Client-Server model
The client-server model is a distributed application structure with two roles. There are servers providing resources and clients requesting them. For example, a web-server follows the client server model. The user of the browser is the client and the server providing web-pages is the server.
Advantages
- A service that is centrally managed is easier to monitor.
- Easier to apply access controls and security to the system.
- With a centralised system you can gaurentee data integrity more easily.
Disadvantages
- Single point of failure if the server goes down.
- Higher start up cost as you require the infrastructure in the first place.
- Scaling can become complex as the server can become a big bottle neck.
