Infrastructure & Data – Back-ends for apps of all sizes

Web and mobile apps: robust back-ends

APIs, databases, push notifications and uploads for your app – built on infrastructure that will stand the test of the launch and grow in line with App Store downloads.

Why centron

Everything an app backend needs

Behind every good app is a backend that can cope with surges in traffic without users even noticing.

APIs that scale

REST and GraphQL backends run in Kubernetes with AutoScaler – including feature launches and release waves.

Data stored securely

PostgreSQL/MongoDB on NVMe volumes for user data, S3 for uploads and media – every type of data in the right place.

Keeping an eye on latency

Advanced Monitoring measures API response times from the outside – you can see what your users are experiencing.

The GDPR for app stores

Deutsche Datenhaltung addresses the data protection queries of users, auditors and enterprise customers all at once.

From launch to growth

A backend roadmap for your app

The MVP runs on a VM with an API and a database; following the launch, Kubernetes and the load balancer handle scaling, whilst staging environments are created via snapshots for each release. S3 delivers uploads and assets without incurring any egress costs.

Infrastructure & Data FAQ

Frequently Asked Questions

Can the backend cope with a feature launch involving a push notification to all users?

That’s what it’s designed for: the AutoScaler adds API replicas as soon as the push wave arrives, with databases running on fast NVMe volumes – and once the wave has passed, everything scales back down. This can be tested in advance using a load test on a staging clone.

How much does it cost to get started?

The starting prices are deliberately low: Kubernetes from €29.99 per month, volumes from €0.05 per GB per month and S3 Object Storage from €5.00 per month. New accounts receive a €200 starting credit valid for 60 days – you can calculate the cost of your specific configuration transparently using the price calculator.

Can this be implemented in a way that complies with the GDPR?

Yes. With apps, user accounts, device IDs and analytics data are personal data – the latter in particular often ends up with third-party providers without users realising. With centron, your backend, including user data, remains in Germany, with a data processing agreement in accordance with Article 28 of the GDPR. Operations take place in certified to ISO 27001 on the basis of IT-Grundschutz data centres; for ccloud³ / Managed Cloud, we hold an unrestricted BSI C5:2020 Type 1 certificate. You can find details in the Trust Centre.
