The IaaS Rush

 

Why is everybody getting into the IaaS business? For a long time, it was only Amazon, then Rackspace, Savvis etc followed but there were no new significant players for a long time. However, most recently, IaaS has been really hot; the new entrants into this space are Google, Microsoft and HP. While Amazon, Rackspace, Savvis have predominantly been operating in the IaaS space, Google was more of a PaaS and SaaS player. It did a little bit on the IaaS side with Google drive but nothing to the extent of Amazon S3. Microsoft was also a platform player with Azure, but recently introduced an IaaS offering into Azure. For HP, it was a brand new entry into the Cloud Space. While I am not sure about what technology Google is using to power its IaaS (should most probably be something based on Xen or KVM), HP’s IaaS management layer is run on OpenStack with probably Xen as the Virtualization layer.

Enterprise Clouds and Swiss Cheese

 
 The cloud is a very complex machine with lots of moving parts. The whirring and humming of modern data centers are caused by fans, air conditioners and power converters, but the “moving” parts are in fact pieces of solid state deep inside the cloud. We are referring to the huge number of software-controlled virtual components that work together to create the computing environment that we know as the cloud.

Computing clouds have become some of the biggest and most complex machines ever made by man. For every physical component in a cloud, there are easily 10 virtualized components corresponding to all layers where virtualization is present - including storage, networks, CPU, memory, operating systems and even applications. The entire set can easily run into the hundreds of thousands of components in an enterprise cloud, and tens of millions in a public cloud. By way of comparison, the space shuttle had 2.5 million parts1...

Going for Gold in the Olympic IT Infrastructure Event

Going for Gold in the Olympic IT Infrastructure Event

 

The countdown is on - we're less than a month away from the London Olympics. While many are getting excited to watch their countries compete, there's a group of people outside of the Games that are getting ready for their own competition of sorts. Nope, it has nothing to do with swimming or gymnastics, this new event is called the Internet crawl. Who's competing? Anyone that has a business or is does business in London, whose cash flow relies heavily on Internet transactions. Thankfully, for this event multiple companies can share the podium. All they have to do to achieve gold is figure out a way to avoid having their services go down.

Think about this: Over 20 million tickets have already been sold for the Games. On top of that, there will be thousands upon thousands of world news and sports media in attendance. Combined, that equals a massive amount of smartphones, tablets and laptops churning out tweets and posting pictures, over and above the massive data volumes already generated daily by citizens of the U.K.

Cloud Services & Consumerization Driving Competition with Internal IT

 

There are two market forces that are fundamentally changing the nature of enterprise application delivery and consumption:

  1. delivery of enterprise applications as a service via the cloud
  2. the rapid shift of accessing enterprise applications on mobile devices

IT organizations are facing stiff competition from Software as a Service (SaaS) and cloud providers who are delivering enterprise applications as a service that are faster, cheaper and accessible anywhere, on any device.

IBM Smartcloud Infrastructure - Build your private and hybrid cloud computing environment

Cloud computing is quickly becoming the standard. The convenience and power afforded by cloud computing has helped millions of businesses, organizations, and individuals to build up very impressive computing systems, the likes of which were once the exclusive domain of much larger and richer entities. What the cloud enables is access to all the latest advances in computer technologies available, as well as the power of virtualization and connectivity.
 
As Clear as Day
 
The intelligence and convenience cloud computing are completely obvious once you start using it for yourself. “The Cloud” has several different definitions and connotations, as well as several different firms offering themselves as the alpha and omega when it comes to getting you together with the cloud. But there are few if any with the institutional knowledge and talent of IBM Smartcloud.

Are You Up to Date? Today’s Top Five Security Threats to Your Data

 
If you’re feeling a little paranoid about data security threats, you can relax. You’re not paranoid! The threats are real. While financial institutions have gotten smarter (the recent breach at Global Payments notwithstanding), companies in other industries, such as retail and hospitality, are now in the crosshairs, and hackers and scammers are finding easier prey in small to medium businesses.
 
According to the Verizon Business report, “2012 Data Breach Investigations,” last year saw the second-highest data loss total since the company started keeping track in 2004. Some 855 incidents resulted in 174 million compromised records.
 

Cloud On-Boarding - The True Story

Cloud On-Boarding - The True Story

 
 
Everyone wants to be in the cloud. Organizations have internalized the notion and have plans in place to migrate their applications to the cloud in the immediate future. According to Cisco’s recent global cloud survey:

Presently, only 5 percent of IT decision makers have been able to migrate at least half of their total applications to the cloud. By the end of 2012, that number is expected to significantly rise, as one in five (20 percent) will have deployed over half of their total applications to the cloud.

But that survey also reveals the fact that on-boarding your application to the cloud “is harder, and it takes longer than many thought”, as David Linthicum said in his excellent blog post summarizing the above Cisco survey. Taking standard enterprise applications that were designed to run in the data center and on-boarding them to the cloud is in essence a reincarnation of the well-known challenge of platform-migration, which is never easy. But why is there a sense of extra difficulty in on-boarding to the cloud? The first reason David identifies for the extra difficulty is the misconception that cloud is a “silver bullet”. Such “silver bullet” misconception can lead to lack of proper design of the system, which may result in application outage, as I outlined in my previous blogs. Another reason David states for the extra difficulty is the lack of well-defined process and best practices for on-boarding applications to the cloud:

Is All Virtualization Destined for the Cloud?

 
 
It seems that the message to the millions of virtualization users is that if you are not either working in a cloud environment or moving to a cloud environment, you are behind or you have yet to be enlightened.
 
Vendors, press and analysts publish maturity curves that often show the progression through which IT professionals should be moving to achieve cloud enlightenment. Often, the typical virtualization user would be in the “immature” portion of these maturity curves with a long road ahead of them before they get to cloud “nirvana”.

Illuminating the Cloud for Increased ROI

 
Whenever I speak with CIOs and IT professionals about the benefits of cloud computing, I encounter a wide range of responses – from enthusiasm, to guarded optimism, to even outright skepticism.
 
While it’s clear that the cloud is playing an increasingly central role in IT, both the opportunities and challenges inherent therein, can be tricky to navigate. This has created a situation where efficient and economical use of the cloud is not all that common.
 
By clarifying some of the major issues swirling around cloud computing, I hope to equip the business community with knowledge and insight that will allow them to better maximize their IT investments.
