PaaS Deployment Models: Public, Private and Hybrid PaaS Explained

When people say “PaaS”, they often picture one thing. In reality, PaaS can be set up in different ways. These are called deployment models, and choosing the right one affects cost, control and security.

Quick answer: There are three main PaaS deployment models. Public PaaS runs on shared cloud infrastructure managed by a provider. Private PaaS runs on infrastructure used by only one organisation. Hybrid PaaS mixes both, so some workloads run in a shared environment and others in a private one.

New to the topic? Our guide on what PaaS is is a good place to begin.

What Does “Deployment Model” Mean?

A deployment model tells you where your platform runs and who can use that environment. Think of it like choosing where to live. You can rent in a shared building, own a private house, or keep a home and an office in two places.

1. Public PaaS

In a public PaaS, the provider runs the platform on shared cloud infrastructure. Many customers use the same underlying system, but their applications are kept separate.

Good things about public PaaS:

• Quick to start
• Usually the most affordable model
• The provider handles maintenance, updates and scaling
• Easy to grow as your traffic grows

Things to think about:

• You have less control over the underlying infrastructure
• Some strict compliance needs may require more isolation

Our PaaS platform is designed to give teams this kind of managed, ready to use experience, with application, database and storage services in one place.

2. Private PaaS

A private PaaS runs on infrastructure used only by one organisation. It may sit in the organisation’s own data centre or on dedicated resources.

Good things about private PaaS:

• More control over security and configuration
• Easier to meet strict internal or industry rules
• Resources are not shared with other customers

Things to think about:

• Higher cost
• More planning and management needed
• Slower to set up than a public option

Private PaaS often suits large companies, regulated businesses or teams with sensitive data.

3. Hybrid PaaS

Hybrid PaaS combines public and private. A company might keep sensitive data on private resources while running its public website and development environments on a shared platform.

Good things about hybrid PaaS:

• Flexibility to place each workload where it fits best
• Can balance cost and control
• Lets you move gradually instead of all at once

Things to think about:

• More moving parts to manage
• Needs clear planning so data and apps connect smoothly

Public vs Private vs Hybrid PaaS at a Glance

Feature	Public PaaS	Private PaaS	Hybrid PaaS
Who uses the infrastructure	Many customers, kept separate	One organisation	A mix of both
Cost	Usually lower	Usually higher	In between
Control	Moderate	High	Flexible
Setup speed	Fast	Slower	Medium
Best for	Startups, agencies, growing apps	Regulated or sensitive workloads	Teams with mixed needs

How to Choose the Right Model

Ask these questions:

1. How sensitive is my data? Highly sensitive or regulated data may point toward private or hybrid.
2. What is my budget? Public PaaS is usually the easiest on cost.
3. How fast do I need to launch? Public PaaS is usually the quickest.
4. How much control do I need? If you need deep control, consider private or other server based options.
5. Will my needs change? Hybrid gives room to adjust over time.

For most startups, agencies and growing businesses, starting with a managed public style platform is a practical choice. You can see how our plans work on the PaaS pricing page.

What Services Fit Into Each Model?

Whatever model you pick, the same building blocks matter:

• Applications: see our application hosting, including PHP hosting and Laravel hosting
• Databases: our managed databases cover MySQL, PostgreSQL, MariaDB and MongoDB
• Storage: our storage services and file storage

To see how these layers connect, read our guide on PaaS architecture.

Deployment Model vs Service Model

People sometimes mix these up. A service model is the type of cloud service, such as IaaS, PaaS or SaaS. A deployment model is where and how it runs, such as public, private or hybrid. You can read about the first group in our comparison of PaaS vs IaaS vs SaaS.

Final Thoughts

Public, private and hybrid PaaS each solve a different problem. Public is simple and cost friendly, private gives control, and hybrid gives flexibility. Start from your data, budget and growth plans, and the right model usually becomes clear.

Frequently Asked Questions

Which PaaS model is the cheapest? Public PaaS is usually the most affordable because infrastructure is shared and managed by the provider.

Is public PaaS safe? Reputable providers isolate customer environments and apply security measures. Still, always check the provider’s security features against your needs.

When should I choose private PaaS? When you handle highly sensitive data, face strict compliance rules or need full control over the environment.

Can I move from public to hybrid later? Often yes, but plan for it early so your applications and data can move smoothly.
