We'll begin with the AWS fundamentals, and you'll build the foundation for the recipes you'll work on throughout the book. Next, you will find out how to manage multiple accounts and set up consolidated billing. You will then learn to set up reliable and fast hosting for static websites, share data between running instances, and back up your data for compliance. Moving on, you will find out how to use the compute service to enable consistent and fast instance provisioning, and will see how to provision storage volumes and autoscale an application server. Next, you'll discover how to effectively use the networking and database service of AWS. You will also learn about the different management tools of AWS along with securing your AWS cloud. Finally, you will learn to estimate the costs for your cloud. By the end of the book, you will be able to easily administer your AWS cloud. What you will learn ?Discover the best practices to achieve an automated repeatable infrastructure in AWS ?Bring down your IT costs by managing AWS successfully and deliver high availability, fault tolerance, and scalability ?Make any website faster with static and dynamic caching ?Create monitoring and alerting dashboards using CloudWatch ?Migrate a database to AWS ?Set up consolidated billing to achieve simple and effective cost management with accounts ?Host a domain and find out how you can automate health checks About the Author Lucas Chan has been working in tech since 1995 in a variety of development, systems admin, and DevOps roles.

Cassandra is a distributed database that stands out thanks to its robust feature set and intuitive interface, while providing high availability and scalability of a distributed data store. This book will introduce you to the rich feature set offered by Cassandra, and empower you to create and manage a highly scalable, performant and fault-tolerant database layer. The book starts by explaining the new features implemented in Cassandra 3.x and get you set up with Cassandra. Then you'll walk through data modeling in Cassandra and the rich feature set available to design a flexible schema. Next you'll learn to create tables with composite partition keys, collections and user-defined types and get to know different methods to avoid denormalization of data. You will then proceed to create user-defined functions and aggregates in Cassandra. Then, you will set up a multi node cluster and see how the dynamics of Cassandra change with it. Finally, you will implement some application-level optimizations using a Java client. By the end of this book, you'll be fully equipped to build powerful, scalable Cassandra database layers for your applications. What you will learn ?Install Cassandra ?Create keyspaces and tables with multiple clustering columns to organize related data ?Use secondary indexes and materialized views to avoid denormalization of data
