Vendor Lock-in – When Architecture Becomes Dependency
Vendor lock-in refers to the technically, economically, or legally restricted ability to switch an IT service provider or platform vendor without significant effort.
In other words: In theory, you could leave – but practically, it’s no longer an option.
This dependency doesn’t happen overnight. It grows gradually.
A Managed Service here, an auth system there, some monitoring, a bit of IAM. Everything interlocks, everything works seamlessly. Until you eventually realize: Your entire stack is inextricably linked to just one provider.
And now? Every switch means time, money, re-architecture.
So you stay. And that’s exactly what the business model is based on.
Why Lock-in is so Dangerous
The problem with lock-in isn’t that a service is bad. Many platform services are technically strong.
The problem is: You relinquish control – often without realizing it. And you don’t get it back when it matters.
- Pricing changes? You swallow it.
- Regional compliance requirements change? You wait for the next service update.
- A critical bug needs to be patched in a core system? You’re reliant on your provider’s pipeline.
What you lose is not just flexibility. You lose strategic agility – and that in an environment that is constantly changing.
Controlled Architecture vs. Vendor Lock-in
| Feature | Controlled Architecture | Vendor Lock-in |
|---|---|---|
| System change possible? | With manageable effort | Only with high investment or downtime |
| Dependency on APIs | Standardized, interchangeable | Proprietary, non-portable |
| Platform binding | Loose coupling | Deeply integrated into operational logic |
| Control over data | Own backup & recovery procedures | Restricted by platform specifications |
| Adaptation to new requirements | Quickly and internally manageable | Only via the provider’s feature roadmap |
Technically, the difference is often not visible – until you have to migrate. Or want to switch providers. Or simply aren’t willing to react to the provider’s next policy change without it affecting your entire system.
Lock-in is Not a Technical Necessity
The truth is: Most lock-ins are self-inflicted.
They arise from convenience, from tooling, from unreflective trust in “Managed” and “as-a-Service” promises.
But: Every proprietary service that deeply embeds itself in architecture, monitoring, logging, authentication, or data management is a strategic anchor. The more you have, the heavier you become – at the most inopportune moment.
Vendor lock-in is not a bug. It’s a feature. And one that remains inconspicuous for a very long time – until you lose it: Control.
Conclusion:
You don’t have to operate everything yourself. But you should always be able to operate everything yourself.
If you don’t have a clear answer to that, you don’t have a system. You have a subscription.
