问题 AWS rookie here. I created a few EC2 instances under my AWS account and reused the same Key Pair for all of them. I believe (IIRC) that I had generated the Key Pair from inside AWS, but that could be wrong. Over this past weekend I sold my old laptop (after completely wiping the hard disk) and got a new one. I'm just remembering now ( :facepalm ) that I forgot to copy all my SSH private keys to a flash drive and that I no longer have them. All I want/need to do is to SSH into my EC2 instances

问题 Can we enforce tagging in AWS while creating a resource so that the resource will not be created unless a tag is given manually to the resource while creating? 回答1: Short Answer: Cannot enforce through policies for All resources.

问题 We are evaluating SNS for our messaging requirements to integrate multiple applications. we have a single producer that publishes messages to multiple topics on SNS. Each topic has 2-5 subscribers. In event of subscriber failures (down for maintenance) I have a few questions on the recommended strategy of using SQS queues per consumer Is it possible to configure SNS to push to SQS only in event of failure in delivering the message to a subscriber? Dumping all the messages in SQS queue creates

问题 I am spinning up an EMR in AWS. The difficulty arises when using Jupyter to import associated Python modules. I have a shell script that executes when the EMR starts and imports Python modules. The notebook is set to run using the PySpark Kernel. I believe the problem is that the Jupyter notebook is not pointed to the correct Python in EMR. The methods I have used to set the notebook to the correct version do not seem to work. I have set the following configurations. I have tried changing
