What are the differences between stand-alone servers and cloud servers?
This article uses simple and easy-to-understand examples to introduce the differences between independent servers and Cloud Virtual Machine. The content is very detailed. Interested friends can refer to it for reference. I hope it can help you.
With the continuous development of cloud computing technology, many companies and developers are gradually migrating traditional IT businesses to the cloud to reduce the operating costs of server businesses. Here are the main differences between standalone servers and Cloud Virtual Machine.
Cloud Virtual Machine can provide users with easy-to-match resource combination, better redundancy/fault tolerance capability and service buffer space. Through the online service guarantee provided by Cloud Virtual Machine, enterprises do not need to worry about the deployment, management and maintenance of hardware equipment, further saving funds and realizing efficient use of resources.
safety and stability
Cloud Virtual Machine is a part virtualized by cluster servers. Unless all hosts in the cluster fail, the cloud server cannot be accessed. Therefore, it has good stability and high data availability. Many service providers also provide security services such as ddos protection and virus detection.
Independent servers are completely private to users. If the machine hardware and computer room are stable, the general failure rate is not high, but once a failure occurs, it is difficult to recover the loss. If the enterprise's own technology or management is not in place and effective security precautions cannot be taken, there is also a risk of data loss.
deployment costs
If you use traditional independent servers to host your business, you need to rent or purchase server storage, CPU, memory, network and other IT equipment. You also need to consider the performance pressure during peak hours and subsequent O & M, which is costly.
Cloud Virtual Machine lease supports elastic expansion and flexible payment. It is equipped with low configuration during normal hours. It can also increase computing, storage and network resources at any time during peak hours. Users do not need to invest in infrastructure, bandwidth access, redundant power supply, hard disk backup, etc., nor do they need to be responsible for server network and hardware maintenance, which can greatly reduce operation and maintenance costs.
resource extension
Cloud Virtual Machine provides rich instance specifications (CPU and memory), bandwidth and cloud disk for users to choose from, and supports upgrading at any time to meet various business needs. Users can add their own configuration online in real time, with large expandability and faster resource increase and decrease.
Independent servers are usually configured according to user needs. Due to poor expansion of hardware equipment, enterprises need to have an accurate prediction of their own business, because small configuration may not be enough, and it is a cost to replace equipment in the later stage. If the configuration is too high, it will inevitably cause idle resources, which is undoubtedly a waste.
