Preface
Today I started the ECS 7-day practical training camp of the Alibaba Cloud University Program. I have a more comprehensive and thorough understanding of ECS, especially the various advantages of ECS compared to traditional physical servers, and then make some notes to record what you have learned ( (There are supplementary content for extracurricular queries)

Traditional server introduction
A traditional server is a physical server, which refers to an independent server, that is, a physically separate server. The composition of a physical server includes a processor, hard disk, memory, system bus, etc., and is similar to a general computer architecture.
Advantages of traditional servers
Since the traditional server exists, it has its role and meaning, and more or less will have its advantages. The advantages are as follows
- High performance (for more money)
- High degree of DIY. You can buy your own hard drive for expansion, etc.
- Private possession. Forever belong to oneself, as long as the situation permits, open when you want to open, close when you want to close
Disadvantages of traditional servers
- Compared with the same configuration cloud server, the price is higher
- Configuration trouble. Need to buy hardware, assemble, configure the operating system, apply for public IP, maintain, etc.
- High availability is low. Compared with cloud servers, it is prone to power outages, hard disk damage, man-made damage, etc.
- It occupies a large area. A traditional server is a machine that is really in your own hands, and it will definitely occupy land
- There is noise and heat dissipation. Traditional servers generate noise and heat during operation
- Maintenance is troublesome. The above shortcomings will bring various maintenance troubles
- Lower security than cloud servers
Introduction to Alibaba Cloud ECS Server
The cloud server ECS (Elastic Compute Service) is an IaaS (Infrastructure as a Service)-level cloud computing service provided by Alibaba Cloud with excellent performance, stability, reliability, and elastic expansion. The cloud server ECS eliminates the pre-preparation for purchasing IT hardware, allowing you to use the server as convenient and efficient as using public resources such as water, electricity, and natural gas, realizing out-of-the-box and elastic scaling of computing resources. Alibaba Cloud ECS continues to provide innovative servers to solve a variety of business needs and help your business development. (From the official website introduction)
Advantages of Alibaba Cloud ECS server
- Pay as you go. Friendly to the temporary need for server testing
- Flexible billing. There will be any configuration you basically want, price flexibility, unlimited
- Highly targeted. Companies can purchase on demand according to company needs (machine learning, data analysis, artificial intelligence, high-performance computing, etc.)
- Cost-effective at the same price, saving most of the various manpower maintenance costs, can have better performance
- Performance optimization of application scenarios. Machine learning, data analysis, artificial intelligence, high-performance computing, video forwarding, etc.
- Many regions. ECS cloud servers are located in many regions and can be used by people in different regions and for different purposes
- Good after-sales. What's wrong with the server
- Many operating systems are covered. Such as Windows, Centos, Ubuntu, Core os, etc.
- There are many instance specifications. There are memory type, computing type, general type, local SSD type, big data type, high frequency type, network enhanced type, etc., which are also improving
- For businesses. Not only for individuals, but also for companies. Launched an exclusive physical machine with large specifications required for an enterprise-level Oracle database
- Simple to buy/operate
- Simple to deploy, up and down on demand, resources can be released at any time when not needed, saving resources
- Stable and reliable. The bottom layer of ECS backs up each piece of data. At the physical level, there is a super-A-level data center, with diesel generator backup energy, black technology for automatic operation and maintenance, and data backup to other physical machines. The network level has cloud shield security protection.
- Continuous improvement of technology
- With cloud computing support, it can be connected with cloud databases, OSS object storage, CDN, computing resources, etc. at the bottom
Disadvantages of Alibaba Cloud ECS server
- One thing to say, for us, there is no shortcoming, the shortcoming is that the server hardware is not really in our hands.
Conclusion
After studying the above notes, I personally feel that when buying a server, if it is not necessary to choose a traditional physical server, you can choose a cloud server. Similar to Alibaba Cloud ECS, it can not only meet business needs, but also facilitate processing.
Alibaba Cloud University plans to accompany more than 2,000 college students to practice and grow on the cloud. Here you can get free cpu resources, and you can also participate in free training camps to improve your practice: https://developer.aliyun.com/adc/student/
