Introduction
In case you are a novice to Azure cloud and wish to study what a logic app is, then undergo my earlier articles.
On this article, we are going to discover the overview of one of many providers, named On-premise Information Gateway, in Azure.
State of affairs
This text will allow you to to know what an on-premise information gateway is, and within the subsequent articles, we are going to undergo the steps that can assist you find out how to set up and configure it with a step-by-step strategy. Let’s gear up.
Stipulations
Primary data of Azure Providers
Background
- If you migrate/redesign/develop your utility to the cloud, then many occasions, it is advisable hook up with the assets which might be current in on-premise servers.
- On-premise information gateway works with the next Azure assets.
- Logic Apps
- Energy BI
- Microsoft Move
- Azure Evaluation Providers
Overview
- The on-premise information gateway service comes beneath the combination providers class in Azure.
- This gateway is nothing however a bridge between on-premise assets and Azure assets.
- If we have to join with on-premise assets; e.g., SQL or FTP information supply, and so on., from Azure Providers like Logic Apps, Energy BI, Microsoft Move, and Azure Evaluation Providers, then on-premise information gateway is among the environment friendly and correct options to make this integration attainable.
- It helps us to speak between two environments securely by encrypting the information and credentials with out modifying the firewall settings.
- This gateway helps solely Logic Apps, Energy BI, Microsoft Move, and Azure Evaluation Providers.
- Transmission of information between these two environments occurs by way of information compression and transport encryption.
The way it works?
- Ship a request from Azure assets to the Azure service bus by way of the connector.
- Connector builds a question with credentials and sends it to Azure Service Bus (totally managed enterprise integration message dealer service).
- Azure service bus retains requests within the queue for processing.
- On-premise information gateway polls and receives the pending requests from Azure service bus.
Word
The gateway creates an outbound connection to the Azure Service Bus. It communicates on outbound ports: TCP 443 (default), 5671, 5672, 9350 by way of 9354. We are able to additionally in a position to power to make use of HTTPs however that results in decreasing the efficiency.
- The gateway decrypts the credentials and connects to the information sources with these credentials and sends a request to execute it.
- On-premise information supply executes the question and the outcomes are despatched again to the gateway
- Lastly, the on-premise information gateway sends the outcomes to the cloud service.
- The beneath picture by Microsoft reveals the detailed information move of the on-premise information gateway
What about troubleshooting?
- On-premise information gateway maintains logs to assist builders
- Gateway service logs: C:UsersPBIEgwServiceAppDataLocalMicrosoftOn-premises information gateway<yyyyymmdd>.<Quantity>.log
- Configuration logs: C:Customers<username>AppDataLocalMicrosoftOn-premises information gatewayGatewayConfigurator.log
- Occasion logs: We are able to get it beneath Software and Providers Logs.
- Open the occasion viewer.
- Increase ‘occasion viewer (native)’
- Go to ‘purposes and providers logs’
- Choose ‘on-premises information gateway service’
Availability and Catastrophe Restoration
- For communication to Azure service from the on-premise information gateway, the gateway needs to be in a working state.
- After we set up the gateway within the on-premise machine then we have to use one key referred to as restoration key.
- By utilizing the restoration key, we are able to restore or transfer the gateway to different machines.
- The restoration key additionally helps emigrate or recuperate the sooner settings of the gateway.
Word
- A single gateway can hook up with a number of information sources.
- It isn’t obligatory to put in this on-premise gateway connector on the machine the place the information supply is current.
- To attenuate latency, you possibly can set up the gateway as shut as attainable to your information supply, or on the identical laptop, assuming that you’ve permissions.
- We are able to set up it anyplace inside your on-premise community, however the vacation spot information supply have to be accessible from a machine the place the gateway is put in.
- Azure Software gateway and on-premise gateway are various things. Don’t be confused.
Abstract
On this half 1, we’ve got realized an summary of the on-premise gateway and its options.
Within the subsequent article, we are going to study to execute the steps to set up and configure it on on-premise machine.
