Questions tagged with Reserved Instances

Hello. We got reserved nodes that will expire in a few days. I don't want to prolong them because we changed the instance type from `ds` to `ra`. I'm asking this question because I want to be 100% sure that there will be **no** payment, right now I've got the following: ``` Reserved nodes: 4 Reserved nodes used: 0 Reserved nodes available: 4 ```

I've already looked for it in any email and Q&A/Faq all over the AWS environment but I can't find if it is possible to use my AWS Credit to purchase a Reserved Instances and/or a Reserved Amazon RDS. Does anybody know if I buy one, the billing system will use this credit or if it's not intended for this purpose? Thank you very much in advance to everybody who will help me!

We are a startup based in India and are using AWS for our entire tech stack from a long time. Recently, our EC2 reserved instances expired and we upgraded to Savings plan for them. Our credit card is declining the partial payment amount because it is high for a lump sum amount. The plan already got rejected once due to this. We have applied again. Can we have the total amount divided into smaller parts and get charged via multiple cards? Do we have any other mode of payment like payment via link, bank transfer, cheque etc. to complete this process asap. We are getting charged on the on-demand pricing that is costing us a lot. Any help is highly appreciated.

We have a db.m5.large RDS instance for which we have a reserved instance that is going to expire after 4 months. We upgraded our instance to db.m5.xlarge recently due to high CPU usage. Currently, our new instance is running on On-demand pricing, while our reserved instance is getting wasted. Is my understanding correct? Can we upgrade our reserved instance to this level also?

I have an "m1.small" 3-year reserved instances which will be expired on July 31, 2023. The EC2-classic will be retired after Aug. 2022, so I have to migrate my EC2 classic instance to VPC by the deadline. Unfortunately, It looks like the "m1.small" instance type is no more available in the VPC. If I'd like to migrate my EC2 instance to "t3.small", how do I modify my "m1.small" reserved instances to "t3.small"? PS: I tried to modify the reserved instances, but no "t3.small" option in the available list.

I created a new AWS account in my AWS Organization. When I try to create a reserved instance in the account I get the following error: "Error: Your current quota does not allow you to purchase the required number of reserved instances (Status Code: 400; Error Code: ReservedInstancesLimitExceeded; Request ID: 52e35efd-89aa-44ef-9794-026b1176d21b)" Reserved instance details: * Region = us-east-2 * Instance type = g4dn.2xlarge * Offering = standard * Quantity = 1 * Payment terms = All Upfront It's a new account so I do not have any existing instances in the account in any region. When I go to limits, it shows that my "Reserved Instances" limit is 20. I clearly have the limit available for reserved instances, so why am I getting this error?

Hello there, We recently apply reserved instance no upfront, then the next day our billing shows double EC2 bills, can you clarify this ? 1. On Demand 2. Reserve Instance Same specs. Please advise

Hi Guys, does anyone know if it's possible to share RI/SavingPlans between different AWS Organizations? (someone told me that it's possible but I can't get documentation on that) - I am pretty sure that is not possible but I want to be sure. Thanks in advance! :)

Does Databricks give customers the option to choose reserved instances or are there any barriers to savings plan ? Does EMR provide reserved instances?

could i apply the same RI at r5.xlarge.tpc2.mem2x and r5.xlarge? In case of RDSoralce(BYOL-SE2)

I'm having a hard time figuring out if reserved instance costs appear in Cost Explorer in the account they were purchased or in the account where they were applied. For example I have an Management Account and two sub accounts B and C. If the reservations I bought in the Management Account are applied to EC2 instances in account B are they billed to the Management Account or B when I break out costs by linked accounts? Put another way. Do reserved instances get applied to the Management Account as a lump sum at the beginning of the month or are they reflected as EC2 costs (billed at a lower rate) accrued inside of the linked account? When I look at my cost explorer by linked account do I see all the costs generated in that account including the reserved instances that were consumed by the account or are reserved instances billed in the account they were purchased in?

hello everyone, if i bough a regional reserved instance (which gives no capacity reservation in any availability zones within the region) and i created a reservation over a specific AZ match the same attributes of the regional reserved instance and then created the instance in that AZ that match both regional reservation and AZ capacity reservation attributes , do i get charged on demand (no discount) because of unused reservation in the AZ if the regional reserved instance is stopped ?

