AWS, JavaScript, React - Deploy Web Apps on the Cloud - Introduction to Scaling

The video tutorial explores scaling in cloud computing, focusing on vertical and horizontal scaling. Vertical scaling involves upgrading a single instance's hardware, while horizontal scaling adds nodes to distribute load. The tutorial explains the role of load balancers in managing traffic and ensuring efficient resource utilization. It concludes with a preview of a hands-on demonstration in the next lecture.

What is the primary focus of vertical scaling in cloud computing?

• Implementing automated health checks

• Distributing load among multiple nodes

• Upgrading the hardware of a single instance

• Adding more instances to a network

In the context of cloud computing, what is a node?

• A single instance with upgraded hardware

• A type of load balancer

• A connection point in a network that can handle data

• A tool for monitoring application performance

How does a load balancer determine the health status of a node?

• Through routine automated health checks

• By monitoring the number of incoming requests

• By checking the node's memory usage

• By evaluating the node's storage capacity

What is the role of a front-end load balancer in horizontal scaling?

• To monitor the CPU usage of nodes

• To distribute requests among healthy nodes

• To add more nodes to the network

• To upgrade the hardware of nodes

What service can be used to deploy Application Load Balancers (ALBs) within a node?

• Health Check service

• Node Balancer service

• Instance Cluster service

• Vertical Scaling service
