Variety of Models and Specs
There are four CDH options currently being offered: standard, MEM optimized, computing and high-I/O.
• Standard: Features balanced computing, memory and network resources that can meet application resource requirements in most scenarios.
• MEM optimized: Features large memory, suitable for applications requiring a large number of memory operations, lookups and calculations such as high-performance databases and distributed memory caches.
• Computing: Features high random IOPS, high throughput and low access latency, suitable for I/O-intensive applications such as high-performance databases with high disk read/write and latency requirements.
• High-I/O: Features the highest single-core computing performance, suitable for compute-intensive applications such as batch processing, high-performance computing and large-scale gaming servers.
Flexible Creation and Specs Adjustment
CVM instances can be created by specifying one or more CDHs. There are no limitations on CVM instance specs which can be customized based on the host resources, enabling you to plan and allocate resources independently and efficiently. A wide range of computing, network and disk options and adjustments are available. You can up-grade/downgrade the CPU and memory specs of the CVM instance and upgrade the disk specs.
Multiple Regions and Availability Zones
Tencent Cloud boasts hosted IDCs in many regions around the globe, so you can choose a region close to your target clients for CDH deployment, significantly reducing access latency and enhancing user experience.
There are multiple availability zones in each region. If your business requires high disas-ter recovery performance, CDH instances can be deployed in different availability zones in the same region to protect applications from being affected by the failure of a single availability zone.
