Options For Connecting Your Private Cloud

The impulse to move absolute everything to the public cloud is coming to an end. Many companies are re-evaluating their strategies and adopting a hybrid model by bringing or migrating their workloads from the cloud to on-premises, mostly in the IaaS space. The main reasons companies are re-evaluating public cloud are cost, wanting total control […]

Amazon EC2 Credential Exfiltration: How It Happens and How to Mitigate It

An introduction to Amazon EC2 credentials

When you assign an Identity and Access Management (IAM) role to an Amazon Elastic Compute Cloud (EC2) instance, the short-term credentials for the role are made available via a web service known as the Instance Metadata Service (IMDS). The IMDS provides an HTTP endpoint for retrieving instance metadata such as the instance IP address, AWS Region the instance is running in, the Amazon Machine Image used to launch the instance, and the access key, secret access key, and session token associated with the instance's IAM role. The AWS documentation describes how to retrieve instance role credentials from IMDS. If you've seen or used the http://169.254.169.254 or http://fd00:ec2::254 endpoints, then you've seen/used IMDS.

Retrieval of instance role credentials from IMDS is the mechanism by which the AWS CLI and SDKs learn the credentials belonging to the instance's IAM role without you having to configure anything on the instance. Quoting the IAM documentation:

The AWS SDKs, AWS CLI, and Tools for Windows PowerShell automatically get the credentials from the EC2 Instance Metadata Service (IMDS) and use them.

This is great! It means you can start using the AWS CLI, SDKs, or Tools Continue reading

Create a Samba Share and Use from in a Docker Container

At some point in either your cloud- or container-development life, you’re going to have to share a folder from the Linux server. You may only have to do this in a dev environment, where you want to be able to share files with other developers on a third-party, cloud-hosted instance of Linux. Or maybe file sharing is part of an app or service you are building. And because

Striking a Balance: Exploring Fairness in Buffer Allocation and Packet Scheduling

Recently, I’ve been contemplating the concept of fairness, and I see interesting parallels between being a parent and being a network professional. As human beings, we have an inherent, intuitive sense of fairness that manifests itself in various everyday situations. Let me illustrate this idea with a couple of hypothetical scenarios:

Scenario 1: Imagine I’m a parent with four young children, and I’ve ordered a pizza for them to share. If I want to divide the pizza fairly among the children, fairness would mean that each child receives an equal portion - in this case, one-quarter of the pizza.

Scenario 2: Now let’s say I’ve ordered another pizza for the same four children, but one of the kids only cares for pizza a little and will only eat one-tenth of his share. In this situation, it wouldn’t be fair for me to give that child who doesn’t like pizza more than one-tenth of the piece because the excess would go to waste. The fair way to divide the pizza would be to give the child who doesn’t like pizza a one-tenth portion and split the remaining nine-tenths evenly among the other three kids.

The approach mentioned in the second scenario Continue reading

Cloudflare Radar’s new BGP origin hijack detection system

Cloudflare Radar's new BGP origin hijack detection system
Cloudflare Radar's new BGP origin hijack detection system

Border Gateway Protocol (BGP) is the de facto inter-domain routing protocol used on the Internet. It enables networks and organizations to exchange reachability information for blocks of IP addresses (IP prefixes) among each other, thus allowing routers across the Internet to forward traffic to its destination. BGP was designed with the assumption that networks do not intentionally propagate falsified information, but unfortunately that’s not a valid assumption on today’s Internet.

Malicious actors on the Internet who control BGP routers can perform BGP hijacks by falsely announcing ownership of groups of IP addresses that they do not own, control, or route to. By doing so, an attacker is able to redirect traffic destined for the victim network to itself, and monitor and intercept its traffic. A BGP hijack is much like if someone were to change out all the signs on a stretch of freeway and reroute automobile traffic onto incorrect exits.

Migration Coordinator – Lift and Shift Migration Modes

In the first part of this blog series, takes a high-level view of all the modes that are available with Migration Coordinator, a fully supported tool built into NSX that enables migrating from NSX from vSphere to NSX (NSX-T). The second blog in this series, takes a closer look at the available options for in-place migrations. This third blog in this series, will take  the options available for lift and shift type of migration.

Distributed Firewall

Distributed Firewall mode is one of the first lift and shift modes that was introduced with NSX 3.1 release. This mode allows migrating only the firewall configuration over to NSX running on its own dedicated HW.

Locating the mode: This mode is part of the three advanced migration modes and is found by expanding the “Advanced Migration Modes” highlighted in red below:

NSX Prep:

  1. Installation: NSX manager and Edges. Optionally bridges.
  2. Configuration:
    1. Configure the N/S network connectivity
    2. Create and configure T0s all the way down to the Segments
      1. Segment ID must match the VNI of the NSX for vSphere logical switches
    3. Optionally configure bridges if the migration is expected to take long time and network connectivity between the workloads on NSX for vSphere Continue reading
