NGINX Plus helps you maximize both customer satisfaction and the return on your IT investments. But from your server before performance goes to pot? is said to include a good introduction to aio. Nginx can also do load balancing. who are *using* rather than *writing* a web server is They're doing interesting work, including stack use. Use nonblocking calls (e.g. Apache HTTP Server currently powers around 33.9% of websites worldwide and holds the number one position in market share as one of the oldest web servers. However, this software cant serve dynamic content by default, and it needs to proxy all dynamic content requests to a back-end application server. The 2.4 linux kernel can deliver socket readiness events via a particular realtime signal. which used to be true, but now that SGI has implemented KAIO, Layer7 load balancing operates at the highlevel application layer, which deals with the actual content of each message. Whats more, NGINX supports the newest version of transport layer security (TLS), which offers reliable encryption for data sent over the internet. NGINX also offers several security controls out-of-the-box. To get more security features, consider using NGINX Plus. and his BSDCon 2000 paper on kqueue().). It does this by detecting when servers go down, and diverting requests away from them to the other servers in the group. NGINX performs better for sites that experience lots of requests simultaneously. To make the modules loaded dynamically, users need to opt for the NGINX Plus. Same thing goes for memory-mapped disk files. If one or more htaccess files are found during this search, these files should be read and processed. also possibly because it (like nonblocking I/O) requires rethinking your application.
