PRO TIP: T2 and T3 are two different types of Amazon Web Services (AWS). T2 is designed for general purpose workloads such as web servers, development environments, and small databases. T3 is designed for burstable workloads such as video streaming, gaming, and social media applications.
How do I remember EC2 instance types?
The instances are grouped into ‘instance types’ which are optimized for different compute workloads.

- F – FPGA.
- I – IOPS.
- G – Graphics.
- H – High disk throughput.
- T – cheap general purpose.
- D – Density.
- R – RAM.
- M – Main choice general purpose apps.
What are different types of instances?
The instance types can be broadly classified into five different categories as follows.
- General Purpose.
- Compute-Optimized.
- Memory-Optimized.
- Storage-Optimized.
- Accelerated Computing.
What is the cheapest instance type in AWS?
With On-Demand Instance prices starting at $0.0058 per hour, T2 instances are one of the lowest-cost Amazon EC2 instance options and are ideal for a variety of general-purpose applications like micro-services, low-latency interactive applications, small and medium databases, virtual desktops, development, build and

What are the 3 main pricing options with EC2?
Amazon EC2 pricing. Amazon EC2 is free to try. There are multiple ways to pay for Amazon EC2 instances: On-Demand, Savings Plans, Reserved Instances, and Spot Instances. You can also pay for Dedicated Hosts, which provide EC2 instance capacity on physical servers dedicated for your use.
What is the most popular EC2 instance?
EC2 Instance Type Breakdown
EC2 instances come in the following categories: General Purpose: The most popular; used for web servers, development environments, etc. Compute Optimized: Good for compute-intensive applications such as some scientific modeling or high-performance web servers.
Is S3 cheaper than EC2?
Either way, you’re paying for transfer and storage, so it should be cheaper in all cases to just use S3 for file hosting. EC2 should always be more expensive because you’re paying for the time the instance is running in addition to storage and transfer.
Is RDS or EC2 cheaper?
Installing a database server on EC2 and managing it is usually cheaper than RDS. You will have to handle routine management tasks such as backup, recovery, patching, load management, etc., by yourself.
Which is cheaper EC2 or Lightsail?
Amazon Lightsail costs are lower for basic resource usage compared to the On-Demand Instances in EC2.
Why Spot Instances are cheaper?
A Spot Instance is an instance that uses spare EC2 capacity that is available for less than the On-Demand price. Because Spot Instances enable you to request unused EC2 instances at steep discounts, you can lower your Amazon EC2 costs significantly.
How long do spot Instances last?
Defined duration—you can get a spot instance guaranteed to run for a period of 1-6 hours. The longer the defined duration, the lower the discount provided for the spot instance.
When should you not use Spot Instances?
Spot Instances are also not recommended for workloads that are intolerant of occasional periods when the target capacity is not completely available. We strongly warn against using Spot Instances for these workloads or for attempting to fail-over to On-Demand Instances to handle interruptions.
When would you use a spot instance?
You can use Spot Instances for applications and workloads that require a fast network, quick storage, massive amounts of memory, and high computing capabilities. AI- and ML-powered applications can be costly on GPU instances, making Spot Instances the best option.
How much cheaper are spot instances?
Spot Instances are available at up to a 90% discount compared to On-Demand prices. You can use Spot Instances for various stateless, fault-tolerant, or flexible applications such as big data, containerized workloads, CI/CD, web servers, high-performance computing (HPC), and test & development workloads.
What happens if there is no spot instances?
4) If there are no spot instances, in any of the types you have selected, in any of the AZs you have on the ASG, then nothing will launch and the ASG will periodically retry until it reaches the desired capacity.
What’s the difference between on-Demand and spot instance?
What are Spot Instances? An AWS EC2 Spot Instance is an unused EC2 instance which is available for less than the On-Demand price. Spot instances are up to 90% cheaper than On-Demand instances, which can significantly reduce your EC2 costs. A Spot Price is the hourly rate for a Spot instance.
How are spot Instances charged?
You pay the Spot price that’s in effect, billed to the nearest second. You can optionally specify a maximum price for your Spot Instance. If you don’t specify a maximum price, the maximum price defaults to the On-Demand price.
Are Spot Instances free?
With Spot Instances, you pay the Spot price that’s in effect for the time period your instances are running. Spot Instance prices are set by Amazon EC2 and adjust gradually based on long-term trends in supply and demand for Spot Instance capacity. To learn more about pricing, visit the Spot Instance history page.
Do spot Instances get terminated?
The Spot Instance can be terminated if: The Spot price increases above the maximum price that you’re willing to pay per hour per instance. Capacity is no longer available. The Spot request has constraints that can’t be met.
How often are spot instances interrupted?
On average, AWS Spot Instances are interrupted less than 5% of the time – but there can be significant variability depending on the Availability Zone and instance type. Amazon’s Advisor provides specific estimates on how frequently you can expect service interruptions.
