How to upgrade AWS instance RAM without elastic IP address

If you restart an AWS EC2 server that doesn’t have an Elastic IP (EIP), it might get a different public IP address. This may have a number of drawbacks:

  • IP Address Change: Your EC2 instance’s public IP address is usually dynamic if you don’t have an Elastic IP. This implies that it is subject to change upon stopping and restarting the instance. If you rely on a consistent IP address to whitelist IP addresses in firewalls or security groups, or to access services hosted on the instance, this could be an issue.
  • DNS Consideration: If you can reach your instance by domain name after restarting, you may need to change the DNS records. People who try to use your services might have outages or connection issues because of this.
  • Service Interruptions:After the DNS records are changed and the updates propagate to all hosts, the IP address alteration could lead to service interruptions. This is particularly critical for essential services reliant on a stable IP address, such as a web server or database.
  • Security Configuration: You might have to adjust security groups or network ACLs you’ve set up to permit access from particular IP addresses each time one changes. This adds administrative labor and raises the possibility of security issues if done incorrectly.
After updating the RAM on your AWS EC2 instance, if you find the need for a permanent IP address and there is no existing Elastic IP assigned to it, you can proceed by following these steps:

1. Assign an Elastic IP (EIP): Open the AWS Management Console and navigate to the EC2 dashboard.

Choose “Elastic IPs” under “Network & Security”.

To assign a new Elastic IP, click “Allocate new address” and follow the instructions.

2. Link the Elastic IP to your EC2 instance: Choose the newly assigned Elastic IP from the Elastic IPs dashboard.

After selecting “Actions”, proceed to select “Associate address”.

Proceed with the association procedure after selecting the EC2 instance from the dropdown menu.

3. Verify the association: After the association is finished, make sure your EC2 instance and the Elastic IP are correctly linked.

4. Upgrade the RAM:
  • To update the RAM, you must first stop the EC2 instance. Consequently, while the instance is operating, it cannot be altered.
  • Backup Vital Information: As a courtesy, make sure you have backups of all vital information stored on the instance.
  • Type of Instance: Not every EC2 instance type is compatible with RAM upgrades. It is necessary to confirm whether the type of instance you are using supports RAM upgrades. If not, you might have to transfer your data and start over with the appropriate amount of RAM.
  • Instance Size: You usually need to enlarge the instance to a larger size that supports the necessary RAM capacity, if the instance type permits a RAM upgrade. This could entail switching to a bigger instance type with greater RAM.
  • Restart Instance: Restart the EC2 instance after increasing its size.

5. Test and Verify: After upgrading and restarting the instance, it’s imperative to confirm that the Elastic IP remains linked to it and that it operates seamlessly with the additional RAM.
