It's like a workout for your mind! Not to mention, it can even improve your memory and slow down cognitive decline as you age.

Moreover, books are fantastic for expanding your vocabulary and improving your language skills. Imagine being able to articulate your thoughts more clearly and effectively, whether you're writing a blog post or presenting a new idea at work. That's the power of reading.

Now, let's talk about stress. We all know how overwhelming life can get, especially in the fast-paced world of technology. Here's where books come to the rescue. Immersing yourself in a good book can be a wonderful way to relax and de-stress. It provides a mental escape, calming your mind and reducing anxiety.

Have you ever found it challenging to focus or stay disciplined? Reading can help with that too. It requires patience and concentration, qualities that are often undermined by our instant gratification culture. Developing a reading habit can enhance your ability to focus and build discipline – both incredibly valuable traits in personal and professional life.

But that's not all. Reading fiction, in particular, can improve your empathy and emotional intelligence. By experiencing the lives and emotions of characters, you gain a better understanding of human nature and social relationships. This can enhance your interpersonal skills and make you a more empathetic person.

Why Do Influencers Encourage Reading?

     • Name: Enter a name for your private view.
     • Compartment: Select the appropriate compartment.
   • Click "Create View".

Associating the Private View with a VCN

Once the private view is created, the next step is to associate it with your VCN. This association ensures that DNS queries from resources within the VCN use the DNS configuration specified in the private view.

Steps to Associate the View with a VCN

1. Navigate to the VCN
   • In the OCI console, go to the "Networking" section and select "Virtual Cloud Networks".
2. Select the Target VCN
   • Choose the VCN you want to associate with the private view.
3. Associate the View
   • In the VCN details page, find the "DNS Resolver" section and click on "Associate View".
   • Select the private view you created in the previous step.
   • Click "Associate".

Add A record for the OCI instance IP which is created in the VCN, and we will test whether it will resolve the hostname based on the record.

Testing the DNS Configuration

After associating the private view with your VCN, it's essential to test the DNS configuration to ensure it's working as expected.

Steps to Test DNS

1. Launch an Instance in the VCN
   • Go to the "Compute" section and create a new instance or use an existing instance within the VCN associated with the private view.
2. Connect to the Instance
   • SSH into the instance using your preferred method.
3. Perform DNS Queries
   • Use the nslookup or dig command to test DNS resolution.
   • For example, to test the resolution of a domain in your private zone:

     nslookup cmsapp.cms.com

   • Verify that the DNS queries return the expected results.

Conclusion

In this blog, we walked through the steps to create a private view in OCI DNS, associate it with a VCN, and test the DNS configuration. These steps are crucial for managing internal DNS resolution within your OCI environment.

If you have any questions or run into any issues, feel free to reach out.

All about DNS - OCI DNS - Part 1

What is DNS:

People use their names to communicate with each other. Humans use website names to access them over the internet. Likewise, computers use IP addresses to communicate with each other on private on-premises networks or on the internet.

Humans don’t like or remember IP addresses, so they type only website addresses. Here comes the role of DNS. DNS converts the names to the IP addresses.

Create Private Zone:

In Oracle Cloud Infrastructure (OCI), a Private Zone is a crucial component of the DNS (Domain Name System) service that enables you to manage and resolve domain names within your private network environment. Here's a breakdown of what a Private Zone entails:

Isolation and Control:

Private Zones offer a secure and isolated environment for managing domain names within your OCI tenancy. They allow you to control DNS resolution for your private network resources without exposing them to the public internet.

Custom Domain Names:

With Private Zones, you can create custom domain names tailored to your organization's needs. This capability is particularly useful for internal applications, services, and resources that require domain-based access within your private network.

Enhanced Security:

By utilizing Private Zones, you can enforce strict access controls and security policies for DNS resolution within your private network. This helps prevent unauthorized access and ensures that only authorized users and resources can resolve domain names.

Integration with Virtual Cloud Network (VCN):

Private Zones seamlessly integrate with OCI's Virtual Cloud Network (VCN) infrastructure, allowing you to associate domain names with specific VCNs and subnet configurations. This integration enables efficient and reliable DNS resolution for resources deployed within your VCN environment.

Scalability and Performance:

OCI's Private Zone service is designed to scale with your organization's growing infrastructure requirements. It offers high availability, reliability, and low-latency DNS resolution, ensuring optimal performance for your private network resources.

Centralized Management:

Private Zones in OCI provide a centralized management interface for administering domain names, DNS records, and associated configurations. This centralized approach simplifies the management of DNS resources across your organization's infrastructure.

In part 2, we will be creating Private view, associate private view to the VCN and add record to the private zone.
