Effortless Cloud-Native App Development Using Skaffold. Simplify the development and deployment of cloud-native Spring Boot applications on Kubernetes with Skaffold

Ashish Choudhary

Kubernetes has become the de facto standard for container orchestration, drastically improving how we deploy and manage cloud-native apps. Although it has simplified the lives of support professionals, we cannot say the same for developers who need to be equipped with better tools to increase productivity. An automated workflow that solves a wide variety of problems that every developer faces can make all the difference!Enter Skaffold – a command-line tool that automates the build, push, and deploy steps for Kubernetes applications.This book is divided into three parts, starting with common challenges encountered by developers in building apps with Kubernetes. The second part covers Skaffold features, its architecture, supported container image builders, and more. In the last part, you'll focus on practical implementation, learning how to deploy Spring Boot apps to cloud platforms such as Google Cloud Platform (GCP) using Skaffold. You'll also create CI/CD pipelines for your cloud-native apps with Skaffold. Although the examples covered in this book are written in Java and Spring Boot, the techniques can be applied to apps built using other technologies too.By the end of this Skaffold book, you'll develop skills that will help accelerate your inner development loop and be able to build and deploy your apps to the Kubernetes cluster with Skaffold.

EJB 3.0 Database Persistence with Oracle Fusion Middleware 11g. This book walks you through the practical usage of EJB 3.0 database persistence with Oracle Fusion Middleware. Lots of examples and a step-by-step approach make it a great way for EJB application developers to acquire new skills

Deepak Vohra

EJB (Enterprise JavaBeans) 3.0 is a commonly used database persistence technology in Java EE applications. EJB 3.0 has simplified the development of EJBs with an annotations-based API that eliminates the use of remote/local interfaces, home/local home interfaces, and deployment descriptors. A number of other books are available on EJB 3.0, but none covers EJB 3.0 support in Oracle Fusion Middleware 11g, which is one of the leaders in the application server market.This is the first book that covers all aspects of EJB 3.0 database persistence development using Oracle Fusion Middleware technology. It covers all the best practices for database persistence ensuring that your applications are easily maintainable. Leaving theory behind, this book uses real-world examples to guide you in building your own EJB 3.0 applications that are well integrated with commonly used Java EE frameworks.The book gets going by discussing the new features in the EJB 3.0 specification. As some readers may still be using EJB 2.0, the book explains how to convert your EJB 2.0 entity beans to EJB 3.0. It then goes on to discuss using EJB 3.0 database persistence with JDeveloper, WebLogic Server, and Enterprise Pack for Eclipse, the main Java EE components of Oracle Fusion Middleware 11g. The book also covers EJB 3.0 relationships and integrating EJB 3.0 relationships with JSF user interfaces. EJB 3.0 database persistence with some of the commonly used frameworks such as ADF Faces, AJAX, and Web Services is also discussed in the book. It uses the integrated WebLogic Server 11g in some of the chapters and the standalone WebLogic Server in other chapters. While JDeveloper is the primary Java IDE used in the book, one of the chapters is based on the Oracle Enterprise Pack for Eclipse.By the time you reach the end of this book, you will be well-versed with developing EJB 3.0 applications using the different Java EE components of Oracle Fusion Middleware 11g.

E-konsument w Europie - komparatywna analiza zachowań

Magdalena Jaciow, Agata Stolecka - Makowska, Robert...

Kraje Europy rozwijają się w różnym tempie, stopniu i zakresie, w zależności od czynników ekonomicznych, demograficznych, społecznych, kulturowych czy stopnia zaawansowania technologicznego. Innowacyjność gospodarki ma coraz większe znaczenie dla rozwoju danego państwa, ponieważ przekłada się na konkurencyjność podmiotów rynkowych i zwyczaje konsumentów. Jednym z przejawów tej innowacyjności jest wirtualizacja życia społeczno-gospodarczego, o określonych skutkach dla handlu międzynarodowego. Książka uzupełnia wiedzę w zakresie zachowań e-konsumentów w Europie. Autorzy skupiają się przede wszystkim na identyfikacji i porównaniu zachowań nabywczych e-klientów w wybranych krajach (we Francji i Włoszech, w Polsce, Portugalii, Rumunii i na Słowacji). Zawarto w niej także informacje, które mogą pomóc w podejmowaniu decyzji przedsiębiorstwom prowadzącym działalność w Internecie i kierującym ofertę do e-konsumentów na obszarze naszego kontynentu. Książka stanowi swoiste kompendium wiedzy na temat zachowań e-konsumentów w Europie, pozwala zidentyfikować ich profil demograficzno-psychograficzny oraz wskazać, jak zachowują się dokonując zakupów w Internecie. To powoduje, że jest ona rzetelnym źródłem wiedzy w zakresie zachowań nabywczych młodych e-konsumentów a przez to może stanowić inspirację dla pracowników naukowych czy studentów prowadzących badania o takiej lub zbliżonej tematyce. prof. US dr hab. EDYTA RUDAWSKA, Uniwersytet Szczeciński (fragment recenzji książki) Analizy dokonane przez autorów pozwalają czytelnikowi zaktualizować swoją wiedzę na temat nowych wyzwań i możliwości, jakie stwarzają globalizacja i technologie internetowe. Styl pisania i struktura książki - mimo iż mamy do czynienia z pracą naukową - są przyjazne czytelnikowi. Książkę czyta się przyjemnie. Jest ona zarówno podręcznikiem, jak i „przewodnikiem” po zagadnieniach marketingu międzynarodowego i międzynarodowych badań rynku. Gorąco polecam. doc. Ing.
