How to Achieve a Resilient Architecture
To manage systems at scale you must push your system almost to the breaking point, but still be able to recover – and embrace failures, Adrian Hornsby writes in two blog posts sharing his experiences from working with large-scale systems for more than a decade, and the patterns he has found useful.

Running a Presidential Campaign with Immutable Infrastructure: Michael Fisher at QCon NY
At QCon New York 2017 Michael Fisher presented “Presidential Campaigns & Immutable Infrastructure” and discussed the implementation and challenges of provisioning infrastructure for the Hillary for America (HFA) campaign that ran during the 2015-2016 US regional and national elections.

Design for Continuous Evolution: Immutable Model Is Key for Robustness
At QCon New York, Eric Brewer described how advancing from continuous delivery to fast and stable continuous evolution requires a discrete construction step to define an immutable model of the system. Brewer’s compute infrastructure design team uses Helm to construct and safely validate new deployment models, prior to attempting real deployment, although the concepts are technology agnostic.

Q&A with Baruch Sadogursky on the Challenges of Managing Docker Containers Lifecycle
InfoQ interviewed Baruch Sadogursky, developer advocate at JFrog, to better understand some of the challenges in managing the lifecycle of Docker containers, namely controlling and tracking the flow of Docker images from development to production.

Bootable Apps for Immutable Infrastructure and Security
Axel Fontaine on the "Bootable App" pattern, a bare bones machine image for deploying immutable infrastructure to the cloud. This minimal image covers all layers of the stack, including OS kernel, libraries and runtime environment but still has a small footprint, reducing both image upload time and storage costs while also significantly reducing the attack surface on running instances.

Disposable Microservices
James Governor from RedMonk has written about how immutable infrastructure approaches are applicable to microservices. In his view, all microservices must be immutable and developers will observe the same benefits which others are already seeing in lower layers of the software stack.

Lessons on Building Continuous Delivery for Infrastructure
Lindsay Holmwood, Flapjack's creator, offers advice to enable fast, with quality, feedback loops and to support small, discrete changes. Holmwood asserts that to get quality feedback there are five main issues to think about: the CAP theorem; SLA definition; SLA validation; interfaces between services; data and infrastructure immutability.

Atlas Workflow and Vagrant Push
Atlas is a new product from Hashicorp, whose main goal is to unify the workflow of moving applications from development to production, by leveraging the suite of open source tools that Hashicorp's been releasing over the years. These include Vagrant, Packer, Terraform and Consul. Atlas rests on the immutable infrastructure principle, meaning you deploy to production entire machine images.

How Immutable State Helped Facebook to Improve Its iOS App Architecture
Facebook has been working in the last two years to evolve the architecture of its iOS app with the goal of improving performance, abstractions, and the underlying development model. Adam Ernst and Arl Grant, software engineers at Facebook, explained what issues they had to solve and how they did in a @Scale 2014 talk.

FutureOps with Immutable Infrastructures and Built-in Failure Recovery
Mitchell Hashimoto, creator of Vagrant, gave a talk last month at Velocity Conf London about his vision for a “FutureOps” with immutable infrastructures and built-in failure recovery.
