Kalix: A new and innovative approach to application development


For many decades, programming has been around, and the internet has gone through various phases. Coding is now more valued than ever, and given the proliferation of technology, there is an increased demand for the development of creative applications with ease. In response to this, We see a growing number of platforms being available to help optimize the software development effort and deliver Business outcomes. In this blog, We are going to talk about one such revolutionary platform - Kalix by Lightbend Technologies that makes developing and managing applications much simpler.

So, what is Kalix? It is a Platform-as-a-Service (PaaS) developed by Lightbend that deals with the typical problems encountered by developers. When creating an app, many steps have to be taken into consideration, and companies often invest heavily in something that might not be successful. Kalix has been designed to reduce this risk.

What is Kalix?

Kalix is a PaaS program developed by Lightbend to tackle the software development related tasks that have usually been tackled by developers. Developing an Application comes with multifarious challenges and it has a lot of steps that a developer needs to take, a lot of different constraints that he/she has to measure, often at times this leads to engineering organizations and developers to spend considerable time on it. Its a Platform as a Service (PAAS) Software product which is cloud-based, database-less, server-less, broker-less and helps in optimizing the software development & deployment.

How is it different? Key USPs of the PaaS product

Kalix takes an API-first design approach, which entails the breaking down of application into microservices-based Architecture. The platform helps in alleviating a lot of pain that us, software developers face on a daily basis to develop applications. The people who have developed enterprise applications must have taken a long sigh when they must have read this, the pain and the effort they suffer and put in. Kalix is their hero, it manages everything on their behalf asking them to be solely focused on the business logic of the application and to write code specifically for that. Kalix is a step-forward in the Akka Framework by Lightbend by making it even more developer-friendly. Kalix is kubernetes-less, broker-less, database-less and serverless making it a developer’s best friend as shared below -.

Kalix is a serverless platform which makes sure to take care and manage the servers for your application, this takes away the daily pain of managing and maintaining these servers. Gone are the days where you were developing Java Applications and connecting your JDBC to your Tomcat or Jelly server, Kalix is here to introduce you to the new age of developing applications.

Kalix is a Kubernetes-less platform which takes care of all of the Docker containers that are we have created for your applications. A docker container contains all the pieces of softwares and everything needed to run it, all the dependencies, libraries etc.When developing a Java Application especially a Java EE application using Microservices architecture, the developer usually uses docker containers to store various services of the application and Kubernetes is a platform which is used to maintain and manages these containers. When there is an application which requires a lot of containers for all of its services it becomes difficult to manage them. Kalix takes care of all this hence promoting their message of “More Dev and less Ops”

At the same time, Kalix is also Database-less which means that developers do not need to worry about maintaining and modifying databases as well. This makes it perfect for data-centric use cases like digital twins for IoT, real-time financial services, telemedicine, streaming media or gaming.
