Additional thoughts about Cloud Portability

Additional thoughts about Cloud PortabilityAdditional thoughts about Cloud Portability

 

Despite how much I love the Cloud, it would be foolish to ignore the many challenges that it poses. And, when concepts such as Liquid IT or Multi-Cloud become part of the agenda, one of those is, without a doubt, Portability.

Back when I was a member of the Atos Scientific Community, I was one of the authors of a whitepaper that addressed this very same topic. Since then, I was fortunate enough to witness other points of view about the subject and some have certainly got me thinking.…

The Limits of Shared Hosting

Published July 27, 2012 by Carlos Veira

SharedHostingLimits-201207-0Have you ever wondered which is the real difference among different offerings besides the fact that your applications run on a shared server? In fact, most of the times, this seems to be a tricky question because most service providers describe the boundaries and limits of their services based on the following common parameters:

  • The resource type and quota: storage, bandwidth, mail boxes, mail lists, FTP accounts, database instances, etc.
  • The underlying platform: Windows (IIS/Apache) or Linux (Apache) under whichever version.

Ramblings of a 64 bit Desktop User

Published April 11, 2010 by Carlos Veira

Now that I have taken some time to feel how someone deals with a 64 bit desktop, I have certain “confidence” to write about this. Of course, this is only my experience and, obviously, doesn't pretend to be a universal opinion. The following notes and comments refer mainly to Windows 7 Ultimate 64-bit.

First of all, it's safe, usable and seems mature enough. The drivers diversity is more than acceptable and, finally, you  take advantage of the hardware you have purchased for.…

APIs and the “Technology Mix”

Published April 11, 2010 by Carlos Veira

Today I would like to recall a really nice conference I saw last January: “Infrastructure in the Cloud Era”. This presentation was performed at O'Reilly Velocity Conference 2009 by Adam Jacob (Co-Founder at OpsCode) and Ezra Zygmuntowicz (Co-Founder at EngineYard).

They cover the theory of how you should be thinking about building a Fully Automated Infrastructure classifying their analysis in the following areas:

  • Bootstrapping: Corporate Approvals, Agile Approvals, Cloud.
  • Configuration: Manual, Ad-Hoc, Infrastructure as Code.

“Why cloud vendors lie to you and how they steal your money”

Published October 19, 2009 by Carlos Veira

The following video shows one of the best presentations I've happen to see describing one of the most significant changes we are living today.

This is a short description from blip.tv:

This session examines the concept of cloud computing, its benefits and risks and why it matters. We then explore the difference between private and public clouds and the importance of open source in this field. Finally we take a look at the future of this industry and use all these concepts to explain “why cloud vendors lie to you and how they steal your money.”

OpenSLIM & NMTools v3.33b0!

Published August 15, 2009 by Carlos Veira

It's finally here! It's been a pretty hard task because this new version represents a very important step forward not only in functionality but also in reliability.

As previous versions, documentation is something I must work on. Unfortunately, I don't have time to do it the way it should. But, I will be posting working samples, screenshots, and demo videos that will help on the training aspects of this tools.

Anyway, if you want to help with documentation or any other aspect, just let me know: I would love to build a team to make this project grow bigger and stronger.…

More on OpenSLIM and NMTools…

Published February 1, 2009 by Carlos Veira

Wow! What an intense week! It's being pretty hard to keep with regular postings. Obviously, working 12 hours a day doesn't help at all, but projects keep progressing successfully :D.

A new version of OpenSLIM and NMTools, v2.7b0, has been released last week. Version 2.8b0 is now on the way!. NMTools have reached a usable state thanks to a contribution from JJ who helped on resolving the last major issue. I am also introducing more Reports to the current OpenSLIM catalog; new UI for Contacts Management; some minor improvements on Tasks and Progress Management, etc.…

OpenSLIM & NMTools v2.6b0

Published January 18, 2009 by Carlos Veira

I still can't believe it… I will end my holidays with major milestones complete!

Of course, to ship is to choose, and there are details on this beta release that need further testing and may need to be fixed. This is specially true when we talk about NMTools, the newest piece on this little puzzle.

OpenSLIM is an MS Access application and I've been running its previous versions for the last 6 months. Currently, I am handling more than 1000 Nodes on more than 80 Services with it and, in my opinion, behaves fairly well.…
