Answer: AWS Lambda is a serverless service from Amazon Web Services (AWS) that allows developers to run code without managing servers or processes.
Q2: How does AWS Lambda work?
Answer: Developers can write code in their favorite language, such as Python, Java, or Node.js, and submit it to AWS Lambda. Users only pay for compute time used during uptime and do not need to pay for idle time.
Q3: How do you monitor the performance of your AWS Lambda functions?
Answer: AWS Lambda offers a variety of monitoring tools, including Amazon CloudWatch Logs, which allows users to monitor and troubleshoot Lambda functions. Users can also set up custom metrics and alerts to monitor performance metrics.
Q4: How secure is AWS Lambda?
Answer: AWS Lambda has many security features such as VPC support, IAM roles and policies, and access at rest and in transit. Users can also integrate AWS Lambda with AWS Key Management Service (KMS) to manage encryption keys.
Q5: Can you explain the limitations of AWS Lambda?
Answer: AWS Lambda has some limitations, such as a maximum processing time of 15 minutes, a maximum export package size of 50MB, and a maximum distribution size of 3GB.
Q6: Can you explain AWS Lambda and what it does?
Answer: AWS Lambda is a serverless service that allows developers to run their code without planning or managing servers. It is an event-driven service that executes code in response to events such as changes in data or user activity. This allows developers to focus on writing code rather than managing the process.
Q7: How does AWS Lambda pricing work?
Answer: AWS Lambda pricing is based on number of requests and processing time.
You are charged for the number of requests you make to your lambda function and the time it takes to run your code. There are no charges when your account is inactive.
Q8: What are the advantages of using AWS Lambda?
Answer: AWS Lambda has many benefits, including autoscaling, reduced workloads, and increased scalability. It also provides cost savings by eliminating the need for servers and reducing time spent on property management.
Q9: Can you explain the difference between AWS Lambda and EC2?
Answer: AWS Lambda is a serverless service that allows developers to run code without managing servers, while EC2 is a virtual server that requires developers to manage the underlying operations. Lambda is event driven and charges based on usage, while EC2 charges based on server uptime.
Q10: How do I monitor an AWS Lambda function?
Answer: AWS Lambda has many monitoring features such as CloudWatch Metrics, CloudWatch Logs, and X-Ray.
