State of OpenWhisk

OpenWhisk is the first Serverless platform that gained community traction when IBM pushed the platform to Apache Foundation. Licensed under the Apache license, the platform allows developers to deploy event driven applications on any infrastructure. This implies there is an operational overhead in running the platform compared to platforms like AWS Lambda, Catalyst, Google Functions,…

Mitigating Serverless Challenges

While Serverless offer many advantages for the developers, it also imposes some constraints and challenges. Some of the architectural constraints imposed by the Serverless abstraction limits the type of applications that can be deployed on Serverless platforms. See this post about the difference between Microservices and Serverless Functions to understand where these two different architectures…

Microservices & Serverless Functions – The difference

Modern developers often confront terms like microservices and serverless functions used in conversations, at times without much of delineation between the two terms. This has lead to some confusion among the developers, leading to picking the wrong technology stack for their needs. In this blog post, we will try to distinguish the difference between these…

Knative: Is it ready for production?

As Kubernetes and AWS Lambda gained traction among developers, there was a clear need for a serverless abstraction on top of Kubernetes. Knative is an open source project, originally started by Google in collaboration with IBM, Red Hat and VMware, that provides an abstraction for developers to run their code without having to manage the…

Serverless & Big Data: Is It A Good Fit?

Serverless gained traction among the developers because it allowed them to easily deploy small chunks of code without having to worry about bringing up servers. The early success due to the seamless deployment of event driven functions as well as the constraints imposed by early Serverless platforms like AWS Lambda on developers have given an…

The Pros and Cons of AWS Lambda

Ever since Amazon Web Services launched AWS Lambda in 2014 as a Serverless platform, it has been steadily gaining traction among developers. AWS Lambda allowed developers to deploy small chunks of code and scale seamlessly at a very low cost. Developers could do this without having to manage the underlying servers. This productivity advantage offered…

Event Driven Compute Using Zoho Catalyst

Today’s leading applications are so dynamic that sometimes it requires developers to use complex tools and infrastructural changes to adapt and facilitate them. Cases like running OCR on images, running filters and resizing images or even sentiment analysis on texts are very common use cases that require one part of the system to react to…

Triggering Serverless Functions with Event Sources

Serverless Functions are well suited for Event driven applications and the event sources trigger the invocation of the functions. Events are treated as first class citizens and Functions as a Service (FaaS) providers like AWS Lambda, Azure Functions, Catalyst and Google Functions provide support for various services to act as the event source that triggers…

Is Open Source Even Relevant In Serverless

Open source has been intertwined with enterprise software for more than two decades and, with the increased adoption of cloud computing, the role of open-source software has only been increasing. If we look at the hype around containers, it is completely driven by open source. As Serverless gains traction, driven mainly by the higher-level abstractions,…
