AWS Service: Amazon EC2 Auto Scaling
Question: How can Amazon EC2 Auto Scaling be used to implement multi-tier application architectures and handle sudden spikes in traffic?
Answer:
Amazon EC2 Auto Scaling can be used to implement multi-tier application architectures by allowing the automatic scaling of resources based on demand for the different tiers of the application. For example, if an application has a web tier and a database tier, EC2 Auto Scaling can be configured to scale up the web tier based on demand, while keeping the database tier fixed. This helps ensure that the web tier can handle sudden spikes in traffic while keeping costs low by not scaling up unnecessary resources in the database tier.
To handle sudden spikes in traffic, EC2 Auto Scaling can be configured to scale up instances based on a variety of scaling triggers, such as CPU utilization, network traffic, or request rates. This helps ensure that the application can handle sudden surges in traffic without experiencing performance issues or downtime.
In addition, EC2 Auto Scaling can be integrated with other AWS services, such as Elastic Load Balancing and Amazon CloudFront, to further optimize application performance and handle sudden spikes in traffic. For example, Elastic Load Balancing can distribute traffic across multiple instances, while CloudFront can cache frequently accessed content to reduce latency and improve response times.
