Types of Scalability

Overview

Recall that scalability in software architecture addresses a system’s ability to adapt to growing demands and increased workloads. There are several types of scalability that can be achieved in software architecture, including:

Horizontal scalability

Horizontal scalability involves adding more resources, such as servers or machines, to an existing system in order to increase its capacity and handle a larger workload. This approach is often used when the workload is distributed across multiple machines and can be easily distributed across additional machines as needed.

For example, a web application that receives a large number of requests can be scaled horizontally by adding more web servers to the system. This allows the application to handle the increased workload by distributing the requests across multiple servers.

Advantages

The advantages of this include:

• It allows a system to scale up to meet increased demand by adding more machines to the network rather than upgrading a single machine.
• It can be more flexible because it
