Question

What challenges have you faced managing multi-cloud orchestration, and how did you address them?

This is a way of probing the issues that arise in managing workloads across multiple cloud providers and the solutions or strategies devised to overcome them. Answers could range from cross-cloud networking and data consistency issues to latency or automation challenges and tools for streamlining multi-cloud operations.

Answer 1

Challenges : Multi-cloud environments present challenges in interoperability, security, and maintaining consistent configurations across platforms. Monitoring is complex due to significant differences in service offerings, APIs, and network structures between providers like AWS, Azure, and GCP. Achieving uniform high security across these clouds is a daunting task.

Solutions :  Address these challenges by standardizing configurations using Infrastructure as Code (IaC) tools like Terraform or Pulumi. IaC abstracts cloud resources into code, simplifying consistency and enabling automated provisioning. Service meshes, such as Istio or Linkerd, provide consistent networking and manage service-to-service communication across clouds. Security and compliance are maintained by restricting access to authorized personnel through tools like HashiCorp Vault and AWS IAM policies. For centralized logging and monitoring, tools like Prometheus, Datadog, or Splunk offer clear visibility into multi-cloud deployments. Interoperability is ensured by conducting regular testing between environments and standardizing APIs and SLAs across cloud services.
