Types of DevOps Engineers
There are two types of DevOps engineers – one who works on infrastructure and another who works on application development. The first type of DevOps engineer is responsible for managing the entire infrastructure including servers, networks, storage systems, etc. They also work on automating processes and improving efficiency by using various technologies like cloud computing, virtualization, containers, microservices, continuous integration/continuous delivery (CI/CD), etc.
The second type of DevOps engineer focuses more on developing applications. They use different programming languages such as Java, Perl, C#, Ruby, JavaScript, Go, PHP, Python, etc. to develop web or mobile apps.
What does a DevOps engineer do?
As mentioned earlier, a DevOps engineer is responsible for managing the entire infrastructure. This includes everything related to servers, networking, storage, databases, operating system, etc.
These professionals have to plan and implement the complete infrastructure before they start working on any new projects. They need to ensure that the existing infrastructure is scalable and can handle future workloads.
In addition, these professionals should be able to automate their tasks so that it becomes easier for them to perform repetitive tasks. For example, if there is an automated task to deploy code to a production server, then it will save time and effort for the developer.
Another important aspect of a DevOps engineer is to improve the performance of the existing infrastructure. These professionals should be able to monitor the performance of the infrastructure and take action when required. Experts at FITA Academy will help you gain relevant skills to develop your carrer in DevOps.

DevOps Engineer Roles & Responsibilities
Automation- Automation is a critical part of any DevOps strategy. It helps ensure that your team can scale up or down without having to worry about downtime. The goal here is to automate everything from deployment scripts to build processes so that your team can spend their time focusing on higher-level tasks instead of mundane operational tasks.
Configuration Management- Configuration management ensures that all of your applications are deployed correctly and that they run smoothly. It also makes sure that each application has access to the same configuration data. For example, if you’re running multiple instances of a web server, then you need to make sure that these servers share the same set of configurations.
Continuous Integration/Continuous Delivery- Continuous integration means that every change made by your team gets automatically tested before it goes live. If something does go wrong, then you’ll know immediately. You can do this using tools like Jenkins, Travis CI, CircleCI, and AppVeyor.
Continuous delivery means that once you’ve successfully tested a new release, you can push it out to production without waiting for someone to manually approve it first. Tools like GitLab, BitBucket Pipelines, and Azure Pipelines help you manage deployments.
Monitoring- Monitoring allows you to track performance metrics such as response times, uptime, and errors. It also gives you visibility into which parts of your infrastructure are under stress and where bottlenecks might exist.
Security- Security is an important aspect of any modern software system. Ensuring that your network is secure is vital because hackers will always try to find ways around security measures. A good DevOps engineer should have experience in securing networks and systems.
Software Development Lifecycle (SDLC)- Software development life cycle refers to the process of developing software. It includes activities such as requirements gathering, design, coding, testing, and maintenance.
Version Control- Version control is a way of tracking changes to source code over time. There are many different types of version control available, including Subversion, Git, Mercurial, Perforce, and CVS.
Virtualization- Virtualization lets you create virtual machines that act just like physical ones. They allow you to test new features before deploying them to real hardware. Some examples of virtualization technologies include VMware vSphere, Microsoft Hyper-V, Oracle VM Server, and OpenStack Swift.
Web Application Firewall (WAF)- Web application firewalls protect websites from malicious attacks. They typically monitor requests coming into a website and block suspicious activity. WAFs can be implemented at both the frontend and backend.
Workload Balancing- Workload balancing is used to distribute incoming traffic across multiple servers. This is done to prevent one server from getting overloaded while other servers remain idle.
Docker- Docker is an open platform for developers and sysadmins to easily deploy and run distributed applications. Docker containers provide a lightweight virtual machine that runs only the required pieces of an application.
API Gateway- API gateways let you expose APIs to external clients. They perform authentication, rate limiting, and caching on behalf of your services.
Load Testing- Load testing simulates high volumes of users or devices to see how well your service handles peak loads. Load tests can simulate anything from a single user to thousands of simultaneous users.
Cloud Computing- Cloud Computing provides flexible, scalable, and pay-as-you-go resources. You can use these resources to build and host web apps, mobile apps, databases, and more.
CD Pipeline- A pipeline is a series of steps that are performed automatically when building or releasing software. The purpose of a pipeline is to ensure quality by providing consistency throughout the release process.
Infrastructure As Code (IaC)- Infrastructure as code is a practice where infrastructure management tasks are automated using scripts. IaC makes managing infrastructure easier because there is no longer any guesswork involved with configuring servers and networks.
DevOps Lifecycle
DevOps is a term that describes how IT departments are working towards better collaboration between development teams and operations teams. This involves breaking down barriers between the two groups and making it easier for developers to deploy code quickly while ensuring that changes don’t break anything else.
A DevOps lifecycle is now widely accepted as being essential to achieving success in today’s digital world, and there are a number of key steps involved in creating one. These include:
- Define what you want to achieve
- Build a plan
- Implement the plan
- Monitor and measure
- Improve and repeat
This can be implemented by using the best practices from several technologies which can learnt from DevOps Online Training will help in developing and implementing a DevOps life cycle.
