Octopus will find a way to reliably deploy your release over even the most complex of network topologies

Complex network topologies

Whether your application servers are behind a firewall, accessible only over a proxy, or connected between a pair of tin cans with string, Octopus can find a way to reliably deploy to them.

Polling or Listening Tentacles

For Windows hosts, Octopus uses an agent called Tentacle. It uses a secure communications protocol, and can be configured in either listening or polling mode. In Listening mode, Tentacles listen on a TCP port (10933 by default) and Octopus contacts it to trigger a deployment. In Polling mode, Tentacle periodically connects to Octopus (on port 10943 by default) to ask if it needs to do anything. This gives you multiple choices for how to best configure your firewall.

Configure around your existing firewall either a listening or polling tentacle

Proxy servers

Sometimes the only way outside the network is via a proxy server. Octopus and Tentacle can be configured to send communications via standard transparent proxies.

Octopus can reliably deploy your release even if there is a proxy server in the way

Bandwidth constrained networks

If production is a long way away from your Octopus server, fear not. Octopus uses delta compression to minimize the size of packages sent over the network, can be throttled to reduce the number of simultaneous operations, and has lots of smarts around timeouts and automatic retries in case the connection is lost. All packages are uploaded ahead of time, so that downtime is minimized as we don't have to wait for package transfers in the middle of a deployment.

Octopus uploads 100 percent of your package ahead of time to ensure downtime is minimised

DMZ's and isolated environments

Some deployment tools assume that your production servers are always on the same Active Directory domain as your deployment server - that's often not the case. The Octopus/Tentacle communication model is based on two-way trust established using X.509 certificates, like a B2B transaction, so you don't have to use hacks like creating users in different domains with the same names and passwords. This approach also makes our communications secure enough to travel directly over the internet.

Kiosks and remote branches

Sometimes you're deploying to remote sites, like kiosks or servers in a branch office or point of sale server systems in a retail environment. Octopus handles machines that sometimes disappear, and can automatically re-deploy to them when they disappear.

Shout out to @OctopusDeploy for making their software so easy to work with. Just upgraded a 2 year out of date instance and migrated it to a new server and it worked with no effort beyond what their documentation said to do.

We've been overhauling our internal infrastructure and back-end systems over the past month, including a move back to full @OctopusDeploy deployments; rediscovering how nice it is to have a platform-agnostic orchestrator that can deploy practically anything, anywhere ❤

Tools like @OctopusDeploy can be great in enabling culture change, we've been able to scale and improve our configuration story since we started using it https://buff.ly/2JyRmTY
