Recently, we have migrated your site on Amazon servers. Right now, we have a multi-server architecture having
2 EC2 r3.xlarge instances
2 RDS, one for blogs and other for Magento
I am not sure if the current architecture( Implement by Certified AWS company) is perfect, but i have few issue/queries that i am curious to know
When we need to import a file ( inventory for e.g.) vis Data profile on which instance that files will be uploaded? How do Magento picks the files from correct instance where files are uploaded. I have faced issue saying file not exists when I tired to run data profile.
If we upload any images for a CMS pages, then will image file be uploaded on server first and then on CDN or directly on CDN? If the files are loaded on Instance first then how to CDN know on which instance files are uploaded?
I have tried to search on Google a lot but never got any satisfactory results.
Can anyone please provide their comments/suggestion for above.
