|
|
| 1 What Is Direct Connect? |
|
|
| Direct Connect allows you to establish a stable, high-speed, low-latency, secure |
| dedicated network connection that connects your on-premises data center to |
| Huawei Cloud. Direct Connect allows you to maximize legacy IT facilities and |
| leverage cloud services to build a flexible, scalable hybrid cloud computing |
| environment. |
|
|
| Figure 1-1 shows how Direct Connect connects an on-premises data center to the |
| cloud. |
|
|
| Figure 1-1 How Direct Connect works |
|
|
| Why Direct Connect? |
|
|
| ● Network quality: Direct Connect allows you to establish a dedicated network |
|
|
| for data transmission, which brings high network performance, low latency, |
| and excellent user experience. |
|
|
| ● |
|
|
| ● |
|
|
| Security: Direct Connect establishes private connectivity between your on- |
| premises data center and the cloud. Data is transmitted over a secure |
| dedicated connection. |
|
|
| Transmission speed: A single connection supports up to 100 Gbit/s of |
| bandwidth. |
|
|
| Components |
|
|
| ● |
|
|
| Connection |
|
|
| A dedicated network connection is established between your on-premises |
| data center and a Direct Connect location over a line you leased from a |
| carrier. You can create a standard connection by yourself or request a hosted |
| connection from a partner. |

| Direct Connect |
| Service Overview |
|
|
| 1 What Is Direct Connect? |
|
|
| – |
|
|
| – |
|
|
| A standard connection has a dedicated port for your exclusive use and |
| can be associated with multiple virtual interfaces. |
|
|
| A hosted connection is created by a carrier (a partner of Huawei Cloud), |
| who allocates VLAN and bandwidth resources for you. When using this |
| type of connections, you share a port with other users, and can create |
| only one virtual interface for a connection. |
|
|
| ● |
|
|
| Virtual gateway |
|
|
| A virtual gateway is a logical gateway for accessing VPCs. A virtual gateway |
| can be associated with only one VPC, and multiple connections can access a |
| VPC through the same virtual gateway. |
|
|
| ● Global DC gateway |
|
|
| A global DC gateway enables your on-premises data center to access VPCs in |
| multiple regions so you can use a single connection to provide high-speed |
| access to cloud compute and storage resources in any region. |
|
|
| A global DC gateway can only be associated with connections terminated at |
| the same Direct Connect location. If there are multiple connections |
| terminated at different Direct Connect locations, you need to create multiple |
| global DC gateways. |
|
|
| ● |
|
|
| Virtual interface |
|
|
| A virtual interface links a connection with one or more virtual gateways, so |
| that your on-premises network can access all the VPCs. |
|
|
| Accessing Direct Connect |
|
|
| The public cloud provides a web-based user interface, the management console, |
| for you to access the Direct Connect service. |
|
|
| ● |
|
|
| ● |
|
|
| If you already have an account, log in to the management console and |
| choose Networking > Direct Connect on the homepage. |
|
|
| If you do not have an account, you can sign up for one by referring to |
| Getting Started. |

| connection. |
|
|
| VPN uses an encrypted |
| communications tunnel to |
| connect a VPC on the cloud |
| to an on-premises data |
| center and sends traffic over |
| the Internet. It is |
| inexpensive, easy to |
| configure, and easy to use. |
| However, VPN connections |
| may be affected by the |
| Internet quality. |
|
|
| Direct Connect provides |
| physical connections |
| between VPCs and data |
| centers. It has the |
| advantages of low latency |
| and is very secure. Direct |
| Connect is a good choice |
| when there are strict |

| Standard Connection |
|
|
| A standard connection provides an exclusive port. You can create standard |
| connections on the management console. To improve reliability, you can create |
| multiple connections terminated at different locations and allow them to serve as |
| backups for each other. If you can select only one carrier due to special |
| requirements, you must configure different physical routes for your connections. |
|
|
| You can choose self-service connections or full-service connections. |
|
|
| ● |
|
|

