What is DevOps?

In a software company, there are two teams: development and operations. The development team creates new systems, while the operations team tests and implements the products. Sometimes, the operations team provides feedback on bugs, causing delays in the development cycle.

DevOps is about breaking barriers between development and operations teams through collaboration. It’s a popular IT concept that involves software development, operation, and management across a system. DevOps is not just a single tool or method; it’s an approach that enables greater agility in operations. It emphasizes collaboration between developers and manual and automated systems.

How Does DevOps Work?

DevOps unites Development and Operations teams, breaking down traditional silos between them. These teams operated separately in the past and had to invest much time and effort in meetings and emails to stay informed.

Adopting DevOps shifts the focus from departmental goals to organizational goals, fostering collaboration and proactivity. With automated tools and faster processes, teams work closely, identifying and resolving issues swiftly. DevOps prioritizes security and automates and monitors the complete software delivery process, from development to production.

DevOps serves multiple purposes:

Faster launch of new features
Increased customer and developer satisfaction through efficient processes
Feedback loops for better communication

Key DevOps principles include:

Automation
Self-service
Collaboration
Iteration
Continuous improvement
Continuous testing

DevOps Lifecycle

The DevOps lifecycle consists of four main stages represented as an infinity loop. These stages create a feedback loop, allowing organizations to rapidly deliver quality-tested solutions to customers.

1) Design and Plan

The initial stage of the DevOps lifecycle is planning. In this phase, stakeholders from the business, development, and IT teams collaborate to determine the features to include in the upcoming development cycle and assess their value for the business.

2) Continuous Integration

Next is continuous integration, a DevOps approach consisting of three steps: code, build, and test. These steps aim to improve product quality and utilize automation for building it. In this model, code changes are frequently merged into the central repository. An automated tool fetches the code base and tests its quality. After testing, a binary solution is built and functionally tested.

Teams can use manual and automated testing to generate comprehensive reports that benefit the organization.

3) Continuous Deployment

Continuous deployment is another part of the DevOps model that combines the Release and Deploy stages. Any quality-tested build will be automatically released and deployed to pre-production or production environments. The DevOps team can adjust the release and deployment frequency as needed.

4) Continuous Monitoring

Continuous monitoring is the final stage of the DevOps lifecycle, consisting of two parts: Operate and Monitor. It involves overseeing software operations, gathering crucial security and health information, and collaborating with team members to resolve issues swiftly and effectively.

DevOps Benefits

DevOps can make organizations more flexible, enhance teamwork and communication, and speed up the time it takes to launch products or services.

1) Increased Agility

In DevOps, a crucial practice is automating the software development and delivery process. This means using machines to do repetitive tasks like testing code, deploying software, and setting up infrastructure, which people usually do. By doing this, DevOps allows us to handle changes quickly and efficiently.

2) Faster Time to Market

DevOps helps get new code changes, like bug fixes or new features, into production faster. It automates tasks like code testing and deployment and focuses on secure solutions. This makes the development and operations teams quicker and more flexible, provides readily available solutions, and makes businesses more competitive.

3) Enhanced Security

DevOps solutions often include security measures to improve efficiency and results. They call it DevSecOps. This means integrating security into the products and features throughout the development process, not just at the end. By doing this, teams can find and fix security problems early instead of waiting until the end. DevSecOps delivers solutions faster and reduces the cost of making software.

4) Improved Communication and Collaboration

DevOps implementation works by having the Dev and Ops teams communicate and collaborate closely. When they understand each other’s requirements and priorities, they can solve problems quickly and more efficiently.

5) Better Feedback Loop

A feedback loop is like gathering information from different parts of the organization and sharing it with the right teams. These teams can then use the information to improve and deliver the solution faster.

DevOps uses automation and “right-to-left” feedback to make the feedback loop easier. This means that information from later stages of development is sent back to earlier stages automatically. For example, if there’s an error during the build phase, the testing team gets notified immediately to fix it. This way, the DevOps best practices feedback loop makes the process faster and improves the quality of products.

DevOps Model Challenges

Using the DevOps solutions model makes development and releasing things more efficient, but it also comes with challenges.

