云服务器ecs和vps

1. Supply and deployment time: VPS is instant and does not require the installation of an operating system. Cloud hosting is also instant and can be completed in a few minutes. It can be deployed with one click or the operating system can be installed independently.
2. Security and reliability: VPS has poor security. Program defects, ARP spoofing, viruses, resource congestion, etc. installed on other VPS on the same physical server will seriously affect itself; it basically has no ARP, Trojan and DDOS prevention capabilities. . The cloud host has high security and built-in ARP protection, which improves DDOS attack prevention capabilities on a large scale; it shares the performance and reliability of brand enterprise-level servers and hardware virtualization, and has built-in HA; it provides a variety of rapid recovery measures such as backup machines, snapshots, and data backups. .
3. Performance and guarantee: VPS has poor performance and guarantee, average performance, and is only suitable for small-scale concurrent access; performance is not guaranteed and is easily squeezed by other VPS on the same physical server. Cloud host performance and guarantee are good and guaranteed; same as physical server.
4. Flexibility and scalability: VPS expands quickly and is subject to the configuration of a single server; cloud hosts are instantly supplied and expanded on demand, without paying for original leased resources.
5. Cost of ownership: VPS with low configuration has the lowest rental price, but low security reliability and unguaranteed performance lead to unguaranteed service quality and difficult to control and high operating costs. The cloud host has the lowest comprehensive cost, no monthly deposit, pay-as-you-go usage, and basically zero maintenance. It can also share the cost advantages brought by large-scale, green energy-saving, and best IT practices.
6. Ease of use and management: VPS provides a single stand-alone management interface without root or super administrator operating system permissions, and management flexibility is limited by the management interface. The cloud host has built-in KVM, and customers can centrally and uniformly manage cloud hosts distributed in various places through the self-service system; they have full root or super administrator operating system permissions.

Is cloud server or vps better? Cloud server is a simple, efficient and elastically scalable computing service. Users can automatically adjust computing resources according to business needs and scaling strategies. VPS is a dedicated server space service divided from the server. It does not represent the entire server, but only a part of it with some functions. Let’s introduce the difference between cloud server and vps to see whether cloud server or vps is better.
Physical architecture support
The bottom layer of the true cloud host is composed of large-scale server clusters, forming a massive computing, storage, and network resource pool in the cloud, which is allocated according to user needs. How much, thus forming an efficient use of resources.
VPS is provided by an independent physical server. If a hardware failure occurs, it cannot be automatically repaired.
Data Storage
Cloud servers are deployed in cloud resource pools built by a large number of server clusters. It is network-based distributed data storage with no single point of failure. Supports rapid reconstruction of different nodes. Even if the computing node is abnormally interrupted or damaged, the virtual machine can be rebuilt on other nodes in a very short time without affecting data integrity.
All data of the vps host is stored in the local hard disk of a single server and cannot be deployed in a distributed manner. Therefore, it will always face the risk of machine hardware failure. Once a hardware failure occurs, it cannot automatically and quickly recover.
Data Backup
Cloud server rental supports snapshot backup strategy, which can write multiple copies of data in real time. Even if user data is lost or accidentally deleted, backup and restoration can be quickly scheduled online. , which is unmatched by traditional backup methods.
It is difficult for vps to provide real-time snapshot backup function. The most common method is for the administrator to export the backup data, repair it and then re-import it.
Hot migration capability
Cloud computing servers support hot migration. Even if a certain underlying server hardware fails, user services can be migrated online to other cloud servers without affecting the migration process. The website is functioning normally. This is something that fake clouds cannot do.
Once a vps hardware failure such as hard drive damage occurs, the data backup can only be manually transferred to other servers to resume work, and only after you complete the migration work can your website resume normal access.
From the above differences, cloud servers have superior performance and higher security than vps! Now vps products are gradually being replaced by cloud server products. If you don't know whether to choose cloud server or vps, it is recommended to choose cloud server.
