Hi, Abhishek can you please make a video for shell scripting beginner to advanced level,and thanks for the OSI model

Sir how many more videos of this playlist will you upload?

Could you please make a video on DNS and Load balancer.

You are a champion

Very nice explanation. Thankyou for making it free rather than focusing on money. Have you considered making complex projects and explaining it in the way? Like how a project is started and completed in a professional way.

Hi Abhishek, I am a DevOps engineer with 4.5 years of experience. I am very confused and have too many second thoughts on the career switch. I started as a production support engineer and continued for almost 3 years. I was taken as a DevSecOps engineer in my current organization and later as DevOps in a different project. I worked on terraform for 4 months and the project ended. To say as DevOps I do not have practical experience, but I also have basic knowledge of Java and have done testing of APIs and part of regression, and sanity testing during my period as a production support engineer. I am in the dilemma of which field to take either DevOps or Testing. I have completed your DevOps Zero to Hero Playlist. I understand the concepts through your videos. As I am on bench now I am not sure where exactly to spend my time. I do not have any specific cloud knowledge. Could you please guide me if I can choose DevOps or should go into automation testing? I am sorry for the long text but did not know how exactly I could communicate with you alternatively.

In tcp-ip model L7-L6-L5 models are combined. So tcp-ip model is also based on osi model.

Thank You ❤

Bro is it possible for you to make detailed video of DNS and all related concepts which cotains everything.. for the interview point of view? Becoze they ask DNS everywhere in detail for no reason. Thanks

Sir providing class notes what you taught in the session

Hey Sir, Explained in a very awesome way. I saw some linux videos and now i can't find there were 2-3 videos, can you please send the direct link. Also i am sharing the channel name with many of my friends

thankyou sir

At senders end, data is transmitted from L7 to L1. At receiver's end data is transmitted from L1 to L7.

Thanks

Thank you sir

Hi Abhishek,i have one doubt. how the world connected to network ?

Layer 1 to 7. Dns resolution and tcp handshake happens even before request is sent from browser to server. Dns , think of it as simple database that has mapping of hostname to ip address and vice versa. In router . Every ISP maintains a DNS. After DNS resolution, tcp handshake takes place , sync, sync-ack and ack. It's called 3 way handshake. After tcp handshake, data initiation starts and osi models xomes into picture. Layer7, application stage. Http or ftp based request. Layer6 - presentation layer, responsible for data encryption and formatting L5 - session layer, session is created btw you and server so you don't have to authenticate again and again. Session is basically taken care by cookies and cache, you can clear in browser for new session. L5-L7 is taken care by your browser itself. L4- transport layer, in this layer segmentation of data takes place, along with segmentation protocol is also identified such as TCP/UDP. L3 - network layer, which router or hops takes place to route data to destination. In this layer source and destination ip is defined, we call this data as packets. So that routers can understand. L2 - data link layer . Data is converted from packets to frames for switches to understand. Along with ip, mac address is also added. L1, at the end of day all devices are connected to optical cable. Data is transmitted as electrical signals in these optical cables, data is transmitted very fast in optical cable।

Thanks @abhishek its really simple and understandable, is there any notes you have created in github i have check in the link but can't find out could u pls help to get the notes on this networking videos

Abhishek sir i have saw thr linux playlist (bash scripting) and this networking fundamental both part is it enough for devops

Sir could you educate us on aws cloud9 ?

sir when you teach something kindly use black as background ....white is little bit less comfortable ...# black is best

❤❤❤❤❤❤

Hi really need your guidance on this, I am currently doing AWS Devops course but I am more interested in cloud support associate like solving cases, tickets... Since I find it more interesting and has experience working in a hosting support... Do you think AWs DEVOPS course will help me with this goal ? Can you recommend any of your classes to accomplish my goal as a cloud support associate...

Could you create more networking videos please :)

We need a video on SSL certificate and certificate managemnet ?

Hello groovy scripting is good and has future?

Abhishek sir today I saw a video by one Devops engineer based out of Canada that fascinated me a lot. She was an existing devops practioner in the industry and working since 15 years in IT. She achieved 6 aws certifications in 6 months .She told her study routinw for exam.She gave around 2 hours on weekdays and 8 hours on weekends to study for exam.Also she metioned the udemy course of Stephen Marrek she used and some practice papers she gave. I am a student currently learning devops from your channel and side by side aws and dsa too. My exposure to hands on and cloud have not been that much as her. Should I still go for getting certificationa as it can make me stand out of the crowd but there will be a very high risk of money factor as I will be not paying the money by myself but my parents and time. Also with this limited exposure to cloud and devops will it be ok if I try studing for these certifications? Will it get me some practical knowledge or it is better to focus on what I am learning right now? I am really sorry for such a long question but will be very thankful if you could answer this.Thanks for guiding me always.

Hi Bro , Your Course AWS Zero to Hero Playlist Vs AWS Cloud Computing, both are same courses ?

Please create Networking Playlist
