Wondering what you can do with @serverlessq? Here's a common use case:

Resizing images after uploading them, with the help of @vercel and @supabase.

Read on to find out how we did it: 🧵 Image Resizing:

📷 Digital apps rely on images, but large images can slow down apps and frustrate users.

Resizing images optimizes app performance and enhance user experience. If you're a web developer, you know the importance of optimizing image size, especially for SEO.

You don't want to wait for your customers to tell you when something is wrong with your system. CloudWatch Alarms can alert you to abnormal behavior before it affects your users.

Here are some important details about CloudWatch Alarms you need to know👇🧵 1/ 🚨 CloudWatch Alarms notify you when a system or service reaches a pre-defined threshold like errors or usage.

Alarms act on top of pre-defined metric thresholds, like Lambda Errors.

This thread compares different models of building event-driven systems for @hashnode on AWS

• A queueing model with SQS
• Fanout with SNS
• Event Bus with EventBridge

One of the main benefits still is ➡️ Decoupling Systems

The example shows a tight coupling example. The API needs to know 𝐞𝐯𝐞𝐫𝐲𝐭𝐡𝐢𝐧𝐠 which can get quite complex if you introduce failure handling & retries.

One of the main building blogs in learning AWS is the service 🥁🥁 CloudWatch!

It is the centralised logging service on AWS

Let's have a look at the basic concept CloudWatch Logs is following 🧵 𝐂𝐞𝐧𝐭𝐫𝐚𝐥𝐢𝐬𝐞𝐝 𝐋𝐨𝐠𝐠𝐢𝐧𝐠 𝐒𝐞𝐫𝐯𝐢𝐜𝐞 📝

Many services are logging directly to CloudWatch

For example
• API Gateway
• Lambda
• ECS
any many more!

Having all logs in 1️⃣ place is an immense benefit compared to having the logs separated on different machines

• Document: Complex types like lists and maps
• Set: Lists of the similar scalar

Build a simple serverless web application.

Services used:
• Amplify Hosting
• API Gateway
• Lambda
• S3
• Rekognition
• DynamoDB

Almost every cloud application uses AWS SNS, SQS, or a combination of both.

Let's see what these services are, how they are different from each other, and what some good use cases are.

Let's go 🚀 🧵

SNS is the pub/sub-service of AWS. It allows sending messages to topics.

Consumers can subscribe to topics and decide if they want to receive messages or not.

The messages get fanned out to many subscribers at the same time.

CDK is an awesome tool for building your cloud apps.

It is often hard to understand, so let's go through some basics:

🔸 Version 2 News

Let's go 🧵 👍🏽 𝗕𝗲𝗻𝗲𝗳𝗶𝘁𝘀

The main value of CDK is to use a proper programing language instead of configuration (YAML or JSON) files.

You have several benefits with that:
🔸 Programming constructs (if, while, etc.)
🔸 Familiar IDE (Vs Code ftw)
🔸 Reuse code ability
