Posit: Private Cloud Has Less Lock-In

Posit: A private cloud has less lock-in than a public cloud because realistic, practical alternatives exist and migration is possible

  • Moving between public cloud services is practically impossible.
  • It may never be possible.
  • Your business process is hostage to a third party and completely outside of your control from a timeline, cost and change view
  • Consider, your business is under threat and cutting costs is imperative. Your cloud provider is forcing a migration to a updated service and you have fixed time period to complete the upgrade process. You must spend to maintain service. Control is lost
  • Loss of control is a lock in

In private cloud, you have some greater degree of control over these issues. Its a tradeoff.

Addendum: 20170106-17:30

  1. Take for examples, the collapse of public clouds by VMware, Cisco, HPE, Verizon etc. All of these are forcing your business to undertake an activity outside of your control.
  2. Amazon is quite ruthless about forcing customers to fit its technology. Machines are force rebooted, products are deprecated and discontinued reguarly.
  3. Azure if forcing upgrades on its SQL products as a rapid pace, often beyond what customers are able to handle (they don’t have the resources to change their systems).

Response: Cisco iWAN costs : networking

Doing an initial look into the cost of deploying a Cisco iWAN to see how it stacks up against Viptela or another SDWAN provider. Does anyone know what components or licensing is required for this? I’m lost. I see it requires a Cisco APIC-EM to be setup, but then how does the licensing for this work?

Interesting the breadth of vendors discussion – Cisco iWAN, Meraki, Viptela, Cloudgenix, Talari, APIC-EM, Glueware etc. 

Comments like the following:

“Anything but iwan unless you prefer a complicated mess of technologies that pre date the tube television.” 

 “APIC-EM is a hot mess. I would not recommend using it at this time for anything more than seeing what a mess it is. I recommend you look at something like Glue Networks Gluware for your orchestration tool over APIC-EM. In the WAAS space we picked Riverbed over Cisco WAAS because it would have required replacing our current routers with a new model in the middle of our lifecycle management. In our case, Viptela and Cisco were about the same cost, with maybe a slight advantage to Cisco”

“The are several drawbacks to Viptela. They tout it as a router replacement, but it’s definitely not. Continue reading

Response: Vendor Frustrations on Subscription Pricing

The pain of software subscriptions is only just beginning. In this case, $vendor is being sneaky about unchallenged price increases.

MrFogg97 – Network Ramblings: Vendor Frustrations: “Today I sit here, last day of vacation. Skimmer though work email just so it doesn’t overflow. (I am pretty bad at the disconnection part). I have received 2 emails from vendor $. Basically telling me that my renewal is about 60 days past and wondering am I going to renew. Oh and they have graciously allowed me to continue to use the product. Along with this was a quote for 3 years for the product.”

Musing: Average Life Span on S&P Index

On average, your big corporate employer won’t be around in ten years.

Plan your career accordingly.

  • When the boss says “people are our most important asset” its not about you particluarly.
  • Don’t transfer responsibility for your life and career to someone else.
  • Don’t trust your employer to to be on your side, they can be but the company comes first, profits second…… and several steps later its you.

Now its a Microblog

The transition to Packet Pushers is complete.  My long-form technical and analytical writing is published there.

Etherealmind will become a “microblog”:

  1. I want to share links, thoughts, references, observations that I collect from reading and research.
  2. Posts with just a few sentences and link to the source.
  3. Its not practical to publish to Twitter, Facebook, LinkedIn etc individually. Nor do I want to, I own this content.

Looking Past The Cloud Computing Era

Presentation from Peter Levine at A16z on the theme of edge computing will see a return to distributed computing the in the years ahead. The amount of data collected/created at the network edge is vast You must process locally and then upload summaries. Device complexity and capability is increasing rapidly e.g. Cars, Smartphones. This supports […]
