Digital transformation is now a priority for global organizations and Cloud-first strategy is the top agenda for CIOs worldwide. Organizations aim to revolutionize software delivery by developing and deploying applications natively in the Cloud. According to Gartner, “Technology leaders must deliver cloud-native offerings now to capture business opportunities and avoid irrelevancy.”
What are Cloud-native Applications
Cloud-native architecture approach enables businesses to build and run applications to leverage the elastic and distributed nature of modern Cloud Computing platforms. Cloud-native applications offer the organizations a more agile environment and greater portability across Cloud. According to Cloud Native Computing Foundation (CNCF) “Cloud-native” narrowly means using a software stack to develop and deploy applications in a way where each part of the app is packaged in its own container, dynamically orchestrated such that every component is actively scheduled and managed to optimize resource utilization and enhance performance. Furthermore, microservices-based implementation helps to increase the overall agility and maintenance of Cloud-native applications.
DevOps: An Enabler for Cloud-native Application Development
DevOps and Cloud-Native applications are complementary. The need to simplify and accelerate the application development and delivery process makes DevOps the leading enabler to get the Cloud.
According to Gartner, 28 Percent of total spending in key IT segments will shift to the Cloud by 2022. With massive scale shift from on-premise IT infrastructure to the Cloud, Cloud-native applications lead the way for companies to gain momentum in the market. Scalability, resilience, and portability across various cloud environments increase the demand for Cloud-native applications. The fast-paced shift requires effective automation of agile methodology to meet rapidly changing customer requirements.
Let's take a closer look at key aspects that make DevOps imperative for Cloud-native applications:
Cloud-native technologies such as microservices and containers are based on key DevOps principles- continuous integration (CI) and continuous delivery (CD). Cloud-native applications are better managed via CI/CD pipeline to ensure an agile development process.
DevOps, Not an Event
Unlike the traditional monolithic approach where the development and operations teams operate in silos, DevOps create an environment wherein the complete software development process is conducted as an ongoing cycle in a fast-paced and continuous ecosystem. DevOps creates a culture of continuous delivery for Cloud-native applications.
Supports Containerization and Microservice Architecture
Business-critical applications based on microservices architecture or containerization need a robust and reliable approach to software development and delivery to avoid any service failure and business loss. Embracing DevOps methodology is inevitable to ensure continuous updates and better performance with minimum latency.
Benefits of Adopting DevOps for Cloud-native Applications
DevOps provides more focus on continuous delivery, development, and integration. The key function of DevOps and the Cloud are in synergy. Businesses are better off when both the methodologies are implemented coherently.
Businesses building Cloud-native applications adopt DevOps to leverage the following key benefits:
DevOps facilitate organizations to plan, build, test and run cloud-native applications to meet the rapidly changing customer requirements faster than the competition. The automatic CI/CD pipeline accelerates the application delivery process. Continuous integration and delivery make the development process more predictable over time and ensures a smooth and reliable development and delivery cycle.
Reduced Number of Defects
DevOps bridges the gap between development and operations teams which lays down the foundation for seamlessly implementing cloud-native approaches including microservices architecture and containerization in the Cloud. With more transparent processes, modular programming and better collaboration between teams, enterprises witness a drastic reduction in the number of defects in the application delivered to the customers.
Improved Frequency of New Features and Updates
Innovation and continuous improvement are major drivers of success for any Cloud-native application. DevOps empowers enterprises to quickly innovate and embrace customer feedback by developing and delivering application features without any delay. DevOps makes it easy for businesses to incorporate customer feedback and release updates faster than ever before.
Enhanced Application Performance
Cloud-native applications need to be more fault-tolerant to avoid any scenarios leading to downtime. DevOps enables effective implementation of Cloud-native strategies, like microservices architecture and containerization, that are ideal in isolating the impact of any specific incident or module failure. The modular application design helps in achieving higher uptime and delivering better user experience.
Migration from traditional monolithic software development processes to Cloud-native environment needs agility. DevOps introduces scalability and flexibility to ensure business processes agility. It facilitates better communication and integration among teams, functions, and processes to formulate better plans, get quick stakeholder buy-in, and initiate faster implementation.
Automation is one of the primary aspects of DevOps and helps minimize manual efforts and waste of resources by automating repetitive tasks. It also curtails errors and helps in minimizing overall operational costs.
Cloud-native applications and DevOps are a perfect blend for digital transformation plan. Synergised implementation of both the approaches not just results in better and faster software releases but also improves application performance and user experience. Also, DevOps is imminent to implement cloud-native approaches such as containers and microservices to support modern cloud-native applications. DevOps is imperative to ensure minimum friction in cloud-native applications workflows.
