What technology should Jeff implement to automate the addition of CPU capacity in his web server farm?

1. Puppet

2. Docker

3. Autoscaling

4. Resilient-scaling

The correct answer is: Autoscaling

Autoscaling is the ideal technology for Jeff to implement in order to automate the addition of CPU capacity in his web server farm. This capability dynamically adjusts the number of active servers based on current demand and predefined criteria, such as CPU usage or network traffic. By employing autoscaling, Jeff can ensure that his web server farm efficiently responds to varying loads without manual intervention. This not only helps maintain performance during peak times but also optimizes costs by scaling down resources when demand decreases. The other technologies mentioned have different primary functions. For instance, Puppet is a configuration management tool focused on automating the deployment and management of software and systems across multiple servers, rather than scaling resources based on demand. Docker is primarily a containerization technology that allows for packaging applications and their dependencies in isolated containers, which helps with deployment and consistency but does not inherently manage scaling by itself. Resilient-scaling, though it sounds similar, is not a widely recognized term in the context of cloud resource management and scaling techniques; it may refer to concepts related to maintaining system reliability, but it does not specifically refer to the automated increase of CPU capacity in response to demand. Thus, autoscaling is specifically designed to handle the dynamic allocation of resources like CPU capacity in a web server environment,
