    Study Notes

    Image Management Service (IMS)

    • Improves image management efficiency for ECSs by offering centralized image storage, version control, and management for both private and public images.

    Availability Zones (AZs)

    • If an AZ fails, ECSs automatically switch to another AZ in the same region to ensure service continuity.

    Cloud Eye

    • Monitors ECS resource usage, such as CPU, memory, and disk I/O, providing insights for optimization.

    Bare Metal Servers (BMSs)

    • The Operating System Installation feature allows users to install desired operating systems on BMSs.

    Memory-Optimized ECS

    • Ideal for applications demanding substantial memory resources, like databases or large-scale data processing.

    Cloud Eye

    • Primarily monitors ECS resource usage metrics and system performance.

    E-commerce Traffic Surges

    • Sudden traffic spikes can overwhelm systems, leading to website slowdowns, service outages, and potential loss of revenue.

    Elastic Volume Service (EVS)

    • The Cloud Backup and Recovery (CBR) service provides backup and recovery functions for data stored on EVS disks.

    BMS Security

    • Hardware Security Modules (HSMs) enhance data security and reliability for BMSs by securely storing cryptographic keys.

    E-commerce Payment Vulnerabilities

    • E-commerce enterprises face vulnerabilities like data leakage, financial fraud, and unauthorized access during the payment process.

    Rapid BMS Provisioning

    • BMSs can be rapidly provisioned by utilizing pre-configured templates and automated deployment tools, minimizing setup time.

    Cloud Backup and Recovery (CBR)

    • Provides backup and recovery functionality for EVS disks, ensuring data protection and resilience against failures.

    Real-time Massive Computing ECS

    • Compute-Optimized ECSs are efficient for applications needing real-time, large-scale processing, like scientific simulations or financial modeling.

    E-commerce Analytics

    • Insufficient analytics tools can lead to limited insights into customer behavior, impacting marketing strategies, product development, and overall business operations.

    BMS Deployment Flexibility

    • BMSs offer deployment flexibility allowing users to leverage dedicated resources in a dedicated environment for specific workloads.

    Virtual Private Cloud (VPC)

    • A Network Address Translator (NAT) gateway allows resources inside a VPC to communicate with the internet without requiring public IP addresses for each individual instance.

    Scaling Actions Cooldown Period

    • The cooldown period in scaling actions prevents excessive fluctuations in resource utilization by pausing adjustments for a set time, allowing systems to stabilize.

    Auto Scaling (AS) Bandwidth Adjustment

    • AS can adjust bandwidth allocated to instances based on traffic patterns and scaling policies.

    Cloud Container Engine (CCE)

    • A key feature of CCE is the ability to orchestrate and manage containerized applications across a cluster of nodes.

    Dedicated Host (DeH)

    • A Dedicated Host (DeH) provides enhanced security and performance isolation by ensuring that your instances run on dedicated physical servers, minimizing resource contention.

    FunctionGraph Cost Efficiency

    • FunctionGraph ensures cost efficiency by only charging for execution time and resources consumed. This pay-as-you-go model eliminates unnecessary spending on idle resources.

    Marketplace Images

    • These readily available images allow users to deploy preconfigured software stacks and applications without manual setup.

    Supported Image Formats

    • The cloud platform supports image formats like QCOW2, VHD, and RAW for importing.

    Image Conversion Tool

    • The Image Conversion Tool facilitates converting various image formats to supported formats before import.

    Shared or Marketplace Images for Startups

    • Shared or Marketplace images offer significant cost benefits for internet startups, enabling them to quickly launch applications without investing in infrastructure or image creation.

    Image Backup of Server Environments

    • An image can act as a snapshot of a server environment allowing you to restore it to a previous state in case of failure or for disaster recovery purposes.

    Periodic Backup Services

    • Cloud services like Cloud Backup and Recovery (CBR) and Object Storage Service (OBS) provide robust capabilities for scheduled backups.

    Auto Scaling (AS)

    • Auto Scaling (AS) dynamically adjusts resources based on pre-defined metrics to maintain application performance and availability, preventing performance bottlenecks and ensuring scalability.

    Traditional Batch Service Deployment Disadvantage

    • Traditional batch service deployment requires upfront resource allocation, which can lead to underutilization or overallocation leading to inefficient resource usage and increased costs.

    Public Image Purpose

    • Public images are primarily used for deploying common operating systems or software applications.

    Host Security Service (HSS) for Public Images

    • The Host Security Service (HSS) does not include the ability to enable root access to these images for security purposes.

    Private Image vs. Public Image

    • A private image is created by the user and is not shared publicly. This allows for customization and security-sensitive workloads.

    Marketplace Image Characteristics

    • Marketplace images are offered by third-party vendors and can be used for deployments of popular applications or software stacks.

    Shared Image Description

    • A shared image is created by a user and made available to other users within an organization. This allows for collaboration and sharing of resources.

    Migration Image

    • This type of image is specifically used for migrating data and applications from on-premises environments to the cloud.

    Unsupported Operating System in Public Images

    • The specific operating system not mentioned as part of the public images varies depending on the cloud provider and service.

    System Disk Image Contents

    • A system disk images usually includes the operating system, configuration files, and applications installed on the disk.
