Macro Architecture: Introduction

Almost all modern systems run on multiple machines, which we call distributed applications or systems. Those systems need multiple machines due to the following reasons:

• Clients and data are distributed across many machines.

• A single machine can’t handle the load of some applications.

• Systems need to talk to other systems as part of their functionality.

A distributed architecture must be able to store long-living data, sometimes across multiple requests; process user requests, either in response to direct requests or some kind of a trigger; and combine the state and logic to carry out the user requests efficiently. Macro architecture sees the systems as units (components or services) and their interactions. ...
