AWS EC2 MacOS Monterey Apple Silicon Initialize Error
Hi, I wanted to create a new MacOS Monterey Apple Silicon Instance (not Intel or x86_64/AMD64) but it always runs into this error message. **Instance launch failed** Launch log: Intializing request: Succeded Creating security groups: Succeded Create security group rules Succeeded Launch initiation Failed AMI ID ami-01a9da8de3d589094 macOS Monterey 12.4 AMI built by Amazon Web Services Architecture: 64-bit (Mac-Arm) Virtual server type (instance type) mac2.metal Family: mac2 8vCPU, 16 GBytes Memory
With a Security group I can't connect to EC2 instance
Hello, I have a security group which allows inbound traffic to port 22 from the world 0.0.0.0, then I created an EC2 instance with that security group attached but I can't connect to the instance, the instance of course has an external public IP (AWS assigned one inside 3.24x.x.x range) but I cant' connect, this instance is in eu-west-1 (Ireland), I don't even get a response using telnet on port 22 while trying to connect to it, however, if I create an EC2 instance with the same SG rules (different SG because it's different region but the same rules) in eu-west-3 (Paris) I can connect. I tried this many times with the same result, thank you for any help
EC2 outbound bandwidth dropped on July 21st and stays very low (eu-west-1)
Hello, In our organization, we run our CICD using gitlab. We spawn runners on demand and each runner is a EC2 instance. Since July 21st, the uploads performed by these runners got their duration multiplied by ~10. From our tests, we see that: - outbound bandwidth from any instance type and any AMI we can spawn in eu-west-1 is now <2,5Mb/s (~300KB/s), - we tested t3.medium and m6a.large, - we tested various AMIs (ubuntu, amazon linux), - this seems far from any quota/limit/advertised bandwidth, - before July 21st, it was around 25Mb/s (~3MB/s) for t3.medium runners, - download speed is 500Mb/s, - upload/download target is the gitlab server host itself, - located in Paris, - can be reached through 2 different physical connections and we get very good speed from other places, - all speed tests mentioned here are performed using iperf3, - runners are in a VPC, routed through an Internet Gateway, - if we spawn a runner in eu-west-3, outbound speed is 24Mb/s (and download is 1Gb/s), - that's not great, but at least it’s 10 times what we get in eu-west-1 (and close to what we had before “the incident”). - we haven’t changed a thing regarding our configuration, runners, gitlab version, code. The problem happened suddenly for pipelines run after July 21st, 4pm cest, We may consider spawning our runners in eu-west-3, or even move our gitlab server on EC2, but since 1) the problem happened suddenly without any action on our side and 2) this would require moving other resources as well, time, effort and cost, we’d rather prefer a logic explanation of what’s happening here before taking actions. We are looking for clues to understand: - how to monitor this in order to identify if we actually reach a limit/quota, - why this changed suddenly, - why outbound bandwidth is that low (is that to be expected, or not). Any help investigating would be greatly appreciated! Best,
How to check the cause of high ec2 CPU usage triggered by cloud-watch-agent
I'm running EC2 instance and sometimes the CPU usage goes by 90-100% at intervals. and it was triggered by cloud-watch-agent. I assume it's because of the old file logs. but I want to know which logs are causing this high CPU usage from cloud-watch-agent and which logs should I delete?
Installation of jupyter notebook on Deep Learning AMI GPU TensorFlow 2.9.1 (Amazon Linux 2)
I've been unable to install jupyter notebook seemingly regardless of the virtual environment I have set on Deep Learning AMI GPU TensorFlow 2.9.1 (Amazon Linux 2). Has anyone successfully managed this? The error is the oft occurring: ModuleNotFoundError: No module named 'pysqlite2' But as most of the solutions involved rebuilding python, I don't want to do that given this is a distribution for which jupyter is typically the go to tool for such an AMI.

Moving resources between AWS accounts
We have a number of EC2 Linux instances running in a legacy AWS Account in a different OU. Our plan is to create a Linux AMI, and move those to a new OU/AWS Account. VPCs, and Security Groups have been replicated to the new AWS Account. (1) What's the recommended method to move these instances? (2) Some of them have elastic IPs; can they be retained?
Does Microsoft SQL Server 2019 Standard on Windows Server 2019 include SSRS?
We are interested in adding an EC2 with Windows Server 2019 with Microsoft SQL Server 2019 Standard AMI. We want o add SSRS 2019 standard on the SQL Server instance. Does SSRS included in the AMI? If not, can we install SSRS 2019 standard without addition license? Thanks Amy
Amazon Elastic Compute Cloud Dedicated per Region Fee with Reserved Instances
I'm being charged dedicated per region fee ($2 per hour) with the following setup: * 1 reserved EC2 instance purchased with dedicated tenancy. * 1 dedicated EC2 instance with matching configuration running. Does this mean that RI does not cover dedicated per region fee and there's no way to avoid this additional cost?
