Public cloud storage is infrastructure as a service (IaaS) that provides block, file, object and hybrid cloud storage services delivered through various protocols. The services are stand-alone, but often used in conjunction with compute and other IaaS products. The services are priced based on capacity, data transfer and/or number of requests. The services provide on-demand storage capacity and self-provisioning capabilities. Stored data exists in a multitenant environment, and users access that data through the block, network and REST protocols provided by the services.

Gartner defines the market for cloud database management systems (DBMSs) as the market for software products that store and manipulate data and that are primarily delivered as software as a service (SaaS) in the cloud. Cloud DBMSs may optionally be capable of running on-premises, or in hybrid, multicloud or intercloud configurations. They can be used for transactional and/or analytical work. They may have features that enable them to participate in a wider data ecosystem. They typically persist data using proprietary components in a durable manner, enabling a full range of create, read, update and delete operations.

The experience is quite horrible, if we make some minor mistake then we have to pay big.But after familiar with this software, it makes so easy to store and retrieve any amount of data, at any time, from anywhere on the web. In my organization i can easily parse the file document from web.

Nous avons utilisé S3 pour une application développée en interne et hebergé sur AWS. L intégration a été simple notament avec les autres services AWS, nous avons pu automatisé ceraines étapes. Seul la gestion des droits peut etre complexe

S3 is a great, reliable place to keep your data if you are already using AWS, but don't fall down the rabbit hole of services. It is fast and easy to access the data

Business Data Analyst

everytime we need support it is slow to respond, speaks bad english or both. prices could be better (they had been) and latency sometimes breaks applications at critical times. overal, 8 out of ten would not use if there were a more enterprise friendly competitor

Technician in Copiers

I have had good experiences in the few times I used this object storage service because it offered industry-leading scalability, data availability, security, and performance. It provided me with easy-to-use management features so I could organize the data and set up refined access controls.

Project Manager

Excellent tool online to storage business data. We provide services to companies that want to explore the ecommerce, so we have a lot of information and pictures of all the products they want to sell, also several people of the office need access to this documents, like products feeds, to optimize them or just check if is available, so it´s no scalable to have this information in one computer or even in our servers. So We use this tool to storage the whole information. 

CEO Dahlia Web Designs LLC & Founder Hel

The system provides excellent storage facility. It allows for 'view' protection of files by letting you indicate the URL where the file may be read.  If you do need 'view' protection for your files, it is not intuitive how to set up. Documentation is not very easy to understand. Occasionally the 'make public' doesn't make all the files within a directory public. Paid tech support (inexpensive) was excellent at helping to resolve problem.
