Today customers rely on Azure’s application, infrastructure, and network monitoring capabilities to ensure their critical workloads are always up and running. It’s exciting to see the growth of these services and that customers are using multiple monitoring services to get visibility into issues and resolve them faster. To make it even easier to adopt Azure monitoring services, today we are announcing a new consistent purchasing experience across the monitoring services. Three key attributes of this new pricing model are:

1. Consistent pay-as-you-go pricing

We are adopting a simple “pay-as-you-go” model across the complete portfolio of monitoring services. You have full control and transparency, so you pay for only what you use.

2. Consistent per gigabyte (GB) metering for data ingestion

We are changing the pricing model for data ingestion from “per node” to “per GB”. Customers told us that the value in monitoring came from the amount of data received and the insight built on top of that, rather than the number of nodes. In addition, this new model works best for the future of containers and microservices where the definition of a node is less clear. “Per GB” data ingestion is the new basis for pricing across application, infrastructure, and networking monitoring.

3. Choice of pricing models for existing customers

We understand that some of our existing customers have use cases that are optimized for the current “per node” model and we want to ensure that this change does not disrupt you. Existing customers can choose to continue with the current per node pricing model. If you are an existing customer of an Operations Management Suite license, you can continue with the current model or adopt the new model at renewal if you wish.

The new pricing model is available today to all customers. Many of these changes are a direct result of collaboration between Microsoft and the community. Thank you for the ongoing feedback as we partner together to build monitoring in Azure that spans infrastructure, applications, and networks.

Learn more about the new pricing model by visiting the updated pricing calculator or the individual product pricing pages for Log Analytics, Network Watcher, Azure Monitor, and Application Insights.

For guidance on managing data ingestion visit the documentation pages for Log Analytics and Application Insights. The pricing for all other services in the Azure security and management portfolio including Azure Backup, Azure Security Center, and Azure Site Recovery remains the same.
