System design solution is judged on

• simplicity — how simple is the solution

• fedility — how can it be altered in future

• cost requirement — what is the cost requirement for this

For any solution the best solution is to use an existing solution

the code can be deployed at

• local machine vs cloud service providers

• server or serverless

  • server will have a dedicated server for them while the serverless will not have a dedicated server for this.

  • for server it is cheaper and faster but is costlier as serverless we don't have to manage the resource but it takes time to scale up.

Where are the pages --

• perform operations

  • login

  • register

  • create a new account

• we can store these pages into our server / serverless or on a CDN

  • using CDN to serve static files is obvious as those are same for all the users as users will have a low latency as this content will be served to the users by the nearest server.

  • CDNs are used for the static pages as we don't have to update the values in our backend, but when we have a lot of updation going on then serving them using the CDN is a bad idea as the updation may take time due to location.

• to serve the content using the CDN we have a folder which is being checked by the CDN every 10 second.and gets updated, this updated content is served to the users.

• DNS —
