Enterprise-level instance FAQ
What is an enterprise-level instance? What is an entry-level instance?
Enterprise-class instances are the general name for a series of instance specification families launched by Alibaba Cloud in September 2016. They feature high performance, stable computing capabilities, and balanced network performance. Because they have exclusive and stable computing, storage, and network resources, these instance specification families are very suitable for enterprise scenarios that have high requirements for business stability.
Entry-level instances are a general term for a series of instance specifications (families) targeted at general small and medium-sized websites or individuals. Compared with enterprise-level instances, entry-level instances place more emphasis on sharing resource performance in terms of resource utilization, so they cannot guarantee the stability of instance computing performance, but the cost is relatively lower.
What is the essential difference between enterprise-level instances and entry-level instances?
Enterprise-level instances adopt fixed CPU scheduling mode. Each vCPU is bound to a physical CPU hyperthread, and there is no competition for CPU resources between instances. Instance computing performance is stable and has strict SLA guarantees.
Entry-level instances adopt non-bound CPU scheduling mode. Each vCPU will be randomly assigned to any idle CPU hyperthread. Different instance vCPUs will compete for physical CPU resources, causing unstable computing performance fluctuations under high load. There is an availability SLA guarantee, but no performance SLA guarantee.
What are enterprise-level instances? What are the entry-level instances?
Currently, among the instance specification families on sale, entry-level instances include: n4, mn4, xn4, and e4. Other instance specification families on sale are enterprise-level instances.
Under what business scenarios do I need to purchase enterprise-level instances?
Enterprise-level instances are suitable for the following scenarios:
Massively multiplayer online game (MMO) front-end, data analysis and calculation
Medium and large web servers (high concurrency )
Use the CPU for fixed performance computing scenarios such as high-precision encoding and decoding, rendering, and genetic computing
Cache/Redis, search classes, memory databases, and high I/O databases such as Oracle and MongoDB , Hadoop cluster, large amounts of data processing and fixed performance computing scenarios
What is the network performance of enterprise-level instances?
The network performance of enterprise-level instances is related to the instance specifications: small-sized instances have low network performance, while large-sized instances have high network performance. For network performance corresponding to different instance types, see Instance Type Family.
What cloud disk types are supported by enterprise-level instances?
Enterprise-level instances support high-efficiency cloud disks and SSD cloud disks.
What types of images are supported by enterprise-level instances?
Supports images of all operating systems.
What are the restrictions on changing enterprise-level instance specifications?
Configuration rules for enterprise-level instances:
sn2ne, sn1ne, se1 and se1ne can be reconfigured with each other and within the specification family.
The ce4 specification family can be configured with each other.
hfc5 and hfg5 can be matched with each other as well as within the specification family.
gn4 can only be changed within the specification family.
d1, d1ne, i1, i2, gn5, ga1, and f1 do not support configuration changes.
Can entry-level instances be converted into enterprise-level instances?
Series III VPC network type ECS instances (including n4, mn4, xn4, and e4) can be configured to se1.

Linux: A Deep Dive into Its Fundamental PartsApr 21, 2025 am 12:03 AMThe core components of Linux include kernel, file system, shell, user and kernel space, device drivers, and performance optimization and best practices. 1) The kernel is the core of the system, managing hardware, memory and processes. 2) The file system organizes data and supports multiple types such as ext4, Btrfs and XFS. 3) Shell is the command center for users to interact with the system and supports scripting. 4) Separate user space from kernel space to ensure system stability. 5) The device driver connects the hardware to the operating system. 6) Performance optimization includes tuning system configuration and following best practices.
Linux Architecture: Unveiling the 5 Basic ComponentsApr 20, 2025 am 12:04 AMThe five basic components of the Linux system are: 1. Kernel, 2. System library, 3. System utilities, 4. Graphical user interface, 5. Applications. The kernel manages hardware resources, the system library provides precompiled functions, system utilities are used for system management, the GUI provides visual interaction, and applications use these components to implement functions.
Linux Operations: Utilizing the Maintenance ModeApr 19, 2025 am 12:08 AMLinux maintenance mode can be entered through the GRUB menu. The specific steps are: 1) Select the kernel in the GRUB menu and press 'e' to edit, 2) Add 'single' or '1' at the end of the 'linux' line, 3) Press Ctrl X to start. Maintenance mode provides a secure environment for tasks such as system repair, password reset and system upgrade.
Linux: How to Enter Recovery Mode (and Maintenance)Apr 18, 2025 am 12:05 AMThe steps to enter Linux recovery mode are: 1. Restart the system and press the specific key to enter the GRUB menu; 2. Select the option with (recoverymode); 3. Select the operation in the recovery mode menu, such as fsck or root. Recovery mode allows you to start the system in single-user mode, perform file system checks and repairs, edit configuration files, and other operations to help solve system problems.
Linux's Essential Components: Explained for BeginnersApr 17, 2025 am 12:08 AMThe core components of Linux include the kernel, file system, shell and common tools. 1. The kernel manages hardware resources and provides basic services. 2. The file system organizes and stores data. 3. Shell is the interface for users to interact with the system. 4. Common tools help complete daily tasks.
Linux: A Look at Its Fundamental StructureApr 16, 2025 am 12:01 AMThe basic structure of Linux includes the kernel, file system, and shell. 1) Kernel management hardware resources and use uname-r to view the version. 2) The EXT4 file system supports large files and logs and is created using mkfs.ext4. 3) Shell provides command line interaction such as Bash, and lists files using ls-l.
Linux Operations: System Administration and MaintenanceApr 15, 2025 am 12:10 AMThe key steps in Linux system management and maintenance include: 1) Master the basic knowledge, such as file system structure and user management; 2) Carry out system monitoring and resource management, use top, htop and other tools; 3) Use system logs to troubleshoot, use journalctl and other tools; 4) Write automated scripts and task scheduling, use cron tools; 5) implement security management and protection, configure firewalls through iptables; 6) Carry out performance optimization and best practices, adjust kernel parameters and develop good habits.
