On Bastion Hosts

I was at a meetup the other night and a student mentioned that they were learning about bastion hosts and wanted to learn more. So I thought I would do a deep dive on what they are and why to use them. What Bastion hosts are instances that sit within your public subnet and are typically accessed using SSH or RDP. Once remote connectivity has been established with the bastion host, it then acts as a ‘jump’ server, allowing you to use SSH or RDP to log in to other instances. »

Future of Reliability Engineering (Part 2)

In early May, I gave a presentation on the ‘Future of Reliability Engineering’. I wanted to break down the five new trends that I see emerging in a blog-post series: Blog Post Series: Evolution of the Network Engineer Failure is the new Normal (move towards Chaos-Engineering) Automation as a Service Cloud is King Observe & Measure Failure is the new Normal (move towards Chaos-Engineering) a) Breaking down Silo’s »

Future of Reliability Engineering (Part 1)

Last month at Interop ITX, I gave a presentation on the ‘Future of Reliability Engineering’. I wanted to break down the five new trends that I see emerging in a blog-post series: Evolution of the Network Engineer (towards Network Reliability Engineers) a) Breaking down Silo’s The network is no longer a silo. Applications run over the network in a distributed fashion requiring low-latency and large data-pipes. With these requirements, network engineers must understand these requirements, understand how applications are generally deployed for troubleshooting purposes and ensure that they have models to plan for capacity management. »
