Microservices for the Enterprise by Kasun Indrasiri,Prabath Siriwardena Pdf

Understand the key challenges and solutions around building microservices in the enterprise application environment. This book provides a comprehensive understanding of microservices architectural principles and how to use microservices in real-world scenarios. Architectural challenges using microservices with service integration and API management are presented and you learn how to eliminate the use of centralized integration products such as the enterprise service bus (ESB) through the use of composite/integration microservices. Concepts in the book are supported with use cases, and emphasis is put on the reality that most of you are implementing in a “brownfield” environment in which you must implement microservices alongside legacy applications with minimal disruption to your business. Microservices for the Enterprise covers state-of-the-art techniques around microservices messaging, service development and description, service discovery, governance, and data management technologies and guides you through the microservices design process. Also included is the importance of organizing services as core versus atomic, composite versus integration, and API versus edge, and how such organization helps to eliminate the use of a central ESB and expose services through an API gateway. What You'll LearnDesign and develop microservices architectures with confidence Put into practice the most modern techniques around messaging technologies Apply the Service Mesh pattern to overcome inter-service communication challenges Apply battle-tested microservices security patterns to address real-world scenarios Handle API management, decentralized data management, and observability Who This Book Is For Developers and DevOps engineers responsible for implementing applications around a microservices architecture, and architects and analysts who are designing such systems

As sweet as a macaron from Laduree, this romantic novel set in Paris about an American ballerina and a charming French boy is parfait! And don't miss Anne-Sophie's swoony FRENCH KISSING IN NEW YORK! Mia Jenrow has always known she's destined to be a professional ballerina. In fact, it’s in her blood—according to family legend, her too-many-greats-to-count-grandmother once danced for the Paris Opera and was painted by Degas himself! Her parents say it’s just a fantasy, but to Mia it’s so much more than that. It’s her fate. Mia is planning to spend a magical summer in France pursuing her dream, but as she pirou-ettes into Paris, she soon realizes it may be a bit more complicated than she hoped. For starters, there’s her rival, Audrey, who will stop at nothing to show her up. There’s her ballet instructor, whose impossibly high standards push her to the breaking point. And then . . . there’s Louis. Devastatingly, distractingly charming Louis. He’s eager to show Mia his city—and Mia is more than happy to hop on his Vespa and wrap her arms around him as they pass the gleaming lights of the Eiffel Tower. Mia’s summer was supposed to be about ballet—but there’s a reason Paris is called the City of Love. . . .

Taking Flight: From War Orphan to Star Ballerina by Michaela DePrince,Elaine Deprince Pdf

SOON TO BE A MAJOR MOTION PICTURE! The extraordinary memoir of an orphan who danced her way from war-torn Sierra Leone to ballet stardom, most recently appearing in Beyonce’s Lemonade and as a principal in a major American dance company. "Michaela is nothing short of a miracle, born to be a ballerina. For every young brown, yellow, and purple dancer, she is an inspiration!” —Misty Copeland, world-renowned ballet dancer Michaela DePrince was known as girl Number 27 at the orphanage, where she was abandoned at a young age and tormented as a “devil child” for a skin condition that makes her skin appear spotted. But it was at the orphanage that Michaela would find a picture of a beautiful ballerina en pointe that would help change the course of her life. At the age of four, Michaela was adopted by an American family, who encouraged her love of dancing and enrolled her in classes. She went on to study at the Jacqueline Kennedy Onassis School at the American Ballet Theatre and is now the youngest principal dancer with the Dance Theatre of Harlem. She has appeared in the ballet documentary First Position, as well as on Dancing with the Stars, Good Morning America, and Nightline. In this engaging, moving, and unforgettable memoir, Michaela shares her dramatic journey from an orphan in West Africa to becoming one of ballet’s most exciting rising stars. “Michaela DePrince is the embodiment of what it means to fight for your dream.” —Today “Michaela DePrince is a role model for girls on and off stage.” —NYLON

Leanne Benjamin by Leanne Benjamin Pdf

This autobiography by Leanne Benjamin with Sarah Crompton reveals the extraordinary life and career of one of the worlds most important ballet dancers of the past fifty years. The book takes you behind the scenes to find a real understanding of the pleasure and the pain, the demands and the intense commitment it requires to become a ballet dancer. It is a book for ballet-lovers which will explain from Benjamins personal point of view, how ballet has changed and is changing. It is a book of history: she was first taught by the people who created ballet in its modern form and now she works with the dancers of today, handing on all she has known and learnt. But it is also a book for people who are just interested in the psychology of achievement, how you go from being a child in small-town Rockhampton in the centre of Australia to being a power on the worlds biggest stages -- and how an individual copes with the ups and downs of that kind of career. It is a story full of big names and big personalities -- Margot Fonteyn, Kenneth MacMillan, Mikhail Baryshnikov, Darcey Bussell, Carlos Acosta to name a few. President Clinton, Michelle Obama, Diana Princess of Wales and David Beckham all make an appearance. But it is also a book of small moments of insight: what makes a performance special, how you recover from injury, illness and childbirth; how you combine athletic and artistic prowess with motherhood, how a different partner can alter everything, what it is like to fall over in front of thousands of people and what it is like to triumph. Above all, it seeks to explain, in warm and human terms, why women get the reputation for being difficult in a world where being a good girl is too much prized. And what they can do about it.

The Art of Grace: On Moving Well Through Life by Sarah L. Kaufman Pdf

"Sarah Kaufman offers an old-fashioned cure for a modern-day ailment. The remedy for our culture of coarseness is grace…This is an elegant, compelling, and, yes, graceful book." —Daniel H. Pink, author of Drive In this joyful exploration of grace’s many forms, Pulitzer Prize–winning critic Sarah L. Kaufman celebrates a too-often-forgotten philosophy of living that promotes human connection and fulfillment. Drawing on the arts, sports, the humanities, and everyday life—as well as the latest findings in neuroscience and health research—Kaufman illuminates how our bodies and our brains are designed for grace. She promotes a holistic appreciation and practice of grace, as the joining of body, mind, and spirit, and as a way to nurture ourselves and others.
