Build your own cloud based Database as a Service using OpenStack Trove
About This Book
- Familiarize yourself with the concept of Database as a Service and make your existing system scalable and efficient with OpenStack Trove
- Minimize the administrative tasks and complexities of managing your cloud infrastructure
- This is a fast-paced guide to datastore management on the OpenStack platform using OpenStack Trove
Who This Book Is For
If you are a DBA / system administrator / architect, or a student who wants to build a Database as a Service based on OpenStack, this book is for you. You should have a basic knowledge of OpenStack components, RDBMS/NoSQL, IaaS, and cloud computing.
What You Will Learn
- Get to grips with the basics of OpenStack and the prerequisites to install Trove
- Understand the expectations of DBaaS and how Trove can help you achieve them
- Set up a basic installation of DevStack (Development Stack) in a virtual box
- Install Trove and utilize its configuration groups to manage and tune databases
- Use Image builder to create guest images for Trove
- Utilize Trove to provision your first database instance
- Back up and restore your databases with the help of Trove
In Detail
OpenStack has become an extremely popular solution to build public and private clouds with. Database as a Service (DBaaS) enables the delivery of more agile database services at lower costs. Some other benefits of DBaaS are secure database deployments and compliance to standards and best practices. Trove is a DBaaS built on OpenStack and is becoming more popular by the day.
Since Trove is one of the most recent projects of OpenStack, DBAs and system administrators can find it difficult to set up and run a DBaaS using OpenStack Trove. This book helps DBAs make that step. We start by introducing you to the concepts of DBaaS and how is it implemented using OpenStack Trove. Following this, we look at implementing OpenStack and deploying Trove. Moving on, you will learn to create guest images to be used with Trove. We then look at how to provision databases in self-service mode, and how to perform administration tasks such as backup and recovery, and fine-tuning databases. At the end of the book, we will examine some advanced features of Trove such as replication.
Style and approach
This fast-paced, step-by-step guide introduces you to DBaaS, OpenStack Trove, and its components, leading you through building your own Cloud-based DBaaS. Using the DevStack deployment method, you will spend less time on installing OpenStack so you can devote more time to learning how to provision and manage databases in a DBaaS environment.

Preface
Database management has come a long way over the last decade or so. The process of provisioning databases used to start with racking and stacking a physical server, installing and configuring an operating system, and finally, installing and configuring a database management system. This entire process took weeks and, in some cases, months. Once the database is provisioned, you then of course have a whole host of things to be managed, including availability, backups, security, and performance. This provisioning and management consumed a lot of time and resources. During the evolution, we had two trends that have had a significant impact on the way databases were provisioned and managed. Automation eased the management aspect and virtualization eased the provisioning, at least up to the operating-system layer. Meanwhile, the other trend that we have seen is that enterprises are moving away from a single database technology model to a model which is fancily termed "polyglot persistence". This basically means adopting multiple database technologies with the intention of storing the data in a database that is best suited for that type of data. With multiple types of database technologies coming into play, enterprises are finding it difficult to manage this complexity while maintaining corporate standards and compliance.
Fortunately for us, over the last couple of years, cloud is the other trend that came to our rescue. With the advent of cloud, we have initially seen self-service based agile provisioning of infrastructure take off, which has been termed as Infrastructure as a Service and has automated a lot of aspects and made infrastructure management easier. Building on this a bit more, we now have self-service based agile provisioning of multiple types of databases, which is popularly known as Database as a Service (DBaaS). This has made things much easier for enterprises in terms of bringing in efficiencies and enforcing corporate standards and compliance. Enterprises can avail DBaaS from a public cloud such as Amazon Web Services or Microsoft Azure. Alternatively, they can build their own private cloud-based DBaaS and the need for this could be owing to various reasons such as data privacy and security. This is where OpenStack and Trove comes into the picture. OpenStack Trove is an open source implementation of DBaaS. While it has been in existence for a couple of years, it has started gaining momentum only recently with enterprises giving it a serious thought.
The benefits of DBaaS in general and OpenStack Trove in particular are obvious. The key challenge, however, is that beyond the documentation that is available from the OpenStack project itself, there is not much reading material out there to help potential DBAs and system/cloud administrators. This lack of skill and know-how is one of the potential inhibitors to OpenStack Trove adoption.
This book is an attempt to provide all the essential information that is necessary to kick-start your learning of OpenStack Trove and set up your own cloud-based DBaaS. In this book, the readers will be introduced to all major components of OpenStack Trove. Following this, the readers will get to understand how to set up Trove in both development and production environments, configuring it, and performing management activities such as backup and restore. Not to mention, it also deals with certain advanced database features, such as replication and clustering. This book takes a more practical approach to learning, as the learning from each chapter will contribute to the reader's ability to build his/her own private cloud-based DBaaS by the time he/she completes reading this book. We hope you will enjoy reading this book and, more importantly, find it useful in your journey towards learning and implementing DBaaS using OpenStack Trove.
