Route Tables

• With Every VPC a Route table gets created.
• Default Route table will have the main value as Yes
• We can create route tables
• Associate Route tables to Subnets
• Scenario:

Exercise: Create the VPC as shown above and simulate bastion host scenario

• Create one ec2 machine in public subnet
• Create one ec2 machine in private subnet
• Now using public subnet connect to private subnet

Other info

• By default DNS name for public ip is disable on any user created vpcs
• Bastion Host: Bastion Host is an ec2 instance present in public subnet which helps to connect to private subnet’s ec2 instance. (Jump Box also does the same job)
