This recipe explains what are different types of EC2 instances based on their costs

Types of EC2 instance

What Are On-Demand Instances?

On-Demand Instances are the main EC2 deployment model on the AWS. This price option enables you to immediately purchase continuous Amazon cloud computing resources utilizing a pay-as-you-go model.

You are only charged for the EC2 instances that you actually use, and the pricing is hourly or per-second based.

Although the prices are constant, it is important to keep in mind that the exact charges per instance are not universal; rather, Amazon's On-Demand pricing schedule outlines various rates based on the server area and EC2 instance type.

For instance, compared to A1.large or T3.nano, T3.large instances have different On-Demand pricing rates. The same holds true for deployments in Asia and Europe versus US-based on-demand instances.

The positive thing about On-Demand Instances is that they don't necessitate a lot of preliminary investigation, despite the fact that the many variations first could feel overwhelming. The processing capacity you initially select is not set; you can freely upscale and downscale it by modifying the instances in accordance with the requirements of your application.

Amazon's On-Demand Instances also provide you complete control over their lifecycle. This means that you are free to decide when to deploy, terminate, reboot, start, or hibernate the EC2 instances and are not required to make a long-term commitment.

Simply put, on-demand instances are Amazon's approach of enabling you to freely buy or scale any amount of EC2 capacity based on the immediate requirements of your business.

All of this flexibility, though, has a price. The On-Demand Instances are the ones with the highest prices in the EC2 pricing schemes offered by Amazon.

What Is A Spot Instance?

With the use of a specialized Amazon Web Services (AWS) instance called a spot instance, you can access and utilize unused EC2 capacity at a much reduced cost. They are made available by Amazon to help EC2 users reduce their cloud computing costs by utilizing unused EC2 capacity rather than solely relying on the more expensive On-Demand Instances.

The price you must pay in exchange is referred to as a Spot Price, and it is assessed hourly for each Spot Instance.

The pricing for Spot Instances is variable, despite the fact that they are often less expensive than typical On-Demand Instances. Instead, they are continually changed according to market need across the Availability Zones.

Users cannot rely on real-time bidding in the interim. When EC2 capacity is available and the maximum rates for your request are greater than the Spot Price, the system will operate your Spot Instance.

The real kicker is right here. The Spot Instances may be reclaimed by AWS at any time, it turns out. After giving you a two-minute warning and a Spot Instance Termination Notice, the system will proceed to permanently remove the Spot Instances back.

However, these service outages are actually quite uncommon. Amazon claims that less than 5% of the time is spent terminating Spot Instances.

However, using Spot Instances in mission-critical settings that demand high availability might not be a wise option. Instead, use them to create fault-tolerant, adaptable workloads that can withstand interruptions.

Examples include batch tasks, data analysis, optional jobs, and background processing.

What Is a Reserved Instance in AWS?

The formal term for an AWS reserved instance is "billing discount," which is applied to the use of an on-demand instance in your account. In other words, a reserved instance is a discounted billing that you receive when you commit to utilizing a specific on-demand instance for a lengthy period of time, such as one or three years.

Reserved instances are the best choice for regular and reliable usage. Compared to on-demand instance pricing, they can help you greatly reduce your Amazon EC2 costs because the hourly rate is significantly reduced in return for your agreement to pay for all the hours in a one-year or three-year period.
