Cloud computing types

Reading Time: 3 minutes

Cloud computing is a way to use (and also deliver) computing resources (for a formal definition see The NIST Definition of Cloud Computing).

For this reason there are different types of cloud based on which type of “computing” resources are provided. Mainly there are three big silos:

  • Infrastructure as a service (IaaS): usually it provides VMs a virtual datacenters resources (like storage and networking), and also the infrastucture need to manage them. An example of this kind of cloud is Amazon EC2.
  • Platform as a service (PaaS): in this case a developer platform is provided that usually include OS, libraries, programming language execution environment, and all that could be useful to provide multi-tiers application (included usually database, presentations servers, …). An example of this kind of cloud is Microsoft Azure.
  • Software as a service (SaaS): in the case a single application or service is provided (or a set of them). An example of this kind of cloud is Microsoft Office 365 or Google Apps.

With the term virtualization usually we are talking about System Virtualization, where a physical system is “partitioned” to permit multiple environments (using virtual machines).

But virtualization is more generic and include different types:

VMworld EU 2012: Why attend

12 September 2012

Reading Time: 2 minutes

The US edition is already finished, and there is less than a month to the European edition of VMworld 2012, this year (for the first time) at Barcelona (October 9-11).

The reasons to attend at this event could be similar to the reasons to attend at the VMworld US, plus of course the opportunity to visit Barcelona that this an awesome city!

In the European edition that is shorted (three days instead of four), there is also an addition day (on Monday) dedicated only for the VMware Partner, and this could be another reason (if you are an European partner and you cannot attend at the official Partner Exchange).

If you already have attend the VMworld US maybe there aren’t too much reasons (IMHO the two events are too close), but seems that other announces will be made during the europen event, so why not (at least one time) try to compare the two different edition on the same year?

I also hope that will confirmed also the 50% discount on each VMware exam, but actually it’s not listed on the special program page, and previous link refer only to the VMworld US. Was a great opportunity and Certification lounge was really cool at San Francisco. Discount has been confirmed and promotional code are VMWBAR50 for VCP exans and ADVBAR50 for VCAP.

VMware Hands on Labs

Everybody that has attend at least at one VMworld, or at a VMware Partner Exchange, event probably know what is a Hands on Labs (HoL) and probably has run at least a lab.

HoL are probably one of the best reason to attend at this kind of event (and also this year were really good) because you can make practice on VMware technologies, and also (in the recent years) are well designed to be scenario oriented (and usually scenarios could be really close to the real world).

The HoL infrastructure is really cool (and a good example of a cloud approach) and this year I’ve got also opportunity to ear more detail about it during a backstage (one of the best moment).

VMworld US 2012 report: best and worst

6 September 2012
Comments off
Reading Time: 2 minutes

Now that the VMworld US 2012 is over, I can can summarize what I’ve liked and what not in this big event.

The best moments and aspects where:

  • Networking with other people is (IMHO) the main reason to attend at this kind of event. Was a pleasure and an honor know new people and see again old friends.
  • VMware Office of the CTO event: great event with a lot of great people.
  • HoL Backstage: amazing and really interesting know how are made the HoL and also find how products are fit together (nice see that the monitoring part is mainly based on vCenter Operation Manager).
  • VCDX Appreciation Cocktail Party: lot of VCDX that I’ve never met before and a cool place.
  • VMUG Lunch: with an award to our Italian VMUG Leader! (see the picture)
  • VMTN Moderators Breakfast
  • vExpert Meeting with the two CEO and also the CTO of VMware
  • Keynotes (especially the second one) and follow them as press, with also a Press Kit!
  • San Francisco itself!

Not so bad, but also not so good:

  • Jon Bon Jovi performance: too much cover and too few historical songs.
  • Location: Maybe too big and too much shift between the campus. And some places were not well signed in the map (like the certification or the partner lounge)
  • Information: as written before, some (but just few) were not well described
  • Sessions: some where very good, other maybe not so technical as the usual level in the European edition

Worst moments and aspects:

  • Hotels where quite expensive at San Francisco!
  • The food wasn’t not comparable with the European editions: always cold food, few options (more limited for vegetarian/vegan/…)
