The Virtual Private Cloud (VPC) helps you build independent network space in Tencent Cloud and allows you to customize network segment classification, IP addresses, and routing policies. You can establish VPN tunnels through the public network/direct connection to connect the private network to other cloud resources, thereby flexibly deploying hybrid clouds.
Leveraging sophisticated technologies such as network virtualization, linkage redundancy, master/slave gateway and VPC-based cross-availability zone deployment, Tencent Cloud ensures high network availability and comprehensively protects network security and reliability at the linkage, network and IDC levels.
Utilizing overlay technology, Tencent Cloud helps you build a completely isolated private network environment with 100% logical isolation of different VPCs, meeting the security isolation needs of your businesses.
VPC provides you with various ways of network access to connect your local IDC to Tencent Cloud resources, such as Direct Connect and VPN Connections.
Tencent Cloud enables ultra high-performance Internet access through NAT Gateway which supports up to 10 million concurrent connections, helping you easily break through bottlenecks with Internet access performance. Additionally, NAT gateways can be used alongside other Tencent Cloud products such as elastic Load Balance and Anycast Internet Acceleration for an improved business access experience.
VPC supports multi-dimensional network security control. Resource access control at the port and instance levels can be achieved through network ACLs and security groups, and minimum account permissions can be granted through CAM, helping you achieve comprehensive network security enhancement.
VPC supports visualization of network topology which can monitor network status in real time, set traffic alarms and help you easily manage networks in a comprehensive and intelligent manner together with Flow Logs.
Tencent Cloud supports elastic scaling of VPC, eliminating the need to purchase, install and debug additional network devices, allowing for flexible scaling of network resources as business scale changes and helping with business development.
Most functions of VPC are available free of charge, allowing you to enjoy high-standard IDC-grade network resources without the need to purchase additional dedicated network devices. For optimal configurations, Tencent Cloud offers a variety of flexible billing methods and packages.
VPC can be deeply integrated with most Tencent Cloud services such as CVM, CDB and TBDS to provide you with a complete cloud solution.
The IP address range, subnet IP address range and routing strategies of VPC can be customized through the Tencent Cloud console or API. VPC can be further divided into multiple subnets for deployment of applications and services. The deployment and OPS of underlying network devices and optimization of network performance are maintained by Tencent Cloud's professional technical team, allowing you to focus on defining instantly available networks with software to build transparent, agile and intelligent networks with ease.
VPC provides you with flexible and high-performance Internet connectivity, including elastic IP (EIP) and NAT gateway.
EIP is a public IP address that can be independently applied for and used for Internet access. It supports dynamic binding and unbinding of instances (such as CVM and NAT gateway) for blocking instance faults.
NAT gateway (NG) is a method for VPC to access the Internet. It can translate the private IP address in VPC to a public IP address if the private and public networks are isolated from each other. A typical application scenario of NG is to achieve high-bandwidth and high-availability Internet access. NG supports up to 10 million concurrent connections, 10 Gbps bandwidth and 10 EIPs and features dual-server hot backup, automatic disaster recovery and 99.99% service availability, making it ideal for Internet access scenarios requiring high bandwidth and with large volumes of public IP addresses and multiple deployed services.
VPN Connections and Direct Connect can be used to establish stable and reliable connections between Tencent Cloud computing resources and local IDCs so as to create a hybrid cloud.
VPN Connections is a service that connects your IDC to VPC through an encrypted public IPsec tunnel, helping you to deploy a hybrid cloud quickly and securely.
Direct Connect is a service that connects your IDC to Tencent Cloud computing resources through physical direct connect lines and supports dual-server hot backup, satisfying the need for high-quality network connections in industries such as finance.
You can interconnect resources in VPC with other cloud resources through Peering Connection (PC) and Classiclink.
PC is a service that connects two VPCs and supports traffic interconnection of cross-account and cross-region VPCs, enabling resources such as CVMs and CDBs to access each other at both ends. With the aid of PC, you can easily deploy unified global servers and 2-region-3-DC disaster recovery schemes.
Classiclink is a service that is used to associate CVMs on a basic network to a specified VPC and enables network communication between the CVMs and the VPC, helping you seamlessly connect to Tencent Cloud resources.
Resource access control at the port and instance levels can be achieved through network ACLs and security groups, and minimum account permissions can be granted through CAM, helping achieve comprehensive network security enhancement.
Network ACL is a stateless virtual firewall that can filter selected packets and control the inbound and outbound data traffic on a subnet at the protocol and port levels.
Security group is a stateful packet-filtering virtual firewall that controls the inbound and outbound traffic of one or multiple CVMs at the protocol and port levels.
High-traffic Video and Live Broadcasting Business
A cloud-based interactive live broadcasting platform can be easily built, which supports real-time transmission of over 100 GB of video, satisfies live broadcasting needs of one-to-many elastic transcoding on private networks and ensures a smooth user experience in different scenarios.
● With the help of VPC, a high-performance 10 Gbps cloud network can be built which supports one-to-many transcoding.
● High-bandwidth elastic IP supports transmission of over 3 GB of video.
● Bandwidth sharing among multiple IPs can be achieved based on Bandwidth Package to reduce costs.
The IoT service architecture built in Tencent Cloud makes it easy to process billions of connection requests generated by numerous devices in the sharing economy such as shared power banks, shared bicycles and unmanned stores.
● CLB supports high volumes of concurrent requests to meet massive IoT demands.
● Over 35 BGP lines fulfills access by IoT devices in any region.
● NG protects private network resources when accessing the Internet.
Online games typically have players all over the world and servers deployed in multiple regions. PC makes it easy for games to cope with network latency-sensitive scenarios such as cross-server PvP battles to improve the player experience.
● PC can build stable networks with low latency, meeting the cross-server gaming needs of global players.
● Tencent Cloud boasts 45 availability zones across 25 geographical regions around the world, allowing for proximity-based business deployment that satisfies the access needs of players in different regions.
2-region-3-DC Cloud-based Disaster Recovery
