The Challenge
The cloud migration process presents business and technical challenges
The client needed to overcome significant barriers while exiting their data center (DC) and achieving the subsequent cloud migration and transformation objectives. Their US businesses were facing challenges in meeting customer demands to be innovative and competitive while embracing agile ways of working. At the same time, they wanted to reduce the operational and hosting costs. Therefore, they decided to embrace public cloud infrastructure and move their workloads to the cloud.
The Objective
Determining goals to ensure successful and rapid cloud migration
The client aimed to establish processes to bypass the existing challenges and meet their goals efficiently. Key objectives included:
- Selecting a cloud platform that meets all specific workload-related needs
- Building a GCP Landing Zone and Migration Factory to streamline and accelerate the end-to-end migration process
- Implementing robust security measures to secure internet traffic for both production and non-production scenarios
- Creating an isolated environment that supports seamless SAP-based migrations
