[Guide] Stop blocking your deployments with long-running crons ⏳

Flora Brandão — Thu, 07 May 2026 14:00:00 +0000

Long-running crons are likely stealing resources from your app container and creating unnecessary support tickets. If your crons are blocking your deployments, you are dealing with a major engineering grind that slows down your entire team.

The fix is often simpler than you think. You should move those heavy tasks to workers instead. Here is why it matters for your workflow:

Workers handle deployments better than framework schedulers
Moving to workers prevents resource theft from your main app
Using workers stops the cycle of deployment blocks and support tickets

It is important to know when a cron is fine and when it is time to switch to a modern alternative. Making this change keeps your environment stable and your deployments moving.

Beyond the vibe coder ceiling 🛠️

Flora Brandão — Mon, 04 May 2026 14:00:00 +0000

Building a project with AI is fast and easy but keeping it running is the real engineering grind*. If anyone can generate code with a prompt, you might wonder if traditional software companies still have a future.*

The reality is more nuanced than the current hype suggests. Here is what you need to know about the current shift:

Creating software is not the same as keeping it running for the long term.
Many developers are hitting a ceiling where AI generates code but cannot manage the complexity of a live system.
Simple SaaS products and indie hackers are facing a race to the bottom as barriers to entry drop.
Established software companies use their enterprise moats and AI tools to maintain their lead.
The 1/3 rule still dictates how value is created and sustained in production environments.

Understanding these trends helps you focus on building software that actually lasts. It is about moving past the initial code generation and into the practical reality of maintaining a business.

[Guide] Stop 502 errors with queues ⚡

Flora Brandão — Mon, 04 May 2026 10:00:00 +0000

Is your website throwing 502 errors whenever an external API starts lagging? It is a common engineering grind where slow dependencies choke your server and kill your response times.

The fix is not adding more resources. It is about changing how you handle work.

Stop making users wait for external processes to finish.
Offload heavy tasks to background jobs and queues.
Distinguish between workers and crons to optimize your flow.
Keep your main thread fast and responsive.

Moving work to a queue ensures your site stays stable even when external services are slow. It is a simple pattern that keeps your workflow lean and your users happy.

Check out the full technical breakdown:

Setting up Drupal Canvas with AI on Upsun, a step-by-step guide 🔥

Celeste van der Watt — Tue, 17 Feb 2026 11:35:58 +0000

Here’s the candid, no-hype version of what really happens when you ask AI to spin up Drupal Canvas on a live environment.

Taras Kruts walks through a Cursor-assisted build that hits four classic snags: the AI picks the wrong Composer package, over-generates boilerplate, confuses Platform.sh vs Upsun configs, and tries to use a non-existent install profile.

He then shows the simple fixes, plus a reliable deploy hook that installs Drupal and enables Canvas automatically so every preview environment comes up clean on Upsun. The punchline: AI drafted the scaffolding fast, but human review and a few precise edits made it production-credible in about 1 hour 25 minutes.

Why you should check out the full demo:

You’ll avoid the same AI setup traps and copy known-good commands instead of guessing.
You’ll see how to use Upsun’s Git-driven YAML and per-branch preview environments to demo Canvas live for stakeholders without babysitting infra.
If you’re juggling incidents and context switching, this is the kind of repeatable workflow that gives you time back for actual feature work. ves
Cuts the “AI said it would work” thrash by naming exact failure modes and fixes.
Replaces manual setup with an automateinstalls Drupal and enables Canvas on every environment.
Shows a practical path to ship demos faster on an opinionated platform designed for speed, standardization, and reliability.

Speed up delivery across branches, and reduce infra toil on your next Drupal launch.

Create secure tunnels between Upsun projects with Chisel

Celeste van der Watt — Wed, 27 Aug 2025 15:40:09 +0000

By default, Upsun projects are isolated for security. Applications and services inside one project cannot directly talk to another. But what if you need to connect them? Think database replication, multi service integration, or disaster recovery setups.

In our latest post, we show how to use Chisel, a lightweight tunneling tool, to securely connect multiple Upsun projects. It is fast, encrypted, and designed for scenarios where cross project communication is essential.

With Chisel, you get:

Secure tunnels for encrypted traffic between projects
Simple configuration in .upsun/config.yaml
Support for MariaDB replication and beyond
Resilient connections with auto reconnect and error recovery

Whether you are syncing databases across regions or wiring services together, Chisel makes it possible while keeping isolation as the default.

We solved container networking at massive scale (and you can learn how) 🚀

Celeste van der Watt — Thu, 07 Aug 2025 07:34:11 +0000

Ever wondered how we manage networking for tens of thousands of containers without breaking a sweat? 🤔

Traditional networking approaches fall apart when you're dealing with high-density containers that are constantly being created, destroyed, and moved around. Centralized systems become bottlenecks, and suddenly your infrastructure is more fragile than a house of cards.

So we built something different: a stateless mesh networking system that embeds routing information directly into IP addresses. No databases, no control planes, no drama. ✨

Here's what we achieved:

8,192 containers per VM (yes, you read that right!)
Zero network bottlenecks through direct VM-to-VM communication
Instant service discovery - new containers become routable immediately
Predictable performance that scales with your infrastructure

The secret sauce? We borrowed inspiration from IPv6's IPv4-mapped addresses and embedded VM information right into the container IP addresses. When a packet needs routing, our custom ARP daemon extracts the target VM's IP from the destination address and creates direct point-to-point connections.

Our latest deep-dive article walks you through the entire technical implementation, from the initial challenges to the creative solutions we found in "reserved for future use" IPv4 space.

This is why your Upsun preview environments spin up in minutes, not hours. The networking just works - invisibly and instantly. 💪
