Modern languages like Python, NodeJS, and Go make it easy to handle concurrent requests for multiple customers at the same time by using threads or goroutines. Such services seem very cost effective because one process can handle hundreds or thousands of tenants. However, this efficiency comes at a hidden, steep price. When language runtime scheduling breaks down, one tenant can cause an outage for everyone.
This blog post marks an important milestone for us! Just four years ago, as we grew frustrated with the state of SSH server access, Teleport was born. Eventually it grew way bigger than just SSH access, as our users want to use the same access workflow for all layers of their stacks. And today we’re announcing another way to use Teleport: as a hosted offering. Let’s dig deeper!
OAKLAND, Calif. – Nov. 19, 2020 — Gravitational, a pioneer in environment-free computing, announced today that the company has changed its name to Teleport, effective immediately.
Today, we are announcing the availability of Teleport 5.0. This is a major release for the project with numerous improvements and new features, but the hallmark capability of this version is the Unified Access Plane and Application Access for Developers. For those unfamiliar with Teleport, it is an open source project for giving developers secure remote access to everything they need.
Dear Reader, Today we are officially announcing that Gravitational is becoming Teleport. As part of the transition, we are launching a new website and moving from gravitational.com to https://goteleport.com. But that’s not the most important part. A much more interesting side of the story is why we are doing this and the new product announcements and the direction we are taking.
Cyber threats are a feature of our everyday digital life. Most of us have been the victim of one of these attacks, even if we are unaware. The larger hacks make it into the public consciousness, like Equifax, Ashley Madison, Capital One, and more, but we rarely hear from Silicon Valley tech companies. While not infallible, companies like Twitter or Facebook are still not held to strict standards for customer safety.
About a year ago, a friend of mine decided to build an EVM (Ethereum Virtual Machine) assembler in Rust. After some prodding from him, I began to help by writing unit tests. At the time, I knew very little about operating systems and started to read about lexical and symbolical analyzers. I was quickly in way over my head. What I did retain, however, was a newfound appreciation for the OS as a whole. So, when he started raving about eBPF, I knew I was in for a treat.
In this blog post we’ll cover how to set up an SSH jump server. We’ll cover two open source projects. Both of these servers are easy to install and configure, are free and open-source, and are single-binary Linux daemons. An SSH jump server is a regular Linux server, accessible from the Internet, which is used as a gateway to access other Linux machines on a private network using the SSH protocol.
Teleport 4.4 is here! The major innovation we’re introducing in this version is much improved control over interactive sessions for SSH and Kubernetes protocols. We’ll do a deeper dive into session control later, but for those who aren’t familiar with it, Teleport is an open source project. It provides access to SSH servers and Kubernetes clusters on any infrastructure, on any cloud, or any IoT device, anywhere, even behind NAT.
A SSH session can be interactive or non-interactive. The session starts when a computer or human connects to a node using SSH. SSH sessions can be established using public/private key cryptography or can use short lived SSH Certificates, similar to how Teleport works. Organizations often want to know who is accessing the systems and provide a greater level of control over who and when people are accessing them, which is where Teleport 4.4 comes into play.
