Ansible is an automation tool created for the sole purpose of handling redundant that would otherwise slow down your development cycle. The automation tool is used in IT services such as application deployment, management, provisioning, and inter-service orchestration. In times of quickly scaling IT industries and their ever-increasing complexity of work, Ansible is like Moses created to shepherd the hapless sheep of through the valley of IT development.

Machine Learning DevOps


Infrastructure meant for traditional application development is not suitable and optimized for Machine learning operations. The mere experimental nature of the data scientist’s workflow together with the high degree viability of their computational requirements make it a daunting task to put together a DevOps machine language pipeline(MLOPS).

Kubernetes vs Docker

"Kubernetes versus Docker" is an expression that you overhear nowadays as Kubernetes turns out to be prominent as a container orchestration key. Yet, "Kubernetes versus Docker" is also a confusing expression. At the point when you separate it, these words do not mean what individuals expect, since Docker and Kubernetes are not direct competitors. Docker refers to containerization platform while Kubernetes a container orchestrator meant for container platforms. Let's discuss and break them down for clarity:

Introduction to Kubernetes


In 2017, Kubernetes (k8s) overcome the container orchestration space. For a long time, Kubernetes' opponents, for example, Docker Swarm and Mesos have been presenting their own container orchestration implements. Now the two of them helped Kubernetes inside their environments. The biggest cloud suppliers, for example, AWS, Microsoft Azure and Oracle Cloud declared Kubernetes reconciliations into their individual cloud stages. Thus, every developer would profit by learning the nuts and bolts of Kubernetes. That is actually what we will do in this article.
