Thanks for the interest! Hannah covered most of your questions fairly well, but I’ll try to fill in some extra details. Obviously nothing is set in stone and answers will change as we hear from the community.
Am I correct that Cesium.com is an AGI-hosted SAAS setup, and that anything created through Composer will be hosted and served by Cesium.com?
The “REST API” section says: “For developers, the processing, hosting, and analytical capabilities that power cesium.com will also be available as a set of REST services for use in custom applications (Cesium-based or otherwise). Almost anything you can do on cesium.com will also be available programmatically through the API.” Are those APIs also directly hosted on Cesium.com, and/or will they be available in a self-hosted format?
In addition to the hosted cesium.com (which is on AWS infrastructure), we’ll have on premises/enterprise solutions for self-hosting and possibly private hosted solutions (via the AWS marketplace). We’re still exploring our options here and feedback from the community will help drive priority. We’re developing on all 3 major platforms (Windows/Mac/Linux).
- Will there be a way to export Composer projects into a more “standalone” environment, either in terms of hosting or code development?
Ultimately, yes, but the exact details haven’t been decided yet. We’ll have data export (i.e. export this specific terrain dataset) before we have full project export.
- What sort of usage limits are there on the services?
While not finalized, our current strategy is that the only limitation is the size of the source data uploaded. Number of API calls or how much data you download will not affect pricing. So if you have an account that allows 100GB of data, you can upload as much raw imagery, terrain, vector data, models, etc… as you want up to 100GB, but you won’t gain lose any features/converters for being on a 10GB or 500GB plans (exact quotas still TBA). It’s a flat monthly/yearly rate. I’m sure the beta will help us evaluate how well this strategy works in practice but our goal is to keep pricing simple and easy to understand.
In addition to subscription level, we plan to have a marketplace of curated data that will be available for subscription. Lots of it will be free, but certain curated datasets (either created by us or provided by new business partners) will be available for a monthly or yearly fee. We again hope to have this be flat rate pricing, but that might have to depend on the exact data product. Exact details here are a lot less clear, but expect to hear more as it solidifies in the coming months.
- What’s the client-side tech stack behind the new site?
We’re hoping to have a full breakdown of our stack in a future blog post (hopefully one of many regarding cesium.com). It could be considered old-school my many people, but we’re solving hard data and visualization problems, so the goal was to have a tried and true tech stack to build on first.
