AWS Course Online Today, many people want their apps to work all the time. They do not want any break. If your app stops for even a short time, users can be unhappy. That is why zero downtime is very important. One good way to do this is by using Blue Green Deployments on AWS ECS.
If you want to learn how to do this, you can start by taking an AWS Course Online. It will teach you the tools and steps you need to know.
What is Zero Downtime?
Zero downtime means your app never stops. It keeps working while you update it. This is good for users and for business. No one wants a broken app.
What is Blue Green Deployment?
Blue Green Deployment is a way to update your app safely. It has two parts.
- Blue is your current app.
- Green is your new app.
You set up both at the same time. Then you move users from blue to green. If something breaks, you move them back to blue. This keeps the app running without any stop.
Why Use AWS ECS?
AWS ECS is a tool to run your app in containers. Containers are small parts that hold your app. They make it easy to update and move apps.
AWS ECS works well with Blue Green Deployment. It helps you make changes without stopping the app.
How Blue Green Works on ECS?
Here is how it works:
| Step | Action |
| 1 | Build the new app version (green) |
| 2 | Deploy it to ECS but do not send users yet |
| 3 | Test the new app |
| 4 | Move users from blue to green |
| 5 | If all is good, delete blue |
| 6 | If there is a problem, go back to blue |
This is simple and safe. It helps developers and businesses.
