DESCRIPTION
We are looking for Cloud and Database experts that will help companies migrate database workloads to the cloud while modernizing applications and existing architectures.
With the increasing demand of modernization and cloud native solutions, many organizations are migrating to the cloud for greater agility, security and scalability.
The Cloud DB Migration practice is handling projects of assessing Oracle and MS SQL server databases to determine migration complexity and build a migration plans to Google Cloud Platform, Amazon Web Services and Microsoft Azure.
EPAM has a first-of-its-kind cloud migration assessment tool that helps companies analyze database environments and generate a visual cloud migration roadmap to accelerate database migration to the cloud.
Our tool “migVisor” helps identify the best migration path for each database. Using sophisticated scoring logic to rank databases according to complexity, migVisor assesses databases on configuration, schema, business logic and proprietary database features and identifies potential migration challenges and suggests appropriate workarounds.
migVisor dynamically analyzes and compares source databases for support and compatibility with multiple cloud-native, PaaS-based and IaaS-based targets – such as Cloud SQL, Aurora, RDS, EC2, PostgreSQL and MySQL – and automates database migration assessments and source database discovery.
Besides databases and cloud, we are automating our tasks as much as possible using python, this helps us get more value to the customers with short timelines.
