amr The Practical Challenges of Managing Big Data in the Cloud

Over the past few decades, database and distributed systems researchers have made significant advances in the development of protocols and techniques to provide data management solutions that carefully balance three major requirements when dealing with critical data: high availability, fault-tolerance, and data consistency. However, in recent years, data requirements have been unprecedented, especially in terms of data availability and system scalability for Internet scale enterprises that provide services and cater to millions of users. Cloud computing has emerged as an extremely successful paradigm for deploying Internet and Web-based applications. Scalability, elasticity, pay-per-use pricing, and autonomic control of large-scale operations are the major reasons for the successful widespread adoption of cloud infrastructures. In this lecture, we will analyze the design choices that allowed modern NoSQL data management systems (key-value stores) to achieve orders of magnitude higher levels of scalability compared to traditional databases. Although key-value stores provide high availability, they are not ideal for applications that require consistent data. More recently, there has been a gradual shift to provide transactions with strong consistency. We will analyze the need and the revival of consistent database management systems in large cloud settings. We discuss several state of the art Cloud based data management systems, which provide transactional guarantees on collections of data items, while attempting to ensure efficiency and scalability. Of particular interest are applications which require geo-replicated data management for fault-tolerance. We will therefore explore the data management design space for geo-replicated data and discuss different approaches for replicating data in multi-datacenter environments.
