Elastic Load Balancing
This service can be deeply integrated with Elastic Load Balancing by automatically handling the registration and de-registration of Docker containers.
What is Elastic Container Service?
To trigger an alarm, this type of comparison (like >, >=, <, <=) must be used.
What is a static threshold condition
This setting ensures your Auto Scaling group never falls below a specified number of instances.
What is minimum size?
This Elastic Load Balancing configuration helps developers route traffic between on-premises resources and AWS targets by either using the same load balancer or using DNS-based weighted routing over separate load balancers.
What is hybrid load balancing?
You’d set an alarm if average CPU utilization on EC2 is greater than this percentage for 5 minutes.
What is 60%
Scaling to meet peak demand all year causes 76% of this resource type to remain idle during low-traffic periods.
What is provisioned capacity?
By registering Lambda functions as targets via Application Load Balancing, developers can serve requests from any HTTPS client (including web browsers), enabling access to these types of applications.
What are serverless applications?
This is the state an alarm enters when a threshold condition is met.
What is the ALARM state
These actions allow you to scale your EC2 instances at specific times, like every Monday morning.
What are scheduled scaling actions?
You manage a load balancer that routes traffic across several EC2 instances over multiple AZs. Suddenly, one instance starts failing some of its requests. What Elastic Load Balancing feature should be used to automatically prevent traffic from reaching this faulty instance (until further notice)?
What are health checks?
This advanced configuration allows you to monitor a composite condition that depends on multiple metrics, using logical expressions such as AND, OR, and NOT. It enables you to focus on specific operational states, such as only triggering if CPU Utilization exceeds 80% and available memory drops below 200 MB and the number of healthy instances is less than 3.
What is a composite alarm
You manage a service that experiences both predictable traffic spikes and sudden demand surges. To stay cost-efficient and responsive, you want to scale in advance of expected load while also reacting to real-time changes.
What is predictive scaling?
