There is a lot of talk about graphing all the things, but have you ever considered graphing all the people – in particular their on calls – as well? “Not letting people burnout on call is something that is being talked about in the industry,” said Jordan J. Hamel, Design Engineer at the biotech company Amgen.
Today we are very proud and happy to launch our latest non-supported release, CFEngine 3.14.0. 3.14 is a great number, being the closest we will get to PI, we also wanted to introduce something very special this time around, and we did!
This post will describe how to manually build a Ubuntu 18.04 Virtual Machine (VM) server using Oracle’s VirtualBox virtualisation software. Being able to build simple, expendable VMs is extremely useful, whether you’re writing software, building websites or just wanting to learn about Linux servers. We need to be able to SSH onto the server from our host machine to make access easier. To gain SSH access we therefore need to forward SSH’s port to our host.
For years, high-trust organizations relied on Hipchat for team messaging because—unlike many popular messaging platforms—it could be hosted on-premise or in a private cloud. In July 2018, however, they found out that Hipchat would be decommissioned this year. In search of a secure messaging solution to replace Hipchat, many of these companies have migrated to Mattermost, the open source messaging platform designed for DevOps teams.
Cycle aims to give you maximum flexibility with how you architect your application. By marking a container as ‘stateful’, you’re declaring that the container and its instances should be treated more like pets than cattle, but more on that analogy below. The need to maintain state should never be a deciding factor when considering whether or not to containerize as containers are simply portable code packages.
We currently have six major cloud platforms offering serverless products, AWS Lambda being the pioneer. Our goal is to provide a quick way to compare and evaluate all. For each service, we will be evaluating: There are smaller service providers on the market that are focused on serverless, but we won’t cover them in the present analysis. For the pricing comparison, we considered regions in the United States east coast. Let the battle begin!
Lambda Layers were introduced by AWS in late 2018 as a way to simplify the developer’s life when managing dependencies and shared resources across a multi-Lambda stack. It’s a versatile feature that brings many benefits, which we will discuss in this article. Using Lambda Layers does increase complexity to monitor and maintain your applications, but there’s no need to fear.
Kubernetes is a powerful platform that has shifted the way modern software operates and scales over the past five years. It’s got a strong open source community and benefits from innovation from the collective. Also, some of its current shortcomings are: difficulties in installation, complexity, and customization. In many ways, Kubernetes is like the Linux kernel: it provides a framework for running software, but none of the tools. This is where Kubernetes distributions (or distros) come in.
If you’ve dealt with lambda functions you may have run across the RequestEntityTooLargeException - * byte payload is too large for the Event invocation type (limit 131072 bytes) AWS Lambda exception that occurs when a function is invoked with too large of a payload. Current AWS Lambda limits are set at 6 MB for synchronous/RequestResponse invocations, and 128 K for asynchronous/Event invocations.
