Cloud application development that's cloud-native from the first line of code.
We build applications as microservices, serverless functions, and containers from day one — not a traditional app that happens to be hosted on a cloud server.
What is cloud application development?
Cloud application development is building software as microservices, serverless functions, and containers from the first line of code, rather than building a traditional application and hosting it on a cloud server afterward. The architecture itself is designed for the cloud: independent, deployable-on-their-own components instead of one large codebase everyone has to redeploy together.
Over 80% of enterprise applications now rely on microservices for modularity and fault isolation, and serverless computing has grown from a $26.51 billion market in 2025 to $32.59 billion in 2026. The appeal is practical: teams ship features independently instead of coordinating one large release, and serverless compute typically cuts infrastructure costs by 40% to 60% against always-on servers, since you pay for what actually runs, not idle capacity.
- Independent deploys
- Ship one service without redeploying the whole application.
- Pay for what runs
- Serverless compute bills on usage, not idle capacity.
- Identical environments
- Containers behave the same in dev, test, and production.
- No provider lock-in
- Portable equivalents chosen over provider-specific services.
Cloud apps, Cloud SaaS Apps, or Cloud Solutions?
All three build or move things in the cloud. The starting point is what differs.
| Service | What it covers | Best fit |
|---|---|---|
| Cloud Application Development | The architectural approach — microservices, serverless, containers — applied to any new application. | A new internal tool, customer portal, or mobile backend built cloud-native from scratch. |
| Cloud SaaS Apps | That same cloud-native approach, applied specifically to multi-tenant SaaS products with billing and tenant isolation. | A SaaS product that needs to scale across many customer accounts. |
| Cloud Solutions | Migrating an application that already exists and works, rather than building something new. | An existing on-premise or legacy application that needs to move to the cloud. |
Three paths for modernizing an app you already have.
Not every legacy application needs a full rebuild. The right path depends on how much runway it needs.
| Path | What it means | Best fit |
|---|---|---|
| Rehost | Move the application to the cloud as-is, with minimal code changes. | Non-critical systems where migration speed matters more than long-term efficiency. |
| Refactor | Adjust code for better cloud efficiency without a full rebuild. | Applications that work but need moderate performance or cost improvements. |
| Rearchitect | Rebuild with microservices and cloud-native patterns for maximum scalability. | Applications expected to grow significantly, where long-term ROI justifies the upfront cost. |
Cloud applications we build most often.
Rearchitecting costs the most upfront and delivers the strongest long-term efficiency. We recommend the path that matches your growth plans, not automatically the most technically impressive one.
Microservices applications
Applications split into independent, deployable services communicating through APIs, so teams ship features without coordinating one big release.
Serverless applications
Event-driven functions that run on demand and scale automatically, ideal for variable or unpredictable traffic patterns.
Container-native applications
Applications packaged in containers for identical behavior across development, testing, and production environments.
Mobile & API backends
Cloud-native backends for mobile apps, built to scale independently from the app's front end as usage grows.
Internal & enterprise tools
Internal applications built cloud-native from the start, avoiding the technical debt of a monolith that outgrows itself in two years.
Legacy application rearchitecture
Rebuilding an existing monolith as microservices, using the 3R framework to scope the right level of change.
A clear path from concept to a cloud-native application.
Four stages, with CI/CD live from the first service rather than bolted on at the end.
Architecture scoping
We map your application's components and decide which need microservices, serverless, or a simpler monolith.
1–2 weeks · ScopingService & infrastructure design
We design service boundaries, APIs, and infrastructure as code before writing application logic.
1–3 weeks · DesignBuild & deploy in sprints
We build and deploy services incrementally, with CI/CD live from the first service, not bolted on at the end.
6–20 weeks · BuildLaunch & scale-test
We load-test scaling behavior before real traffic arrives, then hand over a fully documented system.

Cloud-Native · Full-Stack · Rearchitecture
A broken multi-stack system rebuilt as one cloud-native platform
BeesApp was running on a fragile mix of PHP, Django, and Vue, unable to scale under real usage. We rearchitected it as a single cloud-native platform on Next.js and FastAPI, with 120+ API endpoints and automated inventory across a multi-vendor marketplace — the rearchitect path from the 3R framework, chosen because the business needed real long-term scalability, not a quick lift-and-shift.

ExploreCloud application development questions
The things clients ask us most before starting a cloud-native build.
Cloud application development is building software as microservices, serverless functions, and containers from the first line of code, rather than building a traditional application and hosting it on a cloud server afterward. The architecture itself is designed for the cloud, not just deployed to one.
Cloud Application Development covers the architectural approach — microservices, serverless, containers — for any new application: internal tools, customer portals, mobile backends. Cloud SaaS Apps applies that same approach specifically to multi-tenant SaaS products with per-customer billing and isolation. If you're building a SaaS product, start there; for anything else built cloud-native, this is the right page.
Build cloud-native if you're starting a new application or the current one needs to scale and change faster than its current architecture allows. Migrate as-is if the application works fine and simply needs cloud hosting, which is a Cloud Solutions migration project, not a rebuild.
The 3R strategy names three modernization paths: rehosting, moving an application to the cloud as-is; refactoring, adjusting code for better cloud efficiency without a full rebuild; and rearchitecting, rebuilding with microservices for maximum scalability. Rearchitecting costs the most upfront but delivers the strongest long-term performance and cost efficiency.
Yes. Serverless computing charges only for actual compute used rather than idle server time, which typically cuts infrastructure costs by 40% to 60% compared to always-on servers, particularly for applications with variable or unpredictable traffic.
Yes. Mobile backends built as microservices with API-driven architecture scale independently from the app itself, so a spike in one feature's usage doesn't slow down the rest of the app.
No, not by default. We build with infrastructure as code and avoid provider-specific services where a portable equivalent exists, so your application can run on AWS, Azure, or Google Cloud without a rewrite.
Yes. You own 100% of the application code and infrastructure definitions in documented repositories, with no dependency on us to operate or extend it.
