Can you help me with my capacity planning?
Having worked for weeks on a new mobile app product, we are finally preparing a public launch in the coming weeks. However we wonder if our Europe based servers will be good enough (latency, etc.) for american users. Tested on
dotcom-monitor.com and we got around 150ms for CA. Is it good enough?
We are exploring EC2 options but it is way more costly than local dedicated hosting, and I've been told that you should not care / work that much on scalability at early stages.
Considering the time&cost it would take to go to a replicated EC2 worldwide setup, we are not sure wether we want to commit on this too soon.
- More info about the BW usage :
On startup, the app performs 3 ajax request to our API (1 login + info & 2 indexes). Typical bw usage would be around 5k (gziped). From europe the biggest request takes 62ms connecting (34ms ssl) & 140ms processing. After that, the app is 100% usable, it will only perform one request at a time on user interaction / push.
