Future of Ansible and OpenShift Training

Ansible is a supportive open source mode or system that offers simple solutions to complex situations. It can help with

  • Configuration management
  • Application deployment
  • Task automation
  • IT orchestration

It is an advantageous technique that allows creating a series of a machine, explains the configuration of these machines and how to operate the best. It also manages the existing server with ease. It is further beneficial because it is

  • Simple to install, easy to use, and gets started fast. It uses a simple syntax (YAML), human eligible data serialization language called Playbooks. It does not require any special coding skills and can be handled easily by reading playbooks.
  • Agentless– Ansible does not require any software or additional portal that is usually required to install before you want to automate a process. So, without setting a separate management infrastructure, it minimizes the efforts and gets started right away.
  • Powerful and flexible- Ansible has some powerful characteristics in the form of 100 modules, that helps to execute the most complex IT workflow easily. It helps to manage- infrastructure, networks, operating systems & services that is being already employed. In all, it allows integrating the entire application environment, irrespective of where it is stationed.
  • Efficient – it can be easily customized as per the requirement. It does not require any extra application on the server which means you are saving space for other resources.

Ansible is usually clubbed with other configuration management tools like Puppet, Chef, etc.  Apart from configuration management, Ansible can be applied for different functions like-

  • Provisioning
  • Application Deployment
  • Security & Compliance
  • Orchestration

With Ansible being strongly backed by Red Hat, and seeing the series of application, it is advisable to take Ansible training. Ansible has a long and promising journey, devoting time in training in Ansible would be great for your career.

OpenShift

RedHat OpenShift is a cloud development platform as a Service (PaaS). It is a versatile, all-around open source container application platform that allows developers to

  • Create
  • Test
  • Conduct their applications
  • Redistribute them to the cloud

OpenShift provides support to many languages like Node.js, Python, Ruby, PHP, Perl, and Java. It is also expandable and can supplement support for other languages too. It can also, in cases of increase in demand, elevate the resources field for the application and prevent any lapse in performance. It provides mobility and flexibility through the Delta Cloud API, to allow you to migrate redistribution to other cloud computing vendors.

RedHat OpenShift is accessible in 4 models

  1. OpenShift Container Platform

OpenShift Container Platform is a private PaaS (Platform as a Service) for companies that distribute and manage OpenShift on their personal on-campus hardware or on the base of a certified cloud provider. It is executed as an aggregation of Docker-based Application containers controlled via Kubernetes orchestration/management. They all conduct on an operating system base of RHEL- (Red Hat Enterprise Linux).

  1. OpenShift Online

OpenShift online was introduced in 2011 for individual and team developers, who want to approach it as a public cloud service. It is based on, on-demand consumption model introduced on public cloud platforms like AWS (Amazon Web Services).

It took a step ahead in 2017, by furnishing a container-based platform, which can be accessible from any web browser, command line and IDE. It extended its support for local development, helping programmers to distribute a functional OpenShift cluster on their regional workstations. It also helps in port forwarding, that allows the developers to employ remote services like they are operating locally.

It is constructed along the lines of OpenShift Container using the same code and offers redistribution platform for OpenShift.io.

  1. OpenShift Dedicated

OpenShift Dedicated, endeavors companies to operate a single-tenant OpenShift atmosphere on a public cloud, with the help of Docker and Kubernetes orchestration technologies. This public cloud is handled by Red Hat. In 2015, when it was launched, it operated only on AWS, but now it has added Google Cloud Platform also.

  1. io

OpenShift.io launched in 2017, is a costless, open source additive to OpenShift Online. United they offer an integral accession to DevOps. The DevOps are applications that consolidate tools for developer teams to create and display microservices-based applications.

OpenShift.io also facilitates machine learning system and a Linux container environment, conducive for developers to arrive at design decisions. It also contains many open source development technologies like- Eclipse Vert.x, Spring Boot, WildFly, Swarm, Performance Co-Pilot, OpenJDK, Jenkins, and fabric8.

