Spike system roughly divided into three blocks. The client, server, and management background.
Spike high concurrency systems with large flow characteristics.
For web front-end processing, typically static pages + CDN distributed cache.
Since the processing speed of static pages is the fastest. Suppose a single server nginx, static page requests can be processed within one second is 1w, the processing program may be php 500 per second. So we sent a lot in efficiency. The reason is part of a dynamic php language, the server needs to explain to run, among which may be a large number of I / O operations, load expansion. This process is relatively long lead time.
So for the spike products are generally in activities about to start, on-line static pages.
