Differences between the VOS System and Traditional Operating Systems

The VOS system (Virtual Operating System) is a special type of operating system that allows multiple isolated operating system instances to run simultaneously on a single physical hardware. This system is usually used in virtualized environments, such as cloud service providers or enterprise data centers, to improve resource utilization and flexibility.

• Resource Allocation: The VOS system is usually created on a shared server and shares resources (such as CPU, memory, and storage) with other virtual machines. In contrast, traditional operating systems usually run on physical machines with independent hardware resources and do not share resources with other systems.

• Operating System Compatibility: The VOS system can run on different operating systems, such as Linux and Windows. However, traditional operating systems usually run only one operating system.

• Security: Since the VOS system shares resources, it may face higher security risks, such as being attacked by other virtual machines or being invaded by attackers exploiting vulnerabilities. Traditional systems have relatively higher security because they have independent hardware and operating systems.

• Maintenance and Management: The maintenance and management of the VOS system are usually more complex because it is necessary to manage multiple operating system instances. In contrast, the maintenance and management of traditional systems are relatively simple, and only a single operating system needs to be focused on.

• Performance Impact: The VOS system may have a certain impact on performance because resources need to be allocated among multiple virtual machines. Traditional systems usually can provide more stable and consistent performance.

• Application Scenarios: The VOS system is suitable for environments that require efficient use of resources and support for multiple operating systems and applications, such as cloud computing, big data analysis, and high-performance computing. Traditional operating systems are suitable for occasions with higher requirements for performance and stability, such as desktop computing and embedded systems.

In summary, there are significant differences between the VOS system and traditional operating systems in terms of resource allocation, compatibility, security, maintenance and management, performance impact, and application scenarios. The choice of which type of operating system depends on specific business needs and technical environments.

The Role and Functions of the VOS System in Cloud Computing Centers

The VOS system plays an important role in cloud computing centers and is mainly responsible for the following functions:

• Resource Upload Management: The VOS system is mainly used to help clients upload objects to cloud storage. It supports dual-site active-active, that is, in the event of a single-site failure, it can automatically switch domain names to achieve dual-site active-active. This means that during the upload process, if Alibaba Cloud's OSS service fails, the system will automatically switch to Tencent's COS service for upload to ensure the security and stability of data.

• High Availability Guarantee: The VOS system realizes read high availability and write high availability through dual-site mutual backup and automatic switching. For read requests, if 4xx or 5xx errors are encountered, the client SDK will automatically switch to the standby domain name to ensure the high availability of read requests. For write requests, the VOS system will automatically select available cloud vendors to upload files. If it is found that the service of a certain cloud vendor is unavailable, it will automatically switch to another cloud vendor to ensure the high availability of write requests.

• Disaster Recovery Scheme: The VOS system provides disaster recovery schemes, including read high availability and write high availability. Read high availability is achieved through dual-site mutual backup and automatic switching, and write high availability is achieved through automatic selection of available cloud vendors. Such a design enables the system to respond quickly in the face of unexpected situations and ensure the continuity of services and the security of data.

• Resource Type Support: The VOS system supports the upload of multiple resource types, including but not limited to pictures, audio and video, text, etc. Each resource type has its own two domain names, corresponding to different cloud storage services respectively, ensuring the diversity and flexibility of resources.

• Overall Process Management: The VOS system provides a complete resource upload process management, including the user side requesting the AccessToken, the business service side obtaining the AccessToken, the user side uploading resources, the business service side confirming the successful upload, the business service side obtaining the object URL, and performing subsequent processing. This process ensures the smooth progress of resource upload and the accurate transmission of data.

In summary, the role of the VOS system in cloud computing centers is mainly reflected in resource upload management, high availability guarantee, disaster recovery scheme, resource type support, and overall process management, providing stable, efficient, and secure services for cloud computing centers.
