Professional Cloud ArchitectAnalyze and optimize technical and business processesMedium
A global online gaming company is experiencing significant fluctuations in user traffic, with peak loads during evenings and weekends. Their current infrastructure on Google Cloud uses a fixed number of Compute Engine instances, leading to over-provisioning during off-peak hours and performance degradation during peak times. The company wants to optimize costs while ensuring consistent performance. Which Google Cloud feature would be most effective for this scenario?
- AManaged Instance Groups (MIGs) with autoscaling.
- BSole-tenant nodes for dedicated game server hosting.
- CPreemptible VMs for stateless game servers.
- DCommitted Use Discounts (CUDs) for Compute Engine.
Show answer & explanationAnswer & explanation
Correct answer: A. Managed Instance Groups (MIGs) with autoscaling.
Managed Instance Groups (MIGs) with autoscaling dynamically adjust the number of instances based on demand, which is ideal for fluctuating workloads. This ensures consistent performance during peak times and reduces costs by scaling down during off-peak hours, directly addressing the company's requirements.
Why the other options are wrong
- B. Sole-tenant nodes provide dedicated hardware for specific compliance or licensing needs, but they are expensive and do not offer dynamic scaling for cost optimization with fluctuating workloads.
- C. Preemptible VMs are cost-effective for fault-tolerant, stateless workloads, but they can be terminated at any time, which might not be suitable for all game server components, and don't inherently handle scaling up for peaks reliably.
- D. CUDs reduce costs for predictable, consistent workloads, but don't address fluctuating demand or performance degradation during peaks.
Managed Instance Groups (MIGs)
A collection of virtual machine instances that you can manage as a single entity, offering features like autoscaling, autohealing, and rolling updates.
- Autoscaling: Automatically adds or removes VMs based on load.
- Autohealing: Recreates unhealthy VMs.
- Rolling updates: Simplifies application deployment and updates.
- Regional and zonal deployment options for high availability.
Memory trick: MIGs make your instances morph to match demand's might.
