Elastic Compute Service

Overview

Benefits

Elastic Compute Service (ECS) supports custom server configurations, flexible and scalable business expansion, and high-performance network storage. This service helps you create a lightweight, secure, and efficient business environment.

Apply on demand

You can choose from a variety of computing specifications, such as General-purpose, Compute-optimized, Memory-optimized, Local-SSD, Big Data, and Elastic Bare Metal (EBM). Computing, storage, and network performance vary with specifications. You can apply for different ECS types and storage sizes based on your actual scenarios and start using them immediately.

Elastic and user-friendly

Elastic

ECS provides scalability for computing, storage, and networking, and flexible billing. This supports your rapid business expansion and changes.

Change of computing capacity: You can change the specifications of your ECS instances during peak periods or normal operations.

Volume expansion: As your data volume increases, ECS allows you to buy additional volumes or expand the capacity of existing ones based on your needs. You can expand storage online without the need to restart your server. This ensures continuous business operations.

Network architecture expansion: With services such as Direct Connect (DC) and Cloud Enterprise Network (CEN), you can establish connectivity between cloud and on-premises networks or between VPCs. This helps you expand your network and achieve interconnectivity across different networks.

Flexible billing: Different billing models are supported, including pay-as-you-go and subscription plans, and you can change the billing method. This allows you to change your resources based on your needs.

User-friendly

ECS provides multiple ways for you to manage cloud resources. This helps you perform O&M tasks.

ECS console: A web-based management interface provided by ECS. You can perform O&M actions on ECS instances and other resources on a user-friendly interface.

OpenAPI: ECS offers a set of industry-standard API endpoints. OpenAPI allows you to manage cloud resources and integrate ECS instances with internal systems to meet specific business requirements. This provides support for your business operations. You can use HTTP or HTTPS protocols for request communication to make online API calls or perform secondary development.

Security

ECS provides a range of security services to protect your cloud assets.

VPC: You can create a secure and customizable virtual network environment for your cloud resources to ensure business security.

Identity and Access Management: A robust permission management system is provided. It allows you to assign and manage user permissions based on your needs. This prevents unauthorized access and reduces security risks.

Monitoring: The status of various cloud resources is displayed. Cloud Monitor allows you to access performance metrics and operational status, and timely receive alarm notifications in case of failures. This ensures smooth business operations.

Deployment set: A deployment set allows you to manage the distribution of instances across underlying hardware and enable physical isolation. By creating deployment sets, you can distribute instances across different physical servers. This ensures underlying disaster recovery capabilities and high availability.

Cloud DDoS Protection_Basic: VolcanoEngine Cloud DDoS Protection_Basic is provided for resources like Classic Load Balancer (CLB) and Elastic Compute Service (ECS) on VolcanoEngine. This helps you meet security requirements in daily O&M. By default, basic DDoS protection capabilities are enabled for users on the cloud. This way, the system monitors attacks in real time and responds within seconds.

High performance

ECS provides high network throughput performance. The maximum throughput varies with the instance type. Instances of higher computing capacity provide enhanced network throughput capability.

ECS is configured with high-performance local SSDs and HDDs. This can meet the storage I/O requirements of demanding scenarios such as database storage and big data analysis.

Cost optimization

Three billing methods are provided to meet your needs in different application scenarios: Subscription, Pay-as-you-go, and spot instance.

You can also improve cost effectiveness by using the Reserved Instances (RI) discount method.

Comprehensive product ecosystem

ECS can be combined with advanced and highly available intelligent application suites, technology platforms, containers, and middleware services, etc. This way, ECS empowers your business at various dimensions and facilitates growth of the enterprise.

Intelligent O&M

Full-link automated O&M hosting policies are provided. The system can independently perform tasks such as detection, issue identification, and fault recovery. You can customize O&M policies based on your business needs.
