An Introduction to Cloud-Native Applications

This is part one in a three-part series on the evolution to cloud-native application development. Next week’s part two will cover cloud-native API management, and tune in February 19 for a special cloud-native announcement.

Applications drive successful digital platforms, and their development and management continue to evolve. While many businesses still operate substantial legacy tech on-premises, many are looking to the cloud for development. But what does it mean to develop a cloud-native app, and why should you care?

Rather than implying where an app resides, cloud-native refers to how it was created and deployed. Cloud-native apps are developed with tools that allow them to take full advantage of cloud benefits, meaning they can be built and changed more quickly, are more agile and scalable, and can be connected with other existing apps more easily.

Now that you understand cloud-native as a concept, let’s explore some of the best practices developers use when creating cloud-native apps, as well as why those elements are vital in driving innovation.

Microservices

Cloud-native apps are developed with loosely-coupled microservices, allowing each microservice to function only as needed, as well as be updated/altered as needed, rather than requiring the full application to run aggregately.

Scalability

Cloud-native apps are deployed on self-service, shared infrastructure, and are built to be elastic and scalable. They are able to scale up to utilize more cloud resources when required while taking up as little bandwidth as possible otherwise. This is beneficial because apps often share tenancy with others, and the ebb and flow of resources can be shared as necessary.

Containerization

Cloud-native apps are built to be a collection of independent, autonomous services packaged together in lightweight containers. These containers are built to be scalable, as well as fully independent from other another. Because the unit of scaling shifts to the containers, the resource utilization is optimized.

Tooling

Best-of-breed languages and frameworks are used in the development of cloud-native apps. In order to create the best app possible, developers will pick and choose which tools to implement into each microservice, which allows the completed application to have the most efficient functionality possible.

DevOps

Each microservice of a cloud-native app goes through an independent life cycle, managed via an agile DevOps process. For the app to function properly, multiple continuous integration/continuous delivery (CI/CD) routes will work together to deploy and manage the application.
There are myriad other features of cloud-native apps that allow them to be faster, more flexible, and more efficient than their legacy counterparts. To learn more about how TIBCO® can help you learn more about cloud-native technologies, check out TIBCO.com
