The DevOps approach focuses on the primary aspects of collaboration, communication, and integration between the software development (Dev) and IT (Ops) processes. By implementing DevOps principles into the SDLC, enterprises streamline and accelerate their building, testing, deployment, integration, and maintenance of their software solutions, making dynamic innovation accessible and easily practicable. Overall, DevOps implementation accelerates delivery cycles, drives operational efficiency, and results in rapid bug resolutions.
That said, DevOps processes are built on the following core principles:
- Seamless collaboration and communication between development and IT: DevOps foster a collaborative culture between software development and IT teams, breaking down silos, increasing transparency, and resulting in faster and efficient product releases.
- Continuous integration (CI) approach: While developers push code changes multiple times during a day to a shared repository, the CI approach in SDLC automatically triggers a build that compiles it and runs automated tests to ensure that the code changes doesn’t hamper any existing functionalities.
- Continuous deployment (CD) approach: An extension to the CI approach, continuous deployment (CD) protocols involve automatically deploying the code in the staging or production-like environment for further testing. The team performs user acceptance testing, load testing, integration testing, etc. to ensure that the code is always in a releasable stage. Once the code passes all tests, it is then ready for the production environment.
- Automation: To minimize human-made errors during the software development process and make the entire process fast and cost-efficient, software automation plays a crucial role. Automation in DevOps implementation involves eliminating the manual and repetitive tasks, empowering teams to focus on more ROI-driven activities. You can choose the processes you wish to automate across the entire software development, testing, integrating, deployment, and maintenance processes.
- Continuous monitoring & feedback: DevOps implementation results in continuous monitoring and improvement of software solutions to detect and fix performance issues and bugs. The DevOps team can continuously analyze system health, user behavior, and response times to deliver innovation at scale.
- Infrastructure as Code (IaC): IaC is a practice that involves versioning your infrastructure configurations and storing them as code. This makes it easy for DevOps teams to manage, replicate, and scale environments while reducing configuration errors.
Why does DevOps matter?
Although DevOps adoption is on a rise by enterprises looking to deliver software products faster into the market and innovate at a pace their business demands, it becomes challenging to identify where to start while implementing the right DevOps tools for version control, CI/CD, test automation, code validation, etc. Coupled with the massive information and array of tools available in the market, organizations struggle to discern where they need to implement DevOps across their SDLC and what objectives they’re willing to achieve with it.
As per a research from Google’s DORA (DevOps Research and Assessment), organizations can be categorized as high, medium, low, and elite based on their software delivery performance metric benchmarks of deployment frequency, lead time for changes, time to restore service, and change failure rate. Here is what these benchmarks mean:
- Deployment frequency: This defines the frequency at which your organization deploys code to production or releases it for the end-users. An elite performer deploys multiple times a day while a low performer does so once in six months.
- Lead time for changes: This defines the duration an organization takes to go from code committed to code successfully running in production. An elite performer takes less than one hour while a low performer takes over six months to achieve it.
- Time to restore service: This defines the time it takes to restore service when a service outage, defect, or incident occurs, severely impacting user experience. An elite performer takes less than one hour while a low performer takes more than six months to restore services.
- Change failure rate: This defines the percentage of changes deployed to production or end users that results in degraded services thus requiring immediate remediation. An elite performer change failure rate is between 0-15% while a low performer’s is between 16-30%.
While the first two metrics determine your DevOps throughout, the remaining two benchmarks define the stability of your DevOps implementation.
While we discuss these metrics, a pressing question that arises is, why the need to know these and how does it align with my DevOps implementation or strategy?
Across industrial verticals ranging from BFSI to retail & eCommerce, logistics & transportation, and so on, DevOps implementation plays a crucial role to differentiate their operations from the competition and rapidly deliver agile and user-driven solutions with fewer errors. The matter of fact is that disruption and innovation is a constant in today’s landscape. There will always be competitors trying to best you, or consumers looking for more engaging and easy solutions, and technologies changing the game. The focus for enterprises should now be implementing the right tools and technologies to speed up application development and enhance business value at reduced costs and time-to-market.
