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.

Not playing games: The GPU vs. CPU question gets more interesting
Putting thousands of cores to work makes perfect sense when you're powering a video game. But graphics processing units, or GPUs, can't serve much practical purpose in a corporate data center, can they?
The GPU vs. CPU discussion isn't as odd as it sounds. In fact, a more broad application of GPUs in the data center can provide the processing punch that CPUs simply cannot. With tasks where data can be processed in parallel rather than in sequence, GPUs might be a particularly valuable tool. The cover story in this issue of Modern Infrastructure looks at scenarios where simultaneous processing can be just what's needed, such as with machine learning and artificial intelligence.
This month's Modern Infrastructure also looks at how data can be protected while in the data center. Full encryption is seemingly a perfect defense for data theft. But that's a difficult -- and, to some, an unrealistic-- road to travel. We look at how an IT team can better safeguard its data, factoring in costs, the tools available and the tradeoffs involved in hack-proofing an organization's data.
And what about the vulnerabilities that arise from within your business? We examine the risk of data loss posed by the shadow IT phenomenon, an ongoing and ever-changing challenge.
It's clear that data is an increasingly valuable resource. Processing it and keeping it safe -- whether that entails taking up the question of GPU vs. CPU for certain workloads or upgrading encryption -- need to be priorities for IT professionals in organizations of all sizes and types.

Top cloud and data center technologies win Impact Awards
Plenty of data center technologies enter the market, aiming to solve this problem or that problem. (Or every problem, if the hype is to be believed.) But which products really hit the mark? Which ones stand out, coming along at just the right moment to address just the right need? Those are the kinds of products that garner attention in the annual Modern Infrastructure Impact Awards, and now is the time to name names. This issue unveils the 2017 Impact Award winners for the top cloud computing and data center technologies and services as selected by editors, independent experts and Modern Infrastructure readers. These participants assessed the tools they found worthy of recognition in categories ranging from best converged and hyper-converged product to best cloud migration and optimization offering to top systems management tool. To be eligible, a product needed to be either new to the market or substantially upgraded within the past year. And when the best of them distinguish themselves, that's when they warrant attention from the Modern Infrastructure awards.

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.

Container orchestration for a new breed of IT
PaaS offerings such as Heroku, RedHat OpenShift and Cloud Foundry have always used containers under the covers, but as containers move toward production use outside of PaaS in the cloud, they're being deployed in clusters of server infrastructure that are orchestrated to automate the deployment of containers. So is container orchestration right for IT? Well, that depends.
Beth Pariseau's feature this month, 'A New Day for PaaS' analyzes the way IT views PaaS, and how it's evolving. On the other hand, IT pros must dish out reality every once in a while to the business side, and often 'live on the edge' according to Alan Earls. But life on the edge can be dangerous, and it isn't just a figurative turn of phrase anymore, it's a physical location.

Container trends fuel storage needs
In life as in technology, there is no free lunch. We've seen this time and again. Every time a technology seems to be too good to be true, we do a little digging, and it turns out we were right.
Containers are just the latest example of a technology that IT must scrutinize. Sure, containers offer a ton of benefits -- density, portability and low-cost -- but what's the catch? Storage may very well be it.
And now that more IT organizations are "doing" DevOps, it's become clear that DevOps isn't some magic pixie dust whose mere mention makes everything right with the world. Meanwhile, over in the cloud, enterprises have learned that it's not all sunshine and roses. Notably, it's dawned on them that migrating legacy applications to an infrastructure as a service provider like AWS or Google Cloud Platform can be more trouble than it's worth.

Mad about microsegmentation
The tech industry seems fixated breaking things apart into ever-smaller units for greater levels of "granularity." Traditional standalone applications are maligned as "monoliths" that must be broken apart in to their component pieces, or "microservices." Broad brush security that covers an entire network is deemed insufficient, to be replaced by "microsegementation" -- applying security policies on a per-workload basis.
But breaking up is hard to do. In his story, "Mad About Microsegmentation," senior technology editor Stephen Bigelow lays out the pitfalls that will befall operators as they go down this road.
Breaking with tradition is hard too. For decades, one of IT's primary responsibilities has been to protect its systems from catastrophic failure by performing regular point-in-time backups that can get back to a known good state.

