Table of contents

👦: Prefaces by Cenz

When I was revising for the AZ-104 Azure Administrator Exam, I generated this table. My mind was wandering to a more efficient way to learn. I didn't cross-check the Bing Chat response carefully, so there might be a mistake. Take this post as a reference for the prompt and response.

👦: Impression by Cenz

First of all, I'm impressed with the comparison table on day one. Bing added the fact from the search result to the GPT model. It lists out most of the features and compares them. However, the next day, when I use the same prompt, I get a different answer. The response isn't satisfactory. It's just one sentence about the Azure service definition in the table. In short, I think it helps with the revision. The AI's "emotion" can make a big difference, but I am not sure how to comfort it.

Azure Comparison Result

The following tables are exclusively generated by Bing Chat. The content wasn't changed, just the formatting.

🤖: I would like to know to difference between this two services. Can you list them in a table?

Sure, I can list some of the differences between Virtual Firewall and NSG in Azure in a table. Here is a summary based on the search results:

🤖: What is the difference between Azure VPN Gateway and Virtual network gateway. List them in a table.

A VPN gateway is a specific type of virtual network gateway that is used to send traffic between an Azure virtual network and an on-premises location over the public internet. You can also use a VPN gateway to send traffic between Azure virtual networks ². When you create a virtual network gateway resource in Azure, you can select the VPN or ExpressRoute gateway type in Azure ¹.

Here is a table that summarizes the differences between Azure VPN Gateway and Virtual Network Gateway:

🤖: What is the difference between, policy-based VPN gateway, route-based VPN gateway and path-based VPN gateway. List them in table.

A policy-based VPN gateway uses the combinations of prefixes from both networks to define how traffic is encrypted/decrypted through IPsec tunnels. It is typically built on firewall devices that perform packet filtering. IPsec tunnel encryption and decryption are added to the packet filtering and processing engine ¹.

A route-based VPN gateway uses routes that are added to a virtual private gateway to direct traffic to the IPsec tunnel. These routes can be configured statically or dynamically using routing protocols ¹.

I couldn't find any information about a path-based VPN gateway. It's possible that you may have mistaken the term. Could you please clarify if you meant something else?

In Azure Firewall, there are three types of rule collections: NAT, Network, and Application. Rule Collection Groups contain zero or more Rule Collections. You can define multiple Rule Collection types within a single Rule Group. You can define zero or more Rules in a Rule Collection. Rules in a Rule Collection must be of the same type (NAT, Network, or Application)¹.

Here is a table that summarizes the differences between the three types of rule collections:

🤖: Compare Azure ExpressRoute and Azure Virtual WAN. List them in a table.

Azure ExpressRoute is a service that lets you extend your on-premises networks into the Microsoft cloud over a private connection with the help of a connectivity provider. With ExpressRoute, you can establish connections to Microsoft cloud services, such as Microsoft Azure and Microsoft 365⁴.

Azure Virtual WAN is a networking service that brings many networking, security, and routing functionalities together to provide a single operational interface. Some of the main features include branch connectivity (via connectivity automation from Virtual WAN Partner devices such as SD-WAN or VPN CPE) and site-to-site VPN connectivity⁷.

Here is a table comparing the two services:

🤖: What is the difference between vNet and Subnet in Azure? List them in a table.

sl.bing.net/kz7opmZ2WE8

A virtual network (vNet) is a logically isolated section of the Azure cloud where you can launch Azure resources in a virtual network that you define. A subnet, on the other hand, is a range of IP addresses within a virtual network. You can divide a virtual network into multiple subnets.

Here is a table that summarizes the differences between a vNet and a Subnet in Azure:

🤖: What’s the difference between Kubenet and Azure CNI. list them in a table.

Kubenet and Azure CNI are two different network plugins used by Azure Kubernetes Service (AKS) for networking. With Azure CNI, nodes get IP addresses from the subnet of the pre-defined VNET¹. With Kubenet, nodes get IP addresses from the subnet of the VNET that resides in the system resource group (‘MC_’-group). Azure creates this VNET and subnet automatically¹.

For production deployments, both Kubenet and Azure CNI are valid options³. However, there are advantages and disadvantages to each. At a high level, Kubenet conserves IP addresses while Azure CNI provides better performance⁴.

Here's a table summarizing their differences:

FeatureKubenetAzure CNI

Tell me the different between Azure connect sync and Azure connect cloud. Show me in a table.

Azure AD Connect sync and Azure AD Connect cloud sync are both used to synchronize users, groups, and contacts to Azure AD. However, there are some differences between the two.

With Azure AD Connect sync, provisioning runs on the on-premises sync server and configuration is stored on the on-premises sync server¹.

With Azure AD Connect cloud sync, the provisioning configuration is stored in the cloud and runs in the cloud as part of the Azure AD provisioning service¹.

Here is a table that compares some of the features of Azure AD Connect sync and Azure AD Connect cloud sync:

FeatureAzure AD Connect syncAzure AD Connect cloud sync
Connect to single on-premises AD forest
Connect to multiple on-premises AD forests
Connect to multiple disconnected on-premises AD forests

Difference table in Event Grid, Service Bus, Event Hubs, and Storage queues

Sure! Here is a table that compares some of the key differences between Event Grid, Service Bus, Event Hubs, and Storage queues:

ServiceDescription
Event GridAn eventing backplane that enables event-driven, reactive programming. It uses the publish-subscribe model. Publishers emit events, but have no expectation about how the events are handled. Subscribers decide on which events they want to handle. Event Grid is deeply integrated with Azure services and can be integrated with third-party services. It simplifies event consumption and lowers costs by eliminating the need for constant polling¹.
Service BusPart of a broader Azure messaging infrastructure that supports queuing, publish/subscribe, and more advanced integration patterns. It's designed to integrate applications or application components that may span multiple communication protocols, data contracts, trust domains, or network environments².
Event HubsA big data streaming platform and event ingestion service. It can receive and process millions of events per second. Data sent to an event hub can be transformed and stored by using any real-time analytics provider or batching/storage adapters¹.
Storage queuesPart of the Azure Storage infrastructure. They allow you to store large numbers of messages. You access messages from anywhere in the world via authenticated calls using HTTP or HTTPS. A queue message can be up to 64 KB in size. A queue may contain millions of messages, up to the total capacity limit of a storage account. Queues are commonly used to create a backlog of work to process asynchronously².

I hope this helps! Is there anything else you would like to know?
