The world has come a long way from maintaining hardware in a big room full of servers to running CPU and memory-intensive applications in just one click. One of the main purposes of this transition is to enable developers and system engineers to concentrate more on applications and programs rather than maintaining the underlying infrastructure. The shift toward serverless computing is happening rapidly, and many tools and technologies have emerged to help. AWS, for one, has been consistently releasing new features to help users move toward serverless computing and virtualization — Lambda being one such example.
The History Behind Amazon Firecracker
AWS launched Lambda to run user applications or scripts in a serverless manner. Lambda executed functions without any overhead simply and efficiently. The introduction of AWS Fargate, which runs containers, further stressed on serverless architecture. Firecracker was developed using the language Rust as a way to enhance the backend implementation of AWS Lambda and AWS Fargate. Firecracker was developed with the goal to provide high security, isolation, flexibility, and an efficient run-time environment for Lambda and Fargate services.
