AWS Lambda vs EC2 Understand the key differences to choose the right cloud service.

AWS Lambda and EC2 are two popular services provided by Amazon Web Services AWS that offer different ways to run and manage applications in the cloud. Lets break down the key differences between AWS Lambda and EC2 to help you decide which one is right for your needs.1. Lambda is serverless, while EC2 requires managing virtual serversAWS Lambda is a serverless computing service, which means you dont have to worry about managing servers or infrastructure. With Lambda, you simply upload your code, and AWS takes care of running and scaling it automatically. This makes it easy to quickly deploy code without provisioning servers or worrying about maintenance.On the other hand, Amazon EC2 Elastic Compute Cloud is a service that allows you to launch and manage virtual servers in the cloud. With EC2, you have full control over the server environment, including the operating system, networking, and security settings. This gives you more flexibility but also requires more effort to manage and scale the servers yourself.2. Lambda is eventdriven, while EC2 is always runningAWS Lambda is designed to run code in response to events, such as HTTP requests, file uploads, or database changes. This eventdriven architecture allows you to create functions that are triggered by specific events, making it ideal for building serverless applications that respond to realtime data.On the other hand, Amazon EC2 instances are always running and can be used for a wide range of applications, such as running web servers, databases, or batch processing jobs. EC2 instances are persistent, meaning they can run continuously and handle a steady workload over time.3. Lambda is payperuse, while EC2 is payperhourWith AWS Lambda, you only pay for the compute time your functions consume, rounded up to the nearest 100 milliseconds. This payperuse pricing model allows you to run code without paying for idle server time, making it costeffective for applications with unpredictable or sporadic workloads.On the other hand, Amazon EC2 uses a payperhour pricing model, where you are billed for the time your instances are running, regardless of how much compute power they are using. While EC2 offers more control over server resources, it can be more expensive for applications that require constant or high levels of compute power.4. Lambda has resource limitations, while EC2 offers more flexibilityAWS Lambda imposes resource limitations on memory, execution time, and temporary storage for each function. While these limits are generally sufficient for most use cases, they can be a constraint for applications that require large amounts of memory or longrunning processes.Amazon EC2 instances, on the other hand, offer more flexibility in terms of customizing the server resources to meet your specific requirements. With EC2, you can choose the instance type, storage capacity, and networking configuration that best suits your applications needs.In conclusion, AWS Lambda and EC2 offer different ways to run and manage applications in the cloud, each with its own strengths and limitations. If you are looking for a serverless solution that is easy to deploy and scale, AWS Lambda may be the right choice for you. If you need more control over your server environment and resources, Amazon EC2 might be a better fit. Ultimately, the decision between AWS Lambda and EC2 will depend on your specific requirements, budget, and technical expertise.
