Serverless sounds like less effort – no server, no worries. In reality, it's more like: less infrastructure, more architecture thinking.
I've been working intensively with Zoho Catalyst over the last few weeks – a platform that promises to combine the best of serverless and classic app development.
What "Serverless" really means
Serverless doesn't mean no servers exist. It means you don't have to worry about them. Everything runs in managed services – functions, auth, datastore, file storage. Sounds dreamy, right?
The advantages
What I find particularly strong:
- Fast scalability – your application grows automatically with traffic and requirements.
- Fully equipped ecosystem – auth, storage, cron jobs, caching and more are directly available.
- Fast iteration & deployment – you push new features directly live without server configuration.
- Large apps are also possible – Catalyst is suitable not only for prototypes but for complex, multi-layered applications with API layers, data processing and frontend integration.
- Focus on business logic – you waste less time on infrastructure and can focus more on features, processes and UX.
- Integrated security – auth and permissions are directly available, which facilitates compliance.
- Event-driven architecture – functions react automatically to events (e.g. file uploads, data changes), making complex workflows easy to orchestrate.
The practice: Freedom with limits
I love how quickly you can get started. But:
- Monitoring is more complex if you don't have your own logging setup.
- Local development can be tricky, especially because of authentication. With Catalyst, you often have to build workarounds for tests to correctly authenticate local requests.
- Dependency on the platform requires conscious architecture design to avoid lock-in. (In my current project, I use a Vue/Nuxt frontend where you could switch to another serverless platform at any time.)
My conclusion
Serverless saves time – but only if you consciously plan architecture. Functions quickly grow out of hand if they don't have a clear structure.
My tip: Build a clean routing concept early and keep functions small and focused.
