Spot price AWS is a type of pricing model offered by Amazon Web Services (AWS). This pricing model allows customers to bid on unused Amazon EC2 compute capacity, allowing them to significantly reduce their compute costs when compared to traditional On-Demand or Reserved Instance pricing models.
It is especially beneficial for short-term workloads that are variable or unpredictable in nature, such as research or testing projects, or tasks with specific time constraints. Additionally, Spot Instances can be used to supplement On-Demand and Reserved Instance capacity when demand is high.
When bids are accepted, Spot Instances are made available at the requested price, with an Amazon EC2 Service Level Agreement (SLA) of 99. 5% or greater. If demand shifts or the spot price rises, Amazon automatically shuts down the instance without any additional charges.
The Spot price exists in every AWS region, and is based on the supply and demand for spare capacity. The price for a Spot instance can go up or down frequently, which is based on customer bids, availability, and other factors.

How does AWS spot pricing work?
AWS spot pricing is a cost-saving option that allows customers to bid on unused Amazon EC2 capacity, up to 90% off the On-Demand price. The Spot price fluctuates based on supply and demand of EC2 instances in the AWS Marketplace.
To request Spot Instances, customers submit a bid, which is the maximum price they are willing to pay for the EC2 instance. If the Spot price is higher than their bid, the instance will not be launched.
When the Spot price is lower than the bid, the instance will launch and run until the current Spot price exceeds the bid or the customer terminates the instance.
AWS also provides features, such as Spot Fleet and Spot Block, to help customers manage Spot Instances and maximize savings. Spot Fleet allows customers to combine Spot, On-Demand, and Reserved Instances into a single fleet of EC2 instances, while Spot Blocks proactively reserves capacity to customers over a specific period of time.
In addition, customers can use Spot Instances to run large-scale, fault-tolerant, and mission critical applications that are resilient to instance interruption. AWS Spot Instances are designed and tested to handle interruption gracefully and are automatically restarted in a nearby Availability Zone when interrupted.
To sum up, AWS Spot Pricing provides customers with a cost-effective way to save money on EC2 instances and run large-scale, fault-tolerant applications with low interruption risk. With the variety of features and cost saving opportunities, customers are able to maximize their budget and have the flexibility to scale up or down as needed.
What is AWS spot market?
The AWS Spot Market is a resource available on Amazon Web Services (AWS) that allows customers to purchase Amazon EC2 computing capacity at discounted prices. The Spot Market enables customers to bid on unused Amazon EC2 computing capacity, and when their bid is accepted, the computing capacity is committed to the customer and runs until its completion or the end of the bid period.
Customers can purchase capacity in the Spot Market for applications that can take advantage of AWS’s low prices, such as long-running batch processing jobs that benefit from cost savings.
Using the AWS Spot Market, customers can bid on unused Amazon EC2 computing capacity by specifying a price and a duration for their bid. AWS evaluates the bids, and if the price is higher than the current Spot price, AWS will accept the customer’s bid and commit the computing capacity to the customer for the specified period.
The customer can then use the computing capacity for their applications. If the Spot price exceeds the customer’s bid, their bid will be cancelled and the customer will no longer be able to use the computing capacity.
The spot market price is determined by Amazon based on supply and demand, allowing customers to take advantage of a discount on unused capacity. This can be a great way for customers to save on their compute costs.
It is important to note that the Spot Market is a best effort service, so customers should not use the Spot Market for applications that require specific capacity levels or require the capacity to be available without interruption.
What are the 3 pricing models of AWS?
The three pricing models offered by Amazon Web Services (AWS) are On-Demand Instances, Reserved Instances, and Spot Instances.
On-Demand Instances are the most commonly used pricing model of AWS. With this option, you pay for the compute resources you use by the hour, with no upfront commitment or long-term contract. It provides instant access to resources and is ideal for short-term projects or unpredictable workloads.
