Elastic Cloud server (Elastic Cloud Server) is a self-help get ready, scalable computing power can be elastic cloud server,
3, computing services: GPU accelerated cloud server
4, computing services: elastically stretchable Services (AS)
elastically stretchable Service (Auto Scaling) according to business needs and policy for the user, automatically adjust computing resources, making the number of cloud servers as your business negative
load growth increases with traffic load lowering reduction, to ensure stable and healthy business.
5, storage services: cloud hard drive (EVS)
cloud hard disk (Elastic Volume Service) is based on a distributed architecture, elastically scalable virtual block storage service. With high data reliability, high I / O throughput capacity and other characteristics. The same as using a traditional server hard disk, you can mount the hard drive to the cloud to do on the cloud server format, create an operating system file, and persistent data storage.
6, storage services: Cloud backup hard disk (VBS)
cloud hard disk backup service (Volume Backup Service) cloud can create a backup hard drive, using the rollback cloud data backup hard drive to ensure maximum accuracy and security of user data, ensure data security .
7、存储服务：对象存储服务（OBS）
对象存储服务（OBS，Object Storage Service）是一个基于对象的海量存储服务，为您提供海量、低成本、高可靠、安全的数据存储能力。使用于：海量存储资源池、静态网站托管、大数据存储、备份、归档和网盘类业务。
高可用：11个9数据持久性和99.99%的可用性
低成本：成本低廉，海量扩展
易使用：提供S3原生接口以及基于web控制台，OBS客户端和SDK开发包等多种使用方式
8、网络服务：虚拟私有云（VPC）
虚拟私有云（Virtual Private Cloud）可帮助您基于华为云轻松构建隔离的虚拟网络环境。您可以完全掌控自己的虚拟网络，包括申请弹性带宽/IP、创建子网、配置DHCP、设置安全组等。此外您也可以通过专线/×××等连接方式将VPC与传统数据中心互联互通，灵活整合资源。
9、网络服务：弹性负载均衡（ELB）
弹性负载均衡（Elastic Load Balancing ）将访问流量自动分发到多台云服务器，扩展应用系统对外的服务能力，实现更高水平的应用程序容错性能。
10、安全服务：Anti-DDoS流量清洗
Anti-DDoS安全服务是通过专业的防DDoS设备来为客户互联网应用提供精细化的抵御DDoS***能力（包括CC、SYN flood、UDP flood等所有DDoS***方式）。租户根据租用带宽及业务模型自助配置防护阈值参数，系统检测到***后实时通知用户网站防御状态。
11、安全服务：漏洞扫描服务（VSS）
租户使用华为云安全控制台，通过对网站/主机的扫描，可以检测出网站/主机存在的漏洞，给出漏洞详情，针对每一种类型的漏洞给出专业的修复建议。
关键特性：
体验式扫描：支持第一次使用漏洞扫描服务的新用户，在未进行域名认证时，对网
站进行体验式扫描，预估网站风险
支持多种主机漏洞扫描
覆盖OWASP Top 10 漏洞检测
第三方开源软件的漏洞检测以及未知漏洞0day的检测。
覆盖多种Web指纹及主机指纹。
修复建议：针对检测发现的每种漏洞类型，提供了专业的修复建议。
12、安全服务：Web应用防火墙（WAF）
Web应用防火墙会对HTTP的请求进行异常检测，有效防止网页篡改、信息泄露、***植入等恶意网络***行为。
关键特性：
业界支持OS类型最广的防病毒产品， 支持多种不同的windows/linux系统。
突破传统防病毒产品的局限性， 提供深度的安全防护，为租户提供全方位的安全保护，包括:防******：包括SQL注入、XSS跨站、服务器漏洞、信息泄露、权限提升、命令执行、webshell、第三方漏洞、恶意扫描等。
隐藏云主机的弹性IP，替身式服务，保护云主机安全。
对网站的静态资源提供缓存，请求无需回源，即可在Web应用防火墙节点获取资源，加快网站访问速度。
13, cloud management: a unified identity authentication (IAM)
Unified Authentication Service (Identity and Access Management, referred to as IAM) is a Web service, customers can use the cloud Huawei Huawei cloud services to manage users and user rights. By using IAM, you can centrally manage user security credentials (such as access key) as well as permissions to control which users can access Huawei's cloud resources.
Key Features
centralized control and user security credentials: You can create control each user's Huawei cloud security credentials (such as access key), the rotation and revocation.
centralized control of user access: You can control data access and Huawei cloud system user can access.
permission-based user group: You can restrict the user's job responsibilities based on the user (such as administrators, developers, etc.) Huawei cloud access.
When the user enters the organization, you can easily update Huawei cloud user's access rights, to reflect changes in user roles.
Huawei customer service support and peacekeeping operations: You can let the Huawei customer service functions on behalf of enterprises registered by registered on behalf of, but also allows Huawei customer service work completed on behalf of Victoria function by switching roles.
14, cloud management: Cloud Monitoring Service (CES)
Cloud Monitoring Service (Cloud Eye Service) is a three-dimensional monitoring platform for elastic cloud server and bandwidth resources. Provide real-time monitoring alerts you notifications, and personalized report views, helping you understand precisely the product resource status.
15, software development cloud: a one-stop DevOps cloud platform
software development cloud (DevCloud) is a Huawei R & D practices, cutting-edge research and development concepts, advanced development tools for the integration of R & D cloud platform; development tools for developers to provide services to software development simple and efficient.
