Key Advantage of Amazon EC2 from a Cost Perspective

Answer - C.

One of the advantages of EC2 Instances is the per-second billing concept.

This is also given in the AWS documentation.

With per-second billing, you pay for only what you use.

It takes the cost of unused minutes and seconds in an hour off of the bill.

So, you can focus on improving your applications instead of maximizing usage to the hour especially if you manage instances running for irregular periods of time, such as dev/testing, data processing, analytics, batch processing and gaming applications.

Sure, I'd be happy to provide a detailed explanation of the advantages of Amazon EC2 from a cost perspective.

Amazon Elastic Compute Cloud (EC2) is a web service that provides resizable compute capacity in the cloud, allowing you to scale your computing resources up or down as your requirements change. Here are some of the advantages of Amazon EC2 from a cost perspective:

A. Having the ability of automated backups of the EC2 instance, so that you don't need to worry about the maintenance costs.

Automated backups can help you reduce maintenance costs by eliminating the need to manually create and manage backups. Amazon EC2 provides automated backup capabilities that allow you to take regular snapshots of your instances, which can be used to restore data or recreate the entire instance if necessary. By using automated backups, you can save time and resources while also ensuring that your data is protected.

B. The ability to choose low-cost AMIs to prepare the EC2 Instances.

Amazon Machine Images (AMIs) are pre-configured virtual machine images that you can use to launch EC2 instances. You can choose from a wide variety of AMIs, including low-cost options, which can help you reduce your overall EC2 costs. By selecting the appropriate AMI, you can ensure that you are only paying for the features and resources that you actually need.

C. The ability to only pay for what you use.

One of the primary advantages of cloud computing is the ability to pay only for the resources that you use. With Amazon EC2, you can choose from a variety of pricing models, including On-Demand, Reserved Instances, and Spot Instances. This allows you to select the most cost-effective option for your specific use case. Additionally, Amazon EC2 provides tools and services to help you monitor and optimize your usage, which can help you further reduce costs.

D. Ability to tag instances to reduce the overall cost.

Tags are metadata that you can assign to your Amazon EC2 instances to help you categorize and manage your resources. By using tags, you can easily identify and manage your instances, which can help you optimize your usage and reduce costs. For example, you can use tags to identify instances that are not being used or that are overprovisioned, and then take action to reduce or eliminate those resources.

In conclusion, Amazon EC2 provides a number of cost-saving advantages, including automated backups, low-cost AMIs, pay-as-you-go pricing, and tagging capabilities. By taking advantage of these features, you can optimize your usage and reduce your overall costs when moving resources to the AWS Cloud.
