Log in to the EC2 server according to the method provided by the official website (recommended for Windows users to use Putty connection) Host: Is the public DNS port for the server: 222. Create the root password and enter the following command:sudo passwd root3.
If you think that the virtual host cannot meet your needs, want more resources, and feel that the whole machine is a waste, the VPs server may also be suitable for you.
In terms of price, the VPs host is between the virtual host and the host lease. The performance of the website is more stable than that of the virtual host. users on the VPs do not compete for
Eduvps is a dedicated to learn and provide a free VPS host, because it is purely personal to provide and focus on the use of learning tests, so even if the application of the Eduvps free VPS, there are not open machine, can not connect VPS host and so on, And most of the VPS host applications have different problems in
VMware requires enterprise customers to continue to use vsphere and renew their enterprise license agreement. Because VMware does not sell hardware, it relies on revenue from licensing, support, and services. That's why you work with AWS. Based on the cooperation agreement, AWS will provide hardware, and VMware will provide software, support, and services.

I personally feel that this platform has poor autonomy, whether it is for customers or carriers. For customers, this platform is a virtual operating system and cannot be set on their own in many aspects. It is typical of Windows virtual memory management, which is not good. For sellers, the operation of this platform is inseparable from the support of swsoft. Of course, small-scale operators do not have enough technical strength to maintain the platform, but they must still be unable to do witho
