Study Notes
Control Layer
- The control layer is responsible for managing and controlling the underlying cloud infrastructure.
- It enables provisioning of IT resources for creating cloud services.
- The control layer can be deployed on top of the virtual layer or on top of the physical layer.
- It receives requests from the service and orchestration layers.
- It provisions the required resources to fulfill the service request.
- Key functions of the control layer include resource configuration, resource provisioning, and monitoring resources.
Control Software
- Control software ties together the underlying resources and works with virtualization software to enable resource pooling, dynamic allocation of resources for services, and optimization of resource utilization.
- Control software provides a complete view of all resources in the cloud environment, enabling centralized management of IT resources.
- There are two main types of control software: element manager and unified manager.
Element Manager
- Infrastructure component vendors may provide element managers as built-in or external software.
- Element managers are necessary to manage infrastructure components independently.
Key Tasks Performed by Element Manager
- Enables initial component configurations and modifications: installing guest OS, configuring zoning, security settings, VLANs, RAID, and LUN masking.
- Allows expansion of resource capacity: detecting newly added resources and adding them to an existing pool.
- Enables problem identification and troubleshooting.
- Monitors infrastructure components for performance, availability, capacity, and security.
Unified Manager
- Unified Manager provides a single management interface for configuring and provisioning resources for applications and services.
- Exposes APIs that can be integrated with the orchestration layer to automate service provisioning.
- Enables adding or removing infrastructure resources to an already provisioned service.
- Performs compliance checks during resource configuration.
- Provides a dashboard showing resource configurations and utilization, allowing administrators to perform monitoring, reporting, and root cause analysis.
Key Phases for Provisioning Resources
- Resource discovery allows the unified manager to learn about available resources for service deployment.
- It provides visibility to each resource and enables central management of cloud infrastructure resources.
- Resource pooling allows resources to be grouped and managed together, making it easier to provision and manage services.
- Resource provisioning is the process of allocating resources to services and applications.
- Resource management techniques include dynamic allocation, resource optimization, and monitoring and reporting.
