The main difference between Alibaba Cloud t5 n4 g5 c5 and other series of servers

 

General instance type family g6 (g5 upgraded version)

The features of g6 are as follows:

• Relying on the Shenlong architecture, offloading a large number of virtualization functions to dedicated hardware, reducing virtualization overhead, and providing stable and predictable ultra-high performance
  I/O optimization examples

• Support ESSD cloud disk, SSD cloud disk and efficient cloud disk

  Note that the upper limit of cloud disk performance is different for different instance type families. A single g6 instance supports up to 200,000 IOPS.

• Instance storage I/O performance corresponds to computing specifications (the higher the specifications, the stronger the storage I/O performance)

  Note For the storage I/O performance table of the new generation of enterprise instance type families, see Storage I/O Performance.

• The ratio of processor to memory is 1:4
• Supports enabling or disabling the hyper-threading configuration
  > It means that the ECS instance enables the hyper-threading configuration by default. For more information, please refer to the custom CPU option.
• Ultra-high network PPS packet sending and receiving capability
  > It means that the upper limit of network performance is different for different instance type families. If you need higher network packet forwarding ability, it is recommended that you choose g5ne. For more information, please refer to network enhanced instance type family g5ne.

g6 configuration

• Processor: Intel ® Xeon ® Platinum 8269CY (Cascade Lake) with a main frequency of 2.5 GHz, a turbo frequency of 3.2 GHz, and stable computing performance
• The instance network performance corresponds to the computing specifications (the higher the specification, the stronger the network performance)
• Support change configuration to c6 or r6

Applicable scene:

• High network packet sending and receiving scenarios, such as video barrage, telecom service forwarding, etc.
• Enterprise-level applications of all types and sizes
• Website and application server
• Game server
• Small and medium database system, cache, search cluster
• Data analysis and calculation
• Computing clusters, memory-dependent data processing

Summary: Independent CPU, does not occupy CPU resources with others, and has extremely high network performance.

G5, general-purpose instance type family

The features of g5 are as follows:

• I/O optimization example
• Supports ESSD cloud disks, SSD cloud disks, and high-efficiency cloud disks
  > Explain that the upper limit of cloud disk performance is different for different instance type families, and a single g5 instance supports up to 200,000 IOPS.
• The ratio of processor to memory is 1:4
• Ultra-high network PPS receiving and sending capacity

g5 configuration is as follows

Processor: 2.5 GHz Intel ® Xeon ® Platinum 8163 (Skylake) or 8269CY (Cascade Lake), stable computing performance. The
instance network performance corresponds to the computing specifications (the higher the specifications, the stronger the network performance)

Applicable scene:

• High network packet sending and receiving scenarios, such as video barrage, telecom service forwarding, etc.
• Enterprise-level applications of all types and sizes
• Small and medium database system, cache, search cluster
• Data analysis and calculation
• Computing clusters, memory-dependent data processing

Computing instance type family c6 (can be considered as an upgraded version of c5)

The features of c6 are as follows:

• Relying on the Shenlong architecture, offloading a large number of virtualization functions to dedicated hardware, reducing virtualization overhead, and providing stable and predictable ultra-high performance
• I/O optimization example
• Support ESSD cloud disk, SSD cloud disk and efficient cloud disk
• Instance storage I/O performance corresponds to computing specifications (the higher the specifications, the stronger the storage I/O performance)
• Supports turning on or off hyper-threading configuration
• The ratio of processor to memory is 1:2
• Ultra-high network PPS receiving and sending capacity

Configuration

• Processor: Intel ® Xeon ® Platinum 8269CY (Cascade Lake) with a main frequency of 2.5 GHz, a turbo frequency of 3.2 GHz, and stable computing performance
• The instance network performance corresponds to the computing specifications (the higher the specification, the stronger the network performance)
• Support change configuration to g6 or r6

Applicable scene:

• High network packet sending and receiving scenarios, such as video barrage, telecom service forwarding, etc.
• Web front-end server
• Front end of massively multiplayer online game (MMO)
• Data analysis, batch calculation, video coding
• High-performance scientific and engineering applications

As for the t5 server, it is a relatively poor CPU (for example, a 15% baseline, then when the CPU usage exceeds 15%, it will consume points, and will always be below 15% after consumption. Of course, idle (that is, no more than 15%) Time will be able to accumulate points) limit, suitable for general personal blog system.

The main difference between the above models: c6&c5/g6&g5: Exclusive products use fixed CPU scheduling mode. Each vCPU is bound to a physical CPU hyperthread. There is no CPU resource contention between instances. The instance computing performance is stable and has strict SLA guarantees, which is suitable for enterprise-level applications and scenarios of various scales.
n4/mn4: Shared products use unbound CPU scheduling mode. Each vCPU will be randomly assigned to any idle CPU hyperthread, but the cost performance is higher.

So for the average person, you can choose a cheap version for applications such as blogs, small programs , APPs, and micro web pages. If you need extremely high performance, you need to pay attention to g-series or c-series hosts.
