The document discusses Varnish, an open source HTTP accelerator. It provides an overview of caching and why it is useful, explaining how Varnish can be used as a reverse proxy and caching layer in front of a web server. The document then covers setup instructions for Varnish, configuring backends, and using Varnishstat to monitor caching statistics and performance metrics.
Varnish is an HTTP accelerator that can be used as a reverse proxy, caching proxy, or load balancer to speed up websites. It works by caching computed data and storing responses for faster serving of future requests. Using a caching proxy like Varnish solves problems with browser caches, provides a single cache, and protects servers from overload by serving cached content. The document provides instructions on setting up Varnish, configuring a backend server, and using the varnishstat tool to view caching statistics and hit rates.
Thijs Feryn will give a presentation on using Varnish as an HTTP accelerator and caching proxy at the PHP Barcelona Conference on October 29, 2010. He discusses how Varnish can be used to cache content, protect servers from overload, and improve site performance through caching, hitting ratios of over 50% on average.
Varnish is an HTTP accelerator that acts as a reverse proxy and cache. It is very fast due to being open source and outsourcing tasks to kernel functions. It relies on a massively multithreaded architecture that is partly event driven. It maps the cache store into memory using mmap and writes directly from mapped memory for maximum performance. Logging includes all request headers. Wikia uses Varnish across 4 datacenters with rapid cache invalidations and a RabbitMQ queue to handle invalidations. SSDs and tuning help optimize performance.

Java на Linux встречается повсеместно в информационных системах от больших данных до новомодных serverless архитектур. Как Linux, так и Java имеют свои эксплуатационные нюансы. Понимание этих нюансов важно, чтобы заставить стек Java + Linux работать стабильно и эффективно.
Но на практике "джависты" очень любят мыслить кроссплатформенно и не хотят разбираться с особенностями операционной системы, a "линускоиды" считают JVM чуждым миру Linux процессом, пожирающим всю доступную на сервере память.
А потом появляется Docker, и нюансов становится ещё больше...
Цель доклада - рассказать "джавистам" про Linux и Docker, а "линуксоидам" про JVM.
ok.ru is one of top 10 internet sites of the World, according to similarweb.com. Under the hood, it has several thousand servers. Each of those servers own only fraction of the data or business logic. Shared nothing architecture can be hardly applied to social network, due to its nature, so a lot of communication happens between these servers, diverse in kind and volume. This makes ok.ru one of the largest, complicated, yet highly loaded distributed systems in the world.
This talk is about our experience in building always available, resilient to failures distributed systems in Java, their basic and not so basic failure and recovery scenarios, methods of failure testing and diagnostics. We’ll also discuss on possible disasters and how to prevent or get over them.
This document summarizes a presentation about the WiredTiger In-Memory storage engine for MongoDB compared to the standard WiredTiger B-Tree storage engine. The Percona Memory Engine can provide up to 1000 times faster performance for OLTP workloads and 10 times faster reads compared to WiredTiger by storing data entirely in memory instead of on disk. It uses WiredTiger's document-level locking and B-Tree structure but without disk access. Typical use cases for the in-memory engine include caching, session storage, and temporary collections. The presentation provides examples of how to configure and optimize the engine for different scenarios including replica sets, sharded clusters, and combining it with WiredTiger for persistence.
Caching and tuning fun for high scalabilityWim Godden
Caching has been a 'hot' topic for a few years. But caching takes more than merely taking data and putting it in a cache : the right caching techniques can improve performance and reduce load significantly. But we'll also look at some major pitfalls, showing that caching the wrong way can bring down your site. If you're looking for a clear explanation about various caching techniques and tools like Memcached, Nginx and Varnish, as well as ways to deploy them in an efficient way, this talk is for you.

