Agenda
AWS Global Infrastructure
AWS has around 9 different Regions located throughout the world
Each Region contains two or more availability zones.
The AWS regions are isolated from each other.
Multiple Network connected available zones in each region
AWS Infrastructure
• Regions are separate clouds
• Multiple Network connected available zones in each region

Edge locations serve requests for CloudFront and Route 53.
Cloud Front is a content delivery network.
Route 53 is a DNS service

Different Components in VPC
AWS provides two ways for you to control security in VPC
• Security groups
• Network ACLs.
They both enable you to control what traffic goes in and out of EC2 instances, but security groups work at the instance level, and network ACLs work at the subnet level.

Feature Description
Support for VPC in multiple Availability Zones in each Region
You can create a VPC that spans multiple Availability Zones in a Region. Since each VPC can have multiple subnets, you can put each subnet in a distinct Availability Zone. Virtual private gateways and Internet gateways are regional objects, and can be accessed from any Availability Zone.
Support for multiple VPN Connections per VPC
You can create multiple VPN connections to a single VPC. This can be used to connect multiple branch offices to a single VPC, or to provide redundant VPN connections from a single location.
VPN Connection Status You can view the status of each VPN Connection on the AWS Management Console and via API/CLI.
Status includes connection state (up or down), tunnel state, time since last state change, and descriptive text for connection errors.
Support for multiple VPCs per AWS account per Region
You can create multiple, fully-independent VPCs in
a single Region without having to use additional
AWS accounts. You can, for example, create
production networks, development networks,
staging networks, and test networks as needed.

Amazon Elastic Block Store (EBS) provides block level storage volumes for use with Amazon EC2 instances.
Amazon EBS volumes are network-attached, and persist independently from the life of an instance.
Amazon EBS allows you to create storage volumes from 1 GB to 1 TB that can be mounted as devices by Amazon EC2 instances. Multiple volumes can be mounted to the same instance.
Amazon EBS enables you to provision a specific level of Input Output performance if desired, by choosing a Provisioned IOPS volume. This allows you to predictably scale to thousands of IOPS per Amazon EC2 instance.
Elastic Block Storage(EBS)
Amazon EBS also provides the ability to create point-in-time snapshots of volumes, which are persisted to Amazon S3.
These snapshots can be used as the starting point for new Amazon EBS volumes, and protect data for long-term durability. The same snapshot can be used to instantiate as many volumes as you wish.
Once a volume is created, it can be attached to any Amazon EC2 instance in the same Availability Zone.
Each storage volume is automatically replicated within the same
Availability Zone. This prevents data loss due to failure of any single hardware component.
Elastic Block Storage(EBS)
A volume can only be attached to one instance at a time, but many volumes can be attached to a single instance.
If an instance fails or is detached from an Amazon EBS volume, the volume can be attached to any other instance in that Availability Zone .
Elastic Block Storage(EBS)
Amazon Elastic Compute Cloud (Amazon EC2) is a web
service that provides resizable compute capacity in the cloud.
Amazon EC2 presents a virtual computing environment,
allowing you to use web service interfaces to launch instances with a variety of operating systems.
EC2 provides multiple instance types from micro to high memory cluster instances.
There are three ways to launch the EC2 instance.

Elastic Load Balancing automatically distributes incoming application traffic across multiple Amazon EC2 instances in a single Availability Zone or multiple Availability Zones.
Reroutes traffic to healthy instances until the unhealthy instances have been restored.
Elastic Load Balancing supports the ability to stick user sessions to specific EC2 instances.
