Study Notes
Image Management Service (IMS)
- Manages the entire lifecycle of images.
- Provides public, private, shared, and marketplace images.
Public Image
- A standard image provided by the cloud platform.
- Available to all users.
Private Image
- Only accessible to the user who created it.
Shared Image
- A private image shared with other users.
Marketplace Image
- A third-party image published in the Marketplace.
Auto Scaling (AS)
- Automatically adjusts resources based on demand.
- Relies on pre-configured AS policies.
- Consists of an AS group, AS configuration, and AS policies.
AS Architecture
- Adjusts compute resources based on service demands and AS policies.
- Uses scaling control to specify thresholds and schedules for scaling actions.
Scaling Control
- Specifies thresholds and schedules for scaling actions.
- Includes alarm-based, scheduled, and periodic policies.
Alarm-based Policies
- Configured based on alarm metrics like vCPU, memory, disk, and inbound traffic.
Scheduled Policies
- Schedule scaling actions to occur at specific times.
Periodic Policies
- Configure scaling actions to occur at scheduled intervals, specific times, or within time ranges.
AS Group
- Collection of instances and AS policies with similar attributes.
- Applies to the same scenario.
AS Configuration
- A template specifying instance specifications for the AS group.
AS Policy
- Triggers scaling actions to adjust the number of instances in an AS group.
Scaling Action
- Adds or removes instances from an AS group.
Cooldown Period
- Prevents repeated triggering of an alarm policy for the same event.
Bandwidth Scaling
- Automatically adjusts bandwidth based on configured policies.
Cloud Container Engine (CCE)
- Highly scalable, enterprise-class Kubernetes service.
- Used for running containers and applications.
Dedicated Host (DeH)
- A physical server dedicated to your services.
FunctionGraph
- Code execution service without server provisioning or management.
- Ensures high availability and scalability.
