At the inaugural O’Reilly Software Architecture conference, Raffi Krikorian discussed strategies and tactics for technical leads and architects who are undertaking a system rewrite. Drawing on his experience as VP of Twitter Engineering, Krikorian discussed a twelve point plan for managing a re-architecting, including defining “done”, instrumenting existing systems, and enforcing code quality.
Google has recently published a paper providing architectural guidelines for creating a scalable and resilient solution running on their cloud platform. This article digests the respective paper extracting the main ideas and advice. These guidelines can be used with minor changes for deploying web applications on other clouds.
A service is a logical construct owning a business capability and made up of internal autonomous components or microservices that together fulfil the responsibilities of the service, Jeppe Cramon suggests continuing a previous series of blog posts clarifying his view on building services around business capabilities and bounded contexts.
Popular configuration mechanisms like conf.d pose multiple problems when trying to converge system configuration using configuration management tools. Ish-Shalom proposes five design principles for configuration that prevent those problems. The core ideas being the use of a configuration API and the separation of configurations based on the type of system updates they require.

Randy Shoup shared his experiences to the QCon London audience in scaling services at Google and eBay, giving advice on building and operating services. A successful services strategy requires end-to-end service ownership, decentralized decision-making and standardization efforts focused on protocols of communications and supporting infrastructure.
The Yelp engineering team have stated that moving to a service-oriented architecture has allowed them to scale their development process and maintain a rapid pace of software delivery as the team and codebase has grown. This has been achieved by focusing on distributed systems education, creating a set of basic service design principles and implementing a supporting infrastructure.