Why take OpenShift training

There is an increase in the container used in the development and production of apps. Services like OpenShift facilitates means to manage and automate a large number of containers. Incorporating OpenShift reduces the manual management of containers.

OpenShift can also aid IT organizations to replace traditional applications with modern micro-services platform. These features are quickly deployed to the mobile-first approach for organizations, producing tablet and smartphone apps.

By enrolling for OpenShift training you can enhance your career since there is a good demand in this field. The mobile application has a great future ahead and OpenShift is all about developing and managing Apps.

6 Things You Do Not Know About Ansible

Ansible is probably one of the most powerful IT automation tools available today. It’s easy to use yet, gives powerful results. Ansible helps organizations to manage their IT environment and get the best support network. Ansible is basically a tool that is useful for servers and does easy operations. One of the best benefits of using this tool is however that it teaches people to think about the environment they are working in and get the knowledge on how it works. It is one worthy network automation tool that offer several network requirements.

Ansible runs on Linux and Mac OS X systems but is also useful in managing other systems like Windows BSD, cloud service platforms, and other network devices. Here is the list of things that you do not really know about Ansible. These are the eye-openers as to how many maximum benefits one can attain by using Ansible.

1. Ansible is used to manage other things than simply servers – Most of the Ansible usage is to configure and manage the servers. However, not many people know how vast it is and how it can be used for different functions too. Any SSH interface or an API can be managed with Ansible. There are different modules in its library that talks to cloud platforms, F5 load balancers, etc. The modules are helpful for multi-server rolling upgrades that require coordination.

2. Ansible helps to mix on-premise and cloud inventories easily – Ansible consists of cloud inventory sources that have the dynamic process. It helps to retrieve the latest list of servers from Azure, Amazon, Rackspace, etc. Ansible has the built-in mechanism that helps to handle the cloud mixing and static inventories.

3. Ansible helps to write playbooks in JSON – JSON is a subset of YAML, hence one can write playbooks in JSON formats too. Generally, people use YAML as the text file format for Ansible since it’s easily readable by humans and also machines.

4. Ansible is useful for managing the Windows application and software – There is one extra plug-in that used to run Powershell scripts on the Windows, one can use WinRM protocol to run the scripts. There has been growth in the Windows modules library and plug-ins is being made for easy usability.

5. Ansible has vast and growing plug-in infrastructure – Ansible is flexible in use hence it can be extended through several ways. One of the most common ways followed is to write a custom module. There are series of interesting Python plug-in interfaces that one can use to build a good custom behavior. Some of its modules are Dynamic inventory sources, callback plug-in, and custom filter plug-in.

a. Dynamic inventory sources – with the help of a customer CMDB, you can use the source of truth environment. One can write a custom inventory plug that helps to pull the hosts and groups from existing databases.

b. Callback plug-ins – these are very powerful plug-ins. They are especially used to trigger the notifications, for example, posting to the messages on to the chat tools, react in flexible ways, signal the monitoring events and so on.

c. The Custom filter plug-ins help to handle complicated data structures in the playbooks. They allow you to manipulate the data in varied ways and it can help simplify the playbook by offloading small python plug-in.

6. The user has control on the playbook – The use of Ansible requires a lot of technical knowledge. The playbooks in the Ansible always run from the top to the bottom, this is the usual process especially when the playbook is tested and running. But for checking during the development requires skipping certain sections of the playbook.

Ansible is a very flexible tool and it’s an extensible automation tool that can be used in a lot of different environments’. There are several ideas and tools that help you to customize and configure Ansible working to give automation according to your needs.

New Level of Automation with Ansible

Already heard about Ansible and what’s it capable of? No! Well then know that it’s a simple yet super-effective automation tool that needs no agent and used widely for a number of projects till date, taking the world of automation to a whole new level. Yes, it is still BASH that will be the very basic requirement for shell scripting for any sysadmin; but still, there’s no denying that Ansible has become a smooth yet crucial part of becoming successful in both as a developer and as a sysadmin. Keep on reading to know what Ansible offers in store for the industry of automation.