Hi, Does anyone know how to cancel a reserved ec2 instance? I purchased a wrong ec2 instance around 6 months ago, now it charges me every month... but I'm not using it

Are there any plans to permit the reservation of t4g-class instance types on RDS? Currently, t4g is omitted from the reservation pricing page, at least for MySQL in us-east-1: https://aws.amazon.com/rds/mysql/pricing/?pg=pr&loc=2 Both the AWS web console and direct usage of the API show no offerings for db.t4g: ``` $ aws --output=json rds describe-reserved-db-instances-offerings --db-instance-class=db.t4g.medium { "ReservedDBInstancesOfferings": [] } ```

A customer with 10 RDS (Aurora MySQL) instances (T2.small, R4.large). If they buy T3 reserved instances (RI): - can they use these credits for any T type instance from any size? ex, to a T2.small (or later) if you initiate a new generation under the same T family (e.g. T4) - could they use half of these RI for T3.large? - is there a mapping table? ex. "T3.large equals 2+ T2.small". - are RI interchangeable with different types? ex. buying a T3.small RI counts for a R4.large Thanks

I was getting two very different sets of numbers in Cost Explorer between the Cost Explorer details linked from the EC2 Reserved Instances Recommendations, and doing my own filtering based on known instance types in tags in another window (costs and hours in my window were about double). The filter that made them match up turned out to be Tenancy, where the RI page was specifically specifying Shared Tenancy, but I had no filter on, which was including both Shared and No Tenancy. What does No Tenancy mean? I can find info on Dedicated, Shared and Default, but not "No Tenancy". Note, there are no dedicated hosts being used.

- How could I find out when an RDS instance would go out of support? - What happens if an RI is purchased for an instance which is about to retire? Does that mean the Db needs to be replaced when the instance is retired ?

A customer is interested in RDS RIs, but confused with our description of what is fixed for RIs. According to [this page][1] On one hand "Region, DB Engine, DB Instance Class, Deployment Type and term length must be chosen at purchase, and cannot be changed later.". As I understand, deployment type is Single or Multi-AZ, so it can't be changed after the purchase. But on the other hand, "The RI discounted rate will also apply to usage to both Single-AZ and Multi-AZ configurations for the same database engine and instance family. For example, let’s say you purchased a db.r3.large PostgreSQL Single-AZ RI in EU (Frankfurt). The discounted rate of this RI can automatically apply to 50% of the usage of a db.r3.large PostgreSQL Multi-AZ instance in the same region." Does it mean that I can change deployment type (Single -> Multi) for the reserved instance, but in this case the only 50% of price will be covered by RI purchase?

Please confirm, If I do a 1 year RI for an account, If I stop the service in between of the month, same RI benefit can be given to another Account . For e.g I have 2 account under ABCD Root account. Account 1 Account 2 If I reserve one VM for year under Account 1, and If I delete the VM in middle of the year, can I pass on RI benefit to any other VM under Account 2.

A customer wants to move away from Zonal RI's and go to Compute Savings Plans; However, they would still like the ability to reserve capacity as they did with Zonal RI's. What's the recommended best practice here?

1. Customers can purchase dedicated reserved capacity for EC2 which means the instance is guaranteed to be available, but I do not think you can do that for RDS. Can you please confirm? DB engine is SQL Server. 2. Does buying a RDS reserved instance help with instance availability as customers with RIs get priority over on demand.

"If you can predict your need for Amazon DynamoDB read-and-write throughput, reserved capacity offers significant savings over the normal price of DynamoDB provisioned throughput capacity. You pay a one-time upfront fee and commit to paying for a minimum usage level at specific hourly rates for the duration of the reserved capacity term. Any throughput you provision in excess of your reserved capacity is billed at standard rates for provisioned throughput." Is it possible to reserve capacity for DynamoDB **without** upfront commitment, like we can do in RI's with no upfront payment? Taking into account the text above it is not possible, but would like to confirm it.

When a customer has consolidated billing, if a reserved instance is not used in the account where it was purchased, it will be used in the best suitable linked account that maps with the same characteristics. Is there a way to trace that account/instance-id where it was used. It is challenging to know who is taking the unused reserved instances for internal budgeting.

Hi, Is it possible to use scheduled reserved instances for Dedicated Hosts? I do not see this listed as an option, however I wanted to double check before informing my customer: https://aws.amazon.com/ec2/dedicated-hosts/pricing/
