Study Notes
Virtual Private Cloud (VPC)
- Provides a dedicated network for building and managing resources
- Allows configuration of subnets, security groups, and external network communication
- Offers a secure and isolated environment for deploying and managing resources
- Provides connectivity to the external network through Elastic IP (EIP) with configurable bandwidth
- Enables communication between resources within the VPC using private IP addresses
- Offers features like security groups, EIPs, and Elastic Load Balancer (ELB) for security, accessibility, and load balancing
Image Management Service (IMS)
- Facilitates creation and management of virtual machine images
- Allows creation of images for Elastic Compute Service (ECS) instances
- Supports using private images, providing rapid service deployment
Elastic Volume Service (EVS)
- Provides storage for ECS and Bare Metal Server (BMS) instances
- Offers scalable and reliable block storage for data persistence
Volume Backup Service (VBS)
- Offers data backup and recovery functions for EVS volumes
- Enables data protection and recovery in case of failures
Cloud Eye
- A monitoring service that tracks performance, reliability, and availability of ECS and BMS instances
- Offers real-time monitoring of resource usage including CPU, memory, and network
- Provides visibility into resource utilization and potential performance issues
Cloud Backup and Recovery (CBR)
- Supports data backup and recovery for EVS disks and ECS instances
- Creates snapshots for data recovery in case of accidental deletion or failure
E-commerce
- Features memory-optimized ECS for applications involving large amounts of data
- Highlights the challenges in e-commerce including sudden traffic surges, poor user experience, lack of analytics, and security vulnerabilities
- Emphasizes the need for scalable infrastructure, optimized data storage, comprehensive analytics, and robust security measures
Graphics Rendering
- Emphasizes the need for high-performance computing particularly GPUs to enable real-time rendering and highly concurrent operations
- Leverages the benefits of BMS for graphics rendering workloads, enabling dedicated hardware, robust performance, and high availability
- Recommends using GPU-accelerated ECS instances for real-time, massively parallel computations, and data-intensive processing
Core Database
- Highlights the benefits of BMS for core databases, including high security, performance, and reliability
- Emphasizes the use of BMS for critical workloads, demanding high performance and data integrity
- Emphasizes the use of BMS for applications that require isolation, high availability, and robust backup mechanisms
High-Performance Computing (HPC)
- Emphasizes the use of specialized HPC resources, including compute-intensive ECS instances and high-performance BMS instances
- Highlights the importance of networks with high bandwidth and low latency for HPC workloads
- Recommends a combination of high-performance ECS instances and BMS for optimal computing performance, resource isolation, and scalability
Bare Metal Server (BMS)
- Offers dedicated physical servers, eliminating virtualization overhead for maximum performance
- Provides high security as each BMS is dedicated to a single tenant
- Features three-copy backup for enhanced data security and reliability
- Offers quick provisioning with automatic OS installation and network configuration
- Supports Real Application Clusters (RAC) for enterprise-scale deployments

- Provides secure communication with other cloud resources using VPC and accessibility through EIPs
Comparison Between BMS, ECS, and Physical Server
- High performance is a significant advantage of physical servers as they avoid performance loss due to virtualization
- Physical servers can provide the best possible performance, but are complex to deploy and maintain
- ECS offer flexibility and scalability, but may not always meet the performance needs of core databases
- BMS address the performance limitations of ECS for core databases, offering dedicated physical servers with the benefits of cloud capabilities
- BMSs provide a balance between the performance of dedicated servers and the cloud’s advantages like online delivery, automatic management, and VPC interconnection

- Supports creation of private images from existing BMS for faster deployment and consistency
- Offers self-service application, simplified configuration, and full-lifecycle management
BMS Network
- Offers diverse network types, including VPC, high-speed network, enhanced high-speed network, user-defined VLAN, and InfiniBand network
- Provides network isolation between different network types
- Emphasizes Top-of-Rack (ToR) cabling for high-speed network connectivity
- Leverages NIC bonding to improve network performance and reliability
- Enables communication between BMSs and ECSs through VPC and InfiniBand networks
BMS Network: Virtual Private Cloud (VPC)
- A logically isolated, configurable, and manageable virtual network
- Provides secure and flexible connectivity to the internet and other cloud resources
- Offers advantages such as flexible configuration, high security, seamless interconnection, and high-speed access through dynamic BGP connections
BMS Network: High-Speed Network
