Building a cloud storage platform is not an easy task. Dropbox was one of the first to break into the consumer cloud storage space, followed by Box. Over in Asia, Kleii aims to take advantage of the opportunities in the region by being the consumer cloud solution for the region. By understanding their Asian customers, Kleii has been able to build a strong following in a space that is being dominated heavily by its Western competitors.

Just three months after launching their web application, Kleii hits 100,000 registered users. That number has tripled over the past three months.

With its Western competitors having a head start over Kleii, the team at Kleii are not shying from analysing what their competitors are doing and adapting their strategies to a market that they understand better. Spotting an opportunity with student users, Kleii launched a similar campaign to Dropbox’s Space Race, focusing heavily on education institutions in Asia.

Kleii announced on its blog that it is expanding its services to Australia with a new data center in Sydney. e27 caught up with co-founder Nguyen Tuan Son to find out more about the latest expansion and what it takes to run a cloud storage platform in Asia.

Kleii recently expanded its operations to Australia, can you share with us the strategy behind this expansion?

First of all, we always wanted to become a world class operation. We are growing quite fast and well in Vietnam and Southeast Asia countries. Now, we would love to expands our service to Australia, where cloud computing takes a stronger meaning in Australia today. In the next two years, we want to become the leading cloud computing service in Asia and Australia. The strategy at this point of time is simple. Southeast Asia first, then Asia, then Australia, and move on.

What user traffic does Kleii see on a daily basis?

Now we have around 30,000 visitors with around 80,000 page views per day. Since we launched six months ago, 300,000 users have registered to use our service. More than 4TB of data are transferred everyday. Our users love to upload their documents, music and videos to Kleii since we allow to stream multimedia files to any devices. 70 percent of our users are from Vietnam and Southeast Asia, the rest are from Japan, America and Brazil.

Protecting users’ data is important for Kleii, how does the team manage this?

We do our best to ensure that our users’ data are secured in three ways:

Secured storage

We encrypt the files that you store on Kleii using the AES-256 standard, which is the same encryption standard used by banks to secure customer data. Encryption for storage is applied after files are uploaded, and we manage the encryption keys. Kleii uses the highly durable Amazon Simple Storage Service (Amazon S3) for data storage.

Secured transfers

Your files are sent between Kleii’s desktop clients and our servers over a secure channel using 256-bit SSL (Secure Sockets Layer) encryption, the standard for secure Internet network connections. Your files are sent between Kleii’s mobile apps and our servers over a secure channel using 256-bit SSL encryption where supported. Your data are sent between your browsers and our servers over a secure channel using 256-bit SSL encryption.

Data back-ups

Kleii keep redundant backups of all data over multiple locations to prevent the remote possibility of data loss. In the unlikely event that this redundancy were to fail, Kleii’s folders linked to a desktop computer client will still contain copies of your files (except files you’ve chosen not to sync using Selective Sync).

What made you choose Amazon Web Services for Kleii?

Amazon Web Services is a wonderful cloud computing infrastructure for any company. As a new startup such as Kleii, it was wise to choose a cloud provider like Amazon Web Services as we can save tons of time and money needed to build and manage our own infrastructure. Furthermore, with help from the Amazon Web Services team, Kleii can grow faster by focusing on building our vision and product. Based on the existing infrastructure of Amazon Web Services, Kleii was able to build and scale our system to multiple continents and serve customers worldwide. Kleii is using Amazon CloudFront with Amazon EC2 and Amazon S3 for the AWS Asia Pacific (Sydney) Region.