Add a bit of ACID to Cassandra. Cassandra Summit EU 2014odnoklassniki.ru
OK.ru is one of the largest social networks for Russian-speaking audiences with 80+ million unique user’s visits monthly. ok.ru uses Cassandra since 2010 and made a number of improvements to C* 2.0 and 2.1 codebase. Until recent time more than 50 TB of data at Ok.ru OLTP systems was managed by Microsoft SQL Sever. It’s very expensive, hard to scale and cannot save us from outage if one of our data centers fail. We wanted a new, fast scalable and reliable storage for these data. These data has requirements to support ACID transactions, so we don’t have to rewrite all application code from scratch. С* does not support these transactions, only lightweight, so we implemented a new storage with ACID and selected features of SQL world by ourselves. Still, it has C* at its heart. We’ll discuss the internals of the new storage, what features of C* we had to alter and which to rewrite from scratch. We’ll also talk about its operational experience in production.
Matteo Collina | Take your HTTP server to Ludicrous Speed | Codmeotion Madrid...Codemotion
In my journey through nodeland, I always wonder about the cost of my abstractions. Express, Hapi, Restify, or just plain Node.js core? require(‘http’) can reach 30k requests/sec, Express 22k, and Hapi 21k. I started a journey to write an HTTP framework with extremely low overhead, and Fastify was born. With its ability to reach an astonishing 37k requests/sec, Fastify can halve your cloud server bill. How can Fastify be so.. fast? We will discover all the not-so-secret techniques that were used to optimize it. In Fastify we reach a point where even allocating a callback is too slow: Ludicrous
The document discusses slowdowns, hangs, and thread dumps in troubleshooting Java applications.

Emotional intelligence is key to effective leadership. Leaders must manage their own emotions to avoid relationship problems, rage in the workplace, poor decision making, and high employee turnover. Developing emotional intelligence allows leaders to have personal mastery, build empathy, influence others, solve conflicts, make good decisions under pressure, and drive vision and performance. Leaders can improve emotional intelligence by paying attention to body language, listening more than speaking, reframing negative emotions into curiosity, eliciting pride in others, and being aware that emotions are contagious. Regularly checking in on factors like work-life balance, feedback, productivity, motivation, and purpose within their team can help leaders build a strong emotionally intelligent team.

The year is about to end, and I didn't publish reports about checks of open-source projects for a long time. Programmers asked me to check PostgreSQL Database Management System many times, and I've finally decided to do it. Unfortunately, this article isn't going to be large and interesting, as I found just a few typical bugs in the project. So, the report is pretty short this time.
Varnish is an HTTP accelerator designed for content-heavy dynamic web sites and APIs. It operates primarily based on HTTP headers to cache web content. Varnish offers more flexibility than Squid for rewriting URLs and supporting SSL natively. It has better performance and scalability than Squid as it uses multiple threads. The key components of Varnish include the management process, child process, and storage backends like file and malloc. Common Varnish calls in VCL include pass, lookup, pipe and deliver. Varnish caching behavior is configured in default.vcl using functions like vcl_recv, vcl_hash, vcl_hit and vcl_miss.

PHP London Dec 2013 - Varnish - The 9 circles of hellluis-ferro
Varnish is an HTTP accelerator. Its use will allow you to server more content/requests with the same or even less hardware. But with all good things, for each use,the complexity of your solution will increase.
On this talk, I will show how to use Varnish to implement some advanced cache solutions like adding GeoIP processing on varnish and ESI (Edge Side Includes).
In-depth caching in Varnish - GOG Varnish Meetup, march 2019GOG.com dev team
You think Varnish can cache responses by URL only? Not even close. Learn all different caching strategies available in Varnish, their benefits and consequences of usage. Learn how to and when to queue requests for the same endpoint, how to handle requests with conditional caching headers and how to have two levels of cache by tagging the responses.
The document discusses cache concepts and the Varnish caching software. It provides an agenda that covers cache concepts like levels and types of caches as well as HTTP headers that help caching. It then covers Varnish, describing it as an HTTP accelerator, and discusses its process architecture, installation, basic configuration using VCL, backends, probes, directors, functions/subroutines, and tuning best practices.
Warewulf 4.3.0 is an open source, stateless operating system provisioning system that is lightweight, flexible, and container-based. It uses containers to define the base OS for nodes and overlays to customize configurations on a per-node basis using templates. Nodes boot using PXE and iPXE to load the kernel, container, and system overlay before contacting the warewulfd server to retrieve the runtime overlay and complete booting into the container OS in a stateless manner. Future plans include adding new APIs and additional management features.
This document discusses using varnishlog to debug VCL code that is not behaving as expected. It provides examples of how to use varnishlog to investigate 500 responses, misses, timing details, and requests over 5 seconds. It also discusses timestamps in varnishlog output and how they can help debug timing issues. Examples are given for reproducing issues using varnishtest. The document encourages reaching out for support and exploring panic dumps and core files if Varnish crashes.
Varnish is a modern, open source HTTP accelerator that provides fast, efficient web caching. It is state-of-the-art, scales well in high traffic environments, and is used by many top websites.

