2. Azure App Service
A cloud app platform for delivering modern enterprise apps across cloud and mobile devices.
An integrated offering that delivers features and capabilities from a number of existing Azure services
Fully Managed Platform
High Productivity Development
Enterprise Grade Apps

3. Azure Virtual Network(VNet)
TechReady 23
7/22/2018 1:57 PM
Azure Virtual Network(VNet)
Private network in the Azure cloud
Usually uses RFC1918 private IP addresses
Enables network based security and isolation
Control access with Network Security Groups (NSGs)
Can be used with VPNs to create hybrid cloud applications
Customers can control routes for IP traffic to go through those VPNs

4. App Service Environment (ASE)
7/22/2018 1:57 PM
App Service Environment (ASE)
The ASE is a deployment of the Azure App Service into a subnet of a customer’s Azure Virtual Network
The ASE provides:
Network isolation for apps
Larger scale than multi-tenant
More powerful hosts
Ability to work with all VPN types

6. Scaling in an App Service Environment
7/22/2018 1:57 PM
Scaling in an App Service Environment
In an ASE you just scale your App Service Plans, we do the rest
Front Ends
Isolated 1 (Dv2 1)
Isolated 2 (Dv2 2)
Isolated 2 (Dv2 2)
When you scale out your ASPs, the workers are automatically added
Each ASE starts with 2 front-ends. If you make the ASE while making your ASP, the ASP is made with the ASE
After you add 15 total ASP instances, we automatically add another front-end
And if you scale back, we clean up things as appropriate.

7. Scaling out App Service plans (ASPs) in ASE
7/22/2018 1:57 PM
Scaling out App Service plans (ASPs) in ASE
In ASE you can scale to 100 ASP instances
That can be: 1 ASP with 100 instances, ASPs with 1 instance each, or anything in between.

8. Isolated – Pricing plan just for ASE apps
7/22/2018 1:57 PM
Isolated – Pricing plan just for ASE apps
One fee for the ASE plus Isolated App Service plan fees
ASE ownership fee does not change with the size of the ASE and covers all infrastructure including automatically scaled components
ASP fees let you pay for what you use
Prices vary between regions.

ASE high level network
If you want private site access then create an ASE that uses an Internal Load Balancer instead of one with an external VIP
If the VNet is connected to an on premises network via a Site to Site or ExpressRoute VPN then they can access resources on premises
Because the apps are in the ASE inside the customer’s VNet, they can access resources that are also in the VNet
The apps in an ASE are exposed to the internet through a VIP

12. App Service Environment endpoints
TechReady 23
7/22/2018 1:57 PM
App Service Environment endpoints
Internet accessible endpoint:
All app inbound and outbound traffic flow through a public VIP
App hostnames are in public DNS
App names have the form <appname>.<ASEname>.p.azurewebsites.net
Certificates are created with your ASE
Type of ASE commonly called the external ASE or public ASE
Azure virtual network address endpoint:
All app inbound flows in to an address in the subnet used by the ASE
App outbound to the internet goes though a public VIP
App hostnames need to be managed in a customer DNS
User defines domain for the ASE that apps are made in
Certificates need to be provided by the customer
Type of ASE commonly called the ILB ASE as it uses an Internal Load Balancer

23. Routes and security groups
Azure virtual network routes are applied on traffic leaving a resource in a subnet.
Route selection is based on longest prefix match.
If more than one route with the same prefix match then route is based on origin.
User defined routes, aka route tables
BGP route (with ExpressRoute)
System route
Network security groups:
Used to restrict access to/from IP’s and ports. Does not work with hostnames
For ASE
Must allow inbound to ASE subnet on ports 454/455
Must allow outbound from ASE subnet to any IP.
Must allow ASE subnet to talk to ASE subnet on any port

24. Forced tunnel and ASE TechReady 23 7/22/2018 1:57 PM
To work with forced tunnel configurations: - incoming management traffic has to go back the way it came - the firewall for the ASE dependencies needs your egress addresses

25. Supporting forced tunnel configuration
7/22/2018 1:57 PM
Supporting forced tunnel configuration
To enable forced tunnel config on an existing ASE:
Create/edit the ASE subnet route table to include App Service management addresses for inbound traffic
Add your gateway/NAT addresses to the ASE firewall list
To create an ASE in a force tunneled VNet:
Create the ASE with a template and set your gateway/NAT addresses for the ASE firewall
