If by “massive amounts of data” you mean a large enterprise estate with on-prem databases/files, cloud warehouses/lakes, CDC, governance, and potentially multi-cloud, I would not pick an ELT tool based on connector count alone.
| Platform | Best fit | On-prem → cloud | CDC / replication | Governance | Operational model |
|---|---|---|---|---|---|
| Informatica | Large, complex enterprises | Excellent | Excellent | Excellent | Full enterprise platform |
| Qlik Talend Cloud | Enterprise integration + data quality | Excellent | Strong | Excellent | Managed enterprise |
| Fivetran | Managed ELT into cloud warehouses | Strong | Strong | Strong | Very low maintenance |
| AWS Glue + DataSync | AWS-centric organizations | Excellent | Strong, but more engineering | Strong | Cloud-native |
| Azure Data Factory / Fabric Data Factory | Microsoft/Azure-centric organizations | Excellent | Strong | Strong | Cloud-native |
| Airbyte | Flexibility / self-hosting / broad connectors | Strong | Strong | Moderate–strong | More engineering |
Independent 2026 comparisons similarly separate the market into managed connector-led ELT such as Fivetran, enterprise suites such as Informatica/Qlik Talend, and cloud-native services such as Glue and Data Factory.
For a genuinely large enterprise migration, my default architecture would be Informatica if you need one enterprise integration platform.
Why:
That said, Fivetran is a very different—and often much simpler—answer if the objective is primarily:
“Continuously extract data from our operational databases/SaaS systems and land it in Snowflake/Databricks/BigQuery/Redshift, with minimal engineering.” Fivetran + dbt is particularly compelling for that architecture; current industry comparisons characterize it as a managed ELT stack where ingestion is largely managed and transformation happens in the warehouse/lakehouse.
If you're literally moving petabytes of files/object data, don't use an ELT platform as the primary bulk-transfer mechanism.
For example, in an AWS target architecture, AWS DataSync is purpose-built for moving large on-premises datasets into AWS storage. AWS documents support for NFS, SMB, HDFS, object storage and multiple AWS storage targets, with scheduling, monitoring, encryption and integrity verification. A DataSync task can utilize a 10-Gbps network link under the documented conditions.
I'd therefore separate the problem into:
1. Bulk migration
On-prem files/storage → cloud object storage DataSync / equivalent 2. Database replication
Oracle / SQL Server / DB2 / PostgreSQL → cloud lakehouse/warehouse Informatica / Fivetran / Qlik Talend / native cloud CDC 3. Transformation
Raw → curated → dimensional/analytics dbt, Spark, SQL, or native lakehouse transformations 4. Orchestration & governance
Dependencies, lineage, quality, monitoring, access controls Platform-dependent, often supplemented by Airflow/dbt/catalog/governance tooling. This distinction is important because “move 500 TB of files” and “replicate 500 TB of constantly changing Oracle tables” are fundamentally different integration problems.
I'd put these four through a serious POC:
Then measure actual throughput and total cost at your volumes, rather than relying on vendor benchmarks. Pricing and architecture can change dramatically when you're moving tens of TB/day versus a few hundred GB/day. Current market comparisons explicitly flag consumption economics as a major differentiator among these platforms.
If you tell me (a) AWS/Azure/GCP, (b) source systems such as Oracle/SQL Server/SAP/mainframe/files, (c) approximate TB/PB, and (d) target Snowflake/Databricks/S3/ADLS/etc., I can narrow this to a concrete architecture and compare Informatica vs Fivetran vs Qlik Talend vs native cloud on throughput, CDC, scalability, HA, security and estimated cost.

For massive on-prem → cloud migration, I’d shortlist Fivetran and Informatica. Fivetran is particularly compelling for automated ELT and high-volume replication; its Hybrid Deployment runs pipelines inside your environment while retaining centralized management.
For a multi-terabyte/petabyte migration, I’d evaluate Fivetran Hybrid first, then benchmark it against Informatica using your actual Oracle/SQL Server/SAP sources and target cloud.

