- Cloud Deployment Model functions as a virtual computing environment with a deployment architecture.
- Cloud deployment models offer the ability to scale resources up or down based on demand, providing elasticity not typically available in traditional deployments.
A cloud deployment model refers to the specific configuration of cloud resources and services used to deliver cloud computing. These models determine how cloud services are provided and who has access to them. Choosing the right cloud deployment model depends on an organisation’s specific needs regarding scalability, control, security, and budget. In this blog, we’ll explore the main deployment models and their unique characteristics.
What is a cloud deployment model?
Cloud deployment models define how cloud services are made available to users and how resources are configured. The right model can significantly impact your organisation’s operational efficiency, security posture, and cost structure.
1. Public cloud
Public cloud services are provided over the internet and are accessible to anyone. Leading providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform manage the underlying infrastructure. The public cloud model offers significant cost savings by eliminating the need for upfront hardware investments, allowing users to pay only for the resources they consume. It also provides excellent scalability, enabling organisations to effortlessly adjust their resources based on demand. Additionally, maintenance and upgrades are managed by the cloud provider, freeing users from the burden of these tasks.

2. Private cloud
A private cloud is a dedicated environment for a single organisation. It can be hosted on-premises or by a third-party provider, offering enhanced security and control. The private cloud model offers enhanced security by providing organisations with greater control over their data and security measures, making it ideal for handling sensitive information. It allows for customisation of resources and configurations to align with specific business needs, ensuring that operations can be tailored effectively. Additionally, this model simplifies compliance with regulatory requirements, as organisations can implement the necessary protocols directly within their infrastructure.
3. Hybrid cloud
The hybrid cloud model combines both public and private clouds, allowing data and applications to be shared between them. This model offers greater flexibility and operational efficiency. The hybrid cloud model offers businesses the flexibility to choose where to run their workloads based on specific needs, enabling them to utilise public cloud resources for non-sensitive operations while keeping critical data secure in a private cloud. This approach not only enhances cost efficiency but also allows for quick scalability, as organisations can readily expand their resources in the public cloud when required.
4. Community cloud
A community cloud is a collaborative environment shared by multiple organisations with similar interests or compliance requirements. The community cloud model allows for shared costs among all participating organisations, making it an economical choice. It fosters collaboration within the same industry or sector, enabling organisations to work together more effectively. Additionally, this model is designed to meet the specific regulatory requirements of the community, ensuring both compliance and enhanced security for all users.
