The era of Hadoop is coming to an end as businesses move towards more cost-effective, faster, and easier-to-manage alternatives for big data analytics. Many companies are now considering migration paths such as rebuilding their on-premises Hadoop clusters in the public cloud or migrating to a new on-premises or hybrid cloud alternative. Another option is to move to a modern cloud-native data warehouse, which promises real-time performance and automatic scalability. However, any migration involving large amounts of data should be carefully planned and tested to avoid potential issues. Deploying a multi-dimensional data observability platform like Acceldata can provide powerful performance management features for Hadoop and other big data environments, making the migration process smoother and more efficient.
