Dominique Lacan’s Summary

One of the defining characteristics of internet era software is that it is delivered as a service, not as a product.
This fact leads to a number of fundamental changes : Operations must become a core competency. When software is an always-available online service, it is no longer just software development that determines success, it’s operations that day-to-day ongoing management of data and services.
Google’s success is due not just to its patented PageRank search algorithms but how well it builds and runs its data centers.
it must continuously crawl the web and update its indices, continuously filter out link spam and other attempts to influence its results, scale to hundreds of millions of asynchronous user queries, simultaneously matching them with context-appropriate advertisements.

Using horizontal scaling techniques and commodity hardware components for simplified fault-tolerance and high availability
Using low-cost software to leverage large support communities and resources
Ensuring that adequate systems monitoring and management is in place
Ensuring that operations planning and staffing are first-class priorities

At an application level, this means no longer having the development team throwing it over the wall to operations and forgetting about it : they must actively integrate deployment, data management, feedback loops, and metrics.
Dynamic languages (often called scripting languages and looked down on by the software engineers of the era of software artifacts) such as Perl and PHP are the tools of choice for system and network administrators, as well as application developers building dynamic systems that require constant change.
Employ dynamic languages to enable adaptability to change, speed and productivity. Consider development frameworks that focus on simplification and productivity.
