5 Common Challenges that DevOps Guidelines Can Address
If you’re a beginner in DevOps project management, you’ll definitely encounter some challenges. However, following DevOps best practices will minimize errors in your development process. Below are some of the common challenges you may encounter.
Multiple Development Stages
Creating a software application using DevOps requires multiple stages and teams. These stages are set up to hasten the development process and lead to a higher quality final product. However, as the app goes through this process its chances of acquiring bugs can be hard to deal with for an inexperienced team.
Moving from Manual Testing to Test Automation
Test automation requires a lot more programming experience than manual testing and might be challenging for DevOps beginners, especially considering how fast-paced a DevOps production cycle moves. The solution is to acquire the proper DevOps training for this type of testing before making the switch.
Switching from Monolith to Microservices
With monolith architecture, all aspects of a code must be completed in a single program. However, with microservices, you can split the functionalities of a code into different units and develop them separately but connected. The challenge here is to make sure not to duplicate functions.
Managing Release Cycles
One difficult part of adopting a DevOps system is the short development cycle. You have to continuously develop, test, deploy, and launch the software. Each adjustment made to the application must then pass through the software release cycle, which can be a challenge if you don’t have an experienced project manager on your team.
Software Application Integration
Integration is a good way to save money and boost your team’s effectiveness, but if the team is inexperienced in microservices, integrating your project might prove to be a challenge.
Top 10 DevOps Best Practices and Guidelines
Adopting DevOps best practices will boost your team’s productivity levels and reduce waste of resources and make your company stronger. The guidelines below will help you make the most of DevOps.
Establish a clear and defined DevOps workflow
DevOps is completely reliant on teamwork. If there is no collaboration between the cross-functional teams, the whole system will fail. To prevent that, create a clear DevOps workflow where each goal is clear and each team understands its tasks.
Coding and revisions must be done transparently so that each code contributor is aware of all developments. Each project must stick to a defined timeline, and for software releases to happen on time, there must also be quick decision-making.

Implement continuous integration and deployment
Continuous integration and deployment are key to DevOps success. Continuous integration makes it easy to manage changes made to a program’s code because the software is constantly updated.
Continuous integration and continuous deployment increase code quality because the new code will be tested for errors before it is integrated and deployed. This leads to shorter product release cycles. Then, once the product is made available to the consumer, customer satisfaction can be measured.
Adopt a customer-centric approach
The whole purpose of DevOps is to reduce inefficiencies in software development and focus on providing a high-quality final product that will benefit the customer.
A customer-centric approach includes shortening the product’s life cycle so that upgrades can be quickly introduced and ensuring that the interface is easy to navigate. You can easily achieve this by implementing continuous monitoring, test automation, and Agile project management.
Adopt Agile project management
Agile project management ensures that the software development process is broken down into smaller successive units and that each unit is tackled by a collaborative team. This approach ensures that the development strategy can be adjusted based on the results of each stage.
Agile is built on a continuous monitoring and continuous release system. This method ensures transparency and collaboration among the project contributors.
Use the right DevOps tools
Each stage of product development requires distinct tools to ensure that goals are being met. To manage your software code changes, you will need to use a version control system. To track bugs and errors in your source code, you should use bug tracking software. At intervals, you will also need to review the code quality and security using a code review tool.
To ensure you aren’t wasting resources, choose cost-effective and easy-to-use tools. You should also choose tools that work in all production environments and can perform more than one function.
Adopt test automation
As your organization’s production capacity increases, manual testing will no longer be possible. You will need to use an automated testing system to ensure your product deliveries are bug-free.
The advantages of test automation are numerous. For one, you’ll be saving money in the long run as you’ll minimize product failure and ensure a faster release process. You’ll also enjoy a more reliable feedback system. When it’s time for a product upgrade, you can easily base a new software model on the existing source code.
Continuously monitor application performance
DevOps is known for producing quality software thanks to continuous monitoring. Continuous monitoring entails automatic code reviews and unit tests to determine the quality and efficiency of codes before they are deployed.
Continuously monitoring product performance benefits everyone involved. Code writers won’t need to spend lots of time trying to reverse issues discovered at a later stage, as they will be able to resolve issues immediately.
By utilizing microservices, you will improve the quality and scalability of the software. Each service product can easily be reviewed and upgraded without disrupting other microservice products within the software.
Using microservices also ensures that each team has the freedom to choose the programming language that best suits the needs of their project without worrying about integration.
Review security of software applications
DevSecOps ensures that security policies are being implemented at each stage of production. This makes it easy to comply with security laws and resolve security conflicts before they escalate and become costly issues. By automating security measures, you improve the chances of market success for your product.
Continuously reviewing the security of the app you’re developing will eliminate cyber security threats. Possible security threats you may encounter include hackers reconfiguring infrastructure code or accessing data from open-source project management platforms.
Implement configuration management
Configuration management involves maintaining a company’s computer infrastructure and software development process.
By adopting infrastructure as code, you can store and manage your infrastructure in the cloud and take advantage of improved system performance and seamless system upgrades. If you don’t use configuration management, your production capacity will be reduced.
