While for security purposes we cannot expose our exact architecture, but we can mention that we use Amazon's state of the art Amazon Web Services cloud for hosting and operating HootBoard. This is the same robust infrastructure that Amazon uses for Amazon.com. Even Netflix is hosted on AWS along with millions on other small and large web applications.
In particularly we use:
Amazon EC2 (Elastic Compute Cloud) for servers
Amazon S3 (Simple Storage Service) for storing files and images
Amazon RDS for Data Storage
Amazon Route 53 for data routing requirements
Amazon ELB for Elastic Load Balancers for load balancing across servers
Amazon Cloudfront for Content Delivery Network Services.
All above server infrastructure, is fire walled to restrict access. You can read more about redundancy features of this infrastructure on https://www.amazon.com/aws
Additionally we use 256 bit TLS 1.2 security certificates where needed so all data is encrypted as it travels over the internet.
So does this mean I can upload anything on HootBoard?
No. While we take all possible steps in our control to protect user data, we recommend users to upload information only as needed. If you haven't done already, review the security settings of your HootBoard with one of our consultants for free. You can use this link to setup a meeting.
