How to Automate AWS Management with AWS CLI

AWS

Introduction

Since their establishment back in the mid-’00s, Amazon Web Services have been one of the leading cloud-computing platform providers. The company, which is also a subsidiary of Amazon, has been in charge of facilitating businesses with ginormous computational capabilities such as database creation, storage abilities, content delivery services, account management, application development, etc. It is owing to these services that numerous businesses have been able to grow and flourish beyond their wildest expectations.

 

The AWS Management Console

Being packed with tools beyond comparison, the Amazon Web Services have certainly enabled businesses to flourish by the means of uncomparable computational capabilities. However, the simultaneous availability of such services could also be the cause of mayhem if not managed with the right tools.

In order to counter such a situation, the company provided its clients with a management console, capable of countering all such situations. By means of the AWS Management Console, the company provides its clients with an extensive set of tools that can be used right from within your computer or even your phone.

The console allows you to securely access all the web services by the means of a web-based portal. This allows you effortlessly manage your entire account and take care of the principal requirements such as registering or creating new accounts, managing registered accounts, building newer applications, configuring preloaded services, collecting data regarding services, troubleshooting issues faced, etc.

 

Automation of the AWS Management Console

However, the Management Console also brings with itself, a select set of shortcomings. As a company or organization flourishes and expands, they naturally require business owners and administrators to split the processes among smaller equivalents to efficiently manage your business.

One of the easiest and customary methodologies implemented in executing this idea is the creation of additional accounts. With the help of the additional accounts, you can control the individual work processes effortlessly.

Post-creation of such accounts can surely allow you to manage your business in a more efficient manner. However, creating these accounts is, by no means, a walk in the park. It is a monotonous, time-consuming and irksome task at the very least. This results in the waste of valuable time that could be used to facilitate the completion of other tasks.

To help sort this issue, the company introduced the AWS Command Line Interface. The CLI is a tool that enables you to manage your AWS services by the means of a terminal session.

The terminal allows you to control and automate the services simply by the help of a command line interface and some scripts.

 

The Primary Application of AWS Management Automation

By implementing the Management Console, users can easily get access to numerous multifaceted applications. , when used in conjunction with automation, can enhance the effectiveness of your services. However, the primary use of automation is in the field of account creation.

It is by the means of the AWS Services Catalog that users undertake the process of account building. With the help of the AWS Service Catalog, the AWS Lambda, and AWS Organizations, you can easily facilitate the creation of newer accounts. Apart from this, the Lambda feature can also be used to implement solutions, that include:

1.Creating new AWS accounts.

2.Creating organizational units within the root account.

3.Refactoring the newly created accounts and transferring them from the organization root to within the organizational unit.

The Other Applications of AWS CLI Automation

Apart from the creation of newer accounts, the command line is also utilized in simplifying other tedious tasks. With the help of automation, you can perform tasks such as:

1.Constructing automation workflows that can successfully configure and manage instances present within the AWS resources.

2.Customizing workflows that are maintained by web services.

3.Implementing the pre-defined workflows that have been provided by AWS.

4.Automated notifications regarding the tasks and workflows by implementing the Amazon CloudWatch Events.

5.Surveilling the process and execution of Automation scripts, either by implementing Amazon EC2 or the AWS System Manager console.

 

Real World Examples of CLI Automation

There is, literally, no limit to the automation tasks that you can perform by the means of CLI Automation. A few such real-world examples are given below:

1.Common IT Tasks: 

As aforementioned, automation can enable you to eliminate numerous tedious repetitive tasks. One such example is the changing of states of instances and managing instance states, both of which can be easily automated. An example of this is using the AWS-StopEC2InstanceWithApproval document. The document allows you to request the approval of singular or multiple Identity and Access Management users and prohibit the further execution of the instance. On receiving the action, the automation script can halt the instance from executing.

2.Performing disruptive tasks in bulk: 

By enabling certain features within the Management Console, you can easily write scripts provisioning you with the control over large groups of instances. These instances can be influenced by EC2 tags and velocity controls. By the means of these tools, you can roll out changes according to the limits defined by you.

The real world example of implementing this lies within the AWS-RestartEC2InstanceWithApproval document. The document enables you to target AWS Resource Groups accommodating multiple instances. Apart from this, you could also implement a configuration allowing the Automation workflows to use the velocity controls.

3.Simplification of Complex Projects

By implementing the correct automation scripts, you could devise one-click automation that simplifies the complex tasks. Amazon Machines Images are the perfect examples of the aforementioned complex projects. Recovering unreachable EC2 is another exemplary example of simplifying complex projects by means of automation scripts.  

The real world example following the simplification of complex projects is the usage of AWS-UpdateLinuxAMI and AWS-UpdateWindowsAMI documents. Using these documents, golden AMIs can be created from a source AMI. The custom scripts can also be executed before or after applying the required updates. Besides this, you could also include a clause that takes care to include or exclude specific packages from being installed.
