Deploy a 3 Tier Architecture On AWS - End to End Project Demo
🔥 The second week's challenge was creating a robust three-tier architecture in the cloud of your choice: AWS, Azure, or GCP. Our goal? Build a solution that's highly available, fault-tolerant, scalable, and secure! 💪🔒
💡 I've published this video where I walk you through implementing this challenge to deploy a 3-tier architecture on AWS, considering all the requirements.
In this project, we utilize a public-facing Application Load Balancer, directing client traffic to our web-tier EC2 instances within autoscaling groups. The web tier, powered by Nginx web servers, serves a stunning React.js website while smoothly redirecting API calls to the internal-facing load balancer in the application tier. 🌐📡
Behind the scenes, the application tier, built with Node.js, skillfully manipulates data stored in an Aurora MySQL multi-AZ database. The result? Seamless communication between layers, ensuring uninterrupted operations. Load balancing, health checks, and autoscaling groups work harmoniously at every level, maintaining top-notch availability. 💻🔁
Application Stack: React.js, Node.js, AuroraMySQL
📌By the end of this video, you will learn the following:
- How to create a highly available and fault-tolerant 3 tier architecture on AWS
- How to deploy a web application to a 3-tier architecture on AWS

Hi Piyush,
Thanks a lot for sharing your knowledge with us and making us understand the concept with clear explanation. I really appreciate the work you are doing👌
You are most welcome Asif! I am glad and appreciate your feedback.
@@TechTutorialswithPiyush Please try to create this 3 tier architecture using Terraform modules. It will be a great to learn from you :)
I created the project 3 using terraform which is a 2-tier using terraform, almost the same concept. Please try it out and let me know
@@TechTutorialswithPiyush Ok sure
Hello again! In part 4, when configuring the internal alb, you define port 4000 as the nodejs application port. In my case, I have 9 nodejs applications running on different ports. I thought about configuring Nginx to access port 80 and then configuring the default file and configuring the proxy pass for each application, since AWS does not allow more than 4 target groups. What would security be like in this case? Or do you suggest a different strategy?
Indeed you explained very well❤.
Thank you so much ❤️
Great video !
Thank you so much!
You are always a saviour for me. You helped me a lot in last 2 months.
Always the Best. Thank you Piyush Sir.
Thank you for the great words but it's all your hard work an dedication. Keep up the good work buddy.
Loved the description!...Please make a terraform code video for this as well
Thank you buddy for the feedback! For terraform, you can visit the next video in this series 🙂

Thank you so much 😊
Nice explanation ❤ can you make a video for 3 tier architecture in Azure . It'll be helpful for many students
Thanks for the wonderful feedback! Let me put this item in my to do list
Hello, I watch from Brazil. Congratulations on the excellent video, very educational. I didn't quite understand the connections between the subnets, the route tables and the nats for the private subnets. When you configured the public route table, you included both availability zones, AZ1 and AZ2, but when you configured the application's private route table, you included only the AZ1 zone and did not configure the private route table for the database. Could you explain better please?
Thank you for the amazing feedback 🧡 To understand these networking concept, I would highly recommend to go through the below video and feel free to reach out if you have any further questions

@@hitsistemas365 Good luck Buddy 😊
@Piyush How did your 1st instance in private subnet connected to Nat-GTW got connected to internet? My full VPC setup is correct and security group also, I cannot connect instance to session manager and also not pinging
Please join our discord and share all the details. Your security groups, route tables etc
Hi sir,
could you please tell ,why you have attached only private-subnet-AZ1 to private route table not private-subnet-AZ2 ??
and one more question
why you have not registered EC2 instance in target group ??
Hello Sankalp, It should be done for the Subnets in both the AZs, I might have showed only one. Can you provide me the timestamp where you have this doubt? I will check and let you know.
Hi Piyush! I'm having issues while trying to connect to my EC2 instance through the seession manager. I get an error sign with the following message:
"We weren't able to connect to your instance. Common reasons for this include: ..."
I have assigned the IAM role with the two permissons (the AmazonSSMManagedInstanceCore and the AmazonS3ReadOnlyAccess). What can be wrong? Thanks and amazing content!
Hello, Can you please verify the route table attached to the subnets and ensure that it has route to the internet through the NAT gateway
hi , did you get connected with the instance ?
Hi , did you find any solution ? I am stuck on same issue cannot connect instance
Faced same issue. In my case, I had mistakenly attached private subnet to NAT gateway instead of public web subnet
im having this same exact issue
Bhai mujhe yahi chahiye tha ❤ you bhai
Happy to help mere bhai ❤️
Can you please make a video on 3 tier application in DevOps as a project which includes front end , backend and database
Sorry buddy I didn't understand your question. This video was about a 3 tier implementation which includes front end backed and database, Did you mean anything else?
thank you sir, i did this project and at the final I a can connect with my browser to the page but I can't add the new elements in the table, i collapse the table fields like you do it at 1:09:50 but nothing is displayed in the table,
have you any idea?
Hello, Can you please join our discord community and share the detailed steps you have followed and where you are stuck at the moment. There is a dedicated help channel for 10weeksofcloudops, you can post your query there. Link to our discord channel will be available on our community website thecloudopscommunity.org
Question how come I can view the finished app through the dns of the load balancer but not the ip address of the web instance?
I believe you have opened the inbound port on your web instance to be only able to accessed via loadbalancer and not to the outside world. LB --> Web instance on port 443/80 and not access on port 443/80 on web instance from 0.0.0.0
in the intial video it was writtern 1 prjct per week but there are no posts in this playlist since last month is this series discontinued or is it like in channel members only ..? i am new here so sryy
but idk
Hello Buddy, Glad to know that people are following the videos and waiting for the next ones. Yes, that was correct, As part of our Discord community , we started with 1 project per week but as the complexity is getting increased in every challenge, we are extending the challenges for 2-3 weeks to give enough time for the participants to complete it. Currently we are on week 5, I will be recording week 3-4 videos next week and week 5 video after that. Stay tuned for the updates and feel free to join our community to get the real-time assistance from other community members. Link is in the description.
Hi Piyush. SQL community versions aren't available on sql website anymore. Do you have updated commands which you shared in description if we can use. Thanks

