Cloud storage for any new use case

Storadera cloud storage is built from ground up to be frugal and lean technically and operationally. By doing this we can offer way better and simpler pricing than big 3 competitors AWS, Google and Microsoft. On top of existing use cases, better and simpler pricing opens up totally new areas where it becomes sensible to host your data safely in the cloud.. Tommi Kannisto, CEO and founder of Storadera

★ Storadera Space is a S3 compatible cloud object storage service ★ Secure, scalable, predictable pricing, instantly available ★ We are not end user oriented file storage service (Dropbox, Drive). Storadera is not meant to replace those What is Storadera and what not?

Problem Companies may choose not to use cloud storage because: ★ Pricing is complex and not predictable ★ Price is too high ★ Technically complicated to use

★ Possible high costs due to hidden fees ★ Complicated pricing structure ★ Unpredictable bill if not experienced user ★ Possible high costs due to hidden fees ★ Almost all are US companies Problem with competitors

The simplest pricing that is understandable also to non-IT professionals Most transparent pricing Industry agnostic and targeted for B2B customers, but also usable by B2C B2B oriented Being frugal in all aspects of service development to ensure fast and reliable service and ultimately provide fast storage on commodity HW Frugality in everything To be the first choice for companies to start new journey for cloud storage for any new use case To be the first choice Cloud storage for any new use case Strategy

We have built our service on not micro but medium sized services. For storage, performance matters. For storage, we have 3 main components. ★ S3 API - it is responsible for security and sanity checks ★ Worker - this is where “work happens”, CPU performance heavy tasks like parity and hash calculations ★ Drive - responsible for interacting with physical spinning Drives. This service is heavily IO bound. Physical spinning hard disks are slow by nature. We make the service fast to make things parallel on other levels so that all of our hard disks get roughly equal load on accepting new data. Service architecture

to be compliant with main industry accepted regulations like ISO27K1 (in process), SOC 2 etc Business model Service provider Deployment models Compliance Partnerships Pricing Transparency partner can own HW: as part of Storadera grid as dedicated partner grid to remain service provider and operate all deployments no on-prem licensing model is planned the most transparent cloud storage for companies, absolutely no additional fees simplest pricing model on the market, only 1 line in price list revenue share model with different types of partners Several deployment scenarios:

6 eur per stored TB calculated as monthly average Easy predictability No delete penalties No min object size No micro charges No egress fees 5x better price Fair usage policy applies S3 API calls are not charged Storage cost is calculated based on actual object size Storage cost is calculated based on actual time object is stored Actual monthly cost is easily predictable and helps to lower the barrier for cloud adoption Pricing
