Hi, When I open my account today I saw that Amazon deleted my ec2 instance but everything else like my security groups, elastic ip addresses and keys etc, all of the configurations were there. When I ask my lost ec2 instance to online support, the explanation by the support team was "resources can be deleted by amazon during suspension period". My 1 month age account was put on hold since 9 September 2022 because of wrong address information. I was asked for documents related to account owner, and payment method so I provided all. The verification process took 7 days and I could verify myself at the and and I got my account reactivated today. Well, I'm not aiming to blame anyone but I just want my instance back. I know somewhere underground there must be backup images of the whole systems that's normally inaccessible visually but only some allowed tech specialists may access. Is there anyone authorized to do this or to assist me on finding the correct person in charge? Thanks in advance.lg...

Hi, I have a cancelled spot request that has not been deleted for 2 months. The state is displayed as cancelled and all instances were terminated, why is the request remained on the Spot Requests list? Any help would be appreciated. Thanks!lg...

Hello, I installed WordPress on Amazon AWS (EC2 Instance) The problem is that my website is accessible from ipv4 address, public DNS and domain name. Like for testing purpose i used decodewithdude.ga The domain is accessible from http://13.233.253.149/ https://ec2-13-233-253-149.ap-south-1.compute.amazonaws.com https://decodewithdude.ga I want the instance only be accessible to public from domain name. Thankyoulg...

I'm trying to understand what could cause AWS Batch jobs (using EC2 spot instances) to be at times seemingly stuck in "RUNNABLE" state for several hours, before finally getting picked up. This annoying behaviour seems to come and go over time. Some days, the very same jobs, configured in the very same way, using the same queues and compute environments are almost immediately picked up and processed, and some days they will be in RUNNABLE status for a long time (recently I experienced 3 to 6 hours). The usual troubleshooting documents don't help, as they seem to only cover cases where the job *never* gets picked up (due to configuration issue, or mismatch of vCPU/memory between job and compute environments). What I observe when I hit these issues is that there doesn't seem to be any spot request shown in the EC2 dashboard. The Spot instance pricing at that time, for the type of instance I need (32 vCPU, 64Gb memory) is not spiking (and I've set it to a limit of 100% of on-demand anyway). So one theory is that there is no spot instance available at all at that time but 1) that seems unlikely (I use eu-west-1) and 2) I can't find any way to validate that theory. My account limits on M and R instance types (the ones typically be used when the jobs are running) is very high (1000+), so that's also not the reason as far as I can tell. Anyone with any theory and suggestion? For now, my solution is to change the queue to add a compute environment with on-demand instances, but that more than doubles the price...lg...

Hi ! Tried to do the test to interrupt a spot instance as this link https://docs.aws.amazon.com/fis/latest/userguide/fis-tutorial-spot-interruptions.html But unfortunately after started the Experiment, it always returned Failed state with message ``` Target resolution returned empty set ``` But by comparing the exported JSON, it's exact the same, no idea why this happened. Also the Target's Resource ID fields seems like broken, it could input EC2 ARN or anything, can I specify the spot instance ID or ARN to simulate interruption ? Thanks a lot !lg...

Is it possible to check how much instance capacity exists for a given region and AZ? Use case: trying to determine the best instance types to choose to have the highest likelihood of reservation success. Reduce seeing this: **X instance is out of capacity for y availability zone in us-west-2**lg...

I have a spot instance(with stop behavior) which I am trying to stop but the console gives error that "Instance could not be stopped because it belongs to fleet". [ScreenShot](https://ibb.co/ZVnc837) Any idea what I am missing. Thanks in advance.lg...

Good afternoon. I want to apologize for the possibly wrong question. I am not a native English speaker and my question may be misunderstood. But I will try to ask my question as correctly as possible in order to find a way to solve it. There is a client-server application. The client has an instance. The server is in the Enclaves. In order for the client to connect to the server, the client must send a request to Credenshales. On the client, the script creates a file that temporarily creates credentials for such a connection. These credentials are copied from the server's memory and copied into this file. (temporarily) This file is then deleted. I would like to somehow protect myself and somehow encrypt this file or find an alternative **SAFE** solution how to bypass this process and use other tools that Amazon AWS has. Is it possible to somehow automate this process and make the transfer of credentials that the client takes from the server and inserts into its application. Because the credentials are temporarily stored unencrypted, I think this is a serious vulnerability for my application. It is enough for me to give an idea to solve my problem. Then I'll try to figure it out myself. AWS contains a fairly large amount of materials and it is very difficult to find the right topic. I am sure that in his tools he will be able to offer a solution to my problem. Thanks.lg...

Hello AWS Team, I have just created my account and I want to make an EC2 Spot request and I have some questions. I have made the technical configurations and pre-requisites in order to request for an instance but I want to clarify how this is charged. For example when I proceeded with some request and have been provided with a fullfiled - active instance I couldn't shut down the instance because it was not persistent . If I create a non-persistent does charges apply hourly even I don't use / I am not connected to the instance? If this is the case then could you please advice me how to create a persistent spot request and leave it shut down and use it only when I want in order for charges to not apply at the time I don't use it ? Thanks in advance !lg...

Hi, community members, I am new to AWS cloud service, and I want to use spot GPU instances to train DL models. I wonder can I know the size of spot capacity pools at any time? Since preemption may occurs due to capcaity reason, I want to know whether the change of capacity is available to users. Thanks a lot!lg...
