Compare PaaS providers: how to choose the right cloud application platform
Your cloud platform shapes how fast your team ships, how well your apps scale, and how much time your engineers spend on infrastructure. The right one handles that, so your team can focus on the product.
Cloud platform categories and constraints
Cloud platforms give you a managed environment to build, deploy, and scale your applications. Most, however, come with limitations that only surface once you're committed. Understanding which category a provider belongs to tells you what it was built to optimize and where it falls short.
| Criteria | Specialized platforms (Vercel · Netlify · Pantheon · Acquia) | Developer-first (Heroku · Render) | Hyperscalers (AWS · Azure · GCP) | Cloud application platform (Upsun) |
|---|---|---|---|---|
| Preview environment | Frontend or CMS previews; full-stack not cloned | App previews only; stateful services excluded | Build it yourself | Full-stack clone per branch (apps, DBs, services, queues) |
| Multicloud options | Single cloud, vendor-managed | Single cloud (AWS) | Single hyperscaler | AWS, Azure, GCP, IBM, OVH (14 regions) |
| Pricing model | Usage-based/tier-bound per site | Dyno + per-add-on; breaks at scale | Hard to predict, easy to leak | Predictable and transparent model |
| Security and compliance | Narrower than enterprise needs | Shallow audit, no sovereignty | Shared responsibility(you implement most) | GDPR, SOC2, ISO; RBAC, SSO/SAML, audit logs; sovereignty options |
| Dev autonomy + governance | Minimal | Limited controls | Build it yourself (IAM, IaC) | Platform-as-code; RBAC, SSO included |
| Built-in observability | Basic platform metrics | Bolt-on required | Integrate separately(APM bolt-on) | Native APM and profiling (Blackfire) |
| Enterprise SLA | Enterprise tier only | Plan-tier dependent | Per service; you stitch | 99.99% uptime SLA available |
What to consider when choosing a cloud platform
Preview environments that reflect production
Bugs found in production cost time and weaken customer trust. Preview environments that clone production, including data and services, catch issues on every branch before release.
Cloud flexibility and portability
Deploy across AWS, GCP, Azure, IBM Cloud, and OVHcloud without rebuilding your infrastructure. You control where your data lives, meet regional requirements, and optimize cost.
Pricing predictability
Predictable pricing model means you can calculate infrastructure costs before you commit and forecast as you scale. You define what your application uses and pay for that allocation.
Operational load on your team
Whatever the platform doesn't handle, your engineers do: observability, environment setup, compliance, infrastructure, and incident response. The right platform reduces this load.
Deployment speed and CI/CD integration
How long it takes to move from a code commit to a live environment sets your delivery pace. Manual setup and slow pipelines hold teams back without adding safety.
Governance without slowing down delivery
The right platform gives engineering teams speed to ship while keeping compliance teams confident about access controls and auditability.
Build, ship, and scale without the overhead
Upsun is built for teams running production workloads past the limits of frontend-first platforms or simpler PaaS without the operational burden of running on a hyperscaler.
- Full-stack previews: Upsun clones code, data, and services on every branch.
- Multicloud options: Deploy to AWS, GCP, Azure, IBM Cloud, or OVHcloud from one workflow. Switch providers without rewriting infrastructure.
- Compliance built in: SOC 2 Type 2, PCI DSS Level 1, HIPAA, GDPR, and ISO 27001 come with the platform, not as add-on tiers.
- Full-stack support: Built for stateful apps and frameworks like Laravel, Django, Drupal, Symfony, Next.js, and Magento.
- Predictable pricing: Pay for the resources you define. Forecast costs before you commit.
- Managed operations: Environment setup, observability, and incident response come with the platform.
Is Upsun the right fit for your team?
Upsun takes infrastructure off your team so they can ship. That's the right move for most workloads; however, not every workload. Here's how to tell where Upsun fits.
✓ Upsun is built for
Teams running production workloads on complex stacks who need a platform that scales with them.
- Production applications on frameworks like Laravel, Django, Drupal, Symfony, Next.js, or Magento.
- Engineering teams that run on AWS, GCP, Azure, IBM Cloud, or OVHcloud or plan to switch.
- Companies with compliance requirements (SOC 2, ISO 27001, GDPR, PCI DSS, HIPAA).
- Organizations that want managed platform operations without hyperscaler complexity.
✗ Upsun isn't built for
Some workloads are better served by other tools. Upsun isn't the right fit for:
- Purely static sites with no backend, services, or data layer to manage.
- Workloads that need direct, low-level cloud infrastructure access.
- Hobby projects or short-lived prototypes that don't need production guarantees.
- Teams optimizing only for the lowest hosting cost on a small scale.

How does Upsun pricing work, and how do I estimate costs before committing?
Upsun charges based on resources allocated to your applications: compute, RAM, and storage per environment. You define resources in the configuration, so costs reflect what you've allocated rather than unpredictable usage spikes. You can model costs accurately before you commit.
How does Upsun handle scaling, and what are the limits?
Upsun supports horizontal autoscaling: the platform adds application instances in response to traffic load without manual intervention. Vertical scaling, increasing compute or RAM for a specific service, is a manual configuration change. If your scaling requirements are primarily traffic-driven, horizontal autoscaling handles it. If your workload needs a larger instance type, that's a configuration decision. There are no artificial platform ceilings; resource limits reflect what you configure and pay for.
Where do applications run, and can we control data residency?
Upsun runs on AWS, Azure, GCP, IBM Cloud, and OVH. You choose the provider and region at setup. For organizations under GDPR or data sovereignty requirements, your data sits in the region you select that choice is explicit and verifiable. Upsun does not operate automated cross-region failover by default; failover is an operational decision your team makes, not an automatic platform behavior.
What compliance certifications does Upsun hold?
SOC 2 Type 2, PCI DSS Level 1, GDPR, HIPAA, and ISO 27001. These are platform-level certifications covering Upsun's infrastructure and operational controls, not the underlying cloud provider's compliance layer. For procurement processes, certification documentation is available on request.
Does Upsun lock us into a specific cloud provider?
No. Infrastructure configuration is written in YAML and is not tied to provider-specific APIs or services. Moving between AWS, GCP, Azure, OVH, or IBM Cloud does not require rewriting your infrastructure. You do take a dependency on Upsun as a vendor, which is a smaller and more reversible switching cost than provider-specific infrastructure code but it is not zero.
How is Upsun different from managing infrastructure directly on AWS or GCP?
On a hyperscaler, your team builds and maintains the platform layer: environment provisioning, deployment pipelines, observability tooling, and compliance controls. That is ongoing engineering work. Upsun delivers those capabilities as the product. The tradeoff is control: hyperscalers give more granular infrastructure access; Upsun manages it on your behalf. For teams whose core competency is their application rather than platform engineering, that tradeoff typically reduces total engineering cost.
If you’re evaluating external hosting, Upsun should definitely be part of your evaluation.
