They are reserved for applications with flexible start and end periods, for users with urgent requirements for a large amount of additional computing capacity, and for static and fault-tolerant applications. Please note, however, that Spot instances are not suitable for all uses. Take advantage of discounts of up to 90% off on-demand rates. The advantage of Spot instances is the discount percentages that cannot be compared with other types of billing. It's a kind of recycling of the "compute" available. Spot EC2 instances allow AWS users to take advantage of unused computing power in the AWS Cloud. If you would like to know more about how to introduce Saving Plans into your Cloud strategy, we have prepared some tips on this article. Discounts are equivalent and allow you to save up to 72% compared to on-demand instances. Like reserved instances, Saving Plans allow you to reserve computing power in advance, for the same duration: 1 or 3 years. Concretely, if you are currently using Reserved Instances, we advise you to migrate gradually to Saving Plans. The most? Additional flexibility with respect to families of instances, size, SO or region. In concrete terms, Saving Plans are similar to improved instance reservation. Like reserved instances, Saving Plans are an effective way to anticipate your Cloud budget and limit the uncertainty associated with too much variability in spending. The benefits are essentially to project over time, to establish a more accurate budget and to reduce the impact of variability in expenses on your AWS bill. Reserved EC2 instances are suitable for very linear applications and for users requiring true stability over the medium or long term. The commitment is for 1 or 3 years and you benefit from a rate of up to -75% off the initial price (in theory, of course). As we have already presented in this article, the reservation of instances allows you to anticipate your consumption of Cloud resources and to benefit from very interesting discounts on your billing. Reserving AWS EC2 instances is a well-known practice among AWS users. On-demand billing is suitable for development teams looking for real flexibility, for applications generating traffic peaks that are difficult to anticipate or for workloads that cannot be interrupted by chance. You can opt for instances that are more computationally oriented, or more storage oriented, machine learning, etc. The (very) wide range of instances proposed allows to cover an almost infinite scope of application. The main variability criteria: the operating system, the technical configuration of the instance (number of vCPUs, GB of RAM, type of storage.) and the deployment region. It would be really simple if pricing was not so variable. This is the B-A-BA of AWS pricing: you only pay for what you consume, in real time. Let's try to get a clearer picture.ĮC2 instances are available in 4 major AWS billing models: Paradoxically, Amazon EC2 pricing is much less fluid than AWS promises. Amazon EC2 is a virtual machine service that enables businesses to benefit from secure and flexible computing power, all with the simplicity and immediacy of Cloud services. To allow you to navigate more simply, here is the summary of this article:ħ - Free tools from the compute AWS rangeĪmazon EC2 is one of the flagship products in the AWS offering. We will discuss the products one after the other to give you a 360° view of AWS's tariff specificities. Here is a complete article to help you better understand the pricing of compute AWS products. The performance of AWS Cloud services is well established: Amazon provides high quality products that meet the needs of most businesses, regardless of industry or size.Īs is often the case, what is of concern in Cloud services is the vagueness surrounding the billing model. The computing power (compute) is the basis of the Cloud.
