Make your Modern Data Lake the center of your data migration strategy

Modern data lakes or data lakehouses combine advanced data warehouse capabilities for scaling high-concurrency SQL analytics with the flexibility and cost-effectiveness of a cloud data lake, consolidating your data architecture. It becomes the center of gravity for data but not the single source system. With a modern data lake, organizations can leverage open table and file formats from technologies like Iceberg, Delta Lake, or Hudi, not only as a cost-effective object store and landing zone for interactive analytics you would expect from a data warehouse but also for prescriptive, predictive, and cognitive analytics. Modern data lakes also help usher in a new era of efficiency, increased productivity, and cost optimizations by phasing out legacy systems and adopting new systems built in and for the cloud.

Traditional data migration processes vs Starburst

Traditional data migration process

With a data migration process, the downstream requirements (e.g., BI, reporting, data science) are tightly coupled with the cloud data warehouse schemas and, thus, the ETL processes that create them. This would be okay if not because these downstream workloads frequently change, potentially leading to data integration issues. Building and maintaining pipelines is not necessarily difficult, but it can become time-consuming, resource intensive, and tedious at scale. This requires extensive planning and modeling of what-if scenarios to get as much of the ETL/schemas right the first time to avoid breaks and downstream impact leading to downtime.

How Starburst simplifies the data migration process

Starburst simplifies the entire migration process. First, with the federation, before moving a single table, you can create a semantic federation layer for all of your source tables. That lets you start immediately plugging in your downstream client tools and applications and working out your downstream business requirements. Repointing single tables or entire schemas is simple as you start the data migration process to a low-cost cloud object storage.

Best practices for data migration

Besides the volume of data and location, it is crucial to inventory current processes, data structures, and safeguards. Key considerations for your data migration strategy should include business requirements, data value, data type, governance, and complexity.

Understand the data you are migrating

Data quality is fundamental to business success. The first best practice when migrating data is understanding the data you are moving from one system to another. This involves assessing the source and target systems, identifying the data formats, types, volumes, dependencies, and relationships, and evaluating the data quality and integrity.

Define a clear strategy

Data migration is not a one-time event but a continuous cycle that requires planning and execution. The second best practice when migrating data is to define a clear strategy that aligns with your business goals, requirements, and constraints. This involves setting the migration project’s scope, objectives, timeline, budget, and roles and responsibilities.

Have a disaster recovery plan

Data migration can be risky and result in data loss or corruption. Create a backup of your data before you migrate it. This may also include the need for continued source data replication. This can help you recover your data in case of any errors or failures during the migration process.

Migrate data in batches

Data migration can be lengthy and complex, especially if you have a large amount of data to migrate to your new environment. The fourth best practice when migrating data is to migrate data in batches rather than all at once. This can help you reduce the migration time, minimize the impact on business operations, and monitor and troubleshoot the migration process more efficiently.

Use the right data migration tools

Data migration can be challenging and tedious, requiring much manual work and expertise. The fifth best practice when migrating data is determining which types of data migration tools are needed and the best vendors to provide them. The focus should always be on automation and simplification of the data migration process without incurring massive costs. Many tools are available for data migration, such as cloud-specific data transfer services, other migration software, and professional services. Consider your SQL-based semantic layer over all the data sources to operate as a single access point at this stage. The data consumption layer allows for the underlying data locations, formats, and technologies to change, without the users needing to be aware.

Test your migration process

Data migration can be prone to errors and failures that can affect the quality and usability of your migrated data. The sixth best practice when migrating data is to test your migration process before you move your data to production. This involves validating your migrated data and systems’ functionality, performance, security, and compatibility.

Test your migrated data thoroughly before using it in production

Data migration can result in changes or discrepancies in your migrated data that can affect your business outcomes. The seventh best practice when migrating data is to test your migrated data thoroughly before using it in production. This involves verifying your migrated data’s accuracy, completeness, consistency, and integrity.

Keep your data flowing throughout the migration

Downstream business applications and teams should not experience downtime during migrations. The eighth best practice is to ensure business-critical applications, dashboards, reports, and teams continue to access relevant information without duplicating your entire data architecture.

Caution: Two data groups for special migration consideration

Two groups of data may not be worth the migration headaches. It is crucial to have a clear data migration strategy that defines the scope, criteria, and methods for selecting and migrating data. This strategy should consider the trade-offs between the costs and benefits of migrating different data workloads.

Data for applications managed on-premises

For example, a product team may continue to run a web application on-premises while its smartphone app sibling is deployed to the cloud. Tables supporting both applications, like “customers” or “order history,” may need to persist on-premises for the web application until the web application is also ready to be migrated to the cloud.

Regulated data

Data that may be subjected to regulatory requirements or could be sensitive, outdated, inaccurate, incomplete, or irrelevant to the business’s future operations must be maintained. Migrating this data can cause errors, performance issues, compliance risks, and have significant cost implications.

It may be advantageous to embrace a hybrid cloud approach and persist data on-premises and utilize Starburst to bridge the cloud and on-premise data sets to increase the capacity of a migration team, speed the migration, prevent data or workload outages and help avoid data duplication, performance, and compliance issues.

Hadoop

A modern cloud data lake strategy that helps simplify and streamline the data migration from Hadoop to the cloud. It enables a seamless data transition from HDFS to a cloud-based storage service without requiring data format or schema changes. It can also allow a seamless transition of the applications, pipelines, and tools from MapReduce, Hive, Spark, and other frameworks to Starburst, which because of the Trino core, can query any data source without data movement or duplication. Starburst also integrates with other open-source tools and frameworks, like Apache Iceberg, Delta Lake, and Apache Hudi, to make the modern data lake a reality.

Data Warehouse

As a part of the data migration process, leading cloud data warehouses recommend first moving your data into a cloud data lake like S3 or Azure Data Lake Storage for staging before transferring the data into their proprietary vaults, making it easy for data to go in, but not so much for it to come back out. Because Starburst provides warehouse-like capabilities on the data lake, you don’t need to put all your data into an expensive and rigid cloud data warehouse. You decide which, if any, data should move into a cloud data warehouse while being able to run high-performance SQL analytics directly on your cloud data lake.

Activate your data on all major clouds

Starburst simplifies data migrations to all three major cloud providers and, once done, activates the data in and around the modern data lake. Choosing the right cloud platform provider can be daunting, with each offering massively scalable object storage across their global data centers, data lake orchestration, and managed Spark, Trino, and Hadoop services. You may opt for a multi-region and multi-cloud architecture, depending on your requirements. Learn how Starburst partners with each cloud to maximize the return on your migration.
