DevOps is a buzzword in some recent times and suddenly now a lot of people and organizations are using it on a frequent basis. There is not any single answer for the answer of question about what DevOps is. It is all about notion, experience & understanding of the culture of the organization and how it fits the current era.
What is DevOps?
DevOps is defined as a functional theory which promotes the synergy between the development and operation branch of any organization. It has already reached to a shape! It is a kind of movement that is required to get a change in IT industry. With this, people will get a change that can help them to conclude their wish of great software and it helps in save money.
DevOps is not a technology, any tool or any inventive framework and it is more of an ideology and concept. It is a culture of organization where application lifecycle management is in the center of focus. DevOps is a merging of two words – Development & Operations. Both of the team has different responsibilities in the application release management cycle. It is related to communication, collaboration & feedback between different stakeholders including developers, testers, foundation & configuration team, formation team etc.
Sub Concepts of DevOps
- Continuous Integration: It is more of a culture of integrating application code or source code into the source code storehouse several times a day.
- Continuous Testing: Automated Testing to be more rigid. The tools are integrated in continuous integration behavior by tools.
- Cloud Provisioning: Virtual machines or cloud instance are highly available, flexible and pay per use. It is beneficial to create different types of instances for different environment such as development, testing, staging & production.
- Configuration Management: It is useful to make runtime environment ready in consistent manner across all the environments.
- Continuous Delivery: Continuous Delivery is terms which used in daily use. It can be used when package file is deployment ready into any environment.
Adoption of DevOps
The significance approach towards improving their management programs is referred as DevOps. Carrying out in the enterprise allows specific details about the respective building products. The success story of DevOps makes it a clinching story for the esteemed companies as well as government organizations.
Tools of DevOps
DevOps signifies that there should be more co-ordination and co-operation between the development and the operation teams. This sort of unification allows for better & quality product delivery. The major advantage with these open source tools is that they provide a lot of visibility into the source code and helps in handling transforming market needs.
The most broadly used DevOps tools are as follows:
- Nagios & Icinga: Significantly, this is a prevalent open source tool developed as a fork from the Nagios monitoring application which is also an open source network monitoring tool. This tool has good affectivity as it has high modularity and facilitates to add interfaces and plug-ins to suit the project needs. This is a best in class monitoring tool with high multithread design that is flexible for integrations with plug-ins, modules and third party services. What is the most interesting fact about this tool is that it supports all major configuration management systems. Its scalable fork with high level features providing a great user experience.
- Jenkins: It is an important tool that helps to integrate project changes very easily by quickly finding out the issues. This is a highly useful DevOps tool for automation. Typically, this built in GUI tool has very little maintenance and offers nearly 400 plug-ins to support building and is used to perform testing virtually on any project. It supports the most important DevOps feature of continuous integration and continuous delivery. This is a Java based open source tool which helps in testing by building, testing & integrating software continuously besides monitoring some of externally running jobs. Moreover, it requires little maintenance and easier to build & execute any type of test cases.
- Docker: IT promotes DevOps team to build and run distributed applications and expedite to work collectively. Also it supports flexible image management and has a private registry to store and manage images or configuring image caches. It helps developers as well as admin to send a product or service for delivery without the interceding cross functional environments. It is based on containerization technology and it contributes flexibility to applications by moving them across platforms in self-contained units. It has standardized format and has easy writing test cases in any language virtually. The tool helps in configuration management, scaling & controlling flaws.
- Git: Due to the need of source control management software by Linux community, this open source tool comes into picture. What this tool does is to help in control management and accommodate support to the distributed systems. Some of its feature includes enabling repos, local branching, conducive staging, multiple ventures, and pulling requests among others which makes integration & distribution easy. It is one of the popular DevOps tools and is now widely used across the software industry. Git basically allows keeping track of the development work done. Also you can save different versions of your source code and even return to a previous version as well.
- Ansible: This is one of the configuration management tools which are very similar to other like Puppet & chef. If simplicity is your desired KPI, then Ansible can be a good choice for you. It forms a simple way to automate the entire application lifecycle. It further helps DevOps teams to scale up the automation and speed up the productivity. Also it helps to manage the complex deployments and speeds up the development process.
Now what are the benefits of DevOps and why would anybody use that? Well this has several points for justification.
- The DevOps movement has helped in inspiring the growth of communication skills, quick grasping of domain & a passion along with sensitive for a concealed business.
- DevOps help in standardizing production environment and automating implementation techniques. It has helped people in making predictable implementations and has freed people from regular repetitive jobs.
- DevOps has helped in balancing the balance between stability & adding new features. The integration of test-driven methods, allocated code base, continual unification & automated implementation, by implementing these technique problems in an organization seems to be less complex with this.
