NGINXaaS for Azure now supports HTTP/3 and QUIC.

NGINXaaS can now serve client requests through HTTP/3 connections. NGINX only supports HTTP/3 on the client side and does not support HTTP/3 to upstreams. NGINXaaS utilizes the OpenSSL library; however, the OpenSSL compatibility layer it uses does not support early data.
```
http {
   server {
      # for better compatibility it's recommended
      # to use the same port for http/3 and https
      listen 443 quic reuseport;
      listen 443 ssl;
      ssl_certificate /etc/nginx/foo.pem;
      ssl_certificate_key /etc/nginx/foo.key;
      # ...
   }
}
```
To get started using HTTP/3 and NGINXaaS:
- Update the network security group associated with the NGINXaaS deployment’s subnet to allow inbound traffic for HTTP/3 UDP ports in the NGINX configuration. See our FAQ, for limits on how many unique ports may be specified in a configuration and a list of restricted ports.
- Additionally, add a Managed Identity to your deployment and create SSL/TLS Certificates. For more information on using NGINX with HTTP/3, see the HTTP/3 module.

July 27, 2023

NGINXaaS for Azure now supports higher capacity

NGINXaaS for Azure allowed users to create deployments with a maximum capacity of 80 NCUs under the Standard plan. A recent change now allows users to deploy up to 160 NCUs. Existing NGINXaaS deployments should also scale up to 160 NCUs.

To adjust capacity, refer Adjusting Capacity.

To learn more about capacity restrictions, refer to Capacity Restrictions.

July 13, 2023

NGINXaaS for Azure automatically rotates SSL/TLS certificates

NGINXaaS for Azure now automatically retrieves renewed certificates from Azure Key Vault and applies them to your NGINX deployment. To learn more about this new feature, refer to Certificate Rotation.

July 7, 2023

Improve compatibility with Azure Key Vault certificates generated through merging from an external provider (e.g. keyvault-acmebot)

Key Vault’s certificate merge command puts the server certificate as the last certificate in the generated PFX but NGINX requires that it be the first one in the generated PEM. NGINXaaS will dynamically reorder the certificates to be in chain order with the server certificate first.
Support NGINX log_not_found directive (docs)

June 29, 2023

NGINXaaS can now proxy and load balance UDP traffic.

To configure NGINX to handle UDP traffic, specify the stream directive in your NGINX configuration.
```
stream {
   server {
      listen 53 udp;
      # ...
   }
   # ...
}
```
To learn more about load balancing UDP traffic with NGINX, see TCP and UDP Load Balancing.

NGINXaaS for Azure now supports HTTP/2.

NGINXaaS can now serve client requests through HTTP/2 connections. NGINX only supports HTTP/2 on the client side and does not support HTTP/2 to upstreams.
```
http {
   server {
      listen 443 ssl http2;

      ssl_certificate server.crt;
      ssl_certificate_key server.key;
      # ...

April 7, 2023

NGINX configurations may now listen on ports other than 80 and 443.

NGINXaaS now accepts requests on ports in addition to 80 and 443. Inbound ports are specified in the NGINX configuration using the listen directive.

NGINXaas can be configured to accept requests on up to 5 unique ports.
```
http {
   server {
      listen 8080;
      # ...
   }
}
```
Update the network security group’s inbound security rules associated with the NGINXaaS deployment’s subnet to allow inbound traffic for all listen ports in the NGINX configuration.

See our FAQ, for limits on how many unique ports may be specified in a configuration and a list of restricted ports.

March 16, 2023

Deployment configuration now succeeds after adding a managed identity.

After adding a managed identity to a deployment, the deployment transitions from an Accepted state to a Succeeded state only after the operation to add the managed identity succeeds. The user can then proceed to configure the deployment.

February 21, 2023

Directives auth_jwt_key_file and auth_jwt_require are now supported.

Refer to the auth_jwt_key_file and auth_jwt_require documentation for more information on using these directives.

NGINXaaS is generally available

We are pleased to announce the general availability of NGINX as a Service (NGINXaaS), a first-party-like experience as a service co-developed by Microsoft and NGINX and tightly integrated into the Azure ecosystem.

NGINXaaS, powered by NGINX Plus, is a fully managed service that removes the burden of deploying your own NGINX Plus cluster, installing libraries, upgrading, and managing it.

NGINXaaS simplifies the process of moving your existing NGINX configuration to the Azure cloud. Once your configurations are moved to Azure, securely manage SSL/TLS certificates and keys stored in Azure Key Vault and reference them within your NGINX configurations. You can watch your application’s traffic in real time with Azure monitoring and alerts, and scale your deployment to fit your needs, maximizing cost efficiency. You can create, update, and delete your NGINXaaS deployment via the Azure Resource Manager, the Azure SDK, CLI, and Terraform in addition to the Azure portal.

Our new “Standard” plan is ready for production workloads. If you have a deployment on the “Public Preview” plan, it will continue to work; however, we recommend you recreate it under the “Standard” plan. See Migrating from Public Preview for details.

To learn more, refer to the following NGINXaaS documentation:
