The cloud computing market is huge with a massive scope of expansion. In a race of having the biggest market share, with many leading companies such as Azure<\/a>, Google Cloud<\/a>, providing cloud services, Amazon takes the lead.<\/p>\n\n\n\n

Amazon Web Services (AWS)<\/a>, having established itself as an early leader, owns almost half the world\u2019s cloud infrastructure market. Amazon reported revenues worth $15.4 Billion in 2018 and carried the dominance forward into 2019 with revenue of $16 billion (Q1 & Q2 combined). <\/p>\n\n\n\n

In Q4 2019, the global cloud infrastructure market\u2019s revenue amounted to $27 billion which brought the total revenue for the year to $96 billion. According to the reports of Synergy Research Group<\/a>, Amazon\u2019s market share, in 2019, amounted to 33% of the total worldwide public cloud infrastructure market.<\/p>\n\n\n\n

\"AWS<\/figure>\n\n\n\n

AWS provides many different services which can be the components of a serverless application \u2013 AWS Lambda<\/a>, API Gateway<\/a>, S3<\/a>, DynamoDB<\/a>, SNS (Simple notification service)<\/a>, SQS (Simple queue service)<\/a>, AWS Step Functions<\/a>, CloudWatch Events <\/a>and Amazon Kinesi<\/a>s.<\/p>\n\n\n\n

The focus amongst AWS serverless services is AWS Lambda<\/a>, which is the compute layer of the serverless app development, where the code is executed. AWS development tools and services enable best practices while building and maintaining the serverless application with Lambda.<\/p>\n\n\n\n

AWS Lambda: An overview<\/strong><\/h2><\/p>\n\n\n\n

AWS Lambda<\/a> is a high-scale, event-driven, provision-free serverless compute, that allows you to run code without any wastage of resources. It provides the cloud logic layer for the apps. AWS Lambda functions are triggered by different events that occur on AWS or any third-party services, which enables developers to build apps. When an event occurs, the code is executed and the required operations are carried out by the code. When there are multiple events occurring simultaneously, more copies of the functions are run parallelly by Lambda. Each request is scaled precisely which reduces the wasted capacity. Moreover, you pay only for the resources used or the compute time consumed.<\/p>\n\n\n\n

Lambda can also be described as FaaS (Function as a Service), where the vendor provides provision-free scalability and built-in reliability and there are no virtual machines present. With Lambda, you can virtually run code for any type of app or backend service.<\/p>\n\n\n\n

Each Lambda function that is created contains the code that needs to be executed, the configuration that defines the execution and event sources which detect and invoke the functions when they occur. For example, it runs code in response to HTTP requests with API Gateway, it runs code in response to the data changes with S3 bucket or DynamoDB table, it invokes code using API Calls made with AWS SDK<\/a>s, and there are many more. Many event source options can trigger aws lambda function.<\/p>\n\n\n\n

You can just upload the code and enter configuration \u2013 when and how to invoke \u2013 and Lambda will take care of everything else that\u2019s required to run the code with high-availability.<\/p>\n\n\n\n
