We leverage two things from Managed DNS that we couldn't do with any other solution. One is their filter chain technology, which allows us to shift some of the intelligence we need for the traffic steering to the DNS. The second one is data sources, which enables us to manipulate multiple records simultaneously using NS1's internal message DOS. In our case, we are trying to direct the traffic in over 150,000 different NS1 records to an arbitrary set of repeating responses. If we have about 1,000 endpoints, that translates to around 150,000 records. Assuming there's an even distribution, so every time a server fails or an endpoint goes on a level, we would have 150 updates. With NS1, we have one, so this had an even more significant effect. There are situations where we have thousands of specific records sharing the same responses. In that case, there is one update instead of thousands and thousands. When we chose Managed DNS in 2014, it was the only solution that could do what we wanted, but I'm not sure about the current state of the market. The NS1 API is an API on top of a managed DNS. It's not an afterthought. It's not like the solution existed. Someone was sending updates by email. Then a product manager came along and said, "Hey, there is this cool thing. It's called an API. Maybe we should do it?" And they are like, "Okay. Let's do it." In the case of NS1, they thought about how to use an API to manipulate and retrieve the stuff. It's supposed to be API-driven. Also, NS1 doesn't have hidden features that would not be available over the API. Even their dashboard is built on top of the API. You can leverage all the functionality programmatically. That's what we do. We don't use their native integrations because we have been customers before these integrations and real-time telemetry existed. Our solution isn't leveraging either of those. Instead, we leveraged their API integration, which was the first thing that existed. Indeed, the API is at the core of how we use Managed DNS. No one goes to the dashboard or manually clicks anything. Everything goes via the API, and we perform hundreds of changes every minute. The API automatically drives everything, so that's the integration we leverage. We don't use the Pulsar Active Steering feature because we don't have a website. Our solution is being used as an API for other solutions. You can put the Pulsar agent on the website and feed NS1 the information. In our case, we are integrating into third-party sites. We cannot put our JavaScript on their websites for NS1 to provide the data, so we don't.

We use the geo load balancing functionality and there are a couple of things that are helpful there. But the language itself is something we had to get used to a little bit. Some of my folks made a few mistakes in rolling out the Filter Chain. It doesn't return all of the multiple results by default. It returns only one. So we have to add a bunch of operations, like geo-target by first selecting a group in terms of regional proximity and then shuffle the list of potential endpoints and then select the first one. The Filter Chain setup is a bit hard to grasp at first. It would also be nice to have a way to simulate changes in addition to staging. Also, right now, as far as I understand, there is no way to do atomic changes to a DNS configuration. You need to make changes record by record and apply. But if someone wants to do more complex stuff like, for example, if I want to migrate from a CNAME to an A record being served, or vice versa, that's typically something that involves first taking out all of the CNAMEs and then adding all of the A records. That would require some downtime. It would be a lot easier if I could just have the new full record with the CNAME or A record, and then be able to replace the nodes directly in a single operation and I don't think they have that.

The provisioning is great. They have an API service that is simple to use and very quick. The changes that we make are replicated worldwide in a matter of usually milliseconds, sometimes seconds. They are done very rapidly. That's something that's obviously priceless when we're dealing with things like DNS. It is great as an API-first platform for DNS and application traffic management. It is very simple to use. It allows us to rapidly provision and deprovision things. We are all around happy with the solution. From a metrics standpoint, the solution that we came from had no metrics. So, it has been great. Their service team is excellent in taking the time to provide reports for both growth and strategic planning. It has been great.

"The provisioning is great. They have an API service that is simple to use and very quick. The changes that we make are replicated worldwide in a matter of usually milliseconds, sometimes seconds. They are done very rapidly. That's something that's obviously priceless when we're dealing with things like DNS."
"Their Pulsar filters allow us to collect RUM metrics from our users so that we can determine the best paths for our users to take. That has been very useful in providing the best user experience, and for responding to and recovering from downtime of our multiple CDNs."
"One of the features that is non-standard and that is very useful is the filtered DNS. We have set up our external VPN, which is what all our employees connect through, to use this feature. It's geolocation-aware. In that way, for India we set it up so that these are the servers that should be supporting things, and in the UK these servers, in the U.S. these servers, and in Sweden these ones."

Room for Improvement

IBM NS1 Connect requires enhancements in its testing capabilities and API simulation to enable pre-deployment testing. Users desire faster operations, bulk change features for modifications, and improved reliability in monitoring to avoid false positives. The UI needs refining for finer search functions and reporting metrics. Managing internal and external DNS separately would increase security. Improved usability of geo-load balancing and Filter Chain, along with atomic DNS changes, would prevent downtime during migrations.

"The reporting metrics are great from an API standpoint, but it would be a little bit nicer if there was some type of dashboard around that. There should also be some type of reporting that's more executive-level focused."
"I would love to see improvement in the testing capabilities they provide. They have a simulate-filter feature so that you can simulate how your traffic would flow, based on their Filter Chains. I believe that was shut off for quite some time. Having that as a way to test our load-balanced CDN structure would be fantastic."
"When we first deployed, we flipped the switch, and it didn't work as well as we expected. It wasn't a complete outage, but we had issues in some places with some customers. The NS1 team went out of their way to resolve it on Thanksgiving. We have a post about it on our blog. We called it "Black Thursday.""

The managed DNS service contributes to quicker software development cycles by reducing manual interventions and alleviates the need for additional server infrastructure, making it a valuable investment.

Pricing

IBM NS1 Connect offers competitive and fair pricing, positioned aggressively compared to competitors. Enterprise users indicate costs around $30,000 monthly, appreciating the value and features compared to previous choices like Dyn. Pricing accommodates high volumes, such as 4.5 billion requests, with capabilities for load balancing and DNS management. Users note satisfaction with licensing, acknowledging the potential for overage costs and appreciating tailored, flexible pricing plans that meet organizational needs without complaints from decision-makers.

"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."
