Extract text from images using Amazon Bedrock & .NET
In today's digital age, vast amounts of information are exchanged in various formats, including images. However, the text embedded within images is often inaccessible for search engines, text analysis tools, and other digital applications. This limitation has given rise to the need for extracting text from images, a process that involves identifying and recognizing the textual content present within an image file.
Handling Partial Batch Failure When Processing SQS Messages with a Lambda Function
Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. One common use case for SQS is to process messages from a queue as a batch using a Lambda function. However, in some cases, you may encounter partial batch failure, where some messages in the batch are processed successfully, while others fail. In this case, you need to handle the partial batch failure to ensure that the messages that failed to process are retried, while the messages that succeeded are not processed again.
Create custom project template in Visual Studio

Run .NET Lambda Function Locally Using LocalStack
AWS Toolkit for Visual Studio makes it easier for developers to develop and debug Lambda functions locally but for actual Lambda integration test, we need to deploy Lambda function in AWS account.
Amazon SQS local development using LocalStack
Amazon SQS is a reliable, highly-scalable hosted queue for storing messages as they travel between applications or microservices. Amazon SQS moves data between distributed application components and helps you decouple these components. That means to test your application you will need to connect to the Amazon SQS service each time. For development and testing purposes, you’ll likely want to test locally.
Amazon S3 local development using LocalStack
It's always a good practice, before moving your code into cloud, do integration test from local dev environment. Let's say if you don't have AWS account access from your development machine Or you don't want to create resources in AWS account just for integration testing purpose in that situation LocalStack is best choice.
Reducing complexity and enhance readability of C# unit tests using AutoFixture
Unit tests allows developers to verify their code to make sure that the code works as expected and to identify and fix bugs at early stage. The goal of unit test is to isolate each part of the program and test them individually. When we write Unit Tests for individual code, we mock all external dependencies. The purpose of mocking is to isolate the code being tested without affecting the behavior or state of external dependencies.
API Load Testing using .NET NBomber
NBomber is an open source load testing framework which help .NET developers to load test their applications. NBomber is a lightweight framework for writing load tests which you can use to test literally any system and simulate any production workload. With NBomber you can test any PULL or PUSH system (HTTP, WebSockets, GraphQl, gRPC, SQL Database, MongoDb, Redis etc).
