Your customer's IT team is in the process of modernizing their customer-facing applications. They've witnessed others getting good results from employing microservices, and they're keen to adopt it themselves. The first application that they are modernizing has about 5 different sub-parts, which they have identified will be the services. They also identify that each of them has different scale requirements - some services like user login are less frequently used while others like transac-tions are heavily used. What technical strategy would you recommend for them?

1. A. Containerize the services and orchestrate them with Google Kubernetes Engine.
2. B. Retain the original application in Compute Engine and scale it as needed using Managed Instance Groups.
3. C. Retain the original application as a backup and also for separately scaling the ser-vices, create new application binaries.
4. D. Retain the original application in Compute Engine and scale it as needed using Unmanaged Instance Groups.

Correct Answer: A
Containers and Kubernetes are ideal for the kind of requirement mentioned here - separate microservices that need to scale independently.
Google Kubernetes Engine (GKE) provides a managed environment for deploying, managing, and scaling your containerized applications using Google infrastructure. The GKE environment consists of multiple machines (specifically, Compute Engine instances) grouped together to form a cluster.
