Storage is another fundamental core IT infrastructure component that is found in both on-prem and cloud datacenters. In this post we will learn the fundamental concepts and basics of Storage infrastructure. We will explore common storage devices and systems and how they are attached and are accessed both in the cloud and local datacenters.

In the previous posts we learned the basics and fundamental concepts of Cloud Computing and Virtualization. In this post we will learn the below topics about Storage infrastructure – a core component in Cloud Computing.

Introduction to Cloud Object Storage

Cloud object storage is commonly found in cloud storage services and offerings and is different from the common file storage technologies such as file and block modes. This type of storage is commonly used in Big data applications in the cloud datacenters.

Data (such as a common file) is paired with metadata and combined into a storage object. Instead of the hierarchical structures found in traditional block and file storage systems, objects are stored in a flat file. With the pool of objects, they are called by their object IDs.

Object ID

An object ID is a the unique identifier of the object globally which points to the stored piece of data. Object storage does not use block or file based storage techniques for locating the data. It uses the object ID to locate the data or metadata in the filesystem of the cloud storage arrays.

Metadata

Metadata is a part of a file or sector header in a storage system that is used to identify the content of the data. It is used in big data applications to index and search for data inside the file. Metadata can consist of many different types of information, such as the type of data or application and the security level. Object storage allows the administrators to define any type of information in metadata and associate it with a file.

Policies

In object storage, policies defines the rights to perform operations such as archive, backup, security, creation, and deletion of storage objects.

Replicas

Replicas are exact copies of a stored item; they are used to place data closer to the points of access such as geographical preferences. When a replica is created, an exact clone of the original data is created in the storage arrays.

Access Control

Access controls defines who can access the storage objects and what they are allowed to do. For example, a user or a user groups can be assigned only read or write or both access to a file. Other types of access control rights to an object are write, delete, and full control of the object.
