Cloud native generally refers to software that is designed from the ground up to take advantage of what cloud computing infrastructure provides: flexibility, scale, resilience, and elasticity.
Applications built for the cloud offer new and better customer experiences, speed, reduced costs, and ease of management.
Cloud native is a two-fold term. One meaning is the descriptor or definition of the approach of designing software applications specifically for cloud architecture. It may refer to the tools, technologies, and techniques used to build cloud native software, which are different from the tools and approaches used to build legacy software. The second meaning describes the characteristics of these applications and services, often as “cloud native apps.” It refers to more than the locations where applications are to be deployed; it also refers to how they are developed.
Cloud native applications are designed to be loosely coupled, be optimized for cloud performance, and favor managed services provided by cloud vendors. They are built under a continuous delivery methodology, and this steady delivery of innovative ideas, experiences, and improvements as software is pointed squarely at gaining competitive advantage through speed and improved customer experience.
Companies including Netflix, Uber, and Airbnb are examples of “born in the cloud” — cloud service companies that are not built on legacy systems and have instead been specifically engineered to take full advantage of modern cloud infrastructure and delivery.
The Cloud Native Computing Foundation (CNCF), part of the nonprofit Linux Foundation, hosts important components of the global technology infrastructure. CNCF offers a more technical definition of cloud native:
“Cloud native technology empowers organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds. Containers, service meshes, microservices, immutable infrastructure, and declarative APIs exemplify this approach. These techniques enable loosely coupled systems that are resilient, manageable, and observable. Combined with robust automation, they allow engineers to make high-impact changes frequently and predictably with minimal toil.”
This component-based development and deployment of software takes the approach that the infrastructure is separate from the application, and the infrastructure is disposable. It can be provisioned quickly and removed when it’s not necessary. When infrastructure fails or is outdated, it is not modified or repaired; it’s replaced, automatically. This is what is meant by immutable. As more services are needed, they are scaled out. When they are no longer needed, they are removed
Cloud native is fueled by the quest to rapidly turn ideas into customer experiences in the market. Businesses are undergoing digital transformation at a rapid pace, seeking to turn processes digital in order to deliver better, richer, customer experiences faster, all with the goal of accelerating growth.
Examples of these experiences may include dynamic changes for customizing a purchase, or features such as modeling a customer-designed product configuration prior to purchasing it, or comparing feature sets across products. When a customer suggests or requests a feature, or a line of business owner dreams of an idea, IT and the business can quickly turn it into application software in a cloud native architecture.
Delivering these services is highly dependent on performance as well. Customers expect rapid answers and continuous service availability through a network that doesn’t go down. They want new features delivered digitally as soon as they are conceived, in a customer experience that is innovative and memorable and offers business value.
Cloud native applications address the dual goals of speed of innovation and reliability. They can be quickly developed and deployed and rapidly evolved and scaled across cloud environments. IDC predicted in a 2020 Futurescape report that more than 90% of apps will be cloud native by 2025, and that nearly two-thirds of enterprises will be prolific software producers that deploy code daily.
A key strength of cloud native architectures is that they are standards-based and vendor neutral. This interchangeability allows software to be developed and deployed to work the same way over any number of hardware and cloud configurations.
Some of the building blocks of cloud native have become mainstream, according to a 2021 survey done by CNCF.
“Kubernetes adoption among the ever-expanding cloud native community is approaching 100%”
Priyanka Sharma, CNCF executive director, said in 2022 when the survey data was released.
“Our data also demonstrates how ubiquitous cloud native is, whether it is being deployed in house or as a managed service. I believe 2022 will be a banner year for emerging areas of cloud native, like edge, observability, and security, as container infrastructures continue to mature both on the surface and under the hood.”
Essential components of cloud native applications include:
Cloud native software development offers advantages in several areas at a time when organizations are readily harnessing the technology necessary to make these benefits a reality. Benefits such as expense avoidance and speed play in multiple areas.
