be easily achieved by configuration. Within this post we will create a Camunda Spring-Boot starter database configuration which uses h2 in-memory database during automated tests only. For all other scenarios a MySQL database is used.

In course of my current project I experimented with Camunda BPM Spring-Boot starter throughout this week. Within this post Camunda Spring-Boot project setup using Apache Maven will be described.

After looking into how to run a Spring-Boot based Microservice application on Oracle’s Application Container Cloud service, this post will concentrate on Oracle Container Cloud Service. In short, Oracle Container Cloud Service is Oracle’s enterprise-grade container infrastructure solution. It provides features to compose, deploy, orchestrate and manage Docker container-based applications. In contrast to Oracle Application Container Cloud Service customers can completely control containers deployed within this infrastructure. Therefore, this service provides the highest amount of flexibility for container-based applications. On the other hand, it does not relieve customers of tasks like Oracle Application Container Cloud Service.

In my last post I gave an introduction to Oracle Application Container Cloud (ACC) and how to develop Spring-Boot applications such that they can be hosted within Oracle ACC. At the end of the post some questions still had to be answered. Within this post we are going to tackle the first one, how is Microservice Communication in Oracle Application Container Cloud achieved? The following figure shows what a simple architecture, within the context of a Spring-Boot Microservice application, might look like.

Microservices as an architectural style as well as scalable and manageable cloud infrastructure are the foundation for modern and flexible business applications. Therefore, Oracle invested heavily in maturing its Cloud portfolio and providing services to support development and operations of such applications. One Oracle cloud service aimed at these kind of applications is “Oracle Application Container Cloud Service” (ACC). It provides a simple Docker based environment in which your Microservices can be deployed. In order to reduce the operations overhead, developers only have to provide their applications (NodeJS, Java SE or PHP) in a certain format and Oracle’s cloud infrastructure takes over.
