Embracing Cloud-Native Principles
Sebastian Schürmann
Three abilities are the foundation of craftsmanship: to localise, to question and to open up. The first involves making a matter concrete; the second, reflecting on its qualities; the third, expanding its sense.
In the dynamic world of modern software development, cloud-native applications are rapidly gaining prominence. Designed to thrive in the ever-evolving cloud environment, these applications are built on a foundation of five key principles: scalability, resilience, manageability, observability, and automation. Delving into each of these principles, we can better understand their significance in creating successful cloud-native applications.
“Scalability inherently requires your functional ability not to be present.” (Richie Norton)
Scalability is a crucial aspect of cloud-native systems, ensuring that applications can handle fluctuations in demand without compromising performance or user experience. This principle refers to the ability of a cloud-native application to accommodate an increasing number of users, workloads, and transactions as demand grows. In short, scalability is about doing more with the same resources rather than simply increasing capacity.
"Everything fails, all the time" (Werner Vogels)
Resilience, another essential principle, is the capacity of a cloud-native application to recover quickly from failures and continue functioning without interruption. Maintaining user trust and minimizing costly downtime are important benefits of designing resilient systems. In short, resilience means acknowledging that failures will inevitably occur and proactively designing systems to bounce back quickly.

Manageability comes into play when considering the ease with which developers and operations teams can maintain, update, and evolve cloud-native applications. By ensuring that applications are manageable, organizations can reduce system complexity and streamline processes. In short, manageability is about embracing simplicity as a key driver of successful systems.
Just sit back and observe. You learn more that way (Sonya Teclai)
Observability is vital for monitoring, diagnosing, and understanding the behavior of cloud-native applications in real-time. This principle is essential for detecting and resolving issues before they impact end-users and for making informed decisions about system improvements. In short, observability aims to unlock the black box of distributed systems, providing insights into their inner workings.
The first rule of any technology used in a business is that automation applied to an efficient operation will magnify the efficiency. The second is that automation applied to an inefficient operation will magnify the inefficiency. (Bill Gates)
Finally, automation is the process of reducing manual intervention in cloud-native applications by automating repetitive tasks and processes. Embracing automation allows organizations to minimize human error, increase efficiency, and reduce the time it takes to deliver new features and updates. In short, automation is about enabling humans to focus on high-value work that machines can't do by automating routine tasks.
In conclusion, adopting the principles of scalability, resilience, manageability, observability, and automation can help organizations unlock the full potential of cloud-native applications. These principles not only ensure that applications can thrive in the dynamic cloud environment but also contribute to the long-term success and growth of businesses in today's competitive landscape.
