How do enterprise users choose the configuration of virtual machines?

In fact, the birth of cloud hosting has gradually developed from the server, and its use has also done a lot of technical challenges, so cloud hosting is so popular with enterprises. In China, Alibaba Cloud, Tencent Cloud, Cloud, Yimai Cloud, etc. are available for enterprises to choose from. (For example:.)

Yimai Cloud launched a permanent activity for enterprises to purchase cloud servers for 0 yuan).

The main thing about cloud hosting is stable performance, reliable hardware, no need to worry about maintaining hardware, and the hardware configuration of the host can also be freely upgraded or replaced.

Cloud services refer to the on-demand and easily scalable access to required services over the network. This kind of service can be related to IT and software, the Internet, or other services, which means that computing power can also be circulated through the Internet as a commodity.

Cloud services allow users to store and read data over the Internet. By breeding a large number of start-ups, we provide a wealth of personalized products to meet the ever-expanding personalized needs in the market. Its breeding method is to provide startups with a complete set of services such as capital, promotion, payment, logistics, and customer service, and let their own operational capabilities be used externally on demand like water and electricity.

This is the business model of cloud services.

Lu En's rate is absolutely forced to lose Ejiao, and I'm afraid that I'm hungry.

It depends on what you use it for ** or what you do it for. If you are doing a personal blog or a small **, 1 core 1G and 1 core 2G are enough. If you are doing enterprise **, 2 cores and 4G are enough.

For applications with frequent computing, choose a computing server with a high-frequency CPU.

For applications that frequently read and write hard disks, high-speed and large-capacity disks are configured with IO optimization.

Now the choice of cloud servers is actually very wide, The specific depends on the type of business, most of them should provide ** services, I am actually a novice in this regard, talk about personal experience, first on the picture.

Directly use wamp + wordpress to do, simple and trouble-free, after going online, the speed is also passable, chrom check is also in about 2 seconds, and then it doesn't work, now the page is basically in 5-7 seconds, log in to the server to view, the CPU has been running full, but the real access is not high, recently trying to solve this problem, it may also be a hardware bottleneck, the above picture is a 3-day resource request log, Personally, I think that this configuration should be able to meet the basic business needs, but it is not possible to upgrade the configuration or migrate to Alibaba Cloud, our company's station is in Alibaba, the configuration of the choice is not as high as this, but there is no problem in this regard, it may also be that the official website of the enterprise is relatively simple, purely personal experience, I hope to give you a reference.

How to purchase and configure an Alibaba Cloud server?

It is recommended to start with a low configuration, so that you can measure the server resources in the later upgrade.

Isn't this based on your own needs ...

The ECS configuration has the following parameters: 1. CPU; 2. a memory; 3. a hard disk; 4. Bandwidth; 5. Lines.

cpuIt refers to the core computing power of the cloud server configuration, and the number of cores refers to the number of processors contained in the CPU, so that multiple processors can share the cache within the CPU, which can greatly speed up the speed. If the CPU is large and has many dynamic pages, it is recommended to select a multi-core CPU.

MemoryIt is a transit station for data, and it is also an important factor in determining the speed of opening, the larger the memory, the larger the available cache, and the faster the opening speed. Choose the appropriate configuration space according to the scale of your **, if it is a general personal blog, or a corporate display**class, you can choose a smaller one, if it is**class, the news class should be a relatively large space.

Hard diskIt is the place where the data is stored, and the size of the hard disk should be determined according to the size of the data, and the remaining space should be taken into account when choosing. In addition, the read speed of the hard disk directly determines the speed of file reading, and the read speed of the cloud server hard disk is much faster than that of other **, which is generally enough.

LinesThe choice is sometimes very difficult for us. If we were targeting local users, then we could have chosen a server in a single-line computer room, but for the whole country, we could only choose a server in a BGP computer room, such as Jing'an Zhengzhou BGP computer room.

If you are a small individual** and have a small number of visits, then you can choose a low-configuration ECS that can temporarily meet your requirements (usually 1 core and 1 GB). For e-commerce types**, it is recommended to have at least 2 cores and 4G cores. With the development of the following **, you can also upgrade the configuration at any time, which is also the advantage of cloud servers.

Of course, if you want to run and access faster, you can increase the configuration appropriately.

For example, for scenarios that require massive data storage and offline computing, such as Hadoop distributed computing, massive log processing, and large-scale data warehouses, you can select the Alibaba Cloud Server (ECS) big data instance family. Big data instance families are suitable for customers in industries that require big data computing, storage, and analysis, such as the Internet and financial industries.

For AI applications such as machine learning and deep learning, you can purchase GPU compute instances to build AI applications based on the TensorFlow framework. GPU computing ECSs are suitable for thin terminal scenarios, such as graphics processing, cloud real-time rendering for cloud games, and real-time cloud rendering for AR VR.

