Moving Cloud Infrastructure Methods
In today's digital landscape, businesses are increasingly turning to cloud solutions to achieve their goals, and Google Cloud offers a comprehensive approach to migrating workloads.
The Power of Containerization
Containerization is a key element in this process, particularly for stand-alone binaries or JAR files. Java and JAR files are especially flexible, as the Java Runtime Environment (JRE) can stay within the container, making them easy to move and manage. This freedom empowers developers to create, test, and deploy applications with ease.
Migration Strategies for Google Cloud
Common strategies for migrating workloads to Google Cloud include:
- Rehosting (Lift-and-Shift): A fast approach that moves applications without modification, allowing businesses to quickly leverage cloud services.
- Replatforming (Lift-and-Reshape): Slight modifications to optimize performance or cost, balancing speed and modernizing benefits.
- Refactoring (Re-architecting): Redesigning applications to fully utilize Google Cloud native services, offering scalability and cost efficiency but requiring more time and investment.
The Migration Process
The migration process generally follows a structured approach:
- Assessment and Inventory: Document workloads, dependencies, and configurations to design the migration plan accurately.
- Planning: Prioritize applications by business value and complexity, establish timelines, risk management, and security measures such as backups, sandbox testing, and rollback strategies.
- Execution: Start with low-risk assets for pilot migration, continuously monitor performance, validate data integrity, and use reliable migration tools like Google Cloud Migrate to track progress.
Enterprise Migration Considerations
For larger organizations, migration planning often involves:
- Designing migration roadmaps considering complex dependencies, governance, and compliance requirements.
- Managing quotas and workload distribution, especially for large workloads running on Google Kubernetes Engine (GKE), using resource hierarchies like projects and folders aligned with organizational boundaries.
- Engaging account managers for support with very large workloads (hundreds of thousands of CPUs or GPUs) to optimize availability and configuration.
- Addressing challenges such as cost management, vendor lock-in, and data security/compliance during migration planning.
Tools for Google Cloud Migration
Google Cloud provides several tools to support enterprises during migration:
- Google Cloud Migrate: Automated tools supporting migration planning and execution.
- Google Kubernetes Engine (GKE): For containerized workloads, with best practices for large workload distribution.
- Third-party solutions like NetApp Cloud Volumes ONTAP help with high-performance data migration, protection, and scalable storage management.
Cloud Run and Anthos
Cloud Run combines the benefits of containers and serverless, offering automatic scaling and pay-for-usage, while Anthos can be used to manage on-premise and hybrid-cloud or multi-cloud environments.
Containerization of Applications
Containerization of applications is a significant move during cloud migration, suitable for applications such as Dev Test Applications, Multi-Tier Stacks, LAMP applications, or Java or web applications running on-premises. System containers, which share the kernel of the host operating system and provide user space isolation, allow for the installation of different libraries, languages, and databases.
Google Container Registry (GCR)
Google Container Registry (GCR) is a container registry for managing and storing container images, with features like versioning, access control, and integration with popular continuous delivery systems.
Considerations for Cloud Migration
Not all aspects of a business may be suitable for cloud migration due to licensing issues, technology stack limitations, or the inability to virtualize. Businesses should carefully evaluate their current state and desired outcomes when choosing a migration path, with options including all-in-one lift and shift, hybrid approach, private and public cloud, or a combination of these.
