Cloud computing is the delivery of various services—including storage, databases, servers, networking, software, and analytics—over the internet (the cloud). This model allows for on-demand access to computing resources, offering flexibility and efficiency that traditional on-premises solutions often cannot match.
Cloud services are typically categorized into three main types:
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
Each of these models serves different business needs and contributes to the overall scalability and performance of cloud computing solutions.
Understanding Scalability in Cloud Computing
Scalability refers to the ability of a system to handle a growing amount of work or its potential to accommodate growth. In the context of cloud computing, scalability can be classified into two types:
Vertical Scalability (Scaling Up): This involves adding more power (CPU, RAM) to an existing machine. For instance, a cloud server can be upgraded with additional resources to manage increased workloads without downtime.
Horizontal Scalability (Scaling Out): This involves adding more machines or instances to distribute the load. Cloud services can easily provision additional servers to handle increased traffic, thereby improving performance.
Benefits of Scalability
