Docker Data Containers


photo by

One challenge with Docker is having persistent storage for a container especially when that container gets restarted on another VM host and we want it to point to the same data. If we add in Delphix with Docker we can easily move persistent data and a docker container to a new host.

For the docker container we will use wordpress that leverages a MySQL database for it’s persistent datastore.
In this example I (more...)

This article lists some of the key capabilities that Delphix provides over and above Storage Snapshot based cloning solutions to meet the increasing business demand for Agile Development.

I’ve blogged about this before in

First it is useful to contrast the distinct goals and implementation behind Storage Snapshots and Delphix.

DB2 virtualized on Delphix

| Nov 10, 2015


Delphix is tightly integrated with PostGres, Oracle, Sybase and SQL Server but here is an example of  impressively easy workflow with DB2 which can be setup with a few extra scripts.


Second wave of cloud migration

A second wave of cloud migration is now happening after the initial hiccups of


Reaction to Shadow IT

  • Misaligned Expectations
  • Increased Data Exposure and Administrative Surface Area of Risk
  • Choice of newer better cloud options now available after initial “wrong choice”
Reaction to Shadow IT: A significant amount of public cloud use over the past few years was done without IT oversight and approval. As companies develop their formal cloud (more...)

What is Devops?

As has been noted many of times, DevOps is a term that is hard to define.

DevOps is a term that is so easily misapplied in the enterprise that it’s popularity threatens adoption.

If you can’t define it for the bean counters – it might as well not exist at all.

 Tim O’Brien, Gleanster

Thus being able to clearly define DevOps is crucial to its success.


IDC report: Virtual Data 461% ROI over 5 years

read the full IDC report on Virtual Data here.



Here are some key sound bites from the report:

“Data has turned IT departments into business enablers. Data acts as a tax on IT operations when IT departments cannot do what businesses need them to do because they are too busy ‘keeping the lights on.’ ”

“When we bought Delphix, the original reason was all of the terabytes we were avoiding. But now, the main benefit for (more...)

Make it easy or die (software is eating the world)

Software is eating the world

  • We see taxis being beaten out by Uber and Lyft.
  • We see hotels being undercut by Airbnb.
  • We see brokerage firms undercut by Ameritrade and Etrade.
  • We see retailers under cut by Amazon.

Today it’s all about developing software that makes access to your product easier.

We are also seeing the same thing happen in IT where cloud such as AWS is undercutting industry hardware vendors like Oracle, Netapp, EMC


Steve Jobs : the journey of simplicity

Steve Jobs sets a great perspective on the journey of simplicity. It starts from simple, goes through complexity and ends up in simplicity. 

“When you start looking at a problem and it seems really simple, you don’t really understand the complexity of the problem. Then you get into the problem, and you see that it’s really complicated, and you come up with all these convoluted solutions. That’s sort of the middle, and that’s (more...)

Diff’ing AWR reports

I don’t know if you are ever asked to compare to AWR periods. AWR period comparison is pretty easy if you have access to the two periods in the same AWR repository. AWR in the same repository can be compared with

         [db_id ],
         [instance id],
         120, -- start snapshot id
         121, -- end snapshot id
         [db_id of target,
         [instance id] ,
