In the realm of cloud computing, Cloud-Integrated Storage (CIS) is a term that carries significant weight. It refers to a system that combines local storage services with public or private cloud storage services. This integration allows data to be automatically tiered to the cloud, providing a seamless, scalable, and cost-effective storage solution.
As software engineers, understanding the intricacies of CIS is crucial. It not only helps in designing efficient systems but also in managing and maintaining them effectively. This glossary article aims to provide an in-depth understanding of Cloud-Integrated Storage, its history, use cases, and specific examples.
Definition of Cloud-Integrated Storage
Cloud-Integrated Storage is a data storage system that integrates on-premises storage with cloud storage services. The primary goal of CIS is to provide a unified storage solution that can handle large volumes of data while reducing the cost and complexity of data management.
It combines the performance and security of local storage with the scalability and resilience of cloud storage. The data in a CIS environment can be automatically tiered, moved, or copied to the cloud based on predefined policies. This ensures optimal use of storage resources.
Components of Cloud-Integrated Storage
A typical CIS system consists of two main components: the on-premises storage system and the cloud storage service. The on-premises storage system, also known as the CIS appliance, is a hardware device that provides local storage and acts as a gateway to the cloud. It is responsible for data deduplication, compression, and encryption before the data is sent to the cloud.
The cloud storage service, on the other hand, provides scalable and resilient storage space. It can be a public cloud service like Amazon S3 or Google Cloud Storage, or a private cloud service hosted in a data center. The cloud storage service is responsible for storing the data and making it available for retrieval when needed.
Explanation of Cloud-Integrated Storage
Cloud-Integrated Storage works by integrating local storage services with cloud storage services. The local storage, also known as the primary storage, stores the most frequently accessed data, while the cloud storage, also known as the secondary storage, stores the less frequently accessed data.
Data in a CIS system is automatically tiered to the cloud based on predefined policies. These policies can be based on the age of the data, the frequency of access, the type of data, or other criteria. When data is tiered to the cloud, it is first deduplicated, compressed, and encrypted by the CIS appliance to reduce the storage space required and to ensure data security.
Working of Cloud-Integrated Storage
The working of a CIS system can be divided into three main steps: data ingestion, data tiering, and data retrieval. During data ingestion, data is first stored in the local storage. The CIS appliance then performs data deduplication, compression, and encryption to reduce the storage space required and to ensure data security.
During data tiering, the CIS appliance automatically moves or copies the data to the cloud based on the predefined policies. The data in the cloud is stored in a compressed and encrypted format, and it can be retrieved and decrypted when needed. During data retrieval, the requested data is first searched in the local storage. If it is not found, the CIS appliance retrieves it from the cloud, decrypts it, and delivers it to the user.
History of Cloud-Integrated Storage
The concept of Cloud-Integrated Storage emerged with the advent of cloud computing in the late 2000s. As organizations started to generate and collect more data, the need for a scalable and cost-effective storage solution became apparent. This led to the development of CIS, which combines the benefits of local storage and cloud storage.
The first CIS systems were introduced by companies like StorSimple and TwinStrata in the early 2010s. These systems were primarily designed for enterprise use, and they provided a seamless way to integrate on-premises storage with cloud storage services. Over the years, CIS has evolved and matured, and it is now a key component of many cloud-based data management strategies.
Evolution of Cloud-Integrated Storage
The evolution of Cloud-Integrated Storage has been driven by the increasing need for scalable and cost-effective storage solutions. In the early days, CIS systems were primarily used for backup and archiving purposes. However, with the advent of big data and the Internet of Things (IoT), the use cases for CIS have expanded to include data analytics, disaster recovery, and more.
Today, CIS systems are more sophisticated and feature-rich. They support a wide range of cloud storage services, and they provide advanced features like data deduplication, compression, encryption, and automatic tiering. They also support hybrid cloud environments, allowing data to be moved between on-premises storage and multiple cloud storage services based on the business needs.
Use Cases of Cloud-Integrated Storage
Cloud-Integrated Storage is used in a variety of scenarios, ranging from data backup and archiving to big data analytics and disaster recovery. It is particularly useful in scenarios where large volumes of data need to be stored and managed efficiently.
One of the most common use cases of CIS is data backup and archiving. By integrating local storage with cloud storage, CIS provides a scalable and cost-effective solution for backing up and archiving data. The data can be automatically tiered to the cloud, reducing the storage space required on-premises and ensuring that the data is available for recovery when needed.
Data Analytics
Cloud-Integrated Storage is also used in data analytics. By storing the data in the cloud, CIS allows for scalable and cost-effective data storage. This makes it possible to store and analyze large volumes of data, which is crucial for big data analytics.
In addition, the automatic tiering feature of CIS ensures that the most frequently accessed data is stored in the local storage, reducing the latency and improving the performance of data analytics operations.
Disaster Recovery
Another use case of Cloud-Integrated Storage is disaster recovery. By storing the data in the cloud, CIS provides a resilient and geographically distributed storage solution. This ensures that the data is safe and available for recovery even in the event of a disaster.
The automatic tiering feature of CIS also ensures that the most critical data is stored in the local storage, reducing the recovery time in case of a disaster.
Examples of Cloud-Integrated Storage
There are several examples of Cloud-Integrated Storage in the market today. These include solutions from major cloud service providers like Amazon Web Services (AWS), Google Cloud, and Microsoft Azure, as well as solutions from storage vendors like NetApp and Dell EMC.
Amazon's AWS Storage Gateway, for example, is a cloud-integrated storage service that provides a seamless way to connect on-premises applications to AWS storage services. It supports file, volume, and tape storage modes, and it provides features like data deduplication, compression, and encryption.
Google Cloud Storage
Google Cloud Storage is another example of a cloud-integrated storage service. It provides a unified object storage for developers and enterprises, and it integrates with Google's own cloud services as well as third-party cloud services. It supports multiple storage classes, including standard, nearline, coldline, and archive, allowing data to be tiered based on the frequency of access.
Google Cloud Storage also provides features like data deduplication, compression, and encryption, and it supports a wide range of data transfer methods, including online transfer, offline disk import, and the Google Cloud Storage Transfer Service.
Microsoft Azure StorSimple
Microsoft's Azure StorSimple is a cloud-integrated storage solution that combines the performance of local storage with the scalability and resilience of Azure cloud storage. It provides a seamless way to tier data to the cloud, reducing the cost and complexity of data management.
Azure StorSimple supports a wide range of use cases, including data backup and archiving, disaster recovery, and big data analytics.