1) Culture Shift

DevOps needs a cultural shift. It means the Dev and Ops teams must work together, understand shared responsibilities, and collaborate to solve problems. If the teams can’t solve this challenge from the beginning, it will affect the efficiency of the whole development unit and the organization. One way to overcome this is by creating a shared vision through team communication.

2) Adoption of Tools

DevOps uses new tools, so older systems must be replaced with newer ones. This might seem challenging, but training team members to use these modern tools is essential to overcome this obstacle.

It’s not just about using fancy new tools when transitioning to the DevOps best practices culture. Many new tools appear in the market frequently. Instead, focus on getting the tools that suit your business needs best.

3) Establishing Metrics and Processes

Using the DevOps model involves changing how things are done. It can include setting up a CI/CD pipeline or creating automated tests. When following these new processes, you must also choose and track the right DevOps implementation metrics. To do this, you must carefully examine the processes and pick metrics that align with your business goals.

Doing all of these things at once can be a big job. To handle this challenge, you can start small. To tackle it effectively, begin with a small pilot program and a testing framework.

4) Change Management

DevOps needs a culture of always getting better and learning continuously. Organizations should know that processes and tools may change as they move further into DevOps implementation or the product grows. The organization and the DevOps team should be flexible and adapt to the changing needs. To adapt, you need accountability, always trying to get better, and never stop learning.

What is MLOps?

MLOps is a collection of strategies that automate the machine learning process, connecting model creation, development, and operations. It uses DevOps principles with machine learning to prevent issues in your machine learning projects. MLOps solutions are a set of smart ways that mix machine learning and DevOps solutions. It helps quickly put ML models into action and deliver updates to clients faster, just like DevOps best practices for software features.

Why MLOps?

Machine learning (ML) differs from standard software because it revolves around data. The code is designed to handle the data rather than traditional application behavior. ML is an ever-changing system; the real work begins after deploying models. Models must be regularly monitored, updated, and redeployed as data changes to get the best results. MLOps pipeline ensures you get reliable insights faster and in a controlled way, bringing the business focus back to ML operations.

MLOps brings together all teams’ knowledge to make ML more efficient.
It follows MLOps best practices and guidelines to go from ideas to experiments to production-ready models smoothly.
It avoids delays by dividing expertise well.
With the MLOps pipeline, you can train models fast, keep track of experiments, and create powerful APIs for deployment.

How MLOps work?

The MLOps lifecycle or workflow includes these steps:

Extracting Data
Analyzing Data
Preparing Data
Training the Model
Evaluating the Model
Validating the Model
Serving & Monitoring

MLOps can be adopted in three ways:

1) Manual Process

For businesses starting with machine learning DevOps, this process is standard. A manual ML approach can be suitable if you don’t need to change or train your models often.

In this standard data science technique, you experiment and iterate at the beginning of deploying machine learning. Each process step, like data preparation, model training, and testing, is done manually. MLOps tools like Jupyter Notebooks are used to handle data quickly. However, using the manual process increases the risk of model failure in the real world.

2) ML Pipeline Automation

This architecture is excellent for deploying new models using fresh data, not new machine-learning ideas. It automates the ML process, making experiments faster. It enables continuous deployment of model predictions and automates retraining models with new data in production. You must set up ML experiments, automatic data handling, model validation, and metadata management to make it work.

Components must be reusable and shareable to build MLOps pipelines. Exploratory data analysis (EDA) code can be stored in notebooks, but component source code should modularize. This approach is helpful for systems that need to adapt rapidly to changes in clients’ behavior, prices, and other factors. However, if you want to experiment with new ML ideas and deploy them fast, you’ll need a CI/CD infrastructure to automate building, testing, and deploying your ML pipelines.

3) CI/CD Pipeline Automation

This level suits tech-driven businesses that need to retrain and update their models frequently, sometimes even hourly. They deploy these models across thousands of servers simultaneously. For such enterprises, an end-to-end MLOps cycle is essential. At this level, the Data, Machine Learning Model, and Machine Learning Training Pipeline components are created, tested, and deployed automatically, significantly improving from the previous level.

With this approach, data scientists can quickly try new ideas for feature engineering, model design, and hyperparameters. The automated MLOps pipeline has six phases of CI/CD, which allow you to test new machine-learning algorithms and models repeatedly. You can orchestrate the experiment phases. The source code for the ML pipeline stages is produced and then saved in a source repository.
