I can see it would work as-is easily on a cloud. Two clouds could
serve the same content to the closest customers without any change at
all. My questions are:
1. how to do you update the files of a cloud? Can I get rid of that
accursed FTP?
2. do you have to update each cloud separately, or is that considered
an automatic cloud function?
Now lets say I migrate the random functions (e.g random PSAs, random
ads, random quotations) to the cloud. Again no problem.
Now lets say I had some SQL databases that get queried to satisfy
requests. I guess then I have to upload the entire database from time
to time and propagate it? or do I? Is it considered an ordinary
function to send some sort of delta?
Now lets say I want to keep track of hit counts. I want to
consolidate the page hits from each cloud. I could download each
cloud's database consolidated and upload to each cloud. I could have
only one cloud maintain the database and other clouds access it
remotely with jdbc or something more secure. Is there some special
distributed cloud database that lazily keeps all copies in sync?
IaaS : depends on your application
PaaS : depends on your application and the clouds capabilities
SaaS : depends on the clouds capabilities
I have a lot of static content on my website. Turning every page to a
JSP servlet would make for one huge server app. What sort of
techniques are used to separate static and computed parts to glue
pages together?
A) Just let the servlet container serve both dynamic and static
content (possibly with different paths)
B) Use a servlet container for the dynamic content and a plain web
server for static content
I take it the locations of clouds are not your concern. They could
wander from server farm to server farm based to where the load is
coming from and there there is spare compute power. Right?
More or less. You will typical be able to specify region.
Anything else I should consider in such a move?
There are probably no point in moving your pages to a cloud
instead of the current web hosting solution.
probably look for a CDN not for IaaS/PaaS/IaaS. The CDN provider
