Evaluate, design, and analyze the automation systems and Scripts. Solving the complex Resolution issues by applying the best cloud security solutions services, are some of the days to day works of a DevOps Engineer. Below is the process that how a DevOps Engineer handles a project in his team.
1.DevOps Engineer:
A DevOps Engineer has to read the Articles, that constantly released by some websites like AWS. He has to keep up to date, what is going on in the tech world. Because we have new applications and tools, that Releasing daily. If you are not aware of them, you do not use them and apply them, and finally, you cannot show the output in your DevOps Environment.
As Microsoft, Google, and AWS are releasing new services, this becomes the exact test, for DevOps Engineers. During CI (continuous Integration), these engineers have to make many scripts for automation and manual process. They should have a good thought of Infrastructure, in General like Google, Azure, AWS is important.
The elements of this are all signs the same, mastering the way, how networking and Bridging works are implemented. Knowing about IP ranges and the DNS records is all useful. They have to understand a few databases.
2.Test Automation:
When it comes to testing automation, a DevOps Engineer has to do Repeated tasks, that validate our systems whether it is working or not. We can call it a unit test.
3.Transformation:
All of us forget that DevOps is a set of tools, but a manager's mindset may change. You will push back by many people. A manager may not think, why we must invest in flexibility. Why a Database administrator can not understand, why you must deal with production schema access, your colleagues may not understand why you have to go on a call. Changing from Dev to DevOps is only a mental mindset.
4.Security:
As the Project Duty of the DevOps engineer, we plug in certain things like security vulnerability scans. We have to monitor in one place, which detects an abnormal use. Installing the Antivirus shields, across all security attacks. We must do threat modeling for our systems, to check whether a potential weakness is a true or a lie.
5.Reliability:
To make a system more reliable, we have to measure it on demand. We must design services, that they expect to be fixed. This process is applied to certain things known as circuit breakers and retries.
6. Observability:
I think you dint heard of the term observability, but when you see into the work of the DevOps engineer, we have heard certain things like logging, metrics, and monitoring. But we must consider that every idea is smaller and bigger. Observability is the capability to ask, questions to your software and get answers when you don’t know what are the questions are. When you move, it is the thing of making a system to offer you results into that what is happening.
Without observability, there is no scope for doing Ops and DevOps. This is the main application, that shows us the capacity to modify our system after it has been moved to production. The Tools of observability accept our requests counts. These tools set some alerts when they terminate our service level complete objectives. If there is no observability there is no real hard thing to design our systems.

7. DevOps Engineer Road Map:
I have shown small Ingredients that what a DevOps Engineer does, I want to say you that, you don’t need to know all of them. If you are already in DevOps, you can learn other concepts than these. If just started learning DevOps, pick anyone and upgrade yourself on it.
DevOps engineer skills
A certified DevOps engineer has to acquire certain skills to perform his duties well. In this section, we will look into the various skills and knowledge that a DevOps engineer should have.
Basics of Linux and scripting
Today most companies prefer to host their apps on Linux OS. So a DevOps engineer has to gain knowledge of handling Linux OS which is crucial in this regard.
In addition to this, they have to acquaint themselves with the configuration management tools such as Puppet, Chef, Ansible, etc. Most of their master nodes run with Linux OS. Hence, DevOps is an automation concept that includes an automation process for infrastructure provisioning services. Also, they must have to gain skills in any coding language like Python. This will be useful for handling Linux and Linux-based scripts easily for them.
Knowledge of different DevOps tools
There are different stages where the DevOps practices are performed and at each stage, certain tools help to proceed. These stages are as follows:-
Source code management
The duty of a developer lies in the development and modification of the software codes regularly. Here, the source code management includes the storage of code, merging the old cold with a new one, controlling the code versions, etc. Moreover, tools like Git, GitLab, etc are useful in this regard.
Configuration management
This section deals with the management of software and OS setup that needs to keep tracking. Also, it is done through a single click of a button or by giving a command on a server. This facilitates managing large configurations across loads of servers. Besides, there are certain tools like Puppet, Chef, and Ansible that are useful in config. management.
Continuous Integration (CI)
CI is the automation process of integrating code from different contributors and developers to a single software project. Besides, this is a primary DevOps best practice. It allows developers to regularly merge code changes. The tools that support CI are Jenkins and Bamboo.
Continuous Monitoring
This practice is useful to regularly monitor app performance, error logs, failures, etc. Moreover, tools that support regular monitoring practice are Nagios, Splunk, etc.
Continuous Testing
This is the practice or process of minimizing the feedback time after the code testings executed. Hence, the code is tested through automation testing tools within the development environment. The tools that support continuous automation testing are Selenium, TestComplete, etc.
CI/CD
This is the practice of continuous integration of code from various developers, testing them, and deploying code successfully to production. Again the deployment of codes to production needs to spin up new containers through automated scripts.
Containerization
This is a process of virtualizing an OS so that different containers running several apps easily share the OS and system resources. Besides, the tools that support this process are Docker, Kubernetes, and Vagrant which are top containerization providers.
Soft Skills
In the IT industry communication plays a great role for which Soft skills are very important. DevOps professionals should have the soft skills for good communication with the team members. Today most companies prefer Agile workspace using DevOps methodologies. They used to work at high volumes and with high velocity that requires soft skills. This is needed to quickly contact team members for sharing valuable and meaningful info.
Moreover, a certified DevOps engineer should have knowledge of key concepts of DevOps. Companies can tailor the framework as per their need as they are flexible to modify. Besides, DevOps’s main role is to bring the development and ops teams together to bridge the gap and work faster. The ultimate goal of this practice is to deliver the right software product on time without any delay.
