Similarly, moves by both Microsoft and Amazon, among others, to set up local data centres in the EU will not on their own protect European data unless that is encrypted by the companies themselves, and the cloud computing providers do *not* have access to the keys. Indeed, if the data is encrypted in this way, local storage is not so important, since the NSA will have an equally hard time decrypting it wherever it is held - as far as we know, that is.
Because of that recent US court judgment ordering Microsoft to hand over emails held in Ireland, many people are now aware of the dangers of cloud computing in the absence of encryption under the control of the customer. But very few seem to have woken up to the problems of backdoors in proprietary software that I mentioned at the start of this post. One important exception is the German government, which according to Sky News is working on an extremely significant law in this area
Earlier this week, cloud provider Joyent did a surprising thing: It shared its finely tuned cloud software, SmartDataCenter, under an open-source license.
But while it might seem like the company is giving away its high-value intellectual property at a time when Amazon, Google, and Microsoft have made the public cloud market ultra-competitive, Bryan Cantrill, the company’s chief technology officer, actually has some very smart justifications for the move, which he spelled out in a blog post.
Joyent and Canonical are the latest cloud firms to open source their container technologies.
Joyent, which recently raised $15m in funding, announced a container-based cloud-hosting platform that could be used as the basis for running large-scale, big-data tasks
Not all the action is happening at the OpenStack Summit in Paris. In a bold move, cloud specialist Joyent has announced it's open-sourcing its core technology. That includes software that competes directly with OpenStack and enables high-performance use of container technology like Docker. The newly open projects enable easy management of containers at scale.
