AWS VPC Elastic IP service limits should not be breached

AWS-VPC-Elastic-IP-service limits

AWS service limits are restrictions put on the number of resources that a particular user can consume. These restrictions are imposed to prevent new users from utilizing way too much on resources. Having said that, Amazon VPC is the virtual network service that too has certain limits defined for its resources per region per user (for each AWS account). Let us first deep dive into the usage limits of AWS VPC Elastic IPs.

What are AWS VPC Elastic IPs?

AWS VPC elastic IPs are static IPv4 based IP addresses which are used for the purpose of dynamic cloud computing. Elastic IP addresses can be associated with any number of resources such as instances or network interfaces for any VPC in your AWS account. You can use these IPs to mask the failure of your resources.

Elastic IPs can rapidly remap the resource address to another similar resource in your VPC. For e.g. – you can remap a failed instance address to another instance address associated with a VPC in your cloud.

Track your Elastic IPs service limit for better resource management

There is a defaut limit on the no. of Elastic IPs that you can have in a particular AWS region. Users should be aware of that limit which will help them avoid the misuse of resources thus, contributing to a healthy cloud environment.
