Cloud Native

DevOps Continuous Delivery

Containers Micro services


Microservices are key for CLOUD NATIVE JAVA

Application Framework

Infrastructure Automation

Platform Runtime

Language framework for microservice-based architectures including components for service discovery, metrics and circuit breakers.

Application container runtime with attachable backing services, automated CI/CD, routing, health management and logging.

A single deployment API for provisioning for bit-for-bit, consistent, self-healing deployments across any private or public cloud.

DEMO!


Enhanced Application with Spring Boot package hello;import java.util.Arrays;

import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.ApplicationContext;

@SpringBootApplicationpublic class Application {

public static void main(String[] args) { SpringApplication.run(HelloSpringBootApplication.class, args); }

}

MAGIC!!

•  Tags the class as a source for Spring Beans

•  Asks Boot to automatically add beans based on classpath

•  Tell Spring to look for other components, configs etc. in the same package


Simple Spring MVC with Annotations package hello;

import org.springframework.web.bind.annotation.RestController;import org.springframework.web.bind.annotation.RequestMapping;

@RestControllerpublic class HelloController {

@RequestMapping("/") public String index() { return "Greetings from Spring Boot!"; }

}

Ready for SpringMVC to handle Web requests

Maps ‘/’ to this method

Elastic Runtime High Level Architecture

•  Turnkey, fully automated Platform-as-a-Service

•  Scalable runtime environment, extensible to most modern frameworks and languages running on Linux

•  Instant expansion or upgrade with no downtime

•  Deploy, scale and manage applications with bindable services using simplified semantics and APIs

Containers Pre-date the Docker Hype

Google started Linux container effort “Control

Groups”

Added to the Linux Kernel in

2007

Cloud Foundry uses Linux container

technology - “Warden

containers” early 2012

Docker is like github for container images

Docker joins Cloud Foundry

Foundation

Google, MSFT, IBM working on orchestration of multiple Docker

containers

2006 2014

Cloud Foundry has been using container technology pre-Docker

2012


BUILD PACKS


Platform provides standard Buildpack for runtime*

Platform provides fixed OS container image

Developer brings app
