Key Takeaways
- Private and public clouds each have benefits for investment firms.
- Using the cloud provides companies with a secure, flexible hosting environment.
- In private cloud vs. public cloud, there’s a third option, which is a hybrid that combines the advantages of both.
By 2033, the public cloud market will reach a value of $3,349.61 billion at a CAGR of 16%.
Despite this significant spending, companies also still use private clouds to host their company data, and some companies even use both. With the heavy investment and adoption of the technology, it’s a good time to answer which is better: private cloud vs. public cloud.
While public clouds are becoming more popular and beneficial for companies looking to scale, private clouds still have advantages. In this article, explore the differences between public and private clouds.
What Is a Private Cloud?
A private cloud is a data center hosted by a single company’s infrastructure. Organizations have complete control over this cloud and can ensure firewalls and secure protocols protect it. Larger companies like enterprises typically have these clouds because they’re the only ones with the infrastructure to support them.
While using private cloud providers is advantageous, not every company can manage or afford it. A business must have a team to protect, manage, and support a private cloud. Private clouds also need upgrades and replacements occasionally, which can be costly.
What Is a Public Cloud?
On the other hand, a public cloud is perfect for companies that don’t have the infrastructure to support a private one. Google Cloud and AWS are public cloud providers and host the cloud for companies to use.
Firms can use public clouds as a backup in case their private cloud fails, or they might leverage them to share data in multiple environments.
The main benefit of using a public cloud is that organizations don’t need an entire team to manage the cloud. However, one downside is that businesses aren’t in total control of the cloud.
A public cloud is ideal for those seeking:
- Supporting business continuity
- Outsourcing IT tasks
- Backing up archival data
- Offloading applications to lower latency
- Reducing the need for on-site infrastructure support
Difference Between Public and Private Cloud
The best way to understand the differences between a private cloud vs. public cloud is this: a private cloud is like listening to music from owned CDs versus streaming music on a shared site like Spotify or Apple Music.
One company will control its private cloud, and no one else can access it. However, a public cloud is one large service that organizations pay to rent space monthly. However, the term public can be misleading.
Even though the cloud might be public, that doesn’t mean that other companies can access another’s information and data. It’s still isolated and protected, but the infrastructure to host that cloud is outside of the company.
A perfect example of a public cloud is INDATA’s iPM Cloud. This cloud-based investment technology has a private-cloud architecture and is secure, private, and scalable. Investment managers can access this cloud anywhere while also alleviating resources from the IT, technology, and security teams. (Note: INDATA offers both private and public cloud options.)
Private vs. Public Cloud Benefits
Whether to go with a public cloud or private cloud provider will depend on the size of the company, its resources, and the infrastructure to support a cloud. Some don’t have the resources to manage it, and a public cloud is the best option. Some might choose to have both, using the public cloud as a backup in case the private cloud fails.
There are advantages and disadvantages to each option. Below, we’ll look more at some of these pros and cons.
Public Cloud
A public cloud provider costs less upfront than a private cloud would. Many providers offer a subscription model with flexible and customizable solutions. A public cloud also helps to save money on the resources needed for a private cloud, such as staff and infrastructure, making public clouds more scalable.
Cloud storage is virtually unlimited, and companies can upgrade to more storage if needed. However, with a private cloud, the scalability will largely depend on how many resources are available in-house. If companies are already using a back-office managed service, they might not have the resources to manage a private cloud either.
One of the disadvantages of a public cloud is less control over security. Security and compliance broadly fall on the provider, so for investment management, which is subject to compliance and stricter regulations, a private cloud might be a better option.
Private Cloud
With private cloud providers, businesses can fully control the cloud for their data. The private cloud could also perform faster since it is not a shared resource.
Additionally, while public clouds do provide some level of flexibility, private clouds are the most flexible option. Businesses can create the perfect private cloud solutions that fit their needs and can update these clouds as their needs change.
However, with a private cloud, finding the absolute perfect fit might be difficult if companies are looking for something specific. It can also be more challenging to access the data from anywhere. A private cloud is accessible via the internet, making it available to anyone in the company.
How InData iPM Supports Both Cloud Deployment Models
iPM Cloud is a private cloud-based hosting service. It’s a turnkey solution designed for SaaS (software as a service) solutions. This proprietary model combines the nimbleness of a public cloud with the security of a private cloud. It’s a hybrid that delivers the benefits of public and private clouds.
Cloud Migration Best Practices for Financial Firms
Organizations ready to migrate can follow this advice:
- Work with the provider to understand how data and applications will flow to the cloud.
- Establish governance and compliance guidelines.
- Adopt a hybrid cloud infrastructure to get the best of public and private hosting.
- Run data validation tests.
- Consider a phased migration approach for less disruption.
- Perform risk management reviews.
- Deliver training and upskilling to team members.
The Future of Public and Private Cloud
As more companies look to do more with less, hosting private clouds may become less popular. They can be challenging for businesses that want to save resources, cut costs, and scale. However, the need to consider a private cloud vs. public cloud will continue as companies assess what makes sense for them.
Artificial intelligence (AI) also promises exciting innovation for public cloud technology. Generative AI allows public clouds to process data in real time, offering companies valuable insights. Now is the time for companies to find a public cloud solution that works for them.

FAQs
What is the difference between a private cloud and a public cloud?
Public clouds are shared, third-party hosting environments. They are lower cost and easier to scale. Private clouds are dedicated, single-tenant solutions that provide the greatest security and customization.
When should an investment firm choose a private cloud over a public cloud?
Firms that seek complete control and have more money to invest should opt for private clouds. Those with fewer resources and a desire to be more flexible should select public clouds.
What advantages do public cloud providers offer for firms with variable workloads?
Public clouds offer elasticity, which means they can scale up or down as demand fluctuates. It’s a pay-as-you-go subscription mode that adapts to a firm’s specific needs.
Are there drawbacks to using public cloud models for sensitive financial data?
Firms have less control with public clouds, and the security may be less robust than a private cloud. Organizations must solely depend on their provider for a reliable cloud.
Can a hybrid cloud solution combine the benefits of both private and public clouds for investment firms?
Yes, a hybrid cloud offers the best of both worlds. This solution delivers the flexibility of a public cloud with the security of a private cloud.
