Migrating to the cloud is more than a technical upgrade...it's a strategic transformation. At WEI, we seek the latest insights to help our clients navigate this journey. Recently, I attended the Accelerate Your Google Cloud Migration Journey session at Google Cloud Next 2025, which delivered a wealth of practical advice, strategies, and real-world lessons for organizations considering or actively planning a move to Google Cloud. Here are my highlights and actionable takeaways from the session.

Why Migrate to Google Cloud?

The session opened with a compelling case for cloud migration, emphasizing several core benefits:

  • Scalability & Elasticity: Google Cloud enables organizations to scale resources up or down to meet demand, ensuring optimal performance for end users.
  • Global Reach: Deploying services closer to customers improves user experience. For example, launching new data centers in regions like Sydney helps meet local demand and reduces latency.
  • Cost Efficiency: The pay-as-you-go model and server-less options like Cloud Run allow businesses to optimize spending by paying only for what they use.
  • Flexibility & Advanced Tools: Google Cloud offers a suite of AI and machine learning services, giving teams access to cutting-edge capabilities.
  • Reliability & Disaster Recovery: Built-in redundancy, load balancing, and backup tools ensure high availability and quick recovery from outages.
  • Security & Compliance: Advanced IAM (Identity and Access Management), monitoring, and compliance tools help organizations build secure, compliant environments from the start.

A Common Theme Across Hyperscalers

A significant theme from the session is that the core strategies, benefits, and challenges of migrating to Google Cloud closely mirror those found with AWS, Azure, and other hyperscale cloud providers. While each platform offers unique features and tooling, the foundational migration approaches (like rehosting (lift-and-shift), re-platforming, repurchasing, refactoring, retaining, and retiring) are common across all major providers.

The best practices emphasized for a successful migration (thorough planning, detailed inventory and dependency mapping, robust tagging strategies, and a strong focus on security and compliance) are universal requirements, whether moving to Google Cloud, AWS, or Azure.

Hyperscalers provide migration support tools and services, such as Google Cloud Migration Center, AWS Migration Hub, and Azure Migrate, offering centralized platforms for discovery, assessment, and migration management. Likewise, data transfer appliances and services (like Google Transfer Appliance, AWS Snowball, and Azure Data Box) address large-scale data movement needs for all three providers.

The drivers for migration are consistent themes in cloud adoption, regardless of the chosen provider. The importance of hybrid and multi-cloud strategies is also a common thread. Google Cloud, AWS, and Azure all emphasize interoperability, containerization, and flexible workload placement to meet evolving business needs.

In summary, the Google Cloud migration journey shares a common DNA with migrations to AWS and Azure. The same strategic principles, migration frameworks, and operational best practices apply, making lessons learned and tools developed in one ecosystem highly relevant to others. This universality helps organizations leverage cross-cloud expertise and accelerate their digital transformation, no matter which hyperscaler they choose.

Overcoming Migration Barriers

Migrating complex, customized applications (often spread across multiple data centers) can be daunting. The speaker stressed the importance of:

  • Team Training: Upskill teams on Google Cloud Platform (GCP) before migration to smooth the transition.
  • Inventory & Observability: Use observability tools to create a detailed inventory of applications and dependencies. Understanding what you have is essential before moving anything.

Migration Strategies: The 6 Rs

No two migrations are the same, but most fall into one or more of these strategies:

Strategy

Description

Pros & Cons

Rehost

"Lift and shift" existing workloads as-is

Fast, but often costly and not cloud-optimized

Replatform

Make minimal changes to optimize for cloud

Requires more effort, but gains efficiencies

Repurchase

Move to SaaS or managed services

Fast, but may introduce vendor lock-in

Rearchitect

Redesign applications for cloud-native features

Most effort, but maximizes cloud benefits

Retain

Keep some workloads on-premises, migrate new apps to cloud

Useful for legacy or non-migratable workloads

Retire

Decommission outdated or unnecessary applications

Frees up resources, reduces risk

The speaker’s favorite? Re-architecting for cloud-native, leveraging containers and server-less to maximize flexibility and efficiency.

Best Practices for a Successful Migration

  • Plan Meticulously: “If you fail to plan, you are planning to fail.” A robust migration plan is non-negotiable. Start by integrating observability tools like Datadog with your GCP account, providing visibility into your infrastructure, applications, and user experience.
  • Tag Everything: A consistent tagging strategy (e.g., environment, team, service) is critical for organizing resources, tracking costs, and responding to incidents. If you’re not tagging, you’re doing it wrong.
  • Build Dashboards & Reports: Visual dashboards and automated reports keep stakeholders informed and help teams monitor migration progress and performance in real-time.
  • Establish Communication Channels: Set up channels (e.g., Slack) for incident response and ensure alerts are routed to the right teams using tags.
  • Strengthen Security from Day One: Enable security tools and posture management early. Use IAM for fine-grained access control and continuously monitor for compliance, especially if you operate in regulated industries.
  • Leverage Synthetic Testing & SLOs: Synthetic tests simulate user interactions, ensuring applications perform as expected post-migration. Define service level objectives (SLOs) before migrating to benchmark and improve user experience.

Final Thoughts

Every cloud migration is unique. The session reinforced that understanding your current environment, planning thoroughly, and leveraging the right tools and strategies are essential for success. At WEI, we’re committed to helping you accelerate your Google Cloud migration to minimize risk, controlling costs, and unlocking the full potential of cloud-native technologies.
