EC2Virtual 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


DatabaseStorageCompute Database

Database

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

Networking

AWS Global AWS Infrastructure

Networking

Route 53Route 53Scalable DNS

• Route end users to Internet applications

• Answers DNS queries with low latency by using a global network of DNS

servers

• Latency based routing to closest AWS endpoint (e.g. EC2 instances, Elastic

IPs or ELBs)

• Application Health Checks

• Deep integration with other AWS services (ELB,

EC2 NAT/EIP, etc.)

• DNS failover

Scalable Storage in the Cloud

Simple Storage Service

• A “Bucket” is equivalent to a “folder”

• Able to store unlimited number of Objects in a Bucket

• Objects from 1B-5 TB; no bucket size limit

• Highly available storage for the Internet (object store)

• HTTP/S endpoint to store and retrieve any amount of data, at any time, from

anywhere on the web

• Highly scalable, reliable, fast, and inexpensive

• Designed to provide annual durability of 99.999999999%

• Designed for 99.99% availability

• Trillions of objects stored

• Peak requests 1,500,000+ per second

Storage

CloudFront

• Web service for content delivery

• Distribute content to end users with low latency, high data transfer speeds, and

no commitments

• Delivers your content using a global network of 52 edge locations

• Supports download, streaming, live streaming, and dynamic content

– Key features: RTMP Streaming, HTTPS Delivery, Private Content for HTTP &

Streaming, Programmatic Invalidation, Detailed Logs for HTTP & Streaming, Default

Root Object

• Use Cases: Video and Rich Media, Online Gaming, Interactive Agencies,

Software Downloads, Static Websites

– Static web content that must be delivered to global user base at Highest bandwidth /

Lowest latency / Lowest cost

IAMSecure 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

CloudWatchResource Monitoring

"Resources" : {

"Ec2Instance" : {

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

}]

}

},



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 BeanstalkAWS Application Container



OpsWorks