And this is where DevOps implementation and best practices can help you master agile development with iterative design.
What challenges do enterprises face throughout SDLC & how does OutSystems DevOps implementation help?
In today’s competitive ecosystem, building an enterprise-grade software application is a complex undertaking. What’s more complex is developing a software solution that is of high-quality, delivers superior experiences, and allows innovation at scale.
As enterprises commence their DevOps implementation, they might face challenges such as loosely coupled architecture, a complex combination of several tools and products for effective DevOps implementation, and so on, which eventually impacts their software delivery performance metrics and maturity level. As businesses try to navigate through these dynamic requirements, OutSystems high-performance low-code platform presents opportunities and solutions to all the bottlenecks and challenges faced by organizations during DevOps implementation.
#1: Complex and monolithic applications solved by a loosely coupled architecture
Challenge: Most legacy architectures are formed by large and complex components tightly integrated with each other, making it challenging to test, deploy, or scale individual modules independently. This slows down the release of new features or updates, as the entire architecture needs to be deployed. Moreover, a failure in any one component results in a cascading ripple effect across all components, resulting in service outage or disruption. Overall, tightly coupled architectures result in higher friction between development and operation teams due to conflicting priorities and objectives.
Solution: With software architecture being an imperative predictor for achieving continuous delivery, loosely coupled architecture where components and modules are developed and deployed independently offer more room for innovation, scalability, and competitiveness. It allows organizations to build, test, deploy, and scale entire applications or parts of it fast, thus promoting software agility and resilience. With OutSystems DevOps practices, enterprises can focus on iterative development, launching different modules at different times, ensuring continuous software delivery.
#2: Long release cycles and integration challenges solved by trunk-based development
Challenge: When integrating systems, enterprises often face challenges in merging back the feature/component branch to the main codebase or trunk of the repository, especially for large or legacy modules. This also extends the release cycles as components first need to be accumulated at the branches before integrating with the version control repository.
Solution: Trunk-based development helps enterprises to counter challenges around complex integration, long release cycles, risky deployments, delayed feedback and inefficient release management. It empowers enterprises to run smaller and manageable code merges without impacting any ongoing development, reducing release cycles duration and time-to-market. OutSystems’ DevOps capabilities provides the same codebase for multiple touchpoints, pre-built APIs, UI’s versioning, and feature toggle library, making the implementation and deployment of modules easier and at scale. With OutSystems trunk-based development, organizations can successfully implement DevOps and build a culture of collaboration, agility, and rapid delivery of high-quality applications.
#3: Security, compliance and regulatory challenges solved by shift-left on security
Challenge: Security, undoubtedly, is an integral part of the software development process, however, traditional SDLC follows a reactive (than a proactive) approach to it. As vulnerabilities are detected after the application is deployed to production, it results in slower release cycles, costly bug fixes, and delayed time-to-market of new features. Enterprises need to adopt a security-first mindset and proactively address related issues and concerns in the early stages of development.
Solution: Shift-left on security in DevOps empowers organizations to follow a proactive approach to security, compliance and regulatory challenges. Right from architecture design to development, deployment, and maintenance, shift-left approach is implemented to the entire software development lifecycle. By detecting and identifying potential security issues early on during development, development and operations teams can accelerate release cycles, reduce the likelihood of security breaches, and build robust and compliant software products. Shift-left on security also allows enterprises to continuously assess and improve security protocols to fulfill required compliance and regulatory requirements. And with a high-performance low-code platform like OutSystems, you can automate the security and vulnerability testing procedures across the SDLC and even while integrating with external third-party systems.
#4: Traceability and auditing solved by built-in version control
Challenge: As several developers together work on the same codebase, it often results in conflicts during code merging or when deploying different versions to different environments. Without version control, rollback to a previous version is impossible in events of critical issues. It is why enterprises must maintain a clear history of code changes and configuration for effective code management and control throughout the SDLC.
