AWS Lambda Reviews and details

Social recommendations and mentions

• Is FaaS the Same as Serverless?

  FaaS is specifically focused on building and running applications as a set of independent functions or microservices. Major cloud providers like AWS (Lambda), Microsoft Azure (Functions), and Google Cloud (Cloud Functions) offer FaaS platforms that allow developers to write and deploy individual functions without managing the underlying infrastructure. - Source: dev.to / 4 days ago

• How To Reduce Operational Costs With AWS Lambda

  So AWS Lambda is basically a serverless computing service that is offered by AWS. It enables developers to run the code in response to various events. It protects the developers from the pain of managing the servers. Using a serverless execution model helps the developers to handle provision, manage and scale the servers automatically. Through this approach the developers can fully focus on writing the code... - Source: dev.to / 17 days ago

• The 2024 Web Hosting Report

  The first product that popularized the term “serverless” was AWS Lambda, which is both the prototypical and archetypical function as a service provider. It also has a great name, which pings back to its envisioned place in the cloud of the future. In computer programming, a lambda, often referred to as a lambda function or lambda expression, is a concise way to represent an anonymous function, which is a function... - Source: dev.to / 2 months ago

• Use custom rules to validate your compliance

  You can build a custom config rules in 2 ways, using AWS Lambda and CloudFormation Guard. Lambda gives you a lot of flexibility, but it also brings complexity of maintaining. CloudFormation Guard is a bit more lightweight in that regard. Yes, you still need to maintain the logic to determine when your resource is compliant or not. But you need to do this in both cases, thus my go to preference is CloudFormation... - Source: dev.to / 3 months ago

• Serverless Site Health Check Notification System

  This blog details how you can use some key serverless components from AWS like Amazon Eventbridge, AWS Lambda, and Simple Notification Service to setup a system that will monitor your site (which can be running anywhere) and send emails, text messages, slack messages, and more when the reachability status of your site changes. - Source: dev.to / 4 months ago

• Refactoring a serverless application to use Step Functions third-party API call integration

  I use the OpenWeather API to receive the current temperature data by providing the latitude and longitude coordinates as query strings in the request. A Lambda function invokes the weather API and sends the current temperature value as a custom metric to CloudWatch. I then graph the temperature values on a dashboard and activate an alarm when the temperature sinks below zero degrees Celsius. - Source: dev.to / 4 months ago

• Starting My AWS Certification Journey as a Certified Cloud Practitioner

  After two years, I moved to a Web3 startup where I was given a lead software engineer role. This new role gave me more hands-on experience with AWS, where I've learned to implement serverless technologies like Lambda and DynamoDB. - Source: dev.to / 5 months ago

• Controlling access to IAM-protected API endpoints with Cognito groups

  I discussed a way to control access to endpoints using JSON web tokens and a Lambda authorizer earlier. - Source: dev.to / 6 months ago

• Build a Serverless Application for entity detection on AWS

  In this blog post, you will learn how to build a Serverless solution for entity detection using Amazon Comprehend, AWS Lambda and the Go programming language. - Source: dev.to / 7 months ago

• Deployment (GitHub actions, Bitbucket pipelines), the stupid way

  3 — This .env file will be sent with other files to the selected destination (in that case they will send environment variables to AWS lambda). - Source: dev.to / 7 months ago

• Authenticating users in the load balancer with Cognito

  Say that we have an application running behind a public-facing Application Load Balancer (ALB). The load balancer's target can be any supported target, including ECS containers, EC2 instances or even Lambda functions. Because the application is only available to authenticated users, we want to find a solution to identify them. - Source: dev.to / 7 months ago

• Implementing access control on API Gateway endpoints with ID tokens

  As mentioned above, the application will have two REST APIs set up in API Gateway. The endpoint handlers are Lambda functions. - Source: dev.to / 7 months ago

• Different ways to invoke AWS Lambda Functions

  AWS Lambda is a Serverless, event-driven compute service that lets you run code for virtually any type of application or backend service without provisioning or managing servers. You can trigger Lambda from over 200 AWS services and software-as-a-service (SaaS) applications and only pay for what you use. - Source: dev.to / 8 months ago

• Handling Massive Fan-out with AWS Lambdas

  AWS Lambda is a serverless compute service that allows developers to run their code without having to manage the underlying infrastructure. With Lambda, developers can upload their code and the service takes care of scaling, provisioning, and managing the servers required to run the code. - Source: dev.to / 8 months ago

• Programmatically reacting to S3 bucket external access exposures

  Luckily, we can set up a simple monitoring service, which uses a scheduled EventBridge rule and a simple Lambda function. - Source: dev.to / 8 months ago

• Receiving Slack notifications when CloudTrail logging gets turned off

  After logging has stopped, EventBridge will route a message to a dedicated Slack channel with the user's name, account number and the time of the event. Optionally, it will also invoke a Lambda function, which will re-enable logging in CloudTrail. - Source: dev.to / 9 months ago

• Using Golang for your AWS Lambda Functions

  I was sparked on a XKE to do a short experiment with using Golang for my AWS Lambda Functions. The trigger for this was something my colleague Mark van Holsteijn said. We where talking about sustainability. During this talk Mark made the comment that we should drop Python for our functions then. (He also recently wrote a blog on Golang using Golang for custom providers.). - Source: dev.to / 9 months ago

• Returning customized content based on location with S3 Object Lambda

  It will be a supporting access point, and the Lambda function will use it to retrieve the object from S3 via a pre-signed URL. Lambda will receive the URL as an input, and the application needs to call the endpoint. - Source: dev.to / 9 months ago

• Programmatically retrieving secrets from Parameter Store and Secrets Manager

  Below I'll discuss some ways we can make them available in our Lambda functions. I'll refer to passwords, connection URLs, and API keys as secrets in the rest of this writing to be brief. - Source: dev.to / 9 months ago

• Returning large objects from Lambda functions using stream responses

  Everything works well for Bob in his application, which consists of an API Gateway and some Lambda functions. - Source: dev.to / 10 months ago

• Debugging SQS subscription issues to topics

  The task is to subscribe the queue to the topic. To continue with the serverless momentum, assume that a Lambda function polls the queue and does something with the message. - Source: dev.to / 10 months ago
