What is D series in Azure?
The D-series Azure VMs offer a combination of vCPUs, memory and temporary storage able to meet the requirements associated with most production workloads. The D v3 virtual machines are hyper-threaded general-purpose VMs based on the 2.3 GHz Intel® XEON ® E5-2673 v4 (Broadwell) processor.
What are B series VMs in Azure?
The B-series provides you with the ability to purchase a VM size with baseline performance that can build up credits when it is using less than its baseline. When the VM has accumulated credits, the VM can burst above the baseline using up to 100% of the vCPU when your application requires higher CPU performance.
What are the different types of VM in Azure?
Azure Virtual Machine Types
- General purpose VMs.
- Compute optimized VMs.
- Memory optimized VMs.
- Storage optimized VMs.
- VMs for Graphics Processing (GPUs)
- High performance compute.
What is G Series VM in Azure?
G-Series. Memory and storage optimized VMs. This is a solution for workloads with high memory and storage requirements. G-series VMs are among the Microsoft Azure instance types that feature the most memory, the highest processing performance, and the biggest SSD storage capacity.
What is a burstable VM?
A burstable instance is a virtual machine (VM) instance that provides a baseline level of CPU performance with the ability to burst to a higher level to support occasional spikes in usage.
What is vCPUs?
A virtual CPU (vCPU) also known as a virtual processor, is a physical central processing unit (CPU) that is assigned to a virtual machine (VM). By default, virtual machines are allocated one vCPU each.
What is scale up and scale out in Azure?
“Scale up” means upgrade the capacity of the host where the app is hosted. Ex: Increase the memory from 1.75GB to 3.5GB. “Scale out” means upgrade the capacity of the app by increasing the number of host instances.
What is scale out in Azure?
Scale-Out (Horizontal scaling) It is basically adding multiple instances of the application that runs in your app. In other words, it increases the number of VM instances up to 30 depending upon your pricing tier.
What VM Series should you consider?
Answer. The VM series that you should consider if you want to host applications that require high-performance for persisted data is VMware Workstation, Oracle VM Virtual Box or Microsoft Azure Compute. These devices have the highest flexibility of workload hosting.
What are virtual network gateways used for?
Virtual Network Gateway: Virtual Network Gateway sits on the boundary of a VNet’s subnet and enables connectivity between that subnet and other networks or VPNs. This is where most of the VPN configuration resides.
What is B series VM?
Background. The B-series (burstable) VMs are ideal for workloads that do not need the full performance of the CPU continuously, for example, web servers, small databases and development, and test environments. These workloads typically have performance requirements which come in bursts.