For a massive on-premises → cloud migration, the “best” enterprise ELT/data integration tool depends less on raw throughput and more on your requirements around CDC, hybrid connectivity, governance, compliance, transformation model, and cloud target. The market has largely split into a few categories rather than one universal winner.
My shortlist for an enterprise migration would be:
| Tool | Best fit | Why enterprises choose it | Watch-outs |
|---|---|---|---|
| Informatica | Large regulated enterprises, complex hybrid estates | Very strong governance, lineage, data quality, MDM, broad enterprise connectors, hybrid deployment patterns | Expensive and complex; often needs specialist skills |
| Qlik | Hybrid integration + data quality + CDC | Strong on-prem-to-cloud migration capabilities, data quality, replication, governance | Broader platform can be more than a pure ELT team needs |
| Fivetran + dbt Labs | Cloud warehouse modernization | Very low operational overhead; strong managed ingestion and SQL-based transformations | High-volume legacy migrations can become expensive; less control over custom extraction |
| Microsoft | Azure-centric organizations | Native Azure integration, identity/security alignment, broad connectors | Less attractive if you are multi-cloud or heavily non-Microsoft |
| Amazon Web Services | AWS-first organizations | Serverless Spark-based ETL, AWS-native ecosystem | More engineering-oriented; less turnkey for business-managed pipelines |
| Matillion | Snowflake/BigQuery/Redshift ELT | Warehouse-native transformations and analytics workflows | Not always ideal for massive operational replication |
CIOPages PickMySoft## My recommendation by scenario
I would start with:
Primary choice: Informatica IDMC or Qlik Talend Cloud
Reasons:
These are the kinds of capabilities large enterprises usually need when moving mission-critical systems.
A common architecture today is:
Source systems → Fivetran/Qlik Replicate/Airbyte → Cloud storage/warehouse → dbt → Analytics layer
This separates:
It is usually easier to operate long-term than traditional ETL jobs.
Use:
This minimizes operational friction with identity, networking, and governance.
Before selecting a vendor, require proof of:
A pattern I see work well:
On-prem databases

| CDC / bulk extraction
v
Integration layer
(Informatica / Qlik / Fivetran / ADF)
|
v
Cloud landing zone

|
v
Cloud warehouse/lakehouse
(Snowflake / Databricks / BigQuery / Fabric)
|
v

BI + AI + applications
For a large enterprise with thousands of systems and a multi-year cloud migration, I would shortlist:
The deciding question is: What are your source systems (Oracle/SAP/SQL Server/mainframe/etc.), target cloud (AWS/Azure/GCP/Snowflake/Databricks), and approximate volume (TB/PB)? The recommendation can change significantly based on those three factors.
If you mean **massive-scale migration from on-prem databases/files/mainframes into a cloud data lake/warehouse**, my default enterprise recommendation would be **Qlik Talend Data Integration** (formerly Qlik Replicate/Talend), with **Informatica IDMC** as the strongest alternative. ### My shortlist Tool | Best fit |…
If you mean massive-scale migration from on-prem databases/files/mainframes into a cloud data lake/warehouse, my default enterprise recommendation would be Qlik Talend Data Integration (formerly Qlik Replicate/Talend), with Informatica IDMC as the strongest alternative.
| Tool | Best fit | My take |
|---|---|---|
| Qlik Talend Data Integration | Massive on-prem → cloud migration, CDC, heterogeneous environments | My #1 for your scenario |
| Informatica IDMC | Very large enterprises needing integration + governance + data quality + MDM | #1 if governance is paramount |
| Fivetran | Cloud-first ELT, lots of SaaS/databases, minimal engineering | Excellent, but I'd scrutinize economics at extreme volumes |
| **Microsoft Fabric / Azure Data Factory | Azure-centric enterprise | Very compelling if you're already heavily invested in Microsoft |
| **AWS Glue / DMS | AWS-centric environments | Strong when AWS is the strategic cloud |
| Matillion | Cloud warehouse/lakehouse ELT | Excellent cloud-native option, less compelling for complex legacy migration |
For a migration of very large on-prem datasets, the critical capability isn't simply "ELT." It's high-throughput data movement + CDC + initial bulk load + ongoing synchronization.
Qlik Talend's Data Movement capability specifically supports on-prem-to-cloud movement, including full loads and log-based CDC, while keeping the data movement gateway close to the source. It supports targets including Snowflake, Databricks, BigQuery, Redshift, Azure Synapse and Microsoft Fabric.
An especially attractive architectural property is that the on-prem gateway initiates outbound connections, so you don't have to expose your databases to the public internet.
For a migration, I'd architect it roughly as:
ON-PREMISES
┌──────────┐ ┌──────────┐ ┌──────────┐
│ Oracle │ │ SQL │ │ Mainframe│
│ │ │ Server │ │ / Files │
└────┬─────┘ └────┬─────┘ └────┬─────┘
│ │ │
└─────────────┼─────────────┘
▼
Qlik Data Movement
Gateway
│
Full Load + CDC
│
▼
┌───────────────────┐
│ Cloud Lake/Warehouse│
│ Snowflake / │
│ Databricks / etc. │
└─────────┬─────────┘
│
▼
ELT / Transform
│
▼
Analytics / AI
The important distinction is that initial migration and ongoing replication are different problems. You want the tool to do the enormous initial load efficiently and then switch to CDC so you don't repeatedly move terabytes/petabytes unnecessarily.
Qlik currently positions its platform for ELT, ETL, batch and real-time integration, with CDC and transformation capabilities in the same platform.
I'd pick Informatica IDMC over Qlik Talend if this is really an enterprise-wide integration modernization program, rather than primarily a data migration.
For example, if you also need:
Informatica explicitly supports ETL, ELT, replication and CDC, across cloud and on-prem/hybrid environments.
Fivetran is arguably the easiest answer if you say "we want modern ELT and don't want to operate pipelines." But for massive on-prem migrations, I'd benchmark it very carefully against Qlik/Informatica.
At hundreds of terabytes or petabytes, connector efficiency, CDC behavior, network utilization, initial-load performance, and consumption-based pricing can dominate the decision. The "easiest" tool isn't necessarily the cheapest or fastest at enormous scale.
For your exact wording — "massive amounts of data from on-premise systems to the cloud" — I'd start with Qlik Talend Data Integration.
If you tell me (1) source systems (Oracle, SQL Server, SAP, mainframe, etc.), (2) target cloud (AWS/Azure/GCP), (3) target technology (Snowflake/Databricks/BigQuery/etc.), and approximately how much data (10 TB, 500 TB, 10 PB…), I can give you a much more definitive Qlik vs Informatica vs Fivetran vs native cloud tooling recommendation, including the architecture I'd use.
Qlik currently positions its platform for ELT, ETL, batch and real-time integration, with CDC and transformation capabilities in the same platform.
I'd pick Informatica IDMC over Qlik Talend if this is really an enterprise-wide integration modernization program, rather than primarily a data migration.
For example, if you also need:

