1. head
2. tail
3. yes we can change ssh port
4. From 0 to 65535 total ports
5. Ports allow the operating system to distinguish between different services running on the same IP address.
6. to count number of hops we use traceroute command
7. SSL enables an encrypted connection between the web server and the client's web browser.
8. Docker instructions are not case sensitive and tried to use single RUN instruction by using &&
9. Scratch is a special, minimal image that serves as the starting point for building Docker images. It represents an empty or base image with nothing in it.
10. Alpine is a lightweight Linux distribution that is commonly used as a base image for Docker containers. It is known for its small size, simplicity, and security focus.
11. Rate Limiting Services are nginx, traefik, istio and traffic observability using prometheus

[@ahmedsaif4541]

Couldwatch desinged just to collect metrics in aws services and resources , while promethus + Ghrafana provide more observablity for micro services in terms of observability

[@pournima_543]

Please list all questions in PDF format

[@jigssheth91]

Can you please make that and share with us, if possible, answers also, thanks

[@user-rp6ye5yd9i]

😅

[@TechWithPrerit]

From the next episode, I will add 1-2 mins video of me explaining answers in the very end...

[@ahmedsaif4541]

for rate limiting + ip blocks in terms of micro services , i think aws WAF is enough, if the others layers like 3 , 4 needs to be included alongside layer 7 , i will go with shield advanced service , right ?

[@welcomeblessingssayi10]

Thank you so much Prerit, so insightful

[@TechWithPrerit]

[@Wasiyat]

[@yashwanthbachupally1246]

what is dockershim component... what it will do and why they are removing it please explain

[@abhaymaurya944]

As far as I know, dockershim is a layer that is used for run docker container in Kubernetes, because it is not following CNI principles, thats why the layer has been created to used docker containers, but docker is heavyweight thats why we are using containerd and cri-o as a container runtime instead of docker. If you want still want to use then you can search mirantis dockershim.

[@user-hj7xf5qr7l]

Is AWS lake formation right solution for the data warehouse question asked?

[@user-hj7xf5qr7l]

Or may be Redshift?

[@TechWithPrerit]

Sure I will

[@yashwanthbachupally1246]

Difference between containerd and dockershim component... explain little simple way

[@abhaymaurya944]

containerd is a container runtime which is used to run containers while exactky containerd (high level container runtime) calls runc (low level container runtime) to run the containers. Dockershim is a layer which is used to run docker containers.
