NGINX Announces Eight Solutions that Let Developers Run Safely with Scissors
Technology is hard. As technologists, I think we like it that way. It’s built‑in job security, right? Well, unfortunately, the modern application world has become unproductively hard. We need to make it easier.
That’s why I like describing the current developer paradox as the need to run safely with scissors.
NGINX Balances Developer Choice with Infrastructure Guardrails
Running with scissors is a simple metaphor for what is the admittedly difficult ask we make of software engineers. Developers need to run. Time to market and feature velocity are critical to the success of digital businesses. As a result, we don’t want to encumber developers with processes or technology choices that slow them down. Instead we empower them to pick tools and stacks that let them deliver code to customers as quickly as possible.
But there’s a catch. In the world of fast releases, multiple daily (or hourly or minutely!) changes, and fail‑fast development, we risk introducing application downtime into digital experiences – that risk is the metaphorical scissors that make it dangerous to run fast. On some level we know it’s wrong to make developers run with scissors. But the speed upside trumps the downtime downside.
That frames the dilemma of our era: we need our developers to run with scissors, but we don’t want anybody to get hurt. Is there a solution?
At NGINX, the answer is “yes”. I’m excited to announce eight new or significantly enhanced solutions built to unleash developer speed without sacrificing the governance, visibility, and control infrastructure teams require.
Load Balancing and Security DNS Solutions Empower Self‑Service
As my colleague, Gus Robertson, eloquently points out in his recent blog The Essence of Sprint Is Speed, self‑service is an important part of developer empowerment. He talks about developers as the engines of digital transformation. And if they’re not presented with easy-to-use, capable tools, they take matters into their own hands. The result is shadow IT and significant infrastructure risk.
Self‑service turns this on its head. It provides infrastructure teams with a way to release the application delivery and security technologies that developers need for A/B, canary, blue‑green, and circuit‑breaker patterns. But it does so within the guardrails that ensure the consistency, reliability, and security that ensure your apps remain running once in production.

Basics of configuring NGINX
NGINX is a modern technology that is used for mainly for load-balancing but more different purposes. Even though it looks like a very complex technology, if you get to know the basics, it is very simple to work with NGINX. In my experience I also thought NGINX is a handful, but after learning the basics and moving on it was very simple and easy. So, before digging into the configurations let me take give you an introduction to NGINX.
Introduction to NGINX
NGINX is a web server that can be used as a reverse proxy, a load-balancer, a mail proxy, or an HTTP cache. It can be deployed in your local machine or in any cloud. Nginx has grown in popularity since its release due to its light-weight resource utilization and its ability to scale easily on minimal hardware. NGINX has many products but in this article, I will be explaining using NGINX Open Source version.
Other than NGINX, there are many other load-balancers used in the industry such as.
- Traefik — a modern microservices-focused application load balancer and reverse proxy written in Golang.
- Seesaw — is another open-source load balancer written in Golang. It was originally created by Google SREs to provide a robust solution for load balancing internal Google infrastructure traffic.
- HAProxy — offers reverse proxying and load balancing of TCP and HTTP traffic.
- Neutrino — is a Scala-based software load balancer originally developed by eBay. Neutrino’s strength lies in the broad compatibility of its runtime environment, the JVM.

Nginx Commands - Every Developer Should Know
Nginx pronounced “engine x” is a free, open-source, high-performance HTTP and reverse proxy server responsible for handling the load of some of the largest sites on the Internet. It can be used as a standalone web server, and as a reverse prox for Apache and other web servers.
If you are a developer or system administrator, chances are that you’re dealing with Nginx on a regular basis.
In this guide, we will go over the most important and frequently used Nginx commands, including starting, stopping, and restarting Nginx.
Before You Begin
We’re assuming that you are logged in as root or user with sudo privileges. The commands in uide this gshould work on any modern Linux distribution like Ubuntu 18.04 and CentOS 8 and Debian 10.
Starting Nginx
Starting Nginx is pretty simple. Just run the following command:
sudo systemctl start nginx
On success, the command doesn’t produce any output.
If you are running a Linux distribution without systemd to start Nginx type:
sudo service start nginx
Instead of manually starting the Nginx service, it is recommended to set it to start on system boot:
sudo systemctl enable nginx
Stopping Nginx
Stopping Nginx quickly shuts down all Nginx worker processes even if there are open connections.
To stop Nginx, run one of the following commands:
sudo systemctl stop nginx
sudo service stop nginx
Restarting Nginx
The restart option is a quick way of stopping and then starting the Nginx server.
Use one of the following commands to perform an Nginx restart:
sudo systemctl restart nginx
sudo service restart nginx
This is the command that you will probably use the most frequently.
Reloading Nginx
You need to reload or restart Nginx whenever you make changes to its configuration.
The reload command loads the new configuration, starts new worker processes with the new configuration, and gracefully shuts down old worker processes.
To reload Nginx, use one of the following commands:
sudo systemctl reload nginx
sudo service reload nginx
Testing Nginx Configuration
Whenever you make changes to the Nginx server’s configuration file, it is a good idea to test the configuration before restarting or reloading the service.
Use the following command to test the Nginx configuration for any syntax or system errors:
sudo nginx -t
The output will look like below:
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
If there are any errors, the command prints a detailed message.
Viewing Nginx Status
To check the status of the Nginx service, use the following command:
sudo systemctl status nginx
The output will look something like this:
nginx.service - A high performance web server and a reverse proxy server
Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
Active: active (running) since Sun 2019-04-21 13:57:01 PDT; 5min ago
Docs: man:nginx(8)
Process: 4491 ExecStop=/sbin/start-stop-daemon --quiet --stop --retry QUIT/5 --pidfile /run/nginx.pid (code=exited, status=0/SUCCESS)
Process: 4502 ExecStart=/usr/sbin/nginx -g daemon on; master_process on; (code=exited, status=0/SUCCESS)
Process: 4492 ExecStartPre=/usr/sbin/nginx -t -q -g daemon on; master_process on; (code=exited, status=0/SUCCESS)
Main PID: 4504 (nginx)

CGroup: /system.slice/nginx.service
|-4504 nginx: master process /usr/sbin/nginx -g daemon on; master_process on;
|-4516 nginx: worker process
`-4517 nginx: worker process
Checking Nginx Version
Sometimes you may need to know the version of your Nginx so you can debug an issue or determine whether a certain feature is available.
You can check your Nginx version by running:
sudo nginx -v
nginx version: nginx/1.14.0 (Ubuntu)
The -V option displays the Nginx version along with the configure option.
sudo nginx -V
