At re:Invent, various Amazon speakers tout the security, availability, and performance of the AWS Global Backbone, a private Internet Protocol (IP) network purpose-built for moving customer data across the world. The talks are pure gold for network engineers as Amazon is very transparent in discussing the design of the backbone. Why should AWS customers care […]
Looking back over the last several years, we’ve seen we’ve seen considerable hype surrounding companies going “all-in” on the public cloud. Large companies such as Capital One and Netflix are industry leaders in this respect and deservingly so. The effort involved is monumental and its effect on IT consumption within those organizations is transformational. For […]
AWS provides the mechanisms to create VPC designs that run the gamut of the complexity spectrum. You can deploy your application in a single VPC with only public subnets. Other applications may be better suited to a collection of VPCs with both public and private subnets. You can use VPCs as building blocks for large-scale […]
At Konekti, we’ve observed that many of our clients prefer to use terraform to create AWS infrastructure. We understand this choice. Terraform’s cross-platform nature and use of modules make it very flexible and easy to adopt. The purpose of this post is to demonstrate how easy it is to create two VPCs and then create […]
Amazon provided infrastructure architects a transformative VPC component in its November 2018 introduction of the AWS Transit Gateway (TGW). The TGW can be used to simplify previously complex and management-intensive architectures such as those involving Transit VPCs. In this post, I’ll use terraform to create a full mesh of connectivity between four VPCs in a […]
Humans err. In working on AWS infrastructure, performing tasks in the Console clearly leaves room for mistakes. Even carefully crafted automation can contain defects. In this post, I’ll describe a feature AWS offers that you can use when you accidentally release Elastic IP (EIP) assigned to your account. I discussed the importance of fixed IP […]
In testing various virtual appliances on the AWS Marketplace, we realized that having an EC2 instance with a GUI helps in experimenting with the features of the appliances. We can use the GUI to manage the appliance on an inside interface as many appliances are GUI-centric. Another use is testing web traffic filtering with an […]
re:Invent 2018 was a blast! It’s great to have an event in which so many members of the AWS ecosystem assemble each year. This was my second re:Invent conference. I am impressed at the logistical improvements Amazon made. With so many attendees, it’s definitely a challenge navigating the events. I highly recommend attending the chalk […]
Developers typically do not have a background as network engineers. While Amazon has done yeoman’s work in simplifying thenetwork components of the VPC, the fundamental nature of networking in application delivery is such that developers will never be completely relieved from network-related considerations. A basic component of networking is the use of IP addresses to […]
AWS announced massive enhancements to its core networking capabilities at re:Invent 2017. Inter-region VPC peering, PrivateLink, and the Network Load Balancer topped the list a year ago. Predicting that significant change is in store for networking at re:Invent 2018 doesn’t require clairvoyance. At Konekti, we have many opportunities to talk to AWS customers at various […]
