CAM Azure Stack utilizes Microsoft Azure services and resources to provide the ability to move documents and content and sync metadata between multiple Document Management Systems (DMS). CAM Content Mover and Data Sync (Content Sync) use Azure storage blobs as an intermediary place while moving content between the supported Document Management Systems.

To deploy the CAM Azure Stack, you need to deploy the Azure template into your Azure environment. The template deploys a complete solution that contains multiple resources such as function apps, MySQL instances, Blob Storages, and others. These resources are provided and hosted by Microsoft Azure in your Azure account to provide more control over moving content.

Azure & CAM Integration Notes

As of January 30, 2021, Azure is not allowing custom token expiry settings. The conditional access policies determine how the token expires are configured. This requires at least a P1 license in Azure. See the Microsoft link here.

CAM Azure Stack Architecture

Content Mover in CAM uses REST APIs to work with 7 functions, 4 queues, and two triggers to move content.
Data Sync (Content Sync) uses REST APIs to work with 3 functions, 1 queue, and one trigger to sync content.

Prerequisites to the CAM Azure Stack Deployment

Requirements

Administrative access to an Azure subscription where you plan to deploy the CAM Azure stack (http://portal.azure.com )
Administrative access to your organization’s CAM instance.
Your CAM instance Tenant Id, Client Encrypted Key, and CAM Secret Key. You need to contact Litera’s Customer Care team (Support@litera.com) to obtain the Tenant Id before you start the deployment process. Those keys are unique for each CAM instance. If your organization has multiple CAM instances, then you need to request the keys for each instance separately. If you do not have the Tenant Id create a ticket with Litera’s DevOps or Support team before deploying the Azure Client stack. The Encrypted keys and secret key you can obtain in Microsoft.

Deploying and Configuring the CAM Azure Stack

Create a Resource Group

Flexible Server from Single Server Configuration

These steps are used to convert a single server deployment to the flexible server as designated by Azure.

1. Follow the Microsoft tutorial steps. Tutorial: Migrate Azure Database for MySQL - Single Server to Flexible Server online using DMS via the Azure portal - Azure Database Migration Service | Microsoft Learn

Update the server configuration within the CAM config yml file next.

Go to Storage account container.
Find application config container (<instanceUniqueName-topLevelDomain>-application-config eg:tenantname-io-application-config).
Go to yml folder.
Update 3 attributes (host, username, password) with the new flexible server configuration in appconfig yml (appconfig-<environmentStage>.yml) which is in the yml folder.

Note: Single server username format is username@servername eg: abc@mysql-clientname-io

Flexible Server FAQs

Why do I need to create a new resource for flexible server and migrate the data?
Azure Database for MySQL - Single Server is on the retirement path and is scheduled for retirement by September 16, 2024. For more details see this article: https://learn.microsoft.com/en-us/azure/mysql/migrate/whats-happening-to-mysql-single-server
How is the connection established to this sql instance?
CAM Azure functions connect to this SQL instance using the connection string stored in the YML config file.
I can’t find any relevant config in the account?
In the storage account, there should be a bucket with a name ending with “-application-config”, in that bucket, there should be a file with a name that follows the convention “appconfig-<environmentStage>.yml”, that is the file they need to update.

Initialize CAM Azure Stack Configuration

After the deployment is completed successfully, CAM Azure Stack needs to be initialized. The initialization URL is in the template deployment output.

2. Click Outputs, from the template deployment page left panel.

3. The following screen is displayed. Copy the initializeFunctionUrl and paste it into your Internet browser’s URL address bar.

4. The initialization function process URL will respond with the initialization status in JSON format. A successful response looks like the following:

5. Display the bucketname.

6. Display the apiEndPointBaseUrl.

Updating the Client Stack

Prerequisites

Azure CLI: Ensure Azure CLI is installed on your machine. You can download it from Microsoft here:
Administrator Access: Open Powershell with the “Run as administrator“ privilege.
Go to the Github repo: .
Download functionAppsCodeUpdate.ps1
Function App: The function app should already be created in the Client stack otherwise this Powershell script will fail.

Executing the Script

Azure login:

If you haven’t logged in via az login , The script will prompt you to log in through a browser. Please use the Azure account associated with your client stack deployment.
1. If the wrong account is used , you will be prompted to log in again , with up to three attempts allowed.

Resource group Input:

The script will prompt you to enter the resource group name where your stack is deployed.
1. If an incorrect resource group is entered, you will be prompted to re-enter the correct name, with up to three attempts allowed.

Function App Identification:

The script will list all function apps targeted for the JAR upgrade.
It will automatically determine whether to update ETL (Content Mover), ContentSync (Data Sync), or both options, based on the function apps present in your resource group.

Logging:

The script will maintain a log file named CAM_Azure_Stack_log_timestamp.txt to record the latest operations
Older logs will be deleted each time the script runs.

File Management:

The script will download and upload the ZIP file from the same directory where 'functionAppsCodeUpdate.ps1' is located.

Upgrading Jar Files:

After running the functionappsCodeupdate script the jar files will be updated automatically.
