Cloud-based advantages versus on-premise storage

What is the difference between cloud based and on-premise storage?

Cloud based storage is a cloud computing model (often referred to as ‘traditional’ or ‘public’ cloud) in which data is stored on remote servers accessed from the internet or ‘cloud’. It is maintained, operated and managed by a cloud storage service provider on a storage server that is built on virtualisation techniques.

On-premise (on-prem) storage refers to a private infrastructure that companies house in their own facilities and maintain themselves.

Advantages and disadvantages of cloud-based storage

Advantages of cloud-based storage include:

  1. Accessibility:files stored in the cloud can be accessed from anywhere that has an internet connection.
  2. Speed:tests have shown that when the cloud is supported by the right enterprise technologies, the speeds achieved can rival onsite scores.
  3. Cost savings:the cost of cloud-based storage for a small or medium sized organisation dependent on how much storage they require. The various cloud providers have different costs for the amount of storage required by the business. Across a year this will reduce the operating costs as it doesn’t depend on internal power to store information.
  4. Disaster recovery:all businesses should have an emergency backup plan and cloud storage can be used like this by creating additional copies of important files and saving them in an encrypted cloud folder.

Disadvantages of cloud-based storage include:

  1. Security and privacy:there have been concerns over valuable and important information being stored remotely. Before adopting cloud-based storage, you should be aware that you are giving sensitive data to a third-party cloud service provider and this could potentially put your organisation at risk. EPX Technical Services choose our providers carefully to minimize the potential risks that come with unreliable third parties.
  2. Data management:managing data in the cloud can be difficult as cloud storage systems have their structure and your existing storage management system may not integrate well with it.
  3. Bandwidth restrictions:depending on what service you choose, there may be a bandwidth allowance. If your business doesn’t plan properly and surpasses the allowance, then charges could be extremely costly.

Advantages and disadvantages of on-premise storage

Advantages of on-premise storage:

  1. Configurability: having a server on-site may allow you under some circumstances to have more configurability – you are able to decide on upgrades and system changes.
  2. Control:in an on-premise environment, organisations retain all of their data and are fully in control of what happens with it.
  3. No reliance on internet:you do not need to rely on internet connectivity or external factors to access your data.
  4. Bandwidth and capacity:with regard to on-premise storage, bandwidth and capacity can be increased physically by putting new servers in operation. Although sometimes challenging, on-premise allows organisation to build customised configurations to resolve specific issues.

Disadvantages of on-premise storage:

  1. Cost:this requires an initial installation of hardware and infrastructure to ensure it will work efficiently and effectively. It also requires capital investment in software licenses, in-house support staff and longer integration periods.
  2. Responsibility:with on-premise systems, the organisation is responsible for maintaining server hardware and software, data backups, storage and disaster recovery. This can prove to be expensive for smaller businesses to do correctly, leaving them vulnerable.
  3. Updates:on-premise solutions typically have a slower cycle to release updates. The updates may require hardware and software changes and will involve heavy IT involvement to execute. Did you know: EPX test Windows updates before rolling them out to clients.
  4. Disaster recovery:on-premise disaster recovery resources are vulnerable to hardware-level disasters, such as fires, floods, robberies or another catastrophic event.
