I'm a cloud student.
The number of simultaneous users of the banking apps is 50 million. The average number of users is 10 million and the minimum is 9 million.
I wonder how to set the instance type (CPU, Memory) at this time.
Also, I wonder if there is a standard for setting this.
Thank you.
Hi,
1. I have created a new environment (tomcat) with Elastic Beanstalk and uploaded my war application.
2. Application works fine with http (80)
3. inbound port https 443 entry created into respective security group.
4. New Load Balancer created.
5. Listener 1 http redirect to https 443
6. Listener 2 https forward to a target group (ssl selected)
7. Target group created with port 443 directed towards the respective instance.
8. After some time, Target group always shows health status as unhealthy.
Kindly suggest.
I don't have mysql dump files and log files, but is there any way to recover the data?
It's really important data, so I'd really like to know how to recover it.
Hey,
Since 24 hours, my site is down with the message
"503
Service Unavailable
The server is temporarily busy, try again later!"
My WordPress website And My Cyber Panel Give this message :
" A timeout occurred Error code 524 "
When i try to log into SSH Terminal, i always get "Connection timed out" so I'm out of solution, i did try everything in the documentation, but nothing seen to work, so i conclude that it's server side issue, so I'm out of idea how to get my instance working again and having access to SSH.
The instance status check is failing on my windows server. Now when i replace the volume it runs again but with my current volume the server is not responding. I just want my data from this faulty volume. So i can move this data to another volume and run.
I don't have any image or screenshots of this volume from earlier. I tried creating new volume and attaching this volume as additional storage but it doesn't show up. I tried creating screenshots and then creating new volume and attaching this volume. but the problem is same.
The server is down, the operating account is the root account, the server termination protection is disabled, but it cannot be terminated and restarted
The error message is
This request has been administratively disabled
I have an Auto Scaling Group using Lifecycle Hooks; the ASG is hooked up to an Elastic Load Balancer as well. When I perform an instance refresh on the ASG, the instances complete their launching lifecycle action relatively quickly and enters the `InService` state. However, the instance refresh then pauses for about 90 seconds after each instance enters the `InService` state, and the instance refresh status reason reads as following:
```
Waiting for remaining instances to be available. For example: i-XXXXXXXXXXXX has insufficient data to evaluate its health with Elastic Load Balancing.
```
Both the health check grace period and instance warmup are set to zero, and the associated target group is configured to consider instances healthy after 2 successful health checks with a 10-second interval. Given that, I'd expect to spend at most 20 seconds waiting for ELB health data, not the nearly 90 seconds I observe in practice. How can I configure my ASG to proceed with the next instance replacement immediately after the previously-replaced instance enters the `InService` state?
while connecting to ec2 instance through ssh tool like git bash i am getting above said connection timed out error. it is getting after waved off of bill only. and i have tried with different regions and with pem file and ppk file in putty also.
i wanted to know is there any problem with payment or something else.
Hi, I have created a Linux EC2 instance and added an /dev/sdf volume. After creating a filesystem plus mount point I could run umount and then mount -a without issue. However when I shutdown the instance and later restart the filesystem is not auto-remounted. Mount -a fails with various errors about missing code-page but I can manually remount the filesystem without problems. I have followed AWS advice on configuring /etc/fstab but still have the problem - Any thoughts? Kr Ian
When I launch a simple EC2 instance and open the IP address, I get an Error as "Your connection was interrupted". It used to work before, but I don't know what might have caused all of a sudden.
I even checked the security group and it's correct as far I know, as I have given HTTP & SSH for inbound and All Traffic for outbound.
Is there anything else to check or configure? I'm still learning the basics in AWS.
Let me first preface this that I also use cloud VPS with many other services such as Linode, Digital-Ocean, have use google's services as well, etc, and this is the first time that I experience massive connection issues with the instances after being created. With other services, everything just runs as smooth as butter and I am trying to understand what is going on.
Basically, what is going on is that I create a micro Ubuntu instance, and then I SSH into it just fine. Install a few apps such as Docker, everything very light weight, can't really do much with them yet anyway with the many connections issues.
Then what happens, is that all of a sudden, out of the blue, the SSH connection will get dropped and I won't really be able to get back in for a while. I will basically have to wait then completely shut down the instance, and then reboot it.
Recently, I even got a 1 out of 2 checks passed on my EC2 Dashboard, and the one that failed was actually connectivity.
I have no clue what is going on. At first, I thought it was due to the IP changing, and I realized I may have to connect using a new IP, and the I set an elastic IP for the instance, but the same issue still happened again.
Can someone help me with this? Thank you.
A bit confused... In the case of BM instances, so AWS actually assigns an entire PHYSICAL server platform to one customer? How can AWS possibly scale like that? Let's say a customer needs 100 BM servers... and there are 1,000 customers like that... AWS is going to have to have 100K physical boxes to support them?? How could that be? I feel like I am missing something - besides a brain lol
Part 2: Why is it still called an EC2 instance? I always associate an EC2 instance to a virtual construct -- a VM.
