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.
