Introduction

In today’s fast-paced digital landscape, ensuring the availability and performance of applications is paramount. Modern infrastructures require robust solutions to distribute traffic efficiently and maintain service availability even in the face of server failures. Enter HAProxy, the de facto standard for high-performance load balancing and failover.

This article explores the synergy between HAProxy and Ubuntu, one of the most popular Linux distributions. From installation to advanced configuration, we’ll dive into how HAProxy can transform your infrastructure with load balancing and failover capabilities.

Understanding Load Balancing

Load balancing is the process of distributing incoming network traffic across multiple servers. By balancing the load, it ensures no single server becomes overwhelmed, leading to better performance, reliability, and fault tolerance.

Key benefits

• Scalability: Ability to handle increasing traffic by adding more servers.
• Reliability: Mitigating server failures by routing traffic to healthy servers.
• Performance: Reducing latency by spreading the workload evenly.

Types of load balancing

• Layer 4 (Transport Layer): Distributes traffic based on IP and port information.
• Layer 7 (Application Layer): Makes routing decisions based on application-level data such as HTTP headers.

Failover Concepts

Failover ensures continuity by automatically redirecting traffic to backup resources if the primary ones fail. It’s a cornerstone of High Availability (HA) setups.

With HAProxy, failover is seamless:

• If a backend server becomes unavailable, HAProxy detects it via health checks.
• Traffic is rerouted to other available servers, maintaining uninterrupted service.

Setting Up HAProxy on Ubuntu

Let’s begin by installing and configuring HAProxy on Ubuntu.

Prerequisites

• An Ubuntu server (20.04 or later recommended).
• Multiple backend servers for testing load balancing.
• Basic Linux command-line skills.

Step 1: Installing HAProxy

1. Update your system:

   sudo apt update && sudo apt upgrade -y

2. Install HAProxy:

   sudo apt install haproxy -y

3. Verify installation:

   haproxy -v

Linux Kernel 6.12 Has Been Released

Source: https://linux.slashdot.org/story/24/11/18/0142252/linux-kernel-612-has-been-released?utm_source=atom1.0mainlinkanon&utm_medium=feed

Slashdot unixbhaskar writes: Linus has released a fresh Linux kernel for public consumption. Please give it a try and report any glitches to the maintainers for improvement. Also, please do not forget to express your appreciation to those tireless folks who did all the hard work for you. The blog OMG Ubuntu calls it "one of the most biggest kernel releases for a while," joking that it's a "really real-time kernel." The headline feature in Linux 6.12 is mainline support for PREEMPT_RT. This patch set dramatically improves the performance of real-time applications by making kernel processes pre-emptible — effectively enabled proper real-time computing... Meanwhile, Linus Torvalds himself contributes a new method for user-space address masking designed to claw back some of the performance lost due to Spectre-v1 mitigations. You might have heard that kernel devs have been working to add QR error codes to Linux's kernel panic BSOD screen (as a waterfall of error text is often cut off and not easily copied for ad-hoc debugging). Well, Linux 6.12 adds support for those during Direct Rendering Manager panics... A slew of new RISC-V CPU ISA extensions are supported in Linux 6.12; hybrid CPU scaling in the Intel P-State driver lands ahead of upcoming Intel Core Ultra 2000 chips; and AMD P-State driver improves AMD Boost and AMD Preferred Core features. More coverage from the blog 9to5Linux highlights a new scheduler called sched_ext, Clang support (including LTO) for nolibc, support for NVIDIA's virtual command queue implementation for SMMUv3, and "an updated cpuidle tool that now displays the residency value of cpuidle states for a clearer and more detailed view of idle state information when using cpuidle-info." Linux kernel 6.12 also introduces SWIG bindings for libcpupower to make it easier for developers to write scripts that use and extend the functionality of libcpupower, support for translating normalized error addresses reported by an AMD memory controller into system physical addresses using a UEFI mechanism called platform runtime mechanism (PRM), as well as simplified loading of microcode patches on AMD Zen and newer CPUs by using the family, model, and stepping encoded in the patch revision number... Moreover, Linux 6.12 adds support for running as a protected guest on Android as well as perf and support for a bunch of new interconnect PMUs. It also adds the final conversions to the new Intel VFM CPU model matching macros, rewrites the PCM buffer allocation handling and locking optimizations, and improves the USB audio driver...

'Automotive Grade Linux' Will Promote Open Source Program Offices for Automakers

Posted: 2024-11-16 18:34:00
Source: https://tech.slashdot.org/story/24/11/16/0659221/automotive-grade-linux-will-promote-open-source-program-offices-for-automakers?utm_source=atom1.0mainlinkanon&utm_medium=feed

Automotive Grade Linux is a collaborative open source project developing "an open platform from the ground up that can serve as the de facto industry standard" for fast development of new features. Automakers have joined with tech companies and suppliers to speed up development (and adoption) of "a fully open software stack for the connected car" — hosted at the Linux Foundation, and "with Linux at its core..." And this week they created a new Open Source Program Office expert group, led by Toyota, to promote the establishment of Open Source Program Offices within the automotive industry, "and encourage the sharing of information and best practices between them." Open source software has become more prevalent across the automotive industry as automakers invest more time and resources into software development. Automakers like Toyota and Subaru are using open source software for infotainment and instrument cluster applications. Other open source applications across the automotive industry include R&D, testing, vehicle-to-cloud and fleet management. "Historically, there has been little code contributed back to the open source community," said Dan Cauchy, Executive Director of Automotive Grade Linux. "Often, this was because the internal procedures or IT infrastructure weren't in place to support open source contributions. The rise of software-defined vehicles has led to a growing trend of automakers not just using, but also contributing, to open source software. Many organizations are also establishing Open Source Program Offices to streamline and organize open source activities to better support business goals." Automakers including Toyota, Honda, and Volvo have already established Open Source Program Offices. The new AGL OSPO Expert Group provides a neutral space for them to share pain points and collaborate on solutions, exchange information, and develop best practices that can help other automakers build their own OSPOs. "Toyota has been participating in AGL and the broader open source community for over a decade," said Masato Endo, Group Manager of Open Source Program Group, Toyota. "We established an OSPO earlier this year to promote the use of open source software internally and to help guide how and where we contribute. We are looking forward to working with other open source leaders to solve common problems, collaborate on best practices, and invigorate open source activities in the automotive industry." The AGL OSPO EG is led by Toyota with support from Panasonic and AISIN Corporation.
