Docker book designed for SysAdmins, SREs, Operations staff, Developers and DevOps who are interested in deploying the open source container service Docker.
In this book, we'll walk you through installing, deploying, managing, and extending Docker. We're going to do that by first introducing you to the basics of Docker and its components. Then we'll start to use Docker to build containers and services to perform a variety of tasks.
We're going to take you through the development lifecycle, from testing to production, and see where Docker fits in and how it can make your life easier. We'll make use of Docker to build test environments for new projects, demonstrate how to integrate Docker with continuous integration workflow, and then how to build application services and platforms. Finally, we'll show you how to use Docker's API and how to extend Docker yourself.
We'll teach you how to:
* Install Docker.
* Take your first steps with a Docker container.
* Build Docker images.
* Manage and share Docker images.
* Run and manage more complex Docker containers.
* Deploy Docker containers as part of your testing pipeline.
* Build multi-container applications and environments.
* Learn about orchestration using Compose and Swarm for the orchestration of Docker containers and Consul for service discovery.
* Explore the Docker API.
* Getting Help and Extending Docker.
This book is for intermediate to advanced database administrators and developers who use or plan to exploit the features of PostgreSQL in the best possible manner. While administrators can benefit from the topics related to the installation, configuration, and optimization of the server, developers will learn how to write optimal queries and address performance issues in their database design. This book will also benefit the PostgreSQL internal architects in being able to monitor the performance using benchmarking tools.What You Will LearnLearn the best practices to configure your PostgreSQL 9.6 database for optimal performanceWrite optimal queries and techniques to detect performance issue in queriesFine tune the performance of your queries using benchmarking and indexing techniquesEnsure high performance and a highly available database using the scaling and replication techniquesDiscover how to make informed speed and reliability trade-offsHandle increasing database workloads without any hassleUse monitoring insights to continuously rework the design and configuration for best performanceIn Detail
Database administrators and developers spend years learning techniques to configure their PostgreSQL database servers for optimal performance, mostly when they encounter performance issues. Scalability and high availability of the database solution is equally important these days. This book will show you how to configure new database installations and optimize existing database server installations using PostgreSQL 9.6.
You will start with the basic concepts of database performance, because all successful database applications are destined to eventually run into issues when scaling up their performance. You will not only learn to optimize your database and queries for optimal performance, but also detect the real performance bottlenecks using PostgreSQL tools and some external tools. Next, you will learn how to benchmark your hardware and tune your operating system. Optimize your queries against the database with the help of right indexes, and monitor every layer, ranging from hardware to queries. Moving on, you will see how connection pooling, caching, partitioning, and replication will help you handle increasing database workloads.
Achieving high database performance is not easy, but you can learn it by using the right guide—PostgreSQL 9.6 High Performance.Style and approach
This book has been organized in such a manner that will help you understand basic PostgreSQL 9.6 performance tuning to advanced-level configuration. There are many real-world problems explained in this book and explained in clear language, because improving database performance requires an equal mix of understanding theoretical concepts and working through hands-on examples.
Many experienced programmers try to bend Python to fit patterns they learned from other languages, and never discover Python features outside of their experience. With this book, those Python programmers will thoroughly learn how to become proficient in Python 3.
This book covers:Python data model: understand how special methods are the key to the consistent behavior of objectsData structures: take full advantage of built-in types, and understand the text vs bytes duality in the Unicode ageFunctions as objects: view Python functions as first-class objects, and understand how this affects popular design patternsObject-oriented idioms: build classes by learning about references, mutability, interfaces, operator overloading, and multiple inheritanceControl flow: leverage context managers, generators, coroutines, and concurrency with the concurrent.futures and asyncio packagesMetaprogramming: understand how properties, attribute descriptors, class decorators, and metaclasses work
What we need is a systematic process for quickly vetting product ideas and raising our odds of success. That’s the promise of Running Lean.
In this inspiring book, Ash Maurya takes you through an exacting strategy for achieving a "product/market fit" for your fledgling venture, based on his own experience in building a wide array of products from high-tech to no-tech. Throughout, he builds on the ideas and concepts of several innovative methodologies, including the Lean Startup, Customer Development, and bootstrapping.
Running Lean is an ideal tool for business managers, CEOs, small business owners, developers and programmers, and anyone who’s interested in starting a business project.Find a problem worth solving, then define a solutionEngage your customers throughout the development cycleContinually test your product with smaller, faster iterationsBuild a feature, measure customer response, and verify/refute the ideaKnow when to "pivot" by changing your plan’s courseMaximize your efforts for speed, learning, and focusLearn the ideal time to raise your "big round" of fundingGet on track with The Lean Series
