NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

The Why and When of Choosing Elm

What is Elm?

Language (and "framework") for building web frontend applications
Can be used in place of HTML, CSS and JavaScript
Compiles into the above

Should be work with 0.18

Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !

Tuple

myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))

A vision for data interchange in Elm

How do you send information between clients and servers? What format should that information be in? What happens when the server changes the format, but the client has not been updated yet? What happens when the server changes the format, but the database cannot be updated?

These are difficult questions. It is not just about picking a format, but rather picking a format that can evolve as your application evolves.

Literature Review

By now there are many approaches to communicating between client and server. These approaches tend to be known within specific companies and language communities, but the techniques do not cross borders. I will outline JSON, ProtoBuf, and GraphQL here so we can learn from them all.

	## Install NGINX
	## when installing on Amazon Linux AMI, use:
	$ sudo yum install nginx -y
	## when installing on Amazon Linux 2 AMI, use
	$ sudo amazon-linux-extras install nginx1.12 -y

	## Install PHP and PHP-FPM
	# for PHP version 7.1 use php71 and php71-fpm instead
	$ sudo yum install php -y
	$ sudo yum install php-fpm -y
