Sufyaan Kazi (@sufyaan_kazi) & Sara Mitchell Manager, Field Engineering UK & I

Powering Digital Transformation Pivotal enables enterprises to provide

modern software-driven experiences for their customers and workforces.

Modern Approach for Digital Business

AGILE PRODUCT DEVELOPMENT

Agile practices and collaboration for product and culture transformation

•  World class application development services

•  Proven transformational methodology

BIG DATA Modern, open, highly parallelized platform

•  Hadoop, in-memory, and database software

•  Industries most complete big data analytics offering

CLOUD NATIVE PLATFORM Modern, open, highly

automated cloud platform

•  Platform-as-a-Service (PaaS) software with multi-cloud support

•  Record-breaking sales growth and adoption

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.

Dev Ops

Spring Cloud

Spring Boot

Contract: 12 Factor Application

Contract: BOSH Release

Spring Boot

Dynamic language productivity with maturity of enterprise Java Cloud Native: Direct support for Microservices, NetflixOSS++ Fully automated app server configuration and deployment Production ready Ops metrics out of the box, with a switch

Spring Boot Capabilities

•  Quick start project generation •  Automatic project dependency mapping •  Configuration drift prevention •  Conditional configuration with profiles •  Developer productivity tooling •  Auto configuration •  Monitoring and management endpoints •  Micro-services friendly

Spring Boot From 0 to app in < 5 min

Enterprise Java with dynamic

Spring Cloud Designed for fragile infrastructure in

partnership with Netflix

Java Microservice Framework 100% Spring Boot enabled

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

Spring Boot Actuator Actuator, production ready features exposed as endpoints. There are many built-in endpoints but this can be extended.

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

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

BUILD PACKS

Platform provides standard Buildpack for runtime*

Platform provides fixed OS container image

Developer brings app

Developer brings runtime Docker image

Developer brings Docker OS image

Buildpacks Docker

* Devs may also provide their own buildpacks
