When organizations start using AWS, they may initially use a single VPC and a very simple network implementation. In many cases, however, companies are leveraging multiple VPCs, regions and accounts. Companies are also connecting cloud networks to corporate headquarters and remote locations. They may even be connecting different cloud providers. This presentation will consider some of these use cases and the implications of connecting different networks. Material covered will include security considerations, sample architectures and tools that can help protect your account and your data.
