Project 3 - Deploy A 2-tier Application On AWS Using Terraform | Custom Modules in Terraform

Deploy A 2-tier Application On AWS Using Terraform - Custom Modules in Terraform.
Welcome to the 3rd video in the series #10weeksofcloudops. In this challenge, we need to deploy a 2-tier architecture on AWS using Terraform custom modules which should be highly available and scalable. To achieve that, we will use the following list of services of AWS.
📃 list of services
Amazon Certificate Manager (SSL)
Amazon Route 53 (DNS service)
Amazon CloudFront(CND)
Amazon EC2 (Server)
Amazon Auto Scaling group (Scale on demand)
Amazon VPC (Virtual private cloud: Private Network)
Amazon RDS (Relational database services: Database)
Amazon DynamoDB (State-locking for tfstate file)
Amazon S3 (storing backend and achieving versioning)
Amazon CloudWatch (Alarm when CPU utilization increases or decreases)
📌By the end of this video, you will learn -:
- How does Terraform work
- What is the remote backend in Terraform
- What are custom modules in Terraform, and how do create them
- What are the variables in Terraform
- Input Variables v/s output variables
- State file locking in Terraform
- Terraform best practices
- Provision a 2-tier architecture on AWS using Terraform custom modules

Thank you! This project-based playlist is truly beneficial and rare to find, especially for free. I really appreciate your service to the AWS and DevOps community. Please complete this playlist as early as possible. This playlist deserves 100k subscribers; I think it hasn't reached many people.

[@TechTutorialswithPiyush]

Thank you so much Nasir for your kind words! I truly appreciate your feedback :) Yes, I will be completing it soon. Stay tuned for the next project coming up soon.

[@awssoorinje747]

Sir,Thanks for the project-based videos on AWS cloud! They provide a real-time feel, and I'm eagerly waiting for the next project. Please upload it as soon as possible.

[@TechTutorialswithPiyush]

Thank you for your feedback! I'm glad to hear my videos are helpful. The next project will be uploaded this week, so stay tuned!

Sir, please include diagram explanations like in Project 1 before starting hands-on. It helps grasp the concepts easily and quickly. Include this in all your upcoming projects. Thank you

[@TechTutorialswithPiyush]

I added a diagram explanation to this video, but I will spend more time explaining it in the future. Thank you for your feedback, I appreciate it.

[@nightfly3358]

Good Video man , thanks for keeping it short and precise. can you provide some info on how Ankit created that diagram ?

[@TechTutorialswithPiyush]

Thank you for the feedback! He used Microsoft Powerpoint to create the animated diagrams.

[@nightfly3358]

@@TechTutorialswithPiyush I had a cloud challenge to perform at work, and I must say I copied most of the stuff you taught , it was really helpful. Have you don’t anything with compliance software like Chekhov ?

[@ashutoshpangavhane7024]

where did you declare keys for your back end to connect with the provider,

[@TechTutorialswithPiyush]

I didn't have to, the user I used to authenticate with Azure had a storage account object viewer role so access keys not required

[@ibmuser13]

Hello Piyush bhai, thank you very much for this video. Just a question - can we not use Terraform public modules for vpc, ec2, rds etc for this 2-tier architecture? Why did we have to create custom modules? Thanks again for your selfless service!

[@TechTutorialswithPiyush]

Thank you for the great feedback buddy! To answer your question: We can definitely use public module however, it is not a production best practice. Public module are maintained by the owner or a separate organization and any changes in that could directly impact your production environment hence, organization like to retain total control of the module. I hope this answered your question.

[@Jalal921]

Great Piyush, Can you please creat a project in Azure as well

[@TechTutorialswithPiyush]

Thank you brother for the feedback, I already have a similar project in Azure, here's the link kzbin.info/www/bejne/f16wk6Gcg8icoc0

Great, Thanks a lot. Looking forwad for many such projects

[@MdAshraf007]

Hi sir, do we normally keep multiple Nat gateways? Especially for cases like in EKS cluster?

[@MdAshraf007]

I created my cluster with eksctl and it created only one NAT. Is there an issue with this?

[@TechTutorialswithPiyush]

NAT Gateways doesnt span Availability Zones, if you deploy your resourced in multiple AZs , then you need to setup NAT for each Zone seperately. Hope this clears your confusion.

[@zamo2049]

Hello, thanks for this projects. I think the solution in github is missing the Jumpbox module for the connection

[@TechTutorialswithPiyush]

Hello, Thanks for pointing out, yes the jumbox module is missing in the Github and the video

[@bezanpithawalla234]

Hello, Whenever I run “tf init”, I keep getting an error message saying “Failed to read module directory” and “Module directory does not exist or cannot be read”. Any idea on how to fix this? Thanks!

[@TechTutorialswithPiyush]

You need to run it from the directory where your root module exists. It looks for .tf files in the directory

[@bezanpithawalla234]

@@TechTutorialswithPiyush So, are you saying I should save my .tf module files in the root folder and then try running it again?

sir in terraform what is taint? can u please teach about this

Hello, We taint the resources created by Terraform to mark it is a broken and instruct terraform that it should be recreated/replaced during the next terraform apply but now the command has been deprecated and replaced by -replace

[@madhulikapaluri8020]

is it free tier?

[@TechTutorialswithPiyush]

Not every service will be covered as part of free tier. e.g Load balancers, NAT Gateways, RDS etc are not covered in free tier.

[@user-rs7un1hp6v]

can I do that with aws free account ?

[@TechTutorialswithPiyush]

I believe most of the services can we covered within free tier. make sure you understand what is covered and what is not. For example, EC2 Micro instances are covered and not all EC2 instances. You will find the details in the documentation. You can go to below page and checkout the details for each services used in the demo: aws.amazon.com/free/?all-free-tier.sort-by=item.additionalFields.SortRank&all-free-tier.sort-order=asc&awsf.Free%20Tier%20Types=*all&awsf.Free%20Tier%20Categories=*all
