Cloud Computing Services Models
There are four service models in Cloud computing services that are suitable for different scenarios:
Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) is a cloud computing service model that provides basic computing resources, such as virtual machines, storage space, and network bandwidth, charged at a pay-as-you-go model. IaaS usually provides interfaces such as APIs and managed service platforms, which users can manage and allocate their own cloud resources.
Platform as a Service (PaaS)
Platform as a Service (PaaS) provides a platform for application development and operation. Developers can develop and run their own applications on the cloud without worrying about the underlying infrastructure. PaaS usually provides development tools, databases, and network services.
The main advantage of PaaS is that it can accelerate application development, reduce development and operation costs, and improve the scalability and reliability of applications.
Software as a Service (SaaS)
Software as a Service (SaaS) focuses on the permissions to use and access business applications. Users can use these applications over the Internet without installing or maintaining the related software and hardware. SaaS is usually provided by subscription, and users can choose different subscription plans and pay based on usage.
The main advantage of SaaS is that it can reduce software purchase and maintenance costs, improve flexibility and convenience of use, and can automatically adjust services according to business needs.
Backup as a Service (BaaS) and Disaster Recovery as a Service (DRaaS)
Backup as a Service (BaaS) and Disaster Recovery as a Service (DRaaS) are special service models in cloud computing that are specifically designed for data backup and disaster recovery. BaaS is focused on providing storage and management of backup data. Users can back up their data to the cloud over the Internet to ensure data security and reliability. When a cyberattack incident occurs, users can restore their applications and data to ensure business continuity.
For instance, SmartCLOUD™ BRR provided by CITIC Telecom CPC combines Veeam Data Platform's Veeam Backup and Replication™ technology to provide customers with versatile backup and disaster recovery solutions.
