Docker offers big opportunity for software-defined networking

Recently, technologies like Docker have popularized software containers as basic computational units for application deployment. In addition to easing the process of application development, testing, deployment and maintenance, these technologies also promise to be lighter-weight alternatives to full-fledged virtualization.

5 technologies every cloud-ready systems administrator should know

In the last week of June 2014, I had the chance to share a project with worldwide information technology (IT) experts—all of them with a wide breadth of experience in the IT industry. We discussed several topics during those days—of course each expert has a very particular and personal point of view about the market […]

Bare metal vs. virtual servers: Which choice is right for you?

Before thinking about servers, imagine you need to practice for a triathlon. You probably need appropriate equipment and clothing. In terms of your IT workloads, it is pretty much the same. You need the appropriate server for the best performance. Cloud providers in the market may make some assumptions about all resources in the cloud […]

Year One: An interview with SoftLayer CEO Lance Crosby

In the year since IBM acquired SoftLayer, Lance Crosby has been in almost perpetual motion. He has circled the globe touting IBM’s lofty cloud ambitions, while overseeing SoftLayer’s expanding capabilities and integration with the rest of IBM’s cloud offerings. But before the expansion could occur, there was a decision that had to be made, challenges […]

The key differentiators of Docker technology

Without a doubt, Docker is emerging as a next-generation image building and management solution. As widely known, one of the largest objections to the “golden image” model is that we end up with image sprawl: large numbers of (deployed) complex images in varying states of versioning. It is a common concern expressed that images also […]

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 […]
