• 5 Architecture Patterns Every Web Application Developer Should Understand

  AWS Lambda, Google Cloud Functions, and Azure Functions are the major serverless platforms. Serverless is strongest for applications with variable traffic patterns: an API that handles 10 requests per minute most of the day but spikes to 10,000 during a marketing campaign scales automatically without manual intervention. - Source: dev.to / 4 months ago

• The 80/20 of AWS (the services that actually matter)

  Lambda lets you run code without managing servers. You write a function, upload it to Lambda, and it runs whenever something triggers it. An HTTP request, a file landing in S3, a message hitting a queue, a scheduled timer. Lambda handles the scaling. If you get one request, it runs one copy. If you get ten thousand simultaneous requests, it runs ten thousand copies. - Source: dev.to / 5 months ago

• Launch Your First Serverless API: Hands-On with AWS Chalice on AWS Lambda

  If issues arise (e.g., permissions), check logs via chalice logs. For region-specific tips, browse AWS Lambda docs. - Source: dev.to / 12 months ago

• Choosing between EventBridge, SNS, and SQS for event-driven patterns

  When the event bus receives a matching event, EventBridge routes it to the assigned target, in this case, a Lambda function. - Source: dev.to / about 1 year ago

• Building MongoDB-based event-driven applications with DocumentDB

  A Lambda function will act as the endpoint integration and save new products to the database. - Source: dev.to / about 1 year ago

• Triggering multiple workflows with DynamoDB Streams

  I use Lambda functions whenever possible, so I’m excited that pairing DynamoDB Streams with Lambda presents many opportunities. - Source: dev.to / about 1 year ago

• 4 Cognito User Pools features you might not know about

  We can set up Cognito to trigger a Lambda function at various stages of the sign-up and sign-in processes. These functions can enrich both the ID token and the access token. - Source: dev.to / over 1 year ago

• Building a Real-Time Serverless Chat App with AWS: A Scalable Approach

  You will learn the following in this lesson: Learn how to set up AWS AppSync to handle messages in real time. This article explains how to store messages in DynamoDB, a NoSQL database that can grow as needed. This article explains how to use AWS Lambda to build your own business code. This article explains how to use React to make a simple front end that talks to the chat back end. By the end of this... - Source: dev.to / over 1 year ago

• Stop bringing old practices to the cloud

  This is often due to a lack of training and knowledge about cloud-native services or capabilities. Many legacy workloads were built on top of 3-tier architecture since this was the common way most IT/developers knew for many years. Architectures were centralized and monolithic, and organizations had to consider scale, and deploy enough compute resources, many times in advance, failing to predict spikes in... - Source: dev.to / over 1 year ago

• Parameter Management at Scale: How Multi-Region Configurations Saved My Application

  Without going into details, I enable versioning when I use Lambda. Each version makes the Lambda immutable, ensuring that code and configuration do not change once published. - Source: dev.to / almost 2 years ago

• Time to move on to Day 2 cloud operations

  On Day 1, it may be ok to take traditional architectures (such as manually maintaining VMs), but on Day 2 it is time to take the full benefit of cloud-native services. The easiest way is to replace any manual maintenance of infrastructure with managed services – in most cases, switching to a managed database, storage, or even load-balancers and API gateways, will provide a lot of benefits (such as lower... - Source: dev.to / almost 2 years ago

• One possible evolution of software development industry thanks to LLM

  Even if one day ChatGPT is able to "digest" a codebase of millions of lines, I think it will be inefficient to ask it to maintain it. My feeling is that it will be much more efficient to ask ChatGPT to write small, configurable and reusable components that can be connected together. A database component, a UI component, a session component... Small components that ChatGPT can easily create and maintain (we need... - Source: dev.to / about 2 years ago

• Using Verified Permissions with Cognito to control access to API endpoints

  AWS has recently published a new feature for Cognito. The release introduces the use of Amazon Verified Permissions (AVP) to securely manage access to REST-type API Gateway endpoints via a Lambda authorizer. - Source: dev.to / over 2 years ago

• Using API Gateway mapping templates for direct DynamoDB integrations

  I've been exploring architectures that utilize native integrations between AWS services lately. In this context, I aim to avoid provisioning Lambda functions solely for data transmission, following the use Lambda to transform and not transport principle. - Source: dev.to / over 2 years ago

• Using Step Functions to handle feature flags

  Luckily, we (and Bob) build serverless applications and use Lambda functions. AWS provides an extension that we can integrate with our function as a layer. - Source: dev.to / over 2 years ago

• Introduction to JavaScript: Empowering Web Development with Interactivity

  Versatility: JavaScript is not limited to web browsers. It's used in a variety of environments, including mobile app development (using frameworks like React Native), game development (using libraries like Phaser), and even serverless computing (using platforms like AWS Lambda). - Source: dev.to / over 2 years ago

• How to Calculate the Cost of Deploying Open-Source API Gateway on AWS?

  Multi-Cloud and Hybrid Environments: Amazon API Gateway excels in integrating with other AWS services like Lambda but is tightly coupled with the AWS ecosystem. Conversely, open-source gateways offer greater flexibility, enabling deployment across GCP, Azure, private clouds, or hybrid environments of these environments. - Source: dev.to / over 2 years ago

• Checklist for designing cloud-native applications – Part 1: Introduction

  Serverless / Functions-as-a-Service – Modern way to run various parts of applications. The underlying infrastructure is fully managed by the cloud provider (no need to deal with scaling or maintenance of the infrastructure). Considered as a vendor lock-in since there is no way to migrate between CSPs, due to the unique characteristics of each CSP's offering. Example of FaaS: AWS Lambda. - Source: dev.to / over 2 years ago

• Why choosing "Lift & Shift" is a bad migration strategy

  Horizontal scaling is one of the main benefits of the public cloud. Although it is possible to configure multiple VMs behind a load-balancer, with autoscaling capability, allowing adding or removing VMs according to the load on the application, legacy applications may not always support horizontal scaling, and even if they do support scale out (add more compute nodes), there is a very good chance they do not... - Source: dev.to / over 2 years ago
