The name is derived from functions in lambda calculus and programming, which act as a good analogy for the service. In Lambda, you can write a function and connect it to other services, such as API Gateway, S3, Kinesis, EC2, etc.<\/p>\n
What are the 3 components of AWS Lambda <\/h3>\n
AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers. Lambda handles all the administration of the underlying infrastructure, so you can focus on building your applications.<\/p>\n
There are three components to AWS Lambda:<\/p>\n
A function: This is the actual code that performs the task.
\nA configuration: This specifies how your function is executed.
\nAn event source (optional): This is the event that triggers the function. You can trigger with several AWS services or a third-party service.<\/p>\n
In short, a serverless function is the same as a Lambda function. The term “serverless” simply refers to the fact that these functions are executed without the need for a server. Instead, they are run on a platform-as-a-service (PaaS) such as AWS Lambda. The serverless framework is a tool that can be used to build and deploy serverless functions.<\/p>\n
What is Lambda and serverless? <\/h2>\n
AWS Lambda is a great way to run code for virtually any type of application or backend service without provisioning or managing servers. You can trigger Lambda from over 200 AWS services and software as a service (SaaS) applications, and only pay for what you use.<\/p>\n
The Disadvantages of Lambda Architecture:<\/p>\n
1. Since all data is append-only and no data in the batch layer is discarded, the cost of scaling will necessarily grow with time.<\/p>\n
2. Others have noted the challenge of maintaining two separate sets of code to compute views for the batch layer and the speed layer.<\/p>\n
