Blue–green deployment
Alright, let me explain to you what blue-green deployment means in a way that is easy for a 5-year-old to understand.
Imagine you have a favorite toy that you always play with. One day, you see another toy in the store that you also really like. You want to try playing with the new toy without giving up your old favorite right away.
Blue-green deployment is kind of like that. It's a way of updating or changing something without causing any disruptions or problems.
Let's say you have a website that lots of people like to visit. Normally, if you want to make changes to the website, you would have to temporarily shut it down so that you can make the changes and then turn it back on. But this can be a big problem if people are trying to visit the website while it's down.
So, instead of shutting down the website completely, you can create a new copy of the website that you will experiment with, just like your new toy. This new copy is called the "green" version. The old website that everyone is used to is called the "blue" version.
Now, here comes the clever part. You can make all the changes you want on the green version of the website without affecting the blue version. You can test the new features or fixes to make sure everything works properly. It's like playing with your new toy without giving up your old favorite.
Once you are sure that the green version is working perfectly, you can switch the blue and green versions. This means that the green version becomes the new website that everyone sees, and the blue version becomes the new test version. Now, people can visit the website without any disruptions because the switch happens very quickly.
This way, you don't have to worry about the website being down or not working properly while you make changes. You can ensure that everything is working smoothly before making it live for everyone to see. It's kind of like getting to play with your new toy and making sure it's awesome before showing it to all your friends.
And that's blue-green deployment! It's a smart way to update or change something without causing any interruptions or issues.
