Huawei Cloud ECS
Huawei Cloud ECS
An Elastic Cloud Server (ECS) is a basic computing unit that consists of vCPUs, memory, OS, and Elastic Volume Service (EVS) disks.
After creating an ECS, you can use it like using your local computer or physical server, ensuring secure, reliable, and efficient computing.
The ECS lifecycle refers to the entire journey an ECS goes through, from creation to deletion (or release).
ECSs are more cost-effective than physical servers. Within minutes, you can obtain ECS resources from the cloud service platform. ECS resources are flexible and on-demand. This section describes how to purchase an ECS on the management console.
Logging In to a Windows ECS | Logging In to a Linux ECS | Follow-up Procedure
If you have added a data disk during ECS creation, you must initialize the data disk after logging in to the ECS.
Windows Server 2008 R2 Enterprise 64bit is used as an example to describe how to automatically initialize data disks attached to a server running Windows.
CentOS 7.4 64bit is used as an example to describe how to initialize data disks attached to a server running Linux using the initialization script.
An Elastic Cloud Server (ECS) is a cloud server consisting of vCPUs, memory, image, and Elastic Volume Service (EVS) disks that allow on-demand allocation and elastic scaling.

Huawei Cloud ECS Advantages
ECS supports automated scaling of compute resources based on traffic changes and predefined scaling policies. You can customize ECS specifications including vCPUs, memory, and bandwidth to let your applications run in a flexible, efficient environment.
Reliability
Differentiated EVS disks
Common I/O, high I/O, general purpose SSD, ultra-high I/O, and extreme SSD disks are available for all of your service requirements. You can store data on different types of disks for different needs.
Common I/O EVS disks: They are secure, reliable, and scalable. If your applications process few transactions and require large capacity and moderate read/write speed, you can store data on common I/O EVS disks.
High I/O EVS disks: They provide high performance, scalability, and reliability. If your applications require high performance, high read/write speed, and instant data storage, you can store data on high I/O EVS disks.
General purpose SSDs: This type of disks are cost-effective. You can use them for high-throughput, low-latency applications.
Ultra-high I/O EVS disks: They provide high performance and low latency. They are ideal for read/write-intensive applications requiring extremely high performance and low latency.
Extreme SSDs: They use RDMA that controls congestion at low latency. You can They are ideal for applications that require ultra-large bandwidth and ultra-low latency.
Distributed architecture
ECS provides scalable, reliable, and high-throughput virtual block storage on a distributed architecture. This ensures that data can be rapidly migrated and restored if any data replica is unavailable, preventing data loss caused by a single hardware fault.
Backup and restoration
You can set automatic backup policies to back up in-service ECSs and EVS disks. You can also configure policies on the management console or use an API to back up the data of ECSs and EVS disks at a specified time.
Security
Multi-dimensional protection
A number of security services, such as Web Application Firewall (WAF) and Vulnerability Scan Service (VSS) are available.
Security evaluation
Cloud security evaluation and security configuration check help you identify security vulnerabilities and threats, reducing or eliminating your loss from viruses or attacks.
Intelligent process management
You can customize an allowlist to automatically prohibit the execution of unauthorized programs.
Vulnerability scan
Comprehensive scan services are available, including general web vulnerability scan, third-party application vulnerability scan, port detection, and fingerprint identification.
Hardware and Software
Professional hardware devices
You can deploy ECSs on professional hardware devices that allow in-depth virtualization optimization, delivering best-in-class virtual server performance.
Virtualized resources accessible anytime, anywhere
You can obtain scalable, dedicated resources from the virtualized resource pool anytime, anywhere, so your applications can run in reliable, secure, flexible, and efficient environments. You can use your ECS like the way you are using your local computer.
Scalability
Automated scaling of computing resources
Dynamic scaling: AS automatically increases or decreases the number of ECSs in an AS group based on monitored data.
Periodic/Scheduled scaling: AS increases or decreases the number of ECSs in an AS group at a regular interval or a specified time based on the predicted load or a pre-set plan.
Flexible adjustment of ECS specifications
ECS specifications and bandwidth can be flexibly adjusted based on service requirements.
Flexible billing options
You have the flexibility to choose different billing options like yearly/monthly and pay-per-use based on your service characteristics.

ECS FAQs
Huawei FAQs
-
What Are the Precautions for Using ECSs?
Do not upgrade ECS kernel or OS versions. If you want to upgrade the main OS version, for example, from CentOS 7.2 to Cent OS 7.3, use the provided OS changing function.
Do not uninstall the performance optimization software pre-installed on your ECSs.
Do not change NIC MAC addresses. Otherwise, the network connection will fail.
-
How Do I Use BYOL?
What Is BYOL?
Bring your own license (BYOL) allows you to use your existing OS license, so you do not need to apply for a license again or pay for a license when you purchase an ECS.
How Do I Use BYOL?
If you select the BYOL license type, you can use your own OS license and manage it. The cloud platform allows you to maintain license compliance during the license lifecycle.
NOTE: BYOL is supported only if you create Windows ECSs on DeHs. -
Is Application Disaster Recovery Available in Different Regions?
Yes.
You can deploy active and standby application nodes in different regions. If the active application node is faulty, the standby application node continues to provide services.
-
What Is the Impact on Services When Resources Are Frozen, Unfrozen, or Released?
When resources are frozen, resource access and usage are restricted, which will interrupt your services. For example, if a server is frozen, it will be automatically stopped.
When resources are unfrozen, restrictions on resources are removed, but you need to check and restore your services. For example, after a yearly/monthly ECS is unfrozen, it will be automatically started. After a pay-per-use ECS is unfrozen, you need to start it manually.
When resources are released, data stored on the resources will be deleted and cannot be retrieved.
-
How Do I Configure CBR and HSS for My ECS?
CBR and HSS are not configured for an ECS by default, you can choose to use them based on service requirements.
You can view the backup policy on the CBR console and associate the policy with your ECS. HSS takes effect only after the agent is installed on an ECS.

-
Can a Deleted ECS Be Provisioned Again?
No. ECSs in the Deleted state cannot provide services and are soon removed from the system.
A deleted ECS is retained in the ECS list on the management console only for a short period of time before it is permanently removed from the system. You can purchase a new ECS with the same specifications again.
-
Can I Change the OS of an ECS?
Yes, you can change the OS of an ECS.
If the OS running on an ECS cannot meet service requirements, for example, a higher OS version is required, you can change the ECS OS.
The cloud platform allows you to change the image type (public images, private images, shared images, and Marketplace images) and OS. You can change the OS by changing the ECS image.
For instructions about how to change an ECS OS, see Changing the OS.
