Developer Challenges

  Complexity of deploying code, provisioning and managing infrastructure   Expertise and time needed to manage and configure servers, databases, load balancers, firewalls, and networks   How to automate application scaling

DevOps changes how you are used to working


What if you could just focus on your app ?

APP and a TOOLBOX for

DEPLOYMENT, ENVIRONMENTS and INFRASTRUCTURE


YES! You can, with AWS Elastic Beanstalk!

APP AWS Elastic Beanstalk


Okay let’s get started!


AWS Elastic Beanstalk

 Easy to use Service  Deploy and Scale Web Apps  Don’t Sweat the Small Stuff


AWS Elastic Beanstalk Your code

HTTP server

Application server

Language interpreter

Operating system

Host

•  Each Amazon EC2 instance comes with the necessary components to run applications

•  No more worrying about

logging into instances to install and configure your app stack

Focus on building your app


Components of a Web App •  Three tier architecture:

•  Web Server •  App Server •  Database

•  Components •  Application Compute •  Database Engine •  Storage and Delivery


AWS Elastic Beanstalk - EB •  Easily deploy, monitor, and scale applications •  Infrastructure provisioned and managed by EB.

You maintain complete control. •  Preconfigured application containers that are

easily customizable.


AWS Elastic Beanstalk Environment

•  Two tiers •  Web Server

•  Worker

•  Two types: •  Single instance

•  Load balanced, auto scalable

•  Configures Amazon Route 53 and provides a domain name

Application Versioning

Saved Configurations Allow for easy duplication for A/B testing or non-disruptive deployments

Application Versions All versions are stored durably in Amazon S3. Code can also be pushed from a Git repository!


The Common Used Deployment Options


Deployment Options

1.  Via the AWS Management Console

2.  Via Git / EB CLI

3.  Via the AWS Toolkit for Eclipse and the Visual Studio IDE

$pipinstallawsebcli


Example: CLI workflow

Initial app deployment:

$gitinit. $gitadd.Initialize your Git repository 01 Add your code 04

$ebinit $gitcommit–m“v1.0”Create your Elastic Beanstalk app 02 Commit 05

Follow the prompts to configure the environment 03 Create the resources and launch the

application 06

$ebcreate


Example: CLI workflow

Update your app:

Update your code 01

$gitadd.$gitcommit–m“v2.0”$ebdeploy

Push the new code 02

Monitor the deployment progress 03

$ebstatus


Docker with AWS Elastic Beanstalk


Docker with AWS Elastic Beanstalk

 Single Docker Container

 Multiple Docker Containers


Multi Container: Architecture

  Each environment has its own ECS Cluster   Supports a single ECS Task

definition per environment   The ECS Task is defined in

the Dockerrun.aws.json file   Supports multiple ELB

listeners for inbound traffic   Provides out of the box auto

scaling for ECS Tasks

Task 1-1 Task 1-2

Container 1 Container 1

ELB

Instance 1 Instance 2

Container 2

Container 3

Container 2

Container 3


Multi Container Dockerrun.aws.json

{ "AWSEBDockerrunVersion": 2, [...] }

the value "2" for multicontainer Docker environments


Multi Container Dockerrun.aws.json "containerDefinitions": [ { "name": "php-app",

"image": "php:fpm", "essential": true, "memory": 128,

},


Multi Container Dockerrun.aws.json "links": [

"php-app", "list-service", "search-service”

]


Multi Container Dockerrun.aws.json

"mountPoints": [

{ "sourceVolume": "php-app", "containerPath": "/var/www/html", "readOnly": true }

]

"volumes": [ { "name": "php-app", "host": { "sourcePath": "/var/app/current/php-app" } } ]
