Wordpress website hosted on AWS downs frequently

Question

Hi, I hosted a Wordpress website on AWS (1 GB RAM, 1 vCPU, 40 GB SSD), but the website always goes down - the frequency ranges from daily to weekly and each time it goes down for 1-2 hours. The max traffic of my website is ~ 2,000 visits and well below the sustainable zone. And the website resumes after I reboot the instance, and sometimes it resumes itself.

Do you know if there is a way to determine where the problem might be? Should I upgrade my bandwidth? Thank you.

Answer

You may want to check the Cloudwatch metrics and logs to monitor the resource utilization on the machine.

You can also create an auto-scaling group and put an Application Load Balancer in front of the auto-scaling group, so that more instances will be spun up if the load on your website increases.
