Cisco DevOps: Essentials, Trends, & 300-910 Exam Guide

Cisco DevOps - Essentials, Trends, & 300-910 Exam Guide

From the beginning, software development was split into two separate groups. Within the Cisco DevOps, this narrative begins to change. The development team plans, designs, and builds the system. After that, the operations team tries to put what the developers made into action. The operations team tells the development team about any bugs that need to be fixed and any work that needs to be redone.

This article covers the essentials of Cisco DevOps, including its defining principles and a glimpse into success stories. We will also cover the journey towards DevOps certification, with a focus on the 300-910 DEVOPS certification.

What is DevOps?

What is DevOps

We refer to this as the DevOps strategy. The infinity sign-like graphic implies an ongoing process of increasing productivity and never-ending activity. Thanks to the DevOps methodology, companies can better adjust to updates and changes in development. Teams can now produce more quickly, and deployments go more smoothly and consistently. DevOps facilitates a successful software development process by managing a smooth team flow despite potential communication obstacles.

Principles of DevOps

Principles of DevOps

DevOps is built on three fundamental principles.

  1. Automation: It simplifies repetitive tasks to save time and reduce errors.
  2. Collaboration: Developing a culture of open communication and shared responsibility.
  3. Continuous integration and deployment: Ensuring a smooth and continuous delivery pipeline.

There are also three ways to guide DevOps practices.

  1. The flow of work is about optimizing the process from development to operations.
  2. The feedback loop establishes a feedback loop for constant improvement.
  3. Create a place that encourages trying new things and learning from mistakes. This means we always look for better ways to do things and don’t worry about failing sometimes.

DevOps Success Stories: Netflix and More

Nowadays, DevOps is everywhere. It is more about teamwork and collaboration than just using tools, and many tech giants and organizations have chosen This approach.

Companies like Amazon, Netflix, Walmart, Facebook, and Adobe have all turned to DevOps to simplify their operations and allow new ideas. Netflix, in particular, has been a pioneer in this space since launching its streaming service in 2007. By 2014, the stakes were high, with potential losses of $200,000 for every hour of downtime. DevOps practices have been crucial in helping Netflix address these challenges.

Netflix developed a strategy known as “chaos engineering” by introducing the Simian Army, a set of tools designed to intentionally cause issues in their systems. This was to test and improve the resilience of their network. Among these tools was Chaos Monkey, which randomly shuts down instances to assess the system’s ability to recover from such incidents. This approach has enabled Netflix to maintain the high availability and reliability of its services, even in the face of unforeseen disruptions, showcasing the power of a well-implemented DevOps culture.

Today, more and more companies are leaning towards automation to reduce their delivery times and the gap between their development and operations teams.

Phases of DevOps

Different tools develop the DevOps culture in different phases. Let’s examine these phases.

In the first phase, planning, the development team creates a strategy that considers the customer’s application goals.

As soon as the team creates the plan, coding begins. The development team works together on the code. Using tools like Git, they store multiple versions of the code in a repository and merge them when necessary. This process is known as version control. In the build stage, tools like Maven and Gradle run the code. After a successful build, the team checks the code for flaws and issues. For automated testing, Selenium is the most popular tool.

The code can be deployed after passing a number of automated and manual tests. The operations team has received it and is currently deploying the code to the workspace. The most popular tools for automating these stages are Ansible, Docker, and Kubernetes. Following deployment, the product is watched over constantly. One of the best tools for automating this stage is Nagios.

The planning phase receives the feedback, which forms the DevOps lifecycle: the integration phase. Jenkins, a program, transmits the code for testing and building. When the code successfully passes the test, it triggers continuous integration, the process of sending code for deployment.

DevOps Growth: From Trend to Essential IT Strategy

DevOps Process

In the past ten years, DevOps has grown a lot. A special trend at first, DevOps has now become a big deal, with many businesses adopting it. At first, only a few people tried it out, but now a huge group of people use it, know a lot about it, sell tools for it, and give advice on it. DevOps now sets the standard in IT management, covering everything from running computers and developing software to providing security.

The DevOps market has grown exponentially in recent years. According to an extensive report on DevOps in 2024, the value of the DevOps market is expected to go up from $10.56 billion in 2023 to $12.8 billion in 2024. This is a growth of 21.2% in just one year. This growth is because more people want DevOps for its ability to handle big projects easily. It’s getting more recognized, and there are better ways to do things now. Also, the DevOps tools are improving, and there’s a bigger need to make and deliver updates quickly.

Cisco recently surveyed Cisco Live events in Melbourne and Amsterdam. The purpose of the survey was to find out how many people are using DevOps and to point out which DevOps tools work well. The survey included only participants who regularly use DevOps tools daily.

Questions That Were Asked in the Survey

The first question was, “How would you describe your organization’s adoption of DevOps practices?”

  • 78% of people said DevOps is kind of in place at their work.
  • 13% said their place is just beginning to use DevOps.
  • 9% shared that DevOps is completely set up where they work.

The second question in the survey was, “What is the biggest challenge you’ve encountered while implementing DevOps?” 30% selected the top two challenges: 

  • Difficulty coordinating across teams
  • Resistance to change. 

Following that was a lack of skilled staff, a limited budget, and enormous technical debt. 

The next question was, “What additional features or improvements would you like to see in Cisco’s DevOps-related products or services?”

  • 48% of people said that they want more training and help.
  • 35% said they’d like it to work better with other tools they use.
  • The numbers decrease to less than 10%, with nobody unhappy.

The fourth question was, “Are there any specific DevOps tools or strategies that have significantly improved your development processes?” Ansible was the most popular, with twice as many responses. Next in line were Terraform, Python, Jenkins, GitLab, and GitHub. Each of these got about the same number of votes from people.

The fifth and final question in the survey was, “How do you see the role of AI and machine learning in the future of DevOps?”

  • 52% responded that it is essential and will be heavily integrated.
  • 43% responded that it would be helpful but not critical.
  • Only 4% responded that it wouldn’t be essential, and no one thought it would be completely irrelevant.

The Future of DevOps

The DevOps market is poised for significant growth in the coming years, projected to reach $29.79 billion by 2028, growing at 23.5%. This growth is anticipated due to a focus on developer experience, maturity of continuous integration and delivery, collaboration amongst DevOps teams, multi-cloud and hybrid cloud strategies, and increased emphasis on observability. Key trends in this period include:

  • Using no-code and low-code DevOps tools.
  • Shift Right testing.
  • Adopting site reliability engineering.
  • Event-driven architectures.
  • The maturation of DevOps toolchains.

Cloud adoption and scalability are expected to drive DevOps market growth because cloud environments offer the necessary resources and flexibility to effectively implement CI-CD pipelines. With the advancement of technology, there’s been a significant increase in interest in the DevOps market. Companies are incorporating technologies like machine learning and artificial intelligence to provide cost-effective and operationally beneficial products in the DevOps sphere.
