Amazon Web Services

Amazon Web Services is well suited for companies that don't want to have deal with physical infrastructure and want a high level of security and availability. In most cases Amazon Web Services is a great option for most, but may not be an option if you have met the tipping point of physical cost vs. Amazon Web Services cost. It may end up being a better option in the long run to manage the infrastructure yourself if the cost per hour of Amazon Web Services is greater than what you can provide if your level of availability is equal to or greater than Amazon Web Services.

SimScale

SimScale is awesome for someone who wants to spin up and use CFD, FEA, or Thermal Modeling quickly and with a lot of support. It doesn't require Linux or specialized computing knowledge to use, unlike many other reasonably-priced options for CFD. It also gets rid of the need for expensive computing equipment as the computing is done completely in the cloud. If you are willing to make your models public, they also offer a free version which contributes to the public database of possible models. If you need to model something which needs to have a large amount of customization or requires very extensive computing capacity, SimScale is unlikely to be the best way to go.

Pros

  • Complete Failover and Disaster Recovery services which scale to your desired need
  • Several service level options from dynamic storage pricing to pre-allocated
  • Customer service responsiveness -- issues are resolved with a quick email or phone call rapidly

  • Amazing support team to help with modeling and troubleshooting
  • Database of example projects is great for gaining ideas on how different scenarios can be modeled within the tool
  • Affordable CFD tool - with computing done in the cloud it allows for complicated modeling to be done without expensive equipment!
  • The browser interface is much more intuitive and faster to learn and use than many other CFD tools. Significantly easier than OpenFOAM, which is its backend.
  • Great training for new users

Cons

  • Occasionally, we disagree with their roadmap priorities. For example, we really needed Content-Based Routing added to ELB to support our multitenant implementation. The AWS architects agreed that it was a mainstream, valuable request and hinted that they were trying to get it onto the roadmap, but 15 months later there's still no sign of it. I'm sure they have their reasons, but it's a strange and annoying hole in an otherwise invaluable service.
  • AWS has had well-publicized outages that have broken the promise of true zone (datacenter) isolation. This was supposed to have been impossible - if you had instances running in two zones within a region, you thought had a solid survivability story. We were forced to react by building out additional redundancy that increased costs beyond our original design estimates. AWS claims to have resolved the problem, but we haven't been confident enough to spin down the extra servers yet.
  • There are annoying resource limits, presumably in place to prevent hackers from allocating huge numbers of resources on a compromised account. The problem is that raising the resource limits requires manual action to be taken, and can have a severe impact on production software if your ops team isn't meticulous in checking the limits. As of the last time I checked, these limits weren't available via API, making it impossible to create alarms whenever we get close to exceeding our resource limits.
  • AWS is relatively infamous for their poor communications during outages. Their status page will occasionally go without an update for 45 minutes, while half your customers are dead in the water. This is - obviously - infuriating.

  • The computing functionality tops out at 32 cores, which is typically more than enough but has caused some limitations in the most complicated CFD scenarios that I wanted to model.
  • There have been a few pieces of open FOAM functionality (which is SimScale's CFD backend) that haven't yet been migrated into SimScale, so flexibility in modeling is slightly reduced from open FOAM. But this appears to be changing and evolving quickly.
  • The viewer for final analysis is somewhat limited. This is ok because the results can be downloaded and analyzed in full in Paraview, which is fully functional but takes more time than viewing in the browser window.

AWS is very reliable, and will scale as needed with an organization. We have yet to experience any downtime. Despite a higher than expected monthly outlay, we will likely continue to use it

The management console is the weak part of the service in my experience. It is adequate but slow.

Performance

AWS does not provide the raw performance that you can get by building your own custom infrastructure. However, it is often the case that the benefits of specialized, high-performance hardware do not necessarily outweigh the significant extra cost and risk. Performance as perceived by the user is very different from raw throughput.

Alternatives Considered

We looked into other server hosts, but the cost was out of our budget. We were quoted a monthly fee of $500 to $750, plus an initial fee of over $1,000. AWS made the most financial sense as well as other reviews and recommendations

SimScale is much faster to spin up on than OpenFOAM. Ansys CFD tools are much more expensive! Both tools require expensive computing equipment to run, which SimScale does not!

Return on Investment

  • Positive: Faster provisioning of infrastructure.
  • Positive: Lower upfront costs.
  • Negative: Integration of AWS to enterprise apps.
Billy Tiangco profile photo
  • We've been able to iterate through a large number of designs more quickly than we would have without a CFD simulation, and also compared to the time it would have taken to prepare most other CFD simulations.
  • Affordable price, and it prevented us from needing to invest in expensive computing equipment.
  • Help from the support team also sped up the process of modeling different scenarios!
