Billing & Pricing

Price Models

Capex (Capital Expenses)

• Expenses that are paid in advance.

• It is a Fixed Cost, non recoverable.

Opex (Operational Expenses)

• Pay for what you use.

  • Like public services: water, gas, electricity.

Price Fundaments

There are 3 fundamental cost factors in AWS:

• Computing (More processing power = More expensive)

• Storage (More storage = Less cost rates)

• Bandwidth

Price Policies

• Pay according to use.

• Pay less when reserving.

  • Like when you reserve for 1 or 3 years.

• Pay even less by unit when using more.

  • Like storage rates going down the more GB you use.

• Pay event less with AWS growth.

Price models vary depending on the service so:

• Always optimize costs.

  • IT must not be treated as Periodic Capital Investment anymore, BUT as efficient use of resources.

• Maximize the power of flexibility.

  • AWS has independent ans transparent costs, so you can choose what you need and not waste.

  • AWS does not require long term contracts or minimum adhesion time, except when reserving.

  • You only pay if services are executing and for the time that they executed.

• Use the right price model for the work to be done.

  • AWS offers several price models like:

    • On Demand.

    • Dedicated Instances.

    • Spot Instances. (Supply and Demand)

    • Reserved.

EC2 Pricing

Some attributes that can change the price

• Hours used by the server.

• Type of instance.

• Price model.

• Number of instances.

• Load Balancing.

• Detailed monitoring. (Increases prices)

• Auto Scaling.

• Elastic IP Addresses.

• OS and packages.

Pricing models for EC2

On Demand

• Allow you to pay a fixed rate by (hour/seconds) of execution.

• No fidelity terms.

• AWS may not garantee capacity.

  • Meaning that Reserved instances have higher priority.

Reserved

• Reserve capacity for a significant discount in the (hour/second) rate.

  • Must have fidelity over 1 or 3 years.

  • The more you pay up front, the more discount you can get.

• You are stuck with the hardware that you reserved. (It is possible to change with Conversible Reserves)

• AWS can garantee your hired capacity, but no more than that.

  • And if you go over your hired capacity, the overload will be charged as On-Demand.

Types of Reserved

• Default Reserve:

  • Offers up to 75% discount over on-demand instances. The longer the contratct the higher the discount.

• Conversible Reserve (RI):

  • Up to 54% discount over capacity on-demand to change the RI attributes, as long as the change results on creating reserved instances of equal or superior value.

  • Like if you have to get more powerful hardware.

• Schedule Reserve:

  • Are available to be lauched within the specified date ranges that were reserved.

  • This option combines capacity reserve with recurrent predictable programming that requires a fraction of a (day, week or month).

Spot

• AWS will let you bid on the value of non used instances.

  • Meaning that you may pay as much as you would like if available.

• These have the lowest prices available.

• But, AWS does not garantee capacity AND may even terminate your instances at any time if needed.

  • For this reason it is recommended for stateless work that can be done on flexible timeframes.

Dedicated

• Will provide you with dedicated server hardware.

• The more expensive options.

• For Enterprise solutions that:

  • Have BYOL (Bring your Own License).

  • Critical need for capacity. AWS won't touch your instances or prevent you from running them.

Lambda Pricing

• By requisitions:

  • Free Tier: 1 million requisitions by month.

  • $0.20 for 1 million requisitions.

• By duration:

  • 400.000 GB by second by month for free, and up to 3.2 millions of seconds of execution time.

  • $0.00001667 for each GB by second used.

Additional costs may be charged if your lambda functions use other services or transfer data.

EBS Pricing

• Volume (by GB).

• Snapshots (by GB).

• Data transfer.

S3 Pricing

• Storage.

• Requisitions.

• Types of storage class.

• Data transfer.

• Transfer acceleration.

• Replication between Regions.

RDS Pricing

• Server turn-on time.

• Database caracteristics.

• Database types.

• Number of instances.

• Provisioned storage.

• Additional storage.

• Requisitions.

• Data transfer.

Cloudfront Pricing

• Traffic distribution.

• Requests.

• Data output.

Free Services that AWS provides

• Amazon VPC.

• Elastic Beanstalk.

• CloudFormation.

• IAM.

• Auto Scaling.

• OpsWorks.

• Consolidated Billing.

These service may be free, BUT some of them uses or creates other services that can be billed.

For instance, Elastic Beanstalk may create EC2 instances that will be billed.
