Learn now about secure VPCS in the cloud

With the advent of the cloud era, the network scale continues to expand, ARM hostingand security problems such as ARP spoofing, broadcast storm, and host scanning become increasingly serious. To solve these problems, network isolation technologies such as virtual private cloud (VPC) have emerged. What is a VPC? What does it do? How do I use it? The following parsing will let you know the result in seconds.

What is a VPC?

Virtual Private Cloud (VPC) is the full name of a virtual private cloud. Cloud platfrom providerIt builds an isolated virtual network environment for the elastic cloud server (ECS), which is configured and managed by users themselves, improves the security of user resources on the cloud, and simplifies the network deployment of users. You can define network features, such as security groups, IP address segments, and bandwidth. In a VPC, you can easily manage and configure internal networks to quickly and securely change networks. In addition, users can customize ECS access rules within and between security groups to enhance ECS security protection.

A virtual private cloud (VPC) creates a logically isolated virtual enterprise network development space for users. virtual private cloudUsers can use one of these resources more conveniently, just like using a private cloud.

What does VPC do?

Now that you know the basic definition of a VPC, let's take a look at how to use a VPC through an architecture diagram.

When you look at this picture, you might wonder. What are network ACLs and security Groups? What's the difference? Let's start with the security group. A security group is a logical group of ECS that have the same security requirements in a region. The binding of security groups and ECS can achieve the same function as a firewall. By default, instances of different security groups are not connected, but they can authorize mutual access between the two security groups.

A network ACL is a security protection policy similar to a security group. If you want to add other security layers, you can enable this policy. Network ACLs protect subnets. It controls the flow of data to and from the subnet through the direction and entry direction rules associated with the subnet. The security group has only one permission policy, but the network ACL can deny and allow.

In fact, VPCS are like our circle of friends. Not only can you set "don't look", but also set "don't let it see my circle of friends" to achieve flexible Settings.
