Q

Infrastructure Services

A

Refer to the foundational capabilities and resources provided by the underlying infrastructure to support the deployment, management, and operation of containerized applications and Kubernetes clusters.

Key Info: Includes virtual machines, containers, storage, networking, and core capabilities.

17
Q

Lifecycle Management

A

Definition: Process of managing the entire lifecycle of an application, system, or service, including creation, deployment, maintenance, and decommissioning.

Key Info: TKG clusters in vSphere use the Cluster API for lifecycle management.

18
Q

Hypervisor

A

Definition: Software that enables multiple virtual machines to run on a single physical host, providing isolation and resource management.

Key Info: vSphere with Tanzu leverages the hypervisor for running VMs and containers.

19
Q

Supervisor Control Plane

A

Description: Component within the Supervisor Layer responsible for managing the control plane of Kubernetes clusters.

Key Info: Provides essential services and APIs for workload and resource management.

20
Q

Tanzu Kubernetes Clusters (TKG Layer)

A

Description: Layer where Tanzu Kubernetes clusters operate, running within virtual machines on the Supervisor layer.

Key Info: Enables deployment of containerized applications using Kubernetes technologies.

21
Q

vSphere with Tanzu consists of what layers?

A

Supervisor Layer
Supervisor Control Plane Layer
Tanzu Kubernetes Clusters (TKG Layer)

22
Q

vSphere consists of which layers?

A

Management Layer
Compute Layer
Application Layer
Network Layer
Storage Layer

23
Q

Container

A

Explanation: A container is a self-contained software package with an application and its dependencies. It’s isolated from the host system and encapsulates everything needed to run an app.

24
Q

Pod

A

Explanation: A Pod is the smallest unit in Kubernetes, hosting one or more containers. Containers within a Pod share resources like networking and storage, providing a way to group related app components.

25
Q

Role of RESTful API in vSphere with Tanzu

A

Provides a programmatic method to interact with infrastructure and services.

It facilitates automated management of virtual machines, networks, clusters (including Tanzu Kubernetes Grid), application deployment, configuration, monitoring, and integration with CI/CD pipelines.

26
Q

Load balancer virtual IP

A

Shared with development teams, who authenticate through vCenter single sign-on.

27
Q

Tanzu Runtime Services

A

A set of core services and capabilities for containerized applications. Tanzu Runtime Services simplify the complexities of managing and deploying cloud-native applications in diverse environments.
