[official docs only says t2.micro Network Performance is Low to Moderate](https://aws.amazon.com/ec2/instance-types/), I think it is very confused. I want to know specific amount: 1Mbps, 1Gbps or others?
Because I want to do TCP optimize, tune my debian server, like [this tutorial](https://cloud.google.com/architecture/tcp-optimization-for-network-performance-in-gcp-and-hybrid) and [this tutorial](https://aws.amazon.com/premiumsupport/knowledge-center/network-throughput-benchmark-linux-ec2)
I have one t3.micro instance and it has java sample application running java is consuming approx. 60% of mem where as some other stuff has around 20% totally instance is having 80% of memory utilization.
When I saw my instance it says that under provision then i dig in details in metric tab i see mem is under provision it has 2 graphs current is up to 85-87% and option1 is 40-43%.
I got confused because with same setup i have one more instance which is not showing as under provision what should i do now should i upgrade it.
Amazon connect supports things like Amazon polly for converting text to speech. Is it possible to replace polly with a third party text to speech like Google's API? I want to use Amazon connect but want to replace parts of the infrastructure with 'non-Amazon' APIs.
I have two instances, Instance1 and Instance2. I ran a reachability analysis on the path from Instance1 to Instance2, and it succeeds. However, when I connect to Instance1 and run `nc -z -v [dest IP] [port]`, I receive "no route to host".
What am I missing?

We are running an email processing application for one of our client, here they send the emails via smtp to our servers and before delivering the emails to the final MTA we are supposed to do some process on the incoming SMTP packet like adding tracker information. Currently we are doing this on an stand alone server at a data center in US which has Intel Xeon E3-1270v6 - 4c/8t - 3.8 GHz/4.2 GHz with SSD drives and 64 GB RAM.
Here we are able to process very easily 130 - 150 mails per second.
Now when we moved this to AWS EC2 on a c6a.4xlarge the same process is hardly processing 50 - 60 mails per second.
Is there any throttle on AWS or have we selected a wrong EC2 instance ?
Please guide.
Is there any possibility to configure site to site VPN on a LightSail Linux Bundle. Setting up my development environment and trying to configure wireguard for ssh tunneling. Appreciate your help!.
On AWS EC2 instance I've installed Bitnami and on top of that I've installed Wordpress and a Wordpress theme.
After few months of customization few days ago I stopped and started the instance. Since then my site is unavailable.
I am trying to bring the site up and for this I've found this tutorial: https://www.youtube.com/watch?v=xvtoVxk8kWA
Following the tutorial I can say the following:
* Status check for sys. reachability successfully passed
* Status check for instance reachability successfully passed
* Security groups look ok from my perspective
* Network ACL looks ok from my perspective (all traffic allowed)
In the tutorial (time 4:20) it says to start the following command:
`sudo systemctl status httpd`
When I run this command I get the following output
`Unit httpd.service could not be found.`
I tried running this command as "root" and as "bitnami" user. In both cases I am getting the same error message.
In the aforementioned tutorial in the comments someone wrote that "sudo systemctl restart httpd" worked for him. But when I run this command I still get "Unit httpd.service not found.".
Bottom line is - I am trying to bring the site up. This way or any other way. All checks which video describes until 4:20 minute look same/similar on my end. That's why I am trying to bring it up with "sudo systemctl...". can anyone please help me with this? Thanks!
Following the video (4:41) I've run this command to check if the traffic is received on port 80/443:
`netstat -tunlp | grep -i http`
I don't get any result (at least not the result as shown in the video). Based on this I conclude that the site is NOT listening on port 80/443
I tried running this command and here is the result
`sudo firewall -cmd --state
sudo: firewall: command not found`
If I run
`sudo /opt/bitnami/ctlscript.sh status`
Then I get this result
`
apache already running
mariadb already running
php-fpm already running`
Can anyone please help me to bring the site back up? The matter is urgent and critical. Thanks for support and understanding.

Re. "connectivity":
this is how my inbound rules are defined: https://prnt.sc/ieCq2NSsX6B6
--------------------------------------------------------------------
This video (https://www.youtube.com/watch?v=uLmjoHDCkag) shows how the issue with unreachable site is resolved (14:56 min).
However, when I connect as bitnami user I can't run the commands show in the video.
On the other hand, if I try to connect with the instance over console-aws either as "admin" or "ec2-user", I get the following error
`Failed to connect to your instance Error establishing SSH connection to your instance. Try again later.`
Why can't I connect with the instance?
Hi,
On AWS EC2 Ubuntu 20.04 and earlier, I was able to set up a crontab to shut down the instance at night.
`0 5 * * * /sbin/shutdown -h now`
On Ubuntu 22.04 the server automatically restarts again. Could this be modified so the `shutdown` command works correctly?
Thanks.
I want to create a new instance with the AMI created of the old instance and also want to retain the Private IP address of the old instance as well. Is this possible?. If yes, How can this be done?
I am not using any instances of EC2. I am not using any service in AWS. I have verified all other resources that have connection with EC2 like Elastic Bean stalk and so on. The only service that was active on my account is AWS Budget for free tier limit. Every month, I am getting a message saying that 85% of my usage limit got exhausted. How do I further check on this. If i leave this as it is, I might get a bill with some decent amount once my free tier tenure gets completed.
Can someone help me in this regards?
Hi, I am trying to launch a g5.48xlarge instance. But it kept saying my configuration was not supported.
My configuration is listed below:
Region: US-WEST-2 (Oregon)
AMI: I choose one Ubuntu AMI from the "Community AMI" from verified provider and the AMI explicitly says it support G5 instance.
Networking: I just choose the default existing group
Storage: I tried GP3, GP2, IO1, IO2 (requiring 2200 GB)
Can anyone help me here? Also, I have encountered issues in launching P4 instance and cannot find any tutorial documentation. It is good to provide templates for each instance, so people know what should choose and what should not.
Thanks.
