What Are The Most Popular Tools Used By DevOps Engineers?

The constantly evolving DevOps environment is heightening the quick development and release of IoT solutions to client bases and business infrastructures.  For DevOps Engineers entering the industrial space, it is important to know popular tools implicated in all regions of application development.



Amazon Web Services (AWS) is the industry-leader cloud-computing platform, established in the market for an extensive period.  AWS operates PaaS, IaaS, and SaaS models, offering the greatest range of services across its platform to build and assist project needs than any other Cloud Provider. This enables the deployment of applications as cost-effective, quick, and reliable, making AWS the perfect service to aid project innovation.


Azure is an industry-leading, cloud-computing platform enabling access to computing sources through connection to the Microsoft Cloud Service Provider from an existing Network as a PaaS or IaaS model.  As the most recent Cloud Computing Service, Azure has gained current popularity as an application host due to its cheap set-up, support of multiple script languages, and expanding global access to multiple data centers and services to assist the development of varying project/business needs.



Git is an open-source DevOps tool to track and change code, that follows a Distributed Version Control System (DVCS) which places it as a popular scalable system among large teams.  The key functions of Git are to make the optimisation of software as fast and efficient as possible in all areas of delivery.  Operating in a non-linear environment, Git enables branches to continuously update and input data without interfering with the master branch.  This means software can continuously be elevated, recorded, and backed up without breaking the fundamental code.



As an open-source build automation tool, Gradle can be utilised to develop projects of varying scales and positions due to its flexibility.  The build-scripts are written using Groovy or Kotlin Domain Specific Language (DSL).  As a highly customisable system, Gradle is an easy tool to build applications promptly on code plugin scripts like Java and Python.  Tests can be augmented without rewriting pre-defined tasks, making Gradle performable in developing applications.



Jenkins is an open-source automation server that acts as a Continuous Integration and Development tool (CI/CD), allowing developers and operators to consistently build, test, and deploy code without the barrier of delay.  Jenkins continuous integration automates the test and verification services enabling developers to deliver code through the repository to a CI server that will pass data to test or rebuild.  This means cycles are continuously being relayed to test against the code input at an effective and reliable process.  For DevOps engineers this tool is essential, to release and deploy consistent and validated code to the client faster.

Deploy/ Operate


Docker is an open-source automation tool permitting Developers to build and deploy solutions within lightweight software containers to send an application to be tested without the interference of external barriers like input and output discrepancy in the Linux machine environment.  For this, all parts of an application can be provided under one framework that is easy to design and stack in isolation against other applications ensuring optimal performance and security.


Kubernetes is an open-source automation tool to manage container deployments in a scalable and monitored environment.  The master node operates slave nodes to communicate and execute application processes across container clusters to orchestrate high availability, scalability and back-up restore across containers.



Nagios is an open-source monitoring system, that enables continuous monitoring of system infrastructures to ensure functions are working in all phases including CI/CD pipeline, application, services, and server health.  It is a popular tool to resolve system errors and processes in an automated fashion, safeguarding project infrastructures in a secure, scalable environment.
