App-Entwicklung: App Cloud & Database

App Cloud &Database

Behind every scalable app is a well-designed cloud and database architecture. Whether relational databases, NoSQL, managed services, or serverless infrastructure – the right architecture determines whether your app stays stable under load, costs remain manageable, and you can sleep at night. We design and operate cloud infrastructure that grows with your app.

Challenges you'll recognise

  • Your app becomes unstable under increased traffic and you cannot tell whether the backend or the database is the bottleneck.
  • You have no automated backups and do not know if you could recover your app data in an emergency.
  • Infrastructure costs are scaling faster than your user numbers – you are losing money without knowing where.

Database Selection

PostgreSQL, MySQL, MongoDB, Firebase, or DynamoDB – the choice of database influences performance, cost, and maintenance overhead for years. We analyse your data patterns, query requirements, and growth expectations and recommend the database that suits the app long-term – not whatever is currently trendy.

Cloud Infrastructure

We deploy app backends on AWS, Google Cloud, or Azure – with infrastructure as code, automated backups, monitoring, and defined scaling rules. Managed services reduce operational overhead while the infrastructure is provisioned for peak load.

Data Security

App data is often sensitive. We implement encryption at rest and in transit, role-based access controls, and regular backup tests that confirm a restore actually works – not just in theory.

Scalability

We build infrastructure that grows with your app: horizontal scaling for compute, read replicas for database load, CDN for static assets, and connection pooling for efficient database usage. Growth should mean success, not an infrastructure crisis.

Good to know

  • Infrastructure as Code

    We manage cloud infrastructure as code – reproducible, versioned, and auditable. New environments are created in minutes from the same configuration, without manual setup errors.

  • Monitoring and Alerting

    We set up monitoring for all critical metrics: response times, error rates, database load, and memory usage. Alerts fire before users notice problems.

  • Tested Backups

    Automated backups are the prerequisite. Regularly tested restores are the guarantee. Both together are the only honest claim about data safety.

Frequently asked questions

Which cloud provider is recommended for apps?
AWS, GCP, and Azure are all production-ready. The choice depends on requirements, team expertise, and any existing contracts. We have experience with all three and recommend based on your situation.
When is SQL better than NoSQL for an app?
When your data is structured, relational queries matter, and consistency is a priority – then SQL. NoSQL suits flexible schema requirements, high write loads, and denormalised data access patterns. For many apps a combination makes sense.
How is it ensured that backups work when they are actually needed?
Through regular, documented restore tests. A backup that has never been tested is not a backup. We set up automated backups and run restore tests at defined intervals.
