A serverless architecture could live in your data center

Just because you don't see the server doesn't mean it's not there. Serverless frameworks are superseding containers, but is the extra abstraction worth it? Continue Reading

Machine learning algorithms make life easier -- until they don't

Algorithms govern many facets of our lives. But imperfect logic and data sets can make results worse instead of better, so it behooves all of us to think like data scientists. Continue Reading

When the big cloud infrastructure providers aren't the right fit

When a business chooses one of the major providers for its cloud services, there shouldn't be a lot of surprises. You do your homework, consider the available services, select instance types, compare costs and then make a decision. At that point, you should know what you are getting. But what if you don't want what you're getting?

There are scenarios where a business seeks out the services of one of the specialty cloud infrastructure providers. These niche providers compete against behemoths such as Amazon Web Services, Microsoft Azure and Google Cloud Platform, but not by trying to match them service for service. Nor can they keep pace on price. Instead, these smaller providers focus on particular niches, trying to offer specialized services, customer care and flexibility that the hyperscale providers may struggle to furnish.

The cover story for this issue of Modern Infrastructure delves into the reasons a business might choose a niche player instead of one of the major cloud infrastructure providers. TechTarget's Kristin Knapp reports on how these situations arise and how businesses respond. The right fit, she finds, might not always be found in one of the expected places.

Staring down the security issues in cloud computing

Adoption of cloud computing has no doubt been slowed by worries about the security of those out-of-sight servers and resources. While reasonable, those worries have given way over time to acceptance and even optimism.

In this month's Modern Infrastructure cover story, TechTarget’s Trevor Jones writes about why security issues in cloud computing are not the impediment to adoption that they once were. In fact, some organizations are coming to the conclusion that their workloads run more securely in a public cloud than in an on-premises environment. Cloud service providers possess security expertise and experience at levels that aren’t as readily available on a typical IT staff, and certifications give confidence that providers can actually do all they claim to do.

The public cloud is not a risky place to do business, though its safeguards are different from those you've put in place to protect your own data center. These differences are most clearly seen when looking at the shared-responsibility model, which addresses many of the security issues in cloud computing. Users and providers must each do their part. Otherwise, the risks will become apparent, and cloud computing won't be what you need it to be.

This issue also looks at how a new wave of products in development brings memory and storage technologies closer together. Nonvolatile dual-inline memory modules, for example, combine the speed of memory with the persistent qualities of storage in some interesting ways. Also included is an article on how some IT shops that have adopted flash storage are simultaneously impressed and disappointed with the results. Costly flash products invariably improve performance, but they won't solve every problem or clear every bottleneck.

Application support and maintenance add up to operational ALM

OpenStack infrastructure turns to containers

OpenStack is far from perfect. In fact, there are a number of hurdles it needs to clear before widespread adoption in the enterprise becomes a reality. However, a recent technology trend might just be what the OpenStack infrastructure needs, and it's one that many originally thought would be OpenStack's death sentence -- containers.

A recent study from OpenStack's user survey showed that containers generated the most interest among the community, a sign that IT is ready to take the leap from virtualization to containers. OpenStack leaders say containers are the central piece to the underlying cloud framework that OpenStack lives on.

Meanwhile, data analytics continues to drive the next wave of IT ops tools by combining input from various platforms to create predictive information for the enterprise. So where does IT go from here? Read on to find out.
