What is Pivotal Cloud Foundry (PCF)?

Pivotal Cloud Foundry, also known as PCF, is a distribution of the open-source Cloud Foundry platform that includes additional features and services that expand the capabilities of Cloud Foundry and make it easier to use. IaaS platforms like Google Cloud and AWS have built and configured templates that make it easy to deploy enterprise PCF as a PaaS solution on top of their cloud-based infrastructure products.

Key takeaways

  • Cloud Foundry is a multi-cloud platform used to support the development, management and continuous delivery of software applications
  • The main purpose of Pivotal Cloud Foundry is to provide the underlying infrastructure and environments that organizations need to facilitate the continuous delivery of software updates, manage the application life cycle and streamline the development, deployment, and scaling of web-based applications.
  • PCF speeds up software delivery and makes it easy to scale underlying application infrastructure with a growing base of users.
  • Sumo Logic's PCF integration takes full advantage of the aggregator Firehose, capturing the continuous stream of log data from PCF with a specialized Pivotal Cloud Foundry Nozzle tool.

PCF components and functions

Cloud Foundry is a multi-cloud platform used to support the development, management and continuous delivery of software applications. It can be deployed on top of an IaaS tool, such as Amazon Web Services (AWS), vSphere or OpenStack, and provides a set of features and specialized functions that help organizations reduce the cost and complexity of configuring the underlying platform for their applications.

PCF is a platform used to deploy next-generation apps. PCF is a cloud-native and open-source technology that can rapidly deliver experiences to end users. Also, PCF uses containers. The original container version for PCF predates Docker and was called warden, but was changed to the garden.

The main purpose of PCF is to provide the underlying infrastructure and environments that organizations need to facilitate the continuous delivery of software updates, manage the application life cycle and streamline the development, deployment, and scaling of web-based applications. PCF is a distributed system with many components that play different roles in this process:

BOSH: BOSH is a deployment manager tool originally developed for use with Cloud Foundry, but it can also be used outside of PCF to deploy a Kubernetes cluster. This application provides an interface between PCF and a chosen IaaS platform, enabling the PCF platform to be deployed in any cloud environment. BOSH uses IaaS-specific cloud configurations (like those created by AWS and Google Cloud) and the baseline deployment configuration for PCF to map resources between PCF and the IaaS provider accurately.

Ops Manager: The Ops Manager is a web-based graphical interface that helps automate tasks and supports the deployment of PCF into IaaS environments. It includes additional features like monitoring solutions that can be imported and configured before deployment.

User Account and Authentication (UAA) Server: The UAA component of PCF controls identity and access management on the server. PCF operators can use this tool to create, configure and manage user accounts, including administering roles-based access and generating authentication tokens for client applications.

The Gorouter: Written in the Go programming language, Gorouter is used by PCF to handle incoming requests or commands from operators or developers. Depending on their origin, requests may be routed through the Cloud Controller API or directly from users to applications running on the PCF deployment. Gorouter communicates with Diego to keep track of application instances and manage load balancing.

The Cloud Controller:The Cloud Controller centralizes API endpoints where developers and operators can send commands to PCF and its deployed applications. This includes all types of queries and requests, including staging applications, stopping or starting an application, and collecting information on the operation of currently deployed applications.

Diego - Diego is the container orchestration system for PCF deployments. Diego orchestrates the deployment of containers within PCF using three main components:

  • Diego Brain receives incoming requests, assigns them to cells and schedules them for execution
  • Diego Cells are virtual machines that run containers. Containers represent an allocation of memory and virtual cores that can be used to complete a task.
  • Database VM is a live database that monitors new requests, stores information about requests that have been received and updates the status of requests as they are completed.

Loggregator—PCF's Loggregator aggregates and streams computer-generated log and event files and metrics from all of PCF's infrastructure components and deployed applications. These logs are combined into a single data stream known as the PCF Firehose.

Pivotal Cloud Foundry (PCF) benefits for developers

With PCF, organizations can improve the efficiency and speed with which they build, deploy and operate the software. PCF speeds up software delivery and makes it easy to scale underlying application infrastructure with a growing base of users. PCF is highly automated, easy to install, and runs on any public or private cloud, so organizations can run their applications wherever they choose and scale them across infrastructure targets.

Sumo Logic streams PCF data in real-time

Sumo Logic's PCF integration takes full advantage of the aggregator Firehose, capturing the continuous stream of log data from PCF with a specialized Pivotal Cloud Foundry Nozzle tool. With Sumo Logic, users of PCF can funnel aggregator data through a single nozzle that streams network and event logs along with metrics directly to the Sumo Logic platform, where machine learning techniques drive data analysis that yields operational intelligence and business insights.

FAQs

How does PCF aid in the management of microservices architecture?

With PCF, developers can focus on building and coding their microservices without worrying about the underlying infrastructure. PCF offers features like service discovery, load balancing, and auto-scaling, which streamline the deployment and operation of microservices. Additionally, PCF supports continuous delivery practices, allowing teams to quickly and efficiently roll out updates to their microservices-based applications. Overall, PCF enhances the agility, scalability, and reliability of microservices architecture, making it easier for organizations to embrace and benefit from this modern approach to application development.

Can PCF support hybrid cloud environments effectively?

PCF can support hybrid cloud environments effectively by providing a consistent platform for deploying and managing applications across public and private clouds. With PCF, organizations can leverage the flexibility of hybrid environments to optimize resource usage, enhance scalability and improve overall operational efficiency.

What are some common challenges faced during a PCF deployment?


Challenges may arise in navigating the deployment of PCF across various cloud platforms, such as Google Cloud, Amazon Web Services (AWS), Microsoft Azure, and others, and in ensuring smooth application migration to the cloud environment.