|
|
| Virtual gateway: A virtual gateway is a logical gateway that enables an on- |
| premises data center to access a VPC over a connection. To enable an on- |
| premises data center to access a VPC over a connection, you can associate the |
| VPC with a virtual gateway. To access other VPCs, you can use VPC Peering or |
| Cloud Connect to connect the VPC your on-premises data center is accessing |
| to these VPCs. |
|

| For details, see Global DC Gateways. |
|
|
| Virtual Interface |
|
|
| A virtual interface is a point of entry for an on-premises data center to access a |
| VPC over a connection. A virtual interface associates a connection with a virtual |
| gateway and connects the virtual gateway to a remote gateway, enabling |
| communications between the on-premises data center and the VPC. |
|
|
| Virtual interfaces support static routing and BGP routing. During the |
| establishment of network connectivity, you can use BGP to connect on-premises |
| data centers to virtual gateways. BGP helps you build a hybrid cloud more |
| efficiently, flexibly, and reliably. |
|
|
| For details, see Virtual Interfaces. |

|
| 6 Security |
|
|
| 6.1 Identity Authentication and Access Control |
|
|
| Identity Authentication |
|
|
| You can use Identity and Access Management (IAM) to control access to your |
| Direct Connect resources. IAM permissions define which actions on your cloud |
| resources are allowed or denied. After creating an IAM user, the administrator |
| needs to add it to a user group and grant the permissions required by Direct |
| Connect to the user group. Then, all users in this group automatically inherit the |
| granted permissions. |
|
|
| For details, see Permissions. |
|
|
| Access Control |
|
|
| A security group is a collection of access control rules for cloud resources, such as |
| cloud servers, containers, and databases, that have the same security protection |
| requirements and that are mutually trusted within a VPC. After a security group is |
| created, you can create various access rules for the security group, and these rules |
| will apply to all cloud resources added to this security group. |
|
|
| Your account automatically comes with a default security group. The default |
| security group allows all outbound traffic, denies all inbound traffic, and allows all |
| traffic between cloud resources in the group. Your cloud resources in this security |
| group can communicate with each other already without adding additional rules. |
| For details about the default security group rules, see Default Security Groups |
| and Security Group Rules. |
|
|
| In addition, Huawei Cloud allows you to manage security groups and security |
| group rules, including |

| Adding cloud resources to or removing cloud resources from security groups |
|
|
| You can define access control rules for a security group. Then ECSs that will be |
| added to this security group will be protected. For details, see Security Group. |
|
|
| 6.2 Auditing and Logging |
|
|
| Cloud Trace Service (CTS) is a log audit service for Huawei Cloud security. It allows |
| you to collect, store, and query cloud resource operation records. You can use |
| these records to perform security analysis, audit compliance, track resource |
| changes, and locate faults. |
|
|
| After CTS is enabled, traces can be generated for operations performed on the |
| Direct Connect console. |
|

|
|
| For details about how to enable and configure CTS, see Enabling CTS. |
|
|
| For details about key operations of Direct Connect, see Key Operations |
| Recorded by CTS. |
|
|
| For details about traces, see Viewing Traces. |
|
|
| 6.3 Monitoring Security Risks |
|
|
| Cloud Eye is a monitoring service provided by Huawei Cloud. It provides |
| capabilities like real-time monitoring, timely alarm reporting, resource groups, and |
| website monitoring. Cloud Eye enables you to keep track of your resource usages |
| and service statuses on the cloud, and quickly respond to exceptions to ensure |
| that services run smoothly. |
|
|
| Monitoring is critical to ensuring the performance, reliability, and availability of |
| Direct Connect. Cloud Eye automatically monitors your connections in real time, |
| collects and displays monitoring data in a convenient, visualized manner, and |
| allows you to manage alarms and notifications, helping you watch your |
| connection performance. |
|
|
| For details about supported metrics and how to create alarm rules, see |
| Monitoring. |
|
|
| 6.4 Certificates |
|
|
| Compliance Certificates |
|
|
| Huawei Cloud services and platforms have obtained various security and |
| compliance certifications from authoritative organizations, such as International |
| Organization for Standardization (ISO). You can download them from the |
| console. |

