I have extensive experience with AWS, having managed large-scale data systems for over five years. My role involved setting up and optimizing data pipelines, ensuring high availability, and implementing disaster recovery solutions. I am also proficient with Azure, where I led a team in migrating on-premise databases to the cloud, resulting in a 30% reduction in operational costs. My experience with Google Cloud includes deploying scalable data processing solutions using BigQuery and Dataflow.

Ensuring data security and compliance involves a multi-layered approach. I implement encryption both at rest and in transit, use role-based access controls (RBAC), and regularly audit permissions. I also stay updated with industry standards and regulations, such as GDPR and HIPAA, and ensure that our cloud configurations adhere to these standards. Additionally, I conduct regular security assessments and vulnerability scans to identify and mitigate potential risks.

I have significant experience with automation tools like Terraform and Ansible for cloud data management. I use Terraform to automate the provisioning of cloud resources, ensuring consistency and reducing manual errors. Ansible is my go-to tool for automating configuration management and orchestration tasks. I have also integrated these tools with CI/CD pipelines to automate testing and deployment processes, leading to faster and more reliable updates.

Data migration involves careful planning and execution. I start by assessing the current on-premise environment, identifying dependencies, and creating a detailed migration plan. I then use tools like AWS DMS or Azure Data Migration Service to transfer data with minimal downtime. Post-migration, I validate data integrity and performance, and ensure that all applications are functioning correctly in the new cloud environment. Continuous monitoring and optimization are key to a successful migration.

Optimizing cloud data storage costs involves several strategies. I regularly review storage usage and identify underutilized or redundant data, archiving or deleting it where appropriate. I also leverage tiered storage solutions, such as Amazon S3 Glacier or Azure Cool Blob Storage, for infrequently accessed data to reduce costs. Additionally, I implement lifecycle policies to automatically transition data between storage classes. Finally, I monitor and analyze cost trends to identify areas for further optimization.
