Twelve Reasons Why Private Clouds Are Better Than Public Clouds

A response to a ZDnet article by Joe McKendrick

Joe McKendrick reviews Jason Bloomberg's new book and posits that public cloud is better than private cloud and he provides twelve very valid reasons.

Yes, the debate is fierce between private and public..... security, cost, control, compliance

In response, here are my twelve reasons why private cloud is better than public

  1. Your organization controls the network and infrastructure of a private cloud
  2. You don't incur high MPLS costs - network costs to transfer data and workloads between your datacenter and the public cloud
  3. You are not susceptible to public cloud outages - Amazon apologized to Netflix in December
  4. What does it actually cost to use public cloud ? - Cloudyn can help you calculate
  5. Can you be compliant in the public cloud? New PCI standards help
  6. Is your data secure in the public cloud? here is one example
  7. You can appropriately size a private cloud instance, because you control the hardware and provisioning - Not all public cloud instances are created equal here is one example and an academic PDF
  8. Private cloud can be custom designed for your business
  9. Organizations already own datacenters and have virtualized so there is a small incremental cost to building out a private cloud
  10. You own the private cloud, you are accountable for success and failure.
  11. With a private cloud, there is no rogue IT problem, business units can self-serve from your cloud with no uncontrolled expenses.
  12. Your IT organization knows your business best and with technical tools like Puppet, Chef, Nagios etc can rapidly deploy the services you need internally

Caveat emptor (buyer beware) - James Staten outlines how an Enterprise private cloud can fail.

Most DevOps journeys involve several phases of maturity. Research shows that the inflection point where organizations begin to see maximum value is when they implement tight integration deploying their code to their infrastructure. Success at this level is the last barrier to at-will deployment. Storage, for instance, is more capable than where we read and write data. In his session at @DevOpsSummit at 20th Cloud Expo, Josh Atwell, a Developer Advocate for NetApp, will discuss the role and value extensible storage infrastructure has in accelerating software development activities, improve code quality, reveal multiple deployment options through automated testing, and support continuous integration efforts. All this will be described using tools common in DevOps organizations.
