| | Noise is also less of a concern, but power consumption and heat output can be a serious issue.
Uninterruptible power supplies might be incorporated to guard against power failure. These will normally have very stable power and Internet and increased security. A2 promises 99.9% uptime, and delivers this thanks to a 24/7/365 support staff, quality data centers, up-to-date security patches, and 10GB redundant network to pick up the slack in the event of a failure.
Internet (network) slowdowns (e.g. due to packet losses) so that client requests are served more slowly and the number of connections increases so much that server limits are reached. HTML and embedded source code that is interpreted and executed on the fly, e.g. index.asp, and / or by supporting the usage of dynamic index programs such as CGIs, SCGIs, FGCIs, e.g.
index.cgi, index.php, index.fcgi. The problem about how to further efficiently speed-up the serving of static files, thus increasing the maximum number of requests/responses per second (RPS), started to be studied / researched since mid 1990s, with the aim to propose useful cache models that could be implemented in web dedicated server global (https://controlc.com/07840004) programs.
Historically, static contents found in files which had to be accessed frequently, randomly and quickly, have been stored mostly on electro-mechanical disks since mid-late 1960s / 1970s; regrettably reads from and writes to those kind of devices have always been considered very slow operations when compared to RAM speed and so, since early OSs, first disk caches and then also OS file cache sub-systems were developed to speed up I/O operations of frequently accessed data / files. |
