How and Why You Should Start Automating DevOps
DevOps is not new. Every business in the IT world knows it is the right software development methodology. Indeed, DevOps has enticed the world with its promise of high-quality product delivery at a faster pace. Despite the clear promise of DevOps, many businesses are failing to realize its complete potential. While cultural inertia and skillset sparsity are some of the reasons, the inability to completely automate the DevOps lifecycle remains the greatest impediment for businesses to drive full value from their DevOps investments. Integration of DevOps and automation is what leads to a more efficient software development lifecycle (SDLC). So, let's understand what it is all about automating DevOps and how you can start automating your DevOps processes:
What is DevOps automation?
Automation is the fundamental principle of DevOps. In fact, "automating everything" is the ultimate objective of the DevOps methodology. So, DevOps automation is the process of automating nearly every repetitive and manual task across the DevOps SDLC, from design and development to deployment and release management.
Generally, software development involves many tasks handled by various teams, such as code analysis and unit testing by development teams; functional, performance, and other testing processes by testing teams; and stage-wise deployment and release management by operations teams. DevOps automation tries to automate and streamline all these tasks with no human intervention by leveraging various automation tools or technologies.
Some of the process automation technologies that can be used in the DevOps ecosystem are IT automation and infrastructure automation. On the other hand, Puppet, Chef, Ansible, and Jenkins are some of the popular automation tools leveraged for DevOps automation.
Top 5 business benefits of automating DevOps
Automation is imperative to achieve the DevOps promise of delivering high-quality products at a faster pace. Automation in DevOps makes software development processes simpler, faster, and more efficient, empowering Dev and Ops teams to build, test, deploy, and maintain code faster and with higher quality compared to manual practices.
DevOps automation offers numerous business benefits, here are the top 5:
DevOps automation business benefits
1. Enhanced Productivity
As almost all the DevOps tasks like code integration and application deployment are automated, it certainly results in faster software releases, increased time-to-market, and higher productivity. With automation, there is no delay in processes, as in the case of manual processes. Moreover, as human intervention is almost reduced to zero with the use of automation tools, the developers and operations team can now focus on business-critical tasks instead of wasting time on repetitive, low-priority tasks.
2. High Standardization
DevOps automation enables the standardization of DevOps workflows, processes, technologies, and metrics. This, in turn, helps minimize duplications, reduce risks, and provide proper guidelines. Leveraging standardized practices also provides the scope for automating other manual processes, helping your DevOps ecosystem to move from automation to orchestration.
3. Increased Flexibility
Automating DevOps provides your DevOps teams with greater flexibility in terms of both scope and functionality of the automated process. So, they can now configure and enhance the processes even after changing the tech stack.
4. High Scalability
DevOps automation provides the ability to easily scale the processes as required by simply creating additional processes to meet the increased requirements. Conversely, in a manual environment, any scaling is a challenge, as it is completely constrained by the availability of the team. However, with automation, scaling only depends on the availability of underlying software or hardware, which is not an issue in the cloud where resources are automatically scaled as per the workloads.
5. High Consistency
As the DevOps processes are highly automated, the end results are highly consistent and predictable. Courtesy of the underlying software automation tool that consistently does the same thing until it is reconfigured to do the otherwise. The same is not true for manual processes, where human intervention potentially leads to errors.
Guidelines to consider before automating DevOps
There is no concrete rule book for DevOps automation. The path to automating DevOps is ever-changing. So, there’s a significant scope that you may get caught up in the crosshairs of many questions such as where to get started or which processes can and should be automated when you try to automate DevOps.
Before we look into the DevOps automation best practices, let's dive deep into some common guidelines to help you decide what and how you automate:
1. Prefer open standards
Implement DevOps automation tooling that follows common, open standards and procedures. So, whenever your team or contributors change, you can simplify onboarding and save time on specialized training, without any need to change your tooling. Moreover, as DevOps and deployments are moving to the cloud, community-driven standards for packaging, configuration, runtime, networking, and storage can also be preferred.
2. Leverage dynamic variables
Using reusable code helps you significantly decrease the amount of rework and duplication you need to do now and also in the future. Leveraging externally-defined variables in your scripts or specialized automation tools is the optimal way to apply automation to various environments without any need to change the code itself.
