This is backend as a service built to implement instagram like service where one can follow other users, share photos, like photos and comment on photos.

• Each user has its own redis list having its 10 recent posts.
• Whenever, a user wants to access his feed he hits api which collects all the posts of his followees from redis and sends a response.

• We use Depot Storage with S3 for storage of images.
• Only the link of the image is stored onto database.
