From an innovative storage solutions to hosting robust applications, cloud has become the operating standard for the enterprises. The question is no longer whether you want to trust your operations to a cloud architecture but which type of cloud infrastructure is best for your business: public, private, or a hybrid mixture of both.
To select the right cloud deployment method, you need to map out basic applications i.e. web service delivery to the cloud and compare on the benefits such as cost, reliability, flexibility and computing power.
In this blog, we will discuss the use-cases and compare on all the major criteria to help your business make the right decision.
Public cloud services
A public cloud solution is what most people think of when considering cloud architecture. With this model, a third party provides storage, application hosting, and other resources to individual and organizational users via the internet.
Because public clouds include shared resources, companies are able to leverage their providers’ high-capacity computing power and bandwidth capabilities. It also means they can scale up capacity during peak times.
The sharing inherent in public clouds can lead to security and privacy concerns because users have no control over how their providers implement cloud security.
Cost and maintenance
Public clouds are the least expensive to set up because the provider pays for the hardware, hosting, and bandwidth in a pay-for-use model. The provider is also responsible for managing these resources.
Public cloud users have no control over how their providers maintain the integrity of their data. Because of the shared storage resources, any corruption event can affect all computers sharing the database. Therefore, they need to put your trust in their providers, so choose wisely.
Availability across different regions
Public cloud users can access resources from anywhere with a computing device and access to the internet.
Public Cloud Use-cases
Public cloud models are best-suited for IT executives in small- to medium-sized businesses in industries without heavy regulations. They’re appropriate for standard enterprise applications many users access, software development processes that require collaboration, software as a service (SaaS) solutions, and other applications that don’t involve highly sensitive data.
Private cloud services
In a private cloud infrastructure, a private network hosts services and infrastructure, often for a single enterprise. Access is restricted to specified clients rather than publicly accessible. Private cloud services are similar to on-premises data centers users access through virtualization technologies. The organization owns and manages the infrastructure or contracts these services through a third-party vendor under their direction.
Computing, storage, and networking resources are dedicated to a single organization, so IT leaders have control over resources. However, they have access to a limited supply matched to their demand. They are not leveraging the power of shared resources.
Private clouds offer the highest levels of security because access is limited to the organization’s private network, and they have more specific security controls than public clouds.
Cost and maintenance
Private clouds are less cost-efficient. Users pay for resources dedicated solely to their network users, and they have to pay to keep them updated. They or their private cloud providers are responsible setting up and maintaining their private cloud infrastructures.
Private clouds share databases only within each infrastructure’s private network, so less chance of data corruption exists. When a corruption event occurs, it stays within the organization.
Availability across different regions
Although each private cloud is dedicated to one organization, each organization can distribute information across many company locations via the network. Private cloud services provide high availability and redundancy because organizations can reallocate all resources in the event of a failure.
Private Cloud Use-cases
Private cloud services are best-suited to businesses that revolve around proprietary data or those that process and store private data or carry out sensitive tasks. Good candidates include financial institutions, eCommerce companies, and health care providers. Internal business operations are often run on private clouds.
Hybrid cloud services
The above parameters provide guidelines for IT leaders to choose which type of cloud solution is their best option.
However, choosing a public over private cloud solution or vice-versa often doesn’t make sense, especially for those whose businesses are or are becoming more complex.
IT decision-makers may want to take advantage of public cloud architecture efficiency and cost savings for standard enterprise applications that many users access. On the other hand, they might also own a lot of confidential information that requires more secure handling.
In these situations, hybrid solutions may be the answer. A hybrid solution mixes and matches services — often from different providers — to support necessary applications, data, and infrastructure in the most cost-effective and efficient way possible in accordance with company structure and business requirements.

According to Gartner, most of the medium and large organizations are moving towards a Hybrid Cloud or Multi-Cloud strategy that is something to consider for any business which is dealing with complex data and needs high availability across all regions.
For applications such as Netflix, where high speed and high availability are critical, a hybrid solution can ensure high availability and fast content delivery — but also provide high security for customers’ private data.
Many believe choosing among hybrid, public, and private cloud services is basically a trade-off between cost efficiency and security.
However, if you exercise due diligence and implement security best practices, your data, applications, and computing environment can be safe and secure no matter which solution you choose, leaving you free to select the best model based on your organizational infrastructure and operational priorities.
