Overview
A Virtual Private Cloud (VPC) empowers you to construct a distinct network environment within the Cloud, offering tailored configurations for network segmentation, IP addressing, and routing protocols. It facilitates the establishment of VPN tunnels via public networks or Direct Connect, enabling seamless connectivity between your private network and diverse cloud resources, thus facilitating the agile deployment of hybrid cloud infrastructures.
Benefits
High Availability
Utilizing advanced technologies like network virtualization, redundant linkages, primary-secondary gateways, and VPC-based cross-availability zone deployment, the Cloud guarantees robust network availability while ensuring comprehensive protection of network security and reliability across linkages, networks, and IDC levels.
Complete Isolation
Using overlay technology, the Cloud enables the establishment of fully segregated private network environments, ensuring 100% logical isolation between various Virtual Private Clouds (VPCs), effectively addressing the security isolation requirements of your enterprise.
Diversified Access
Virtual Private Cloud (VPC) offers multiple networking options for establishing connectivity between your on-premises data center (IDC) and cloud assets, including Direct Connect and VPN connections.
High-performance Internet
Cloud technology facilitates ultra-high-performance Internet connectivity via NAT Gateway, accommodating up to 10 million simultaneous connections, effectively overcoming bottlenecks in Internet access. Moreover, NAT gateways seamlessly integrate with other Cloud services like Elastic Load Balancing and Anycast Internet Acceleration, enhancing the overall business access experience.
Multi-dimensional Security
VPC facilitates multi-faceted network security management, enabling precise control over resource access at both the port and instance levels via network ACLs and security groups. Additionally, it empowers users to implement granular account permissions through CAM, thereby ensuring elevated levels of network security.
Visual Management
VPC facilitates the professional visualization of network topology, enabling real-time monitoring of network status, configuration of traffic alerts, and comprehensive network management alongside Flow Logs for enhanced efficiency and intelligence.
Elastic Scalability
Cloud infrastructure enables VPC elastic scaling, obviating the necessity for procuring, deploying, and troubleshooting supplementary network hardware. This capability facilitates the agile adjustment of network resources in tandem with shifts in business scale, thereby bolstering organizational growth endeavors.
Optimal Costs
Many of the features within VPC come at no cost, affording users access to top-tier IDC-level network resources without the requirement of investing in extra specialized networking equipment. To achieve ideal setups, Cloud provides a range of adaptable billing options and packages.
Service Integration
VPC integration extends seamlessly across numerous Cloud services, including CVM, CDB, and TBDS, ensuring a holistic cloud solution for your needs.
Features
Software-defined Network
The IP address range, subnet IP address range, and routing strategies within VPC are customizable via the Cloud console or APIs. VPC can be subdivided into multiple subnets to facilitate the deployment of applications and services. Management of underlying network device deployment and operations, as well as the enhancement of network performance, are integral aspects of VPC optimization.
Internet Connection
VPC offers adaptable and high-capacity Internet connectivity, featuring Elastic IP (EIP) and NAT Gateway functionalities. EIP serves as a public IP address that can be independently obtained and utilized for online connectivity purposes. It supports the dynamic association and disassociation of instances (like CVM and NAT Gateway) to mitigate instance failures.
Hybrid Cloud Deployment
VPN Connection and Direct Connect facilitate the establishment of robust and dependable connections between cloud computing resources and on-premises IDCs, enabling the formation of a hybrid cloud environment. VPN Connection is a service that establishes an encrypted public IPsec tunnel between your IDC and VPC, enabling swift and secure deployment of a hybrid cloud infrastructure.
Interconnection with Cloud Resources
Interconnecting resources within VPC with other cloud resources is facilitated through Peering Connection (PC) and Classiclink. PC is a service designed to link two VPCs, supporting the exchange of traffic between VPCs across different accounts and regions. This allows resources like CVMs and CDBs to communicate bi-directionally. By utilizing PC, deploying unified global servers and implementing disaster recovery solutions spanning multiple regions and data centers becomes a straightforward endeavor.
Security Control
Achieve enhanced network security by leveraging network ACLs and security groups to control resource access at both the port and instance levels. By employing CAM to assign minimal account permissions, you can significantly bolster your network’s security posture. A stateless virtual firewall, Network ACL, filters specific packets and regulates inbound and outbound data traffic within a subnet based on protocol and port criteria.
