Amazon Web Services is now available at Illinois for research, instruction, and administrative use. You can request access or log into an account at the University of Illinois AWS service gateway: http://aws.illinois.edu/
Amazon will be on campus regularly to provide guided labs and consultation. More information is available in our Fall 2017 Lab Schedule.
You can contact the Illinois AWS team at firstname.lastname@example.org. We’re always available to sit down and discuss whether AWS is a good fit for your unit’s needs, design solutions, or take feedback on how we can improve the service.
Amazon S3 has been in the news lately:
Top Defense Contractor Left Sensitive Pentagon Files on Amazon Server With No Password
Cloud Leak: How A Verizon Partner Exposed Millions of Customer Accounts
S3’s default configuration does not allow public access to the contents of a bucket, but these stories all feature bucket or object permissions that were open to the world. It’s evident that it’s a common mistake, but how can we avoid it?
S3 presigned URLs are one answer. A single API call will provide a time-limited URL which will allow access to an object, even if it’s otherwise private. Here’s an example:
$ curl https://s3.us-east-2.amazonaws.com/uiuc-presigned-url-example/secret.txt
<?xml version="1.0" encoding="UTF-8"?>
That file is private, so clicking on that link gives an a AccessDenied error. However, with the right access in the hosting account, I can use the AWS CLI to request a pre-signed link:
$ aws s3 presign s3://uiuc-presigned-url-example/secret.txt --expires-in 604800
That returns a long URL which will work for one week from the time it was created.
$ curl "https://s3.us-east-2.amazonaws.com/uiuc-presigned-url-example/secret.txt?X-Amz-Date=20170720T182534Z&X-Amz-SignedHeaders=host&X-Amz-Credential=ASIAIYLQNVRRFNZOCFBA%2F20170720%2Fus-east-2%2Fs3%2Faws4_request&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Expires=604800&X-Amz-Security-Token=FQoDYXdzEJP%2F%2F%2F%2F%2F%2F%2F%2F%2F%2FwEaDOLWx95j90zPxGh7WSLdAVnoYoKC4gjrrR1xbokFWRRwutmuAmOxaIVcQqOy%2Fqxy%2FXQt3Iz%2FohuEEmI7%2FHPzShy%2BfgQtvfUeDaojrAx5q8fG9P1KuIfcedfkiU%2BCxpM2foyCGlXzoZuNlcF8ohm%2BaM3wh4%2BxQ%2FpShLl18cKiKEiw0QF1UQGj%2FsiEqzoM81vOSUVWL9SpTTkVq8EQHY1chYKBkBWt7eIQcxjTI2dQeYOohlrbnZ5Y1%2F1cxPgrbk6PkNFO3whAoliSjyRC8e4TSjIY2j3V6d9fUy4%2Fp6nLZIf9wuERL7xW9PjE6eZbKOHnw8sF&X-Amz-Signature=a14b3065ab822105e8d7892eb5dcc455ddd603c61e47520774a7289178af9ecc"
This is a secret file. Keep it safe.
Presigned URLs can be used to safely share files with collaborators or exclusively display content to logged-in, trusted users on a website. They can’t stop a trusted user from saving content and reposting it elsewhere, so consider the human factor when you’re using them.
Amazon is currently sending out alerts to account holders that have publicly-readable S3 buckets. If we receive a notice, we’ll forward it on to that account’s admin contacts for consideration.
You can now launch G3 instances, the latest generation of Amazon EC2 Accelerated Compute Instances. G3 instances make it easy to procure a powerful combination of GPU, CPU, and host memory for workloads such as 3D rendering, 3D visualizations, graphics-intensive remote workstations, video encoding, and virtual reality applications.
Backed by the NVIDIA Tesla M60 GPUs, G3 instances offer double the CPU power per GPU, and double the host memory per GPU when compared to the most powerful GPU cloud instance available today. This allows you to do complex modeling and 3D visualization analyses such as medical image processing, computer-aided design, or seismic visualization jobs in much less time than possible with any other GPU cloud instance.
ou can launch G3 instances using the AWS Management Console, AWS CLI, AWS SDKs, and third-party libraries. G3 instances are available in three instance sizes in US East (Ohio), US East (N. Virginia), US West (Oregon), US West (N. California), AWS GovCloud (US), and EU (Ireland), with support for more regions coming soon. To learn more about G3 instances, visit the AWS Blog.

Amazon has opened a call for proposals for the 2017 round of Amazon Research Awards (ARA) in a number of areas, including machine translation, natural language understanding, search, robotics, and more. The program is open to faculty members at academic institutions in North America and Europe and awards up to 80,000 USD in cash and 20,000 USD in AWS promotional credits.
Proposal submissions are accepted until September 15, 2017.
For complete information visit the Amazon Research Rewards webpage. Should you complete a proposal, please contact the Illinois AWS team and make them aware so they can provide support.
We’ll be holding free AWS labs throughout the Fall semester. Here’s the full schedule of dates. Times and locations will be updated when available:
- July 12: 2:00 to 4:00 p.m. in the Undergraduate Library ICS Lab
- July 19: 9:00 to 11:00 a.m. in the Undergraduate Library ICS Lab
- August 9: 9:15 to 11:15 a.m. in 27 Illini Hall
- August 23: 2:00 to 4:00 p.m. in 27 Illini Hall
- September 13: 2:00 to 4:00 p.m. in 27 Illini Hall
- September 27: 9:15 to 11:15 a.m. in 27 Illini Hall
During each lab session, you’ll have your choice of topics:
- AWS 101: Introduction to EC2
- Identity and Access Management
- S3 and CloudFront for content distribution
- Relational Database Service
- Automating AWS with CloudFormation
- Introduction to Lambda
- Building clusters with Alces Flight
- Elastic MapReduce
You may run through multiple labs if time allows. An Amazon solutions architect will be on-site with our local staff to offer technical assistance and discuss cloud topics.
Technology Services will grant you access to a shared AWS account for the lab; you don’t need your own. Computers will be available onsite, though you’re welcome to bring your own laptop if you prefer.
Please register here to reserve your seat.
Do you have questions about how you can use Amazon Web Services (AWS) to enhance your research, storage, or website hosting? AWS will host a FREE seminar in Chicago on Wednesday July 26 and Thursday July 27 at the McCormick Place Lakeside Center. To register online or see additional details visit https://aws.amazon.com/summits/chicago/.
This summit is a great, low-cost way to attend technical sessions and workshops, bootcamp training events, and labs. AWS engineers, solutions architects and AWS partners will be present and available throughout the event.
Onsite registration begins at 7:30am on Wednesday followed by labs and the keynote presentation at 9:30am.
