I’ve been running my applications and services on AWS for years. It’s powerful and feature-rich, but over time I realized it wasn’t always the best fit for my needs. Recently, I decided to migrate to a new cloud platform—and the results have been surprisingly positive.
In this post, I’ll share why I made the switch, the challenges I faced during migration, and the benefits I’ve seen. Hopefully, it helps other developers thinking about cloud choices.
1. Why I Considered Migrating
While AWS is extremely capable, I ran into a few issues:
Unpredictable costs: Pay-as-you-go is convenient short-term, but as projects grow, the complexity of resource usage made bills hard to forecast.
Too many services: AWS offers hundreds of services, many of which felt overkill for small to medium projects.
**Steep learning curve: **Managing EC2, VPCs, IAM, CloudFormation, and other components required a lot of time to understand and configure.
Inconsistent performance: Latency and I/O performance varied across regions, which was challenging for low-latency apps.
I wanted a platform that was simple, cost-predictable, performant, and easy to manage.
2. Challenges During Migration
Switching cloud providers is never trivial. Some of the main challenges included:
**Service compatibility: **Some AWS-specific services didn’t have direct equivalents, so I had to rewrite parts of the code or swap services.
Data migration: Moving large databases and storage had to be zero-loss and highly available.
CI/CD adjustments: Existing automation, monitoring, and alerting setups needed to be adapted to the new platform.
How I addressed these:
- Migrated low-risk services first, then gradually moved core systems.
- Used the new platform’s migration tools to ensure data integrity.
- Took the opportunity to refactor parts of the architecture to reduce complexity.
3. Benefits After Migrating
After a few months on the new cloud platform, I noticed:
Transparent, predictable costs: Simple pricing and a mix of on-demand and reserved resources made billing almost fully predictable.
Improved development efficiency: Streamlined console and APIs made deployments and management faster.
Stable performance: High-performance networking and I/O improved app responsiveness.
Lower learning curve: Fewer services meant my team could focus on business logic instead of cloud management.
Key Takeaways
AWS is a mature and powerful platform, but that doesn’t mean it’s the best choice for everyone. When choosing a cloud platform, consider more than features:
Are costs predictable?
Is management simple?
Is performance stable?
Does the learning curve fit your team size?
Migrating gave me better control over costs and development efficiency, and reminded me that cloud platform choice should always align with your team’s needs, not just industry hype.
Have you ever considered moving off AWS or another major cloud platform? Or are you evaluating alternatives? I’d love to hear your experiences, challenges, or lessons learned in the comments.
