What are the differences between shared VMs and ECS

Elastic Compute Service (ECS) and Cloud Virtual Host (ECS)

First of all, what is cloud web hosting? Cloud web hosting is a virtual hosting product, it has higher requirements than traditional web hosting, whether it is in performance or stability and quality are better, it has a high rate, intelligent fault tolerance, genuine system, no backup, and many other advantages, especially suitable for enterprises with higher requirements for running quality.

What is a cloud server? Cloud computing server (also known as cloud server or cloud host) is a host product in the cloud computing service system, which effectively solves the defects of difficult management and weak business scalability in traditional physical hosting and VPS services.

Secondly, what is the difference between cloud web hosting and cloud servers?

Cloud virtual hosting, is a further division from the cloud server, through the virtual hosting management software, the cloud server is divided into 100m, 200m and other models of small space, is the best choice for small and medium-sized enterprises to build a website!

Cloud servers and virtual hosts integrate high-performance servers and high-quality network bandwidth through cloud computing, effectively solving the shortcomings of traditional host rental, such as high ** and uneven service quality. Unlike cloud hosts, cloud virtual hosts run on each member node server of the server cluster at the same time, which means that an identical site can be found on each node server, and the configuration and data of the same site on different node servers are consistent.

Generally, you can use virtual hosting, just use it, and you don't need to use the whole server.

Recommended: Alibaba Cloud Virtual Host - Basic (1024M host, 100M SQL database, Gigabit shared bandwidth), can be ICP filing, 130 yuan per year.

The differences between web hosting and cloud servers are:

Cloud servers can support elastic scaling and pay-as-you-go, while web hosting does not.

The environment needs to be manually configured for the cloud server, and the environment does not need to be configured for the virtual host.

The cloud server is an exclusive resource, and the resources of the virtual host are shared.

The cloud server can be managed by remote desktop, and the virtual host can only be managed by FTP.

Cloud servers

A cloud server is a simple, efficient, secure, reliable, and scalable computing service. The popular understanding is that the cloud server uses a dedicated server and uses the new cloud computing virtualization technology to split the independent server into multiple independent servers. It has the following characteristics:

Elastic expansion, configurable upgrades, pay-as-you-go.

Simple and efficient, no need to purchase machines in advance, out-of-the-box, rapid business deployment.

Independent operating system, isolation of hardware resources + exclusive bandwidth.

Centralized remote management platform + multi-level business backup.

Web Hosting

Web hosting is a technology that divides the resources (system resources, network bandwidth, storage space, etc.) of a server (or a group) into a number of relatively independent "small hosts" according to a certain proportion. Each of these "small hosts" can functionally implement basic Internet services such as www, ftp, mail, etc., just like independent hosts. Generally speaking, the IP virtual host of the web host shares a server is used to store the web pages made by the enterprise, and the enterprise can only upload the made web pages to the web host, and the user can access the enterprise through the domain name.

Web hosting has the following characteristics:

The fees are low and suitable for newbies.

The management is simple, no need to configure the environment, and you can upload the program.

Shared resources, lack of stability.

Elastic Compute Service (ECS) is the lowest level of cloud computing SaaS system.

Elastic Compute Service (ECS) is an IaaS-level cloud computing service with excellent performance, stability, reliability, and elastic scalability provided by Alibaba Cloud. ECS eliminates the need to purchase IT hardware, allowing you to use servers as easily and efficiently as you use public resources such as water, electricity, and natural gas, so that computing resources can be used out of the box.

Alibaba Cloud ECS continues to provide innovative servers to meet a variety of business needs and help your business development. ECS (Elastic Compute Service) is the lowest layer of the three-tier cloud computing system. Typically used as the runtime environment for applications, its most important feature is its elasticity.

Why choose Elastic Compute Service (ECS)?

If you select ECS, you can easily build computing resources with the following features:

1.There is no need to build a self-built computer room, no need to purchase and configure hardware facilities for the shed.

2.Deliver in minutes, quickly deploy applications, and shorten the preparation period.

3.Scattered data centers and BGP data centers that continue to expand around the world.

4.Cost transparency, on-demand use, support to scale resources at any time according to business development, and release excess resources at any time.

5.Heterogeneous computing servers such as GPUs and FPGAs, elastic bare metal servers, and general-purpose x86 architecture servers are provided.

6.You can access other Alibaba Cloud services through the intranet, forming a variety of industry solutions to solve problems and reduce the cost of public network traffic.

7.It provides multiple security solutions such as virtual firewall, role permission control, intranet isolation, anti-virus attack, and traffic monitoring.

8.Provides a performance monitoring framework and a proactive O&M system.

