What is AWS Lambda?

AWS Lambda is a cloud-based software that enables users to run code in response to events without provisioning or managing servers. The software automatically manages compute resources and implements triggers based on events such as HTTP requests or file uploads. AWS Lambda supports multiple programming languages, including Python, Node.js, and Java, and integrates with various AWS services to automate workflows and build serverless applications. The software scales automatically based on demand, charges only for compute time consumed, and offers monitoring and logging through AWS CloudWatch. The primary business problem addressed by AWS Lambda is reducing infrastructure management overhead while allowing organizations to focus on application logic and event-driven processes.

AWS Lambda has been a key enabler for building scalable, event-driven services without the overhead of managing infrastructure. It integrates seamlessly into the wider AWS ecosystem, allowing us to move quickly, automate workflows, and focus on delivering value rather than maintaining servers. Reliability and scalability have been consistently strong.

Great to have infra sorted by aws, but lots of learning required to get it to work, plus more pricey than expected

About Company

Company Description

Amazon Web Services (AWS), established in 2006, is focused on providing essential infrastructure services to businesses globally in the form of cloud computing. The key advantage offered through cloud computing, particularly via AWS, is its capacity to shift fixed infrastructure expenses into flexible costs. Businesses have been able to forgo extensive planning and procurement of servers and other Information Technology (IT) resources, owing to AWS. AWS seeks to provide businesses with prompt and cost-effective access to resources using Amazon's expertise and economies of scale, as and when their business requires. Currently, AWS offers a robust, scalable, economic infrastructure platform on the cloud powering an extensive array of businesses worldwide.

AWS Lambda Likes & Dislikes

The biggest strength is its true serverless model no infrastructure management, automatic scaling, and tight integration with services like S3, API Gateway, CloudWatch, and IAM. Its particularly powerful for: Event-driven automation Lightweight APIs Security and operational workflows From a security engineering perspective, the ability to integrate with IAM and trigger functions based on events makes it extremely effective for automation and response use cases.

handles infra

- No need to manage cluster size or capacity, it does all the scaling for you - No need to do OS patching, that's a relief for admins and platform engineers - It integrates very well with a broad range of AWS services - Provides monitoring where logs integrate with CloudWatch

Cold starts can still be a challenge for latency-sensitive workloads, especially in less frequently used functions. Debugging and observability can also be fragmented without additional tooling, and managing permissions (IAM roles/policies) can become complex at scale.

lots of gotchas, and more expensive than expected

- If you have huge runtimes or packages then there is a noticeable latency - If you do concurrent operations then both complexity and cost jump up - There are some hard limits, like it times out at max 15min

AWS Lambda Simplifies Cloud Operations But Faces Latency With Large Runtimes
5.0
Mar 3, 2026
AWS Lambda allows us to do cloud operations like self-service, elasticity, managed runtime etc. without provisioning any infrastructure or resources. It's best for lightweight API's, event-driven backends, automations, workflows and more. You just provide the code and AWS runs it. It also supports multiple runtimes and packages. You can also leverage it for distributed apps as it supports cloud native architecture, and the plus is that you do not need to provision any servers or containers.

Cloud-Native Applications Benefit From Improved Performance and Security With AWS
5.0
Jan 30, 2026
It’s been a great tool for our team because of the features that it offers, supporting faster development, improved performance, and the enhanced security and cost efficiency is great. True serverless compute dramatically reduces admin overheads, and the ability to scale is a game changer to say the least. Hence why we've always been an advocate of using AWS for cloud native applications, rather than using it looking through the lens of how you build systems and applications on premise. It just isn't going to work that way anymore.

Very efficient and scalable for modern tech. It's great for lightweight, event-driven features, but it struggles when you're trying to move fast on traditional web builds.
