Jump Server — AWS

1. VPC
2. Subnet
3. IGW (Internet Gateway)
4. Route table

Let see how to connect web server to database server

The web server enable the Public IP address its easily connect the machine but the database server not enable the Public IP address purpose need more security. So how to connect the Database (DB) server ?

Below the practical session

1. First the create a VPC

2. Create a Subnet — 3 Subnet create

Successfully create edit the subnet setting and enable the auto assign IP address

Create a 2 subnet the same enable the auto assign IP address

Third subnet no need auto assign IP address — No Public IP address

Finally created 3 Subnets

Create a Internet Gateway

Attach the IGW to VPC

Route table configure

Edit the route table and target select IGW

Split the subnet which subnet need the internet click and save

Create a EC2 instance — 2 machine

One machine select the auto assign IP address subnet — Public IP address

Another one None of IP address — No Public address

Connect EC2 to Mobaxterm Terminal

Internet connected to web server ping google.com

How to connect without public address first login the webserver after login the DB server but now access denied. Why?

.pem file is not there in ec2 machine so moved to the Ec2 VM

Once move to .pem file now its try its connected

If check internet is working or not, the internet is not working

The concept of “JUMP SERVER” most of the organisation used this way
