According to Google Cloud documentation on Application Performance Management (APM), Cloud Profiler is the most effective tool for identifying resource-intensive parts of an application's source code. For Altostrat's Java-based media processing pipeline, which likely involves CPU-intensive tasks such as metadata extraction or transcoding, understanding exactly which methods or lines of code consume the most CPU or memory is critical.

Cloud Profiler is a statistical, low-overhead profiler that continuously gathers performance data (CPU usage, heap allocation, etc.) from production applications with less than 0.5% impact on performance. It presents this data in an interactive flame graph, allowing developers to pinpoint bottlenecks in the media processing logic.

While Cloud Trace (Option C) is excellent for monitoring latency across distributed services, it primarily tracks the "outer shell" of the request—showing how long a function took to execute or how long an external API call lasted—but does not provide the deep, code-level insight into internal Java method execution that Profiler does. Cloud Logging (Option A) is useful for troubleshooting specific events but is not a performance analysis tool, and Snapshot Debugger (Option D) is designed for inspecting variables at specific execution points rather than aggregate performance profiling. Given Altostrat's goal to "Optimize cloud storage costs" and "Accelerate... operational workflows," using Cloud Profiler to create more efficient, less resource-hungry processing code is the architecturally sound choice.

D: Handling "Unable to connect on port 22" error message

Possible causes include:

There is no firewall rule allowing SSH access on the port. SSH access on port 22 is enabled on all Compute Engine instances by default. If you have disabled access, SSH from the Browser will not work. If you run sshd on a port other than 22, you need to enable the access to that port with a custom firewall rule.

The firewall rule allowing SSH access is enabled, but is not configured to allow connections from GCP Console services. Source IP addresses for browser-based SSH sessions are dynamically allocated by GCP Console and can vary from session to session.
