Your organization is launching a promotional campaign for an application that may cause unpredictable surges in user traffic. Which feature should be implemented to ensure uninterrupted availability and consistent performance, adapting to the incoming load without human intervention?
Acquiring fixed capacity physical servers for hosting applications.
Deploying databases across multiple availability zones.
Establishing a dedicated network link to the data center.
Using Auto Scaling to manage virtual server instances.
The correct answer is 'Using Auto Scaling to manage virtual server instances'. This service automatically adjusts the number of instances up or down in response to traffic or utilization changes, promoting uninterrupted availability and consistent performance during demand surges, thereby encapsulating the principles of high availability, elasticity, and agility. The other options are incorrect because they do not address the need for automatic scaling in response to fluctuating demand. Multi-AZ deployments focus on data durability and failover capabilities, not dynamic scaling. Dedicated hosts are for specific use cases, such as software licensing constraints, and do not offer automatic scaling. Lastly, a dedicated network connection improves network performance but does not inherently support scaling or adaptability in traffic variations.
