Let’s start discussion what I learn from these great personalities in yesterday

What is Automation?

Automation is the creation and application of technologies to produce and deliver goods and services with minimal human intervention. The implementation of automation technologies, techniques and processes improve the efficiency, reliability, and speed of many tasks that were previously performed by humans.

Advantage of Automation

• More efficient production
• Avoid Boring , repetitive jobs
• Can enable a shorter working week
• Can Improve safety and remove risk of human error
• Improve operating efficiencies & many more

There are many tools available for automation one of them is Ansible

Ansible

Ansible is an open-source software provisioning, configuration management, and application-deployment tool enabling infrastructure as code. It runs on many Unix-like systems, and can configure both Unix-like systems as well as Microsoft Windows. It includes its own declarative language to describe system configuration. Ansible is agentless, temporarily connecting remotely via SSH or Windows Remote Management to do its tasks.

Features of Ansible

Simple

• Human readable automation
• No special coding skills needed
• Tasks executed in order
• Get productive quickly

Powerful

• App deployment
• Configuration management
• Workflow orchestration
• Orchestrate the app lifecycle

Agentless

• Agentless architecture
• Uses OpenSSH and WinRM
• No agents to exploit or update
• Predictable, reliable and secure

Ansible Tower

Ansible Tower is a web-based solution that makes Ansible even more easy to use for IT teams of all kinds. It’s designed to be the hub for all of your automation tasks.

With Red Hat Ansible Tower you can centralize and control your IT infrastructure with

Visual Dashboard

The Ansible Tower dashboard provides a heads-up NOC-style display for everything going on in your Ansible environment.

REAL-TIME JOB STATUS UPDATES

Within Ansible Tower, playbook runs stream by in real time. As Ansible automates across your infrastructure, you’ll see plays and tasks complete, broken down by each machine, and each success or failure, complete with output. Easily see the status of your automation, and what’s next in the queue.

MULTI-PLAYBOOK WORKFLOWS

Ansible Tower Workflows allow you to easily model complex processes with Ansible Tower’s intuitive workflow editor. Ansible Tower workflows chain any number of playbooks, updates, and other workflows, regardless of whether they use different inventories, run as different users, run at once or utilize different credentials.

You can build a provisioning workflow that provisions machines, applies a base system configuration, and deploys an application, all with different playbooks maintained by different teams

SCALE CAPACITY WITH TOWER CLUSTERS

Connect multiple Ansible Tower nodes into a Ansible Tower cluster. Ansible Tower clusters add redundancy and capacity, allowing you to scale Ansible automation across your enterprise, including with reserved capacity for certain teams and jobs, and remote execution for access across network zones. Current Ansible Automation architecture can scale to 200K nodes with 20 cluster nodes.

INTEGRATED NOTIFICATIONS

Stay informed of your automation status via integrated notifications. Notify a person or team when your job succeeds, or escalate when jobs fail. Send notifications across your entire organization at once, or customize on a per-job basis.

Connect your notifications to Slack, Hipchat, PagerDuty, SMS, email, and more — or post notifications to a custom webhook to trigger other tools in your infrastructure

SCHEDULE ANSIBLE JOBS

Playbook runs, cloud inventory updates, and source control updates can be scheduled inside Ansible Tower — run now, run later, or run forever.

MANAGE AND TRACK YOUR ENTIRE INVENTORY

Ansible Tower helps you manage your entire infrastructure. Easily pull your inventory from public cloud providers such as Amazon Web Services, Microsoft Azure, and more, or synchronize from your local OpenStack cloud or VMware environment. Connect your inventory directly to your Red Hat Satellite or Red Hat CloudForms environment, or your custom CMDB.

COMPREHENSIVE REST API AND TOWER CLI TOOL

Far from being limited to just the user interface, every feature of Ansible Tower is available via Ansible Tower’s REST API, providing the ideal API for a systems management infrastructure to build against.

In this session we used all features to solve real industry use-case like-

• Provisioning
• Configuration Management
• Continuous Delivery
• Network Automation
• Security Automation
• Orchestration & many more.

All the use-case teach by SREEJITH ANUJAN SIR with live practical.

It was amazing session , Thank you so much sir to give your precious time to us.
