As traffic volume and data demands increase, these applications become more complicated and brittle, exposing risks and compromising availability. This practical guide shows IT, devops, and system reliability managers how to prevent an application from becoming slow, inconsistent, or downright unavailable as it grows.Scaling isn't just about handling more users; it's also about managing risk and ensuring availability. Author Lee Atchison provides basic techniques for building applications that can handle huge quantities of traffic, data, and demand without affecting the quality your customers expect.In five parts, this book explores:Availability: learn techniques for building highly available applications, and for tracking and improving availability going forwardRisk management: identify, mitigate, and manage risks in your application, test your recovery/disaster plans, and build out systems that contain fewer risksServices and microservices: understand the value of services for building complicated applications that need to operate at higher scaleScaling applications: assign services to specific teams, label the criticalness of each service, and devise failure scenarios and recovery plansCloud services: understand the structure of cloud-based services, resource allocation, and service distribution

    And this may sound weirdly obvious, but every single one of those pieces of software was written by a programmer. Programmers are thus among the most quietly influential people on the planet. As we live in a world made of software, they're the architects. The decisions they make guide our behavior. When they make something newly easy to do, we do a lot more of it. If they make it hard or impossible to do something, we do less of it.If we want to understand how today's world works, we ought to understand something about coders. Who exactly are the people that are building today's world? What makes them tick? What type of personality is drawn to writing software? And perhaps most interestingly -- what does it do to them?One of the first pieces of coding a newbie learns is the program to make the computer say "Hello, world!" Like that piece of code, Clive Thompson's book is a delightful place to begin to understand this vocation, which is both a profession and a way of life, and which essentially didn't exist little more than a generation ago, but now is considered just about the only safe bet we can make about what the future holds. Thompson takes us close to some of the great coders of our time, and unpacks the surprising history of the field, beginning with the first great coders, who were women. Ironically, if we're going to traffic in stereotypes, women are arguably "naturally" better at coding than men, but they were written out of the history, and shoved out of the seats, for reasons that are illuminating. Now programming is indeed, if not a pure brotopia, at least an awfully homogenous community, which attracts people from a very narrow band of backgrounds and personality types. As Thompson learns, the consequences of that are significant - not least being a fetish for disruption at scale that doesn't leave much time for pondering larger moral issues of collateral damage. At the same time, coding is a marvelous new art form that has improved the world in innumerable ways, and Thompson reckons deeply, as no one before him has, with what great coding in fact looks like, who creates it, and where they come from. To get as close to his subject has he can, he picks up the thread of his own long-abandoned coding practice, and tries his mightiest to up his game, with some surprising results.More and more, any serious engagement with the world demands an engagement with code and its consequences, and to understand code, we must understand coders. In that regard, Clive Thompson's Hello, World! is a marvelous and delightful master class.

    Well, what if you don’t have no people? Or any you know of? What then? Are you doomed?” This is the nagging question of fifteen-year-old Nell’s life. Born with a cleft palate and left a foundling on the doorstep of a convent, she yearns to know her mother, whose name, she knows, was Jane.When the Mother Superior tries to pawn her off to a mean looking farmer and his beaten down wife, Nell opts for the only alternative she can see: she runs away. A chance encounter with a dime novel exhorting the exploits of Calamity Jane, heroine of the west, gives Nell the purpose of her life: to find Calamity Jane, who Nell is convinced is her mother.Her quest takes her down rivers, up rivers and across the Badlands to Deadwood, South Dakota and introduces her to Soot, a big, lovable black dog, and Jeremy Chatterfield, a handsome young Englishman who isn’t particular about how he makes his way, as long as he doesn't have to work for it. Together they trek across the country meeting characters as wonderful and bizarre as the adventure they seek, learning about themselves and the world along the way.

    I would love to write that book, but at this time I have no indication that such a book would be worth writing. Most books fail in the market, and most of them fail not because they are poorly written or edited, but because there aren’t enough people interested in them. They are not the right it.What you are reading now is a pretotype edition of the book. I wrote and “edited” it in days instead of months, just to test the level of interest in such a book. I had a few friends and colleagues review it, but don’t be surprised if you find typos, misspellings, bad grammar, awkward formatting and all sorts of misteaks.Releasing it in its present state is not easy for me.The toughest thing about pretotyping is not developing pretotypes, that’s the fun part. The tough part is getting over our compulsion for prema- ture perfectionism and our desire to add more features, or content, before releasing the first version. The tough part is getting our pretotypes in front of people, where they will be judged, criticized and – possibly – rejected.Reid Hoffman, founder of LinkedIn once said: “If you are not embarrassed by the first version of your product, you’ve launched too late.”I am plenty embarrassed. I must be on the right track.http://www.pretotyping.org/pretotype-...

    Vaughn Vernon couples guided approaches to implementation with modern architectures, highlighting the importance and value of focusing on the business domain while balancing technical considerations.Building on Eric Evans’ seminal book, Domain-Driven Design, the author presents practical DDD techniques through examples from familiar domains. Each principle is backed up by realistic Java examples–all applicable to C# developers–and all content is tied together by a single case study: the delivery of a large-scale Scrum-based SaaS system for a multitenant environment.The author takes you far beyond “DDD-lite” approaches that embrace DDD solely as a technical toolset, and shows you how to fully leverage DDD’s “strategic design patterns” using Bounded Context, Context Maps, and the Ubiquitous Language. Using these techniques and examples, you can reduce time to market and improve quality, as you build software that is more flexible, more scalable, and more tightly aligned to business goals.
