A web application involves many specialists, but it takes people in web ops to ensure that everything works together throughout an application's lifetime. It's the expertise you need when your start-up gets an unexpected spike in web traffic, or when a new feature causes your mature application to fail. In this collection of essays and interviews, web veterans such as Theo Schlossnagle, Baron Schwartz, and Alistair Croll offer insights into this evolving field. You'll learn stories from the trenches--from builders of some of the biggest sites on the Web--on what's necessary to help a site thrive.

• Learn the skills needed in web operations, and why they're gained through experience rather than schooling
• Understand why it's important to gather metrics from both your application and infrastructure
• Consider common approaches to database architectures and the pitfalls that come with increasing scale
• Learn how to handle the human side of outages and degradations
• Find out how one company avoided disaster after a huge traffic deluge
• Discover what went wrong after a problem occurs, and how to prevent it from happening again

How does MongoDB help you manage a huMONGOus amount of data collected through your web application? With this authoritative introduction, you'll learn the many advantages of using document-oriented databases, and discover why MongoDB is a reliable, high-performance system that allows for almost infinite horizontal scalability.

Written by engineers from 10gen, the company that develops and supports this open source database, MongoDB: The Definitive Guide provides guidance for database developers, advanced configuration for system administrators, and an overview of the concepts and use cases for other people on your project. Learn how easy it is to handle data as self-contained JSON-style documents, rather than as records in a relational database.

• Explore ways that document-oriented storage will work for your project
• Learn how MongoDB’s schema-free data model handles documents, collections, and multiple databases
• Execute basic write operations, and create complex queries to find data with any criteria
• Use indexes, aggregation tools, and other advanced query techniques
• Learn about monitoring, security and authentication, backup and repair, and more
• Set up master-slave and automatic failover replication in MongoDB
• Use sharding to scale MongoDB horizontally, and learn how it impacts applications
• Get example applications written in Java, PHP, Python, and Ruby

Create a MongoDB cluster that will grow to meet the needs of your application. With this short and concise book, you'll get guidelines for setting up and using clusters to store a large volume of data, and learn how to access the data efficiently. In the process, you'll understand how to make your application work with a distributed database system.

Scaling MongoDB will help you:
