Enterprise-level instances and entry-level instances FAQ

Last Updated: Jan 29, 2018

1. What are enterprise-level instances and entry-level instances?

In September 2016, Alibaba Cloud released enterprise-level instances. enterprise-level instances are a collection of instance type families that feature high performance, stable computational capabilities, and balanced network performance. Designed with exclusive and stable computing, storage, and network resources, enterprise-level instances are ideal for enterprise scenarios where high business stability is required.

Entry-level instances are ideal for small and mid-sized websites or individual customers. Compared with enterprise-level instances, entry-level instances highlight the sharing of resource performance. Their computing performance may be unstable, but the cost is relatively low.

2. Which are enterprise-level instances and entry-level instances?

Instances of all the instance type families listed in Instance type families, except for the following instance families, are enterprise-level instances:

  • Generation I: All the instance type families
  • Generation II: n4, mn4, xn4, and e4
  • Generation III: n1, n2, and e3

3. Which business scenarios are enterprise-level instances ideal for?

Enterprise-level instances are ideal for the following scenarios:

  • Massively Multiplayer Online Game (MMO) front ends, data analysis, and computing
  • Mid and large-sized Web servers featuring high concurrency
  • Computing scenarios with a fixed performance, such as high-precision coding/decoding, rendering, and gene computing by using a CPU
  • Other computing scenarios with a fixed performance, such as Cache/Redis, search, in-memory databases, databases with a high I/O (for example, Oracle and MongoDB), Hadoop clusters, and mass data processing

4. How is the network performance of enterprise-level instances?

The network performance of a enterprise-level instance is determined by its specification. Higher-level specification means higher network performance. For more information about the network performance of each instance type, see Instance type families.

5. Which disk categories are supported by enterprise-level instances?

Enterprise-level instances support Ultra Cloud Disks and SSD Cloud Disks.

6. Which image types are supported by enterprise-level instances?

Images of all operating systems are supported.

7. What are the limits on changing the configurations of enterprise-level instances?

The following rules apply when you change the configurations of enterprise-level instances:

  • You can change configurations between sn2, sn2ne, sn1, sn1ne, se1, and se1ne and within one of these families.
  • You can change configurations between c4, cm4, and ce4 and within one of these families.
  • You can change configuration between hfc5 and hfg5 and within one of these families.
  • You can change configurations only within the gn4 family.
  • You cannot change configurations of d1, d1ne, i1, i2, gn5, ga1, and f1 instances.

8. Can I upgrade entry-level instances to enterprise-level instances?

The following types of entry-level instances can be upgraded to enterprise-level instances:

  • You can change the type of an I/O-optimized VPC instance from c1, c2, m1, m2, s1, s2, s3, or t1, to sn1, sn2, or se1.
  • You can change the type of a VPC instance from types of Generation 2 or 3, including n1, n2, e3, n4, mn4, xn4, and e4, to sn1, sn2, or se1.