Good and informative video sir. Could you please do the same in azure sir?
I would try my best
u are wonderful
Thank you my friend, I'm glad that you found it helpful 😊
Hello Piyush. This series was wonderful. Weldone. I have a question.. Why don't you also use Terraform IaC to provision the infrastructure rather than doing everything on the console. I believe that is the industry standard. Everyone of us will learn from that as well. Do please let me know your thought about that. Once again thank you for this masterpiece series
Thank you for the amazing feedback and I agree with you about Terraform. I wanted everyone to get their hands dirty on AWS console before actually trying it with Terraform. If you see the next video in this series, it is using Terraform custom modules to provision a 2-tier architecture. I hope that answered your question
@@TechTutorialswithPiyush Thank you Piyush for sharing your amazing skillet with us. The 2-tier IaC was wonderful. If you can, you can also do the 3-tier IaC at your earliest convenience. Thank you
@@MrRuufman Its mostly the same with three tier as well. Maybe I will do that after I'm done with both the ongoing series
Hi Bro,I had watching in your videos,it was explained as well,thank you sharing your knowledge.It' small request could you please share me realtime interview questions and another project aws and devops.Thanks Durairaj
Hello Durairaj, Thank you for the feedback! I will be sharing the real-time projects and implementation as part of #10weeksOfCloudOps challenge. This was project 2, we have 8 more projects in the pipeline, you can also join our discord server to get the weekly updates. Link is in the description.

Thank you sir 😊
Hello, I am on a vacation for the next few days, we will record the video once I am back. You will see that soon.
@@TechTutorialswithPiyush will wait for the video.
Hi Sir,
I have a doubt. Whenever i commit any changes in my application code ( frontend and backend ). How Should i update that code in this 3 tier application?
Hello Naveen, I would suggest implementing a CICD pipeline to make any changes. For now, you can make your changes locally and upload the folder to a S3 bucket and then download that on the server/
i face this error trying to connect to my session manager "cannot connect to your instance" {session manager} please what do i have to do to resolve this error?
Hello Jeff, It will be hard to help you in the comment section over here. Can you join our discord community and share the steps you have performed and issue you are facing in the help channel? someone will help you
hi sir! i have followed through your video and made the same process but when i am giving the command "pm2 list" its giving the status as "errored". what may be the cause sir?
Hello Nitin, Can you check a few things
- if your db config has correct details??
- If your db config is inside the app_tier folder?
- can you run pm2 logs and see if it shows any error?
If you are still facing the issue , join our discord community , link on our website www.thecloudcommunity.org and share your issue in help-10weeksofcloudops channel, someone will help you
What if i want to use the one public facing load balancer and get trafic from web server to app server ??? Is there any way..?
But this is what we are doing, isn't it? please correct me if I am wrong in undestanding the question
How did you overcome the error - need javascript to run the app ( in the web server instance )
I did not face this error, what steps have you performed till now and in which step you are getting this error? please open a new issue in 10weekofcloudops channel in our discord server and someone will help you.
Does it include a bastion host? and if not is it possible to adjust it after the succesfull deploy of that project?^^
This demo doesnt include a bastion host but you can add it later as well. Make sure you configure the security groups properly
i cant understand the commands you implemented in system manager. what should we learn to understand that commands?
I dont think I have used system manager in this video. Do you mean session manager? Those commands are specific to how do we build and deploy a nodejs application. Try to create a sample nodejs application, a simple hello world would work and try to build and deploy it. Also check out pm2 which is a process manager that makes sure your process is running in the background even if you close the terminal. Let me know if you have any questions.
Hi sir, I really liked the video ❤. Could you please specify what pad you are using to write here 52:55
Thank you so much for the feedback. Link is there in the video itself sketch.io
Have you created more videos linked to AWS workshops?
Hello, As of now only this video is related to AWS workshop. I might create more in the near future
hello sir, the entire video is really helpful but I've one doubt, is it mandatory to use s3 ?and why u use it
Thank you for your feedback. I did not use S3 in this demo as it was not required. S3 is used to store static files such as images, videos etc so that it can be rendered on the web application. For example, When you have a website with a product catalogue such as amazon.com, each product has a lot of metadata such as thumbnails, images, images people post in reviews and so on, those images need to be stored somewhere so that it can be loaded on the website with minimal lag/latency, in that case we use S3 and cloudfront. I hope this answered your question, if you need more details, I would suggest checking out Project 1 of this series which is about S3 and cloudfront.

