Common Pitfalls to Avoid
- ⚠️Underestimating the complexity of IP address management and avoiding IP conflicts across environments.
- ⚠️Treating cloud networking as an afterthought, leading to security vulnerabilities and performance issues.
- ⚠️Lack of unified visibility into network traffic and performance across on-premises and cloud.
- ⚠️Failing to implement consistent security policies and controls, creating gaps in the security posture.
- ⚠️Relying on manual configuration and management, which is unsustainable and prone to errors in a hybrid environment.
Potential Follow-up Questions
- ❓What about hybrid IAM integration?
- ❓How to monitor latency?
