This Week in Website Performance is a new weekly feature of the Monitis blog. It used to be featured on the Monitor.Us blog, but we decided to share this awesome compilation of website performance articles with our readers at Monitis as well. It summarizes recent articles about website performance. You can check out the Monitor.Us weekly articles archives here.
There is an abundance of metrics that can be monitored, and selecting an efficient subset to utilise is a science. This article from Monitis describes how they use the mathematical procedure Principal Component Analysis to select a set of key metrics for effective monitoring.

mod_pagespeed is an open source Apache module designed to automate all of the popular web performance best practices: minification, inlining, spriting, image optimization, concatenating files, sharding, and the list goes on. mod_pagespeed installs an output filter which detects and stream-parses HTML content. Output rewriting can use a variety of filters, from removing whitespace to compressing images, in order to improve optimisation of delivered URL assets.

Although performance optimization usually leads to performance improvement, they are not the same. Performance improvement is the art and science of making online applications faster, while performance optimization is the art and science of making online applications efficient. Using the homepage of a high-end specialty retailer, this article will show the results of focused performance optimization.

As-a-service models offer huge opportunities, but also complicate security. It may seem that the easiest way to migrate to a new architectural model is to let others, experts in their field, do the work. This has given rise to many as-a-service models throughout the industry and across the entire technology stack, from software to infrastructure. While this has unlocked huge opportunities to accelerate the deployment of new capabilities or increase economic efficiencies within an organization, i...

The web app is agile. The REST API is agile. The testing and planning are agile. But alas, data infrastructures certainly are not. Once an application matures, changing the shape or indexing scheme of data often forces at best a top down planning exercise and at worst includes schema changes that force downtime. The time has come for a new approach that fundamentally advances the agility of distributed data infrastructures. Come learn about a new solution to the problems faced by software organ...

Overgrown applications have given way to modular applications, driven by the need to break larger problems into smaller problems. Similarly large monolithic development processes have been forced to be broken into smaller agile development cycles. Looking at trends in software development, microservices architectures meet the same demands. Additional benefits of microservices architectures are compartmentalization and a limited impact of service failure versus a complete software malfunction....

The last decade was about virtual machines, but the next one is about containers. Containers enable a service to run on any host at any time. Traditional tools are starting to show cracks because they were not designed for this level of application portability. Now is the time to look at new ways to deploy and manage applications at scale. In his session at @DevOpsSummit, Brian “Redbeard” Harrington, a principal architect at CoreOS, will examine how CoreOS helps teams run in production. Attende...

Developing software for the Internet of Things (IoT) comes with its own set of challenges. Security, privacy, and unified standards are a few key issues. In addition, each IoT product is comprised of at least three separate application components: the software embedded in the device, the backend big-data service, and the mobile application for the end user's controls. Each component is developed by a different team, using different technologies and practices, and deployed to a different stack/...
