Addressing Mixed Content Errors on Sites Accessed via HTTPS



Mixed content takes place whenever initial HTML is loaded over a secure HTTPS connection while other resources (e.g. scripts, images, videos) are loaded over an unsecure HTTP connection. Due to the fact that the initial request was secure over HTTPS, and both HTTP and HTTPS need to be loaded to display the same page, this is deemed mixed content.

What the Edge Means for Developers



The ‘edge’ is dominating many conversations across the technology landscape today. 75% of enterprise-generated data will be created and processed outside of centralized cloud data centers and relocated to the edge by 2022, according to Gartner. However, beyond its potential for disrupting traditional cloud infrastructure, what does edge computing tactically mean for developers who are responsible for the day-in-day-out management of increasingly distributed web application architecture?

DevOps and Continuous Delivery at the Edge



To keep pace with technology, engineers must be able to conduct quick deployments in a safe, reliable and repeatable way. DevOps and continuous delivery (CD) help to support a more responsive and flexible, quicker time-to-market across the software delivery cycle; an increasingly important asset in a market in which IT departments are squeezed to achieve a quicker pace of innovation.

Why Load Balancing Is Critical to Web Performance



The two most important demands on any online service provider are availability and resiliency. It takes a server a certain amount of time to respond to any given request, depending on its current capacity. If during this process, a single component fails or the server is overwhelmed by requests, both the user and the business will suffer. Load balancing aims to solve this issue by sharing workloads across multiple components rather than using a single server, thereby ensuring consistently fast website performance at any scale.

Edge Computing is Paving the Way for 5G, IoT and AI



The growth of edge computing is not only creating opportunities for processing to take place closer to where data originates, but as more devices connect to the cloud via edge compute, it is also paving the way for further development of 5G, IoT and AI, thereby opening up virtually boundless possibilities in the future world of technology.

Vary User-Agent HTTP Response Header and its Effect in Varnish Cache



The HTTP response header “Vary: User-Agent” plays an important role in how your website cache works. When set correctly in Varnish Cache, it will ensure that your visitors see the correct content, regardless of whether caching is applied or not. If set up incorrectly, however, it can have a negative impact on the caching hit rate. If you want to improve your cache hit rate and user experience, it is worth considering, but be sure to use it with great care.

The Evolution of Cybersecurity in the Emerging Age of Edge Compute



Edge computing promises to improve efficiency when it comes to how data is gathered, processed and analyzed, but it also creates the potential for a whole new threat landscape. IoT devices are notorious for their security loopholes and as users rush to get ahead of the curve and implement compute at the edge, it is quickly becoming a new “front line” in the cybersecurity battle. At the same time, edge compute architecture offers new opportunities to implement more sophisticated security layers to protect against threats. As organizations try to stay ahead of the evolving technology paradigm, it is essential to build an appropriate edge cybersecurity strategy in response.

Diagnosing Latency Issues - Metrics, Logging, and Distributed Tracing



When using monitoring tools to identify latency issues, metrics and logging have their place, but they can be inadequate for offering true visibility across services, particularly with the rise of distributed application architectures. Distributed tracing, however, overcomes those challenges.

Hello from Matt



Today is the middle of my third week with section.io as a platform engineer, and it’s been a great ride so far! This is a company that lives on the bleeding edge of technology AND the internet that I’m very excited to join. I’ve worked on web technology from e-commerce to mobile applications, but this is the first time that I get to work full-time on a product that is targeted at other developers. I know we’re a tough and demanding audience, but I’m excited for the challenge and the opportunity to give back to the developer community by making the internet better! Going forward I’m going to be focusing on learning, delivering the most powerful edge platform available, and driving innovation for section.io!

The Case for Edge Computing Beyond IoT



The rise in the Internet of Things (IoT) is generally considered to be the leading driver for edge compute. By 2020, Gartner predicts there will be 20.4 billion ‘connected things’ in use around the world, up from 8.4 billion in 2017. There are many reasons why IoT is a natural fit for edge compute, ranging from the need for many IoT devices to be located in rural and remote areas that reside far away from traditional cloud data centers, to the challenges of meeting security and compliance requirements (especially in the GDPR era) when data is not processed on a local basis.
