Fix Unreachable EC2 Instance

It is very painful to set up the server again and again for the same application when the instance suddenly goes down due to some unavoidable reason like a boot error, memory limit exceeds, corrupt file system, incorrect networking, or any other issue.

But wait, AWS provides a “Launch More Like This Image” feature to save our time and effort to set up the instance from the very beginning and installing all the libraries again. Also, sometimes this feature saves our time in the case when we need to set up multiple servers for the same type of application like to host websites.

STEP 1

Right-click on the instance

Image and templates -> Launch more like this

STEP 2

It will directly jump to “Review Instance Launch” wizard

By default, all the instance configuration setting is exactly the same. Still, we can edit the info while reviewing it.

Click on “Launch”

STEP 3

Create a key or use the existing one.

Click on “Launch Instances”

STEP 4

The instance is created.

We can create “templates” of instances as well. It will help us to create instances quickly. But in this case, we need to install all the required libraries again as it does not copy the image.
