As i observe on the services quota panel that the applied quota value of AWS lambda , is much lower then the aws default value. How can I increase this value?
I cannot find proper guidelines of how to increase the applied quota value as much of the resource related to it is about how to increase the default quota.
Same process, use the Request quota increase function in the Service Quota's console. The Lambda Quotas documentation gives some insight, that there are specific limits placed on new AWS Accounts, which get automatically raised over time.
The fact they don't explain this in the Service Quota's console isn't very user friendly.

I was trying to estimate AWS lambda using AWS pricing calculator, but I am confused.
If I estimate Provisioned concurrency section than is Service settings section mandatory to estimate ?
If your Lambda functions exceed the provisioned concurrency, the excess executions will be charged at the normal rate (ie. the rates shown in the Service settings section). You don't need estimations in both sections if you plan to keep everything within your provisioned concurrency limits. However if you only provision at a certain baseline and your function is expected to scale beyond that, your estimate should include the excess executions in the Service settings section.
Does anywhere officially or unofficially document what the true maximums are for all AWS quotas?
I am new to AWS, and am trying to figure out the maximum values for certain quotas.
For example, the default value for S3 Access Points supports a maximum of 1000 per account.
but in the AWS quota console it says it is Adjustable, and the docs suggest I can request a quota increase.
You can create a maximum of 1,000 access points per AWS account per Region. If you need more than 1,000 access points for a single account in a single Region, you can request a service quota increase. For more information about service quotas and requesting an increase, see AWS Service Quotas in the AWS General Reference.
I'd like to know what the true maximums are across the board for IAM and S3 resources, to ease design of features I'm working on, without having to do a request to increase resources I may not actually use, if appropriate resource limits can't be requested.
After discussing with AWS support, some quota changes aren't reflected in this console at this time (e.g dynamoDb quota changes)
Haven't tried it, but possibly using aws-limit-checker may show the real limits
I am currently signed up to the free tier of AWS. I am enjoying experimenting with various services including those not affording by said free tier. Can AWS's enhanced budgets be used to stop services like EC2 instances if I accidentally spend too much? Or do they merely act as alerts?
This is available for EC2, I don't think it is available for all of the AWS resources.

Hope it helps.
There are several posts which looks it from different perspectives, such as this and this.
Having a cost cap might be a crucial requirement based on the usage, especially when considering how complex it is to set the things up properly and keeping everything secure on the cloud for an average user. At least we can expect to have a feature to switch on/off a cost-cap service, so a user can decide their own scenario easily.
Closest solution that I found is here:
Serverless Automated Cost Controls
https://aws.amazon.com/blogs/compute/serverless-automated-cost-controls-part1
It explains how to trigger AWS Lambda function to change IAM permission from EC2FullAccess to EC2ReadOnly when the budget exceeds the limit.
There is no built-in way to terminate services based on budgets or billing alarms.
You can get notified automatically, but it is then up to you to determine how to handle it.
Would you really want AWS automatically terminating your production infrastructure because you went $1 over your estimated monthly spending?
Edit: There is now a way to monitor and alert on free tier usage, and when your predicted usage will exceed the free tier. See here for details. You could probably come up with a way to terminate infrastructure based on an alert using SNS & lambda.
Edit 2: In Oct. 2020, AWS released Budget Actions - the ability to trigger an action when a budget thresholds are reached. This should give you the ability to automate a response - you can shut down servers, change IAM permissions to prevent additional infrastructure from being created, etc.
Recently, Amazon has given "budget action" to carry out actions like stop services automatically if the budget has exceeded.

what is the maximum number of rules for cloud watch I can create on my AWS account. I might have a lot of different rules that will invoke lambda function on schedule. Is it unlimited?
The basic limits are documented at http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_limits.html - currently 50 rules per account.
If you need more, reach out through your AWS contact and these can be expanded.
This is no longer 50 and has been increased to 100 per region per account.
As per this link:
https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/cloudwatch_limits_cwe.html
And as mentioned by johnny: this can be increased further on request (if amazon approves the request).
After talking to AWS cloud watch team I found out that the rule limit can be increased as per your need.
If you're willing to use a non-AWS service, then you might check out Microsoft Azure. Azure offers a great job scheduler that doesn't pose any limits. You could use this service to invoke your lambda functions.
Everything was working yesterday and I'm simply still testing so my capacity shouldn't be high to begin with but I keep receiving these errors today:
{
Message = "We currently do not have sufficient capacity in the region you requested. Our system will be working on provisioning
additional capacity. You can avoid getting this error by temporarily
reducing your request rate.";
Type =Service;
}
What is this error message and should I be concerned that something like this would happen when I go into production? This is a serious error because my users are mandated to login using calls to api gateway (utilizing aws lambda).
This kind of error should not last long as it will immediately trigger AWS provision request.
If you concern about your api gateway availbility, consider to create redundant lambda function on other regions and switch whenever this error occurs. However calling lambda from a remote region can introduce long latency.
Another suggestion is, please review the aws limits for API gateway and Lambda services in your account. If your requests do exceed the limits, raise ticket to aws to extend it.
Amazon API Gateway Limits
Resource Default Limit
Maximum APIs per AWS account 60
Maximum resources per API 300
Maximum labels per API 10
Increase the limits is free service in aws.
Refer: Amazon API Gateway Limits
AWS Lambda posted an event on the service health dashboard, so please follow this for further details on that specific issue.
Unfortunately, if you want to return a custom code when Lambda errors in this way you would have to write a mapping template and attach it to every integration response where you used a Lambda integration.
We recognize that this is suboptimal and is work most customers would prefer API Gateway just handle for them. With that in mind, we already have a high priority item on our backlog to make it easier to pass through the status codes from the Lambda integration. I cannot, however, commit to a timeframe as to when this would be available.
