Azure's free tier does not offer an "always free" option for virtual machines (VMs) in the same way that some other cloud providers do. Instead, Azure provides a limited-time free tier for certain services, including VMs. For the first year, you can use 750 hours of B1S VMs per month for both Windows and Linux. This means you can run two VMs continuously for a month without incurring additional costs, provided you stay within the free tier limits.
The B1S VM size is a small instance suitable for development and testing environments. It typically includes 1 vCPU and 1 GB of RAM. This size is part of the Azure Standard tier, which offers better compute, memory, and IOPS compared to the Basic tier. However, the Basic tier is not recommended for new deployments as it lacks features like Load Balancer support and auto-scaling.
If you need larger VM sizes, you would need to upgrade beyond the free tier, which would incur standard rates for usage beyond the free limits. Azure does not provide larger VM sizes within its free tier offerings.
Para obter informações detalhadas sobre os tamanhos da VM do Azure e suas especificações, você pode usar a ferramenta Seletor de Máquina Virtual do Azure para encontrar o melhor ajuste para sua carga de trabalho. Additionally, Azure offers a cost calculator to help estimate costs for specific configurations beyond the free tier.
