Pivotal Cloud Foundry Interview Questions

1.      What is Pivotal Cloud Foundry?

Ans: Pivotal Cloud Foundry (PCF) is a platform as a service (PaaS) that enables developers to easily build, deploy, and scale their applications. It is based on Cloud Foundry open-source technology and provides additional features such as built-in security and networking.

2.      What are the key features of Pivotal Cloud Foundry?

Ans: Some of the key features of Pivotal Cloud Foundry include:

·        Platform as a Service (PaaS): PCF provides a platform for building, deploying, and scaling applications without the need to manage infrastructure.

·        Cloud-agnostic: PCF can be run on various cloud providers such as AWS, Azure, GCP and more.

·        Auto-scaling: PCF automatically scales applications based on demand.

·        Built-in security: PCF provides built-in security features such as role-based access control and network policy enforcement.

·        Networking: PCF provides built-in networking features such as service discovery and load balancing.

·        Developer experience: PCF provides a web console and command-line tools to make it easy for developers to build, deploy, and manage applications.

3.      How does Pivotal Cloud Foundry handle scaling?

Ans: Pivotal Cloud Foundry (PCF) automatically scales applications based on demand. Developers can configure the desired number of replicas for an application, and PCF will automatically adjust the number of replicas to meet that desired state.

4.      How does Pivotal Cloud Foundry handle networking?

Ans: Pivotal Cloud Foundry (PCF) provides built-in networking features such as service discovery and load balancing. It allows for easy communication between applications and services within the platform, and also allows for external communication via routes.

5.      How does Pivotal Cloud Foundry handle security?

Ans: Pivotal Cloud Foundry (PCF) provides built-in security features such as role-based access control and network policy enforcement. It also integrates with various security solutions to secure the applications running on the platform.

6.      How does Pivotal Cloud Foundry handle storage?

Ans: Pivotal Cloud Foundry (PCF) provides support for various types of storage such as local storage, network storage, and cloud storage. It also provides persistent volumes and persistent volume claims to manage the storage of data that needs to persist even after the application is deleted.

7.      How does Pivotal Cloud Foundry handle deployments?

Ans: Pivotal Cloud Foundry (PCF) uses a concept called "droplets" to handle deployments. Developers can push their applications to PCF, and PCF will create a droplet for the application. The droplet contains the application and all its dependencies, and can be deployed to one or more instances.

8.      How does Pivotal Cloud Foundry handle resource management?

Ans: Pivotal Cloud Foundry (PCF) allows developers to specify resource limits and requests for their applications, and will automatically schedule them on available resources. PCF also allows you to set quotas to limit the amount of resources that a project can use.

9.      How does Pivotal Cloud Foundry handle service discovery?

Ans: Pivotal Cloud Foundry (PCF) provides a built-in service discovery feature that allows applications to discover and communicate with other applications and services within the platform. Services in PCF are automatically assigned a URL, and can be accessed from other applications and services within the platform.

10.   How does Pivotal Cloud Foundry handle monitoring and logging?

Ans: Pivotal Cloud Foundry (PCF) provides built-in monitoring and logging features, such as the ability to collect and view application logs and metrics. It also allows you to integrate with external monitoring and logging solutions such as Prometheus and Elasticsearch.

11.   How does Pivotal Cloud Foundry handle CI/CD?

Ans: Pivotal Cloud Foundry (PCF) provides a built-in pipeline for continuous integration and continuous deployment. It allows you to configure and manage build, test, and deployment stages using the web console and command-line tools. It also supports integration with external CI/CD tools such as Jenkins and GitHub Actions.

12.   How does Pivotal Cloud Foundry handle security and compliance?

Ans: Pivotal Cloud Foundry (PCF) provides built-in security features such as role-based access control, network policy enforcement, and security contexts for applications and services. It also integrates with various security solutions to secure the applications running on the platform. PCF is also compliant with various industry standards such as SOC2, PCI-DSS, and HIPAA.
