aws vcp configuration
TRANSCRIPT
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

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).
