The community is currently in the process of defining Cloud-Native Network Functions (CNFs). Due to the differences between the current modern architecture and cloud-native environment, many questions will arise about how to create, consume, operate, monitor and scale CNFs. As CNFs gain in popularity, it will become increasingly important to have a set of guidelines to help the community maximize the benefit received from running in the new Cloud-Native environment.

When cloud-native arrived, it was often unclear how web applications should be designed or rearchitected to make use of cloud-native infrastructure. Many mistakes were repeated due to a lack of guidance. In response, Adam Wiggins and others created a methodology known as 12 Factor Apps. 12 factor apps guide developers towards building applications capable of taking advantage of cloud-native infrastructure. These properties include but are not limited to:

Easier on-boarding for developers
Maximize portability
Deploy on modern cloud platfor

If you'd like to experiment with Terraform and Kubernetes on macOS locally, a great provider for doing so is the Kubernetes provider. You can get set up in a few simple steps, like so:

1. Install Docker

Install Docker for Mac if you have not already.

Введение

Начать стоит отсюда. Не пугайтесь то, что это книга по незнакомой OS, эти термины практически везде одинаковые и здесь они изложены в понятной для начинающих форме.

http://www.qnx.com/developers/docs/6.4.1/neutrino/getting_started/s1_procs.html

Прочесть нужно треть главы до подраздела "Starting a process", если С не пугает, читайте полностью. После прочтения вы будете понимать, что такое process, thread, mutex, priorites, semaphores, scheduler, contex-switch, kernel states.

	1. Open a command prompt and navigate to /etc/nginx/ssl
	2. issue "openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out server.csr"


	3. Get your certificate - Go to your certificate authority and give them the CSR

	4. copy your new crt to the /etc/nginx/ssl and give it read priveledges

	5. reconfigure your nginx.conf, here is mine. The first part redirects 80 to 443, the second part listens to 443 and is optimized to return Ruby on Rails application requests using gzip and unicorn.
