Practical Load Balancing starts by introducing key concepts and the tools you''ll need to tackle your load-balancing issues. You''ll travel through the IP layers and learn how they can create increased network traffic for you. You''ll see how to account for persistence and state, and how you can judge the performance of scheduling algorithms.

You''ll then learn how to avoid performance degradation and any risk of the sudden disappearance of a service on a server. If you''re concerned with running your load balancer for an entire network, you''ll find out how to set up your network topography, and condense each topographical variety into recipes that will serve you in different situations. You''ll also learn about individual servers, and load balancers that can perform cookie insertion or improve your SSL throughput. 

You''ll also explore load balancing in the modern context of the cloud. While load balancers need to be configured for high availability once the conditions on the network have been created, modern load balancing has found its way into the cloud, where good balancing is vital for the very functioning of the cloud, and where IPv6 is becoming ever more important.

You can read Practical Load Balancing from end to end or out of sequence, and indeed, if there are individual topics that interest you, you can pick up this book and work through it once you have read the first three chapters.

Next, you''ll take your first steps toward being a Raspberry Pi expert by learning how to get around at the Linux command line. You''ll learn about different shells, including the bash shell, and commands that will make you a true power user.

Finally, you''ll learn how to create your first Raspberry Pi projects:

Need a quick and easy to understand introduction to MongoDB and NoSQL databases? MongoDB Basics, from The Definitive Guide to MongoDB, 2E, shows you how a document-oriented database system differs from a relational database, and how to install and get started using it. You''ll also learn MongoDB design basics, including geospatial indexing, how to navigate, view, and query your database, and how to use GridFS with a bit of Python.

Learn Raspberry Pi 2 with Linux and Windows 10 will tell you everything you need to know about working with Raspberry Pi 2 so you can get started doing amazing things. You''ll learn how to set up your new Raspberry Pi 2 with a monitor, keyboard and mouse, and how to install both Linux and Windows on your new Pi 2.

Linux has always been a great fit for the Pi, but it can be a steep learning curve if you''ve never used it before. With this book, you''ll see how easy it is to install Linux and learn how to work with it, including how to become a Linux command line pro. You''ll learn that what might seem unfamiliar in Linux is actually very familiar. And now that Raspberry Pi also supports Windows 10, a chapter is devoted to setting up Windows 10 for the Internet of Things on a Raspberry Pi.

Finally, you''ll learn how to create these Raspberry Pi projects with Linux:

The Definitive Guide to MongoDB, Third Edition, is updated for MongoDB 3 and includes all of the latest MongoDB features, including the aggregation framework introduced in version 2.2 and hashed indexes in version 2.4. The Third Edition also now includes Python.

MongoDB is the most popular of the "Big Data" NoSQL database technologies, and it''s still growing. David Hows from 10gen, along with experienced MongoDB authors Peter Membrey and Eelco Plugge, provide their expertise and experience in teaching you everything you need to know to become a MongoDB pro.
