As organizations continue to embrace cloud computing, many are looking for the most effective way to modernize their applications and infrastructure. Two common approaches often discussed are cloud native and cloud hosted. While both leverage cloud technology, they differ significantly in terms of architecture, scalability, flexibility, and long-term business value.
Understanding the differences between cloud native and cloud hosted applications can help organizations make informed decisions about cloud migration, application modernization, and digital transformation initiatives.
What Is a Cloud Native Application?
A cloud native application is specifically designed and built to run in cloud environments. Rather than adapting traditional software for the cloud, cloud native applications are developed from the ground up using modern technologies and architectural principles that maximize the benefits of cloud computing.
Cloud native applications typically incorporate:
- Microservices architecture
- Containerization technologies such as Docker
- Container orchestration platforms like Kubernetes
- DevOps practices
- Continuous Integration and Continuous Deployment (CI/CD)
Instead of operating as a single monolithic system, cloud native applications consist of multiple independent services that can be developed, deployed, and scaled separately.
This approach allows organizations to improve agility, accelerate innovation, and optimize resource utilization.
What Is a Cloud Hosted Application?
A cloud hosted application is an existing application that has been moved from an on-premises environment to cloud infrastructure without significant architectural changes.
This migration strategy is commonly referred to as a "lift-and-shift" approach. The application continues to operate largely as it did before, but the underlying infrastructure is now hosted in a cloud environment rather than a physical data center.
Characteristics of cloud hosted applications include:
- Originally designed for on-premises deployment
- Typically hosted on virtual machines (VMs)
- Minimal changes to application architecture
- Faster migration timelines
- Lower initial modernization effort
Cloud hosted solutions allow organizations to benefit from cloud infrastructure while avoiding the complexity of rebuilding applications from scratch.
Cloud Native vs Cloud Hosted: Key Differences
Although both approaches utilize cloud environments, they differ in several critical areas.
1. Application Architecture
One of the biggest differences lies in application design.
Cloud hosted applications generally retain their original monolithic architecture. Since they were not specifically built for the cloud, their ability to fully leverage cloud services may be limited.
Cloud native applications are designed around microservices architecture, where individual services operate independently. This modular structure improves flexibility, maintainability, and scalability.
2. Scalability
Cloud native applications are built to support dynamic scaling. Resources can automatically expand or contract based on application demand, helping organizations optimize performance while controlling costs.
Cloud hosted applications can also scale, but scaling is often performed at the virtual machine level rather than at the service level. This can lead to less efficient resource utilization and increased operational expenses.
3. Development and Deployment Speed
Cloud native environments support Agile development practices and automated CI/CD pipelines. Development teams can deploy updates frequently and release new features quickly without disrupting users.
Cloud hosted applications often continue to rely on traditional deployment processes that may involve manual intervention, longer testing cycles, and scheduled maintenance windows.
As a result, innovation tends to occur more slowly compared to cloud native environments.
4. Maintenance and Updates
With cloud native architecture, updates can be applied to individual microservices without affecting the entire application.
This enables organizations to reduce downtime and simplify maintenance procedures.
In contrast, cloud hosted applications often require broader system updates, making maintenance more complex and potentially more disruptive.
5. Resource Efficiency
Cloud native applications are designed to maximize cloud resource utilization through containerization and automated orchestration.
Cloud hosted applications may consume more resources because they often maintain infrastructure requirements similar to their on-premises counterparts.
This difference can significantly impact long-term operational costs.
Benefits of Cloud Native Applications
Many organizations are adopting cloud native architectures because of their ability to support modern business requirements.
Improved Scalability
Applications can automatically adjust to changing workloads and user demand.
Faster Innovation
Automated deployment pipelines allow development teams to release updates and new features more rapidly.
Enhanced Resilience
Cloud native systems are designed with fault tolerance and self-healing capabilities, reducing the impact of infrastructure failures.
Greater Flexibility
Organizations can modify, replace, or scale individual services without affecting the entire application.
Multi-Cloud Compatibility
Cloud native technologies often support deployment across multiple cloud providers, reducing dependency on a single vendor.
Benefits of Cloud Hosted Applications
Despite the growing popularity of cloud native architectures, cloud hosted applications continue to offer valuable advantages.
Faster Cloud Adoption
Organizations can migrate existing applications to the cloud with minimal disruption.
Lower Upfront Costs
Because applications do not require complete redesign or redevelopment, implementation costs are often lower.
Reduced Migration Risk
Maintaining existing application architectures can simplify migration projects and reduce business risk.
Familiar Operational Processes
IT teams can continue using many of the tools and processes they already know, reducing the learning curve associated with cloud adoption.
Which Approach Should Your Organization Choose?
The right choice depends on your business objectives, existing infrastructure, budget, and modernization strategy.
Cloud hosted applications are often a practical solution for organizations seeking a fast and low-risk path to cloud adoption. They provide immediate infrastructure benefits without requiring major application changes.
Cloud native applications, however, offer greater long-term value for organizations that prioritize agility, scalability, innovation, and operational efficiency. Businesses developing new digital services or modernizing customer-facing applications frequently choose cloud native architectures to maximize their competitive advantage.
In many cases, organizations begin with cloud hosted environments and gradually modernize critical applications into cloud native architectures as part of their digital transformation journey.
Conclusion
Cloud native and cloud hosted applications both play important roles in modern cloud strategies, but they serve different business needs.
Cloud hosted applications enable organizations to quickly migrate existing workloads to cloud infrastructure with minimal changes. Cloud native applications are purpose-built for the cloud, delivering superior scalability, flexibility, resilience, and innovation capabilities.
By understanding the strengths of each approach, organizations can develop a cloud strategy that aligns with their current requirements while supporting future growth and digital transformation initiatives.
