What is Blue Green Deployment?

But blue one will be ideal once green went live, will usually be removed or just keep it for next release.

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?

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?

Amazing video! Thank you!

It was indeed a great and quite informative video Sir..learnt something new today!!
Please keep more such content coming 🙌

Does it increases cost or is it a copy of whole system.

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?

more details will be greatly appreciated.

thanks for the video

bro you're outstanding

What would happen in case i want to rollback my service to some previous version because the current service failed.

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?

Thank you very much Sir, and yes we needed such videos to keep ourselves updated.

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?

I love the way you represent ❤

Well explained, so clear! Appreciate it!

Nice explanation sir. Really helpful. Thanks a lot.

Yes @Telusko sir..we need a lot such more informative vedios

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

What is the difference with canary?

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.

Advance congratulations for 2M sir 🎉🎉🎉🎈🥳❤

Very interesting information, can you please create a separate playlist for Infra related videos

Is Using the blue green concept feasible in terms of cost? The cost would double, wouldn't it?

Informative Video Sir

How it is different from canary deployments ?

Sir We need to a phyton sreise for the new genaretion hope u will start it very near

We need more videos like this

@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

Thanks Sir for making a video on this topic.
Could you please also cover topics related to deployment or CiCD , devops

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!

Thanks , very useful

Advance congratulations naveen sir for 2M subscribers🎊

So, It's something similar to production and disaster recovery server.
Informative 👍

Awesome explanation. Would love to see videos on deployment on Hydra which is cloud based platform

Great full information and please make the same kind of videos which are used in IT projects

Very much practical

We use the same deployment in our product

Great content Naveen. We would love to have videos on more such technical jargons.

Thank you

Wonderful 💯

thank you sir
