The availability of tremendous computing power in the cloud was one of the factors behind the machine learning revolution. Thus, it is not surprising that there are cloud-based services emerging, aimed at machine learning specialists. But which one to pick?

Cloud-based services are not that new in fact. Every user has at least one email account, making him or her a cloud user – he or she has no idea where the emails are stored or how much computing power was used to send the message. Usually – nobody cares. 

What is Machine Learning as a Service (MLaaS)?

When it comes to machine learning, the access to the computing power was essential to make this technique popular – the company needs not a server farm to develop a model and use it to automate daily tasks. But still, there are multiple tools to use and processes to keep eye on when it comes to developing a model. Business reality is never as straightforward as the development theory. 

Machine Learning as a Service (MLaaS) is basically an umbrella term for a set of cloud-based tools. These tools aim to support the daily work of data scientists and data engineers in the way cloud based office suites have revolutionized the office environment. The MLaaS tools support collaboration, version control, parallelization and other processes that otherwise would be troublesome. Also, larger vendors deliver easy ways to integrate their MLaaS services with the rest of their portfolio, automating the deployment process or enabling ones to enrich daily tasks with machine learning-based tools. 

Also, there is a growing need for MLaaS tools. The AI market worldwide is getting only bigger, According to IDC estimations it will reach up to $156.5 billion of worth by the end of the year.
