Varnish HTTP Cache Control with Improved SSL/TLS Management for Web Servers
Varnish Cache is used by over 2.5 million websites in production in 2018, including by some of the largest IT & media corporations like Twitter, NYT, Wikipedia, Guardian.uk, Facebook, & Vimeo. Varnish Cache is a reverse-proxy HTTP cloud load balancing software that can speed up website content delivery to browsers through page load request processing on the same hardware by 300 to 1000 times. Varnish Cache accomplishes these web server performance improvements through better repeat request file caching on network I/O transfers, where Hitch can be used for more efficient encryption connection management & control at scale for web servers running under https with SSL/TLS certificates. Varnish Cache supports Apache & NGINX web servers and installs on either Linux (Ubuntu, Debian, RHEL, & CentOS) or FreeBSD to operate. Drupal, WordPress, Magento, and other CMS website publishers can directly integrate Varnish Cache with their web page content management system and secure better performance with support for web traffic on hardware in the ongoing maintenance of cloud apps for business, government, or media organizations. Varnish Cache has open source versions, cloud licensed, and enterprise licensed products available depending on the web hosting traffic volume or data center size.

Varnish Cache is developed by a company based in Oslo, Norway. The platform software dates to 2004-2005. Varnish Massive Storage Engine (VMSE) allows the largest size corporations or complex organizations to manage their web publishing, customer management, ecommerce archives, databases, etc. in a unified suite of tools to improve efficiency or portability in cloud orchestration. The ability to deploy on a proven & tested framework saves significant costs over in-house software development as well as launching quicker as a solution. The popularity of Varnish Cache software is based on independent benchmarking where the best performing web servers for CMS hosting run NGINX with Varnish Cache for multi-layered caching advantages.
Varnish is a reverse HTTP proxy, sometimes referred to as an HTTP accelerator or a web accelerator. A reverse proxy is a proxy server that appears to clients as an ordinary server. Varnish stores (caches) files or fragments of files in memory that are used to reduce the response time and network bandwidth consumption on future, equivalent requests. Varnish is designed for modern hardware, modern operating systems and modern work loads. Varnish is more than a reverse HTTP proxy that caches content to speed up your server.
Varnish Cache takes advantage of 64-bit multi-processing as well as offering the VCL programming language for compatibility with applications written in C. Cached objects are stored in the HTTP cache with URL linked dependencies. Cloud load balancing optimizes network traffic vs. available hardware, HTTP cache, & CDN resources. Fitch and other tools can be used to manage the TLS encryption standards for https connections. VMSE is optimal for enterprise-scale "big data" management, web hosting company data centers, or public cloud orchestration requiring advanced database & file transfer tools. The Varnish DIY CDN integration is optimized to work with Varnish Cache solutions for best performance in web page download speeds in production, including database response times, programming language support, I/O request processing, PHP/Python/Node.js functions, etc. as required by advanced web/mobile SaaS apps. Major companies like Tesla use Varnish Software to custom build CDN deployments for their website hosting support requirements internationally.
NGINX & Zookeeper:
Deployment strategies are a large focus for a lot of teams right now as more and more companies begin to migrate services to public cloud. All of these teams have one goal in common, Zero Downtime. The most common strategy for this is the Blue Green Deployment... In this talk we will explore a case study around moving a large stack of over 30 application to Amazon Web Services and why Nginx was the right choice for load balancing and the deployment. The Goal, release code without dropping a single packet and ensure all applications get their new code version at the exact same time. With the use of Zookeeper for service discovery, new nodes in the environment are automatically added to Nginx upstream pools. When new code is released and applications nodes ready, Nginx is alerted and directs traffic to new pools serving the latest release.
Varnish Cache Hitch addresses the problem that websites and mobile apps in production need better resource management for TLS connections on hardware at scale. This includes better termination and clean-up sweeps by automated system scans that improve resource utilization on data center plans. Hitch will allow website administrators to configure SSL/TLS certificates to provide web encryption on data transmissions across an application's service footprint. Web acceleration provides analytic software for data center networks with improved HTTP/S file caching on user requests that can boost hardware performance to higher levels of efficiency. API services can use Varnish Cache in production to optimize response times and improve processing for data streams & pipelines. Varnish Cache is considered a "quick fix" to improving a quickly scaling website or popular blog's production issues or for optimizing the highest rates of data center traffic for web hosting. The most advanced projects can build in Varnish Configuration Language (VCL) to create new solutions that optimize data center hardware for cloud web publishing requirements.
The Varnish DIY CDN allows administrators to choose the particular data center locations internationally they wish to launch to and support with disk plans, or to auto-scale to all locations with cloud load balancing and save millions on data center fees for web hosting. Other alternatives are building with a major cloud CDN from Google, AWS, Akamai, etc. to support Varnish Cache installations in production at scale. It is common for WordPress and Drupal specialist hosting companies to install Varnish Cache across their platform stack for cloud support, where other SaaS companies manage hardware through container virtualization and Kubernetes orchestration or use AWS EC2. Redis provides database cache and message brokering utilities that may further improve NGINX & Varnish Cache web server deployments for even better performance in hosting web/mobile apps at high rates of user traffic. The change from Linux servers to BSD servers, also seen with LiteSpeed, has been considered as an option in some high volume support environments using Varnish Cache optimization.
NGINX & Varnish Cache:
Varnish Cache is a web application accelerator also known as a caching HTTP reverse proxy. You install it in front of any server that speaks HTTP and configure it to cache the contents. Varnish Cache is really, really fast. It typically speeds up delivery with a factor of 300 - 1000x, depending on your architecture.
Overall, Varnish Cache is leading the industry in HTTP/S reverse proxy cache efficiency for cloud web servers in production to support complex web/mobile apps and CMS sites.
