Be it the large volume of data or data field mapping issues. Be it the time
duration for the entire restoration or the large size of fact tables and data
validation. On-premise data warehouses always come with their own caveats.
Therefore, migrating from an on-premise data warehouse to a cloud data
warehouse can help you drastically with data modernization.
You can easily manage gazillions of data and get rid of the data mapping
issues and optimize your CapEx & OpEx. Let’s understand how Teradata to AWS
Redshift migration can help you with your data modernization journey.
In order to migrate the on-premise Data Warehouse (Teradata Database) to
AWS Cloud Infrastructure (Redshift Database), you need a well-defined mechanism
in place.
AWS provides Amazon SCT (Schema Conversion Tool) for converting schema and
loading chunks of data for large fact tables by applying conditions for source
data. The time duration is an important constraint for the entire migration
process. You can leverage parallel tasks in SCT for processing different chunks
of data resulting in faster migration of data
Why do you Need to Migrate from Terdata to Redshift for Data Modernization?
By migrating from Teradata to Redshift, you can redesign and rebuild the
system. You can replace complex views and stored procedures with Postgres UDF,
and Perl/Python script translations. This shift also helps you with an
automated end-to-end data validation script to assess the data after migration
inside a stringent validation window.
With the migration from Teradata to Amazon Redshift, you get:
- A user-friendly and highly scalable robust system at
a strikingly lower cost
- An improved and highly satisfactory query
performance
- Better workload management results in faster
performance
- Multiple custom integrations for better
administration and development
- Redshift database can be co-located with S3 data
storage which can access data with a single copy command resulting in a
huge add-on to data engineering productivity
Long-term Benefits of Migrating from Teradata to Redshift
·
By automating the provisioning of administrative
tasks, Amazon Redshift requires less staff time to deploy, manage, and support.
In addition, Redshift has the flexibility to deliver more value to
organizations through more timely delivery of PaaS offerings.
·
Data warehousing operations experience fewer user
and business-impacting outages with Redshift, indicating that organizations
save productive employee time and potential revenue to outages and downtimes.
·
A variable spending model, scalability, and data
compression capabilities reduce the need to potentially overprovision data
warehousing environments while moving to Amazon Redshift. This enables
operational cost savings and helps you reduce your TCO.
Summing Up
Thus, it won’t be an exaggeration to say that migrating from Teradata to
Amazon Redshift can greatly enable you to drive performance efficiency,
innovation, and agility. But how do you seamlessly relocate your humongous data
from on-prem to a cloud data warehouse? You need a data modernization solution
that can help you make this journey smooth.
