Google Professional Cloud Database Engineer Exam - Topic 5 Question 28 Discussion

You want to migrate an existing on-premises application to Google Cloud. Your application supports semi-structured data ingested from 100,000 sensors, and each sensor sends 10 readings per second from manufacturing plants. You need to make this data available for real-time monitoring and analysis. What should you do?
A) Deploy the database using Cloud SQL.
B) Use BigQuery, and load data in batches.
C) C.Deploy the database using Bigtable.
D) Deploy the database using Cloud Spanner.

Definitely not Cloud SQL, it can't handle that scale.

Cloud Spanner sounds appealing because it’s scalable and supports real-time data, but I’m worried about the complexity of managing it.

I feel like Bigtable could be a good choice since it’s designed for high throughput and low latency, but I’m not completely certain.

I think BigQuery is great for analytics, but it’s more about batch processing, right? Not sure if it’s the best fit for real-time needs.

I remember we discussed that Cloud SQL might not handle the scale of 100,000 sensors effectively, so I’m leaning away from that option.

I feel pretty confident about this one. Based on the requirements, I would go with option D and deploy the database using Cloud Spanner. It's designed for high-throughput, low-latency applications, which seems perfect for this use case.

Okay, let me think this through. We need to handle a huge amount of data from 100,000 sensors, with 10 readings per second. That's a lot of data! I think the key here is to find a solution that can ingest and process this data in real-time, so I'm leaning towards option B with BigQuery.

Hmm, I'm a bit unsure about this one. The question mentions real-time monitoring and analysis, so I'm not sure if Bigtable is the best fit. Maybe I should look into the other options as well, like BigQuery or Cloud Spanner.

This seems like a pretty straightforward question. I'd go with option C and deploy the database using Bigtable. It's designed for handling large volumes of semi-structured data, which is exactly what we need here.

Hmm, I'm a bit confused. Increasing the network bandwidth to 2 Gbps or 10 Gbps seems like a lot of work. I'm leaning towards keeping the 1 Gbps link and doing an offline migration.

Wow, 100,000 sensors? That's a lot of data! I hope the person who has to manage that infrastructure gets paid well. Bigtable seems like the right choice to handle all that semi-structured goodness.

If I had a 100,000 sensors sending data at 10 readings per second, I'd be tempted to just use a rubber band and a paper clip to collect it all. But in all seriousness, Bigtable sounds like the way to go here.

BigQuery seems like the best option here. Dealing with semi-structured data from so many sensors and requiring real-time monitoring is a perfect use case for a data warehouse like BigQuery.
