Explain the concept of software scalability.

Software scalability refers to a system's ability to handle increasing loads or demands by efficiently expanding its resources. It’s a critical aspect of software architecture and design, ensuring that an application can grow and perform well as its usage, data volume, or transaction rate increases. Here’s a detailed explanation of the concept:

Types of Scalability

1. Vertical Scalability (Scaling Up)

   • Description: Involves adding more power to a single server, such as increasing CPU, RAM, or storage capacity.
   • Example: Upgrading a server from 16 GB of RAM to 64 GB to handle more data processing.
   • Advantages:
     • Simpler implementation.
     • Often requires minimal changes to the software.
   • Limitations:
     • Limited by the maximum capacity of a single machine.
     • Can become expensive.
