What is cloud native in simple terms?

Answered by Willian Lymon

Cloud native refers to the approach of designing and building applications that fully leverage the capabilities and benefits of the cloud. It involves creating applications that are specifically tailored to take advantage of the distributed nature of cloud computing.

When we talk about cloud native, we are essentially talking about applications that are born in the cloud. These applications are designed from the ground up to be deployed and run in the cloud environment, rather than being adapted or migrated from traditional on-premises systems.

One of the key principles of cloud native is scalability. Cloud native applications are designed to scale horizontally, meaning that they can easily handle increased workloads by adding more instances of the application across multiple servers or nodes. This allows the application to efficiently handle spikes in demand without sacrificing performance.

Elasticity is another important aspect of cloud native. Cloud native applications can dynamically adjust their resource usage based on demand. They can automatically scale up or down in response to changing workload requirements. This flexibility ensures that the application always has the right amount of resources allocated to it, optimizing efficiency and cost-effectiveness.

Resiliency is another characteristic of cloud native applications. They are designed to be fault-tolerant and capable of withstanding failures at various levels, such as hardware failures, network issues, or even entire data centers going offline. Cloud native applications are built with redundancy and failover mechanisms, ensuring that they can continue to operate even in the face of disruptions.

Flexibility is a key benefit of cloud native. These applications are built using modular and loosely coupled components, allowing for easier updates, upgrades, and maintenance. They can take advantage of cloud-based services and APIs, enabling developers to quickly integrate additional functionality without having to reinvent the wheel.

In my personal experience, I have witnessed the transformation of applications from traditional monolithic architectures to cloud native architectures. This shift has allowed organizations to harness the full potential of the cloud, enabling them to rapidly scale their applications, improve reliability, and take advantage of the latest cloud technologies.

To summarize, cloud native is about designing and building applications that are optimized for the cloud environment. These applications are scalable, elastic, resilient, and flexible, taking full advantage of the distributed nature of cloud computing. By embracing cloud native principles, organizations can unlock the true potential of the cloud and drive innovation in their digital transformation journey.
