Handling demand for computing resources in a cloud computing: Vertical Cloud Bursting VS Horizonal Cloud Bursting

   Vertical cloud bursting and horizontal cloud bursting are two different approaches to handling sudden spikes in demand for computing resources in a cloud computing environment. While both approaches involve scaling up an application's resources to meet increased demand, there are significant differences between the two.

Vertical Cloud Bursting:

    Vertical cloud bursting, also known as scaling up, involves adding more resources to an existing virtual machine or application instance. This can include increasing CPU or RAM, adding storage, or upgrading the network connection. Vertical cloud bursting is useful when an application requires additional processing power or memory to handle increased demand.

    The advantage of vertical cloud bursting is that it is relatively simple to implement and can be done without the need to spin up additional virtual machines or containers. However, there are limitations to vertical cloud bursting, as there is a limit to the amount of resources that can be added to an existing instance. Additionally, vertical cloud bursting may not be able to handle large spikes in demand, as the existing virtual machine may not have enough capacity to handle the increased load.

Horizontal Cloud Bursting:

    Horizontal cloud bursting, also known as scaling out, involves adding more computing instances to an application or infrastructure to handle increased demand. This can include spinning up additional virtual machines, containers, or servers. Horizontal cloud bursting is useful when an application requires additional processing capacity to handle increased demand.

    The advantage of horizontal cloud bursting is that it can handle sudden spikes in demand more effectively than vertical cloud bursting, as additional resources can be added quickly and easily. Additionally, horizontal cloud bursting can be more cost-effective than vertical cloud bursting, as resources can be scaled out as needed and then scaled back down when demand decreases.

    However, horizontal cloud bursting can be more complex to implement and manage than vertical cloud bursting, as it requires coordination between multiple virtual machines or containers. Additionally, horizontal cloud bursting can result in additional costs, as additional virtual machines or containers may need to be spun up to handle increased demand.

    In summary, vertical cloud bursting involves adding more resources to an existing virtual machine or application instance, while horizontal cloud bursting involves adding more computing instances to an application or infrastructure. Vertical cloud bursting is simpler to implement but has limitations in terms of scalability, while horizontal cloud bursting is more complex to implement but can handle sudden spikes in demand more effectively.
