What Is Cloud Bursting, and Why Is It Important? Hybrid cloud

Summary

In this video, the concept of cloud bursting within hybrid cloud computing is explained. Cloud bursting occurs when a service, hosted on a private cloud, experiences unexpected traffic spikes that exceed its capacity. In such cases, the service ‘bursts’ into the public cloud to manage the increased load, offering scalability and flexibility. The key advantage is that you only pay for the time the public cloud is used during the spike, making it a cost-effective solution. Cloud bursting is a prime example of leveraging both private and public cloud infrastructures to meet fluctuating demands.

Takeaways

• 😀 Cloud bursting is a crucial concept for cloud-related roles, such as cloud analysts or AWS analysts.
• 😀 Hybrid cloud computing refers to the integration of both public and private cloud environments.
• 😀 Cloud bursting occurs when a private cloud cannot handle increased traffic, leading to the use of public cloud resources.
• 😀 An example of cloud bursting is when a web service sees a traffic spike, and the private cloud's servers can't meet the demand.
• 😀 In cloud bursting, the private cloud handles regular load, while the public cloud is used to manage traffic spikes.
• 😀 When the load decreases, the system returns to using the private cloud, optimizing costs.
• 😀 The public cloud is only utilized during the spike, and users only pay for the duration of the increased load.
• 😀 Cloud bursting is a great example of how hybrid cloud environments effectively combine the strengths of both private and public clouds.
• 😀 This concept highlights the practical use of both private and public clouds based on demand fluctuations.
• 😀 Understanding cloud bursting is key to understanding how hybrid cloud computing addresses scalability and cost efficiency.
• 😀 Cloud bursting provides a flexible, on-demand solution for handling unpredictable traffic and ensuring optimal performance.

Q & A

What is cloud bursting?

Cloud bursting is a hybrid cloud concept where an application hosted on a private cloud automatically shifts to a public cloud when there is a spike in traffic or demand. Once the traffic decreases, it returns to the private cloud.

What is hybrid cloud computing?

Hybrid cloud computing refers to a combination of public and private cloud environments working together. This allows businesses to benefit from the flexibility of both cloud types.

When would cloud bursting be used?

Cloud bursting is used when there is an unexpected surge in traffic or demand on a private cloud infrastructure, which the private cloud alone cannot handle. The application 'bursts' into the public cloud temporarily to accommodate the increased load.

What is the difference between private and public clouds in the context of cloud bursting?

In cloud bursting, the private cloud is used to handle regular, normal traffic. However, when demand spikes beyond the capacity of the private cloud, the public cloud is used to handle the excess traffic. After the load decreases, the system returns to the private cloud.

How does cloud bursting help in handling traffic spikes?

Cloud bursting allows for seamless scaling of resources by temporarily utilizing public cloud resources during periods of high demand, ensuring that the application remains accessible without needing to permanently increase the capacity of the private cloud.

What are the costs associated with cloud bursting?

The costs of cloud bursting are based on the duration of the spike when the system is using the public cloud. You only pay for the time the application is running in the public cloud, not for the entire duration the service is active.

Why is cloud bursting considered an important concept in hybrid cloud environments?

Cloud bursting is important because it demonstrates the ability to dynamically scale resources between private and public clouds, providing a flexible and cost-effective solution for handling unpredictable traffic without over-provisioning resources.

Can you provide an example where cloud bursting would be useful?

A good example is a web hosting service. If a web hosting application starts with 100 users but experiences a sudden spike to 10,000 users, cloud bursting allows the application to scale up using public cloud resources until the traffic returns to normal levels.

What happens when the traffic load decreases after using the public cloud in cloud bursting?

When the traffic load decreases, the application will shift back from the public cloud to the private cloud, optimizing costs and resources.

How does cloud bursting benefit businesses from a practical standpoint?

Cloud bursting provides businesses with the ability to handle unpredictable traffic surges without needing to constantly upgrade their private cloud infrastructure. This offers both cost savings and efficient resource usage, while maintaining performance during high-demand periods.
