You are currently managing workloads running on Windows Server for which your company owns the licenses. Your workloads are only needed during working hours, which allows you to shut down the instances during the weekend. Your Windows Server licenses are up for renewal in a month, and you want to optimize your license cost.
What should you do?
Migrating the workloads to Compute Engine with a pay-as-you-go (PAYG) model is the best option to optimize your license costs. Given that the workloads are only needed during working hours and can be shut down on weekends, the PAYG model allows you to pay for licenses only when the instances are running. This way, you avoid the expense of renewing licenses for an extended period and only incur costs based on actual usage, making it more cost-efficient.
D for me, it says "optimize your license cost" and that license will expire in one month, so I would go with a Pay-As-You-Go model
D is correct
C is correct. Migrating your workloads to Compute Engine with a BYOL model would allow you to utilize your existing Windows Server licenses while also benefiting from the flexibility and potentially lower costs associated with cloud computing. This way, you can optimize your license costs by using your existing licenses efficiently and take advantage of Compute Engine's pricing structure. Additionally, you can explore further cost-saving measures such as scheduling instances to shut down during weekends when they're not needed.
As the license is already expiring so PAYG model will be more efficient here.
You are currently managing workloads running on Windows Server for which your company owns the licenses. Your workloads are only needed during working hours, which allows you to shut down the instances during the weekend. Your Windows Server licenses are up for renewal in a month, and you want to optimize your license cost. D is the correct answer. The question clearly states that we are running Windows Server with our own licenses (BYOL). These instances are already on GCP, we want to optimize licensing cost. Keeping BYOL (C) won't affect our infrastructure, D will. With PAYG, we are paying an extra fee while the VM is running, meaning if you turn off the Vm, you are not paying the license. This will optimize our costs, as we are not expending a big portion of money to pay the license, but only a fraction for usage.
In the given scenario, the goal is to optimize license costs for workloads running on Windows Server, which are only needed during working hours. Considering this, the most cost-effective option would be to choose a pay-as-you-go (PAYG) model in Google Cloud's Compute Engine.
Pay as you go
By distributing the virtual machines across different zones within the same region, your organization can ensure redundancy in case of any zone-specific failures or disruptions. This setup provides high availability and fault tolerance. Additionally, locating the virtual machines within the same region allows for fast communication between them, as the network latency within a region is typically lower compared to communication across regions. This ensures that the parts of the application can communicate with each other in less than 10 milliseconds, meeting your organization's requirement for fast communication. Choosing multiple regions (Option C) or multiple zones per region (Option D) may provide additional redundancy but could potentially increase network latency, which may not meet the requirement for extremely fast communication.
D is the correct answer. But GPT say answer C ?
Option D for me
It's D, because with D you do not need to bring your licenses (Correct me if I'm wrong), and the scenario says there is no need to have it up and running during the weekends.
Answer is C
C, BYOL model is correct: The cons of D PAYG are: Higher cost: The PAYG model typically includes a premium on top of the per-second resource usage cost to cover the included license fees. This could be more expensive than BYOL, where you leverage your existing licenses. Recurring cost: You continuously pay for the license fees as part of the PAYG model, even when your workloads are not running. This contrasts with BYOL, where you only pay for the new license once, and only pay for resource usage during active hours.
D is the correct answer the license will expire in 1 month.
See the problem with D is that, any VM cost does not cover the cost of Licensing. If you want to have a VM running RHEL, then you need to get RHEL licenses on your own. Google can help you with that, but License of S/W usage is extra, above and beyond N/W, Disk, Compute and Memory.
I think it's D, because BYOL is only available with Bring Your Own Image for Windows Server (https://cloud.google.com/blog/products/compute/compute-engine-licensing-explained), which is only available to run on dedicated hardware, which I think would end resulting much more expensive. Pay-As-You-Go allows you to optimize your "License" costs, because you only pay for the license as long as the instance is in use. With BYOL you're not optimizing anything as you still have to pay the full license for each instance.
C for me, because we are talking about stable and predictable workloads, PAYG is best for variable workloads when you need scale up or down your resources.
