Vision AI Detect and classify multiple objects including the location of each object within the image. This allows taking pictures of single items or a group of items and categorizing the products much easier. With Vision API’s vision product search, retailers can create an engaging mobile experience that enables customers to upload a photo of an item and immediately see a list of similar items for purchase.

• Firebase:

Firebase is Google’s fully-managed platform for rapidly developing and deploying web and mobile applications.​ Firebase is an alternative to Google Cloud for users who want to focus on building and deploying their applications in a highly opinionated framework.​ Serverless and can scale to zero.

• Cloud Run:

Cloud Run abstracts away all infrastructure management by automatically scaling up and down from zero almost instantaneously—depending on traffic. Cloud Run only charges you for the exact resources you use.

• A) is Correct. Migration of apps based on VM to Compute Engine should be performed by using Migrate for Compute Engine.
• B) is Incorrect. Migration of Linux workloads to containers can be done by using Migrate for Anthos and GKE.
• C) is Incorrect. Migration of Microsoft IIS web applications to Windows containers on GKE can be done by using Migrate for Anthos and GKE.
• D) is Incorrect. Extraction of application specific elements from VMs can be done by using Migrate for Anthos and GKE.

Cloud Firestore: is a flexible, scalable database for mobile, web, and server development from Firebase and Google Cloud. Similar to Firebase Realtime Database, it keeps your data in-sync across client apps through real-time listeners and offers offline support for mobile and web so you can build responsive apps that work regardless of network latency or Internet connectivity.

Dedicated Interconnect provides direct physical connections between your on-premises network and Google's network. Dedicated Interconnect enables you to transfer large amounts of data between networks, which can be more cost-effective than purchasing additional bandwidth over the public internet. If you have high bandwidth needs, Dedicated Interconnect can be a cost-effective solution over Partner Interconnect. Choose a 10 Gbps or 100 Gbps pipe and connect directly to a Google location with Dedicated Interconnect.

Cloud Functions can be written in Node.js, Python, Go, Java, .NET, Ruby, and PHP programming languages, and are executed in language-specific runtimes.

Cloud Functions automatically spins up and back down in response to events (Scale to zero).

Charged only when it is being used, which fits the scenario of "not heavily used but cannot be eliminated due to critical business function, and near-zero cost".

Artifact Registry enables you to centrally store artifacts and build dependencies as part of an integrated Google Cloud experience. Artifact Registry integrates with Cloud Build and other continuous delivery and continuous integration systems to store packages from your builds. You can also store trusted dependencies that you use for builds and deployments. Artifact Registry provides a single location for storing and managing your packages and Docker container images and much more

Container Registry is only multi-regional but Artifact Registry supports multi regional or regional repositories.

Preemptible VMs ( Preemptible Virtual Machines ) are highly affordable, short-lived compute instances suitable for batch jobs and fault-tolerant workloads. Preemptible VMs offer the same machine types and options as regular compute instances and last for up to 24 hours. Supplement your regular VMs with lower-cost, preemptible instances to finish your compute-intensive work faster, saving you time and money. Hence, Preemptible Virtual Machines is the cheapest computing solution.

The approach is to create a Service Account and grant it the permissions the resources (e g. the VMs) need. Then you create the VMs to use the Service Account as their identity.

Resources have a single identity, usually a Service Account. You should create Service Accounts for each functionally|security equivalent resource.

Identities are bound to one or more roles. Roles correspond to one of our more service|API methods. Try to use predefined roles but you can create custom roles.

Cloud Spanner is a fully managed relational database with unlimited scale, strong consistency, and up to 99.999% availability for multi-regional instances. Spanner never needs to be paused for patches, backups, failovers, or even schema updates.

Cloud Spanner optimizes performance by automatically sharding the data based on request load and size of the data. As a result, you can spend less time worrying about how to scale your database and instead focus on scaling your business making it an excellent solution for scaling issues while continuing to use a company's SQL-like database.
