Real World Vagrant - Automate a Cloudera Manager Build هذه الدورة تدرس باللغة الإنجليزية

تفاصيل الدورة

Note : This course is built on top of the "Real World Vagrant For Distributed Computing - Toyin Akin" course

"NoSQL", "Big Data", "DevOps" and "In Memory Database" technology are a hot and highly valuable skill to have - and this course will teach you how to quickly create a distributed environment for you to deploy these technologies on. 

A combination of VirtualBox and Vagrant will transform your desktop machine into a virtual cluster. However this needs to be configured correctly. Simply enabling multinode within Vagrant is not good enough. It needs to be tuned. Developers and Operators within large enterprises, including investment banks, all use Vagrant to simulate Production environments. 

After all, if you are developing against or operating a distributed environment, it needs to be tested. Tested in terms of code deployed and the deployment code itself.

You'll learn the same techniques these enterprise guys use on your own Microsoft Windows computer/laptop.

Vagrant provides easy to configure, reproducible, and portable work environments built on top of industry-standard technology and controlled by a single consistent workflow to help maximize the productivity and flexibility of you and your team.

This course will use VirtualBox to carve out your virtual environment. However the same skills learned with Vagrant can be used to provision virtual machines on VMware, AWS, or any other provider.

If you are a developer, this course will help you will isolate dependencies and their configuration within a single disposable, consistent environment, without sacrificing any of the tools you are used to working with (editors, browsers, debuggers, etc.). Once you or someone else creates a single Vagrantfile, you just need to vagrant up and everything is installed and configured for you to work. Other members of your team create their development environments from the same configuration. Say goodbye to "works on my machine" bugs.

If you are an operations engineer, this course will help you build a disposable environment and consistent workflow for developing and testing infrastructure management scripts. You can quickly test your deployment scripts and more using local virtualization such as VirtualBox or VMware. (VirtualBox for this course). Ditch your custom scripts to recycle EC2 instances, stop juggling SSH prompts to various machines, and start using Vagrant to bring sanity to your life.

If you are a designer, this course will help you with distributed installation of software in order for you to focus on doing what you do best: design. Once a developer configures Vagrant, you do not need to worry about how to get that software running ever again. No more bothering other developers to help you fix your environment so you can test designs. Just check out the code, vagrant up, and start designing.

Here I present a curriculum as to the current state of my Cloudera courses.

My Hadoop courses are based on Vagrant so that you can practice and destroy your virtual environment before applying the installation onto real servers/VMs.

For those with little or no knowledge of the Hadoop eco systemUdemy course : Big Data Intro for IT Administrators, Devs and Consultants

.

I would first practice with Vagrant so that you can carve out a virtual environment on your local desktop. You don't want to corrupt your physical servers if you do not understand the steps or make a mistake.Udemy course : Real World Vagrant For Distributed Computing

.

I would then, on the virtual servers, deploy Cloudera Manager plus agents. Agents are the guys that will sit on all the slave nodes ready to deploy your Hadoop servicesUdemy course : Real World Vagrant - Automate a Cloudera Manager Build

.

Then deploy the Hadoop services across your cluster (via the installed Cloudera Manager in the previous step). We look at the logic regarding the placement of master and slave services.Udemy course : Real World Hadoop - Deploying Hadoop with Cloudera Manager

If you want to play around with HDFS commands (Hands on distributed file manipulation).Udemy course : Real World Hadoop - Hands on Enterprise Distributed Storage.

.

You can also automate the deployment of the Hadoop services via Python (using the Cloudera Manager Python API). But this is an advanced step and thus I would make sure that you understand how to manually deploy the Hadoop services first.Udemy course : Real World Hadoop - Automating Hadoop install with Python!

.

There is also the upgrade step. Once you have a running cluster, how do you upgrade to a newer hadoop cluster (Both for Cloudera Manager and the Hadoop Services).Udemy course : Real World Hadoop - Upgrade Cloudera and Hadoop hands on
