What is Auto-scaling?

Auto-scaling allows you to send additional requests even when you've exhausted your daily usage limit. When you enable this feature, it automatically scales resources to handle more requests, allowing you to continue unhindered.

When should I use Auto-scaling?

Here is a simple user case as an example:

Sarah is a developer who operates a Dapp, and this app often experiences occasional and unexpected surges in traffic. These activity spikes occur especially during specific events or promotional periods. However, the NaaS (Node as a Service) that Sarah is using has a static daily usage limit, which puts her service at risk of disruption during these periods of increased traffic.

To address this issue, Sarah activates the "Auto-scaling" feature on her project. This means that Sarah's Dapp can continue running even with traffic that exceeds the daily usage limit. As a result, it continues to be available to customers and can accommodate the increased load, even if it incurs additional charges. Sarah can maintain the app's performance and reliability while ensuring a seamless service for its users.

How to configure Auto-scaling

Setting an Auto-scaling daily limit

You can set a limit on your Auto-scaling usage to prevent excess usage.

1. Click "Edit" in the "Auto-scaling Daily Limit" section. This will open the Auto-scaling configuration menu.

   

2. Choose the percentage or select the unlimited option in the "Auto-scaling Daily Limit" section. The default value is 200%.

   
   1. If you select '200%,' it means you can use 2X the base daily quota, including the base daily quota itself. This allows you to use an additional 100% on top of the base usage (100%).
      1. For example, if your base daily quota is 2M, choosing Auto-scaling at 200% allows you to use an additional 2M, and if you select 600%, you can use an additional 10M.
   2. You can also select the "Unlimited" option.
      1. This allows you to use the endpoints without any restrictions, even if you exceed your base daily quota. Additional usage may incur charges.
      2. Please note that if you engage in excess usage, we may contact you to prevent excessive charges.

3. Click "Save" to apply changes.
