AWS Billing and Pricing Flashcards

1
Q

AWS Pricing Model

A

AWS works on a pay as you go model in which you only pay for what you use, when you are using it.

If you turn off resources, you don’t pay for them (you may pay for consumed storage).

There are no upfront charges, and you stop paying for a service when you stop using it.

Aside from EC2 reserved instances you are not locked into long term contracts and can terminate whenever you choose to.

Volume discounts are available so the more you use a service the cheaper it gets (per unit used).

There are no termination fees.

Q

Data transfer charges

A

In most cases, there is no charge for inbound data transfer or for data transfer between other AWS services within the same region (there are some exceptions).

Outbound data transfer is aggregated across services and then charged at the outbound data transfer rate.

Q

On Demand EC2 Pricing Model

A

Means you pay for compute or database capacity with no long-term commitments of upfront payments.

You pay for the computer capacity per hour or per second (Linux only, and applies to On-Demand, Reserved and Spot instances).

Recommended for users who prefer low cost and flexibility without upfront payment or long-term commitments.

Good for applications with short-term, spiky, or unpredictable workloads that cannot be interrupted.

Q

Dedicated Hosts EC2 Pricing Model:

A

A dedicated host is an EC2 servers dedicated to a single customer.

Runs in your VPC.

Good for when you want to leverage existing server-bound software licenses such as Windows Server, SQL Server, and SUSE Linux Enterprise Server.

Also good for meeting compliance requirements.

Q

Dedicated Instances EC2 Pricing Model:

A

Dedicated Instances are Amazon EC2 instances that run in a VPC on hardware that’s dedicated to a single customer.

Dedicated instances are physically isolated at the host hardware level from instances that belong to other AWS accounts.

Dedicated instances may share hardware with other instances from the same AWS account that are not Dedicated instances.

Q

Spot Instances EC2 Pricing Model

A

Purchase spare computing capacity with no upfront commitment at discounted hourly rates.

Provides up to 90% off the On-Demand price.

Recommended for applications that have flexible start and end times, applications that are only feasible at very low compute prices, and users with urgent computing needs for a lot of additional capacity.

In the old model Spot instances were terminated because of higher competing bids, in the new model this does not happen, but instances still may be terminated (with a 2-minute warning) when EC2 needs the capacity back – note: the exam may not be updated to reflect this yet.

Q

Reservations Pricing Model:

A

Reserved instances provide significant discounts, up to 75% compared to On-Demand pricing, by paying for capacity ahead of time.
Provide a capacity reservation when applied to a specific Availability Zone.
Good for applications that have predictable usage, that need reserved capacity, and for customers who can commit to a 1 or 3-year term.

Reservation options include no upfront, partial upfront and all upfront.

Reservation terms are 1 or 3 years.

34
Q

Consolidated billing includes:

A

Paying Account – independent and cannot access resources of other accounts.

Linked Accounts – all linked accounts are independent.

35
Q

Consolidated billing has the following benefits:

A

One bill – You get one bill for multiple accounts.

Easy tracking – You can track the charges across multiple accounts and download the combined cost and usage data.

Combined usage – You can combine the usage across all accounts in the organization to share the volume pricing discounts and Reserved Instance discounts. This can result in a lower charge for your project, department, or company than with individual standalone accounts.

No extra fee – Consolidated billing is offered at no additional cost.

36
Q

Other Consolidated Billing Facts

A

Limit of 20 linked accounts (by default).

One bill for multiple AWS accounts.
