Moving from custom AI solutions to cloud-based AI services

Artificial intelligence technologies can be helpful in numerous use cases such as analyzing facial emotions, classifying cancer types, detecting malware, recognizing speech, and enhancing car insurance services.

But since AI is a resource-hungry technology, developing intelligent algorithms from scratch may be costly. Therefore, many organizations use AI as a service (AIaaS) and AI PaaS products from cloud vendors to experiment with AI-based technologies. Let’s explore the main differences between these two services:

AIaaS vs AI PaaS

Now, let’s take a closer look at each of these services.

Artificial intelligence as a service

AIaaS covers ready-to-use AI products and services (with built-in ML and DL algorithms) for data management with limited customization capabilities. Such software helps organizations with advanced trend analysis, pattern matching, predictive analytics, and other data management tasks. AIaaS services usually are affordable for small and midsize businesses.

There are dedicated AI solutions meant for solving specific tasks like:

  • Processing and analyzing big data
  • Processing specific types of data (image, video, speech)
  • Building prediction models
  • And more

Common AIaaS use cases are:

  • Chatbots
  • Digital assistant solutions
  • ML and AI frameworks that help developers build their own models

Today, however, there’s an emerging trend among AI service providers: they’re expanding their offerings to full-scale platforms for AI developers. This is where AI platforms as a service come into play.

Artificial intelligence platform as a service

AI PaaS is a set of AI and ML platform services for building, training, and deploying AI-powered application functionalities. Since by definition, PaaS services help users develop, run, and manage applications, AI PaaS can help organizations create AI-based products without the need to purchase and maintain infrastructure.

This term usually refers to end-to-end solutions like cloud platforms that allow businesses to use AI-based services they need on a pay-per-use or pay-per-service basis. To provide comprehensive intelligent solutions that can work out of the box, such platforms often include managed sub-services and third-party APIs.

Major cloud service providers offer both AIaaS and AI PaaS solutions within a single platform. So although these services are different, they are often combined in a single product. In this article, we mostly focus on the AI PaaS model. Now let’s take a look at the key elements an AI PaaS service may include.

AI PaaS key components

First, let’s look at the concept of AI PaaS from the perspective of the classic platform as a service (PaaS) model.

With PaaS, a cloud vendor provides an environment for building, deploying, and maintaining applications. A basic PaaS environment usually includes two main groups of components required for application development: infrastructure and a platform.

Basic PaaS environment

Now, let’s go back to AI PaaS. AI itself is all about processing enormous amounts of data, which, in turn, requires extensive computing power. This is why, similar to the standard PaaS model, many AI service providers offer infrastructure resources, computing resources, and virtualization capabilities. All the big data required for training ML models and improving AI solutions needs to be stored somewhere. This is why data storage resources are a common element of AIaaS and AI PaaS products.

What distinguishes AI PaaS from a basic PaaS model are two components: pretrained ML models and AI APIs.

2 key components of AI PaaS

Let’s take a closer look at each of these components.
