　　 What is the Aliyun of the example specification family?

According to the configuration of the ECS instance specification of cloud server and the different application scenarios, the example specification is divided into several example specification families.

Instance Series I

Example series I of all specifications are the old sample specifications, still in accordance with the previous 1 cores, 2 cores, 4 cores, 8 cores, 16 cores of the way to divide the selection of groups, not sensitive to the specification family.

Instance Series II

The example series II contains the specification family in the table below.

Specification Family	description	features	use scene
Universal N1	The newest generation of generic ECS instance types, with a new generation of CPUs and memory, more computational power, faster I/O capability. &NBSP The small specification instance type in N1 is suitable for entry-level users, and large size instance types are suitable for use in specific fields such as games, rendering, genetics, coding, and depth learning.	Intel Xeon e5-2680 V3 (Haswell) processor 2.5GHZ Frequency I/O optimization instance	small Web application, small to medium number Database Large multiplayer online gaming (MMO) front-end, data analysis and computing; Medium Large Web server (high concurrency) use CPU for high-precision codec, rendering, Gene computing
Universal N2	The newest-generation universal EC S instance type, with a new generation of CPUs and memory, with more computational power and faster I/O capability. The is larger in size than the N1,N2 specification family, and has a wider range of options.	Intel Xeon e5-2680 V3 (Haswell) processor 2.5GHZ Frequency larger memory selection range I/O optimization instance	small Web applications, small and medium sized databases; Large Multiplayer online gaming (MMO) front-end, data analysis and computing; Medium Large Web server (high concurrency); use CPU for high-precision codec, rendering, gene calculation; Hadoop Cluster, a large number of data processing.
memory-type E3	The latest generation of memory-intensive ECS instance types, with a new generation of CPUs and memory, more powerful computing power, and a larger range of memory options. The is suitable for computing services that require large amounts of memory-operation lookups, and applications that require a large number of I/O operations.	Intel Xeon e5-2680 V3 (Haswell) processor 2.5GHZ Frequency Memory-intensive I/O optimization instance	do Cache/redis, search for classes, memory databases, etc. that require a large amount of memory to be used; High I/O databases, such as Oracle,mongodb; Hadoop Cluster, a large number of data processing.
