Building Secure Architectures on AWS


Published on

Amazon Web Services (AWS) approaches security using a shared responsibility model with our customers. We manage and control the components from the host operating system and virtualization layer down to the physical security of the facilities in which the services operate. As part of that model, our customers are responsible for building secure applications. We will provide a complete walkthrough from a blank canvas to a secure architecture from a development perspective. No matter the size of your team, you can implement your IT solutions using industry wide best security practices.
