Scalability and elasticity are two distinct concepts in cloud computing that help organizations achieve flexibility and efficiency in their IT infrastructure. Scalability refers to the ability of a system to adjust resources to meet changing demands, typically through planned and manual processes such as vertical or horizontal scaling. Elasticity, on the other hand, is an auto-scaling feature that ensures resources are always available when needed and automatically released when demand decreases. While scalability and elasticity are often used interchangeably, they refer to different concepts in cloud computing, with scalability focusing on long-term adjustments and elasticity focusing on short-term dynamic adjustments. Organizations can achieve both scalability and elasticity through various means such as using cloud providers' built-in features, load balancers, containerization, monitoring, and automation. The future of scalability and elasticity is heading towards serverless resource provisioning, which offers cost-effective and agile solutions for startups and enterprises alike.
