Cut Your AWS Costs By Using The RIGHT Pricing Model

The AWS pay-as-you-go pricing model is one of the main reasons or benefits for adopting it. pay-as-you-go “AWS pricing is comparable to how you pay for utilities like water or electricity,” Amazon states on their official website. You just pay for the services you use, and there are no hidden prices or termination penalties if you stop using them.” I’ll also highlight that AWS provides a pay-as-you-go payment option for over 70 of their services to further break this down. You’ll be charged for each one separately, depending on how long and how much you use them.

 

The AWS cost model provides a lot of benefits. As a manager, you may start working on new projects right away with no upfront costs for the infrastructure that supports your project or application, and you can scale up or down using just the resources your company needs at any given time. You won’t have to pay anything upfront this way. Paying as you go gives you greater flexibility since you can simply react to your business’s ever-changing demands. You won’t have to sign any long-term contracts or pay any license costs to utilize these services.

You may think about AWS Costs. We’ll show you how to make the most of this payment model and cut your costs. in this post.

What is AWS?

If you’re creating apps on the AWS cloud or just getting started with cloud computing, AWS certification is a great method to get an in-depth understanding of the platform’s core services. AWS presently provides 12 certifications, including Solutions Architect, Developer, and SysOps Administrator, that cover significant cloud roles. AWS Certification exams covering specific areas (such as machine learning, advanced networking, big data, and security) are also available at the associate and professional levels, as well as Cloud Practitioner, which is intended around AWS foundations for business jobs outside of IT.

Cut your AWS costs by using the RIGHT pricing model

Choosing the correct pricing models for paying for your Amazon EC2 instances is one of the greatest methods to decrease your AWS costs.

Amazon accepts four different payment methods:

• On-Demand
• Reserved instances
• Spot Instances 
• Dedicated Hosts

It’s vital to remember that AWS often introduces new instance types, thus we should always choose the most recent generation instance types since their pricing is much more optimized than previous generation instance types.

Let’s look at each payment option in more detail so you can pick the one that best fits your needs.

The On-demand

Amazon’s pay-as-you-go payment philosophy is embodied in the AWS on-demand pricing model. You don’t have to pay anything upfront, so you’re not committing to anything long-term. Amazon will bill you for computing capacity by the hour, and you may scale up or down your consumption based on your needs.

This pricing model is perfect for you if your organization requires flexibility if your application has specialized workloads with abrupt high or low workload bursts. Not only will you have a low-cost solution, but you’ll also be able to test and analyze your requirements before going all-in. This is best suited for businesses who are testing their solutions for the first time on Amazon EC2 instances.

Reserved instances 

Reserved Instances are an excellent method to save money because they are 30 percent less expensive than On-Demand instances. Because reserved instances are allocated to a certain Availability Zone, they allow capacity reservation, so you won’t have to worry about running out of capacity if additional instances are needed.

You might be curious as to why this pricing model is so much less expensive than On-Demand pricing. As the name implies, these are instances that you reserve in advance, which means you’ll be committing to a one-to-a three-year term in order to save money on computing.

In today’s world, three years is a very long time to invest in IT. Because so many variables may and will change over time resource demand, price, and so on impossible it’s to plan a comprehensive infrastructure for such a long time. As a result, I rarely advise signing a three-year deal.

While the main advantage of this pricing model is undoubtedly its cheaper cost, we shouldn’t forget that it also gives you peace of mind in knowing that your company has computer resources accessible anytime you need them. Of course, you must understand how your application works, as this is a great pricing strategy for apps that consume computational resources in a consistent and predictable manner.

Scheduled Reserved instances are for companies that need to execute their most critical tasks on a regular basis. Some of the use cases for these instances were defined by Amazon as follows:

• Every weekday afternoon, a bank or mutual fund executes Value at Risk computations.
• At the beginning of each month, a phone provider does a multi-day bill calculating run.
• On Monday, Wednesday, and Friday mornings, a trucking business optimizes routes and shipments.
• Every night, an animation studio creates a thorough, compute-intensive 3D rendering.

