![]() When using Function as a Service (FaaS) such as AWS Lambda, you don’t need to compile your application – just insert your code in the interface provided by MSP (managed service provider). On the Platform as a Service (PaaS) level, you can run your application that must be compiled before running. When using Infrastructure as a service (IaaS) such as AWS EC2, you can manage operating systems on provided virtual machines (EC2 instances). Thus, when using physical servers, you can manage hardware and all upper levels. The lowest levels (required user management) are marked with a green color and the upper levels (provided provider management) are marked with a blue color. ![]() On the table below, you can see the level of management for each service type starting from using physical servers and compare them. After configuring a function to run when an event occurs, your application will be executed automatically after each new event.Īs for classification, Lambda is an implementation of Function as a Service (FaaS) by Amazon. This way, you can focus on your application, not on server management-this is why AWS Lambda is referred to as serverless.Īn event after which your application is executed can be uploading a file to the Amazon S3 bucket, making changes in DynamoDB tables, getting an HTTP request to the API Gateway service, etc. Just insert your program code (called Lambda function in this case) in the AWS Lambda interface, associate the Lambda function with the event and run the application in the cloud when needed, without taking care of server management and environment configuration. You don’t need to configure a virtual server and environment to run an application you have written. What Is AWS Lambda?ĪWS Lambda is a computing platform that allows you to run a piece of code written on one of the supported programming languages – Java, JavaScript, or Python when a trigger linked to an event is fired. AWS EC2 can be used for cloud hosting – you can deploy servers as virtual machines (instances) in the cloud. The category of AWS EC2 web service is known as Infrastructure as a Service. Manage everything you need and fully control your EC2 instances including rebooting and shutting down the instance. You have the root access for your Amazon EC2 instances and can create additional users. You can select the base image with the necessary pre-installed operating system (OS) such as Linux or Windows and then configure most OS settings as well as installing custom applications. You can change the amount of disk space, CPU performance, memory etc. AWS EC2 (Amazon Web Services Elastic Compute Cloud) is a service that allows for using virtual machines called EC2 instances in the cloud and providing scalability.
