WP-Cron.php Got my website suspended!

Hello,

A few days ago I received an e-mail from my host that they won’t host my blog anymore due to the load on resources caused by wp-cron.php.

Searching in the forums I noticed that this problem existed for many people for years.

I have just moved my blog to the cloud (AWS), hoped that the problem will be gone if i replace some file but it is not.

The website is very slow, and the server reports show that the memory usage is almost to the limit and I only had the blog up for less than 3 hours! (Using AWS Micro instance)

I would really help if any one have any recommendations to fix this issue as I am really a WordPress user not a developer/maintenance kind of guy.
This is my website if needed for any reason (Not in English):
https://drhariri.com/blog/

If you need me to print any logs, please let me know!

Thanks!