You may reserve EC2 computing capacity for one to three years with normally reserved instances, and as we noted previously, it’s always available.

Scheduled reserved instances to vary from regular reserved instances in that you can reserve them for up to a year, but only for preset repeating intervals using a daily, weekly, or monthly schedule. The greatest part is that it will often cost you 5-10% less than a similar On-Demand pricing model.

On an m4.large instance type running on the Linux operating system, we’ll compare on-demand and reserved instance pricing in the table below.

Instance class	Pricing model	1 hr/$	Upfront price(1-year term)	Monthly costs	Yearly costs
m4.large	On-Demand	0.1	0	73.2	878.4
m4.large	Reserved Instance – No Upfront	0.062	0	45.26	543.12
m4.large	Reserved Instance – Partial Upfront	0.059	258	21.54	516.48
m4.large	Reserved Instance – All Upfront	0.058	507	0	507

NOTE: The cost of an instance per hour varies per AWS location.

We can see from the table that the most optimum price approach is reserved AWS instances pricing upfront. It enables us to save more money by removing the need to pay for all of our costs upfront.

Spot instances

Spot Instances are interesting since they include bidding for unused EC2 computing resources, and they may save you up to 90% off the standard On-Demand fee.

Spot instances are only available for specialized use cases, such as urgent computing demands or programs that can only operate on extremely few computer resources. This is a fantastic approach to saving money since you can receive computer power for a fraction of the cost.

Dedicated host

Finally, the Dedicated Host price model is essentially a real EC2 server on which you may utilize your current server-bound software licenses. You may buy it as on-demand or reserved capacity, with reserved capacity being up to 70% less expensive.

Choosing the proper pricing model for your business use case or application is critical, as it will help you to dramatically reduce your AWS expenses, up to 90% in some circumstances.

Optimize to reduce costs

Using the Reserved Instances pricing model is one way to reduce AWS costs.

The most common AWS expense is computational resources, such as an EC2 instance. As a result, it’s vital to select the best instance for our operation, given the large price difference between instance families. Monitoring your resource utilization is critical since it allows you to ensure that your computing resources are not being utilized.

If you just require to compute resources for a limited period of time and don’t want to risk losing your data, spot instances can save you up to 90% over on-demand instances. This would be the scenario if you have an image resizing application that uses an EC2 instance for computing and S3 storage for image storage.

Another strategy to reduce your AWS costs is to evaluate them on a regular basis and terminate any resources that are no longer in use. Although your production instances must be able to auto-scale to meet demand, you may save up to 65 percent by shutting down your development or testing instances during off-peak hours or on weekends.

Any instances you have for training or demos should, of course, be terminated after these tasks are done.

Using AWS calculators

When you start utilizing many AWS services, it’s easy to lose track of the resources you’re using and how you’re using them.

While there are several methods to save money by optimizing and adjusting your AWS services and resources, these efforts will be futile unless you have a clear plan and an overview of your AWS usage. This leads us to the AWS Total Cost of Ownership (TCO) calculator, which is an excellent tool for estimating and tracking your costs. This is a simple program that allows you to calculate your cost savings and provide detailed reports.

As previously said, assuming and planning your resource usage is critical. You may use this dynamic calculator to predict your costs and savings based on the assumptions you set. Simply enter your existing hosting environment configuration, and the TCO calculator will offer a full cost comparison and expected savings if you migrate your applications to the AWS cloud.

How much does AWS cost?

When it comes to the AWS cloud, understanding pricing structures and how to best maximize expenditure optimization is critical for avoiding unpleasant surprises at the end of the month.

We don’t expect AWS to stop cutting the costs of its services and resources in the future. As a result, AWS services and resources will be more affordable than ever before.

Amazon Web Services (AWS) is the world’s largest cloud provider, with 175 services in infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS) (SaaS). On-demand pricing applies to all Amazon services, so you only pay for what you use. In this article, we showed you information about AWS cost so that you can optimize your AWS costs in some ways.
