Cloud Bursting
Commonly used in Cloud Computing, Networking
Cloud bursting is a configuration that integrates a private cloud with a public cloud to handle spikes in IT demand. It allows an organization to seamlessly extend its computing resources by leveraging external cloud services when internal capacity is insufficient, ensuring continuous service availability.
How It Works
In a cloud bursting setup, the private cloud operates as the primary environment for running applications and managing workloads. When the demand exceeds the private cloud's capacity—such as during peak usage periods—the system automatically redirects excess workloads to the public cloud. This process involves configuring workload orchestration and resource management tools that monitor resource utilisation in real time. These tools determine when to "burst" into the public cloud, dynamically provisioning additional resources only when needed. Once the demand drops back to normal levels, workloads are shifted back to the private cloud, and the public cloud resources are released, making the process cost-effective and flexible.
Common Use Cases
- Handling seasonal traffic spikes for e-commerce websites during holiday sales.
- Managing unpredictable workloads in large-scale data analysis or research projects.
- Supporting development and testing environments that require extra computing power temporarily.
- Scaling applications during major product launches or marketing campaigns.
- Providing disaster recovery by temporarily offloading workloads to the public cloud during outages or system failures.
Why It Matters
For IT professionals and organisations, cloud bursting offers a strategic way to balance cost and performance by dynamically adjusting resources without over-investing in private infrastructure. It enables businesses to respond quickly to changing demands, optimise resource utilisation, and improve service reliability. Certification candidates working towards cloud or infrastructure certifications should understand cloud bursting as part of hybrid cloud strategies, as it demonstrates the ability to design scalable, flexible, and resilient cloud environments. In a competitive IT landscape, mastering cloud bursting concepts can lead to better resource management and more efficient cloud architecture design.
Frequently Asked Questions.
What is cloud bursting in cloud computing?
Cloud bursting is a hybrid cloud configuration where an organization uses a private cloud for regular workloads and automatically shifts excess demand to a public cloud during peak times. This ensures scalability, cost efficiency, and continuous service.
How does cloud bursting work in practice?
In cloud bursting, workload management tools monitor resource usage in real time. When demand exceeds private cloud capacity, workloads are dynamically transferred to the public cloud. Once demand drops, workloads return to the private cloud, optimizing resources.
What are common use cases for cloud bursting?
Cloud bursting is used to handle seasonal traffic spikes, large data analysis workloads, testing environments, application scaling during launches, and disaster recovery scenarios. It provides flexible, on-demand resource expansion.
