SaaS delivers software applications over the internet on a subscription basis. Users can access these applications via web browsers. Popular SaaS applications include Google Workspace, Salesforce, and Microsoft Office 365.
Cloud Deployment Models
Public Cloud
Public clouds are owned and operated by third-party cloud service providers, delivering their computing resources over the internet. Users share the same infrastructure and resources with other tenants, leading to cost efficiency.
Private Cloud
A private cloud is used exclusively by a single organization. It can be hosted on-premises or by a third-party provider. It offers enhanced security and control, making it ideal for sensitive data.
Hybrid Cloud
Hybrid clouds combine public and private clouds, allowing data and applications to be shared between them. This model provides greater flexibility and optimization of existing infrastructure, security, and compliance.
Multi-Cloud
Multi-cloud involves using multiple cloud services from different providers to minimize the risk of data loss and downtime. It enhances performance by leveraging the strengths of various providers.
