Blockchain Smart Contract Theory Behind

The smart contract in Blockchain is a kind of software application that works without human intervention based on the transaction logs and provide a solution to the user request. 
I want to share the back end mechanism in the Smart Contract of Blockchain.

AWS: Block Vs Object Storage Real Differences

Block and Object are two popular storages in AWS. Storage is the main task in the cloud environment. 

I have given the list of differences for your quick reference.

Object vs Block Storage

Why these names are different. Firstly, you need to understand storages available in AWS. 

You already know that AWS is leader in cloud computing.
object vs block storage

Object Storage

  • Object means it is a single object. You are not dividing here.
  • In the context of AWS, object storage helps your file to store as -is. How big it is does not matter.
  • Suppose, your file size is 10MB, it stores as 10 MB file.
  • What happens when you update a 30MB file, simply, it deletes old object and create a brand new object.
  • Even, for small change, you need to update whole file. So, it utlilizes lot of resources. 
  • Object storage is much better for big file and very few changes.
  • The object storage is well managed by AWS .
  • AWS has full control over Object storage.

Block Storage

  • Block storage divides your file into blocks.
  • You have selected a block size as 512 bytes, then you want to upload 10MB file, it then, divides the whole file to 20 blocks.
  • When you want to update a single character, it updates only that Block. It will not touch other blocks.
  • You can save network and bandwidth use in Block storage.
  • When the changes are more, and you want to update very often, then Block storage is much better.
  • In Block storage volumes are mountable.
  • AWS has no visibility on blocks inside of Block storage.
  • It has visibility only on Block volumes.
