1. Let's start from scratch (popular science)
1.1 Concept
Cloud servers, as the name suggests, use "cloud" to refer to virtualization. A cloud server is a system that uses virtualization technology to divide the resources of a large cluster of physical servers into multiple resources, which can be accessed from a central resource hub at any time. The model is based on on-demand access, purchasing on demand, and charging according to usage, making it more flexible and convenient.
1.2 Comparison with traditional servers
Most of us still understand servers in terms of traditional physical hardware (bare metal servers). However, with the development and demands of the internet, although cloud servers are not fundamentally different from traditional servers, they differ significantly in cost, performance, and usability. A traditional server is like buying a villa; you are responsible for managing and managing all the resources inside. A cloud server, on the other hand, is like buying a room in a house; you only need to pay, and you don't need to worry about anything else.
1.2.1 Advantages and disadvantages
Advantages and disadvantages of cloud servers
Advantage:
Pay-as-you-go pricing keeps costs low.
Flexible configuration, adjustable.
It is user-friendly and requires no maintenance.
It has wide applicability.
Shortcoming:
Shared use may result in performance fluctuations.
There are potential network usage risks (due to inferior service providers).
Using the service for more than 3 years will increase the cost compared to traditional servers (the longer the service period, the more expensive it will be).
Advantages and disadvantages of traditional servers
Advantage:
Exclusive access to resources.
The longer the time limit, the more cost-effective it is.
The risk of using the network is low.
2. Summary
Now that you have a general understanding of cloud servers, you'll know they offer many advantages over traditional servers, but they're not omnipotent. We need to weigh the pros and cons and choose based on our current needs. Selecting the right machine for your specific requirements is paramount. I will be publishing more content and server reviews related to cloud computing in the future.
