Day-7 | AWS Project Used In Production | Complete Implementation |

www.buymeacoff... Hi Everyone, My Name is Abhishek and my channel is focused on delivering Free content on DevOps and Cloud. Follow my channel for practical learning of DevOps and Cloud. Don't miss the FREE DEVOPS COURSE in Playlists.
This video demonstrates how to create a VPC that you can use for servers in a production environment. To improve resiliency, you deploy the servers in two Availability Zones, by using an Auto Scaling group and an Application Load Balancer. For additional security, you deploy the servers in private subnets. The servers receive requests through the load balancer. The servers can connect to the internet by using a NAT gateway. To improve resiliency, you deploy the NAT gateway in both Availability Zones.

Did you get the answer?

[@vamshikrishnaGodhumala]

On Day 3, we connected to an EC2 instance using a key pair that was on our computer. Today, we need to use a bastion host to access a private instance. For this, we first connect to the bastion host. since the bastion host does not have the key pair required to connect directly to the private instance, we need to copy the key pair to the bastion host and then we can connect to that ec2

Hi Abhishek, The tutorial was good, but it would have been great if you could have shown us how to destroy this infrastructure (the VPC). NAT gateways and elastic IPs are the ones that, if forgotten to delete, will cost money. It would be great if you took the below things into consideration. 1) Let us know if it will cost us before we begin hands-on so that we can destroy it after hands-on only. 2) Additionally, if you can, provide a video on AWS billing so that we can keep track of our invoices.

Hello Abhishek, I'd like to share my recent experience. When I attempted to create a bastion host machine, as you suggested, I selected an existing VPC. However, when I tried to copy the private key, it wasn't working. Upon further investigation, I discovered that sometimes, when selecting an existing VPC, the system automatically selects a private subnet. This led to the error I encountered when attempting to access the bastion host. For beginners like myself, this could be a common issue. Therefore, I believe it's important to emphasize the need to select a public subnet to ensure accessibility.

Abhishek sir thanks for this wonderful video , I tried this practical but at 43:26 , when I am pasting DNS url to the browser, I am getting :503 Service Temporarily Unavailable , please help.

[@harshnegi200]

Ok , so I deleted the Target group and the Load balancer and then again I created it , then it started working for me,In this practical I learned a lot of things , thanks again abhisek sir for such a nice tutorial.

[@AbhishekVeeramalla]

Amazing

[@tejasn8625]

@30.05 minutes i am not able to move ,its showing timeout error,i have tried it many times still the same error please reply fast thankyou

[@Rahul-co1jc]

Since Load balancer can only redirect the traffic to registered instances in target group, how can we handle if in the peak season our auto scaling group creates more instances. Since these are not registered under target group, how can we even use them? Anyone please answer. Thanks a ton.

[@AbhishekVeeramalla]

While creating autoscaling, you can integrate the load balancer.

Anna ❤ I have a small doubt 😮 End of the project while refreshing everytime we are getting content from both the servers once a time right.😮 I proudly said to my team lead that I did a project on cloud network design using ALB. 🎉 But he asked me what are you getting output when one server is down due to some reasons. I said that I am getting 502 gateway error. He said improve on this 😢 😂😂😂😂😂 Waiting for your reply anna 😅 ❤❤❤❤

[@AbhishekVeeramalla]

You will get 200 from both. Looks like a misconfugurarion and some times it also takes time.

[@kothadeepakreddy6555]

​@@AbhishekVeeramalla @AbhishekVeeramalla I followed the exact steps, Frankly I did a lot of mistakes But end of the day I am able to access websites by hitting the load balancer But if one server is down, why this is showing 502 gateway error. I think I have to work on this😊 I will try it again 😊 ❤❤❤❤ Thank you anna for replying

Please Help me . I am not able to run scp command Error: connect to host to port 22 : connection time out Scp: connection closed I am using windows

Scp does not work on windows .. u should either use virtual box and installa vm on your machine or copy the pem file using ftp or other ways

[@pinochioism]

while creating the bastion host when we select the VPC from default to our newly created one, just below that you need to select the Subnet type, its by defualt selecting private subnet, so select the public subnet and launch the instance. it will resolve your issue.@@paragpatil1576

[@PrasannaKumar-e2s]

We can login to private hosts from bastion host with out copying pem file to bastion host. If you copy pem file to bastion host it is security breach as if attacker can access to bastion host since it has public ip and with pem file in bastion he can access to private hosts as well
