4 min readSep 12


When it comes to deploying OvenStudio LLHLS on the AWS Marketplace, selecting the right EC2 instance type is a critical decision that can significantly impact your streaming performance and cost efficiency. In this blog post, we’ll guide you through the process of choosing the optimal EC2 instance for your OvenStudio LLHLS deployment.

#01. Consider Your Workload and Streaming Requirements

Before diving into EC2 instance types, evaluate your streaming workload and requirements. Factors to consider include:

  • Concurrent Viewers: Estimate the number of simultaneous viewers you expect. This will impact the CPU, memory, and network resources needed.
  • Video Quality: Higher quality streams require more resources. Determine the desired video quality (resolution, bitrate, framerate, and more) of your streams.

#02. CPU and Memory Requirements

For OvenStudio LLHLS, CPU and memory are crucial. Here are some EC2 instance families that offer a good balance between CPU and memory:

  • M5 Instances: These provide a balanced mix of resources, ideal for moderate CPU and memory-intensive workloads.
  • C5 Instances: Designed for compute-intensive tasks, these instances offer high CPU performance.

#03. Network Performance

Since streaming involves transmitting large amounts of data, network performance matters. EC2 instance types vary in their network capabilities:

  • Network Performance Levels: Instances like the C4, C5, M4, and M5 families generally offer higher network performance.
  • Enhanced Networking: Look for instances that support Enhanced Networking, which can improve network throughput and latency.
