Deployment slots are a way for Azure customers to create multiple instances of their applications in the same region so that they can scale up or down as needed. Azure offers three types of deployment slots: standard, premium, and premium-plus.
Standard deployment slots are the most basic type, and they allow you to create one instance of your application per deployment slot. Premium deployment slots allow you to create up to 10 instances of your application per deployment slot, and premium-plus deployment slots allow you to create up to 50 instances of your application per deployment slot.
Azure offers different pricing options for each type of deployment slot. For standard deployment slots, the price is based on how many instances you want to create.
Premium deployment slots have a flat price, regardless of how many instances you want to create. Premium-plus deployment slots have a price based on how much memory you want to use per instance. .
The good news is that you don’t need a specific type of Azure subscription to use deployment slots. You can use standard or premium-plus slots in any subscription level that includes Azure compute resources.
Deployment slots are a great way for customers who need to scale up or down their applications frequently to do so without having to redeploy their applications every time they make a change. The downside is that they’re not available in all regions, and they don’t work with all types of applications.
If you’re looking for a way to scale your applications quickly and easily, then deployment slots might be the solution for you.
