CloudFoundry

 

PaaS stands for Platform as a Service. Platform services work as middle layer between underlying VM layer and the upper layer of application. For example a java runtime environment sits between the underlying linux virtual machine and the java application running on top of it.

PaaS is a type of cloud computing solution where one can launch a platform service without launching any virtual machine. Unlike the case for cloud environments like amazon EC2 where you need to launch a VM for installing any platform service such as java runtime environment or mysql database.

In the world of PaaS solutions, there are companies who provide a PaaS as a public cloud available all across globe over internet for general public consumption by anyone with a credit card. Amazon, Azure both have such services. Other bigger players are Google and Salesforce.

Like VMWare can be a data centre level solution alternative to the public IaaS cloud services like Amazon EC2, cloudfoundry similarly can be a data centre level solution alternative to the public PaaS cloud services. Cloudfoundry was created at VMware.

It can also become a public PaaS service competitor if one chooses to expose the data centre installation’s services available publicly over interfaces exposed on internet. And thats exactly what happened whereby cloudfoundry became the backbone of some of most prominent new age PaaS public cloud services of the market such as BlueMix or Centurylink AppFog.

So cloudfoundry quickly have grown to be the standard core of many derivative PaaS solutions built on top of it. Like Linux, there are distro’s of cloudfoundry which are all same at core but diverse at the presentation and management layers.

Hence cloudfoundry is not only one software but rather a framework or standard which once one learns can use for managing or operating on all those other solutions built on top of this framework.

We at Study9 understand this thoroughly, and hence our course is kept strongly tied to the core framework’s understanding. Once you go through this course, you will understand the core open source solution concepts deeply and thoroughly – which will help you in taking up a job of administering or working on any of the cloudfoundry derivatives – be it from IBM, HPE or Pivotal.

VMware was acquired by EMC, EMC was acquired by DELL. And Pivotal is a company formed by EMC and VMware together for some specific set of products and solutions. VMware being the original creator of VMware decided to give the reigns of cloudfoundry product management to this new entity called Pivotal.

Hence Pivotal Cloudfoundry is considered to be the most authentic distribution of the cloudfoundry considering it comes from the original creators.

Pivotal has launched various certifications both for companies who want to create distributions of cloudfoundry or solutions around cloudfoundry and also for people who want to be experts on cloudfoundry.

The people certification on cloudfoundry was first introduced as developer certification. Although the name spells developer, it meant to be a certification for developer people who want to use cloudfoundry as a platform provider for launching newly developed applications without worrying about data centre concepts like server, storage, networking etc. It is a certification curriculum to ensure that such people gather all required knowledge to make efficient and optimum use of the cloudfoundry. The developer certification did not explicitly require the person to be a developer though. A non developer could also learn from that curriculum and be an expert of using cloudfoundry.

A need for such a certification / training for administrators managing cloudfoundry was there but such a certification did not exist from Pivotal. Giving in to that demand, Pivotal has now launched cloudfoundry administrator certification as well.

So now, you have two certifications that you can do – cloudfoundry developer or cloudfoundry administrator.

We at Study9 are one of the earliest training companies providing cloudfoundry training worldwide through our online learning platform based training delivery mechanism. We have best in class industry trainers who have real time experience of developing on cloudfoundry and managing cloudfoundry implementations of colossal scale.

Our trainers will guide you through the process of learning all necessary concepts, procedures and tricks for you to become an expert of this new exciting domain with immense future ahead.

We have two separate training available for developer and administrator line of learning in both video and online training mode.

The trainings are covering good depth of concepts with a mix of our signature style of extensive practical oriented approach. By using these videos or live sessions you can build up your own lab environments in no time and can start learning cloudfoundry thoroughly.
