What is best architecture to store images for blog and retrieval? I have a usecase where I have to design image storage / retrieval system for articles. Where and how should I store store these images and retrieve / access those while displaying contents of article with minimum latency?
It would be great if you can provide any reference for this. Thanks.
If you want minimum latency for image retrieval, you need to use a CDN (Content Delivery Network)
Check out this article for more details.
For example, AWS offers Cloud Front which is very simple to use - store the images into an S3 bucket, and then use dedicated CloudFront URLs on your client-side code, to fetch the images.
There are other CDN providers out there, you can find them right away on a Google search.
