If your current setup is becoming harder to scale, more expensive to maintain, or more fragile during traffic spikes, those are clear signals that your cloud architecture needs attention.
Moving to the cloud is not the goal by itself. The goal is better flexibility, stronger load distribution, and faster delivery without disrupting operations. That means migration should be phased and tied to clear priorities.
Start with systems that are either simpler to move or stand to benefit the most from elasticity, then expand based on real results instead of assumptions.
