architecture - Architecting webserver (NginX/Lighttpd/Apache) with couchbase -


i have architectural question i'm hoping of can share me. in past experience, scenario works better high load application/dbase server. i'm using couchbase dbase , 1 of web server (nginx/lighttpd/apache). going hard explain in text hope make sense. scenario preferred?

scenario 1.

client connect webserver master cluster select proper available webserver (machine 2) , (webserver machine 2) connect dbase master cluster in turn select available dbase (dbase 1)

scenario 2.

client connect webserver master cluster select proper available webserver (machine 1) , "machine 1" connect couchbase machine in couchbase cluster that's already assign "dbase 1".

does make sense? thought on preferred method?

i have done in past; , simple

client connects load balancer (which contains multiple machines), load balancer keep incoming load balanced, , make system horizontally scalable.

and either 1 of load balanced servers talk dbase @ couch; sure can create cluster of couch well.

now q. of using nginx or apache; q. must answer "is content getting served via webserver - highly static or dynamic - means coming db" if static chose nginx; if not should go apache.

if using php, may use apc or hip-hop compile php https://developers.facebook.com/blog/post/2010/02/02/hiphop-for-php--move-fast/

there lot of things should take care of while designing scalable system.

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
