Advantages

Advantages

Compared with traditional servers, ECSs are easy to provision and use, and have high reliability, security, and scalability.

Table 18-3 Comparison of ECSs with traditional servers

Item

ECS

Traditional Server

Reliability

The ECS service can work with other cloud services, such as storage services and disaster recovery & backup, to allow flavor modification, data backup, recovery using a backup, and rapid recovery from a fault.

  • Traditional servers, subject to hardware reliability issues, have a higher likelihood of failure. You need to manually back up their data.
  • You need to manually restore their data, which may be complex and time-consuming.

Security

The security service ensures that ECSs work in a secure environment. This service protects your data, hosts, and web pages, monitors program execution, and checks whether ECSs are under brute force attacks and whether remote logins are performed. This aims to enhance your system security and mitigate the risks of ECS intrusion by hackers.

NOTE:

The security service is supported only in Region Type I and II scenarios.

  • You need to purchase and deploy security measures additionally.
  • It is difficult to perform access control on multiple users to multiple servers.

Scalability

  • You can modify an ECS flavor, including the number of CPUs and memory size.
  • You can expand the capacity of the system disk and data disk.
  • Auto Scaling (AS) is used, which enables you to configure AS policies so that ECSs are automatically added and removed during traffic peaks and lulls, respectively. This ensures that your service requirements are met and maximizes resource utilization. This function is supported only in Region Type I and II scenarios.
  • Configurations are fixed and are difficult to meet changing needs.
  • Hardware upgrade is required for modifying configuration, which takes a long time and the service interruption time is uncontrollable. Service scalability and continuity are low.

Easy to use

  • A simple and easy-to-use unified management console streamlines operations and maintenance.
  • A wide range of products are provided, including network, storage, security, and big data devices, which can be provisioned and deployed at the one-stop manner. Security and big data are supported only in Region Type I and II scenarios.
  • Without software support, users must repeat all steps when adding each new server.
  • It is difficult for you to obtain all required services from one service provider.

Easy to provision

After deploying an entire private cloud and finishing necessary configurations, you can customize the number of CPUs, memory size, images, and networks to create ECSs at any time.

When using traditional servers, you must buy and assemble the components and install the operating systems (OSs).
