A practical guide for developing end-to-end serverless
microservices in Python for developers, DevOps, and architects. Key
Features Create a secure, cost-effective, and scalable serverless
data API Use identity management and authentication for a
user-specific and secure web application Go beyond traditional web
hosting to explore the full range of cloud hosting options Book
DescriptionOver the last few years, there has been a massive shift
from monolithic architecture to microservices, thanks to their
small and independent deployments that allow increased flexibility
and agile delivery. Traditionally, virtual machines and containers
were the principal mediums for deploying microservices, but they
involved a lot of operational effort, configuration, and
maintenance. More recently, serverless computing has gained
popularity due to its built-in autoscaling abilities, reduced
operational costs, and increased productivity. Building Serverless
Microservices in Python begins by introducing you to serverless
microservice structures. You will then learn how to create your
first serverless data API and test your microservice. Moving on,
you'll delve into data management and work with serverless
patterns. Finally, the book introduces you to the importance of
securing microservices. By the end of the book, you will have
gained the skills you need to combine microservices with serverless
computing, making their deployment much easier thanks to the cloud
provider managing the servers and capacity planning. What you will
learn Discover what microservices offer above and beyond other
architectures Create a serverless application with AWS Gain secure
access to data and resources Run tests on your configuration and
code Create a highly available serverless microservice data API
Build, deploy, and run your serverless configuration and code Who
this book is forIf you are a developer with basic knowledge of
Python and want to learn how to build, test, deploy, and secure
microservices, then this book is for you. No prior knowledge of
building microservices is required.
Understand Gang of Four, architectural, functional, and reactive
design patterns and how to implement them on modern Java platforms,
such as Java 12 and beyond Key Features Learn OOP, functional, and
reactive patterns for creating readable and maintainable code
Explore architectural patterns and practices for building scalable
and reliable applications Tackle all kinds of performance-related
issues and streamline development using design patterns Book
DescriptionJava design patterns are reusable and proven solutions
to software design problems. This book covers over 60 battle-tested
design patterns used by developers to create functional, reusable,
and flexible software. Hands-On Design Patterns with Java starts
with an introduction to the Unified Modeling Language (UML), and
delves into class and object diagrams with the help of detailed
examples. You'll study concepts and approaches to object-oriented
programming (OOP) and OOP design patterns to build robust
applications. As you advance, you'll explore the categories of GOF
design patterns, such as behavioral, creational, and structural,
that help you improve code readability and enable large-scale reuse
of software. You'll also discover how to work effectively with
microservices and serverless architectures by using cloud design
patterns, each of which is thoroughly explained and accompanied by
real-world programming solutions. By the end of the book, you'll be
able to speed up your software development process using the right
design patterns, and you'll be comfortable working on scalable and
maintainable projects of any size. What you will learn Understand
the significance of design patterns for software engineering
Visualize software design with UML diagrams Strengthen your
understanding of OOP to create reusable software systems Discover
GOF design patterns to develop scalable applications Examine
programming challenges and the design patterns that solve them
Explore architectural patterns for microservices and cloud
development Who this book is forIf you are a developer who wants to
learn how to write clear, concise, and effective code for building
production-ready applications, this book is for you. Familiarity
with the fundamentals of Java is assumed.
Grasp advanced PowerShell Core 6.0 functionalities to automate your
environment Key Features Keep up with changes introduced in
PowerShell Core 6.0 Easily maintain appropriate compatibility with
older versions Automate complex tasks, manipulate data, and secure
your environment with PowerShell Core 6.0 Book
DescriptionPowerShell scripts offer a handy way to automate various
chores, however working effectively with these scripts can be a
difficult task. This comprehensive guide starts with the
fundamentals before moving on to advanced-level topics to help you
become a PowerShell Core 6.0 expert. The first module, PowerShell
Core 6.0 Fundamentals, begins with the new features of PowerShell
Core 6.0, installing it on Linux, and working with parameters,
objects and .NET classes from within PowerShell Core 6.0. As you
make your way through the chapters, you'll see how to efficiently
manage large amounts of data and interact with other services using
PowerShell Core 6.0. You'll be able to make the most of PowerShell
Core 6.0's powerful automation feature, where you will have
different methods available to parse data and manipulate regular
expressions and Windows Management Instrumentation (WMI). After
having explored automation, you will enter the extending PowerShell
Core 6.0 module, covering asynchronous processing and desired state
configuration. In the last module, you will learn to extend
PowerShell Core 6.0 using advanced scripts and filters, and also
debug issues along with working on error handling techniques. By
the end of this book, you will be an expert in scripting with
PowerShell Core 6.0. What you will learn Optimize code through the
use of functions, switches, and looping structures Work with
objects and operators to test and manipulate data Parse and
manipulate different data types Create scripts and functions using
PowerShell Use jobs, events, and popular public modules which
assist with implementing multithreading Write .NET classes with
ease within the PowerShell Create and implement regular expressions
in PowerShell scripts Make use of advanced techniques to define and
restrict the behavior of parameters Who this book is forIf you are
a system administrator who wants to become an expert in controlling
and automating your Windows environment, then Mastering Windows
PowerShell Scripting is for you. It is also ideal for those new to
the PowerShell language.
Learn the complete Qt ecosystem and its tools and build UIs for
mobile and desktop applications Key Features Unleash the power of
the latest Qt 5.9 with C++14 Easily compile, run, and debug your
applications from the powerful Qt Creator IDE Build multi-platform
projects that target Android, iOS, Windows, MacOS, Linux, and more
