Cloud Burst
Cloud Burst
Cloud Burst is a configuration between Private Cloud and Public Cloud for dynamic scaling that burst temporary into Public Cloud when more computing resources are required. If the application is using a Private/Data Center and reaches 100% of its resource capacity, the overflow traffic gets redirected to Public Cloud so there is not any interruption of services. Once the traffic gets reduced data is moved back to the private cloud.
The advantage of this hybrid cloud model like cloud bursting is that an organization only pays for extra compute resources when they are needed.

Typically, this hybrid model is best for applications that tend to experience spikes and fluctuations in load.
Ex: Year-end sale sees an influx during shopping Season which can go beyond current capacity. Instead of purchasing any kind of new infrastructure bursting on the cloud is a better option.
How Cloud Bursting Deployed?
When workload capacity is near to threshold, the additional workload is moved to the public cloud for an application. The database and application initially have to move into Public Cloud, and it should synchronize with the private cloud. Here high-speed network connection is required to initiate and complete the operation in the public cloud. To carry out quick deployment application team should have periodically Database and Application backup on the public cloud also update incremental database backup so that smooth bursting can be completed in a limited time.
Cloud Burst Approach
The application team can choose one of the following options to Burst application on the Public cloud.

Cloud Burst Approach
The application team can choose one of the following options to Burst application on the Public cloud.
- Distributed Load balancing: It is an approach to use load balancing on each service to connect to the attached resources. This is an approach that can be extremely helpful for building micro-services or service-oriented architecture, where you have numerous resources that connect each other or require other services to complete some sort of functionality. This method needs an application to be deployed locally and in the public cloud and requires load balancing operations to share traffic.
- Automated Bursting: An organization set up a policy to define how and when bursting to handle. When Bursting set-up and reach the threshold an application hosted in a Private cloud can automatically burst over the public cloud.
- Manual Bursting: This technique will let you manually provision and de-provision cloud-based services and resources according to notifications sent from your load balancer.
