Continuing the 'Architecting for the Cloud, one pattern at a time' series, Chris and Peter Piper explore two closely related cloud design patterns for securing APIs and backend resources. The Gatekeeper pattern positions a dedicated host between untrusted clients and trusted backend services — handling authentication, authorization, request validation, protocol translation, and rate limiting. The Valet Key pattern complements it by issuing short-lived, scope-restricted tokens (such as Azure SAS tokens) so clients can access specific resources directly, reducing load on central services without sacrificing security. The episode covers practical implementation options on Azure including API Management, Azure Key Vault, and Azure App Configuration.

When I mention the term JAMStack, I'm not pretending that I'm Paddington bear with a stack of Jam sandwiches! If you hadn't heard, JAMStack is a term that describes applications based on JavaScript, APIs and Markup. That means, we're referring to files that are content in nature. Think about files like HTML, CSS, Images, etc. Ok, now with that context - why has it risen in popularity? Surely this is something that could have been done for many years, so why now? My hypothesis... Cloud.

Chris announces his involvement with relaunching the Azure Thames Valley meetup, recaps the static content hosting pattern episode and his open source blog, and previews upcoming talks at AzureIsh Live and a SquaredUp webinar on application observability with Azure Monitor and App Insights. He covers Azure Updates including public IP SKU upgrades, built-in Azure Policy for NSG flow logs, GitHub's availability in Iran, the GitHub Enterprise Server 3.0 release candidate, and Docker Desktop integration with Azure Container Instances.

Serving static HTML, CSS, images, and JavaScript from a general-purpose web server wastes compute and money. The Static Content Hosting pattern offloads these assets to cloud storage—Azure Blob Storage, AWS S3, or GCP Storage—optionally fronted by a CDN for global performance and storage-tier scalability. This episode walks through the pattern, a real-world implementation with Hugo and Azure CDN, and the trade-offs to consider.

Contributing to Open Source Software. It sounds so formal, doesn't it? I thought that for quite a long time, and it put a bit of a mental barrier in place for me to begin my journey. I am a classic over thinker, but that's perhaps another blog in its own right! Contributing to Open Source isn't as scary as it may first initially seem. Let's start with a few thoughts.

Chris covers channel updates for Cloud with Chris, including a new video on GitHub Codespaces and a blog series on open source contributions to Hugo themes. He highlights the Azure Updates RSS feed as an essential resource for tracking Azure service changes, and spotlights community contributors JonnyChipz, Sarah Lean (TechieLass), CloudFamily.info, and Richard Hooper (PixelRobots).

Setting up a development environment—installing the right SDK versions, extensions, and tools—wastes hours and causes 'works on my machine' problems. This episode shows how VS Code's Remote Containers extension and GitHub Codespaces solve this with containerised, reproducible dev environments defined in a devcontainer.json file. See a live demo of editing cloudwithchris.com entirely in a browser-based Codespace.

During the 2020 Festive Break, I had a lot of time on my hands. I took 4 weeks of my Annual Leave, which meant I had the majority of December to personal time. Personal time / time off is great, but I also wanted to push myself and catch up on some pieces that were on my personal learning or achievement list for some time. I started refreshing my knowledge around Rails (having developed in it some years ago, it's progressed quite a bit!), NodeJS, GoLang and Rust. All interesting to learn, and I'm sure I'll be continuing on my journey with these throughout 2021. But that's not the point in this blog post. One of the activities that I kicked off was contributing into the Hugo Community. Read on to find out more.

Chris launches the weekly vlog format with a recap of December 2020, including open source contributions to the Hugo Castanet theme and the start of a new community-focused Hugo theme project. He reviews Azure updates covering Azure Synapse Analytics GA and Microsoft BGP routing security improvements, highlights GitHub's DevSecOps tooling with CodeQL and Dependabot, and explains the new Azure DevOps service tag for network security groups.

You may have noticed there are some posts preceding this one. I've had a few attempts at putting my blog together, but then dwindle out on my cadence... Well, given the recent success with my Cloud with Chris podcast, I'm beginning to consolidate... Starting with my blog! Here's an update on what you have to look forward to!
