Datanauts 075: AWS Warts And All
The Datanauts and guest Alex Galbraith examine the gotchas of storage, networking, and scaling in AWS so you can get the best design for the least amount of money. The post Datanauts 075: AWS Warts And All appeared first on Packet Pushers.Linux Systemd & Golang Services using Kardianos Service
This week I have done something new, but I found myself dealing with a ‘zero knowledge’ situation or something I like to call ZKS. This is one of those ones where it’s fun, but it also feels a bit stressy as there was enough rope to hang myself with.
That something new is Systemd, which is a Linux operating system thing that manages the initialisation of user things. To speak about this more technically, it is a drop in replacement ‘init’ system that starts services and sets up the user environment. Wikipedia has this to say about it:
Systemd is an init system used in Linux distributions to bootstrap the user space and manage all processes
For those lacking historic knowledge around systemd, it previously many upset devs and administrators, which in turn setup a site called ‘boycottsystemd’ which looks to be offline. They said it flies in the face of doing it the Unix way, which is (to summarise) do one thing and do it well. Systemd is now the default init system for Ubuntu 15x and newer releases. Can’t be that bad…right?
Whilst this is not a complete education around systemd, it’s popular and is reasonably easy to Continue reading

Introducing Zero Round Trip Time Resumption (0-RTT)
Cloudflare’s mission is to help build a faster and more secure Internet. Over the last several years, the Internet Engineering Task Force (IETF) has been working on a new version of TLS, the protocol that powers the secure web. Last September, Cloudflare was the first service provider to enable people to use this new version of the protocol, TLS 1.3, improving security and performance for millions of customers.
Today we are introducing another performance-enhancing feature: zero round trip time resumption, abbreviated as 0-RTT. About 60% of the connections we see are from people who are visiting a site for the first time or revisiting after an extended period of time. TLS 1.3 speeds up these connections significantly. The remaining 40% of connections are from visitors who have recently visited a site and are resuming a previous connection. For these resumed connections, standard TLS 1.3 is safer but no faster than any previous version of TLS. 0-RTT changes this. It dramatically speeds up resumed connections, leading to a faster and smoother web experience for web sites that you visit regularly. This speed boost is especially noticeable on mobile networks.
We’re happy to announce that 0-RTT is Continue reading
Understanding the Federal Government’s Rapid Adoption of Cloud
One of the biggest trends in the IT industry at the moment is enterprise adoption of the public cloud. It’s obvious that it’s been accelerating over the recent years, but perhaps more importantly, Federal agencies are beginning to take a serious look at the cloud in an effort to reform IT and to achieve greater agility …Continue reading "Understanding the Federal Government’s Rapid Adoption of Cloud"
