Cloud-Based DNS: Top 5 Reasons to Make the Move

DNS is critical to the performance and reliability of your internet applications and cloud services. DNS outages or slow DNS performance can lead to customer dissatisfaction, a tarnished brand image, and revenue loss. Because DNS is first link in your digital supply chain, you can’t afford to take it for granted.

Think about how you’d answer these questions today:

  • Are your in-house team and your ISP ready to handle bandwidth at scale and provide consistent performance to a global user base?
  • Does your current DNS solution offer multiple PoPs around the world and support multiple Tier 1 transit providers?
  • Are you ready to prevent and mitigate attacks: Do you have the 4x bandwidth capacity to withstand even a modest DDoS attack?
  • Can you provide real-time global performance data gleaned from over 200 billion data points in order to offer intelligent traffic steering?

A managed DNS service helps you address all these questions and more. By moving DNS to the cloud, you can significantly reduce the risk associated with the availability constraints, security vulnerabilities, and performance limitations of your current DNS solution, be it a homegrown system or legacy DNS from your ISP or hosting provider.

Five critical reasons to move to a cloud-based DNS provider now

  1. Dedicated DNS design and management resources. Designing, operating and protecting a global DNS network is resource-intensive, expensive, and time-consuming to implement in-house. ISPs may lack the knowledge and expertise to deliver enterprise-grade DNS performance. You can achieve the results you want by turning over the operation of your DNS to experts and freeing up your internal staff to work on more strategic projects.
  2. Faster DNS resolution. To accelerate DNS resolution, find an experienced provider who operates large-scale anycast networks with multiple PoPs around the world. In order to scale, you’ll need real-time traffic steering that combines policy (load balancing, failover) and real-time data related to performance and availability.Implementing advanced traffic steering requires that you address the need to reduce latency, mitigate the impact of DDoS attacks (or route hijacks) and balance loads globally by region or between CDNs.
  3. Improved edge security posture. DNS providers take a multilayered approach to security, employing a variety of measures to establish trust and defend against threats. They have dedicated security experts who closely monitor industry trends and proactively update security systems and practices to thwart malicious attacks and mitigate risks. Few in-house or ISP-based DNS providers are able to deliver that level of security.Multiple, geographically distributed DNS name servers eliminate single points of failure and ensure continuous service in the event of individual server problems or network outages. Anycast also provides fundamental security advantages over unicast—mitigating security threats by concealing the addresses of individual servers and automatically distributing attacks across a collection of compute resources.
  4. “Always on” availability and performance. Users that come to your site need consistent performance every time. There are a number of techniques that DNS providers have developed to help you achieve your organization’s uptime goals. Managed DNS can provide redundancy and failover protection that ensures access even in the event of a failure. First, find a service that operates out of geographically distributed PoPs with multiple Tier 1 transit providers at each PoP.When you’re looking for additional availability assurance, you can implement a secondary DNS server—on a separate network, supported by a different provider. Or if it’s failover you’re considering to ensure business continuity, you may choose a primary-primary failover strategy or a primary-secondary approach—or you may even choose a primary-hidden secondary. The choice is yours.
  5. Unmatched DNS expertise and network security experience. DNS service providers employ full-time DNS and network security experts. They closely monitor industry trends and proactively review and update data center systems and practices. Cloud-based DNS providers also offer 24/7 technical support that is 100 percent DNS-focused.

Make the right choice for your business

DNS speed, agility, and reliability are critical to your digital success. But creating a highly efficient DNS infrastructure takes time, money, and expertise. The good news is that you can accelerate the process by adopting a cloud-based service.

You might also consider delegating DNS resolution to a managed or cloud DNS—this can be done with minimal impact on existing systems or providers. For example, you can add managed DNS to an in-house solution using a hidden master secondary configuration. This will allow you to manage zone configuration behind your firewall, while the cloud provider resolves queries from the internet.

With the right DNS service, you can enhance user experience and improve business outcomes. Remember that not all cloud-based DNS services are the same, so be sure to select one with a worldwide DNS infrastructure and experienced resources to ensure your success.
