If you are thinking about which data storage solution is suitable for you, this article compare data storage solutions like cloud or on-premise.
Cloud or on-premise storage is a debatable topic. Cloud storage has risks of data leakage due to accidental sharing, data containing URLs, intentional copying on personal drive, misconfiguration of cloud resources, and stored passwords.
The on-premise storage has perils of higher equipment costs, operational costs, and managing complexities of data.
What is Cloud Storage?
Cloud storage is an internet-dependent service that offers a data center to store your data in a remote location. Third-party service providers manage the files stored on external servers. The cloud provider installs and maintains the hardware, software, and supporting infrastructure. Data is hosted externally, but the accessibility to this data is anywhere, anytime, and using any device. It is a boon for companies having teams working remotely.
Cloud storage is for every type and size of business. There are mainly three types of storage, i.e., On-premise, Staas, and Hybrid Cloud. On-premise (self-hosted & self-managed), Staas (externally managed data centers to facilitate storage and syncing), and Hybrid Cloud (combination of On-premises and Cloud Networking).
What are Cloud Storage Procedures?
The client-server model is permitted storage via subscriptions requests by clients. They store data on an external server of the data center instead of any local storage disks/servers. The users can retrieve data from any location with an available device and a stable internet connection.
It is easy, secure, and quick, and it gives liberty to store all essential business records. Multiple choices in cloud service providers, pricing plan and storage level, etc., make your decision easy. Moreover, you benefit from free trials and free programs.
Why do organizations need Cloud Storage?
Data is nowadays treasured. The data points help in decision making, general operations, and providing a better customer experience. Remote storage improves accessibility, productivity, and efficiency of dealing with data. Data storage packages are cheaper than self-managed on-premise solutions. You save the costs of hiring experts to manage servers and avoid unnecessary expenses as you scale up and down as per your storage requirement, e.g., 10TB or 20TB.
What is On-Premise Storage?
On-premise storage is an IT team/partner-hosted and maintained infrastructure having complete control within an organization. The data is shared between local machines via nodes on the local network. You gain peace of mind at a higher cost for this solution. Selecting servers and maintaining the same requires IT expertise. Though the data seems secured, some basic security measures need to be adopted.
Remote Storage improves accessibility, productivity, and efficiency of dealing with data.
What are On-Premise Storage Procedures?
This server model is self-created, and storage permissions are joint decisions of IT and management. It has limited access to selective people and no access to external parties most of the time. They store data locally on an internal server of the company. The users can retrieve data from authorized locations approved by the organization.
It isn’t easy to manage, but some find it more secure and prefer to store all the vital business data internally. Multiple approaches to server capacity and infrastructure-related decisions require time, money, and technical expertise.
Why do organizations need On-Premise Storage?
Simply for the sake of preference or actual requirement does not matter, but it gives assurance of data safety to the customers. The companies have operational and managerial capabilities. Some companies want to stay in their comfort zone by not shifting to cloud storage. Few of them fear the change as the IT Partner withholds support.
