The speed at which you can go from making a change in your code, to understanding if it actually works, has long been a popular topic of discussion (and often, humour) for engineers. This remains true in a world with AI. Developer experience isn't just important for humans anymore. Those agents we're all using hundreds of times a day? Feedback cycles matter just as much for them, if not more.

This blog post is based on a product presentation by Antonis Kalipetis, Staff Engineer at SymfonyCon 2023, about Upsun's experience with Nix. We utilized ChatGPT for transcription and to enhance the grammar and syntax. Django deployments have evolved since the framework's early days.

“Every engineering decision is a cost decision,” notes Ben Johnson, co-founder and CTO of Obsidian Security. That’s the reality of building modern SaaS products in the cloud. But as Ben points out, the answer isn’t to make engineers think long and hard about every dollar they spend. “You don’t want your team hesitating to solve risky technical problems because a choice might add $100 to the bill.

This fall and winter have had their share of major outages (including AWS, Azure, and Cloudflare), and December was no exception. On December 5, 2025, Cloudflare suffered a 25-minute outage that served responses with HTTP 500 errors to about 28% of HTTP traffic served by Cloudflare. Since Cloudflare handles an average of 81 million HTTP requests per second, this represents a substantial chunk of internet traffic, including LinkedIn, Zoom, and Downdetector.

Outgrowing Heroku? Stop the manual DevOps grind. Migrate to AWS in <7 days using AI to generate Terraform, EKS configs, and a seamless developer experience.

Security used to be something teams added at the end of a release cycle. Engineering pushed code fast. Security teams reviewed it later. But this flow only worked when the software moved slowly. Modern cloud environments broke the old security model. Containers, microservices, APIs, and infrastructure as code now change too fast for security to sit outside delivery workflows.

Every time I step on set with a guest for FinOps In Full Bloom, I’m anticipating the lightbulb moments I know will pop up during the podcast. These are the conversations that reveal how curiosity and collaboration can spark real transformation in the cloud.

This blog post is based on Florent Huck, Developer Advocate at Upsun, at SymfonyCon 2023. We utilized AI tools for transcription and to enhance the structure and clarity of the content. The journey from a single monolithic application to a multi-application architecture doesn't have to be daunting. At a recent developer conference, Florent from Upsun's Developer Relations team shared a practical step-by-step guide on how to refactor a monolith into multiple applications using Upsun.