| 7 Permissions |
|
|
| If you need to assign different permissions to employees in your enterprise to |
| access your Direct Connect resources, Identity and Access Management (IAM) is a |
| good choice for fine-grained permissions management. IAM provides identity |
| authentication, permissions management, and access control, helping you securely |
| access your cloud resources. If your HUAWEI ID does not require IAM for |
| permissions management, you can skip this section. |
|
|
| IAM is a free service. You pay only for the resources in your account. |
|
|
| With IAM, you can control access to specific cloud resources. For example, some |
| software developers in your enterprise need to use Direct Connect but should not |
| be allowed to delete other Direct Connect resources or perform any other high- |
| risk operations. In this scenario, you can create IAM users for the software |
| developers and grant them only the required permissions. |
|
|
| IAM supports role/policy-based authorization and identity policy-based |
| authorization. |
|
|
| The following table describes the differences between the two authorization |
| models. |

| Assigning |

|
|
| To authorize a user, you need |
| to add it to a user group first |
| and then specify the scope of |
| authorization. It is hard to |
| provide fine-grained |
| permissions control using |
| authorization by user groups |
| and a limited number of |
| condition keys. This method is |
| suitable for small- and |
| medium-sized enterprises. |
|
|
| ● Assigning |
| identity |
| policies to |

|
|
| ● Attaching |
| identity |
| policies to |
| principals |
|
|
| You can authorize a user by |
| attaching an identity policy to |
| it. User-specific authorization |
| and a variety of key |
| conditions allow for more |
| fine-grained permissions |
| control. However, this model |
| can be hard to set up. It |
| requires a certain amount of |
| expertise and is suitable for |
| medium- and large-sized |
| enterprises. |
|
|
| Assume that you want to grant IAM users the permission to create ECSs in CN |
| North-Beijing4 and OBS buckets in CN South-Guangzhou. With role/policy-based |
| authorization, the administrator needs to create two custom policies and attach |
| both to the IAM users. With identity policy-based authorization, the administrator |
| only needs to create one custom policy and configure the condition key |
| g:RequestedRegion for the policy, and then attach the policy to the principals or |
| grant the principals the access permissions to the specified regions. Identity policy- |
| based authorization is more flexible than role/policy-based authorization. |
|
|
| Policies and actions in the two authorization models are not interoperable. You are |
| advised to use the role/policy-based authorization model. For details about |
| system-defined permissions, see Role/Policy-based Authorization and Identity |
| Policy-based Authorization. |
|
|
| For more information about IAM, see IAM Service Overview. |

| Role/Policy-based Authorization |
|
|
| 7 Permissions |
|
|
| Direct Connect supports role/policy-based authorization. By default, new IAM |
| users do not have permissions assigned. You need to add a user to one or more |
| groups, and attach permissions policies or roles to these groups. Users inherit |
| permissions from the groups to which they are added and can perform specified |
| operations on cloud services based on the permissions. |
|
|
| Direct Connect is a project-level service deployed and accessed in specific physical |
| regions. When you set Scope to Region-specific projects and select the specified |
| projects (for example, ap-southeast-2) in the specified regions (for example, AP- |
| Bangkok), the users only have permissions for VPCEP resources in the selected |
| projects. If you set Scope to All resources, the users have permissions for VPCEP |
| resources in all region-specific projects. When accessing Direct Connect, the users |
| need to switch to a region where they have been authorized to use this service. |
|
|
| Table 7-2 lists all the system-defined policies for Direct Connect in role/policy- |
| based authorization. System-defined policies in the two authorization models are |
| not interoperable. |

|
|
| 10 Basic Concepts |
|
|
| Connection |
|
|
| A connection is a dedicated channel that connects your on-premises data center |
| to the cloud. Connections are more stable, reliable, and secure than Internet-based |
| connections, and provide up to 100 Gbit/s of bandwidth. Direct Connect provides |
| ports only. After you request a connection, you need to work with the carrier and |
| Huawei Cloud to establish network connectivity between your on-premises data |
| center and the cloud. |
|
|
| Direct Connect provides standard connections and hosted connections. |
|
|
| ● |
|
|
| Standard connection: A standard connection provides an exclusive port. You |
| can create standard connections on the management console. To improve |
| reliability, you can create multiple connections terminated at different |
| locations and allow them to serve as backups for each other. |
|
|
| You can choose self-service connections or full-service connections. |
|
|
| – |
|
|
| – |
|
|
| Self-service connection: Huawei Cloud only provides the port. You need to |
| create a connection on the console, and lease a line from a carrier. |
|
|
| Full-service connection: You only need to create a connection on the |
| console, and Huawei Cloud will complete all operations required for |
| network connectivity. |
|
|
| Figure 10-1 shows an example of how standard connections work. |

