Deployment Strategies Guide 🚀

Deployment strategies determine how applications are released to production environments. Here are common approaches:

1. Blue Green Deployment 🟦🟩

• Description: Swap between two identical production environments (Blue and Green).
• Advantages: Zero-downtime updates, easy rollback.
• Use Case: Ideal for applications requiring high availability.

2. Canary Release 🕯️

• Description: Gradually roll out changes to a subset of users.
• Advantages: Minimizes risk, allows real-time feedback.
• Tools: Often paired with traffic splitting (e.g., Kubernetes, NGINX).

3. Rolling Update 🔄

• Description: Replace old instances with new ones incrementally.
• Advantages: Maintains service during updates.
• Considerations: Requires sufficient resources for parallel instances.

4. A/B Testing 🧪

• Description: Test new versions against a portion of traffic.
• Use Case: Validate performance or user experience changes.

5. Rollback ⚫️

• Description: Revert to a previous stable version.
• Triggers: Failures, performance issues, or security concerns.
• Best Practice: Automate rollback processes for faster recovery.
