EC2 Virtual servers in the cloud

Elastic Compute Cloud

• Resizable compute capacity in 30+ instance types

• Reduces the time required to obtain and boot new server instances to minutes

or seconds

• Scale capacity as your computing requirements change

• Pay only for capacity that you actually use

• Choose Linux or Windows

• Deploy across Regions and Availability Zones for reliability

• Support for virtual network interfaces that can be attached to EC2 instances in

your VPC

Compute

Amazon Machine Image

• Building blocks of EC2 instances

• An AMI is like a template of a computer's root volume.

• Can be public or private and shared with other accounts

• Create hardened or gold “Images” of your EC2 infrastructure

• Copy AMIs between regions

Compute

Elastic Block Storage (EBS)

• Use for persistent storage from 1GB – 1TB

• Can use to create RAID configuration for a server

• Off-instance block storage that persists independently

• Storage volumes for use with Amazon EC2 instances – create, attach, backup,

restore and delete

• Can be attached to a running Amazon EC2 instance and exposed as a block

device for raw or formatted (file system) access

• Snapshots are durably saved to S3

• Ideal use cases:

– OS Boot device / root file system; secondary volumes/file systems

– Typical basis for database storage

– Raw block devices for RAID, some databases

• Available in both standard and provisioned IOPS (up to 4k IOPS)

Compute

Auto Scaling

• Client Defined Business Rules

• Scale your Amazon EC2 capacity automatically once you define the conditions

(may be 1000’s of servers)

• Can scale up just a little…doesn’t need to be massive number of servers (may

be simply 2 servers)

• Well suited for applications that experience variability in usage

• Set minimum and maximum scaling policies

• Alternate Use is for Fault Tolerance

Compute

Elastic Load Balancing

• Supports the routing and load balancing of HTTP, HTTPS and generic TCP

traffic to EC2 instances

• Supports SSL termination and Proxy protocol

• Supports health checks to ensure detect and remove failing instances

• Dynamically grows and shrinks required resources based on traffic

• Seamlessly integrates with Auto-scaling to add and remove instances based

on scaling activities

• Single CNAME provides stable entry point for DNS configuration

• Supports internal load balancing within a VPC

Networking

Database Storage Compute Database

Database

DynamoDB Scalable NoSQL Data Store

Relational Database Service

• Fully-managed, tuned MySQL, PostgreSQL, Oracle 11g, or MS SQL

• Cost-efficient and resizable capacity

• Manages time-consuming database admin tasks

• Code, applications, and tools you already use today work seamlessly

• Automatically patches the database software and backs up your database

• Flexible Licensing: BYOL or License Include

• Multi-AZ deployment option for MySQL, PostgreSQL and Oracle

• Cross-Region Read Replica support for MySQL

RDS Managed Relational Database Service

Networking

Database Storage Compute

IAM Secure AWS Access Control

CloudFormation

• Create templates of stack of resources

• Deploy stack from template with runtime parameters

• Templates are simple JSON formatted text files

• CloudFormer supports generating templates from running environments

CloudWatch Resource Monitoring

CloudFormation Templated AWS Resource Creation

"Resources" : {

"Ec2Instance" : {

"Type" : "AWS::EC2::Instance",

"Properties" : {

"SecurityGroups" : [ { "Ref" : "InstanceSecurityGroup" } ],

"ImageId" : { "Fn::FindInMap" : [ "RegionMap", { "Ref" : "AWS::Region" }, "AMI" ]},

"Tags" : [{

"Key" : "MyTag",

"Value" : "TagValue"

Elastic Beanstalk

• Simply upload your application (Java, NET, PHP, Node.js, Ruby and Python)

• Automatically handles the deployment details of capacity provisioning, load

balancing, auto-scaling, and application health monitoring

• Retain full control over the AWS resources powering your application

Elastic Beanstalk AWS Application Container

OpsWorks

• DevOps service for applications in the AWS cloud

• Helps manage complete application lifecycle:

– Resource provisioning

– Configuration management

– Application deployment

– Software updates

– Monitoring

– Access control

• Visualized through application layers

• Uses Chef recipes used to deploy and configure software components on EC2

instances