Windows workloads leap to cloud
Regardless of hype, there are quite a few areas where cloud remains very much a work in progress. Take cloud bursting. This has long been IT's holy grail for cloud -- the ability to seamlessly expand capacity constrained workloads to outside of your data center to meet unexpected demand. But while it sounds good on paper, it's not as easy as it sounds.
Running Windows rather than Linux in the cloud also hasn't been easy, but things are getting better. Technically, any infrastructure-as-a-service provider whose hypervisor exposes x86-based VMs should be able to run Windows.
Speaking of Windows, you'd think that Microsoft Azure would be a shoe-in with developers looking for an easy-to-use cloud platform. Based off our recent #Hashtag feature, however, it seems Azure has its fair share of discontented developers.

The merits of white box switching
Modern infrastructures are based on commodity, non-proprietary hardware. People have used commodity servers for a long time, but now we are seeing commodity switching gear too, on which we layer open network operating systems. This is a promising area, writes Ethan Banks in "Why White Box Switching?" An offshoot of software defined networking, "white box switching might survive on its own merits -- even if SDN falls by the wayside."
Modern infrastructures run on open source software, finds Ed Scannell in "Opening Up to Open Source." The reasons for today's surge of open source projects aren't the same as yesterday's -- whereas open source used to be about saving money, now it's about exploiting "the latest Web-based technologies for mobile, cloud and analytics platforms."
What makes one infrastructure "modern" and another not so much? That is continually up for debate, but there are definitely some common themes. Read on to learn more.

Collaboration moves beyond email
We have some nice examples of thinking out, not up, in this issue of Modern Infrastructure. Take data-aware storage -- a topic explored by contributing writer Alan R. Earls in "Not Your Average Disk Array." Conversations about data storage can be fairly predictable, centering on performance and capacity. Some storage vendors are stretching the bounds of traditional storage by leaning heavily on metadata and analytics, so as to give operators much more advanced management capabilities.
Then there's email. Given its shortcomings, a lot of people like to think, let's get rid of email altogether and just rely on new and exciting social messaging and collaboration tools. But that's impractical. In "Beyond Email," I talk to organizations augmenting existing email systems with complimentary tools that reduce our reliance on email, but don't throw the baby out with the bathwater.

Lift and shift vs. re-platforming cloud apps
When evaluating a new technology, some people like to go all in, with gusto, and adopt it hook line and sinker. Then there are folks whose MO is to take baby steps: Dip a toe in the water and do a lengthy proof of concept. What's right for any given organization depends on its temperament, needs, budget, skills -- any number of factors. One thing's for certain, there's no right answer.
This cover story in this issue of Modern Infrastructure delves into the different ways organizations implement cloud applications, whether replatforming or "lift and shift."
Sometimes, the question isn't how to implement this new technology, but whether to bother implementing it at all. "I'm a big believer in the natural balance that forms based on how people actually use things versus planning for how people might use things," Brian Madden said. So sit tight. What you need to do will become clear soon enough.

Can hyperconverged systems transform the enterprise?
It's hard to predict which novelties will become mainstays, and which will be has-beens. One current hot technology is hyperconvergence, the subject of Alex Barrett's article in our May issue, "The Hyperconvergence Effect." Is hyperconvergence a transformative approach to delivering IT, or just a nifty way of packaging compute and storage?
There are also many operational implications to a microservices route, says George Lawton: service discovery, network provisioning and release automation. Microservices has its challenges, but some say doing so can deliver significant ROI.
And virtualization has been transformative over the years, even as it's evolved. We've seen a shift away from hypervisor-based server virtualization to containers popularized by Docker. But it's hard to imagine a world without virtualization -- if only for the management and automation opportunities it brings to the table.

Container technology thrives for IT
Just when you thought you had driven the last nail in the coffin of old-school IT, you find out it's back -- albeit with a twist.
Remember operating system-level virtualization? This method of server virtualization is back with a vengeance as containers, with Docker leading the charge. But whereas the old-school containers were used largely by service providers to eke out every last drop of capacity from their server farm, today's containers are an application-portability play.
As for data center infrastructure, not only has the entire world not moved to public cloud, but many organizations use that consummate old-school IT model: the data center co-location facility.
Ethernet, meanwhile, never left the data center. Still, tomorrow's Ethernet doesn't look much like the Ethernet you know and love.
