海外TECH	DEV Community	Introduction to DevOps and the top 10 tools used in DevOps Methodology.	https://dev.to/grayhat/popular-10-tools-used-in-devops-methodology-34hj	Introduction to DevOps and the top tools used in DevOps Methodology The word DevOps is a combination of the terms development and operations meant to represent a collaborative or shared approach to the tasks performed by a company s application development and IT operations teams In its broadest meaning DevOps is a philosophy that promotes better communication and collaboration between these teams and others in an organization In its most narrow interpretation DevOps describes the adoption of iterative software development automation and programmable infrastructure deployment and maintenance The term DevOps also covers culture changes such as building trust and cohesion between developers and systems administrators and aligning technological projects to business requirements DevOps can change the software delivery chain services job roles IT tools and best practices While DevOps is not a technology DevOps environments generally have common methodologies These include the following Continuous integration and continuous delivery or continuous deployment CI CD tools with an emphasis on task automation Products that support DevOps adoption including real time monitoring and incident management systems configuration management and collaboration platforms andcloud computing microservices and containers implemented concurrently with DevOps methodologies A DevOps approach is one of many techniques used to execute IT projects that meet business needs DevOps can coexist with Agile software development IT service management frameworks such as ITIL project management directives such as Lean and Six Sigma and other strategies Benefits of DevOps a DevOps takes down the traditional departmental style in which a certain team is assigned to each mission and it used to be siloed in effect This in turn has reduced versatility and reactivity DevOps encouraged cooperation and collaboration beyond the lines of an organizational hierarchyb When companies implement DevOps with fault detection techniques it contributes to dramatically reducing failures DevOps is commonly implemented on top of the Agile model it facilitates teamwork modular programming etc making it easy to identify faultsc Organizations would become more performance based than power based with DevOps This makes the workforce more innovative and productive and decreases attrition and increases retentiond In DevOps teams develop a culture of confidence and teamwork that supports them by constantly working on creativity and innovation to enhance organizational products and services Such initiatives allow businesses to understand better and address their consumer needs Below are the most common top tools used in DevOps Methodology ELK Stack ELK is known as Elastic Search Logstash and Kibana three powerful open source tools mainly used in Continuous Monitoring Ansible Ansible is an open source platform that offers one of the easiest ways to automate the IT infrastructure and applications such as network setup cloud deployment and development environment design Chef Chef is a powerful automation tool for configuration management that allows you to convert infrastructure into code Docker A lightweight tool that uses containers to bundle an application before shipping the entire container as one package with all the specifications and dependencies Jenkins Jenkins is a Java written continuous integration server You can use it in near real time for testing and monitoring changes As a developer this will help you easily identify and fix bugs in your code and automate their development testing Splunk Splunk is a software platform for searching analyzing and visualizing machine generated data or logs collected from websites apps sensors computers etc that make up the IT and business infrastructure Nagios Nagios allows you and your organization to recognize and solve IT infrastructure problems before they affect key business processes Puppet Using an open source configuration management framework to simplify the way your software is inspected distributed and managed over the entire life cycle with device independence Git GIT is a version control system that allows you to monitor changes to your file and easily organize your team s work by using it Selenium Selenium for web applications is a compact software testing platform It gives you a simple interface for the creation of automated tests Next in this DevOps tutorial post let s look at a few case studies Real time Use Cases of DevOps by NASA Problem Statement For greater agility and cost savings NASA had to shift almost applications from a conventional hardware based data center to a cloud based environment Managing multiple virtual private clouds VPC s AWS accounts were Burdensome Solution By using Ansible Tower to control and schedule the cloud climate this issue was solved Impact Stacking applications from hours to less than minutes per stack Real time disk and RAM monitoring was achieved The time required to update nasa gov has been reduced from hour to minutes I hope you enjoyed and learnt something new please feel free to like and leave a comment or feed back in the comment section
