Azure Insights: Front Door Service; IOPS performance; RSS feeds with Logic Apps; Azure Pipelines agent; Gen 2 VMs

This week, Azure pros share their insights on working with Azure Front Door Service, addressing IOPS performance issues, using Azure Pipeline agents and more.

Working with Azure Front Door Service

Vincent-Philippe Lauzon blogged about the implications of Azure Front Door Service for users. It combines a variety of capabilities, such as Web Application Firewall, accelerated global routing, global load balancing, aspects of CDN and reverse proxy—which does URL-based routing and SSL termination. He noted that it's priced on a consumption basis per outbound data transfer.

Azure Front Door is meant to route public traffic to public endpoints. It doesn’t integrate with Azure Virtual Networks.

He showed how to use an ARM template with four parameters to deploy, drawing inspiration from Azure Quickstart Templates. Lauzon also gave examples of CIDR to configure Web Application Firewall. The system will "discriminate" against other traffic, such as that from a browser relative to traffic coming from another Front Door Service instance. He also offered insights on testing the implementation and switching from HTTP to HTTPS.

IOPS performance issues

Cor den Boer, writing on 2 Azure commented on the issue of slow input-output operations per second (IOPS) with Azure VMs. He recommended checking on the type of VM in use, for starters, and whenever possible switching from HDD to SSD.

But keep in mind, not all virtual machines do support Premium SSD Storage, with an effective limit of 500 IOPS per disk, like in the Av2 series. And then there is host caching, that effects performance as well.

For extremely demanding workloads, users can also turn to Lsv2-series storage optimized VMs with up to 3.8 million IOPS on NVMe disks. According to Boer, Av2, Dv2, Dv3, Ev3, NC, NV and G-series VMs don't offer Premium SSD storage. Using managed disks also provides advantages over unmanaged disks—which are limited to 20,000 IOPS. Microsoft is currently previewing Ultra SSDs, which charge for extra reserved IOPS capacity, with adjustable disk performance and maximum throughput of 2000 Mbps.
