Transform your deployments from stressful to seamless with these 5 must-know strategies for DevOps engineers:
1. Big Bang Deployment:
Like a fireworks show, you light it up all at once! It's straightforward, but preparation is key. If anything goes wrong, you'll have to roll back to the previous version like a safety net. No downtime, just a big bang for targeted users.
2. Rolling Deployment:
Here you upgrade one section at a time. It's phased and strategic compared to the Big Bang Deployment. No downtime, but it's not just for the VIPs, everyone gets upgraded eventually.
3. Blue-green Deployment:
Here you have two environments deployed in production. The QA team tests the 'green' environment like a knight in training, if it passes the tests, the load balancer switches users over like a master swordsman. No downtime and no one is left behind!
4. Canary Deployment:
You release the new version to a small group of instances first. The QA team watches closely, if all tests pass, we'll release the new version to more users. No downtime, and you'll make sure the new version is singing before releasing it to the masses.
5. Feature toggle Deployment:
Only a select group of users get to experience the new feature. It can be used in combination with other strategies, we can either launch it to everyone at once or just to a select few. No downtime, and only the chosen ones get to experience it.