Easy Reaching the Desired State

Suppose, a server is in a state named as ‘X’, and a script is written for changing its position to another state, named as ‘Y’. But when you’ll run the script twice, it will fail to work as it will automatically start from the state Y, failing the very purpose of the script for which it is written. However, with Ansible, a declarative, easy to point and simple coding structure, getting to the desired state won’t be a problem at all. After all, Ansible is all about reaching the desired state fast, where every task is defined in ways, irrespective of the context of the initial state.

Simultaneous Working On Multiple Servers

When it comes to working on multiple servers at the same time, who can be better than Ansible again! Yes, leaving even the efficiency of the Python code behind, Ansible offers simple commands, using shell modules, for reporting git branch, upon which all the servers stand. While for day-to-day tasks, python codes can be not-so-productive, with Ansible, even working with hundreds or thousands of servers simultaneously become easier.

Report Changes and Dry Run

Though going from the very desired state of itself may sound not so important or trivial, but this particular task is used as ‘dry run’ for reporting deviations or any change from the desired state. Periodically used also for enforcing some policies, the Ad-Hoc commands offered by Ansible can be run easily for creating a directory. Not only for creating a directory, reporting the necessary changes in the commands if the command fails to run can also be done quickly in Ansible.

Creating Readable Playbooks

Thinking about creating readable playbooks? Why wait then when you have Ansible by your side! If BASH scripts, written by others, gives you a hard time in recovering your readability power, then why not try the Ansible playbooks as deploying a highly available complex cluster, they see to the matter that the playbooks remain both readable and simple.

Easy Orchestration

With Ansible doing serial execution to parallel and delegated execution and others are very much possible. Be it going to the load balancer and removing a server from it or doing some changes to the server, and then again placing it back in the load-balancer, you can do anything with Ansible at your service.

Though as simple as BASH, Ansible is a lot more than BASH. Anyone becoming proficient in Ansible, cannot only write super easy-to-read Ansible playbooks instead of the complex shell scripts but can also use the Ad-Hoc commands just as they use an interactive bash shell for creating a whole new smoother and better automation.

What is Ansible?

IT Industry is always looking for better solutions when it comes to finding a better technology. Ansible seems to have answered many people’s problems. Aimed to remove toiling from the user’s work life whilst intensely improving the volume of a task to be changed in size or scale, steadiness, and dependability of an IT atmosphere, Ansible is an open-source IT automation engine. Given its growing reputation, it is a must to look into the finer details of Ansible. Here is an in-depth analysis.

The talk about Ansible has been about its abilities to automate. Ansible can be used to automate three kinds of responsibilities:

  • Provisioning: Ansible helps in setting up the several servers that can be needed in an infrastructure.
  • Management of Configuration: It helps in changing the disposition of either an application (apk files) or OS (Operating System) or device. It has the ability to start and stop services. It can also install or update apps. Ansible also applies security policies along with running a vast range of other configuration tasks.
  • Application disposition: By running automation in the placement of internally created apps to the production structures, DevOps is made a lot easier.

Ansible a perfect solution

Ansible automates IT environments. Being hosted on old-style plain metal servers or on virtualization stages or being in the cloud does not matter. Ansible has the capacity to automate the configuration of a vast variety of systems and machines. The likes of databases, firewalls, storage devices, etc. are all included.

Ansible, better than its competitors?

In this day and age, the options of IT automation tools are plenty. When there are developed ones like Puppet and Chef already available, the market may seem a bit rough for Ansible. That was the overall prediction but that has not been the case at all. Ansible’s simplistic nature has made it differentiate itself from customers. Michael DeHaan is the originator of Ansible. He is a highly experienced man in the field of configuration management tools. That gave him a huge bonus when he was developing Ansible because he really made the process of using automation tools simpler. His target was to create a tool that would be easy to remember even when not used for a very long time. That has indeed become Ansible’s unique quality.

