Best Storage Tier for Storing 50+ Terabytes of Data with Low Latency and Cost Efficiency
Question
Joseph is a Cloud Data Engineer of a Construction company “Fabrikum Constructions Inc”
He needs to store more than 50 terabytes of data which requires the duration of storage for at least a month and requires a millisecond of latency and lower storage cost.
He considers Azure storage for this scenario.
What kind of storage tier should he consider?

Given the scenario, Joseph needs to store 50 terabytes of data for at least a month, with low storage cost and fast access time. Azure offers four storage tiers for Blob storage - Hot, Cool, Archive, and Premium - each designed to cater to different use cases.
The Azure Blob Hot tier is designed for frequently accessed data that requires fast access times and low latency. This tier is ideal for data that is accessed regularly and needs to be readily available at all times. However, the storage cost of the hot tier is higher than the other tiers.
The Azure Blob Cool tier is designed for data that is infrequently accessed but still requires fast access times. The cool tier offers lower storage costs than the hot tier but slightly slower access times. This tier is ideal for data that is accessed less frequently but still needs to be readily available.
The Azure Blob Archive tier is designed for data that is rarely accessed and can tolerate higher access latencies. This tier offers the lowest storage cost of all tiers but has the highest access latency. Data in the archive tier may take hours to access, making it unsuitable for frequently accessed data. This tier is ideal for data that needs to be stored for a long time and accessed rarely, such as compliance data, regulatory data, or backups.
Finally, the Azure Blob Premium performance tier is designed for data that requires the highest levels of performance and scalability. This tier offers the lowest latency and the highest throughput of all tiers, making it suitable for high-performance workloads that require fast access times and low latencies.
Given the scenario described, Joseph needs to store a large amount of data for at least a month with low storage cost and fast access times. Since the data needs to be accessed frequently and requires fast access times, Joseph should consider the Azure Blob Cool tier. The cool tier offers lower storage costs than the hot tier while still providing fast access times, making it the best fit for this scenario.
