Thanks a lot for your great information sir Everyday I do watch your videos without miss sir & one more thing I want to share is.. I'm from mechanical domain but now working as a Java developer because I followed all ur UA-cam videos sir 🙏🙏🙏🙏🙏
It's a great idea, just a major cons. because of which not every company is using this and we still see most of the companies has a scheduled downtome is, the cost of handling one more production level infrastructure.
What if we have database change in migration plan from version 2.5 to version 3.0, like alter table to add new column, or add new table with one-many relationship with existing tables and etc. How to manage the Blue-Green deployment and partial migration to test the v3.0 with zero down time while 2.5 still needs to be accessable?
Thanks for the woderful lecture. Can you please a video on its implementation for a real world application. Like all the jules configurations and how to achieve it?
@Telusko thanks for the video. Question, what if part of the update is to upgrade the database? Schema update, or entirely db version update? In this case, would you suggest such a technique, and if so how is it supposed to happen? Thanks
Well I can guess that we can make a db instance for each deployment, but syncing them together would be not so easy. Moreover not every technic is suitable for every situation.
Hello @Telusko It's a great approach Also i want to share my thoughts on ecs service in AWS Please help me in the comments if i am wrong I think ecs is a good solution for continuous deployment ( without keeping an instance alive all the time and paying cost ) While using ECS, Since we are using docker images to deploy our application so definitely we have all previous versions saved One more benefit : ECS is very smart while deploying applications, it first up the newer application and then after getting a successful deployment it smoothly downgrade the older version which was running. This is good because users will never face downtime even if the newer version has some problem while deploying
Good morning sir, i am so delighted to see your video about the BG DELPOYMENT. please can you make another video in other to explain what really happens behind the scene {back end] during a bluse green deployement?
I think conceptually this all works fine. My questions are around the point of having shared database, doesn't that limit your to have no database schema changes between 2.0 and 3.0? Also if you have database schema changes than how will a shared database work without downtime?
@5:06 you mentioned about the third instance? so where is this third instance? so we create another instance color? I'm asking beause I didn't quite understand, let say we have anothe update to roll-out, let say version 3.5, where do we deploy it? do we use the blue instance?
Hi sir, could you help us the viewers to know about canary deployment vs blue green vs rolling update. And also how the traffic is switched. Thanks you
Please is there anyone who can provide me with a job? I really need help currently. I have learned html css and now learning js. Please anyone who can help me? As i will return some amount of money from my first salary to you but i really need one job. Family conditions not so good they can't pay for bills. It's a request. Please see i am a Mechanical Engineer!
Sir could you help me with the below error. I tried spring mvc by xml configuration followed your video but I am getting javax.servlet.ServletException error initializing servlet class(Dispatcher servlet) root cause is java.lang.NoClassDefFoundError jakarta/servlet/http/HttpServlet.
Thanks a lot for your great information sir Everyday I do watch your videos without miss sir & one more thing I want to share is.. I'm from mechanical domain but now working as a Java developer because I followed all ur UA-cam videos sir 🙏🙏🙏🙏🙏
Advance congratulations naveen sir for 2M subscribers🎊
Thank you very much Sir, and yes we needed such videos to keep ourselves updated.
Нормальный видосик, доступно объясняет !))👍
Yes @Telusko sir..we need a lot such more informative vedios
Is Using the blue green concept feasible in terms of cost? The cost would double, wouldn't it?
Wonderful 💯
Thank you for explaining
It was indeed a great and quite informative video Sir..learnt something new today!!
Please keep more such content coming 🙌
It's a great idea, just a major cons. because of which not every company is using this and we still see most of the companies has a scheduled downtome is, the cost of handling one more production level infrastructure.
I love the way you represent ❤
Advance congratulations for 2M sir 🎉🎉🎉🎈🥳❤
So, It's something similar to production and disaster recovery server.
Informative 👍
Nice explanation sir. Really helpful. Thanks a lot.
Very much practical
We use the same deployment in our product
Great Explanation sir Thank you
Well explained, so clear! Appreciate it!
Great content Naveen. We would love to have videos on more such technical jargons.
Great full information and please make the same kind of videos which are used in IT projects
Thanks for the useful Info sir..
What if we have database change in migration plan from version 2.5 to version 3.0, like alter table to add new column, or add new table with one-many relationship with existing tables and etc. How to manage the Blue-Green deployment and partial migration to test the v3.0 with zero down time while 2.5 still needs to be accessable?
Thanks Sir for making a video on this topic.
Could you please also cover topics related to deployment or CiCD , devops
We need more videos like this
Thank you soo much sir ☺️😁
thank you sir
What would happen in case i want to rollback my service to some previous version because the current service failed.
bro you're outstanding
Very interesting information, can you please create a separate playlist for Infra related videos
Thanks for the woderful lecture. Can you please a video on its implementation for a real world application. Like all the jules configurations and how to achieve it?
Amazing video! Thank you!
What is the difference with canary?
Yes more videos please 👍
Awesome explanation. Would love to see videos on deployment on Hydra which is cloud based platform
Thanks , very useful
@Telusko thanks for the video. Question, what if part of the update is to upgrade the database? Schema update, or entirely db version update?
In this case, would you suggest such a technique, and if so how is it supposed to happen?
Thanks
same question here
Well I can guess that we can make a db instance for each deployment, but syncing them together would be not so easy. Moreover not every technic is suitable for every situation.
Thank you
thank you sir
How it is different from canary deployments ?
Hello @Telusko
It's a great approach
Also i want to share my thoughts on ecs service in AWS
Please help me in the comments if i am wrong
I think ecs is a good solution for continuous deployment ( without keeping an instance alive all the time and paying cost )
While using ECS, Since we are using docker images to deploy our application so definitely we have all previous versions saved
One more benefit : ECS is very smart while deploying applications, it first up the newer application and then after getting a successful deployment it smoothly downgrade the older version which was running.
This is good because users will never face downtime even if the newer version has some problem while deploying
Sir We need to a phyton sreise for the new genaretion hope u will start it very near
more details will be greatly appreciated.
This is such an informative video

What about changes in DB which is shared here? How to ensure ZDD there
What's the difference between blue/green and canary?
Does it increases cost or is it a copy of whole system.
The green instance's database is in read-only mode, so I can't change it. How am I supposed to test my database changes with my apps?
But blue one will be ideal once green went live, will usually be removed or just keep it for next release.
@5:06 you mentioned about the third instance? so where is this third instance? so we create another instance color? I'm asking beause I didn't quite understand, let say we have anothe update to roll-out, let say version 3.5, where do we deploy it? do we use the blue instance?

sir tell a little bit slow , it is hard to gain as a beginner
So much unnecessary talk.. please directly jump to what is blue green
You r wrong he is Explaining every point deataily, This is the best Video of explaining Blue green Deployment
But I think his unnecessary talk helps me
Sir could you help me with the below error. I tried spring mvc by xml configuration followed your video but I am getting javax.servlet.ServletException error initializing servlet class(Dispatcher servlet) root cause is java.lang.NoClassDefFoundError jakarta/servlet/http/HttpServlet.
thanks for the video
