As computer systems evolved with time the data increased multifold. Managing the data became a challenge. This is when the need for efficient data management was felt. It was then that the concept of data warehouse was introduced.
What is a data warehouse?
Data warehouse pertains to storing large amounts of data by a business electronically.
A data warehouse can be understood as a hub of business intelligence. Its main purpose is reporting and data analysis. It stores the current and past data at a single location. The data can be used by workers throughout an enterprise to create analytical reports.
The current trend indicates that most businesses are moving towards Cloud for various applications.
What is Cloud Data Warehousing?
Cloud warehousing or storage of data entails remote management, maintenance and back up of data.
Data warehousing in Cloud enables people to access and use data easily through the internet. This makes data sharing easier in Cloud compared to other environments. But most enterprises are concerned about security when it comes to data warehousing in the Cloud.
Cloud storage has its pros and cons. It is a good idea to weigh them before deciding whether to opt for them or not.
Let us see the benefits and drawbacks of Cloud Data Warehouse:
All Cloud storage devices have desktop folders for Mac’s and PCs. This simplifies the drag and drop of files between Cloud storage and local storage.
It facilitates sending web links to recipients through your email instead of emailing files to individuals.
3. Accessibility is enhanced:
Stored files can be easily accessed from anywhere via the internet.
4. Data Backup:
Cloud data warehouse stores important files required by the business. This serves as an emergency backup plan. In case of an emergency, the second copy of backup files can be easily accessed by the business through the internet.
5. Reduces Business Expenses:
Annual business operating costs can be drastically reduced by using Cloud storage. Storing data remotely does not require internal power. Hence, it results in further savings.
One of the greatest benefits of data warehousing in Cloud is data monetization. This is because it is highly useful in the case of high volume customer data such as retail or telecom.
However, Cloud data warehousing has certain drawbacks. Some of them can be overcome.
Let us now see the drawbacks and their solutions:
The drag and drop function to move a document into a Cloud storage folder should be used carefully. This is because there is a risk that the document will be moved permanently from its original location to the Cloud storage.
Solution: It is recommended to opt for ‘Copy Paste’ instead as this will enable retaining the document in its original location in addition to moving a copy to Cloud storage.
Many Cloud storage services have a limited bandwidth. If the business enterprises surpass the limit, there are significantly high charges for it.
Solution: There are some Cloud storage providers who provide unlimited bandwidth. It is recommended that the organization opts for a Cloud storage provider based on the bandwidth they use.
Your access to data is only possible as long as you have internet connectivity.
4. Data Security:
Most organizations are uncomfortable with the remote storage of important data. This is because there is a risk of data getting mingled with data of other organizations. Also, if the data falls into wrong hands, it could adversely affect the business.
In order to manipulate your data locally through multiple devices, you will need to download the service on all devices.
Each organization’s needs are unique. Hence, their requirements for data warehousing will also vary. After carefully weighing the pros and cons of Cloud data warehousing, the enterprise can decide whether to opt for it or not.
There are numerous cloud data warehousing service providers.
But while choosing one, there are certain factors to look for:
- Storage and computing should be separate
If the data storage is separated from the engine that does the computation, it will allow a greater data storage. It will also permit more engines as needed for processing it.
- On demand workload, specific engines should be created
The Cloud should be able to start different computing engines according to the workload.
- The optimizer should be based on the power of the Cloud
The optimizer must be able to use the abilities of the Cloud such as high computing power, memory at various speeds and costs and low-cost storage.
- Manage large volume and variety of data
The Cloud data warehouse should have the ability to process large amounts of basic unstructured data and extract structured data from them.
- Scalability and capability to replicate
In order to support a multi-repository, multi-cloud world, the Cloud data warehouse should be capable of moving the data at scale to and from the warehouse. It should also be able to replicate and synchronize the data.
From the trends, it is apparent that most business enterprises are adopting Cloud services due to the numerous benefits they offer. So, cloud data warehousing becoming a part of the data warehousing in the near future for most businesses is inevitable. It is recommended that the business analyzes its needs and chooses a vendor accordingly.
