Blogging Service

Overview

The Blogging Service is a serverless application built with AWS CDK that allows users to submit and search for blog posts using AWS Lambda, Amazon SQS, and Amazon OpenSearch.

Architecture

• API Gateway: Entry point for HTTP requests.

  • POST /blogs: Triggers the Blog Submission Lambda Function.
  • GET /blogs/search: Triggers the Search Lambda Function.

• Lambda Functions:

  • Blog Submission Function: Sends new blogs to SQS.
  • Blog Processing Function: Processes SQS messages and writes to OpenSearch.
  • Search Function: Queries OpenSearch for blog data.

• SQS Queue: Buffers submissions for asynchronous processing.

• OpenSearch: Stores blog data for efficient retrieval.
