Leverage Azure Primum SSD @ Low Cost

Interesting and surprising correct, how SSD can be cost-effective when compared with Standard Tier. Absolutely this will raise some eyebrows, Let’s see how and when we can use azure blob storage to optimize our storage spend.

Let’s take an example you are running your image sharing or media sharing platform, if you look broadly for image sharing on a website you would need really low latency for your thumbnails to load than the actual file size. So when building solutions to leverage blob storage, it is critical to categorize your workload based on latency and transaction need. in this case, you should leverage SSD for your thumbnail and SSD for your large files. this way you would get a low cost for thumbnail storage with a superious user experience.

If your workload has a high transaction requirement, it really makes sense to use SSD than Standard storage, because, with SSD, you would reduce your transaction cost and get much better latency and may see a spike in storage cost but if drill down you would pay much less.

Azure storage Cost drivers

Capacity — with standard storage you would be less for storage but much high on transactions

Transactions — Transaction cost is less with SSD

Redundancy — This depends on your workload

Network — This is also important to note, default all your routing goes from your base location, let’s understand this better. If you have storage in EastUS2 and you are working from an office in APAC, default call routing is via APAC>EUS2, if you have the flexibility to route traffic directly to EUS2 and avoid that additional hop, you would see improved performance.

What are other ways to optimize blob storage:

1) Storage Reservation: Storage Reservation can help you save almost 38% of the total cost if you have a predictable workload for 1 to 3 years.

2) Life Cycle Policy: This is again a very important point to consider for a bigger workload like Azure Data Lake G2 kind of storage. not all files you would be accessing frequently. if you can add a rule like files that are not modified for 90 days, move to cold storage or unmodified files for 180 days to move to Archive storage and last untouched files for 2 years for 5 years just delete.

Note: Azure Lifecycle Policy, ensure and understand your workload in depth because calling file form archive and cool tier can be expensive.
