The buzzword in the IT industry right now is "DevOps." DevOps has a collection of processes to bridge the gap between IT teams and software development teams. DevOps is highly sought after because of its capacity to expedite and enhance the accuracy of software development.
Traditional thinking viewed development, testing, and operations as separate disciplines. But DevOps has now led to a strong alliance between these numerous teams. The DevOps methodology strongly emphasises automation in order to improve communication and collaboration between the development, testing, and operations teams.
A DevOps engineer today performs a crucial role for the business using DevOps techniques. He must be well-versed in the DevOps framework, the overarching idea, and the related technology.
DevOps Prerequisites for 2019
1. Understanding of Containers
Programmers may construct programmes and deploy code directly from their laptops using containers, which are virtualized environments. Containers have an extra advantage over the traditional method of hardware virtualization. Containers create virtualized environments that are light and incredibly scalable by effectively virtualizing the operating system rather than the hardware.
Using container orchestration technologies like Kubernetes, infrastructure provisioning may be completely automated on top of containers. Experience with container technology, such as Docker, Kubernetes, Vagrant, etc., must be listed on every DevOps engineer's resume. Containers have changed how applications are shipped and deployed. Containers enable developers to provide code in precisely specified environments.
2. Recognizing the DevOps tools
The DevOps methodology is applied to technologies using a number of tools with different roles, such as configuration management, automation, continuous integration, build, code repository, containerization, etc. To understand how a tool works, a DevOps specialist needs to at least be conversant with one from each area. Learn about DevOps tools.
He should ideally be knowledgeable about every instrument sold today. Ansible, Puppet, and Chef are the main configuration management software players. Vagrant, Kubernetes, and Docker are utilised for container technologies, whereas Jenkins is used for creating CI/CD pipelines. The ELK stack, Nagios, Zabbix, and Splunk are the best logging and monitoring technologies available.
3. Scripting language proficiency
Engineers working in DevOps must be knowledgeable in scripting languages like Java, Perl, and Python. For most DevOps systems to fully automate tasks, some amount of programming is necessary. For instance, the task automation software Ansible uses the Python-based scripting language YAML.
YAML is used to build a comprehensive automation workflow inside of a configuration management platform. It will be simpler to communicate with the development teams and completely understand their source code if you know how to write scripts.
4. Education and Certification in DevOps
One prerequisite for becoming a DevOps engineer is a DevOps certification. Training and certification as a DevOps specialist provide you an edge over rivals in the industry. Having certifications from each set of tools is desirable in an ideal world. for example, selecting a "Puppet Certified Professional" from the configuration management set.
These certifications will cost you between $200 and $600 USD, but it is wise to invest in your personal growth. Even though formal training is normally recommended because it gives you invaluable hands-on experience, these qualifications can be achieved without it.
5. Expertise with Automation Tools
Automation is the foundation of the DevOps system. A DevOps engineer must be able to manage automation at every stage, including development, testing, and deployment. The majority of these automation systems require some amount of programming to be used, thus scripting knowledge is also essential.
DevOps workers must have a strong working understanding of the Infrastructure as a Code (IaC) framework, which automates infrastructure provisioning through configuration.
technology for managing and containerizing containers. His knowledge of tools like Ansible, Puppet, Jenkins, Bamboo, TeamCity, Docker, Vagrant, etc. is also required.
6. Examining
The proper execution of quality assurance and the related testing procedures at all levels is the responsibility of a DevOps specialist. Consequently, it is essential to have a thorough awareness of the various testing solutions on the market before starting with DevOps. Furthermore, it enables him to detect any issues or flaws at any point during the programme distribution procedure.
7. Strong Teamwork and Communication Skills
Two of the most crucial abilities for a DevOps engineer are collaboration and communication. Cooperation and communication skills are necessary for the DevOps career because it is recognised that a DevOps engineer serves as a link between development teams and IT operations. communication skills for containerization and administration. It's also necessary for him to be familiar with tools like Ansible, Puppet, Jenkins, Bamboo, TeamCity, Docker, and Vagrant.
8. Fundamental understanding of Networking
Making cloud environments and containerized apps requires a basic understanding of networking. Networking enables the integration of the edge services that are installed across several containers or virtual machines. For the final software innovations and the related services to be distributed and deployed onto the client's environment, a strong understanding of networking is also required.
9. General understanding of computer science
The IT operations team, testing teams, and software development teams all often communicate with DevOps engineers. As a result, a DevOps engineer needs to have a fundamental understanding of almost all areas of computer science, including as networking, data science, algorithms, and cloud computing. This solid foundational knowledge enables excellent collaboration between DevOps engineers and developers.
10. Reasonable Mindset
On occasion, DevOps engineers will have to act quickly to keep the team functioning. Since DevOps engineers are known for bridging the gap between developers and IT operations, communication and teamwork are crucial. DevOps engineers must therefore always be logical and have good judgement.
Aura and energy must be projected by them throughout discussions and other forms of communication. Management and leadership frequently view the DevOps lead as the go-to person for all production-related issues. DevOps experts must therefore adhere to these norms.
11. Enthusiasm
A DevOps engineer needs to be passionate about what they do. The key to success in any industry is to work with enthusiasm. One it is. It is a crucial DevOps criteria that must always be adhered to.
Conclusion
It's likely that if you're reading this, you at least have a vague concept about pursuing a career in devops. The following is a list of the requirements that can help you get started with DevOps. We hope that this essay has made the conditions for and methods of DevOps more clear.
