White Paper: Migrating your Existing Apps to the AWS Cloud

http://bit.ly/CloudMigrationStrategy

Early Candidate Targets

• Spikey workloads (e.g. web applications)

• Dev/Test applications and their environments

• Grid computing / 3D / Image Rendering Apps

• Analytics Applications

AND

• Explosive data growth

• Application backup and archiving

• App Disaster recovery options

• Maintain Existing Compliance

• Leverage Previous Investments

• Maintain & Interoperate with Legacy workloads

Network Connectivity (Internet, VPN or Direct Connect)

Assumption:

Application is a self contained atomic unit

Application Tiers and Data can be moved all at one

Common Migration Patters: Move Entire

Developer/Coder:• Wants to predominantly work on their application. And….

A) has little to do with infrastructure the application runs upon; OR

B) “lightly” involved in the underlying infrastructure their application runs on.

Software Engineer/Architect:• Intimately works on all application components and deeply involved in what

infrastructure the solution runs on.

• Jumps in and engineers under the hood for maximum solution performance.

Dev Ops Engineer:• Heavily involved in Continuous Integration/ Continuous Deployment (CI/CD).

• Automates anything and everything possible for maximum change velocity.

Amazon

EC2

Do it yourself (DIY) application deployment – on a virtual machine

EC2 (Virtual Machine) Instance Families

General Purpose: M1, M3 (, T2)

Compute Optimized: C1, CC2, C3, C4

Memory Optimized: M2, CR1, R3

Storage Optimized: HI1, HS1, I2

GPU: CG1, G2

Micro: T1, T2




Amazon

EC2

You bring your application and AWS provide a managed runtime

.Net Java Python

NodeJS Ruby PHP

Docker

Beanstalk supports a range of runtime containers

User Application

Application Service

HTTP Service

Language Interpreter

Operating System

Host

…all wired into the Beanstalk framework

Example Wizard driven deployment from within Visual Studio IDE

(Eclipse also supported)

Automatically Deploy Web Solutions




Amazon

EC2

You bring your application (Chef recipes) and AWS makes it easy to

deploy and operate applications of all shapes and sizes

AWS OpsWorks Primer

A stack represents

your application. One

stack might be used

for staging and

another for

production.

A layer defines how to

setup and configure a

set of instances and

related resources

such as volumes

and software.

Simply tell OpsWorks

where it can find your

code and define any

additional deployment

tasks. Then

OpsWorks will take

care of deploying your

app in your desired

configuration.

Scale your stack based

on time or

load. Clone your

production stack to a

different region. Set

up user permissions and

access. Automate

workflows for common

tasks.

The heart of the OpsWorks Service

Agent on each

EC2 instanceOpsWorkstalks with

Instance Lifecycle and Configuration Hooks

Deploying you Apps via OpsWorks




Amazon

EC2

Declaratively define your entire architecture, applications, OS

deployment scripts, databases and control other AWS services.

For those that want full control of everything – DevOps centric

Templates can take user input to feed configuration values for other sections of the template

{

"Parameters" : {

"KeyName" : {

"Description" : "Name of an existing EC2 KeyPair to enable SSH access to the

instance",

"Type" : "String"

}

},

}

CollaborationShare templates with ease as just

“I just want my app to

run, and I only want

access to machines if I

really need to”

“I want to source control

my entire datacenter

deployment like I would

my configuration files”

Others Services to consider….

Elastic Container Service

• High performance container management service that supports Docker containers and allows you to easily run

distributed applications on a managed cluster of Amazon EC2 instances.

AWS Lambda

• Compute service that runs your code in response to events.

• Lambda starts your code within milliseconds of an event such as an image upload, in-app activity, website click, or

output from a connected device.

CodeCommit, CodeDeply & CodePipeline

• CodeCommit is a secure, highly scalable, managed source control service that hosts private Git repositories.

• CodePipeline continuous delivery and release automation service that aids smooth deployments.

• CodeDeploy is a service that automates code deployments to Amazon EC2 instances.
