Public Cloud What is Public Cloud?
Public cloud is a form of cloud computing that involves third-party to own, host, operates and manage servers, storage, and apps for the public. Users pay as they go for these resources, reducing upfront infrastructure investment. Scalable, flexible, and cost-effective public cloud services allow enterprises to easily scale IT resources on demand. Public cloud users are relieved of maintenance, security, and updates as it executed public cloud providers.

- Global spending on public cloud services is projected to reach $679 billion in 2024 and surpass $1 trillion by 2027.
- By 2028, over 50% of enterprises are expected to use industry cloud platforms to accelerate business initiatives.
- Cloud's role in 2028 will shift from a technology platform to a business necessity.
- Organizations are investing in cloud technology to foster innovation, create market disruptions, and enhance customer retention.
What are the difference between public cloud vs. private cloud vs. hybrid cloud?
| Features | Public cloud | Private cloud | Hybrid cloud |
|---|---|---|---|
| Ownership and management | Owned and operated by third-party cloud service provider. | Owned and operated by a single organization, either on-premises or by a third-party provider exclusively for that organization. | Combines elements of both public and private clouds, allowing data and applications to be shared between them. |
| Accessibility | Accessible over the internet, providing global availability and scalability. | Accessible via a private network, providing enhanced security and control over data. | Provides the flexibility to use both public and private resources based on specific needs and workload characteristics. |
| Cost structure | Typically follows a pay-as-you-go or subscription-based pricing model, eliminating upfront hardware costs. | Involves higher upfront costs due to infrastructure investment but may lead to lower operational costs over time. | Offers a mix of pay-as-you-go and upfront investment, providing cost and budget flexibility. |
| Scalability | Offers on-demand scalability, allowing users to easily scale resources up or down based on requirements. | Offers scalability, but expansion may require additional infrastructure investment. | Enables dynamic scaling by utilizing public cloud resources for variable workloads while maintaining sensitive data on the private cloud. |
| Resource sharing | Resources are shared among multiple users (multi-tenancy model), promoting cost efficiency. | Resources are dedicated to a single organization, ensuring more control and customization. | Combines the benefits of public cloud efficiency and private cloud customization, allowing for a tailored approach to resource allocation. |
| Security and compliance | Security measures are implemented by the provider, and compliance is often addressed through certifications. | Organizations have greater control over security measures, allowing for customization based on specific compliance requirements. | Security measures vary based on the chosen combination, allowing organizations to meet specific compliance requirements. |
What are the differences between public cloud services and on-site IT infrastructure?
Understanding the differences between public cloud services and on-site IT infrastructure is crucial when contemplating cloud computing.
| Public cloud | Typical on-site IT infrastructure |
|---|---|
| Resources are hosted and managed by third-party providers. | Resources are hosted and managed within the organization's premises. |
| Scalability is dynamic, allowing for easy resource scaling based on demand. | Scalability often requires upfront investment in hardware and may be limited by physical constraints. |
| Pay-as-you-go pricing model where users pay for resources consumed. | Capital expenditure is required for hardware purchases, with ongoing operational costs for maintenance and upgrades. |
| Offers greater flexibility and accessibility, enabling remote access from anywhere with an internet connection. | Accessibility may be limited to on-site or via VPN, restricting remote access. |
| Provides redundancy and high availability through distributed data centers. | Relies on local backups and failover systems for redundancy, which may be less robust. |
| Security measures are managed by the cloud provider, often with advanced security features. | Security measures are managed internally, requiring dedicated resources and expertise. |
