Coffee As A Service – A Better way to understand the “?aaS” paradigm

I have a hard time keeping all the cloud terms straight.  Everything seems to be available As A Service (aaS).  Try as I might to explain them, it just didn’t click for some people.  Since cloud terms are so nebulous some times, I decided I need to put everything in a context that people understand.  Therefore, I present…Coffee as a Service (CaaS):
Software as a Service (SaaS): Anytime you want coffee, it just appears in front of you.  You don’t have to make it or anything.  Sometimes it shows up immediately.  Other times it shows up an hour or so after you wanted it.  You pay a monthly fee, but if you want to have cream or sugar you have to pay a bit more.  Some SaaS coffee vendors don’t have those options, so you’re stuck with whatever you get up front.
Platform as a Service (PaaS): You’ve decided that you want to have coffee, but you want a bit more control over it.  You sign up for a new service that gives you coffee packages.  Dark roast, light roast, and Turkish coffee are all options.  You are still at the mercy of the provider for other options like latte or cappuccino.  It is still mysteriously delivered to you.  Cream and sugar are options in each of the packages for a small fee.  Coffee can still show up late, but you have an agreement with the provider that late coffee gets you a small amount off the monthly bill.
Infrastructure as a service (Iaas): You’ve now decided that you want complete control over your coffee delivery.  You’ve contacted a new provider that is willing to rent you a coffee machine with all the extra hardware needed to make any kind of coffee you want.  You’re going to have to buy your own coffee and creamer and sugar.  Once you have it at the coffee machine, they’ll make the coffee to your exact specifications and send it to you.  Might still show up late depending on how popular the service is or if some technician accidentally restarts the machine on a Friday night.  You get charged either by the cup or by how often the machine is used.  Coffee still tastes okay but you have to worry about renting more machines as it becomes more popular.  Machine rental rates fluctuate if you use the Spot Machine market.
Private Cloud: Okay, forget about the whole renting thing.  Time to go to the coffee warehouse and buy everything yourself.  You max out your credit card, but you come home with a coffee machine and a milk steamer.  You still provide everything yourself.  You find a place to hook everything up with electricity and water supply.  You grind the beans yourself.  You make your own coffee or you hire a barista to do it for you.  The coffee is excellent and on time.  Your credit card bill scares the daylights out of you.  In three years, you have to upgrade your coffee machine again to support hyper foaming milk.
Hybrid Cloud: You can make the basics with your machine.  You still can’t figure out how to make a good cappuccino.  All the easy stuff gets made locally by you or your barista.  For the really odd stuff, like double shot mocha light frappuccinos you send people to the Starbucks down the road.
Cloudbursting: Your fancy coffee machine is really popular around the office.  About once a month, there’s a line that’s 50 people long.  Rather than making them wait for their coffee, you pass out Starbucks gift cards for anyone over the 35th person.  You send them off to get their coffee.  You can justify the gift card cost because you’re only busy that one time a month.
Thanks verymuch to the Author for bringing out this.

“Lumira” is the new name of SAP Visual Intelligence

Hello Folks!

SAP really is pushing hard on this cloud thing. Days after the German business software giant announced plans to put its HANA in-memory database into the cloud, it has done the same with its Visual Intelligence product, now renamed “Lumira” (SAP dearly loves renaming its products, and this time it’s gone for “a more human-friendly yet Google-ready name”).

Here is more to read on this:*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_*1_nav*4responsive*4tab*4profile_*1

Trying to implement SAP Systems on HANA ? Here are some Excellent Resources/Readings/Knowledgebases

In my current Job profile, I interact with a lot of Professionals (within and outside my organization) who are either having incomplete information, or having NO information about “Implementing SAP Applications on HANA”. Being a new subject/product/application.system, it takes a lot of time for people to build trust over HANA. And I am not saying that there are no proof points to build trust on, but it seems Implementation resources are pretty less.

It helped me immensely when I followed these Cookbooks with respect to having SAP Applications running on HANA. Have a look:




There are various Implementation Resources, found here: which you’ll find helpful.

Applications like BPC, BOBJ, etc. are pretty more self explanatory and moreover there are lots of documentation on

As it helped me, I am sure it will at least give you right directions towards your Implementations.

Do comment if there is more information you think I should add here, and I will definitely improvise.
