Cloud Predictions Rob Clyde

UNCONVENTIONAL CLOUD PREDICTIONS
With 2012 being a bumper year for the cloud computing industry, what exactly can we expect for 2013? Rob Clyde gives his predictions for the year ahead
2013 will be an exciting year for cloud computing for all the standard reasons: exponential growth, new technologies, greater understanding, etc. Predicting easily observable cloud trends is not really prediction; it’s simply stating the obvious. I believe the best predictions look deeper and identify trends that underlie the superficial ef- fects we see on the surface. In that spirit, rather than repeat what everyone already agrees on, I would like to make three predictions that are perhaps a little more controversial, or at least less obvious:
BARE-METAL CLOUDS WILL CONTINUE TO GROW
Many people think that virtualisation is a requirement for cloud computing. This is a common fallacy, though some vendors want to perpetuate the myth. Numerous clouds, especially private clouds, utilise bare-metal hosts in addi- tion to virtualised hosts. Some applications need the en- hanced I/O or processing performance that comes from running on physical hardware. If these applications don’t require the benefits of virtualisation – migration, multi- tenancy, etc. – a bare-metal deployment can be best. However, bare-metal machines don’t have to give up the management benefits provided by cloud infra- structure – self-service portals, usage-based payment models, etc. The best cloud management platforms can manage heterogeneous hosts inside a single cloud en- vironment, deploying services on physical or virtual hosts as needed. Rather than a world where all clouds are

virtual and homogeneous, I predict a world that is more diverse. Heterogeneous clouds will become the new standard in private clouds in 2013 and beyond. This trend will continue to grow, as organisations learn to choose the right platform for the right job.
CLOUDBURSTING WILL NOT BE SIGNIFICANT IN 2013
While there is a lot of talk and hype about cloudbursting, I don’t believe it will be significant in 2013. The concept of moving workloads dynamically between private and public clouds sounds desirable, but is not terribly use- ful in practice. Some applications fit very well in public clouds, especially if they have bursty, fast growing, or otherwise unpredictable work- load. Other applications are unlikely to ever leave the private cloud for secu- rity or economic rea- sons. Applications are likely to be deployed at the outset in either the public cloud or the private cloud, depend- ing on which environment is best for them. Since the reasons behind that placement
decision usually don’t change over time, dynamic cloud- bursting from private to public clouds is rarely useful. Cloudbursting hype will continue in 2013, but few will actually use it.
