As more of our customers migrate their on-premises Windows systems to the cloud (IaaS – Infrastructure As a Service), the question arises: Is DymaxIO still necessary? Many customers recognize the need, but some assume it’s no longer relevant. This assumption is false.

Cloud-based Windows systems encounter the same I/O bottlenecks, I/O tax, I/O Blender effect, and fragmentation issues as their in-house physical and virtual systems. Despite the shift in infrastructure, Windows’ inherent write inefficiencies persist, dampening overall performance. Whether running Windows in the cloud, on hyperconverged systems, or all-flash storage, Windows behavior remains consistent, impacting performance.

Even in the cloud, files are always broken down to be much smaller than they need to be, leading to excessive I/O operations that consume valuable IOPS, degrade throughput, and slow down operations. Unfortunately, moving to the cloud doesn’t alleviate these Windows-related challenges.

Fortunately, DymaxIO continues to deliver performance benefits on cloud systems, addressing these issues and maintaining expected performance levels. In some cases, DymaxIO on cloud systems can offer an additional benefit.

Notably, some cloud providers charge based on storage I/O activity. DymaxIO’s IntelliMemory Read caching feature reduces read activity from storage devices, lowering storage I/O activity and potentially reducing costs.

In short, DymaxIO on cloud systems provides the same performance and efficiency benefits as on-premise systems, with the added potential for cost savings. Additionally, customers with current DymaxIO subscriptions can transfer active licenses from on-premise systems to cloud servers, maximizing investment efficiency.

For assistance with license transfers or further information, please reach out to customer support or your account manager. DymaxIO’s flexibility ensures seamless integration into evolving IT infrastructures, reinforcing its value in optimizing performance across environments.