I am a backend tech lead. With day to day activies in design , development , testing and deployment in amazon cloud . I know and do deployment in amazon cloud hands on . Knows ubuntu linux and java backend . But dont now aws . How thats different 🤔🤔
Hello, Sorry I didnot quite understand your question. You mean you work on the development side on AWS and do the deloyments as well but how's that different from setting up the infra? Is that your question then, I can try answering it.
Setting up your infrastructure is usually happens using IaaC tools such as Cloud Formation, Terraform, Pulumi etc and this is mainly done by a seperate team, this could be Infra team or DevOps team or a Cloud team. The infra needs to be setup so that other teams including developments start using it, there is also a need of regular maintenance, creating CICD pipelines, and other operational tasks carried out by these teams. Let me know if this makes sense or if I misunderstood your question.
Regards,
Piyush

please let me know, is all the services used in this project are free? If i used this services in the AWS free tier, does it cost me some money?
You can use t2.micro for frontend and backend servers that are covered under free trial , there will be a small cost of ELB. RDS also has some cost of using it, if you dont want to spend that, you can setup your RDS cluster (Master and read-replica) on seperate EC2 servers and use that.
Hello piyush, Thank you for the video. Can you please tell me how much this project will cost?
I believe most of the services will be covered in the free tier. but you can have a look to the aws site and check out what all services are covered under that and you can also generate a pricing estimate using the aws pricing calculator.

Hello Buddy, I have used DNS in project 1 of this series, feel free to check it out.
Hi sir, Can we deploye without nginx and how?
If you are using a high available and fault tolerant architecture meaning you have multiple copies of the same server running, you need some sort of load balancing to load balance the traffic to downstream. There are other alternatives of nginx such as apache that you can use.
Can we add this project to our resume
If you have completed the project end to end then yes, you can definitely add this in your resume also, make sure to include your GitHub/blog hyperlink in the resume for validation.

Any cost involved in this project steps?
You can use t2.micro for frontend and backend servers covered under a free trial; there will be a small cost for ELB. RDS also has some costs of using it. If you don't want to spend that, you can set up your RDS cluster (Master and read-replica) on separate EC2 servers and use that. Also, I would recommend checking out the price estimates using AWS Pricing calculator
Thanks

Please help me what details we need to enter in this section
Thank you in advance
db host is the rds write instance endpoint, db user and password that you have created and db database the database you created using mysql session
Please write the format if possible@@TechTutorialswithPiyush

Hello ,
You can use t2.micro for frontend and backend servers that are covered under free trial , there will be a small cost of ELB. RDS also has some cost of using it, if you dont want to spend that, you can setup your RDS cluster (Master and read-replica) on seperate EC2 servers and use that.
You can also check out AWS pricing calculator and make sure to destroy the resources after the use.
itna sab kerne ka kitna cost ayega
If you create the resource and destroy it as soon as you are done only a few resources will be charged such as ELB, NAT and RDS. Cost you can check from AWS pricing calculator, it will be a good learning exercise for you.
@@TechTutorialswithPiyush yeah ok then i aware of NAT price but i am just worried about RDS .
Not working properly, I followed the exact tutorial
There could be some setup issues. Can you join our discord community and share the details, where exactly are you stuck, error messages, pm2 logs etc. we will help you.

@@nandkishormetangeHey bro Did got, your issue is resolved?
Sir RDS is costing 240 doller can we use any free tier database??
Hello Ankit, it shouldnt cost you that, you could have used the dev RDS instance with one replica. However, if you want, you can install mysql on EC2 server as master and read replica and implement the data replication across the two servers, that's even better in terms of learning. Good luck
Hi! Getting an error "fatal error: An error occurred (AccessDenied) when calling the ListObjectsV2 operation: Access Denied" when trying to give this command: cd ~/

Hello Saumya, Looks like your IAM user doesnt have access to download the objects from this bucket. Make sure your S3 role attached to the EC2 instance so that it can authenticate on your behalf.
@@TechTutorialswithPiyush yes it worked fine after your suggestion. Thank you!

Can I use S3 to host files as a web tier?
S3 can be used only to static pages, you cannot use that for 3 tier app with backend and db
