TL:DR
- Legacy DNS, DHCP & IPAM services create fragmented implementations across hybrid multicloud environments, increasing operational risk & limiting resilience.
- Modern DDI solutions integrate these services as virtual network functions with automation, providing unified management & multicloud redundancy capabilities.
- Reference architectures enable consistent DDI deployments using Infrastructure as Code tools, eliminating configuration errors & simplifying compliance.
If you’ve worked in IT for long enough, there’s a good chance you’ve had the following experience:
- You: “It’s not DNS… There’s no way it’s DNS…”
- Narrator: “It was, in fact, DNS.”
Because of course, it’s always DNS. It’s so familiar that it’s become a meme for those of us in the industry. However, knowing what to do about it isn’t easy, and the emergence of hybrid multicloud only adds to the complexity.
Enterprises have traditionally managed DNS, DHCP and IPAM as separate solutions, each deployed, managed and updated manually over time. While this model was sufficient in more static environments, it’s misaligned with the realities of rapidly evolving hybrid multicloud architectures.
As organizations expanded into the cloud, many standardized on the native capabilities of their initial platform to accelerate adoption and simplify early operations. Over time, this has led to fragmented DDI implementations that are tightly coupled to individual environments. The result is increased operational risk: When a cloud platform experiences a disruption, particularly one with regional impact, environment‑specific DDI services leave enterprises with limited flexibility and resilience when they need it most.
Companies should fear losing direct control and visibility over these core network services. Cloud-hosted DDI often means relying on third-party infrastructure and siloed management with no single source of truth, a situation that has led to IP address conflicts, configuration errors, and outages in practice. They also worry about vendor lock-in, since many cloud-based DDI solutions are tied to one provider and lack true multicloud or hybrid support. This prevents unified management across different environments and limits future flexibility.
Additionally, offloading DDI raises data sovereignty and compliance concerns. In a recent survey, 84% of IT leaders said their organizations are concerned about data sovereignty. The three most commonly named concerns in the survey were compliance with regional data protection laws such as GDPR and CCPA, security risks associated with foreign data centers, and data residency requirements from clients or partners.[1]
To overcome these limitations, enterprises need a modern, resilient and cloud-agnostic approach to DDI services. This will better position them to address the complexity that inevitably arises when running a hybrid multicloud architecture. Instead of trying to update individual solutions manually, they’ll have integrated DDI services that automatically react to changing vendors and environments.
Modern DDI must evolve for hybrid multicloud
In the past, many enterprises looked to a particular vendor to acquire and manage DNS and DHCP. As a result, they ended up with siloed, monolithic servers that were only good for one very specific purpose. Also, IPAM was typically a very manual process. In some cases, it was literally nothing more than a spreadsheet sitting on a network engineer’s desktop. This setup made the entire organization slow-moving and unable to adapt whenever challenges or opportunities arose.
Many enterprises moved to the cloud in an effort to increase their infrastructure flexibility. With networking, things didn’t always work out that way. Having to integrate multiple cloud and hybrid environments has made managing IPs significantly more difficult, especially for those that continue to rely on legacy services. The possibility of issues such as overlapping IPs increases, and the environment changes too quickly to be adequately managed via traditional, manual methods.
To address this, modern DDI solutions must incorporate automation and enterprise-grade workflows and tools. Some vendors, including Equinix partner Infoblox, are industry experts in this space and offer products that promise a unified, cloud-agnostic DDI framework. This framework is based upon DNS, DHCP and IPAM tools deployed as virtual network functions (VNFs) on Equinix Network Edge and linked via flexible multicloud networking solutions such as Equinix Fabric®, our software-defined interconnection solution.
This framework works well across clouds and provides enterprise IT leaders with a single pane of glass to view their entire DDI solution. It also offers security and resiliency via multicloud redundancy and full auditability of the solution, which is essential for sovereignty and compliance reporting. The framework can shift workloads seamlessly between clouds, so an outage in one particular cloud environment doesn’t automatically translate into an outage for the entire business.
Modern DDI frameworks also provide reference architectures to help simplify deployment and enable a reusable approach to DDI services.
Why reference architectures matter for modern DDI
A good reference architecture takes the guesswork out of deploying modernized DDI in a hybrid multicloud environment. An enterprise can execute deployments and configurations based upon a proven reference architecture that was designed, tested and certified by experts in their respective fields, such as Equinix and Infoblox. This helps IT leaders feel completely confident that they’ll get the deployment right the first time, and every time thereafter.
These reference architectures are specifically geared for the needs of critical services such as DDI. They help ensure authoritative, recursive DNS, automated DHCP and centralized IPAM capabilities, all backed by scalable network infrastructure.
They’re also reusable and seamlessly integrated with Infrastructure as Code (IAC) tools such as Terraform and Ansible. This allows enterprises to expand their modern DDI solutions into new regions by simply copying and pasting their deployment design based on the validated reference architectures. The solutions now work the same wherever they’re deployed, providing consistency and standardization on a global scale.
Reference architectures can also be designed to simplify compliance and reporting for major security and privacy regulations. They can also include role-based access control (RBAC), detailed audit trails and simplified software updates to help team members ensure secure and accountable administration.
Deploying based on a validated reference architecture, when properly coupled with IAC automation tools, also removes the risk of human misconfiguration errors. They’ve been tested and proven by real enterprises, and all the knowledge and expertise that went into designing them is embedded for future use. Your organization can continue to benefit from this expertise over time, without needing direct access to the experts themselves. Thus, the reference architecture becomes your single source of truth for how DDI solutions should be deployed within your organization. You no longer have to worry about employee turnover causing disruption when key expertise walks out the door.
How modern DDI delivers better results across hybrid multicloud environments
A DDI solution delivers better results in hybrid multicloud environments by unifying and automating core network services across all clouds and on‑premises systems. Instead of each cloud platform having its own siloed DNS or IPAM, modern DDI provides a single point of control (often via a cloud-based portal and API) to manage all DNS zones, DHCP servers and IP addresses centrally.
For example, when a new workload in one cloud is assigned an IP address via DHCP, the DDI system instantly updates the global IPAM database and even registers or updates the DNS records enterprise-wide. These real-time interactions between DHCP, IPAM and DNS ensure every environment stays in sync. This prevents IP conflicts, eliminates stale DNS entries and keeps name-to-IP mappings accurate without manual effort. It also removes the difficulties of managing (or remembering) IPv6 addresses. With available addresses in the undecillions (yes, that’s a real number), automating the management of enterprise IPs is now extremely important.
By serving as the authoritative source of truth for network addressing, a modern DDI can enforce consistent network configurations and policies across heterogeneous environments, which greatly reduces configuration errors (a leading cause of outages) and improves overall reliability.
A modern DDI solution, such as Infoblox DDI on Equinix Network Edge, enhances security and operational efficiencies by providing global server load balancing for DNS traffic, which enables high availability, improved fault tolerance, and robust disaster recovery. It also offers built-in enterprise-class tools to detect inconsistencies in one environment and then perform an automatic failover into a different environment before those inconsistencies turn into outages.
