The Storage Networking Industry Association has created a technical work group to address the need for a cloud storage standard. The new Cloud Data Management Interface (CDMI) enables interoperable cloud storage and data management. In CDMI, the underlying storage space exposed by the interfaces is abstracted using the notion of a container. A container is not only a useful abstraction for storage space, but also serves as a grouping of the data stored in it and a point of control for applying data services in the aggregate.

Basic terms and operations of Amazon S3 Description Fundamental entity stored in S3. Each object can range in size from 1 byte to 5 GB. Each object has object data and metadata. Metadata is a set of name-value pairs that describe the data. Fundamental container in S3 for data storage. Objects are uploaded into buckets. There is no limit to the number of objects you can store in a bucket. The bucket provides a unique namespace for the management of objects contained in the bucket. Bucket names are global, so each developer can own only up to 100 buckets at a time. A key is the unique identifier for an object within a bucket. A bucket name plus a key uniquely identifies an object within all of S3. 1. Create a bucket in which to store your data. 2. Upload (write) data (objects) into the bucket. 3. Download (read) the data stored in the bucket. 4. Delete some data stored in the bucket. 5. List the objects in the bucket.

In many cases, the coarse granularity and unstructured nature of cloud storage services such as S3 aren t sufficient for the type of data access required. For many applications, an alternative structured data-storage method is required. Let s explore how databases in the cloud work (and don t).

Your car s navigation system provides constant updates about your current location and destination during your journey. It guides you through the route you need to take. This data, although critical for the trip, isn t useful afterward. The navigation system is to the car what a cloud database is to an application running in the cloud: it s transactional data created and used during the running of that application. When we think of transactional data stored in databases, we usually think of relational databases. What is a Relational Database Management System (RDBMS) Why do we frequently hear that they don t work in the cloud An RDBMS is a database management system in which you store data in the form of tables; the relationship among the data is also stored in the form of tables. You can see this in the simple relation in figure 2.4. A database management system (DBMS) based on the relational model. Relational describes a broad class of database systems that at a minimum present the data to the user as relations (a presentation in tabular form that is, as a collection of tables with each table consisting of a set of rows and columns can satisfy this property) and provide relational operators to manipulate the data in tabular form. All modern commercial relational databases employ SQL as their query language, leading to a shorthand for RDBMSs as SQL databases.
RDBMS
The technological underpinnings of cloud computing
Figure 2.4 A simple example of how a relational database works. Four tables map out relationships among the data. Because a separate table lists the car manufacturers and colors, there is no need to separately list a red Nissan and a blue Nissan. But to fully understand what the car with CarKey 1 is, you must do a join of the Car, Color, MakeModel, and Make tables.
The challenge for an RDBMS in the cloud is scaling. Applications having a fixed number of users and workload requiring an RDBMS won t have any problems. Most cloud providers have an RDBMS offering for these cases. But when applications are launched in environments that have massive workloads, such as web services, their scalability requirements can change quickly and grow large. The first scenario can be difficult to manage if you have a relational database sitting on a single in-house server. For example, if your load triples overnight, how quickly can you upgrade your hardware The second scenario can be too difficult to manage with a relational database, because it becomes a bottleneck choking the application s ability to scale. We ll cover solutions to this in depth in chapter 5. As you ve already learned, one of the core benefits of the cloud is the ability to quickly (or automatically, as we ll show) add more servers to an application as its load increases, thereby scaling it to heavier workloads. But it s hard to expand an RDBMS this way. You have to either replicate data across the new servers or partition between them. In either case, adding a machine requires data to be copied or moved to the new server. This data shipping is a time-consuming and expensive process, so databases are unable to be dynamically and efficiently provisioned on demand. A big challenge with RDBMS partitioning or replicating is maintaining referential integrity. Referential integrity requires that every value of one attribute (column) of a relation (table) exist as a value of another attribute in a different (or the same) relation
