The public and private cloud computing models offer businesses different levels of convenience, security, and cost.
As organizations consider their options for adopting cloud-based services, it is essential to understand the benefits and drawbacks offered by each model.
In this article, we will compare the costs associated with public and private clouds so businesses can accurately weigh their options when deciding which service to deploy.
We will examine the average costs associated with maintaining a public or private cloud infrastructure and discuss any additional fees incurred during use.
a. Initial Set Up Costs
Public clouds are generally easier and less expensive to deploy than private clouds.
This is because they don’t require any hardware or software infrastructure.
Instead, a business can simply create an account with a public cloud provider and start using it immediately – for instance, through Platform as a Service (PaaS) models like Amazon Web Services (AWS).
This eliminates the need for upfront investments in servers or capital expenses.
On the other hand, setting up a private cloud usually involves significant IT infrastructure setup costs!
This includes purchasing servers and other equipment, connecting them to existing networks, installing operating systems and applications, etc.
Not to forget ongoing maintenance costs such as patching and system upgrades.
Private cloud deployments also require additional staffing resources to manage day-to-day operations.
b. Operating Costs
When it comes to public clouds, they generally offer a pay-as-you-go model that allows businesses to scale their usage on an as-needed basis.
This means businesses can pay for and use only the needed resources, which helps them keep operating costs low.
On the flip side, private clouds require companies to purchase dedicated hardware and storage equipment upfront to access cloud services.
As such, companies have more fixed costs associated with using a private cloud.
You must cover upfront investment expenses even if you don’t use all the allocated resources.
As if that’s not enough, private clouds typically require organizations to hire additional staff members to manage the infrastructure.
Or outsource IT operations management services from third parties, which is not cheap!
c. Maintenance Costs
This, hands down, goes to the public clouds!
They rely on shared resources and economies of scale that minimize the cost of upkeep.
At the same time, most providers will include software updates and security patches in their service agreements, which can further reduce maintenance costs over time.
Private clouds require more upfront investment, as businesses must purchase or lease hardware and servers along with associated software licenses.
Upkeep costs are also higher due to additional staff needed for system administration and hardware monitoring.
However, private clouds provide a high level of control over data security that may be worth the extra expense for some organizations.
d. Security Costs
As you can guess, security is an important factor as far as the cloud is concerned.
While both solutions offer secure systems, the costs associated with each vary greatly.
Public cloud security measures are often bundled into the cost of services.
This means your organizations can benefit from economies of scale when compared to hosting a private cloud solution.
And it doesn’t stop there.
The provider takes responsibility for protecting servers and infrastructure.
So you don’t need to worry about additional costs for securing data or hiring staff specialized in these areas.
On the other hand, private clouds come at a higher cost, given that you have to invest in hardware, software and personnel required for setup and maintenance.
But you’ll also have more control over your data, meaning you can balance security with cost.
e. Service Level Agreements
SLAs define the resources available for use and any guaranteed performance standards and responsibilities of both parties in a cloud computing agreement.
They help ensure that the customer receives all the services they have purchased while also outlining financial penalties if service levels are not met.
When comparing public versus private cloud costs, factor in the SLA offered by each provider.
They can greatly affect which option is more cost-effective.
Let me explain a bit…
Public cloud providers typically offer a standard SLA with a wide range of services and support at no additional charge.
On the other hand, private cloud providers often have more flexible options available with customizable SLAs that may include premium features or specialized technical support for an added cost.
In summary, there is no clear winner between public cloud and private cloud when it comes to cost comparison.
Both offer a variety of advantages and disadvantages that must be considered before making the final decision.
Understanding how each option will impact your business needs, in the long run, is important.
With careful consideration, businesses can decide which solution best fits their budget and operational requirements.
Public clouds may be the most cost-effective choice if you are just getting into this space since they generally require lower upfront costs than private clouds.
They also provide a more flexible approach for scaling up or down with changing business needs.
Private clouds may better suit larger organizations or those looking to store sensitive information.
Such systems generally offer enhanced security features and greater control over resources than public clouds can provide.