3. Use flexible tooling
Flexible tooling helps you adapt to the changing DevOps ecosystem. Finding a one-size-fits-all tool is not possible always, but using DevOps tools that facilitate flexibility to change technologies helps in reducing rework when you change your objectives or direction. Select a solution that has a wide range of partner integrations that work with any cloud, so you’ll be able to reach your objectives without being constrained by your toolchain.
4. Rely on AI
Leverage data-driven AI algorithms to identify specific patterns within DevOps processes and deal with bottlenecks and challenges. AI-driven DevOps tools can make your work easy when it comes to monitoring development and production.
5. Unify DevOps toolchain
DevOps toolchain fragmentation and pipeline diversity hamper visibility across the software development lifecycle. High fragmentation across the tools makes it challenging to centrally manage and optimize the performance of the DevOps automation toolchain in real time. So, it's imperative to unify the visibility of the DevOps lifecycle to measure, benchmark, and improve software delivery and deployment.
DevOps automation best practices
As we have curated all the guidelines you need to get started with DevOps automation, now is the time to know the best practices you need to adopt to leverage the full potential of automation. Here are some of the DevOps automation best practices:
Continuous integration, continuous delivery, and continuous deployment (CI/CD) go hand in hand with DevOps. The DevOps methodologies, along with the CI/CD pipeline, improve your developer productivity. Though CI/CD and DevOps are not the same, CI/CD is still the key aspect of DevOps automation. So, CI/CD is the first element you need to automate. You can integrate automation across all the aspects of CI/CD, including code commits, builds, and deploying packaged applications in testing or production environments. This helps in agile monitoring, integrations, and testing to deliver and deploy changes to the application faster while maintaining high quality. Moreover, automating CI/CD frees your team from mundane tasks and allows them to focus on learning new things and adding value.
2. Version controlling
Version control, also known as source control, is an important element of any DevOps strategy, helping teams to manage and track the changes made in the code across the software development lifecycle. Details such as when the changes were made, what the changes were, who made them, and why the changes were made will be tracked, preventing concurrent work from conflicting. So, automating version control takes the above-mentioned benefits to the next level. Moreover, version control automation saves time and produces consistent results.
3. Change controlling
In addition to maintaining your code’s version history, implementing a defined process to roll out application changes helps in scheduling and deploying a change with minimal impact on existing customers. It also helps in maintaining product direction, while reducing the scope of harmful changes to your code.
One of the crucial aspects of change management is defining how a change should be assessed, accepted, and tracked. New change requests must be prioritized as per the existing backlog of scheduled work.
By implementing automation into the DevOps ecosystem, the change management process can be optimized. Automated quality control elements such as test runs and monitoring alerts can help your team assess the basic health of changes without extensive manual testing.
4. Configuration management
To maintain your systems in the optimal state, you must configure the operational systems, software requirements, package dependencies, and system files. However, the traditional process of handling configuration management manually or with custom scripting can be complex and expensive. Through automation, configuration management can provision a new server within minutes with less room for manual errors. The automation also helps you in maintaining the server in the desired state, such as a standard operating environment, without the need for provisioning scripts.
5. Infrastructure as code (IaC)
Embrace Infrastructure as code as it enables you to provision, configure, and maintain infrastructure components such as network components, and virtual machines by leveraging pre-defined code. The software-defined approach helps you automatically define, test, and deploy new infrastructure with new configurations when changes are introduced. This helps you avoid manual errors while saving time and money.
6. Continuous monitoring
Continuous monitoring helps glean operational insights by monitoring the performance and stability of applications and infrastructure throughout the software lifecycle. So, by choosing the right monitoring tools that automatically interpret the raw data and provide correlated insights and actionable intelligence. Automation also enables you to create automated monitoring rules and generate alerts to keep track of infrastructure availability, application performance, and security issues, among others.
7. Log management
Logs facilitate large amounts of data about critical business components. Application logs, infrastructure logs, and audit logs provide insightful data that helps in identifying issues and tweaking code and infrastructure configurations for improved performance. Through automation, you can easily aggregate and analyze these logs and easily identify errors, monitoring activities, and performance metrics.
