New Relic, the SaaS applications performance management platform, announced a major update to that platform today. Instead of ripping off the band-aid all at once, the company has decided to take a more measured approach to change, giving customers a chance to ease into it.

The new platform, called New Relic One has been designed to replace the original platform, which was developed over the previous decade. The company says that by moving slowly to the new platform, customers will be able to take advantage of new features that it couldn’t have built on the old platform without having to learn a new a way of working.

Jim Gochee, chief product officer at New Relic says that all of the existing tooling and functionality will eventually be ported over or reimagined on top of New Relic One.”What it is under the covers for us is a new technology stack and a new platform for our offering. We are still running our existing technology stack with our existing products. So we’re [essentially] running two platforms in two stacks in parallel, but all of the new stuff is going to be built on New Relic One over time,” he explained.

By redesigning the existing platform from scratch, New Relic created a new, modern, more extensible model that will allow it to plug in new functionality more easily over time, and eventually even allow customers to do the same thing. For now, it’s about changing what’s happening under the hood and providing a new user experience in a redesigned user interface.

“New Relic One is very pluggable and extensible, which makes it easier for our own teams to build on, and to extend and expand, and also down the road we will eventually get to the point where partners and customers will be able to extend our UI themselves, which is something that we’re very excited about,” he said.

Among the new features is support for AWS Lambda, the company’s serverless offering. It also enables users to search across multiple accounts. It’s not unusual for customers to be monitoring multiple accounts and sub-accounts. With New Relic One, customers can now search across these accounts and find if issues have cascaded more easily.

In a blog post introducing the new platform, CEO Lew Cirne acknowledged the growing complexity of the monitoring landscape, something the new platform has been specifically designed to address.

“Unlike today’s fragmented tools that can deliver a bag of charts and metrics with a bunch of seemingly unrelated numbers, New Relic One is designed to cut through complexity, provide context, and let you see across artificial organizational boundaries so you can quickly find and fix problems,” Cirne wrote.

Nancy Gohring, a senior analyst at 451 Research says this flexibility is a key strength of the new approach. “One of the most important updates here is the reworked data model which allows New Relic to offer customers more flexibility in how they can search the operations data they’re collecting and build dashboards. This kind of flexibility is more important in modern app environments that are more complex and dynamic than they used to be. Everyone’s environment is different and digging for the cause of a problem is more complicated than it used to be,” Gohring told TechCrunch. The new ability to search across accounts should help with that.

She concedes that having parallel platforms is not ideal, but sees why the company chose to go this route. “Having two UIs is never great. But the approach New Relic is taking lets them get something totally new out all at once, rather than spending time gradually introducing it. It will let customers try out the new stuff at their own pace,” she said.

New Relic One goes live tomorrow, and will be available at no additional cost to New Relic subscribers.
