1Apps and storage quotas are per App Service plan unless noted otherwise.
2The actual number of apps that you can host on these machines depends on the activity of the apps, the size of the machine instances, and the corresponding resource utilization.
3Dedicated instances can be of different sizes. See App Service Pricing for more details.
4Premium tier allows up to 50 computes instances (subject to availability) and 500 GB of disk space when using App Service Environments, and 20 compute instances and 250 GB storage otherwise.
5The storage limit is the total content size across all apps in the
same App Service plan. More storage options are available in App Service Environment
6These resources are constrained by physical resources on the dedicated instances (the instance size and the number of instances).
7If you scale an app in the Basic tier to two instances, you have 350 concurrent connections for each of the two instances.
8Premium tier allows backup intervals down up to every 5 minutes when using App Service Environments, and 50 times per day otherwise.
9Run custom executables and/or scripts on demand, on a schedule, or continuously as a background task within your App Service instance. Always On is required for continuous WebJobs execution. Azure Scheduler Free or Standard is required for scheduled WebJobs. There is no predefined limit on the number of WebJobs that can run in an App Service instance, but there are practical limits that depend on what the application code is trying to do.
10SLA of 99.95% provided for deployments that use multiple instances with Azure Traffic Manager configured for failover.
