Scaling up Azure website instance
Scaling up Azure website instance is an important aspect of managing scale for a website and how it has to do with the resources per instance the website requires. For example, a website may initially only require the 1 core and 1.75 GB of memory to run as designed. However, over time and as more features are added, the website may require more resources, such as 2 cores and 3.5 GB of memory. Azure Websites provide a way for you to scale up the instance size of your running instances. There are three settings available for the instance size, as shown here:
- Small (1 core, 1.75 GB memory)
- Medium (2 cores, 3.5 GB memory)
- Large (4 cores, 7 GB memory)
The instance size setting is only available for websites running in a Basic and Standard mode hosting plan. This setting is not applicable for websites running the Free or Shared plans. It is not possible to autoscale the instance size for running instances of your website. If you define your instance size as Medium, all of your running instances will be Medium. In other words, you cannot have one instance of your website running a Small instance size and another instance of the same website running a Large instance.