Solution: Built-in version control empowers enterprises to consistently maintain code quality, traceability, reusability and stability. OutSystems-led version management empowers organizations to store code and modules automatically in a centralized repository with clear details around code changes, merging only approved changes to the main codebase, and maintaining libraries and frameworks for effective code reusability. Its modular architecture and team collaboration module allows developers to easily navigate through different versions, rollback to an earlier one when critical incidents occur, track publication dates and authors for each version, and ensure the reliability of software deployment.
#5: High deployment overheads solved by deployment automation
Challenge: Manual deployments are time-consuming, heavily relies on individual-specific knowledge, and error-prone, often resulting in increased downtime and time-to-market, inconsistencies between environments with varying configurations, and introduce security issues. This becomes a bigger hurdle when enterprises frequently scale their software applications up and down due to varying loads.
Solution: Deployment automation is a critical aspect of successful DevOps implementation as it solves challenges around scalability, high overheads, resource availability, and limited visibility into the process. With OutSystems DevOps approach, you can leverage the convenient one-click feature to deploy user interfaces, workflows, integration components, and databases. Even better, OutSystems simplifies and accelerates deployment and application lifecycle management with AI-powered automation, runtime configurations such as batch scheduling, web service endpoints, along with built in governance. The high-performance low-code platform is highly scalable, and adapts to all your business requirements. To boost the performance and scalability of your software application, OutSystems allows you to integrate with different systems via APIs, SOAP and REST web services, and Forge components.
#6: Development and operations streamlined by CI/CD processes
Challenge: As mentioned before, CI/CD processes are the cornerstone for a successful DevOps implementation. During traditional development, integrating code changes is a complex and time-consuming process. Combined with slow and inconsistent testing procedures, it leads to bottlenecks in the development process and long release cycles. As developers do not have visibility into the development and deployment pipeline, manual processes can result in costly bug fixes especially at the production stage.
Solution: Implementing CI/CD processes helps enterprises tackle all the challenges associated with traditional development and testing, resulting in reliable and higher-quality software delivery. DevOps teams can break down code changes for automated testing and near real-time feedback. Whether your enterprise is in the early stage of implementing DevOps or are already on their CI/CD journey and wish to explore more opportunities for automation, OutSystems and its built-in capabilities can help you solve all your use cases.

- Lifetime, the infrastructure environment console in OutSystems checks code integrity and validates the overall quality of the software before releasing it to the next target environment, thus making deployment easy and error-free.
- With OutSystems you can build platform-agnostic applications that can be integrated with any type of system irrespective of its underlying framework or architecture. This means you can integrate any testing framework, automation platform, from any vendor with your OutSystems’ CI/CD pipeline via APIs, SOAP and REST web services, Forge components, or accelerators.
- With OutSystems, you can troubleshoot issues and bugs in your apps via its visually-driven and easy-to-use analytical dashboards and auditing tools, thus solving bottlenecks in real-time.
DevSecOps: The future of DevOps
Traditional software development often treats security as a separate concern, addressed only towards the end of the development cycle or during deployment. This approach can lead to vulnerabilities and security gaps, as security issues might go unnoticed until late stages of development. DevSecOps depicts development, security and operations to represent a collective approach of automating the integration of security at every stage of the application development. The framework works as a “Shift-left” approach where developers take responsibility for requirements gathering and analysis all the way to architecture design implementation, coding, management, deployment, testing and software development.
DevOps vs DevSecOps: A step forward for stringent security
While we talk about DevOps, DevSecOps also becomes an important point of discussion. So what is the difference between DevOps and DevSecOps? While both operate on the same methodology, here are some differences between the two.
|Point of Difference||DevSecOps ||OutSystems DevOps|
|Security||DevSecOps involves continuous security processes and stringent testing throughout application development. ||Security forms a critical aspect of OutSystems DevOps and, therefore, complies with the procedures of DevSecOps.|
