Dynatrace is best known for its observability platform, though it plays a role in migrations as well. Their system uses AI to track how applications and infrastructure behave, which is useful during a move and afterward. Organizations rely on it to monitor performance, follow user experience, and identify problems before they become serious.
While it isn’t a migration tool on its own, Dynatrace provides visibility that many companies lose when shifting workloads. It pulls data from across environments and translates it into insights in real time. That way, teams can keep track of what’s happening even when systems are in transition.

5. Google Cloud Dataflow
Google Cloud Dataflow is a managed service that handles both real-time streaming and batch data processing. It runs on Apache Beam, so the pipelines you build aren’t locked into one system and can be run in different environments if needed. A lot of teams use it for moving data between systems, building dashboards, or preparing information for analytics and machine learning.
What makes it handy is how flexible it is. You can set up a simple data pipeline to just move information from one place to another, or create more complex workflows with transformations and aggregations in real time. Since Google takes care of the infrastructure behind the scenes, companies don’t have to worry about provisioning servers or scaling up when traffic spikes.

9. Kamatera
Kamatera takes a different angle by providing the actual infrastructure where applications can be moved and hosted. Their cloud platform offers servers that can scale up or down depending on demand, which makes it easier for businesses to migrate applications without locking into fixed hardware. With data centers spread out globally, they give companies some flexibility in where to run their workloads.
It’s not just about servers, though. They also provide managed cloud services, private networks, firewalls, and load balancers, all of which are important once applications are already in the cloud. The idea is to give businesses the tools they need to keep things running smoothly and securely after migration, while still being able to adjust resources as their needs change.

Conclusion
Wrapping things up, it’s clear that application migration isn’t just about moving software from one place to another. The firms working in this space across Europe bring their own strengths, whether that’s deep expertise in cloud platforms, tools that make complex environments easier to manage, or services that keep applications running smoothly long after the move is done.
What stands out is that there isn’t a single “right” approach. Some companies lean heavily on automation and infrastructure, others focus more on visibility and ongoing management, and a few tie migration into larger transformation projects. The common thread is helping organizations make the shift without losing sight of stability and performance. For anyone considering a migration, the best step forward is to look at which approach fits the way their business already works rather than chasing the flashiest option. In the end, the smoother the transition, the faster teams can get back to focusing on the work that really matters.
