FaaS

Use Binary Data as Function Input and Output

In the previous article, we demonstrated how a Second State FaaS function could handle text-based input and output. Through JSON support, we can encode arbitrary data types into text. However, for functions focused on media processing, binary-based input and output is far more efficient and more performant. In this article, we will show you how to use a Second State FaaS function to add watermark to an image. The source code for the watermark example in this article is available on Github.…

High performance and safe AI as a Service in Node.js

Today’s dominant programming language for AI is Python. Yet, the programming language for the web is JavaScript. To provide AI capabilities as a service on the web, we need to wrap AI algorithms in JavaScript, particularly Node.js. However, neither Python nor JavaScript by itself is suitable for computationally intensive AI applications. They are high-level, ie, slow, languages with heavy-weight runtimes. Their ease-of-use comes at the cost of low performance. Python got around this by wrapping AI computation in native C/C++ modules.…
