Security differences between public and private clouds

A private cloud is indeed the ultimate goal of a virtual datacenter. First you can take your physical servers and turn them into virtual servers to reduce hardware costs and increase flexibility. If you are smart, you can also add tools such as deep security to optimize your safety status. Then, when the hardware fails, you will see a strong resilience through shared storage and a virtual server moving from one host to another. Eventually you may see the capacity is full, you need to start an extra server for a specific task, and keep the other servers dormant depending on the day or year of work (think about the holiday rush or the closing period of the financial quarter). You may even have to go all the way to the data center to make it work to provide redundancy, scalability, and performance. Because smart homeowner receptacle we've been working this way for a while. In doing so, we have learned a great deal from ourselves, and we can impart these experiences to our customers and shape our products. However, there is a common factor in all of these stages-you are in a private cloud. You can still filter everything by erecting a wall around your pool of resources, blocking out the bad guys. The mobile phone encyclopedia's servers are not protected by strong perimeter, but will be on the same side as strangers, competitors, and the inevitable same organized criminals, and they are the ones who are today who are doing everything you can to keep out of the data center--the only way into the public cloud, Your supplier runs the same thing as the final private cloud mentioned above, and they can give you a small piece of it, billed as a usage, very similar to your own personal cloud. But there's a big difference. Your obstacle is a bunch of credit card numbers (stolen or otherwise)! So how do you guard against them?
　　
Protecting cloud security means that hosts must defend themselves. Self-defense at the front end is because the firewall rules may be inadequate and may be attacked by threats from within the firewall. Protect your data at the back end because there are many strangers sharing the same storage space with you, and the so-called security module, which your cloud provider offers to "believe our system will not be hacked", has proved to be the weakest again and again. Can you really? Can a host really protect itself in a public environment and be safe enough to comply with the cloud environment? We believe that it can, and also believe that we have a cornerstone in the future to enhance the security of the public cloud. The security of the cloud is now available (Deep Security7.0), and more features are continuing to be developed.
