The Difference Between Traditional DNS, DHCP, and IPAM (DDI) and NS1 Cloud-Managed DDI

Bringing core network services into the cloud helps modern enterprises minimize complexity, keep up with a fast-changing business environment, and deliver the best application experiences for employees and customers

Companies have accelerated digital transformation to meet business goals that depend on the ability to consistently deliver superior application experiences. They are racing to cloud and microservices architectures and moving to the edge to better support the massive surge in connected devices and more widely distributed audiences.

However, legacy core network infrastructure - like DNS, DHCP, and IPAM - can’t keep up. They're unable to provide the flexibility for local compute and autonomy, with centralized control of the distributed edge, that modern network configurations require.

That’s why we’re thrilled to announce the release of NS1’s Cloud-Managed DNS, DHCP, and IPAM (DDI). NS1’s Cloud Managed DDI is built for the distributed edge - highly dynamic and distributed networks that need cloud automation and scale.

With Cloud-Managed DDI, enterprises can manage core network services from the cloud, with edge services deployed wherever and whenever needed. Keep reading for an overview of how Cloud-Managed DDI works, and some of the key pain points it solves for distributed enterprises compared to traditional DDI.

Register for our upcoming webinar, Building a Resilient, Distributed Enterprise with Cloud-Managed DNS, DHCP and IPAM (DDI), to see how Cloud-Managed DDI accelerates digital transformation and builds resilience at distributed enterprises.

Flexible Deployments

Digital transformation initiatives are driving enterprises from traditional on-premises to hybrid cloud solutions. However, unlocking the full value and potential of digital transformation hinges upon your core network services - DDI. And the legacy approach to DDI - on-premises and appliance-based - lacks the agility, scale, redundancy and multi-cloud capabilities required to support the transformation to highly distributed, edge enabled, multi-cloud infrastructures.

Building on our years of experience with NS1 Managed DNS, cmDDI is cloud-managed and ideally suited to this market shift to hybrid, partially on-premises, partially in-many-cloud deployments. Edge services can be deployed in a customer’s private cloud, on-premises or on select network devices. They are lightweight and can be fully managed via the portal or API, integrating with NetOps and DevOps approaches.

Simple Yet Powerful Change Propagation and Traffic Management

In today’s enterprise environment, things change quickly. Infrastructure may be spun up and down in minutes. Traditional DDI - delivered as a monolithic application or physical appliance - cannot meet the required agility, scale, and flexibility that is needed for the modern era.

Bringing DDI into the cloud enables you to propagate changes within seconds. With NS1 Cloud-Managed DDI, you can publish DNS zones to our Managed DNS network, an NS1 DNS on-premises instance, or an instance hosted in a customer’s cloud with just a simple API call or a few clicks in the portal. DNS zones use DNS views to provide different zone contents based on a DNS client's location. Our Filter Chain technology enables even more advanced options, such as control over DNS record answers based on a client’s application service, up/down status, service load, and much more. It provides the flexibility and programmability needed to manage today’s network infrastructure.

Local Survivability

Key concerns raised with cloud-managed services typically center around local survivability and ease of upgrades. Our Cloud-Managed DDI edge services will continue to operate, even if the connectivity with the management plane in the cloud is severed. DNS will continue to resolve and DHCP will continue to issue leases.

Local configurability is also available, allowing for service level changes to be made without cloud connectivity (e.g. adjusting the destination of a DNS forwarder). And future versions of Cloud-Managed DDI will also enable scaling of services independent of control-plane availability. Edge service upgrades are seamless and support zero down-time upgrades.

In contrast, service upgrades with traditional DDI often involve a full restart of the service or appliances, which comes with the risk of issues or outages.

Scale, Reliability, and Security

Our cloud-managed solution brings all the benefits you would expect from a SaaS solution. Customers get automated backups from NS1, redundancy, and scalability, which makes it easier to implement and to maintain your DDI services. Of course, all data is encrypted in transit and at rest as per industry best practices.

In traditional on-premises DDI these critical responsibilities rest with the end-user and are restricted by the form factor of delivery; backups, data redundancy and encryption at rest are less flexible compared to what can be delivered with a cloud-based management plane.

NS1 Cloud-Managed DDI meets the modern networking requirements that legacy systems cannot. To learn more, register for our upcoming webinar: Building a Resilient, Distributed Enterprise with Cloud-Managed DNS, DHCP and IPAM.
