In this episode of 'Back To Basics', Venu explores server-side rendering (SSR) and its benefits for web application performance and SEO. He explains how SSR works, comparing it to client-side rendering, and demonstrates how AWS services, particularly AWS Amplify, can be used to build and host SSR-based web applications. Venu discusses the architectural components required for SSR applications on AWS, including S3, CloudFront, Route 53, Lambda, and various developer tools. He highlights how AWS Amplify simplifies the process by abstracting away complex components, allowing developers to focus on building their applications while achieving millisecond latency and improved SEO rankings.
