Cloud-based workflows are revolutionizing creative industries by enabling seamless collaboration and offering unparalleled flexibility. However, for professionals relying on cloud-based tools such as video editing platforms, minimizing latency and optimizing costs is often a critical consideration when establishing or migrating to cloud base workflow.
AWS Global Accelerator addresses this need by offering a solution to enhance performance while keeping expenses in check. Below is an exploration of how AWS Global Accelerator improves Studio in the Cloud latency in a cost-effective manner.
About AWS Global Accelerator
AWS Global Accelerator is a service provided by Amazon Web Services (AWS) designed to improve the availability and performance of global applications. It utilizes the AWS global network infrastructure to direct traffic to optimal endpoints, thereby reducing latency and improving overall user experience. By efficiently routing traffic and minimizing the impact of internet congestion, Global Accelerator enables businesses to deliver low-latency, high-performance experiences to customers worldwide.
Evaluating Latency Improvement
An initial test was conducted to evaluate the impact of AWS Global Accelerator on latency across different regions during video editing tasks and idle periods. The goal was to determine how effectively the accelerator reduces latency to ensure real-time collaboration and user responsiveness in cloud studio environments.
Two scenarios were considered for the latency measurements:
- With Video: Watching a video in the highest resolution on YouTube
- Ide: Doing nothing or minor tasks (such as accessing the file explorer)

Summary of Findings
Variability and Comparative Latency
The test reveals that AWS Global Accelerator has a significant impact on reducing latency variability. This is particularly evident in regions such as Brazil and the USA. Despite the latency already being low in the USA, the accelerator minimized variations, enhancing user experience and ensuring smoother cloud studio operations.
The comparative latency data also underscores the importance of geographical proximity to AWS servers and the effectiveness of the accelerator in optimizing performance across different network environments.
The Impact of Wired vs. WiFi Connectivity
It has been observed that the choice between wired and WiFi connections also significantly influenced latency performance in cloud studio environments. Wired connections, as demonstrated in locations such as Montpellier and Anaheim, offered more stable and consistent latency compared to WiFi connections. This stability can be a critical factor for real-time collaboration where users may be looking for smoother video editing experiences, particularly in high-demand scenarios.
Evaluating Global Accelerator Costs
For the calculations below, the following assumption has been made using the HP Anyware Load Balancing documentation as a reference:
“A 4K/UHD video editorial user or VFX artist may require upward of 50 Mbps on average”.
Note for readers: 50 Mbps is typically not required all the time, but has been chosen as an extreme example.
Scenario
We consider a company that has 5 editors in Europe who need virtual machines for video editing. The bandwidth for accessing these machines averages at 50 Mbps. Below is a calculation of the monthly costs for AWS Global Accelerator if the editors work 8 hours a day, 5 days a week.

- Monthly Cost Comparison:
Summary of Findings
While incorporating AWS Global Accelerator may result in a slightly higher expenditure on AWS, it presents a trade-off: it significantly reduces latency, enhancing performance in cloud-based studio operations. However, as mentioned earlier, it is important to note that the actual cost of Global Accelerator is likely to be lower since the assumed bandwidth requirement of 50 Mbps is an extreme example.
Conclusion
Embracing AWS Global Accelerator helps reduce the latency of cloud-based studio workflows. By optimizing performance and expenses, studios can enhance productivity and efficiency, empowering creative professionals to operate without constraints.
