Scale infrastructure

Servers infrastructure will define the possible future limitations we could have.

We must take into account architecture aspects as structure, relations, restrictions and interactions

Main resources that affect our applications are:

• processing: servers where application is stored and processed
• information: all data that is registered by the application (database)
• APIs: allow to separate functionalities of our applications (microservices)
• events: ease the asynchronous execution of the different parts of our application (event driven)
• content delivery: ease the user experience through CDNs an cache systems

We don't need over scaled infrastructure, it will result in unnecessary costs. We have to take into account that if we have a server with a processing capacity, two servers with half of the capacity will provide an efficiency of 130% compared to one server.
