Differences Between Azure Block Blob And Page Blob?

Azure Blob Storage is like a big storage space in Microsoft’s cloud where you can keep different types of data. Inside this storage, there are two main types of blobs: Block Blob and Page Blob. In this article, we will see the difference between the two types of Azure Blob Storage.

Block Blob

Block Blob is great for storing large chunks of data that you read or write in order, like when you’re watching a video online or saving backups. It’s like putting together blocks of information, and you can add or change these blocks easily.

Page Blob

Page Blob is better when you need to read or write data in random places, not just in order. It’s like having a big book where you can quickly flip to any page you want. This is useful for things like virtual hard drives or databases where you might need to jump around a lot.

Benefits Of Azure Blob And Page Blob

Azure Blob Storage provides numerous benefits for storing both structured and unstructured data in the cloud. The following are the benefits that both Block Blob and Page Blob offer:

• Scalability: You can easily increase the storage space as you need more room.
• Durability: Your data is stored in many places, so it’s safe even if something goes wrong.
• Cost-effectiveness: You can choose pricing options that fit how much you use.

When To Choose Azure Blob And Page Blob

• Block Blob: This Azure Block Blob Storage is ideal for storing data that can be read or written sequentially such as videos, backups or log files. It supports large files and streaming scenarios.
• Page Blob: This service can be choosable when you need to access the data randomly in common scenarios like virtual hard drives or databases. It enables the random read and write operations at the page level.
