Even though Hack Education is growing significantly, all 4 of our blogs are growing in traffic with both of us out on the road, actively attending Silicon Valley events and the amount of writing and social media activity we are involved with.
So its time to scale. My first choice would to be scale horizontally using Elastic Load Balancing and Autoscaling. Our sites use WordPress as the CMS, and our database is using Amazon RDS.
So in theory it shouldn’t be much trouble to scale across multiple
servers. The one problem is images that are uploaded through WordPress
are stored locally.
I have been manually storing all files and images at Amazon S3
for about 3 years now, but Audrey has yet to start doing this. So we
have to solve this problem. I’ve tried an Amazon S3 add-on (which
sucked), I think just manually uploading to S3 as a habit is the best
route for any content development. However I still have legacy images
on my blog and so does Audrey.
We could deploy some sort of version control for our WordPress and
create scripts that could auto checkout when an instance deploys. I’ve
done this and it works. It would be easier to just write a script to
clean up legacy images and depend on the centralization of Amazon S3 for
files and Amazon RDS for our data. Then all that is left is latest
version of WordPress which I can manage with Amazon Machine Images
(AMI). So nothing site specific is stored on the server, just a web
server w/ domain pointing at a folder with common WordPress files. Ok,
there is a config file, but this doesn’t change, it can be managed with
AMI as well.
Soooo…until we get these images cleaned up I am scaling vertically using a larger Amazon Instance. We are going to a large 64 bit Windows instance. I think a large instance is a better level to be operating from anyways. It is 64 bit and when I’m ready to load balance and autoscale, it will handle overall loads much better.
The new Amazon Large Instance is running us .48 cents per hour which at 730 hours come to about $350.00 / month. Hmmm….jump from $88 to $350. Ouch. It has to be done, so I went and looked at the Amazon Reserved Instances, and for a one year term it is $910.00. So if I prepay a year I can get it for cheaper than what I’m paying currently for a small instance. Pretty good deal…here we go.
