Load Balancing: Load balancing is the practice of distributing incoming network traffic across multiple servers to ensure efficient resource utilization and prevent overload on any single server. It's like having multiple cashiers at a store during peak hours to avoid long waiting lines.
Vertical Scaling: Vertical scaling involves increasing the capacity of an individual server or device by adding more resources such as CPU power, memory, or storage. It's like upgrading your computer with a faster processor or more RAM to handle heavier tasks.
Horizontal Scaling: Horizontal scaling involves adding more servers or devices to distribute the workload across them. It's like hiring additional employees in a company to handle increased customer demand - each employee can take care of their share of work, making the overall process faster and more efficient.