By the usage of YAML, a meek configuration language, Ansible was made to be a lot easier to use compared to its direct market rivals Puppet and Chef, both of which use the programming language Ruby, something way more complicated. This has made Ansible particularly attractive to system administrators. DeHaan also made Ansible’s deployment a lot less complex by making it agentless – which means that Ansible does not require the installation of an agent on every system that needs to be managed as is the case with Puppet and Chef. Ansible’s needs for running smoothly are the availability of SSH, Python on Linux servers and PowerShell on Windows servers.

Ansible Playbooks

Playbooks are easy to write and preserve. Most operators become fruitful with Ansible after spending as little as a few hours. The tools used by Ansible are the same tools anyone has already used on a daily basis. Playbooks are written in a normal dialect so they are very simple to change and manage.

Ansible is a better fit for users who generally work on Linux systems. They will also suit those better who prefer using SSH all the time. Ansible is the best solution for configuration management accessible. It’s planned to be negligible in failure. It is naturally reliable, protected, and delivers on a consistent basis. Most important is that demands a low level of understanding compared to its competitors. Its simplicity makes it stand out.

Automate Application Updates with Ansible

Ansible is a configuration management tool that allows a user to do a lot of things like to arrangement of EC2, configuring Operating System and the installation of software on AWS. The file where all of the settings are written in the playbook. Ansible automates performing the jobs written on the playbook to numerous servers. The number of servers does not matter. Even if the number is as high as two hundred (even more). This is done so that the user does not have to toil in the process of setting up the installation commands as well as the configuration commands on every single server.

The Need for Automate Application Updates

Developers and systems administrators have often found a common problem while working to automate the rolling out of application updates. This common problem is automating the web alongside the SaaS architectures that tend to last more than an individual machine. The more important thing in hand is the management of those particular systems in an efficient manner that helps in the preservation of uptime. This is specifically serious in high-traffic web sites and other such services. When we look at the automation structuring, it is easy to see that itself it seems to be insufficient to model the activities that occur on an individual machine at a time or even all courses of machines at a particular time. This is due to the fact that concurrent updates can cause outages.

Updates On Live Infrastructure

Executing updates on live infrastructure is a nightmare for any IT team. That one particular problem has been the cause for numerous sleepless nights for god know how many IT professionals. And it isn’t a task that an individual can carry out, the whole team gets stuck in the office. It is not only a tedious process, it also demands complete focus and attention. One mistake can lead to customers having problems in receiving data. Their orders can get dropped, their data can get permanently lost or even worse – it can damage the company name. Therefore, such a nervy situation needs to be handled carefully. Innovations need to be made to avoid such situations. Ansible just might be the answer to this problem. Ansible is a configuration, app placement and transposition resolution that delivers influential tools to roll out multi-tier apps. These apps can be rolled out both on physical infrastructure or the more advanced cloud infrastructure.

How Ansible Solves Problems

How does Ansible do that? Ansible does that by using smart and effective techniques. Armed with a server-less and agentless solution (the only exception being the usage of SHH) that can superbly regulate the time and location of order operations. It knows and facilitates each order operations by allocating them to particular machines. It’s also predominantly decent at the roll-out of multi-tier apps.

It is, in fact, better at the implementation of those crucial rolling updates and in making them a “push button” process. Ansible styles this easily by having a push-based, plainly well-ordered system that has the ability to talk to a group of hosts. On behalf of someone else, t can also talk to another. It also can move on to other groups, to perfect all kinds of configuration, application deployment and the other roll out procedures.

Ansible is of course of more use than just rolling updates. Its list of commendable utilities includes configuration management, the running of shell commands on remote nodes and other similar but basic application rollouts.

Anyone looking for an automation tool should fancy Ansible as it would be a superior fit in a bigger and consistent infrastructure. Not only is it fast, it also does all jobs over SSH without requiring installation. Now with Automate Application Updates, Ansible’s reputation is only set to rocket.
