Valuable Features

IBM NS1 Connect offers valuable features like Filter Chain for geo-load balancing and filtering, API-driven automation with Terraform, and real-time telemetry. Users highlight DNSSEC for reliability and speed, Pulsar for optimal routing, and Smart Domains for traffic management. Automation and API integrations enhance deployment efficiency. The platform excels in routing, endpoint switching based on latency, and provides extensive monitoring capabilities, making it indispensable for infrastructure management, improving user experience, ensuring fast global changes, and supporting a robust API-first environment.
  • "I couldn't recommend a better product than NS1 for managed DNS and CDN load balancing right now."
  • "NS1 was the first solution that could express the logic we needed to be hidden behind the records, and we couldn't adapt any other solution to our needs."
  • "The solution's stability is absolutely perfect."

Room for Improvement

IBM NS1 Connect could enhance the API by allowing simulation similar to its UI, improve bulk change operations, and add atomic DNS changes. Users desire a more intuitive interface that facilitates finer searches and comprehensive reporting. Monitoring and telemetry need reliability improvements, and clearer pricing is recommended. Learning resources and onboarding materials are sought. Additionally, updates to DNS registry capabilities, traffic management options, and geolocation functionalities are requested, alongside resolving DNS timeout issues.
  • "I would love to see improvement in the testing capabilities they provide."
  • "When we first deployed, we flipped the switch, and it didn't work as well as we expected."
  • "We use our client in our infrastructure to communicate with NS1. This client is a bit complex in the way that it is set up. NS1 has their own client solution that you can deploy into your platform to do this, but even that is a bit complex."

ROI

IBM NS1 Connect offers significant ROI through increased application uptime and customer experience enhancement. It enables better performance and stability while reducing manual DNS management tasks by 100%. Automation cuts down the Software Development Life Cycle, saving substantial staff hours. Organizations avoid the costs of developing custom DNS infrastructure, new servers, and maintenance. They gain global control and flexibility in DNS management, improving uptime by 40% to 45% with smart traffic routing and automation, increasing efficiency and cost savings.

Pricing

IBM NS1 Connect offers competitive pricing with significant value, making it attractive compared to other market options. Enterprise users express satisfaction with the cost-effectiveness, noting fair pricing relative to enhanced features and reliability. While setup costs are manageable, and licensing aligns with expectations, some mention potential overage costs and additional fees for specific modules. Many feel that pricing is transparent, though some budgeting-conscious organizations suggest room for greater transparency in cost and licensing details.
  • "From a cost standpoint, it's certainly not the most expensive out there, and it's also not the cheapest, but it does well to balance the cost and the functionality/reliability."
  • "Everything can always be cheaper, but as it is today the pricing is fair."
  • "We pay about $30,000 a month. We used to pay about $20,000 with Dyn every month, for lower volume than we're doing right now, but it had none of the features that we have available with NS1, so it was worth it for us. It seems competitive for us, given that we're doing 4.5 billion requests."

Popular Use Cases

Organizations primarily utilize IBM NS1 Connect for enhanced DNS management and automation. It serves as a key contact point for discovering DNS, managing internet-facing traffic, and improving user experience through smart routing and low latency.
