In case you haven’t noticed, video marketing is on fire right now with compelling statistics around this trend hard to ignore. And for good reason — everyone from large enterprises and educational institutions to community groups and entrepreneurs are incorporating richer content into their websites, such as images and videos. Hence, the importance of choosing a high-quality content delivery network (CDN) provider.

Contextual Code specializes in enterprise-level projects for state government agencies. We routinely tackle difficult web content management implementations, migrations, integrations, customizations, and operations. We know what it takes to get a project off the ground and onto the web. We use Upsun as our primary hosting platform because it’s incredibly flexible and it provides a vast list of services that can be set up very easily.

AWS offers a Compute Optimizer tool that uses machine learning to analyze your historical utilization metrics and then recommend optimal AWS resources to help you reduce costs and improve performance. And it is free, you just need to opt in to the service in the AWS Compute Optimizer Console. Sounds great, right? Well, yes and no. It is a useful little tool, but if you do not understand its pros and cons, you will not be as optimized as you may think. Here is a breakdown.

According to AWS, “Creating a software system is a lot like constructing a building. If the foundation is not solid, structural problems can undermine the integrity and function of the building.” This is especially true when it comes to the cloud. If an organization doesn’t effectively oversee key areas of its foundation, it’s likely the result is not going to be successful. When it comes to cloud management, we look at it through the lens of the AWS Well-Architected Framework.

I worked at Google for six years. Internally, you have no choice — you must use Kubernetes if you are deploying microservices and containers (it’s actually not called Kubernetes inside of Google, it’s called Borg). But what was once solely an internal project at Google has since been open-sourced, and has become one of the most talked-about technologies in software development and operations.

Most interactions with a web application occur at the browser. Users search items, fill forms, create shopping carts, log into their profiles, and perform many other tasks. Unit tests are great, but nothing beats testing an application by interacting with the user-facing frontend. In this tutorial, you will learn and demonstrate how to write tests for the browser using Puppeteer . You will then take this a step further by automating the testing process in a continuous integration flow.

Maximizing spectrum efficiency is a challenge that operators have wrestled with for decades. And the challenge of optimizing spectrum planning and management is only magnified as networks become faster and more complex. Operators with a well thought-out plan can avoid significant waste and inefficiency in the network. Wavelength division multiplexing was originally constrained to a fixed grid, first at channel widths of 100GHz, and then, as lasers improved, at 50GHz.
