Its actually B. I went with C initially but after further research Cloud Bursting isnt considered Scaling. Its temperory. So in this scenario they will need to scale by purchasing extra physical resources. VErtical makes more sense than Horizontal

Selected Answer: C
C. Cloud bursting Explanation: Private cloud resources can only meet 75% of the demand, meaning the company needs an additional 25% of capacity. Cloud bursting allows an application to run primarily in a private cloud while automatically "bursting" into a public cloud when demand exceeds private cloud capacity. This technique ensures that 100% of the application's resource needs are met while still prioritizing private cloud usage to minimize costs.

Folks, cloud bursting is the right response in this scenario. To accommodate 100% of the application's resource requirements, the cloud administrator can implement cloud bursting. This technique allows the application to primarily run on the private cloud 75% while leveraging public cloud resources to handle the additional 25% during peak demand. This approach optimizes resource utilization and provides flexibility without the need for permanent infrastructure upgrades.

B makes the most sense, vertical scaling involves increasing the capacity of your existing resources, in this case likely a server or VM which host the application. A would work but since this is an application, I would think B scales better. C would work but it is not the answer because it is stated in question that they want to utilize their private cloud to host the application. C, cloud bursting involves switching to a public cloud when extra resources are needed which contradicts them utilizing only their private cloud to host the application.

Let's be clear, vertical scaling is not the same as upgrading physical hardware. Vertical scaling is using different, more powerful hardware already existing within the cloud provider. But in this case it's a private cloud and it maxes out all resources with only 75% of the job done. C is the correct answer becasue you need to tap into the public cloud to finish the job. As defined by Vmware: "Cloud bursting is the practice of dynamically scaling public cloud resources to run workloads when on-premises data center resources are at their peak capacity. The overflow traffic “bursts” to a public cloud without causing an interruption in service." https://www.vmware.com/topics/glossary/content/cloud-bursting.html

Horizontal = provides more servers to support workload vertical = add more resources (capabilities) to existing VMs cloud bursting = relies on hybrid model; when on- premise cloud is over worked , it spills to public cloud autoscaling = adjusts to workload

Vertical makes the most sense. As pointed out in other posts the company wants to host in its private cloud. Cloud bursting is for temporary spikes in demand.

To accommodate the additional 25% of resource requirements for the new application, the cloud administrator can implement **Vertical Scaling.** - **Vertical Scaling (Upgrading the Existing Resources)**: In this approach, the administrator increases the capacity of the existing virtual machine (VM) or physical server by adding more CPU, RAM, storage, or other resources. This allows the application to use more resources from the same machine, making it suitable for scenarios where additional capacity is needed but doesn't require provisioning entirely new instances.

In contrast, the other options don't directly address this specific requirement: - **Horizontal Scaling (Adding More Instances)**: Horizontal scaling involves adding more virtual machines or instances to handle increased demand, not increasing the resources of existing instances. It's typically used for distributing the workload across multiple machines, which can be beneficial for redundancy and load balancing but may not address resource constraints on a single instance. - **Cloud Bursting (Using External Cloud Resources)**: Cloud bursting involves dynamically provisioning resources from an external cloud provider to handle peaks in demand. While this can provide additional capacity, it's usually used when private cloud resources are insufficient for the entire workload and you need to burst to a public cloud.

- **Autoscaling (Automatic Resource Adjustment)**: Autoscaling automatically adjusts the number of instances based on predefined policies to match demand. It's more about managing instance counts efficiently rather than changing the resource capacity of individual instances. In summary, to meet the requirement of accommodating the additional 25% of resource requirements using your private cloud, vertical scaling (upgrading the existing resources) is the most appropriate option.

They're not trying to temporarily meet demand which cloud bursting would provide, they're tying to "meet the application requirements". Vertically expanding their infrastructure another 25% will meet the requirements.

The want to utilize their private cloud, but resources are not good enough. "Cloud bursting" would mean to "only burst", but not use given resources. Only vertical scaling (B) of existing resources will help utilizing the given private cloud.

Option C, cloud bursting, is the most appropriate scaling technique for this scenario, as it allows a private cloud to seamlessly scale to a public cloud, enabling the application to access the resources it needs to function optimally. When the private cloud resources are insufficient, cloud bursting allows the application to utilize resources from a public cloud to meet the demand, and once the peak period is over, the private cloud can automatically reduce the resources it consumes.

There is nothing wrong with how the question is worded. The company has a "private cloud" and how can the "cloud admin" help? A, B and D all require more local hardware, C uses cloud resources and that is what it is asking.

Google... "What is cloud bursting? Cloud bursting is an application configuration that allows the private cloud to “burst” into the public cloud and access additional computing resources without service interruption." This seems to be a question about maintaining data/app in their own private cloud - but their infrastructure can't cope, so surely it's an in house vertical scaling issue.... Voting for Vertical.

I hope on the actual test the question is written better... or the question says pick all that apply... because A B and C all can accomplish the goal. The question doesnt even say which is the best way or cheapest way or fastest way... without any additional info, we are in limbo here.

if you look up the def of Cloud Bursting almost each of them is going to tell you, used extra or short term usage when the on prem is maxed out. Rarely will a new app being developed will you use a hybrid model. This is going to leave us with A and B, and still we'll need more information. Is price the guidance? buying a new CPU and Ram is cheaper... but what if there isnt an upgrade path there. If control over the app and its data is the primary guidance then horizontal is the way to go. Add a new server is a sure way to get what you need. This would probably be my test day pick if I get this one. Again I hope the actual test has some more wording to the question.

If they want to keep it in a private cloud wouldn't it be Vertical?

The answer is Cloud Bursting. It is a private cloud, if they did a vertical scale, they would just be buying new parts for their current equipment, they are trying to utilize the cloud.

They state the private clouds resources can only meet 75% of whats needed, they would need to upgrade hardware before they can vertically scale. They don't specify avoiding the cloud, just that they want to utilize it(not solely rely on cloud) so I think Cloud bursting here would make sense
