They used different search technology: DiscoverOrg used elasticsearch and ZoomInfo used Apache Solr.

They mostly used the same code-related tooling: they used Java for the backend, Javascript for the front end, and even used the same frameworks for both.

In looking at the two legacy platforms, ZoomInfo determined the following: Notice that the process is designed to stop once a viable environment is identified.

If not, what environment should ZoomInfo use instead? If neither legacy environment is suitable for the combined platform, determine the new environment to use instead.

If not, do either of the existing platforms make sense for the combined platform either as is or with a minimum of adjustment? If so, then use that platform’s legacy environment as the starting point for the combined environment and port code or recreate features from the other legacy environment as needed.

Are the two platform development environments similar enough to share code directly or with a minimum of updating? If so, then create a merged environment capable of using code and other elements of both legacy platforms.

There were potentially three sequential stages to evaluating the legacy platforms and their viability for use in the new combined platform as shown in this flowchart:

How much of the planned functionality in the combined platform draws more closely from each legacy platform.

The cloud platform used by each legacy platform.

The search technologies used to return data to users.

The programming languages and frameworks used to write code.

In order to evaluate the development environments and their suitability for the combined platform, ZoomInfo looked at several things. In doing so, some features were retained from DiscoverOrg, some from ZoomInfo, and sometimes a new version of an existing feature was created (of course, there were lots of new features as well).Īs part of this process, the ZoomInfo application team looked at the existing code base, technology, tooling, and processes used to develop each platform to see how compatible they were and whether code could be reused from both or if it would be easier and more efficient to start from the environment of one platform and port over features from the other one as needed. ZoomInfo recently created the combined DiscoverOrg and ZoomInfo platform to replace both the legacy DiscoverOrg and the legacy ZoomInfo platforms.
