Cloud rendering, in a nutshell

If cloud computing is a technology that allows users to access and use computing resources over the internet, cloud rendering takes this one step further by leveraging these remote computing resources to render 3D graphics and animations. Instead of rendering 3D scenes on a local computer, the data parsing and processing are done on remote servers in the cloud.

The benefits of this are felt the most in rendering 3D animation, since instead of rendering one image after another in sequence on a single machine, all images or frames that comprise an animation can render concurrently. All of the final output is then sent back to the user’s workstation, to be edited further before being converted into a video. This means a complex scene that would take over an hour for every frame in the sequence would finish rendering in just a little more than an hour since all the frames are rendering at the same time.

In short, cloud rendering refers to the process of parallelizing rendering digital graphics and animations by having multiple machines each render a frame or even sections of a frame on remote servers over the internet. A local computer or workstation no matter how powerful would still need to render frames one after the other. This allows for more efficient and cost-effective rendering, as well as the ability to tap into a large network of computers for increased processing power.

Why go cloud?

While cloud rendering services offer many advantages over maintaining an on-premise render farm, one of its biggest draws is the freedom from upkeep costs.

Traditional render farms require a large upfront investment in hardware, software licenses, and IT infrastructure to set up and maintain the rendering farm. In contrast, cloud render farms provide access to computing resources on a pay-per-use basis, allowing for greater flexibility and scalability in resource allocation.

Additionally, traditional render farms typically require a significant amount of time and resources to set up and maintain, while cloud render farms can be set up quickly and easily without any hardware or software installation. However, the cost of using cloud render farms can quickly add up if the project requires a large amount of computing resources or if the rendering time is extensive.

Here’s a hypothetical loose breakdown of costs for maintaining a traditional render farm and using a cloud rendering service:

Traditional render farm:

  • Hardware costs: $50,000 — $100,000+
  • Software costs: $10,000+
  • Electricity costs: $500 — $1,000+ per month
  • Cooling costs: $500 — $1,000+ per month
  • Maintenance and repair costs: $2,000+ per year
  • IT support costs: $2,000+ per year
  • Render farm manager salary: $40,000+ per year

Total cost per year: $80,000 — $150,000+

Cloud rendering service:

  • Cloud rendering costs: $0.10 — $1.00+ per GHz hour
  • Data transfer costs: $0.02 — $0.12+ per GB
  • Licensing costs: Included in the rendering costs
  • No hardware, electricity, or cooling costs
  • No maintenance or repair costs
  • No IT support costs
  • No render farm manager salary

Total cost per year: $10,000 — $50,000+

Of course, these costs will vary depending on the size of your render farm or the scale of your rendering needs. However, in general, using a cloud rendering service can be a more cost-effective solution, particularly for small to medium-sized businesses or freelance artists.

Advantages of cloud rendering

While local or in-house render farms have been and continue to be used by some larger studios, cloud rendering can give smaller studios and individuals a much-needed competitive edge. Some of the advantages it offers are:
