Run Apache, Nginx & HAProxy on Same Server

If you’re a server admin, you probably have a web server of your choice like Apache, or Nginx. Apache is a well-known web server since the 1990s. Nginx was first developed in 2004 and quickly gained traction due to its lightweight memory footprint and fast processing speed for static HTML files.

Both Apache and Nginx support virtual hosting, which means you can host multiple websites or web applications on the same server. However, you will encounter situations in which you have an existing web server running, but a particular web application requires using a different web server. Port 80 or 443 on the public IP address can be used by only one process. If Apache is using the port, then Nginx can’t use (or bind to) it. So what can you do?

You can configure Nginx as a reverse proxy to Apache, so Nginx can redirect HTTP requests to Apache. In my experience, I found that this isn’t always the best way because it has once caused weird problems that I cannot troubleshoot. Instead, I prefer to use HAProxy as a reverse proxy for both Nginx and Apache. HAProxy is a free, open-source high availability load balancer and proxy server for TCP and HTTP-based applications.

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.

How to Block FLoC using Nginx, Apache, WordPress, HAProxy and more?

This is essentially a built-in Chrome browser itself and privacy concerned people can switch to another privacy concerned browser to avoid being tracked. But website owners can also opt-out of FLoC by making some simple modifications in their web server HTTP response header.

I would suggest checking out this Google and GitHub page to learn more about FLoC.

Python Packages in SQL Server – Get Started with SQL Server Machine Learning Services

Introduction

When installing Machine Learning Services in SQL Server by default few Python Packages are installed. In this article, we will have a look on how to get those installed python package information.

Python Packages

When we choose Python as Machine Learning Service during installation, the following packages are installed in SQL Server,

  • revoscalepy – This Microsoft Python package is used for remote compute contexts, streaming, parallel execution of rx functions for data import and transformation, modeling, visualization, and analysis.
  • microsoftml – This is another Microsoft Python package which adds machine learning algorithms in Python.
  • Anaconda 4.2 – Anaconda is an opensource Python package
