Answer: Use regional managed instance groups and a global load balancer to increase performance because the regional managed instance group can grow instances in each region separately based on traffic.
Option A is the correct answer. Using regional managed instance groups (MIGs) in conjunction with a global load balancer (GLB) helps distribute the traffic efficiently across multiple regions. This setup allows the regional managed instance groups to scale instances based on traffic within each region independently, thus improving performance. The global load balancer ensures that user requests are directed to the closest available instance, further reducing latency. This approach effectively addresses Dress4Win's need to optimize their architecture for performance and distribute it across multiple locations in the cloud.

Dress4Win is a web-based company that helps users organize and manage their personal wardrobe using a website and mobile application. The company has experienced rapid growth, and its infrastructure, currently located in a single data center, is now insufficient. This has led to high latency for some customers. As part of their plan to migrate to Google Cloud Platform, Dress4Win wants to evaluate and optimize their system for performance in the cloud by distributing its architecture to multiple locations. Which approach should they use?
A
Use regional managed instance groups and a global load balancer to increase performance because the regional managed instance group can grow instances in each region separately based on traffic.
B
Use a global load balancer with a set of virtual machines that forward the requests to a closer group of virtual machines managed by your operations team.
C
Use regional managed instance groups and a global load balancer to increase reliability by providing automatic failover between zones in different regions.
D
Use a global load balancer with a set of virtual machines that forward the requests to a closer group of virtual machines as part of a separate managed instance groups.