Caching and tuning fun for high scalability @ FOSDEM 2012Wim Godden
Caching has been a 'hot' topic for a few years. But caching takes more than merely taking data and putting it in a cache : the right caching techniques can improve performance and reduce load significantly. But we'll also look at some major pitfalls, showing that caching the wrong way can bring down your site. If you're looking for a clear explanation about various caching techniques and tools like Memcached, Nginx and Varnish, as well as ways to deploy them in an efficient way, this talk is for you.

The presentation aims to provide web developers with random notes to help make the most of Varnish Cache Plus beyond just caching policies.
Don't expect anything epic from this article. We have checked the Bitcoin project's source code with PVS-Studio and found just a couple of suspicious fragments. Which is no wonder: I guess there are few programmers who haven't checked it already. But since we have done our check too, we need to write a small post about it, pro forma, so to say.
The root cause was a process getting a DLM EX lock on an inode and then trying to get a DLM PR lock on the same inode, causing a deadlock. Kernel patches were identified to avoid recursive locking and fix the deadlock. The patches were tested, added to the SUSE kernel source repository, and a PTF rpm was created and tested by the customer to resolve the issue.
The author checked header files from Embarcadero C++Builder XE3 and found several errors, including issues with macros not using curly brackets properly, undefined behavior from bit shifting, and checking for null pointers after memory allocation (which is unnecessary since exceptions will be thrown). Many of these types of errors were found in inline functions. The conclusion recommends the C++Builder developers look into these findings to improve the quality of the compiler and libraries.
Varnish is an HTTP proxy and cache designed for high-performance web applications. It has a key-value store architecture and is written in C for performance. Varnish uses Varnish Configuration Language (VCL) scripts to control caching and backend configuration. It has a multithreaded design with worker processes that handle client connections and caching of responses from backend servers. Administrators can use tools like varnishstat, varnishlog, and varnishadm to monitor caches, view logs, and control the Varnish instance.
Play it extra safe! Kies een goede cyberverzekeringCombell NV
Bij Combell zorgen we voor de beste beveiliging tegen hackers en andere cyberaanvallen. Helaas is 100% waterdichte beveiliging een utopie. We ijveren altijd voor de beste voorzorgen en set-ups. Maar er zijn altijd nieuwe technieken, bugs of lekken.
Als je business – in meerdere of mindere mate - afhangt van IT om te blijven draaien, dan is zelfs de beste security niet voldoende. Een onderbreking kan een té groot prijskaartje met zich mee brengen. Net daarvoor zijn er cyberverzekeringen, zij dekken de geleden schade als er toch iets voorvalt.
Hoe werkt zo’n cyber insurance? Waar ben je dan precies tegen verzekerd en hoe kies je een goede polis? De experten van Vanbreda Risk & Benefits brengen de aandachtspunten aan het licht. Je zal versteld staan van de mogelijke scenario’s!

Managed WordPress bij Combell – wat doet dat precies?Combell NV
WordPress is terecht uitgegroeid tot het populairste CMS dankzij zijn gebruiksvriendelijkheid. Maar hoe gebruiksvriendelijk WordPress ook is, er zijn nog altijd dingen die je zelf moet doen - de nieuwste beveiligingsupdates uitvoeren bijvoorbeeld. Dat vormt voor veel mensen toch een hinderpaal.

Back-ups: Hoe ze je kunnen redden van een cyberaanvalCombell NV
Het aantal cyberaanvallen stijgt jaar na jaar en ook de methoden die cybercriminelen gebruiken worden beter. Maar één ding is belangrijk om te blijven onthouden: 100% veiligheid bestaat niet. Er is altijd wel een stukje software met een lek of een onbeveiligd apparaat dat cybercriminelen de kans geeft in te breken in je omgeving. En ook menselijke fouten kunnen je waardevolle informatie doen kwijtspelen.
Nadenken over de manier waarop je omgaat met back-ups is dus cruciaal. De beste back-up strategie is echter sterk afhankelijk van je bedrijf en je data. Het vereist een planning waarbij je goed nadenkt over welke keuzes het best zijn voor jouw onderneming.
Kies je bijvoorbeeld voor een lokale opslag of toch eerder voor de cloud? Of allebei?
Een back-up op een andere locatie (off-site) is soms het enige wat uit de handen van hackers kan blijven. Zeker wanneer je bedrijfsvoering afhangt van automatische processen is dit een niet te verwaarlozen onderdeel van je back-up strategie.
