Module 3: Modern Data Center Environment (SDDC + Modern Data Center Architecture) Flashcards
What is SDDC (software defined data center)?
architectural approach to IT that extends virtualization to all data center resources and services
What are the 4 planes of SDDC?
Service Plane
Management Plane
Control Plane
Data Plane
order from bottom to top in stack
What is the service plane of SDDC?
allows user to autonomously request services from catalog
What is the management plane of SDDC?
used to perform admin operations like configuring system/changing policies
What is the control plane of SDDC?
provides programming logic and polices that data plane follows to perform operations (asset discovery, pooling, provisioning etc.)
What is the data plane of SDDC?
performs data processing and IO operations
How does SDDC process work?
architecture decouples control plane from data plane - control functions of infrastructure sent to external software controller
What does the software controller in SDDC do?
provides GUI for admins to manage infrastructure/configure policies
automates many management operations
provides APIs for external management and orchestration
What does SDDC architecture enable end users to do?
users can view and access IT resources from self-service portal - provides catalog that lists set of services for users
service request forwarded to software controller that provisions appropriate resources
What are the 5 logical layers of Modern Data Center Architecture?
physical infrastructure
virtual infrastructure
software-defined infrastructure
orchestration
services
What are the 3 cross-layer functions of Modern Data Center Architecture?
business continuity
security
management
What does Modern Data Center Architecture do?
ensures infrastructure can be transformed into a cloud infrastructure and connected to external cloud for hybrid/multi strategy
What is the services layer of MDCA?
includes services catalog that presents information about all IT resources being offered
What is the orchestration layer of MDCA?
provides workflows for executing automated tasks to perform a business operation
What is the physical infrastructure layer of MDCA?
forms foundation layer of the data center