9.Provide industry-standard APIs to improve ease of use and applicability.

1. Different permissions and flexibility

The cloud server has independent IP, memory, hard disk, bandwidth and other resources, and can install various operating systems and configure various operating environments according to needs, which is very powerful in terms of function and stability.

Cloud virtual hosting is a part of the capacity virtualized on the server hard disk, sharing server resources, generally no independent IP and bandwidth, the function is relatively limited, the programs it supports are also configured on the server, and the user cannot self-arguing by configuring the environment and installing software.

Second, the difference between use management

Cloud server: The cloud host gives the user complete control authority over the server operating system, can build multiple **, and can configure the development environment by yourself, generally need to be remotely managed, configure the environment by yourself, and the number of sites and traffic are not limited.

Bluehost is recommended for cloud web hosting, which is located in US data centers, and although it is far away, internal access is not slow. The Linux system environment used by bluehost cloud web hosting also supports a simple and easy-to-use cpanel panel, which is also very simple to operate for novice users, and the specific evaluation can go to the bluehost Chinese guide to see (.

Web hosting is cheap, cloud servers are expensive. \

Stability and security Cloud servers are better.

Generally**virtual hosting is sufficient, if it is more important**, choose a cloud server with better security.

Secondly, most of the virtual hosts provide a website building environment and database that have been built, which is very convenient to build a website.

You need to build all the environments of the cloud server by yourself.

The only important difference is: virtual hosting to prevent waste of resources and prevent being attacked, generally open permissions are less, if the source code is written by yourself The default open permissions are generally enough, if you are using the source code integrated by others on the Internet, many of this kind of source code will automatically call the permission when building, if the required permission is not open, then you have to modify the source code, or find the administrator of the service provider to open the permission, otherwise it can't be built, and the cloud server does not have this problem, But it's troublesome to set up an environment.

Nowadays, many service providers have launched trials, try before buying.

You should be looking at Alibaba Cloud hosting. Cloud hosting and web hosting are two different things.

Virtual machines are independent memory partitions on cluster servers. Hard disk. A virtual server built with bandwidth and other resources.

There is independent IP and bandwidth, you can install various versions of the operating system and configure various ** operating environments according to your needs, and there are remote desktop connections to things. is completely independent.

Virtual hosting, on the other hand, is a part of the storage space that is divided on the server's hard disk, which shares the server's IP and bandwidth. There are no separate resources and a separate operating system. There is no remote desktop function, and usually the ** programs supported by the web host are also assigned by default.

There is no way for the user to configure the environment themselves. The function is relatively simple.

Therefore, compared with the two, cloud hosting is more secure and powerful, but for new users, it is recommended to choose other companies that will be more suitable than Alibaba Cloud. From the activation to the use of Alibaba Cloud virtual machines, users need to operate the whole process by themselves. It can be a bit more difficult for beginners.

If you still don't understand, you can continue to ask me.

ECS is the name of Alibaba Cloud, and is collectively referred to as ECS. It is to put tens of thousands of servers together to form a flexible and variable configuration, like public water, electricity, and natural gas, which can be accessed on demand server resource architecture.

The cloud server has a high degree of freedom, and you can install any software you want by yourself. The premise is to have certain O&M experience.

Cloud web hosting can only install programs, and the integration is very high, and nothing else can be done. Suitable for beginners, easy to learn and quick to use.

How you choose depends on what you need. It is recommended to see the web link.

If you have any questions, just ask.

We recommend that you use an Alibaba Cloud ECS server.

A server is primarily similar to a remote computer capable of architecting services autonomously.

Web hosting is one of the 2g folder space in the server has been configured to use the service at first, for example, the server is a house built by yourself, and the web host is a rented house. The self-built house can be decorated as much as you want, and the layout of the rented house has been fixed, just one room, and novices are recommended to use web hosting.

Used to store ** programs, the space is to divide a space on a server for users to use, the server, you can use a server by yourself, and configure a lot of space for your own website.

In general, the cost performance of the server is higher than the space, and it is easy to configure the environment with one click.

Novices are recommended to use the win system server, which is simple and easy to understand, can be connected to the computer remote desktop, and the operation is the same as the computer.

Install a pagoda software, under the environment configuration, open a space, bind a domain name, open a database, etc., all with the pagoda to complete, simple and easy to understand.

IP is a unified address format provided by the IP protocol, which assigns a logical address to every network and each host on the Internet to mask the difference in physical addresses.

In terms of IP, there are independent IP and shared IP hosts in the space, independent IP hosts are a little more expensive, and sharing is cheaper, and the servers are all independent IPs.

The cost of choosing an independent IP, I personally feel that the cost performance is extremely low, so it is better to choose a server.
