Architectures of Platforms.

For web apps, an architecture means how are devices connected over the network.

There are mainly two types of web apps namely,

• Client-Server Architecture
• Peer-2-Peer Architecture

Client Server Architecture

• There is an explicit difference between the server and the client
• Machine clients are also available that do not need a user interaction to perform its task.

• There are several other variants of this architecture, i.e., multiple server, multiple client, multiple queue, etc.

• Examples: Emails, Messaging Apps, etc.

A pictoral representation of client-server architecture is given below.

Peer to Peer Architecture (P2P Model)

• All the devices connected to P2P are given same priority but some peers marked by masters are given higher priority.
• There are not owners of the network but masters or moderators are always present.
• The files are still encrypted with keys to only the owner.
• The information is shared.
• Examples: Web-3, Torrent Clients, IPFS, etc.

A pictoral representation of peer-2-peer architecture is given below.
