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.

While launching 2nd instance getting below error
you have requested more vcpu capacity than your current vcpu limit of 1 allows for the instance bucket that the specified instance type belongs to. please visit http://aws.amazon.com/contact-us/ec2-request to request an adjustment to this limit.
First, please note that the AWS Free Tier is a billing discount. It does not impact your ability to use any services. If the resources you use are within the limits imposed by the AWS Free Tier, you simply won't be charged for those resources. Thus, the AWS Free tier is not the cause of this error.
From On-Demand Instances - Amazon Elastic Compute Cloud:
There is a limit on the number of running On-Demand Instances per AWS account per Region. On-Demand Instance limits are managed in terms of the number of virtual central processing units (vCPUs) that your running On-Demand Instances are using, regardless of the instance type.
You did not tell us what Instance Type you are running, or attempted to run, but it sounds like you have exceeded this vCPU limit. This is more likely to happen with large or expensive instance types, or instance types that use GPU resources. You can view the limits in the Amazon EC2 management console by clicking Limits and then searching for vCPU.
If this is impacting your use of AWS, you can request an increase to these default limits.
See: Calculate a vCPU limit increase request for an Amazon EC2 On-Demand Instance
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.

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".
This is from the amazon ec2 FAQ :
Q: How quickly can I scale my capacity both up and down?
Amazon EC2 provides a truly elastic computing environment. Amazon EC2 enables you to increase or decrease capacity within minutes, not hours or days. You can commission one, hundreds or even thousands of server instances simultaneously. When you need more instances, you simply call RunInstances, and Amazon EC2 will typically set up your new instances in a matter of minutes. Of course, because this is all controlled with web service APIs, your application can automatically scale itself up and down depending on its needs.
Now again as per the same FAQ, I am only allowed to launch 20 instances per region. They said, I have to fill in a request form if I need more than 20 instances. So, in effect, I cant spin up more than 20 programmatically ?
What am I missing here ? how can we launch 100 instances let alone thousands. Sorry if this is the wrong place for such a question.
You cannot launch instances beyond the instance limit. You need to make a request to increase the instance limit. This is a safety feature so that:
A wild loop in your SDK/API script does not launch instances continuously
A malicious user does not launch a large number of instances
A hacker gets access to your account and launches a large number of instances
An incorrectly configured autoscaling group launches huge number of instances
If you require more than your instance limit, you need to submit a request to AWS. See: Amazon EC2 Service Limits. AWS will review your request and approve it.
You are missing the fact that limit increase requests are very easy to make and are almost always granted with no questions asked within a day or two.
To request a limit increase:
Open the AWS Support Center page, sign in if necessary, and choose Create Case.
For Regarding, choose Service Limit Increase.
Complete Limit Type, Use Case Description, and Contact method. If this request is urgent, choose Phone as the method of contact instead of Web.
Choose Submit.
AWS faqs provides a clear answer
You are limited to running up to a total of 20 On-Demand instances across the instance family, purchasing 20 Reserved Instances, and requesting Spot Instances per your dynamic Spot limit per region. New AWS accounts may start with limits that are lower than the limits described here. Certain instance types are further limited per region as follows
For Spot instance limits AWS states
The usual Amazon EC2 limits apply to instances launched by a Spot Fleet, such as Spot request price limits, instance limits, and volume limits. In addition, the following limits apply:
The number of active Spot Fleets per region: 1,000
The number of launch specifications per fleet: 50
The size of the user data in a launch specification: 16 KB
The target capacity per Spot Fleet: 3,000
The target capacity across all Spot Fleets in a region: 5,000
A Spot Fleet request can't span regions.
A Spot Fleet request can't span different subnets from the same Availability Zone.
These limits protect you from a hacker attack, stolen API keys, ETC. If you want to increase these limits, you need to send a form to AWS support team: AWS Support Center
I need to launch a Amazon EC2 instance, in particular a GPU accelerated one. I already tried with free tiers using t2.micro
instances and everything is fine. When I try to select a non free one such as g2.2xlarge I get this error
Launch Failed
You have requested more instances (1) than your current instance limit of 0 allows for the specified instance type. Please visit http://aws.amazon.com/contact-us/ec2-request to request an adjustment to this limit.
(Service: AmazonEC2; Status Code: 400; Error Code: InstanceLimitExceeded; Request ID: 4ebf71ee-e927-42c2-8377-697a3a6cfd4b)
I'm trying to use a machine with Deep Learning AMI Ubuntu Version (but I also tried with other ones). I get this error even if I'm not running any other instance and according to the documentation the limit for these one is 5 at a time.
I have also tried to select different regions (my country is not among the choices) but it doesn't seem to change the result.
My only guess about this issue is that somehow I'm registered as a free user and I'm not allowed to use the priced services, but I'm not so sure about that.
Edit: I have a credit card on file on Amazon (they require it to register) and they should charge me from that.
Am I missing something?
Every amazon account has limits - even big corporate accounts. These limitations are set by Amazon, but you can request a limit increase. You can find your limits by clicking the Limits link in the top left hand side inside the EC2 Dashboard.
For example, if you have a t2.micro already running and you try to launch a g2.xlarge that had a limit of 1, you would not be able to since your limit of 1 has already been hit with your t2.micro that is running.

In amazon aws how many m1.small spot request can i create in one region by default
when i see in Instances limit it shows me some thing like
Spot Instance requests default Request limit increase
but currently i am running 36 m1.small
and it gives me an error while creating new spot request
MaxSpotInstanceCountExceeded
so my question is how many spot request can i make of one particular type (eg.m1.small or m1.large)
or how does amazon aws calculate MaxSpotInstanceCountExceeded
MaxSpotInstanceCount is the hard limit of on number of spot instances that you can launch irrespective of their type. the default is 5. However, in your case it seems to be 36.
You can request AWS to increase the limit by filling out this form: https://aws.amazon.com/support/createCase?type=service_limit_increase&serviceLimitIncreaseType=ec2-instances
For any other doubts, please reach out to their support: https://aws.amazon.com/support
