At a Glance: Cloud Bursting with STACKIT

  • Key Topic: Cloud bursting is a hybrid cloud model that protects IT systems from overload. During sudden traffic spikes, additional resources are automatically provisioned from the public cloud, while regular operations remain in the private cloud.
  • How it works: Intelligent orchestration tools monitor thresholds (e.g., CPU or network utilization). When needed, defined workloads are dynamically offloaded. As soon as the load decreases, the resources are automatically scaled back.
  • The key benefits of STACKIT:
    • Data sovereignty & compliance: Sensitive data remains in the secure private cloud. All additional public cloud resources are 100% GDPR-compliant and run in German and Austrian data centers.
    • Cost Control: Thanks to the pay-per-use model and automatic scaling back, you pay only for the capacity you actually use during peak loads. There is no need for expensive excess capacity.
    • Reliability: Guaranteed performance even during periods of extreme traffic (e.g., in e-commerce on Black Friday, during government deadlines, or for computationally intensive research projects).
  • Conclusion: Cloud bursting with STACKIT is not merely an emergency solution, but a strategic, automated architecture that combines maximum scalability with strict European security standards.

Cloud Bursting with STACKIT: How Dynamic Scaling Works in Detail

Cloud bursting is a proactive, intelligent extension of your infrastructure—in other words, far more than just an emergency solution. Through the combination of automated resource management and modern hybrid cloud architecture, the system responds specifically and autonomously to changing demands.

Intelligent Load Balancing: Managing Workload in Real Time

During normal operation, your application runs securely and efficiently in the private cloud or on your existing on-premises infrastructure. When load spikes occur—for example, due to growing user numbers, special promotions, or new digital services—STACKIT’s integrated orchestration tools continuously analyze key system metrics such as CPU, memory, and network utilization. If predefined thresholds are exceeded, the system automatically activates the expansion of additional capacity from the public cloud—precisely tailored to actual demand.

Precise Workload Migration: Optimally Balancing Utilization and Protection

Not all tasks are equally suitable for offloading: With STACKIT, you can determine at a granular level which workloads are temporarily moved to the public cloud—such as computationally intensive analyses, web servers, application instances, or specialized data services. Sensitive data and business-critical applications remain protected in your private cloud at all times. Through centralized management platforms and policy-based settings, you maintain control over the processing, location, and security level of your resources at all times.

Efficiency Through Automation and Open Standards

STACKIT consistently relies on automation for cloud bursting—from detection to provisioning and the subsequent rollback of resources. Standardized interfaces such as Kubernetes, Infrastructure-as-Code, or API-based tools enable seamless integration with existing clouds and IT landscapes. Scaling is not done on a flat-rate basis, but precisely as needed: capacities can be provisioned incrementally and automatically reduced once the peak load has passed. This ensures your applications always run at peak performance without you having to pay too much or intervene manually.

Maximum transparency and compliance—traceable at all times

Every change to your hybrid infrastructure is comprehensively recorded. Through central dashboards and monitoring tools, you can track system status, utilization, data flows, and billing in real time. Reports and compliance features make it easy to reliably meet regulatory requirements and internal audit processes. This ensures that your hybrid operations are not only technically efficient but also legally compliant and transparent to all stakeholders.
