Most applications these days are at least somewhat network aware, but how do you protect those applications against common network security threats? Many developers are turning to OpenSSL, an open source version of SSL/TLS, which is the most widely used protocol for secure network communications.The OpenSSL library is seeing widespread adoption for web sites that require cryptographic functions to protect a broad range of sensitive information, such as credit card numbers and other financial transactions. The library is the only free, full-featured SSL implementation for C and C++, and it can be used programmatically or from the command line to secure most TCP-based network protocols.Network Security with OpenSSL enables developers to use this protocol much more effectively. Traditionally, getting something simple done in OpenSSL could easily take weeks. This concise book gives you the guidance you need to avoid pitfalls, while allowing you to take advantage of the library?s advanced features. And, instead of bogging you down in the technical details of how SSL works under the hood, this book provides only the information that is necessary to use OpenSSL safely and effectively. In step-by-step fashion, the book details the challenges in securing network communications, and shows you how to use OpenSSL tools to best meet those challenges.As a system or network administrator, you will benefit from the thorough treatment of the OpenSSL command-line interface, as well as from step-by-step directions for obtaining certificates and setting up your own certification authority. As a developer, you will further benefit from the in-depth discussions and examples of how to use OpenSSL in your own programs. Although OpenSSL is written in C, information on how to use OpenSSL with Perl, Python and PHP is also included.OpenSSL may well answer your need to protect sensitive data. If that?s the case, Network Security with OpenSSL is the only guide available on the subject.
This book on Kubernetes, the container cluster manager, discusses all aspects of using Kubernetes in todays complex big data and enterprise applications, including Docker containers. Starting with installing Kubernetes on a single node, the book introduces Kubernetes with a simple Hello example and discusses using environment variables in Kubernetes. Next, the book discusses using Kubernetes with all major groups of technologies such as relational databases, NoSQL databases, and in the Apache Hadoop ecosystem. The book concludes with using multi container Pods and installing Kubernetes on a multi node cluster. No other book on using Kubernetes - beyond simple introduction - is available in the market. What You Will Learn How to install Kubernetes on a single node How to install Kubernetes on a multi-node cluster How to set environment variables How to create a multi-container pods using Docker How to use volumes How to use Kubernetes with Apache Hadoop Ecosystem How to use Kubernetes with NoSQL Databases How to use Kubernetes with RDBMS Who This Book Is For Application Developers including Apache Hadoop Developers, Database developers and NoSQL Developers.

Based on the latest version of the language, this book offers a self-contained, concise and coherent introduction to programming with Python. The books primary focus is on realistic case study applications of Python. Each practical example is accompanied by a brief explanation of the problem-terminology and concepts, followed by necessary program development in Python using its constructs, and simulated testing. Given the open and participatory nature of development, Python has a variety of incorporated data structures, which has made it difficult to present it in a coherent manner. Further, some advanced concepts (super, yield, generator, decorator, etc.) are not easy to explain. The book specially addresses these challenges; starting with a minimal subset of the core, it offers users a step-by-step guide to achieving proficiency. Dr. T. R. Padmanabhan was formerly Professor Emeritus at Amrita Vishwa Vidyapeetham, Coimbatore. He taught at the IIT Kharagpur, before doing R & D for private companies for several years. He is a Senior Member of the IEEE and a Fellow of both the Institution of Engineers (IEI) and the Institution of Electronics and Telecommunication Engineers (IETE). He has previously published books with Wiley, Tata McGraw-Hill, and Springer Verlag.
Learn how Roslyns new code generation capability will let you write software that is more concise, runs faster, and is easier to maintain. You will learn from real-world business applications to create better software by letting the computer write its own code based on your business logic already defined in lookup tables. Code Generation with Rosyln is the first book to cover this new capability. You will learn how these techniques can be used to simplify systems integration so that if one system already defines business logic through lookup tables, you can integrate a new system and share business logic by allowing the new system to write its own business logic based on already existing table-based business logic. One of the many benefits you will discover is that Roslyn uses an innovative approach to compiler design, opening up the inner workings of the compiler process. You will learn how to see the syntax tree that Roslyn is building as it compiles your code. Additionally, you will learn to feed it your own syntax tree that you create on the fly. What You Will Learn: • Structure logic to be stored in database design • Build complex conditional logic based on lookup data in the database • Compile code that you generate programmatically • Discover generated code and run it dynamically to implement new business logic • Debug problems in generated code • Deploy and access generated code Who This Book Is For: Back end developers in very dynamic fast-paced business environments. Developers focused on integrating different systems across an enterprise should also find this information useful. di Nick Harrison is a Software Architect and .NET advocate in Columbia, SC.
