Which Google Cloud resource provides web interface access to applications on a VM?

1. Google Load Balancer

2. VPC Firewall

3. Cloud Functions

4. Compute Engine Instance Group

The correct answer is: Google Load Balancer

The Google Load Balancer is a resource that provides a web interface for accessing applications hosted on Virtual Machines (VMs) within Google Cloud. By distributing incoming traffic across multiple instances of an application, the Load Balancer ensures that requests are handled efficiently and reliably. This enables the applications running on VMs to scale and maintain high availability, while seamlessly routing user requests to the appropriate VM based on availability and health. Using the Google Load Balancer, you can configure HTTP(S) load balancing, which automatically provisions the necessary configurations and services to ensure that users can access the applications through a single IP address or domain name. This simplifies the management of application traffic and provides essential features such as SSL termination, session affinity, and content-based routing. In contrast, other options do not provide web interface access to applications in the same capacity. The VPC Firewall primarily focuses on controlling access and securing network traffic rather than delivering web interface capabilities. Cloud Functions are serverless and designed for event-driven architecture but do not provide a direct interface for VM applications. Compute Engine Instance Groups manage collections of VM instances for load balancing but lack a direct interface itself. Thus, the Google Load Balancer stands out as the solution designed for providing web access to applications hosted on VMs.
