Introduction
Cloud computing and Azure can help businesses improve their efficiency by automating many tasks and processes. This allows businesses to focus on their core competencies and frees up time and resources that would have been spent managing IT infrastructure. Additionally, with cloud computing, businesses no longer need to worry about software updates and maintenance as these tasks are handled by the cloud service provider.
Creating a Server on Azure
1. Choosing the right Azure plan: Before creating a server on Azure, it is important to choose the right Azure plan that meets your business needs and budget. Azure offers a variety of plans, such as Pay-As-You-Go, Enterprise Agreement, and Free Trials. Evaluate your business requirements and select a plan that offers the necessary services and features, and fits your budget.
2. Creating a virtual machine: Once you have selected an Azure plan, you can proceed with creating a virtual machine (VM). A VM is a compute resource that can be provisioned and accessed over the internet. To create a VM, follow these steps:
Log into the Azure portal and click on the “Create a resource” button.
Search for “Virtual machine” and select it from the list of services.
Choose your desired operating system, virtual machine size, and other configurations.
Select the appropriate location, resource group, and availability options for your VM.
Specify a name for your VM and click on the “Create” button.
3. Configuring the virtual machine: Once the VM is created, you can configure it according to your requirements. Some basic configurations include:
Connecting to the VM: You can connect to the VM using remote desktop protocol (RDP) for Windows VMs or secure shell (SSH) for Linux VMs.
Setting up storage: You can attach disks to the VM to store your data. Azure also offers managed disks or storage accounts for better management and scalability.
Configuring networking: Configure network security groups to control traffic to your VM, set up virtual networks for isolated access, and assign a static or dynamic IP address.
4. Setting up security and access controls: Securing your virtual machine is crucial to protect your data and applications. Some best practices include:
Configuring firewalls: Set up Network Security Groups (NSGs) to allow or block specific types of traffic to your VM.
Enabling encryption: Use Azure Disk Encryption to encrypt the data on your VM’s disks.
Implementing backups: Set up backups for your VM to ensure data protection and easy recovery in case of any failures.
Managing access: Use role-based access control (RBAC) to control who can access and manage your VM. — Monitoring: Use Azure’s monitoring and logging tools to track and detect any potential threats or issues.
Configuring Queue Manager on Azure
Creating a Queue:
Log in to the Azure portal and select your subscription.
Click on the “Create a resource” button and search for “Storage Queue” in the search bar.
Select “Storage Queue” from the results and click on “Create” to start the creation process.
On the “Basics” tab, enter a name for your queue and select the storage account where you want the queue to reside.
Choose a location for the storage account and select the pricing tier based on your needs.
Click on the “Review + create” button and then on “Create” to create the queue.
Once the deployment is complete, you can access your queue from the storage account associated with it.
Configuring Queue Properties:
Select the queue you created and click on the “Properties” tab.
Here, you can configure various properties such as the default queue retention period, metadata, and access policy.
You can also enable dead-lettering for the queue, which moves expired or undeliverable messages to a separate queue for further analysis.
Setting up Queue Security:
To secure your queue, you can configure Shared Access Signatures (SAS) on the “Shared access signature” tab.
Generate a SAS token with specific permissions and duration for individuals or applications to access the queue.
You can also set up access policies and define allowed IP addresses for additional security.
Monitoring and Managing the Queue:
From the “Metrics” tab, you can monitor critical metrics such as the number of messages in the queue, the size of the queue, and the number of incoming and outgoing messages.
You can also set up alerts for certain metrics to receive notifications when specific thresholds are met.
The “Monitoring” tab provides a detailed view of the queue’s activity, including enqueue and dequeue operations, messages processed, and average latency.
You can also manage your queue from the “Queue service” tab, where you can add or delete messages, update queue properties, and view the queue’s access policy.
Configuring DNS on Azure
Registering a domain name on Azure:
Sign in to the Azure portal (https://portal.azure.com/) using your credentials.
In the Azure portal, click on the “Create a resource” button on the top left corner.
In the search bar, type “domain” and select “Azure DNS” from the search results.
Click on the “Create” button on the Azure DNS page.
Enter the domain name you want to register and click on the “Check availability” button.
If the domain name is available, click on “Create” and follow the instructions to complete the registration process.
Once the domain is registered, you can manage it from the Azure DNS page in the Azure portal.
Creating DNS records on Azure:
In the Azure portal, click on the “Create a resource” button on the top left corner.
In the search bar, type “DNS zone” and select “DNS zone” from the search results.
Click on the “Create” button on the DNS zone page.
Enter the domain name for which you want to create DNS records.
Under “Resource group”, select an existing resource group or create a new one.
Under “Pricing tier”, select the pricing tier based on your requirements.
Click on the “Create” button.
Once the DNS zone is created, click on it to open the DNS zone page.
Click on the “Add record set” button.
Enter the name and type of the record you want to create.
Configure the record settings and click on the “Add record set” button.
Repeat steps 9–11 to create additional DNS records.
Configuring DNS security on Azure:
In the Azure portal, go to the DNS zone page.
Click on the “Configuration” tab.
Under “Advanced settings”, click on “Threat intelligence”.
Enable the “Threat intelligence” toggle button.
Select the severity level for threat alerts.
Under “Network rules”, enable the “Network rules” toggle button.
Choose the action to take against malicious requests.
Click on the “Save” button to apply the changes.
Managing DNS settings on Azure:
In the Azure portal, go to the DNS zone page.
Click on the “Configuration” tab.
From here, you can manage settings such as the SOA record, NS records, and DNSSEC.
To manage record sets, click on the “Record sets” tab.
From here, you can add, edit, or delete record sets.
To manage DNS zone delegation, click on the “Delegation” tab.
From here, you can manage name server delegation for the DNS zone.
To manage DNS notifications, click on the “Notifications” tab.
From here, you can set up notifications for changes made to the DNS zone.
Click on the “Save” button to apply any changes made to the DNS settings.
