Introduction
As the head of engineering at a leading IT company, I often discuss issues with business leaders, other engineering heads, and CTOs from the industry. During our chats, one question comes up every now and then:
Which type of cloud should we choose for our workloads? Public, Private, or Hybrid?
A few years back, the debate was whether to move to the cloud. Now, almost every company is on the cloud or on the road to adoption. The big question is how to match workloads to the right model without creating any problems for the future.
Don’t worry!
Based on my experience in my role and the knowledge I have gained from the market, I have curated this article to help you decide between public, private, and hybrid cloud models.
A Detailed Overview of Public, Private, and Hybrid Cloud Models
Below is a detailed overview of the three main cloud deployment models. Read further to discover more details and get help making the right choice.
1. Public Cloud
Let’s start the discussion with our first deployment model in the list: Public Cloud.
This cloud deployment model is the most flexible option in the list. With public cloud, you can get resources on demand, pay only for what you use, and scale up or down as needed. If your workloads are unpredictable, public cloud saves you from over-provisioning.
This model is best suited for customer-facing apps, testing environments, and analytics platforms, as they need speed and elasticity. Developers also get ready-to-use services like managed databases, monitoring, and container orchestration that take away a lot of manual effort.
Now, the challenge is cost and compliance. I’ve seen teams add up huge bills because nobody kept track of what was running. And while these public cloud service providers offer strong security, compliance is not something that they will take care of. It’s your responsibility.
2. Private Cloud
Private cloud makes more sense when control is more important than speed. Call it a coincidence, but I have seen this model adopted mostly in regulated industries like healthcare, banking, and government. As companies in these sectors have to deal with sensitive data, strict compliance, and predictable performance, these factors might push them to keep workloads in private environments.
The benefit of a private cloud infrastructure is peace of mind. You decide how data is stored, who accesses it, and how security rules are enforced. For businesses with zero tolerance for risk, this feels safer.
But this peace comes with a cost. Private cloud requires heavy upfront investment in hardware, data centers, and even skilled teams to maintain. Scaling is also slower. If your workloads don’t absolutely demand that level of control, a private cloud can become an expensive choice.
3. Hybrid Cloud
Many companies eventually land in a hybrid cloud, either because they were unable to make a choice or because they wanted to enjoy the best of both worlds.
With this cloud deployment model. You can combine the strengths of public and private cloud. Sensitive data and regulated workloads stay private, while applications that need scale and speed run in the public cloud.
I’ve seen this work well when companies want to move to the cloud gradually. It avoids the “all or nothing” problem. You don’t have to migrate everything at once, as you can shift your workloads step by step.
However, this model has a downside: Integration complexity. Monitoring, security policies, and team processes need to work across both environments. If that isn’t planned properly, hybrid setups can actually become a roadblock rather than a road to success.

How to Decide between Public vs Private vs Hybrid Cloud?
When I’m working with teams, I don’t start by asking them which cloud they prefer. I start by asking about the workloads. A few questions usually guide the choice:
- How sensitive is the data?
- What regulations do you need to meet?
- How fast does this workload need to scale?
- What skills and budget does your team already have?
If the workload is unpredictable or customer-facing, the public cloud usually wins. If it is highly sensitive or regulated, a private cloud is safer. And if the business runs a mix of both, a hybrid cloud model often becomes the right answer.
The key is not to copy what another company is doing. It’s about aligning the cloud model with your business needs, your workloads, and your long-term plans.
My Recommendation Moving Forward
Picking between public, private, and hybrid cloud is only half the job. What really matters is what you do after making the choice. I’ve seen companies choose the right model but still run into trouble because they didn’t plan how to manage it.
Public cloud can easily drain loads of money if you do not monitor it properly. Private cloud can slow you down if you don’t have the right people and processes in place. And a hybrid cloud setup, while flexible, can easily get messy without proper integration.
That’s why I always tell teams not to just choose your cloud but to plan for how you will run it day to day. This is where I recommend cloud managed services. A trusted third party service provider with deep experience in cloud management can help you make the choice and execute it well, so you can yield maximum results, with minimum pitfalls.
