HI..
What different between pay as you go and reserve instance / capacity?
How we can know if our VM using pay as you go or reserve instance?
Hi @Handian Sudianto ,
As explained by @vipullag-MSFT reservations reduce cost of resources only and you will be charged by using the same credit card and subscription.
You can check if your VM is using Reservation from Reservation dashboard:
Hi @rafalzak
If there are no items in reservation dashboard, this mean all my resource using pay as you go? It's possible to change some of VM from pay as you go to reservations?
Yes, it means you don't have any reservations.
Reserved VM Instances (RIs) provide a significant discount over pay-as-you-go VM prices by allowing you to pre-purchase the base costs of your VM usage for a period of 1 or 3 years. Reserved instance discount will automatically apply to matching VMs, you don't need to re-deploy resources to get reservation discount. The reservation applies only to hardware usage. Windows is charged separately
On the screen above there is Purchase Now button which also provide some additional info.
Hi @rafalzak
So it's possible if existing VM migrated from pay you go to reserved or should we make a new VM purchase?
You can Reserve existing vm you don't need to redeploy them.
Welcome to Microsoft Q&A Platform, thanks for posting your query here.
If you purchase Azure Cloud Services are pay-as-you-go pricing then you will get few services for free and you will be billed monthly, for the services that you have utilized beyond free amount. In this model there is no upfront commitment and you can cancel anytime.
However, Azure Reserved Virtual Machine Instances, significantly reduce costs—up to 72 percent1 compared to pay-as-you-go pricing—with one-year or three-year terms for Windows and Linux virtual machines (VMs).
Purchase Azure Reserved VM Instances for one-year or three-year terms directly in the Azure portal with a single, upfront payment or monthly billing.
Refer this document for faqs on reserved instances.
Hope this helps.

Is the RI discount on an unlimited number of hours or the term of commitment or is there a cap on the hours?