Reserved Instances are an AWS pricing model that allows customers to make a one-time, upfront payment to receive discounted hourly prices compared to On-Demand Instances. Reserved Instances provide considerable cost savings when compared to On-Demand Instances and are ideal for customers who want to make a long-term commitment to use AWS services.
Spot Instances are an AWS pricing model that provides access to compute resources at up to 90% less than On-Demand Instances. This model of EC2 utilization allows customers to take advantage of unused capacity in the AWS EC2 public cloud.
Spot Instances are great for customers who need access to a large number of resources for a short period of time, such as for batch jobs or fault-tolerant applications.
Why spot Instances are cheaper?
Spot Instances are significantly cheaper than On-Demand Instances because they are based on unused EC2 capacity. When you select a Spot Instance, you specify the maximum price you want to pay and Amazon EC2 provisions it to you at the lowest available price.
Spot Instances are usually 10-30% of the On-Demand price in the same region, saving you up to 50% or more on your EC2 computing costs.
Spot Instances are an excellent solution for organizations with flexible Start/End times, particularly those applications that can be interrupted without loss of data, or applications that can quickly back up and restart with minimal disruption.
The cost advantage of Spot Instances can lead to significant cost savings for organizations, even after accounting for potential interruptions.
In addition to this cost advantage, Spot Instances offer a number of other benefits. For example, Spot Instances are not subject to restrictions that are inherent in On-Demand Instances, such as long-term purchasing or up-front payments.
This allows organizations to purchase only when they actually need the resources and avoid obligation-based purchases. Spot Instances also give organizations greater scalability and customizability than other options.
Overall, Spot Instances are an attractive option for businesses seeking greater flexibility, cost savings, and scalability in their cloud deployments.
How are spot prices calculated?
Spot prices are calculated based on the current market price of a commodity or currency. A spot price is the price at which traders are willing to buy or sell an asset or commodity at a given moment in time, and reflects investor sentiment, supply and demand dynamics, and economic data.
Spot prices change depending on various factors including the availability of the asset or commodity, currency exchange rates, and geopolitical events, among other things.
Spot prices for currencies and commodities are typically gathered from reliable sources such as stock exchanges, commodities exchanges, foreign exchange markets, and government sources. These spot prices can be used as a basis for forward or futures contracts, as well as for hedging against currency or commodity price fluctuations.
Generally speaking, spot prices are most widely used for commodities, where bids and asks from market participants are combined to determine an asset’s spot price.
Can spot Instances be more expensive than on-demand?
Yes, spot Instances can be more expensive than on-demand. Spot Instances are a type of computing instance offered by Amazon Web Services (AWS) in which the user gets to bid on unused EC2 capacity in the AWS cloud.
These instances are typically cheaper than on-demand instances, but may be subject to higher costs depending on the current market demand for EC2 capacity in a given region. When a user bids for an instance, AWS will attempt to fulfill their request at the specified price.
If the demand for EC2 capacity exceeds the current supply, then the user’s offer may be outbid and the spot prices for EC2 capacity may increase beyond the on-demand prices. In this case, the cost for the spot instance may be more than the on-demand option.
What is the difference between spot price and contract price?
Spot price is a current market price of a commodity, security or currency. It is the immediate price that the seller is willing to accept and the buyer is willing to pay for the good or asset. Spot price is affected by the supply and demand in the market, and can fluctuate based on the current market conditions.
Contract price, also known as a forward, futures, or futures contract, is a binding agreement between two parties to buy or sell goods, securities or currencies at a predetermined price on a future date.
This price is set at the time the contract is agreed upon, and may be higher or lower than the spot price at that time. Over time the spot price and contract price may converge or diverge, depending on the market conditions.
The contract price is determined by the attributes of the underlying asset, such as its volatility, and will have a built-in time premium due to the uncertainty of the future.

Amazon also offers a variety of cost-saving options, such as reserved instances and spot instances, which may help you reduce the overall cost for an EC2 instance.
