In this post, I am going to share some quick tips, including Q/A’s and useful links from Azure Job Oriented Day 3 Training of our recently launched new batch of Microsoft Azure Job Oriented, in which we have 25+ hands-on labs in the course.
On our Day 3 Live Session, we covered Azure Networking , VNet Peering
The previous week In Day 2 session we covered about Azure Resource Manager, Subscriptions, NSG, and PowerShell.
Two weeks before In Day 1 session we covered about Azure Cloud Fundamentals, App Services, and Scaling Strategies.
Azure VNet Peering
Azure Virtual Network Peering allows you to connect and share resources securely between two Azure Virtual Networks. It creates a direct, private link across networks, allowing virtual computers, services, and resources to communicate as if they were on the same network. This allows for faster data transfer, increased application scalability, and more efficient resource utilization. VNet peering avoids using the public internet, resulting in low-latency and secure communication. It is especially beneficial for establishing a consistent network environment across numerous Azure regions or subscriptions, as well as for simplifying network design and fostering seamless communication across scattered services.
Q1) Can I peer VNets in different Azure regions?
Ans. Yes, VNets peering can be done in same and different regions both.
Q2) What are the benefits of using VNet peering?
Ans. It offers a lot of benefits.
- Simplified networking: It allows direct communication between Virtual networks.
- Low latency and high bandwidth: It provides communication between peered VNets with low latency and high bandwidth
- Secure communication: It provides secure communication as resource can communicate using private IP.
Q3) Can I peer more than two VNets together?
Ans. Yes, Azure provides this feature which is known as transitive peering, which allows user to peer multiple Vnets together.
Q4) What is VNet vs VNet peering?
Ans. VNet is a logically separate and private network environment inside azure which allow users to deploy and run resources such as virtual machines, containers etc. On the other hand Vnet peering is a concept which allows to communicate two virtual networks together.
Q5) What is the maximum number of VNet peering?
Ans. The maximum number of VNet peering is upto 500.
Q6) What is the difference between virtual WAN and VNet peering in Azure?
Ans. Virtual WAN is a networking service which helps inn simplified and optimizes connectivity for branch offices,remote users and various resources across multiple regions. It is solely designed for managing and connecting networks in a hub and spoke architecture. On the other hand VNet peering is a concept which allows two virtual networks to communicate together.
Q7) What are different types of VNet Peering?
Ans. There are several peering types:
Regional: Regional VNet peering enables communication two virtual networks within the same azure region.
Global : It enables communication between virtual networks across different Azure regions. It enables communication between cross regions securely.
Cross Subscription: It enables communication between VNets in different Subscriptions.
Q8) What is Virtual Machine?
Ans. It is a service in Azure which allows users to run and deploy virtualized instances of computers in the cloud. It operates like a physical computers and can run a variety of OS and applications. It is widely used in website hosting ,application hosting, Database hosting and Bigdata analytics.
Q9) What are the various types of Virtual Machines?
Ans. There are several types of VM:
A series – Entry-level VMs for dev/test : It is used for entry level workloads like development and testing purposes.
Bs-Series – Economical burstable VMs : It is used for the low to moderate CPU utilization.
D-Series – General purpose compute : It is combination of vCPUs, memory and temporary storage which helps in fulfilling production workloads.
E-Series – Optimised for in-memory applications : It is used for memory applications such as SAP HANA.
F-Series – Compute optimised virtual machines : It offers a higher CPU- to memory ratio and are mostly used for batch processing, analytics and gaming.
G-Series – Memory and storage optimised virtual machines : It is used for large SQL and NoSQL databases and data warehousing solutions.
H-Series – High Performance Computing virtual machines : It is used for HPC applications such as financial analysis, weather stimulation.
Ls-Series – Storage optimised virtual machines : It is used for applications which requires low latency, high throughput, and large local disk storage.
M-Series – Memory optimised virtual machines : It is used for memory-intensive tasks like SAP HANA, SAP S/4 HANA, and other large in-memory workloads, offering high-performance parallel processing with up to 4 TB of RAM and 128 vCPUs.
Mv2-Series – Largest memory optimised virtual machines : It is used for memory-intensive tasks like SAP HANA and other large in-memory workloads requiring significant computational power.
N-Series – GPU enabled virtual machines : It is used for compute, deep learning, video editing and graphics workload.
Frequently Asked Questions
Q1) What is VNet Peering?
Ans. It allows you to connect two virtual networks within the same region, enabling resources in those virtual networks to communicate with each other as if they were part of the same network, even though they might belong to separate subscriptions or resource groups.
Q2) What is the difference between VNet and VNet peering?
Ans. A Virtual Network (VNet) is an isolated network environment in cloud computing that allows you to conceptually segregate resources. Its own IP address space, subnet configuration, and network settings are available. Virtual Network Peering, on the other hand, is a feature that allows communication across various VNets inside the same region, allowing resources to connect as if they were in the same network while maintaining each VNet's own identity and configuration.
Q3) How much do virtual network peering links cost?
Ans. There is no charge associated for creating peering connection.
