What Are Namespaces and cgroups, and How Do They Work?

2021-07-22 KENNETH 0

What Are Namespaces and cgroups, and How Do They Work? p.quote { margin-left: 20px; font-style: italic; } Recently, I have been investigating NGINX Unit, our open source multi-language application server. As part of my investigation, I noticed that Unit supports both namespaces and cgroups, which enables process isolation. In this blog, we’ll look at these two major Linux technologies, which also underlie containers. Containers and associated tools like Docker and Kubernetes have been around for some time now. They have helped to change how software is developed and delivered in modern application environments. Containers make it possible to quickly deploy and run each piece of software in its own segregated environment, without the need to build individual virtual machines (VMs). Most people probably give little thought to how containers work under the covers, but I think it’s important to understand the [ more… ]

How to Manage Sudden Traffic Surges and Server Overload

How to Manage Sudden Traffic Surges and Server Overload For many retailers, the COVID‑19 pandemic changed where and how their customers shop for the holidays. Locked out of brick-and-mortar stores, shoppers flocked to online retailers more than ever before, spiking e‑commerce sales to $189 billion in 2020, a 33% increase over 2019. With fewer than six months standing between retailers and this year’s holiday shoppers, we’re revealing several ways you can leverage NGINX and prepare for sudden traffic spikes. Step 1: Know Where You Stand Against Your Competition Before making changes to your stack, it helps to know just how much you need to maximize your “Cyber Season” performance to thrive instead of just survive. Start by collecting data about the performance of competing websites. Time to load a page is probably the most important metric – many of today’s impatient users abandon a [ more… ]

Our Roadmap for QUIC and HTTP/3 Support in NGINX

2021-07-13 KENNETH 0

Our Roadmap for QUIC and HTTP/3 Support in NGINX The Internet refuses to stand still. Even before the standardization of HTTP/2 in 2015, work had already begun on QUIC and what would later become HTTP/3. Now, five years since the first draft specification for QUIC was submitted to the IETF, we have RFC 9000, QUIC: A UDP‑Based Multiplexed and Secure Transport. Of course, it’s not quite that simple. At the time of writing, a total of four RFCs have been published that describe the core QUIC transport and encryption layer. A further eleven related specifications remain in draft, including the final definition of HTTP/3. However, many client and server implementations are already in widespread use. In fact, 20% of all websites already support HTTP/3 thanks to the efforts of CDN providers and tech giants who have been keeping pace with the draft standards. [ more… ]
