Amazon QLDB — Pandemic Shenanigans
Hey Folks!! I have been working from the office for the past couple of months now and an interesting sketch note piqued my interest. I have pasted the sketch for easy reference. Jerry Hargrove sketched the sketch note for future Amazonians’ and it was an interesting visual. The sketch talked about quantum ledger databases and I will take a stab at explaining my learnings from the sketch. I have worked largely with Amazon Dynamo db (NoSQL) but reading about a quantum ledger database (QLDB) was a breath of fresh air.
Quantum is the smallest unit of any entity involved in an interaction. What QLDB essentially brings to the table is a fully managed and serverless database ledger which helps in maintaining a transparent, immutable, and cryptographically verifiable transactional log. A central trusted authority owns this log. Amazon QLDB tracks all application data changes and maintains a complete and verifiable history of changes. Data stored in traditional databases (SQL/NoSQL) can have data conflicts and manipulations. Lack of support for audit trials and automatic data encryption resulted in traditional databases making the risk of data being read or changed by hackers directly.
