“Dedicated to our be-loved parents and family”
Gone are the days where we had to use our own data centers to create our database infrastructure. We have seen a lot of progress in the cloud computing arena. We can now peacefully deploy our databases or applications on the cloud and avoid the cost and pain of managing the infrastructure. Likewise, most organizations have special projects in place to migrate their proprietary license databases to Open Source databases like PostgreSQL. Most such organizations consider it the right time to migrate to a PostgreSQL database deployed on the cloud, because doing so can save them money and effort. Thus, we knew it was time to write a book that helps users understand the advantages and limitations of all the existing cloud vendors available for deploying PostgreSQL on their platforms.
This book contains the details about the major vendors available to deploy a PostgreSQL database on the cloud. It starts with an introduction to DBaaS and IaaS and a brief description of the criteria considered by organizations when deploying databases as a service. We talk about the major concerns and issues you might come across while deploying databases on the cloud. We included steps and procedures involved in migrating from on-premise to the cloud. As this book is mainly written to address the process of deploying a PostgreSQL database on the cloud, we include a detailed architecture of PostgreSQL in one of the chapters. The architecture of PostgreSQL should help you understand most of the parameters that are needed to better tune your PostgreSQL environment.
The main part of the book is a beginner’s guide to deploying PostgreSQL as a service on Amazon Web Services, Microsoft Azure, the Google cloud platform, and the Rackspace cloud platform. You will read an introduction to the services offered by each of these vendors for PostgreSQL, along with the steps to create your first PostgreSQL instance in a production environment. This book focuses on helping novice PostgreSQL users deploy a production PostgreSQL database as a service on any of these cloud vendors.
The book covers major aspects of this process—such as security, high availability, encryption, replication, monitoring, and connection pooling. All these topics are discussed about every cloud vendor, along with the services each of these vendors offers to satisfy the requirements.
