What is the best way to manage performance drops due to variable traffic on an e-commerce website?

Managing performance drops due to variable traffic on an e-commerce website is crucial for maintaining user experience and sales. Automatic elasticity is the best approach in this scenario because it allows the system to dynamically allocate resources in real-time based on current traffic demands. This means that during peak times, when traffic increases, additional resources (such as processing power or storage) are automatically provisioned to handle the load, ensuring that the website continues to perform optimally without manual intervention.

Automatic elasticity also helps to reduce costs during periods of low traffic, as resources can be scaled down when they are no longer needed. This flexibility is essential for an e-commerce platform that can experience sudden spikes in traffic, such as during promotions or holiday shopping seasons.

By contrast, manual scaling requires human intervention to adjust resources, which can lead to delays and potential performance issues. Network load balancing optimizes traffic distribution across servers but does not necessarily provide additional resources when needed. Resource reservation involves pre-allocating certain resources regardless of current demand, which may lead to underutilization or over-provisioning.

In summary, automatic elasticity provides the agility needed to manage fluctuating traffic loads effectively, ensuring a consistent performance level for users on an e-commerce website.
