3 Steps to Accelerate Your Hadoop-to-AWS Cloud Migration

By Van Diamandakis, Jul 23, 2021

Many organizations mistakenly view Hadoop-to-AWS cloud migration as something to complete and check off their to-do list. Instead, you should view the project as adopting a modern data architecture that continually moves data to any location — application, customer, or database. Once the initial AWS cloud migration is completed, you begin consistently replicating your data between multiple clouds and data centers. The goal is for your employees and customers to work with whatever data and application they need — both cloud and on-premises — without needing to know the location of the data or application, because they can complete their tasks easily.

Three keys to a successful Hadoop-to-AWS cloud migration

1. Avoid “big bang” events

When executing a Hadoop-to-AWS cloud migration, the “big bang” mindset carries the potential for unexpected business disruption and inability to rollback in a timely fashion. The ability to access the same data both from the cloud and from on-premises applications enables users to continue working without realizing they’ve been migrated to the cloud.

2. Set proper expectations for acquiring a working knowledge of the cloud

Many companies underestimate the working knowledge needed for cloud environment services, configurations, and operations. This causes longer remediation times and a lack of developing best practices. Data replication simplifies the process of migrating data, allowing for time to develop an initial expertise in the surrounding cloud environment.

3. Use data replication technology specialized for Hadoop migration

While there are many data replication technologies on the market, using a technology designed specifically for migrating Hadoop from on-premises to the cloud provides many benefits. Look for data replication technology that has been proven with the Hadoop Distributed File System (HDFS) and cloud object stores, such as Amazon S3. Features such as drag-and-drop interfaces with monitoring and alert notification are especially beneficial during such a complex migration.

When looking for a specialized tool, look for a tool that supports bi-directional updates, so data on both the cloud and on-premises stays synced both during and after the migration. You should also determine if a tool maintains data share in both locations, allowing applications to have multiple options for cloud migrations. By using an independent data replication vendor for a Hadoop-to-AWS cloud migration, you’ll have support for an open architecture that in the future lets you more easily manage data for multi-cloud environments.

Plan for a hybrid cloud mindset

Without an absolute mandate to be completely out of a data center by a specified date, cloud migration projects may span years and never fully attain a 100% cloud-only platform. Companies find themselves in a hybrid cloud situation at the onset of the cloud migration progress. Over time, not all applications will run in the cloud due to security and/or compliance regulations. Therefore, having a hybrid-cloud mindset from the beginning will lead to decisions that won’t require adjustment or rework in the future.

  • Expect that not all data and applications will migrate fully to the cloud platform, while new applications will be developed in a cloud-first strategy.
  • Accept that migrating Hadoop data may become managing smaller Hadoop cluster footprints on-premises with a flexible, easier-to-manage hybrid cloud data technology stack.
  • Curate on-premises Hadoop data sets with selective data replication — not all data, applications, or user groups can migrate to the cloud.
