What is an ECS

5

An Elastic Cloud Server (ECS) is a computing server consisting of the CPU, memory, and disks that allows real-time access, on-demand allocation and elastic scaling. In addition, it combines many services including the Virtual Private Cloud (VPC) and Cloud Server Backup Service (CSBS) to create an efficient, reliable, and secure computing environment. This ensures stable and uninterrupted operation of services. The resources, including CPUs and memory, used by an ECS are hardware resources that are consolidated using the virtualization technology.
When creating an ECS, you can configure its CPU, memory, mirroring specifications, login authentication mode and so on. After the ECS is created, you can use it on the cloud like using your local PC or physical server.

What Are ECS Protocols and Ports?

Backend ECSs provide network service protocols and ports. For example, if Internet Information Services (IIS) is installed on a Windows ECS, the default protocol is HTTP, and the default port is 80.


What are the application scenarios of an ECS
The ECSs allow users to quickly obtain virtual computing facilities that can scale up or down based on requirements. Through the network, companies around the world can use these elastic computing infrastructures. Users can rent computing and storage capabilities on demand at low costs, thereby greatly reducing hardware cost and encouraging them to focus on service ideas without worrying about servers, such as insufficient disk space. General-purpose scenario Applications: Web servers, development and testing environment, and small-scale database applications. Scenario characteristics: There is no special requirement on vCPU, memory, disk space or bandwidth, but there are high requirements on security and reliability. The scenarios feature low initial investment and maintenance costs. Application scenarios: Enterprise official website deployments, enterprise office automation (OA) setup, and enterprise development and testing activities.

What Can I Do with ECSs?

You can use ECSs just like traditional physical servers. On an ECS, you can deploy any service application, such as email systems, web systems, and Enterprise Resource Planning (ERP) systems.


What is requirement for eSpace ECS server hardware?
Requirement for ECS server hardware: RH2288 V3:2*E5-2620 CPU,2*16GB memory,4*600GB SAS hard disk,6*GE。 RH2285 V2:2*E5-2407 CPU,4*8GB memory,4*300GB or 8*300GB SAS hard disk,6*GE。 The typical configuration scenarios for less than 10000 UC users, the UM server uses a local hard drive, so you nee to configure 8*300GB or 4*600GB hard drive. In addition, supporting customer prepare server (HUAWEI, IBM, HP), server specification requirements greater than or equal to RH2285 V2 or RH2288.
