Elastic Compute Service

Elastic Compute Service (ECS) is an elastic computing service based on host virtualization technology. It integrates servers, bandwidth and storage services, being highly reliable, manageable and flexible. ECS is classified into various specifications according to their performance and availability levels. You can choose the right configuration as per the business, which greatly reduces your IT procurement and operation & maintenance costs.

Value Proposition

Flexible and Easy to Use

It provides a variety of operating systems. Users can define the number of CPU cores, memory size, billing mode and service lifecycle to allocate resources reasonably and cut costs.

Rapid Deployment

One ECS instance can be delivered within 1-2 minutes; users can get more instances with the same configuration through cloning technology, thus saving deployment time.

Elastic Expansion

Upgrade and expand ECS instances at any time in line with business development changes to ensure rapid business growth. The CPU and memory can be upgraded within 5 minutes after a shutdown; the bandwidth can be upgraded online without a shutdown.

Secure and Reliable

Provide security protection functions like PHS and DDoS protection; with the instance availability rate being above 99.94%;

Use Cases

General Scenarios
Financial-grade Scenarios
Computing-intensive Scenarios

Business requirements
Common scenarios such as official websites of enterprises, small and medium-sized databases, and back-end server scenarios such as small and medium-sized systems require a certain amount of memory for data processing, cache clustering, and other enterprise applications. At the same, IT costs need minimizing.

Suggestions on cloud migration
For Web services, applications, and databases that do not have special demands on CPU, memory, and bandwidth, they only need to be deployed on a small number of servers. With the business grows in the future, you may extend the configuration of the server.

Functionality

Rapid Image Deployment

By creating a custom image, you can include all operating system and data environment information in the image, load the image when creating new instances and use the same image to start different types of instances, so as to greatly improve the deployment efficiency.

Replicate images across regions: You can quickly deploy the same cloud server instance in different regions to improve robustness of applications.

The image service does not require any additional fees other than the standard access fees for ECS instances and storage.

Financial-grade Security Monitoring

Performance monitoring: After the cloud host is created, the agent for performance data collection will be automatically installed during system initialization, which comes with monitoring function for free without requiring manual intervention. The resource utilization and running performance of ECS instances are monitored at the minute level (including more than 60 indicators like CPU utilization, disk read-and-write speed, and network traffic).

Trigger alerts and actions: Send you an alert notification or perform other automated actions by setting an alert policy. For example, when a monitoring indicator exceeds the threshold you set, you may use auto scaling to increase or decrease the number of instances.

Snapshot One-click Cloning

Full cloning of a disk at a point in time through automatic/manual snapshots, includes the entire data state of the disk at this time.

Day-to-day backup: Automatically create a snapshot of important data disks to complete day-today backups on a regular basis, such as daily, weekly, and monthly.

Application upgrade: Create a disk snapshot before upgrading the application software. Where an upgrade exception occurs, you can quickly roll back to the pre-upgrade disk state.

Significant changes: Create a snapshot before modifying system variables and global configurations, installing patches, or upgrading. Where an exception occurs, you can use the snapshot disk to roll back and restore the business quickly.

Flexible Reconfiguration

Configurations can be adjusted online within minutes. Users may upgrade or downgrade host configurations in line with their business needs. The CPU and memory can be upgraded within 5 minutes after a shutdown; the bandwidth can be upgraded online without a shutdown.
