Cloud‑native is a software development approach widely used in travel technology, where applications for airlines, hotels, and travel platforms are designed to run and scale natively in cloud environments such as AWS, Azure, or Google Cloud. Unlike cloud‑enabled legacy systems, cloud‑native travel applications are built as loosely coupled microservices, enabling rapid deployment, automatic scaling, and high resilience across complex, high‑volume travel operations.
The defining characteristic of a cloud-native technology in the travel sector is the shift from monolithic to microservices architecture.
Travel has extreme demand spikes (e.g., Black Friday or a flash fare sale). Cloud-native technology solves this using auto-scaling.
Legacy data centers are mostly static in capacity; if the traffic gets beyond the server capacity, the website crashes. Traffic monitoring is conducted in real-time by cloud-native systems. If 100 thousand users start suddenly searching for flights, the system will automatically spin up more computing resources (containers) to handle the load. When there is less traffic, it spins them down to save money. This is necessary to control the industry’s huge look-to-book ratios.
Cloud-native makes Continuous Integration/Continuous Deployment (CI/CD) possible. Instead of the traditional waterfall approach, where an airline would have one major software release every 6 months, cloud-native travel companies can make updates multiple times each day. This enables quick A/B testing of new features (such as a new upsell placement) without compromising system stability.
Cloud-based usually means taking existing legacy software and hosting the software on a remote server (Lift and Shift). It runs in the cloud but is not entirely cloud-based. Cloud-native refers to the software that was rewritten from scratch using containers and microservices to make the most of the flexibility offered by the cloud.
Containers are the default unit of software for cloud-native tech. They package up the code along with all its dependencies so that the application runs quickly and reliably from computing environment to computing environment. Kubernetes is the system that is used to manage (orchestrate) these containers at scale.
Generally, yes. Cloud providers spend billions on security. Furthermore, since cloud-native apps are compartmentalized (microservices), an attack in one part (such as the blog) does not necessarily mean that the core database (such as credit card data) can be accessed.
