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 […]
In the beginning, the EC2 team in Cape Town, South Africa developed a flat IP network for EC2 instances. Hypervisor-based firewalls separated tenants. Without any way to summarize IP addresses, the network admins’ had a difficult task ensuring developers could reach the instances. The year 2009 ushered in the VPC and the networking components that […]
The online publication The Information reported in mid-July 2018 that AWS was preparing to sell white box switches with built-in connectivity to its cloud offerings. The rumor depressed Cisco stock and triggered a call from Cisco CEO Chuck Robbins to AWS CEO Andy Jassy. AWS confirmed a Cisco spokeman’s statement that AWS is “not actively […]
In Werner Vogels’s keynote at the AWS NYC Summit, he announced the preview release of Bring Your Own IP Address. The VPC feature allows customers to use IP addresses they own as public addresses in the VPC. Is it hard to grasp what exactly this means and how it benefits AWS customers? Before delving in, […]
