Data Warehouse is a database enterprise system used to store data and other information from multiple sources. Cloud Data Warehouse is basically a cloud storage system to manage all the collected resources in a cloud space. Data Warehouse within the area of cloud computing helps to accomplish business service flawlessly in a private cloud.

Cloud Data Warehouse is a highly sophisticated designed and integrated cloud management system used to optimize Business Intelligence (BI) analytics and scalability. Cloud Data Warehouse management system does not require any separate physical data centers to store or manage the data [1]. Therefore, Cloud Data Warehouse focuses on organizational growth and permits to pay attention merely to business continuity without managing the server room [2].

  1. Traditional Data Warehouse is an on-premises physical data storage system, whereas Cloud Data Warehouse is a cloud data storage system.
  2. Traditional Data Warehouse requires separate hardware to run. However, no hardware is required for Cloud Data Warehouse since it is a cloud concept.
  3. A separate server room is required near the office premises to set up a Traditional Data Warehouse shown in the Image Below. On the other hand, Cloud Data Warehouse does not require any separate server room or data center for its installation.
  4. Traditional Data Warehouse is not portable and scalability is less because It is quite impossible to shift a Traditional Data Warehouse system from one place to another. Simultaneously, the Concept of portability is absent in the Cloud Data Warehouse system, thus Cloud Data Warehouse is more scalable.
  5. To access the data stored within a Traditional Data Warehouse system, the user should remain present in person near the Data Warehouse where it is located. Alternatively, the data stored in Cloud Data Warehouse can be easily accessible from anywhere in the world.
  6. Maintenance is required in the case of a Traditional Data Warehouse since it includes separate servers, hardware, wires, cables, etc. Separate staff also needs to be recruited to manage the Traditional Data Warehouse. On the other hand, Third party cloud service providers took complete responsibility for the maintenance, updates, hardware, software, etc. in the case of Cloud Data Warehouse.
  7. Installation of a Traditional Data Warehouse requires much time and human support, whereas Cloud Data Warehouse Installation is very easy.
  8. Traditional Data Warehouse is less flexible and scalable. Traditional Data Warehouse needs purchasing of additional hardware for its expansion. At the same time, Cloud Data Warehouse is highly flexible and scalable. Cloud Data Warehouse is very easy to redesign and mold according to the company’s needs and desires.
  9. Traditional Data Warehouse is costly due to the involvement of expensive hardware, separate server room, maintenance staff, etc. Concurrently, Cloud Data Warehouse is comparatively cheaper than Traditional Data Warehouse. In the case of Cloud Data Warehouse, payment should be made for only the utilized memory space.
  10. Many risk factors are associated with Traditional Data Warehouses. Traditional Data Warehouses are not a safe option for disaster recovery during natural calamities, military war, hardware failures, etc. During any catastrophe, it is difficult to retrieve the stored resources from a physical storage system. Besides, Cloud Data Warehouse is more secure and safer than Traditional Data Warehouse. The only threat is cyber-terrorism attacks and hacking.
  11. Traditional Data Warehouse is an offline process, whereas Cloud Data Warehouse is an online process. Cloud Data Warehouse requires an active internet connection.
  12. Data recovery speed is slower in Traditional Data Warehouses. It depends on copying speed, system specifications, processor speed, etc. In contrast, Data recovery is much easier and faster in Cloud Data Warehouse. It depends on the internet and bandwidth speed.

Benefits of adopting a Cloud Data Warehouse

Cloud Data Warehouse can provide benefits in many ways. Some of them are pointed out below as follows [4]. Image also demonstrates the fundamental merits of Cloud Data Warehouse.

  • Accessibility: Cloud Data Warehouse does not restrict its users to access the cloud storage data remotely. In simple words, Cloud Data Warehouse allows its user to access the cloud data at any time from any geographical location.
  • Scalability and flexibility: It is very difficult for any company to predict the future business market. As a result, Cloud Data Warehouse allows scalability to the unpredicted businesses to expand or contract data volume according to their needs. Cloud Data Warehouse does not require any external devices as data volume increases.
  • Maintenance: Separate attention on the maintenance of Cloud Data Warehouse is not required, as the cloud service providers take care of this matter.
  • Cost: Cloud Data Warehouse is cost-effective due to the absence of expensive hardware, server room, and maintenance staff.
  • Performance: The performance of Cloud Data Warehouse is generally high due to the presence of columnar storage and MPP features. These features are capable of processing real-time cloud analytics and quicker running of queries than a Traditional Data Warehouse system.
  • Efficiency: Cloud Data Warehouse consists of multiple servers to share the loads equally. These servers manage enormous amounts of data efficiently without any time lapse.
  • Data storage: Data storage option is not a barrier in Cloud Data Warehouse systems. Nowadays most of the cloud service providers offer a pay-as-you-go subscription model as a paying option for the fraction of storage space companies use.
  • Integration: Cloud Data Warehouse easily integrates data including unstructured and semi-structured from distinct multiple sources to other applications. Sharing data is also easy in Cloud Data Warehouse.
  • Disaster recovery: Cloud Data Warehouse is designed in such a way as to ensure better safety and efficient data recovery during any natural or man-made disasters like earthquakes, floods, military attacks, riots, etc. Cloud Data Warehouse took a backup of all the essential information in the cloud storage on a regular basis without worrying about purchasing additional equipment.

Challenges of a Cloud Data Warehouse

Besides the fact that Cloud Data Warehouse is extremely advantageous to businesses, more often the companies face frequent challenges while implementing the Cloud Data Warehouse concept. Here are some of the key threats associated with Cloud Data Warehouses [5].

  • Cost: Although Cloud Data Warehouse is economically cheaper than Traditional Data Warehouse systems, sometimes Cloud Data Warehouse can be very expensive. Since the Cloud Data Warehouse concept runs on a subscription-based model, therefore, the companies have to spend a fixed monthly or annual rent to retain the benefits of Cloud Data Warehouse.
  • Lack of expertise: Cloud Data Warehouse facility is very complex and requires excellent IT skills to run the system.  Most of the companies were not able to implement the Cloud Data Warehouse service due to a lack of proper knowledge and expertise in the field. The companies should recruit professional IT experts having in-depth technical and cloud security understandings to manage Cloud Data Warehouse systems.
  • Security issue: In some cases, Cloud Data Warehouse also fails to deliver strong security alerts. A major reason includes the possibility of hacking or cyber-attack concerns. There is always a probability of hacking the confidential information stored in the cloud space and abusing the same by cybercriminals.

Another security issue can be the trust factor that exists between the customer and the cloud service provider. Cloud Data Warehouse service is provided by a 3rd party company, thus all the deposited resources in the cloud storage are under the surveillance of service providers. The vendors can easily get access to the user’s data if they want. Hence, the customer should choose a trusted cloud service vendor.

  • Data movement: Another problem associated with Cloud Data Warehouse is retrieving the data back into the company’s databases from the cloud. To extract the resources back to the on-premises servers and data centers, ETL (Extracts, Transforms, and Load) needs to be built, and the cost may reach sky-high.

Moreover, loading huge quantities of data into the Data Warehouse in different formats is a very critical task for engineers.

  • Standardization: Different cloud service providers offer different pricing models to the customers for enjoying the benefits of Cloud Data Warehouse service. Hence, most of the time the customers get confused and find it difficult to choose the right one.

It is also challenging for companies to predict the accurate cloud space size that should be purchased in order to utilize the storage efficiently. According to statistics reported by the 2018 RightScale State of The Cloud, 35% of the Cloud Data Warehouse storage is being wasted by the companies seeking the Data Warehouse facility.
