How to automatically scale nodes horizontally in AccuWeb.Cloud?<\/h2>\n

AccuWeb.Cloud has features that automatically adjust the capacity of your application server, both up and down. This automatic scaling is important for making sure your application runs efficiently. To make this work, you need to set up triggers that control when the system should automatically adjust its capacity. This detailed guide walks you through each step of configuring these triggers, from accessing environment settings to finalizing trigger settings.<\/p>\n

The platform can automatically adjust the number of containers<\/a> in a group based on the amount of work coming in. This happens vertically and horizontally. Vertical scaling means adjusting the capacity of a single container, while horizontal scaling means changing the number of containers in the group.<\/p>\n

\"Container\"<\/a><\/p>\n

When the platform scales horizontally, it evenly distributes the containers across the available hardware to ensure no single part is overloaded. It does this by placing new containers on the hardware with the least work and the lowest load, ensuring reliability.<\/a><\/p>\n

The platform uses tunable triggers, and custom conditions, to decide when to add or remove containers based on the workload. Every minute, the platform looks at the average resource usage over a specified time to determine if it needs to adjust the number of containers.<\/p>\n

\"Nodes\"<\/a><\/p>\n

The statistics gathered include the overall workload of the entire group, considering the usage of each container. For example, if three containers have workloads of 20%, 50%, and 20%, the average is 30%. Notably, the conditions for adding or removing containers are separate and not affected by each other.<\/p>\n

    Set up Triggers for Automatic Scaling<\/h2>\n

    To set up a trigger for automatic horizontal scaling, follow these steps:<\/p>\n

    Note:<\/b> When you add more node servers to an inbuilt application available in Marketplace (not a custom Docker container) without a load balancer, an NGINX balancer is automatically added. If you want a different balancer, you need to set it up manually before adding more servers.<\/div>\n

    Step 1:<\/b> Log in<\/a> to the AccuWeb.Cloud Dashboard and click on the “Settings<\/b>” button for the desired environment.<\/p>\n

    \"Settings\"<\/a><\/p>\n

    Step 2:<\/b> Go to the Monitoring > Auto Horizontal Scaling section in the opened tab. Here, you can see a list of scaling triggers configured for the current environment (if any).<\/p>\n
