Scaling in AWS refers to the ability to adjust the capacity of resources to accommodate changes in demand. It allows organizations to meet varying workloads and ensure optimal performance, cost-efficiency, and availability. AWS offers different scaling options to address specific needs. Let's explore the concept of scaling in AWS and discuss these options:
1. Vertical Scaling:
Vertical scaling, also known as scaling up or instance resizing, involves increasing or decreasing the capacity of an individual resource, such as an EC2 instance or a database instance. In this approach, you upgrade to a higher instance type with more compute, memory, or storage capacity to handle increased demand or downgrade to a lower instance type during periods of low utilization. Vertical scaling is suitable when the workload can be handled by a single instance and requires quick adjustments.
2. Horizontal Scaling:
Horizontal scaling, also known as scaling out, involves adding or removing multiple instances to handle changes in workload. Instead of upgrading the capacity of a single instance, you distribute the workload across multiple instances, leveraging the concept of elasticity. This approach allows for better fault tolerance, improved performance, and the ability to handle higher traffic volumes. Horizontal scaling is typically....