In short, the exact cost of running an EC2 instance for a month will depend on the specific factors related to your usage. However, Amazon’s pricing calculator can help you estimate the total cost of running an EC2 instance, and there are also a number of cost saving options available that may help you further reduce the cost of running an EC2 instance.
Do EC2 instances cost money?
Yes, EC2 instances do cost money. Amazon EC2 instances are charged at an hourly rate, which is determined by the combination of instance type, Operating System (OS), the number of instances you are launching, and the AWS Region or Availability Zone you are running your instances in.
Additional costs may apply depending on the storage and network options you choose. The exact cost of an EC2 instance depends on the OS, instance type, and the number of hours that it is running. Some instance types are also eligible for a discounted rate if you set up a Reserved Instance for one or three years.
How is EC2 cost calculated?
Amazon EC2 cost calculation is based on the amount of time you use an instance and the size of the instance. You will be billed for the time that the instance is running, measured in hour-long increments.
The hourly rate depends on the instance type, AWS Region and operating system that you chose. Additional fees may be charged for any extra storage, data transfer, or additional services you use. In addition, there may be upfront and per-usage costs for the large selection of Amazon Machine Images (AMIs) available, which can help you get started quickly.
AMIs are pre-configured with all the components needed to run applications and services, so you can start using them as soon as they are launched.
You also have the option of purchasing reserved instances, which gives you a discounted hourly rate on EC2 instances in exchange for a commitment to use the instances for a one- or three-year term. Spot instances allow you to bid on leftover capacity and offers substantial price savings, but you must be prepared to lose your instance at any time if the Spot Price rises above your bid.
Amazon EC2 also has a simple, pay-as-you-go pricing model that allows you to launch and pay for usage of an On-Demand Instance in a short period of time.
Amazon EC2 also provides a wide variety of services and products that are billed separately from the base rate for an instance. Examples of additional charges include the cost for Elastic Load Balancing, Amazon Elastic Block Store (EBS), Amazon Relational Database Service (RDS), data transfer, network resources and premium support.
Depending on your specific use case, these services and products can add significantly to your EC2 costs. Lastly, Amazon EC2 offers discounts on EC2 instances if you are using AWS Free Tier, which provides services at no cost up to a certain amount of usage.
What is the disadvantage of Amazon EC2?
Amazon Elastic Compute Cloud (Amazon EC2) is a widely used cloud computing service from Amazon. It enables users to pay for virtual computing capacity, allowing them to quickly launch and scale applications in the cloud.
However, it is not without drawbacks, and the following are some of the disadvantages of using Amazon EC2:
1. Costs: Amazon EC2 can be costly in comparison to other cloud computing services. This is due to the fact that it requires upfront payment, hourly usage fees, and long-term contracts.
2. Security: As with any cloud computing service, Amazon EC2 can be prone to security risks. While Amazon does offer security measures in its service, users must be diligent with their own security setup.
3. Complexity: Although Amazon EC2 is relatively easy to use, it can be complex for more complex tasks. This is due to its wide range of features and the learning curve associated with it.
4. Limited Resources: Amazon EC2 provides access to a limited amount of computing resources. This could lead to incomplete data sets, or tasks taking longer than expected due to resource constraints.
5. Network Latency: Due to its distributed nature, Amazon EC2 can be prone to latency issues. This can be especially true for applications that require low latency for optimal performance.

Does an EC2 instance cost money when it is stopped?
Yes, an Amazon EC2 instance still costs money even when it is stopped. Amazon EC2 instances are billed based on the type of instance, the operating system, the duration the instance is running, and the number of instances used.
Even though the instances are not actively running, the customer is still responsible for paying for the instance storage. The cost associated with storage depends on the size of the instance and the storage, and the amount of storage used.
When an EC2 instance is stopped, the customer still must pay for the storage of the root volume and all of the attached EBS volumes. All data stored on EBS volumes associated with EC2 instances will remain and will be charged at the normal EBS rate.
The customer may opt for additional backup services separately.
