Why centron

Performance architecture for demanding big data workloads

A high-performance big data infrastructure consists of several layers: the hosting environment forms the technical basis for stable operation, compute resources deliver the processing power for analytics, streaming and HPC, and the storage architecture determines how efficiently large data volumes are processed, stored and served in parallel.

ccloud³ virtual machines

Worker Pool for light to moderate load, Power Pool for high CPU demands, High Availability for maximum resilience – start a data streaming VM today.

centron Kubernetes

Create a Kubernetes cluster in seconds and use the power of containerisation to scale streaming and analytics applications with ease.

S3 Object Storage

Store large volumes of data in an S3-compatible way – scalable data platforms, data lakes and flexible, API-based data access as it is common in big data and AI environments.

Volumes Block Storage

NVMe volumes for IO-intensive workloads with high parallelism: stable, predictable performance under load and additional SSD capacity when needed.

Use cases

Use cases for big data

The cloud infrastructure was designed specifically to map these use cases – with hosting as the technical foundation, compute resources for analysis, streaming and HPC processes, and a storage architecture that processes, stores and delivers large data volumes efficiently and in parallel.

Data analysis

Processing large volumes of structured and unstructured data – raw data from IoT systems, log files, transaction systems or sensors as the basis for analyses, machine learning models and real-time evaluations; the stack for it on data analytics.

Data streaming & real-time processing

Continuous processing of data streams with stable performance under high IO load – streaming frameworks such as Apache Kafka, Spark or Flink on ccloud³ VMs, Kubernetes clusters or dedicated servers.

AI and machine learning workloads

Training and inference with high data access and parallel processing – on GPU-optimised servers with an S3 data lake and NVMe volumes; details on LLM inference.

HPC and simulation environments

Compute-intensive workloads with predictable storage and throughput performance – HPC servers and block storage that delivers stable IOPS under parallel access.

Storage as a performance factor

Consistently high IOPS and stable latency

When analysing large data volumes, running HPC applications or processing data streams, consistently high IOPS and stable latency are what count – even powerful compute resources only realise their potential if the storage keeps up. Block storage delivers predictable performance under parallel access, and S3-compatible object storage carries scalable data platforms. And instead of operating the platform yourself, you can opt for a managed server model with technical responsibility for operations.

Frequently asked questions

What are typical requirements of big data workloads?

Large data volumes, parallel processing and high access rates. In addition to scalable computing power, stable storage performance, predictable latency and flexible expandability are decisive – otherwise analysis, AI or streaming processes become a bottleneck. In many scenarios, raw data is first collected unfiltered from IoT systems, log files, transaction systems or sensors and forms the basis for later analyses, machine learning models or real-time evaluations.

How do I process raw data or real-time data efficiently?

Raw data – whether system logs, telemetry data or user behaviour – can be processed via streaming frameworks such as Apache Kafka, Spark or Flink. Our Kubernetes clusters, VMs and GPU-optimised servers provide the necessary performance.

Can I rent servers from centron – including for Apache Kafka or Spark?

Yes: powerful dedicated servers, managed servers and VMs for applications such as Apache Kafka, Spark or Hadoop – flexible, secure hosting options for data streaming.

Which storage option is suitable for large data volumes?

For IO-intensive applications with high parallel access, block storage with predictable performance is recommended. For scalable data platforms, data lakes and API-based workflows, S3-compatible object storage is suitable. The optimal solution depends on the access pattern and load structure of your workload.

Why is storage performance so decisive for big data?

Analysing large data volumes, AI workloads or HPC applications generates high IO load. If the storage architecture cannot keep up, computing resources are slowed down. Constant IOPS and stable latency are therefore central factors for a high-performance platform.

Where is the data stored?

In highly secure data centres in Germany. This keeps data location, legal framework and data sovereignty clearly defined and traceable.

How does centron differ from classic cloud providers?

Standardised cloud models are primarily geared to broad self-service scenarios. centron focuses on performance-oriented infrastructure for demanding workloads – including dedicated resources, NVMe-based storage options and personal 24/7 support. Compare with IONOS.

Can the environment be operated in-house or fully managed?

Both. You manage your platform yourself or opt for a managed server with monitoring, performance optimisation and technical operational responsibility – especially with high IO load and growing data volumes, this relieves operations considerably.

Which streaming platforms can I run?

Apache Kafka, NATS, RabbitMQ, Redpanda or Apache Pulsar – self-hosted with root access on your VMs or in Kubernetes, without vendor lock-in.

How does a broker cluster stay fail-safe?

By distributing replicated brokers across several VMs in a VPC, with NVMe volumes for the logs and monitoring with alarms – a failed broker is compensated for by the others.

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

Yes. Event streams often carry personal data such as user IDs or IP addresses. At centron, brokers, logs and consumers remain in Germany, under a data processing agreement in accordance with Article 28 GDPR. The data centres are certified to ISO 27001 based on IT-Grundschutz; for ccloud³ / Managed Cloud there is an unqualified BSI C5:2020 Type 1 attestation. Details can be found in the Trust Center.
