Should You Build or Buy Your Data Science Platform?

Source: Deep Learning on Medium

An increasingly common theme among many vendors exhibiting solutions at conferences for data scientists is AutoML data science platforms. It seems like every company has their own slant for how to automate the machine learning process. There are some pretty impressive and innovative products out there and I reviewed the state of the industry back on January 31, 2019. In this article, we’ll update the state-of-the-art and pose an important question on the minds of many data scientists: “Should I use an auto ML platform, should I build my own, or should I just keep on doing machine learning like I’ve always done it?”

Auto ML Platforms Abound

I’ve taken some time to survey the big data ecosystem of companies to come up with an extensive list of the most prevalent data science & ML platforms that offer some sort of automation. Each one has a somewhat different take on what data scientists need to help them in their work. The common theme is to stretch the skills of the data scientist to address the shortage of data science expertise.

Tradeoffs for Building Your Own?

Deciding whether to adopt the methodology and overarching philosophy of a commercial auto ML tool requires much consideration. This is a strategic business decision and more often than not, the decision maker is going to be the Chief Data Scientist (or equivalent) of the organization.

Many data scientists will consider tinkering as an option for coming up with a custom auto ML solution manually from scratch. Data scientists like to build things, so it’s natural that they might try to take a stab at automating the tried-and-proven methods already being used. This is not to say such a solution will compete with a product developed by a well-funded start-up, but it may be satisfactory for the problems at hand.

It may come down to a question of time and cost. Is building such a solution going to take a lot of time and expense that may take away from the company’s primary business? Of course, this path must be weighed against the time and cost involved with evaluating, buying, and adopting a commercial solution.

Data science platform vendors offer a number of essential functions such as:

  • They connect to multiple data scores and provide traditional ETL functionality.
  • They allow you to run machine learning, deep learning, NLP, and other traditional models to some degree.
  • They can display or input the model results to another system.
  • Some platforms are able to deploy to a production environment and have staging, testing, etc. built in.

All this sounds pretty good, but there are a few caveats to consider:

  • The issue of “vendor lock-in” is a real concern. What happens to customers if the company is acquired, or goes under?
  • Despite many of the platforms having APIs, and open source connectivity, they are frameworks that are very good at what they do but are generally inflexible otherwise.
  • Some vendors are slow to act on new trends. You can be more nimble by building your own. For example, when deep learning became hot and before Tensorflow or MXNet, may of the existing platforms like RapidMiner, H2O, DataRobot had no deep learning capabilities and some still do not.

It is for these reasons that data scientists may choose not to buy a commercial solution and instead work to build a custom solution for the following reasons:

  • Cost — the platform pricing may be prohibitive.
  • Flexibility — there is a desire to avoid vendor lock-in, or the framework is too narrowly focused. Using scikit-learn, Tensorflow, etc., it’s possible to build a model that is full-featured and is more suited to the data scientist’s company workflow.
  • Domain expertise — many of these platforms are great for generic problems, however, if the need is to find solutions for a very specific problem in a specific domain then it might be better to build a custom tool.
  • Existing infrastructure and expertise — if you’re running a Java shop or an R shop and have deployed a specific data warehouse/data lake, you may want to build out a solution to leverage your existing technology stack.

There may be a 3rd, hybrid approach that many companies use, specifically they employ some kind of vendor platform with a custom code system to suit their specific use cases or problem domain.


In summary, the build-or-buy dilemma centers on capital and resources. When you decide to buy, you’re optimizing your existing team’s bandwidth, you don’t have to build out admin capability like authentication and authorization etc., you have a stable and secure software platform, and when someone quits then the knowledge doesn’t leave with them. On the other hand, when you decide to build it’s exciting to build your own platform, the platform will be much more attuned to your company workflow, and you can leverage open source tools with no license fees. Of course, you could opt to continue doing data science and machine learning the “old fashioned” way with tried and proven manual methods.
