Business Logic

Data handling

UI

• Single package• Not distributed• Straightforward to develop

• Often becomes large and complex• Required to deploy as single

package – even for small updates• Difficult to push updates out fast

MONOLITHIC ARCHITECTURE

• Application becomes independant services

• Fast to update, replace, deploy, scale

• Requires mature CI/CD pipeline (DevOps)

• Complex coordination, management

• New skills needed

WHY JAVA IN THE CLOUD?

WHY JAVA?

● Standardized, open platform built by collaboration

● Large existing skill sets

● Choice (Hardware, OS and vendor)

● Ease of development

● Maturity

WHY JAVA AND THE CLOUD?

● Extend Java knowledge and expertise to the cloud

● Modernize for web-scale, highly transactional apps

● Scaling, provisioning, standardized environment

● Containers & orchestration

● Deliver faster, with automation

OPENSHIFT BY RED HAT

OpenShift is Red Hat’s Container Application Platform

● Built for both traditional and cloud-native applications.

● An integrated hybrid cloud application platform for application development and deployment

● Develop, build, and manage container based applications

● Easily turn source code into running applications with source-to-image capabilities

RED HAT INTERNAL ONLY

“Most teams we work with favor bundling an embedded http server within your web application. There are plenty of options available: Jetty, SimpleWeb, Webbit and Owin Self-Host amongst others. Easier automation, easier deployment and a reduction in the amount of infrastructure you have to manage lead us to recommend embedded servers over application servers for future projects”

ThoughtWorks Technology Radar, May 2015

• Just enough Java EE for building and deploying RESTful microservices

• Lightweight• Embeddable (fat-jar)• Modular and extensible• Built from Wildfly

● Reducing downtime and risk associated with release

● Two identical environments in containing two different releases (Blue and Green)

● After validating new release, can switch all traffic to new version

● Quickly roll application back if you find issues
