Machine Learning as a Service (MLaaS): How Google Cloud Platform, Microsoft Azure, and AWS are democratizing Artificial Intelligence

There has been a huge shift in the way that businesses build technology in recent years driven by a move towards cloud and microservices. Public cloud services like AWS, Microsoft Azure, and Google Cloud Platform are transforming the way companies of all sizes understand and use software. Not only do public cloud services reduce the resourcing costs associated with on site server resources, they also make it easier to leverage cutting edge technological innovations like machine learning and artificial intelligence. Cloud is giving rise to what’s known as ‘Machine Learning as a Service’ - a trend that could prove to be transformative for organizations of all types and sizes.

According to a report published on Research and Markets, Machine Learning as a Service is set to face a compound annual growth rate (CAGR) of 49% between 2017 and 2023. The main drivers of this growth include the increased application of advanced analytics in manufacturing, the high volume of structured and unstructured data, and the integration of machine learning with big data.

Of course, with machine learning a relatively new area for many businesses, demand for MLaaS is ultimately self-fulfilling - if it’s there and people can see the benefits it can bring, demand is only going to continue.

But it’s important not to get fazed by the hype. Plenty of money will be spent on cloud based machine learning products that won’t help anyone but the tech giants who run the public clouds. With that in mind, let’s dive deeper into Machine Learning as a Service and what the biggest cloud vendors offer.

What does Machine Learning as a Service (MLaaS) mean?

Machine learning as a Service (MLaaS) is an array of services that provides machine learning tools to users. Businesses and developers can incorporate a machine learning model into their application without having to work on its implementation. These services range from data visualization, facial recognition, natural language processing, chatbots, predictive analytics and deep learning, among others.

Typically, for a given machine learning task, a user has to perform various steps. These steps include data preprocessing, feature identification, implementing the machine learning model, and training the model. MLaaS services simplify this process by only exposing a subset of the steps to the user while automatically managing the remaining steps. Some services can also provide 1-click mode, where the users does not have to perform any of the steps mentioned earlier.

What type of businesses can benefit from Machine Learning as a Service?

Large companies

Large companies can afford to hire expert machine learning engineers and data scientists, but they still have to build and manage their own custom machine learning model. This is time-intensive and complicated process. By leveraging MLaaS services these companies can use pre-trained machine learning models via APIs that perform specific tasks and save time.

Small and mid-sized businesses

Big companies can invest in their own machine learning solutions because they have the resources. For small and mid-sized businesses (SMBs), however, this simply isn’t the case. Fortunately, MLaaS changes all that and makes machine learning accessible to organizations with resource limitations.

By using MLaaS, businesses can leverage machine learning without the huge investment in infrastructure or talent. Whether it’s for smarter and more intelligent customer-facing apps, or improved operational intelligence and automation, this could bring huge gains for a reasonable amount of spending.

What types of roles will benefit from MLaaS?

Machine learning can contribute to any kind of app development provided you have data to train your app. However, adding AI features to your app is not easy. As a developer, you’ve to worry about a lot of other factors besides regular app development checklist, in order to make your app intelligent. Some of them are:

Data preprocessing

Model training

Model evaluation

Predictions

Expertise in data science

The development tools provided by MLaaS can simplify these tasks allowing you to easily embed machine learning in your applications. Developers can build quickly and efficiently with MLaaS offerings, because they have access to pre-built algorithms and models that would take them extensive resources to build otherwise.

MLaaS can also support data scientists and analysts. While most data scientists should have the necessary skills to build and train machine learning models from scratch, it can nevertheless still be a time consuming task. MLaaS can, as already mentioned, simplify the machine learning engineering process, which means data scientists can focus on optimizations that require more thought and expertise.
