You push a branch. If your team is like most, that branch now waits: for the shared staging server to free up, for someone to remember to refresh the seed data, for whoever broke staging last to fix it. By the time you actually test your change, you're testing it in an environment that's drifted from production in ways nobody fully tracked. The alternative isn't a better staging server. It doesn't need one.

Infrastructure for AI agents usually forces a choice between two bad options. A sandbox is safe but blind, cut off from the data and services that would make the agent's output useful. Full access means paying to keep a container idle between runs, waiting on a prompt that might not arrive for hours. Task containers, which Upsun released on August 12, 2026, are built to avoid that choice. A task container is a single-purpose container defined in a project's.upsun/config.yaml file.

When you choose a cloud platform, you're entrusting a provider with sensitive business information, customer data, critical applications, and a growing share of your operational resilience. Increasingly, you are also entrusting it with AI. And that changes the questions you should be asking. Marketing claims cannot answer these questions. Independent evidence can. Here is what that evidence looks like at Upsun and why it matters to your next supplier review.

You wrote the feature. It works locally. Then you spend the next two hours on things that have nothing to do with the feature: a Terraform plan that wants to replace a database you didn't touch, a Kubernetes manifest that needs a new ingress rule, an IAM policy that's one permission short of what the deploy needs. None of this is the job. All of it is the job today. Here's what that list actually looks like, and why none of it should be sitting on your plate.

Most build-versus-buy debates assume you're choosing once, at the start, and living with it. Agentic engineering doesn't work that way. The decision shows up at every layer of the stack, and the teams getting it right aren't the ones who picked "build" or "buy" as a philosophy. They're the ones who know which layer is which.

Feasibility is a prioritization question that comes before strategy. The five-question check produces a "now, later, or fix blockers first", before anyone touches a target architecture. Strategy earns its place once feasibility returns "now." Feasibility comes before strategy. Before anyone designs a target architecture, builds a runbook, or commits to a multicloud operating model, the question is whether the migration is the right move now, and what would make it fail.

The instinct when adopting AI coding agents is to optimize the agent. Compare models, tune prompts, argue about which editor has the better completion, and treat the agent as the thing that determines how fast the team moves. Then the commits go up and the product does not. The team building Upsun Dispatch took a different route, and the result is worth copying. They did not find a better agent.

This assessment estimates how much exposure you carry. The output is a short read on which parts of your stack would resist a change you might need to make. The score is for an internal conversation that surfaces specific decisions.

Here's a scene playing out in engineering teams right now. An engineer spends the weekend running four or five coding agents in parallel. Monday morning, a teammate opens their laptop to 53 changed files with 2000+ diffs and a message that says, more or less, "should be good to merge." Nobody asked for this much output. Nobody has time to review it properly. The team doesn't feel faster. It feels ambushed.

Different teams ship on different clouds, each setup grows its own pipeline and runbook, and the fragmentation surfaces later as missed deadlines and extended audits. By then the operating-model debt has been compounding for months.

AI tools made individual developers faster. Teams still aren't shipping more product. That gap is the whole reason Upsun Dispatch exists. In this Product Highlights conversation, Kateryna Dvornichenko, a product manager at Upsun who has spent the past several months building Upsun Dispatch, explains why the tooling market got the unit wrong. Her take: "Making software is a team sport." We get into.

AI helped your engineers ship more code. It didn't help your team ship more product. So where did the bottleneck actually go? In this Product Highlights conversation, Patrick—a principal engineer at Upsun with twelve years building back-end APIs in Go—breaks down what changed once AI agents entered the workflow. His take: "The code isn't really a problem anymore. We can write that really fast. Everything else is still a bit behind the code." We get into.

Too often, we are told to highlight our weaknesses as a means for growth. From job interviews, to performance reviews, to our own self-reflection, we shine the light on what we do poorly. Building our careers isn't about doing everything well - instead, it's about doing what we already know we're good at to the best of our ability, and using the knowledge of our weakness to employ our strengths. Join Mary Thomas to learn why identifying and leaning into our strengths becomes our weakness Superpower.

From monolith to multi-app join us as we explore more in this Symfony demo: Once upon a time, great people created a great Symfony demo, to be used as a living code example and help us all learn: Bigfoot. Since then, the DevRel team at Platform.sh has forked this repo and created a really fun escape game to showcase Blackfire. And we thought it would be good to have a dedicated frontend for our game, instead of reusing the Bigfoot design.

It’s easy to assume that our users are experts when writing documentation. But technical writing without diagrams, code examples, videos, screenshots and more can ostracise a large chunk of users who are simply searching for help when using your product. When writing technical documentation, empathy allows us to imagine ourselves as the reader: a junior developer who just started on the job, a sales manager who needs more information for a client deck, a member of the customer success team helping a client on a video call.
