Overview
In today’s dynamic business landscape, modernised data ecosystems can enable enterprises to uncover more value to stay competitive, compliant, and agile.
Accelerating transformation, while mitigating risks, with cloud-native scalability, organisations can effectively and efficiently meet evolving business and regulatory needs.
TCS Data Modernization Service on AWS empowers enterprises to seamlessly migrate and modernise their legacy extract, transform, load (ETL), data warehouse (DWH), and data observability systems to modern data environments with cloud-native services and platforms like AWS Glue, Amazon Redshift, Databricks and Snowflake. Powered by generative artificial intelligence (GenAI), and machine learning (ML)-driven observability, the TCS offering accelerates transformation while ensuring data integrity, security, and compliance.
Challenge
Modernising and transforming legacy data management systems and processes is a business imperative for driving agility and unlocking value.
Organisations stand to unlock greater value by modernising their data ecosystems that can keep pace with evolving business needs, regulatory requirements, and rapid technological advancements. Organisations need to achieve greater agility, and scale, by overcoming data migration and modernisation challenges posed by traditional approaches, including:
- Slower, risk-prone, and resource-intensive migration due to complexity of legacy platforms
- Limited visibility into data pipelines in hybrid environments due to fragmented observability
- Regulatory and operational risks due to compliance and security gaps
A modern, AI-powered, and cloud-native approach enables enterprises to overcome these challenges, and accelerate modernisation and transformation while ensuring governance, scalability, and efficiency.
Offering
TCS Data Modernization Service on AWS offers comprehensive capabilities to strengthen ETL, DWH, and data observability systems.
