[All CV0-003 Questions]

A company is utilizing a private cloud solution that is hosted within its datacenter. The company wants to launch a new business application, which requires the resources below:

The current private cloud has 30 vCPUs and 512GB RAM available. The company is looking for a quick solution to launch this application, with expected maximum sessions to be close to 24,000 at launch and an average of approximately 5,000 sessions. Which of the following solutions would help to company accommodate the new workload in the SHORTEST amount of time and with the maximum financial benefits?

  • A. Configure auto-scaling within the private cloud.
  • B. Set up cloud bursting for the additional resources.
  • C. Migrate all workloads to a public cloud provider.
  • D. Add more capacity to the private cloud.

Why not auto-scaling A?

According to the scenario there aren't enough internal resources.

But the chart says it'd take less than "30 vcpu's" and "512GB" of memory. I think it's moreso that while auto-scaling WOULD work, autoscaling is more appropriate for when the average load increases, not when there's a short period of a boost in activity. Cloud bursting is just "more relevant".

if I'm understanding this correctly, then the current PC doesn't have enough resources for 24,000 sessions, but could handle the average 5000. It is a little unclear because you arnt given the exact numbers to work with but we know for sure we don't have enough for 25,000 sessions. So while auto scaling could work on a potentially lower load (say something like 20,000 maybe), I don't think it would work here. So really the only other feasible option is cloud bursting.

It's B. At 25,000 sessions it requires 8 nodes and 8 vCPUs per node. The Maximum number of vCPUs they have is 30. (8 Nodes x 8 vCPUS = 64 vCPUs.) Without even needing to look at the rest of the question we can see they don't have the requirements to support 25,000 sessions, though they state the max sessions to be 24,000 for them. That being said Cloud bursting would allow them to pay for the extra resources that they need ONLY when they need it. It's not auto-scaling because were talking about an On-Prem stiuation that would need to get it's additional resources from the clous and autoscaling typically refers to a cloud resource scaling up or out from within the cloud or at least isn't as defined as Cloud-Bursting is. Adding more capacity is certainly not cost effective considering they don't always have the maximum workload of 24,000 sessions. B is your best bet.

Given the requirement for the shortest time to accommodate the new workload and maximum financial benefits, option B: Set up cloud bursting for additional resources appears to be the most suitable choice. Cloud bursting leverages the existing private cloud infrastructure while providing additional resources from the public cloud as needed, offering scalability, quick deployment, and potential cost savings.

Cloud Bursting Another approach to meeting service requirements is cloud bursting. Cloud bursting relies on a hybrid cloud model. If the private, on-premises cloud service reaches saturation, the workload can spill over into the public cloud. Of course, using public cloud resources incurs costs, but such costs are better than poor or no service due to a lack of resources.

Cloud Bursting can be used for both compute and storage. This question is about compute capability. "Compute Bursting" unleashes the high-performance compute capabilities of the cloud for processing locally created datasets. (reference: https://www.ctera.com/it-initiatives/cloud-bursting/)

*cloud bursting* Concept of running an application on the organization’s internal computing resources or private cloud and “bursting” that application into a public cloud on demand when the organization runs out of resources on its internal private cloud.

The quickest method would be to configure auto-scaling within the private cloud. There is no mention of the company having any public cloud solutions which is what cloud bursting consists of.

The correct answer is "B." Cloud Bursting will provide the quickest deployment for the private cloud by overflowing into the public cloud. This will save time and money in order to provide continued service without interruption. https://azure.microsoft.com/en-us/overview/what-is-cloud-bursting/

After some re-evaluations with my peers, I would like to change my answer to "D." For the following reasons: For maximum financial benefit, the load has to be able to handle a maximum expected capacity without dropping sessions. The different scaling unfortunately makes this portion confusing... however, it is enough for a 5,000 maximum (with the expectation of a 5,000 average), there will be some that wouldn't be able to be accommodated for. For more clarity: If 5,000 concurrent sessions are needed, the 4 nodes are required. Each node requires 6 vCPUs at the 5,000 mark. So if you're math is 4 nodes x 6 vCPU per node, you will equal out to 24 vCPUs. By doing the same thing for RAM, each node requires 64GB of RAM at the 5,000 mark. Then at that point, your math would be 4 nodes x 64GB of RAM, you will equal out to 256GB of RAM at that level. That is for the "AVERAGE" consumption. So for the initial consumption, you wouldn't have enough resources.

That option is by no means the cheapest or the fastest however, since it would require purchasing and standing up hardware in your own data center.
