OpenNebula Cloud API

Amazon, OGF OCCI, OpenStack, Google Cloud, DMTF CIMI or vCloud?

Last week the OpenNebula project launched a survey to collect feedback from their community regarding what is their preferred interface for cloud consumers and how they should invest their resources in cloud API enhancement and development. The survey was open for two days receiving feedback from almost 200 OpenNebula clouds.

Targeted to OpenNebula cloud administrators, its aim was firstly to have information about the level of use of the two cloud APIs offered now by OpenNebula, namely AWS and OGF OCCI. The results show that:

  • 38% do not expose cloud APIs, their users only interface through the Sunstone GUI
  • 36% mostly use the AWS API
  • 26% mostly use the OpenNebula's OCCI API or the OCCI API offered by rOCCI

Then they asked how they would like us to invest our resources to enhance the Cloud APIs. The results show that:

  • 47% to enhance the existing AWS API implementation
  • 21% to enhance the existing OGF OCCI implementation
  • 10% to implement the OpenStack API
  • 10% to implement the vCloud API
  • 6% to implement the Google Cloud API
  • 6% to implement the DMTF CIMI API

They also received many valuable additional comments mostly stating that "AWS is the de-facto standard and an executive-friendly selling point""OGF's OCCI is the only independent community-driven standard""OpenStack API is still not stable and fully documented", and "Google Cloud API represents a big opportunity in the medium term".

Guided by these results, their plans for the near future are to enhance and extend our implementation of the AWS API and to offer OCCI compatibility through the rOCCI component. Of course, if your organization is interested in implementing one the less demanded Cloud APIs, they can provide you with the needed support.

The challenges of aggregating data from consumer-oriented devices, such as wearable technologies and smart thermostats, are fairly well-understood. However, there are a new set of challenges for IoT devices that generate megabytes or gigabytes of data per second. Certainly, the infrastructure will have to change, as those volumes of data will likely overwhelm the available bandwidth for aggregating the data into a central repository. Ochandarena discusses a whole new way to think about your next...

Cell networks have the advantage of long-range communications, reaching an estimated 90% of the world. But cell networks such as 2G, 3G and LTE consume lots of power and were designed for connecting people. They are not optimized for low- or battery-powered devices or for IoT applications with infrequently transmitted data. Cell IoT modules that support narrow-band IoT and 4G cell networks will enable cell connectivity, device management, and app enablement for low-power wide-area network IoT. B...

When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...
