1. Can you identify at least three configuration elements that comprise a VPC configuration?2. When creating VPC subnets, what type of access do they have to each other by default?3. How are you able to connect to ECZ Classic instances by VPC?

Benefits of VPC:

Control over the network elements of AWS

Multiple static ip addresses assignment of EC2 instances

VLAN like configuration inbound/outbound filtering

increased security - security groups + NACLs (Network Access Control List)

Single tenant hardware options

key to VPN configuration

Setting up VPC:

Elements of :

The master subnet must be between /16 --> /28

Subnets : the "subnets" of the VPC

internet gateway

Route Tables

Elastic Ips

Security Groups - NACLs

VPN connection

Configuration

Select the region of North Virginia

Select VPC Dash board ->

Start VPC wizard ->

Single Public subnet ->

Click on Create VPC

Step2 : - instances - >

launch instance ->

ubuntu server ->

Review and launch / configure instance details ->

launch ->

check box Acknowledge and click on launch instances

2. VPC : Te Nitty Gritty Configuration

1. What is the function of the VPC Table? How do you apply it?2. What Defines the VPC?(What is the primary attribute?)3. Are you able to manually configure (Non-Wizard) a complete VPC Environment?

6. VPC Design for High Availability

Summary

Understanding direct connect HA Design and Communication

Design for HA NAT

Application and Session State HA

Do i know this?

1. What AWS Elements creates HA for incoming request between Availability Zones?

2. What is one draw back to boot strapping vs using a Golden AMI

3. Do you have the ability to move an ENI between subnets/AZ?

Direct Conect is

Partnet Data Center

Elastic Network Interfaces [ENI]:- it is a component of High Availability

All Instances start with eth0 - cant move it

using ENI allows you to move interfaces quickly

Avoid DNS issues.

simple fall back

it works only within the same availability zone(az/ subnet).
