- In this video, I have discussed the AWS Lambda Service concurrency. Using an analogy of a restaurant I have elaborated the difference between Unreserved, Reserved, and Provisioned Concurrency. Mainly, I have addressed the following questions:-
What is AWS Lambda Service Concurrency
What is the difference between the Reserved and Provisioned Concurrency of Lambda functions?
What are some use cases for choosing either Reserved or Provisioned concurrency?
To summarise: The Reserved concurrency represents the maximum number of concurrent instances allocated to your function. When a function has reserved concurrency, no other function can use that concurrency. Configuring reserved concurrency for a function incurs no additional charges.
And, the Provisioned concurrency is the number of pre-initialized execution environments allocated to your function. These execution environments are ready to respond immediately to incoming function requests. Configuring provisioned concurrency incurs additional charges to your AWS account.
At the end of the video, I give a practical demo of how to configure the Reserved and Provisioned Concurrency of a Lambda function using AWS Management Console.

Great explaination...make complex topic easy to understand
Great explanation. Exactly, what I needed to understand.
Well explained 🎉
Very well explained with an analogy. Appreciate it
Glad you liked it
very nice explanation... Thank u
You are most welcome
Simple and short. I liked this video so much bcoz it didnt just explain also gave the example and that help me to visualize the use case. 👏👏👏
Thanks for the lovely feedback Jay :-)
Good job bahi jaan
