AWS: DB Instance quota exceeded - amazon-web-services

During CloudFormation stack-creation I get a CREATE_FAILED error for Aurora with reason DB Instance quota exceeded.
I assume it means there are too many DB instances running (I'm on a company account with a federated login, and not the only one creating stacks and launching instances).
How do I fix it? Do need to delete some running instances? Also, how do I find out what the allowed quota is?

Limits in Amazon RDS shows a limit of 40 Amazon RDS DB Instances per Region.
You can contact AWS Customer Service to request a limit increase. Here's the Support screen:

AWS Free Tier Usage Limit and delete EC2 Instances

I received aws billing email notification that "exceeded 85% of the usage limit for one or more AWS Free Tier-eligible services". When I check EC2 instance are running zero?
Can someone explain where to check running instances and if there is no any running instances why I received email?

AWS EC2 limit error while updating EC2 instance of Elastic Beanstalk

While updating EC2 instance of Elastic Beanstalk the following error message appeared. But for my other account the following error, not observed:
Updating Auto Scaling group named: awseb-e-tiknsbmh4d-stack-AWSEBAutoScalingGroup-R3UXFI8KMCSN failed Reason: You have requested more instances (1) than your current instance limit of 0 allows for the specified instance type
Is it account base specific? And what is the best way to fix it?
Yes, there are limits which are account-specific.
You can check your EC2 quotas using the AWS Quota Service. [1]
You can view the EC2 quotas which apply for the account you are currently signed in by visiting the following URL: https://eu-central-1.console.aws.amazon.com/servicequotas/home?region=REGION#!/services/ec2/quotas by replacing REGION with your region identifier, e.g. us-east-1.
If the quota is marked as adjustable, you can request an increase via this service.

[1] https://docs.aws.amazon.com/servicequotas/latest/userguide/intro.html
This message is related to Amazon EC2. Even though the instance was launched by Elastic Beanstalk, the limit is related to the number of concurrent Amazon E2 instances permitted.
There are two types of limits:
Total number of concurrent instances (default: 20)
Number of concurrent instances per instance type (default varies)
You can view these limits in the Limits section of the Amazon EC2 management console. You can also request an increase in the limits.
The limits are "per account, per region".

AWS EC2 - Can we restrict(decrease) the max storage volume limit allocated per region in AWS?

Scenario:
- t2.micro instances : Amazon Linux AMI
- Number of instances : 15
- Volumes
root Volume : 8GiB
Additional EBS Volume : 10000 GiB
When i am trying to launch the Ec2 instances, i am getting following error:
Launch Failed You have exceeded your maximum gp2 storage limit of 100 TiB in this region. Please contact AWS Support to request an Elastic
Block Store service limit increase. Hide launch log
Creating security groups Successful (sg-0567946d12185cda5) Authorizing inbound rules Successful
Initiating launches Failure Retry
I know why this error came up. In the AWS Docs its clearly mentioned that the
Amazon Elastic Block Store (Amazon EBS) Limits: Total volume storage
of General Purpose SSD (gp2) volumes - Defailt Limit is 100 TiB
For increasing limit as mentioned in error message i have to contact AWS.
Is there any way by which i can decrease this limit?
In the Amazon EC2 management console, click Limits in the left navigation pane.
Scroll down to EBS Limits to view the current limits.
You can request an increase/decrease of the limits by clicking Request limit increase.

Master Instance Group: Exceeded EC2 Instance Quota

I am getting this error Master Instance Group: Exceeded EC2 Instance Quota, when I create a new cluster on Amazon EMR with 1 Master node only or 1 Master and 2 Core nodes. However, there are no EC2 instances running on my account.
What should I do? I raised a ticket, asking if I can get a quicker solution here.
In your case I think you are trying to access a new region or new instance type, AWS sometimes does that when you are in free tier, they allow access to 2-3 regions or free instance types only. Then you have to request access from AWS by raising a case.
But in Normal scenario, this is what happens:
You may face an error like Exceeded EC2 Instance Quota while you are trying to spin up new instances either standalone or in cluster.
This error is caused because you have hit the limit on number of instances allowed in your AWS account.
This limit is region and instance size specific. To get rid of this error you will have to request Amazon to increase the EC2 instance limit.
Requesting a limit increase is simple. Below are the steps:
Most service limit increases can be requested through the AWS Support Center by choosing Create Case and then choosing Service Limit Increase.
Most service limits are specific to a particular AWS Region, so be sure to submit a request for each Region you plan to use. Many services support requesting multiple limit increases for the same service through one support case. After creating your first request, choose Add another request and then choose a new limit type or Region.

How can we provision number of core instances in AWS Data Pipeline job

Requirement: Restore DynamoDB table from S3 Backup location.
We created Data Pipeline job, and then edit Resources section in Architect Wizard.
We placed 20 instances under Core Instance count, but after the Data Pipeline job activation, EMR Cluster was created with only one master and one core instance.
Could you please suggest us, how to increase the number of cores under Resources section
You might be hitting the total EC2 resource limit. You can have only 20 On-Demand EC2 instances running unless you have requested a limit raise.
Datapipeline acknowledges this limit. You have to increase the EC2 Ondemand resource limit using the link below.
A similar scenario from the docs:
If you configure AWS Data Pipeline to automatically create a 20-node
Amazon EMR cluster to process data and your AWS account has an EC2
instance limit set to 20, you may inadvertently exhaust your available
backfill resources. As a result, consider these resource restrictions
in your design or increase your account limits accordingly.
If you require additional capacity, you can use the Amazon Web
Services Support Center request form to increase your capacity.
