Cloud Virtual Machine (CVM) of Tencent Cloud provides secure and reliable elastic computing services and builds a basic computing power service that combines stability and flexibility by using software-defined computing, networking, and storage. Without the need to estimate resource usage or make initial investments, you can quickly obtain and use computing resources on the cloud and scale them in real time based on business needs, effectively reducing software and hardware purchase costs and IT Ops complexity.
Comprehensive Coverage: Global Resources and Support for Scenario-based Computing Power
CVM provides a full-stack computing service capability to meet diverse business scenario needs:
Global infrastructure: Tencent Cloud CVM resources are available in multiple regions across China, Asia-Pacific, Europe, and the Americas, enabling application deployment on the clients close to users' business locations and significantly reducing access latency.
Comprehensive scenario coverage: Tencent Cloud provides diverse options for various users, including instance families such as general computing, high I/O, big data, and heterogeneous computing, to meet different business scenario needs.
Industry-wide coverage: Tencent Cloud CVM provides comprehensive solutions across global industries through multi-region deployment, diverse computing power support, and deep industry adaptation.
Games/Pan-entertainment: Tencent Cloud CVM provides high-performance, low-latency global node deployments for major games such as Honor of Kings, League of Legends, and PUBG, supporting massive concurrent player loads.
Pan-financial service industry: The highly reliable architecture on the cloud meets the stability requirements of payment systems and trading databases. High I/O instances ensure low latency and data security for financial businesses.
Retail and consumption: CVM, combined with Cloud Object Storage (COS) and Cloud Load Balancer (CLB), supports high-concurrency order processing and large-traffic promotional campaigns.
Healthcare: Computing instances support high-performance computing scenarios such as gene analysis and drug discovery; big data instances handle medical imaging and clinical data.
Emerging Web3 field: GPU instances accelerate deep learning and blockchain computing; edge security platforms ensure global node protection.
Elasticity: Minute-Level Resource Adjustment
CVM achieves industry-leading elasticity, which supports dynamic scaling of businesses:
Hardware elasticity: Instances based on Cloud Block Storage (CBS) can instantly upgrade and downgrade CPU, memory, and disk configurations (regardless of the billing type).
Network elasticity: Support real-time bandwidth scaling and billing mode (bandwidth/traffic-based billing) switch.
System elasticity: Support a flexible switch between Windows/Linux operating systems in the Chinese mainland regions.
Architectural elasticity: Achieve network logical isolation through custom IP range segmentation, routing policies, and security group rules within Virtual Private Cloud (VPC).
Scalability coordination: Integrate with the Auto Scaling (AS) service to automatically scale instances based on load metrics, reducing idle costs by over 30%.
Reliable Assurance: Full-Linkage High Availability Architecture
CVM ensures business continuity through the multi-level disaster recovery design:
Instance reliability: Support the single-instance availability of 99.975%, data durability of 99.9999999%, and imperceptible migration upon downtime.
Storage reliability: CBS provides data reliability of 99.9999999% and supports snapshot backups.
Network architecture: Operate in T3+ data centers, using NIC binding and network virtualization technologies to ensure high availability of the network.
Fault tolerance and disaster recovery: The self-developed scheduling system VStation enables seamless business migration through cross-AZ deployment, stateless design, and minute-level disaster recovery failover mechanisms.
Ultra-Fast Experience: Breakthroughs in Both Performance and Efficiency
Deployment efficiency: Hundreds of compute instances can be created in batches within minutes. A single instance can be created in just 3 seconds, achieving a record of deploying 1 million core instances in 8 days.
Network quality:
Public network: 20-line BGP coverage across all major ISPs with second-level failover.
Private network: underlying 10 Gbps/1 Gbps networks, with low-latency communication between data centers in the same region.
Scheduling performance: The self-developed VStation system achieves elastic scale-out of 1,000 instances within 28 seconds, with the API processing capability achieving over 10,000 QPS.
Security Assurance: End-to-End Protection System
Tencent Cloud security team builds a five-dimensional integrated security protection system based on CVM:
Infrastructure security: Security groups and network access control lists (ACLs) implement port-level access control, and support logical isolation within VPC.
Data security: The recycle bin mechanism protects yearly/monthly subscription instances that are expired from accidental deletions, preventing data loss.
Security service: Free 24/7 protection is provided, including anti-DDoS, intrusion detection, vulnerability scanning, and website Trojan detection.
Ops security: Multiple access methods such as key-based login, password login, and VNC login are supported, with traceability of the operation process.
Fault prediction: Use the live migration technology to proactively avoid faulty nodes, resulting in an 80% reduction in fault rates perceived by customers.
Lower Costs: Flexibly Optimizing Investments
Tencent Cloud provides various billing methods to reduce traditional IT Ops costs, while optimizing the unit computing power costs continuously, therefore achieving leading comprehensive cost-effectiveness.
Hardware innovation: Self-developed high-density servers significantly reduce unit computing power costs by increasing the virtual machine deployment density of a single physical server, optimizing costs by over 45%.
Efficient combination: AMD EPYC processor + 200 Gbps network architecture. Only half the number of devices is required to handle the same business load as that of the original cluster, reducing Ops and energy consumption costs.
Flexible billing: Support pay-as-you-go (PAYG), saving plan, yearly/monthly subscription, and spot instances to meet different workload scenario needs.
Stable business: The 5-year long-term scheme further reduces costs by 30%, securing long-term returns.
Elastic business: The spot instance provides the lowest discounts, supporting scheduled automatic scaling.
Tencent Cloud CVM, as the core foundational service at the IaaS layer, has supported over 2 million subscribed customers, ranking first in scheduling scale within the industry. With comprehensive strengths including coverage, elasticity, reliability, ultra-fast experience, security, and low cost, CVM has become the preferred choice in terms of the general computing base for enterprises migrating to the cloud.