| Direct Connect |
| Service Overview |
|
|
| 10 Basic Concepts |
|
|
| ● Hosted connection: If you use a hosted connection to access the cloud, the |
| port you use is shared with other users. These connections are created by a |
| carrier (a partner of Huawei Cloud), who allocates the required VLAN and |
| bandwidth for your connection. Only one virtual interface can be associated |
| with each hosted connection. |
|
|
| If you are a partner, you can request operations connections. If you are a |
| common user, you can purchase a host connection from your partner. Hosted |
| connections must be hosted on operations connections, and your partner will |
| allocate VLAN and bandwidth resources to the connection. |
|
|
| Figure 10-2 shows an example of how hosted connections work. |
|
|
| Figure 10-2 Accessing the cloud using hosted connections |
|
|
| Connections support redundant configuration. If there are two connections |
| terminated at different locations in the same region, they can work in an active/ |
| standby pair to back each other up. If one connection becomes faulty, the other |
| will take over, ensuring stable services. |
|
|
| Virtual Gateway |
|
|
| A virtual gateway is a logical gateway that enables an on-premises data center |
| to access a VPC over a connection. To enable an on-premises data center to access |
| a VPC over a connection, you can associate the VPC with a virtual gateway. To |
| access other VPCs, you can use VPC Peering or Cloud Connect to connect the VPC |
| your on-premises data center is accessing to these VPCs. |
|
|
| A virtual gateway can only have one VPC associated. An on-premises data center |
| can access the same VPC over two connections through one virtual gateway. |
|
|
| Global DC Gateway |
|
|
| A global DC gateway enables your on-premises data center to access VPCs in |
| multiple regions so you can use a single connection to provide high-speed access |
| to cloud compute and storage resources in any region. |
|
|
| A global DC gateway can be attached to different enterprise routers to build a |
| central network so that your on-premises data center can access the VPCs in |
| different regions over the Huawei backbone network. This reduces network |
| latency, simplifies network topology, and improves O&M efficiency. |
|
|
| A global DC gateway can only be associated with connections terminated at the |
| same Direct Connect location. If there are multiple connections terminated at |

|
|
| different Direct Connect locations, you need to create multiple global DC |
| gateways. |
|
|
| Virtual Interface |
|
|
| A virtual interface is a point of entry for an on-premises data center to access a |
| VPC over a connection. A virtual interface associates a connection with a virtual |
| gateway and connects the virtual gateway to a remote gateway, enabling |
| communications between the on-premises data center and the VPC. |
|
|
| Virtual interfaces support static routing and BGP routing. You can use BGP to |
| connect your on-premises data center to the virtual gateway over a connection. |
| BGP helps you build a hybrid cloud more efficiently, flexibly, and reliably. |

| 11 Region and AZ |
|
|
| Concept |
|
|
| A region and availability zone (AZ) identify the location of a data center. You can |
| create resources in a specific region and AZ. |
|
|
| ● |
|
|
| ● |
|
|
| Regions are divided based on geographical location and network latency. |
| Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service |
| (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP |
| (EIP), and Image Management Service (IMS), are shared within the same |
| region. Regions are classified into universal regions and dedicated regions. A |
| universal region provides universal cloud services for common tenants. A |
| dedicated region provides specific services for specific tenants. |
|
|
| An AZ contains one or more physical data centers. Each AZ has independent |
| cooling, fire extinguishing, moisture-proof, and electricity facilities. Within an |
| AZ, computing, network, storage, and other resources are logically divided |
| into multiple clusters. |
|
|
| Figure 11-1 shows the relationship between regions and AZs. |