The choice of cloud server configuration is mainly judged according to the program you need to run, as well as the type of your ** and the number of visitors, if so. NET program, 8 cores and 8G or higher are recommended.

If you use **, you can choose the configuration according to the traffic rate.

Let's start with the low, this can be flexibly expanded.

The third applicable scenario: For backend servers of small and medium-sized databases, data processing, cache clusters, and other enterprise applications, it is recommended to select an ECS with about 6-8 cores.

1. Change the username and password.

2. Configure the disk partition of the virtual machine.

Remote Access Port Modification .

4. Window system firewall security configuration.

Use remote desktop connection to log in to the virtual machine: use the Windows key (Windows logo) + R on the keyboard to pop up the run dialog box, enter the command mstsc in the dialog box or enter the start-program(p)-accessories-remote desktop connection, and then fill in the IP address of the virtual machine in the input box behind the computer. Then enter the username and password automatically assigned by the system on the login box interface to log in successfully.

1. Change the username and password.

Right-click My Computer-Management, and then in the pop-up computer management interface, click "Local Users and Groups" on the right side to find the username you used to log in, right-click - Set Password to set a new password for the user name, if you modify the user name, you can right-click - Rename to modify.

2. Disk management.

Right-click My Computer - Management, and then in the pop-up computer management interface, click on the black color on the right side of "Disk Management" to represent the assigned disk space Right-click on the black unassigned disk - New Disk Partition - New Disk Partition Wizard - Select the main disk partition (size is set according to your needs) - Assign a disk drive letter - Perform a quick format - Done.

Change the volume label of the drive letter - Right-click on the drive letter - Change the drive letter and path - Assign the drive letter.

3. Change the 3389 remote login port.

The default remote login port of Windows is 3389, and sometimes the remote port needs to be changed for security reasons. Click Start-Run-Enter regedit to open the registry, because there is a lot of information on the registry, the easiest way is to find the place where you need to modify the port, keyboard Ctrl+F, pop up the search box, enter the portnumber to find, you may find several options, pay attention to the name of the search value of 3389.

There are two places that need to be modified - double-click on the portnumber, select decimal, and change 3389 to another number, preferably the bigger the better, of course, within 65535, because the large number is less likely to be occupied by other programs.

4. Firewall security configuration.

After the modification is completed, be sure to check whether the local firewall is turned on, if it is turned on, you need to add the modified port to the exception in the firewall. Right-click on the network neighbor - select Properties - Network connection - right-click on the local connection - Properties - Advanced - Settings, open Windows Firewall, select the Exception option:

The name can be filled in according to the requirements, and the port number can be filled in with the previously modified port number, which can be directly confirmed. Once this is done, the server needs to be restarted for the modified port number to take effect. Then, when you log in remotely, you need to add the IP Address: in the Remote Desktop Link Interface-Computer input box

Port Number (Modified Port) - Link.

The cloud host depends on what you need, and you can do low-point configuration in the early stage, and the configuration can be upgraded at any time.

What industry you are using it in depends on the CPU and memory needs, as well as the bandwidth requirements.

According to your own needs, such as what you want to build a website or what you do, what configuration you need, you can customize the configuration and choose the web link.

The advantages of cloud servers are based on cloud computing technology, and compared with independent servers, they have the following characteristics:

1. From the technical aspect: cloud computing technology is used in cloud computing technology, and cloud computing technology integrates various software and hardware technologies such as computing, network, and storage. Dedicated servers, that is, independent, do not integrate these resources.

2. From the security aspect: the cloud server has natural anti-ARP attacks and MAC spoofing, snapshot backup, and data will not be lost permanently. Dedicated servers, on the other hand, don't have this feature;

3. In terms of reliability: cloud servers are based on server clusters, so the hardware redundancy is high and the failure rate is low; Dedicated servers, on the other hand, have less hardware redundancy and a higher failure rate.

4. In terms of flexibility: users can increase their own configuration in real time, and there is a large space for expansion; Dedicated servers, on the other hand, have limitations in this regard, and if you have a new application, you have to buy another one.

5. From the perspective of performance: the cloud server is 4 times the computing power of the same configuration of independent servers, which can meet the requirements of high-performance computing;

6. From the perspective of stability, cloud servers can be automatically migrated due to failures, which means that if a cloud server fails, the applications on it will be automatically migrated to other cloud servers. Dedicated servers don't have this function, and if they do, they will go down.

7. From the perspective of energy saving, the automatic migration technology of cloud servers based on cloud computing means that at night, the utilization rate of physical servers is not high, and the automatic migration technology will concentrate the application on several physical servers, and other physical servers can be dormant, so as to save energy.
