How does elastic ip differ from public ip?
The Elastic ip its fixed public IP until we release this elastic ip, we can reuse it new EC2 instances, its static ip even the instance restarts IP remains the same, where the Public IP assign to EC2 instance to access internet but when we restart/stop/terminate this IP will be changed new one.
What is Amazon elastic Load Balancing?
It is a fully managed service in AWS that automatically distributes incoming application traffic across multiple targets, such as Amazon EC2 instances, containers, IP addresses, and Lambda functions. It operates across multiple Availability Zones to increase the fault tolerance of your applications.
In short Instead of all the traffic going to a single server, the load balancer spreads the requests across multiple servers, ensuring no single server is overcrowded. This improves the availability and responsiveness of your applications.
What is an elastic IP in AWS?
an Elastic IP provides a stable, predictable public IP address for your cloud resources, enhancing reliability and simplifying management, especially in scenarios requiring consistent external connectivity or failover capabilities.
How does AWS elastic IP work?
an Elastic IP provides a stable, portable public IP address for your AWS resources, enhancing the resilience and manageability of your cloud infrastructure. You allocate it, associate it with an instance (or network interface), and can remap it as needed, ensuring your public endpoint remains consistent. Remember to release EIPs you are no longer using to avoid incurring costs.
How does elastic ip differ from public ip?
For example if we need to connect to the internet temporarily we can use public Ip which keeps changing whenever we stop or terminate the instance. Whereas the Elastic Ip are static and persistant in nature where we can completely reply on these Ip when there is an instnace failure and many more without changing the Public Ip.
Also make sure to release the Elastic Ip when no longer in use to avoid the unnecessary charges.
