When testing I have noticed IrisCouch to be slower, but the micro EC2
instance really isn't experiencing a real load either. Could be any
number of factors such as PHP EC2 to Couch EC2 micro vs PHP EC2 to
IrisCouch. Internal network vs external.
A programmer I know with pretty extensive server experience thought a
micro would be fine as it's just many small IOs, but his experience with
AWS is minimal and CouchDB is zero. My gut disagrees, but what do I know?
I am trying to sort through all of this, thus me asking for instance
sizing advice. Thought I might get some feedback from the people with
experience.

I'd love to hear if IrisCouch is slower an a micro EC2 instance, I'd be astonished. Using
a micro for anything serious, like a production database, is "penny wise, pound
foolish" imo.

Hello
Let's see if I can articulate this sufficiently.
Some background: I am a one person shop, I wear all the hats and I have been
learning everything as I go for the last 18-20 months, so I am still a bit of a
noob.
I have an iOS app created in Titanium using Pegli's ti_couchbase module. If the
user wants to enable syncing, they enter their requested GroupName, Password,
eMail address. The app reaches out to a php document that uses php-on-couchdb
to check if the GroupName (database name) is available, if it is, that database
is created with the proper authorization/password. This all works great and I
am very pleased with it.
I am currently running everything into IrisCouch. I am considering changing
over to AWS as IrisCouch seems a bit slow, plus last week they were down all
morning one day. I have everything up and running on an AWS micro instance.
(Couchdb 1.2). In fact I have two instances, Couch A and Couch B. Couch B is my
backup server and has a cron job running a script to continuously replicate
everything on A to B.
The current version of my app has about 3k users. If history is an indicator,
when this syncing version is released, I expect about 250 users (world wide)
per day to update to the sync version. I expect 80% will enable syncing. The
numbers I am anticipating are 200 people per day creating a database initially
syncing 300-600 documents (2-4Meg per db). The Couchdb server is for
replication only.
After the initial updates I anticipate an average of 15 users per day growth,
databases created with less than 20 docs to start.
Using Cloudant is not an option at this time and I would rather get away from
IrisCouch.
Will a Micro instance be sufficient or will I need to go larger?
Thank you for the help and advice!
