Introduction

Cloud Foundry is a stand-alone software package. Cloud Foundry has been developed under an open-source license, as an Open Application Framework as a Service. It is an open application Platform as a Service (PaaS) created under an open-source permit and hence anybody can avail it.

Cloud Foundry helps to quickly deploy, run, and scale the applications written in any language. It is found to be developer-friendly as it reduces the workload.

Initially considered in 2009, Cloud Foundry was planned and created by a group at VMware and it is now part of Pivotal Software. Cloud Foundry is utilized to compose codes. You can skip the complex configurations and operational tasks to focus on building the application. With the Cloud, Foundry developer can focus on what exactly matters.

1) Definition

Cloud Foundry is a computing system, an open-source platform. It enables developers to build cloud applications and host them. It is written in Ruby, Go, and Java. It has been developed in conjunction with VMware, EMC, and General Electric by Pivotal Software. The undertaking is represented by the Cloud Foundry Foundation, a nonprofit open-source project.

2) Benefits

  • Fast– With cloud foundry the user can reduce the time spent on configuration, deployment, and cloud infrastructure. You can use the time saved on software development. You can access everything from code to running software quickly.
  • Secure– The open-source project team guarantees a quick turn out of security patches in the light of vulnerabilities. It ensures that Cloud Foundry is secure for even the most sensitive mission-critical application development.
  • Integrate innovation– Cloud Foundry incorporates with your environment and tools, including CI/CD and IDEs, and easily brings a proven developer experience to Kubernetes with proficiency and polish.
  • Multitenancy-Cloud Foundry can deal with the utilization of numerous clients so that only authorized developers can update applications.
  • Application Utilization– To choose whether it is important to scale an application, Cloud Foundry gives an outline of how much resources (RAM, circle, CPU) are utilized by every application instance at the moment.
  • Restart failing application Instances– On the off chance that an application occurrence crashed under any conditions, Cloud Foundry will restart the crashed occurrence. 

3) Working

Step 1– The developer will deploy the application on Cloud Foundry by using the Cloud Foundry CLI interface.

Step 2– Cloud Foundry command line tells the cloud controller to create the record of the application.

Step 3– Cloud Foundry stores the application metadata on the cloud foundry data-base.

Step4-The Cloud Foundry CLI requests a resource match from the Cloud Controller. Before this process, the Cloud Foundry checks if the application file already exists in the resource cache. If yes, then the CLI will upload only those files that aren’t available.

Step 5– The Cloud Controller stores the application package in Blobstore.

Step 6– Cloud Foundry command line sends a command to the Cloud Controller to start the application.

Step 7– The Cloud Controller sends a staging request to Diego and Diego will schedule a Diego cell to run the staging task.

Step 8– Diego cell will generate and forward the output of the staging process.

Step 9– The task creates a droplet with the compiled app. The Diego Cell stores the droplet in the blob store.

Step 10– The staging process is completed.

Step 11– Diego starts the app on one or more Diego cells.

Step 12– Diego cell reports the status to the Cloud Controller.

Conclusion:

The Cloud Foundry Foundation is a nonprofit organization that aims at spreading awareness about Cloud Foundry. It was created in January 2015. It is neutral, holding the Cloud Foundry Intellectual Property i.e. trademarks, and copyrights. 

The “Cloud Foundry PaaS Certification Program” was announced by the Cloud Foundry Foundation in 2015  which outlines requirements to consider Cloud Foundry Certified provider.

Jigsaw Academy’s Postgraduate Certificate Program In Cloud Computing brings Cloud aspirants closer to their dream jobs. The joint-certification course is 6 months long and is conducted online and will help you become a complete Cloud Professional.