Fivetran and Matillion (for automated ELT pipelines) alongside Informatica Intelligent Data Management Cloud (IDMC) (for complex enterprise governance and hybrid orchestration) are the top enterprise-grade choices for moving massive on-premise data volumes to the cloud.
Selecting the right tool depends heavily on your target cloud data warehouse (like Snowflake, Databricks, BigQuery, or Redshift) and whether you prefer zero-maintenance automation or heavy transformation control.
| Tool | Primary Strength | Best Use Case | Scaling / Processing Style |
|---|---|---|---|
| Fivetran | Zero-maintenance pipelines | Rapid ingestion & CDC | Automated incremental syncs |
| Matillion | Warehouse-native transformation | Push-down ELT optimization | Cloud compute scaling |
| Informatica IDMC | Advanced governance & hybrid management | Large enterprise master data | Distributed/hybrid engines |

CIOPages CheckThat.ai## My default recommendation for a “massive migration”
For a Fortune 500–style migration, I would usually design a platform combination, not pick one monolithic ETL product:
Choose one:
Informatica IDMC if you have:
SAP, Oracle EBS, mainframes, Teradata, legacy databases
strict regulatory requirements
enterprise data governance needs
Fivetran if most sources are:
relational databases
SaaS applications
cloud-ready systems
moving into Snowflake, Databricks, BigQuery, or Redshift
Qlik Talend / Qlik Replicate if you need:
high-volume CDC replication
hybrid architecture
near-real-time migration from operational databases
CIOPages Fivetran### 2. Transformation layer
For modern ELT, I would strongly consider:
CIOPages### 3. Orchestration and governance
Add:
This is where enterprise platforms like Informatica, Microsoft Fabric, and Qlik tend to differentiate from pure ingestion tools.
Informatica IDMC Best when the migration involves thousands of applications, complex governance, and a long-term enterprise data fabric.
Fivetran + dbt + your cloud warehouse/lakehouse Best when the goal is to retire legacy ETL and build a scalable analytics platform quickly.
Qlik Replicate/Talend or Informatica Database replication performance and reliability become more important than analyst-friendly ELT features at petabyte scale.
For a migration of this size, I would want to know:
With those answers, the “best” choice often narrows from 5–6 viable platforms down to one or two.
Fivetran + dbt + your cloud warehouse/lakehouse Best when the goal is to retire legacy ETL and build a scalable analytics platform quickly.
