OpenStack in a day for under $20

One of the hardest things with OpenStack can be just getting started, especially in the enterprise. Acquiring hardware and getting the right networking in place can require a monumental effort. And, while you can use DevStack and virtual machines (VMs), the result isn’t really useful for a proof of concept or demo environment. SoftLayer, an […]

Bare metal vs. virtual machine cloud: Which option is right for me?

There is no doubt that cloud brings us an entire new set of value propositions for enterprise computing environments, offering a huge set of benefits like application scalability, operational flexibility, improved economies of scale, reduced costs, resource efficiencies, agility improvement and more. It is harder to find all these benefits when considering just the traditional […]

Cloud Computing Reference Architecture (CCRA): A blueprint for your cloud

Leading technology innovation happens in multiple environments—from university research labs to Silicon Valley startups to customers who push the limits of technology to adapt to their business models. Innovation can even happen in government. The National Institute of Standards and Technology (NIST) took an early leadership role in standardizing the definitions around cloud computing. This happened just as […]

How to find the right balance between scale up and scale out in cloud

Cloud computing provides the elasticity to scale infrastructure on demand. Applications with a dynamic workload demand get application programming interface (API) driven access to a flexible infrastructure to meet performance guarantees and minimize resource costs.

What is Hadoop, and how does it relate to cloud?

With all the recent buzz around Hadoop, you may be asking, “What is Hadoop and what does it have to do with cloud?” Before I answer this, we should discuss big data. Big data: More than just analytics Analytics provides an approach to decision making through the application of statistics, programming and research to discern patterns […]

How to explain vertical and horizontal scaling in the cloud

In this world of cloud, one of the biggest features is the ability to scale. There are different ways to accomplish scaling, which is a transformation that enlarges or diminishes. One is vertical scaling and the other is horizontal scaling. What is the difference between the two? If you look at just the definitions of […]

5 considerations when choosing between a SaaS or on-premises

Adoption of software as a service (SaaS) is accelerating and many organizations are realizing the transformative benefits. A recent IBM study highlighted how leading organizations (Pacesetters) are leveraging SaaS deployments to unlock benefits such as reduced total cost of ownership (TCO), increased enterprise collaboration and enhanced market agility. Enterprise software vendors are realizing that deployment […]

What is software as a service (SaaS)?

Even if you’ve never heard the term software as a service (SaaS) before, you know what it is already. You’re using it right now, and I’d wager that you have at least a couple of other software as a service programs open in another tab (or another window). It’s everything from Google search to Facebook […]

What is platform as a service (PaaS)?

To answer the question, “What is PaaS?” let’s start with a basic definition: Platform as a service (PaaS) is a cloud-based computing environment designed to support the rapid development, running and management of applications. It is integrated and abstracted from the lower-level infrastructure components. For a more offical version, you can click here for the […]

What is infrastructure as a service (IaaS)?

What is IaaS? It seems like a simple, innocuous question. However, as with most technical topics, things are never as they appear. IaaS is no different. To illustrate this, I reached out to four IBM cloud leaders and posed that simple question. What I got back were answers heavily influenced by their world view—where they came […]

Top five advantages of software as a service (SaaS)

Software as a service (SaaS) is an alternative to the standard software installation in the business environment (traditional model) where a user has to build the server, install the application and configure it. In SaaS, the user does not pay for the software itself. Instead, it works like a rental. They have the authorization to […]

What is mobile cloud computing?

We have been observing some significant technology trends for the last few years. Cloud computing and mobile are two such things. Widespread adoption of these two is changing our lives, the way we do business and most of our day-to-day dealings. The domain of systems of engagement is getting bigger and bigger. It is no […]
