While organizations may use either private or public cloud models, public cloud services have the maximum takers. This is because public cloud solutions are affordable; at the same time, they guarantee high reliability, scalability and high performance.
 
Which online cloud storage model you should choose?

When you choose public cloud for storage, you can offload the costs and management duties which you would otherwise have to take up for storage hardware. With online cloud storage, your cloud provider becomes responsible for storing data and managing hardware for storage. The provider will also maintain data center facilities like cooling systems, servers and power supplies.

Benefits offered by the Public Clouds:

- When you choose public clouds, you can benefit from cost-savings. This is because you are expected to pay only for resources you use and nothing extra. So, with online cloud storage, you are exempted from paying extra for resources you may have no use for. You can enjoy scalability and upscale or downscale your resources depending on the demand. This is why public clouds appeal more to businesses which are starting out and have limited funds. In public clouds, storage access is offered through the providers’ API. This is capable of uploading, restoring and managing data within the cloud.

- When you choose online cloud storage, you can get far better performance than possible from local networks. When a business faces peak periods of high demand, it is not required to maintain the maximum storage capacity for a whole year. Elastic storage lets companies upgrade and downgrade their capacity.

- With a public cloud model, you can get superior uptime and performance. Data gets stored in multiple locations all across the globe. This ensures that users can access data even when there are sudden outages in particular areas.

- The public cloud has a multi-tenant architecture. This may raise doubts about data security. But cloud security has dramatically evolved and risks of data getting intercepted or accessed by unauthorized personnel have reduced. Now, vendors implement proper tools to make sure that there are no breaches. Public cloud providers can also find out who accessed data at what time. They can even encrypt data when it is transit as well as when it is at rest. But how the provider secures data encryption may vary from one provider to another.

- Some vendors offer monthly subscriptions. Businesses can choose from primary or secondary or archival storage. With the public cloud pay-as-you-go model, costs are lower and clients can create and test application codes.

- For organizations which need to store data in an off-site location, the public cloud is beneficial. It is flexible and data can be recovered when there are disasters. Businesses can also store the rarely-accessed records in remote locations without having to buy expensive disks for archiving these. Public clouds help to accelerate data recovery time as data is always available on-demand. Public clouds allow businesses to add more capacity when there are traffic peaks.

- As storage is distributed globally, data can be quickly disseminated. So, users from different geographical locations can comfortably access the online data storage. So, there are faster download times for clients depending on their regions.
