Modern cloud ELT platforms such as Fivetran, Stitch, Airbyte, dbt, Snowflake, Azure Data Factory, and Google Cloud Dataflow are often promoted as the default answer for new integration projects. They provide managed infrastructure, strong warehouse integration, and a growing ecosystem of prebuilt connectors. However, they are not always the best fit for organizations that already rely heavily on SQL Server and SSIS or that must keep integrations close to on-premises systems.
SSIS with COZYROC is most competitive when you need event-based processing and webhooks that run near your existing systems. Instead of lifting and shifting everything into a new ELT stack, you can expose your SSIS packages as webhook endpoints using COZYROC Cloud or SSIS NoW, reuse your existing SSIS packages and data flows, and keep your data processing within environments you already control. This is especially attractive when you have large investments in the Microsoft data platform, strict network and security requirements, or teams that are deeply familiar with SSIS.
Many organizations end up with a hybrid architecture:
By clearly separating these roles, you can take advantage of modern ELT tools where they are strongest while still getting full value from SSIS and COZYROC for webhook-driven, operational integrations.
