  1. Why Companies Succeed — and Fail — With Containers

    Although containers (the virtual kind) have been around awhile, it still feels like they’re brand new. Contrast that with virtual machines, which have been in common usage for 15 years now. Will containers one day seem as mainstream as virtual machines? It’s hard to say, but there’s certainly a lot of momentum in that direction. Red Hat has been in the container business for about five… Read More

  2. Good DevOps, Part 3: Continuous Delivery and Deployment

    In the second blog in this series on DevOps, you’ve learned what continuous integration (CI) is and how it benefits an organization. The ability to commit code and have it built in a centralized location that all developers are committing to is the key to getting the code ready to use. But CI is just the beginning. How do you deploy the software to perform further testing, and finally deploy… Read More

  3. Good DevOps, Part 2: Continuous Integration

    So you’ve got all of your code stored in GitHub or some other source control system. That’s a great first step! But now you have another problem: you and your team have to remember to kick off some other routines once new code is checked in. You may have to run tests on that code and launch a build process that compiles the code, creates an artifact, and performs other mandatory tasks to get t… Read More

  4. Good DevOps, Part 1: Take Your Time

    Continuously delivering value to end users, the business, and the rest of the teams inside an organization has always been crucial. But why are we hearing about it so much now? What is this whole DevOps thing, and why put “continuous” in front of so many words? DevOps, and its set of continuous processes called continuous integration, continuous delivery and continuous deployment, are hot.… Read More

  5. What’s the Future of Java and Other Java Virtual Machine Languages?

    Among the many innovations Java introduced was the exposure of its internal byte code, or “virtual machine.” Many languages by then (1995) were converted or compiled into some intermediate format before being assembled into native machine code, but Java’s designers placed this virtual machine at the center of the Java development process by distributing programs in that form—all in the cau… Read More

  6. Branch Maintenance via Out-of-Band Management

    Out-of-band management, aka OOBM, plays a vital role in modern IT operations of all sizes and scales. Indeed, OOBM might be judged “mission critical” for headquarters operations and data centers alike. But OOBM is tremendously important for satellite IT operations, as well, most notably for branch and remote offices. Such operations span a wide range of locations and roles, with tens to hun… Read More

  7. Stay Connected with Out-of-Band Management

    During a security assessment, auditors always ask this one question: “How do you manage your devices?” The answer should be: “out-of-band management.” Is that your answer? If not, you may have issues that need immediate attention. What Is Out-of-Band Management? Let’s get started with a definition. Out-of-band management, or OOBM, is a technology that allows you to connect to devi… Read More

  8. Systems Management and the FCAPS Standard

    Managing systems and networks ultimately means understanding what they comprise, what they can do, and who’s allowed to use them. In IT, systems and network management is an important discipline with a long history, with many approaches and tools to implement them. FCAPS Sets the Management Stage A comprehensive model for network and device management appeared in the 1980s as part of the Ope… Read More

  9. Tips for Proper Out-of-Band Network Design

    Out-of-band (OOB) networking provides a separate, independent pathway in and out of systems and networks. OOB doesn’t depend on production networks to access equipment, perform management and monitoring tasks, make repairs, or access data for legal or technical reasons. But what’s the proper way to set up an OOB network? Do you know and understand how they differ from standard networks? If… Read More

  10. SASE: Rethinking Network Security in the Age of the Globally Distributed Cloud

    Today's network security solutions are proving inadequate, based on a major shift in the spotlight on where data and resources are located and work is performed in the enterprise network. With the increase in remote-based users, Software-as-a-Service (SaaS), and globally distributed cloud services, the focus of identification has changed from the data center to the user or device. This isn't yo… Read More

  11. The 'Three E's' of Exceptional IT Content

    In my work the last few years, I’ve overseen the creation of content that helps IT vendors connect with information-hungry IT buyers. I’ve been observing how that content is received and find the '3 E’s' mnemonic a helpful way to remember each ingredient. I’m constantly teaching my team (and the army of contributors we work with) to think about these things. Here they are... Read More

  12. Where to Spend on IT Content Marketing in 2020

    We polled our audience to find out how they feel about the standard stable of IT marketing tactics and assets. The overwhelming feedback we received reveals six key areas we recommend that our clients invest in, and three that are little more iffy in terms of bottom-line results. Read More

  13. How Impactful Is VMware’s New Core-Limited Licensing?

    This week, VMware announced new licensing restrictions for vSphere, which I wrote about here.  I wanted to get more understanding for how impactful this change would be for existing customers.  On today’s ActualTech Media EcoCast, I asked our audience for two pieces of information.  The first asked viewers if they have any servers with individual processors of more than 32 cores.  The second… Read More

  14. VMware’s Licensing Change Redux: Better the Second Time Around

    The year was 2011. I was comfortably ensconced in my office at Westminster College watching as VMware brought out a marketing executive to discuss the company’s revolutionary new licensing program. As soon as I saw that it was a marketing person giving the news about a change in licensing, I thought to myself, “This isn’t going to be a positive announcement.” And it wasn’t. vSphere… Read More

  15. Report: Cloud Spend Tops Data Center Spend for First Time in 2019

    “Trend” stories have some value, in the same way virtual machine snapshots have some value: they’re helpful, and often quite helpful, as long as you understand their limitations. (And always remember: a snapshot is not a backup!) You know the end-of-year trend articles: “Top Stories of 2019,” “Most Downloaded Songs of 2019,” and so on. They provide a look at what happened in the p… Read More

  16. Google Anthos: Kubernetes the Easy Way

    Kubernetes continues to gain popularity in the industry, and shows no signs of slowing down. This container management platform has essentially won the container wars, and is now the de facto orchestration tool for containers. Kubernetes is popular because managing containers is a serious pain. But Kubernetes itself is a pain, too—ask any admin who’s tried to bootstrap it. In fact, the most… Read More

  17. WannaCry Ransomware Hits Hard in 2019

    If your organization was pummeled by the WannaCry virus last year, you’re not alone: nearly a quarter of all ransomware attacks were of that variety. And the damage it did was staggering. That’s according to PreciseSecurity.com, which reported that WannaCry was the most common crypto ransomware attack of 2019, accounting for 23.56% of all such assaults globally. The article also estimate… Read More

  18. Challenges to Cloud Computing Resource Planning

    Cloud computing has transformed how enterprises think about infrastructure. A decade ago, IT professionals had to make server projections months or years in advance, deciding on the types of servers they’d need. That would in turn be largely determined by the services required for their business needs, and expected loads those servers would bear. Cloud computing has changed the game. Enterpri… Read More

  19. ‘The Cloud’ Is No Magic Bullet

    There remains a belief among some in IT that moving to “the cloud” will solve all their problems. This is, emphatically, not the case. It’s entirely true that the cloud has massive advantages in terms of things like the ability to scale, to move capital expenditure (CapEx) costs to a more budget-friendly operational expenditure (OpEx) cost model, and faster time to market via containers.… Read More

  20. 5 Big Challenges of Multi-Cloud Management

    Cloud computing is ubiquitous. Enterprises are continuing to move to the cloud in record numbers. According to the RightScale 2019 State of the Cloud report, 91% use some form of cloud, and 84% of enterprises have a multi-cloud strategy. It's easy to see why: a multi-cloud architecture, comprised of different cloud platforms, offers the versatility to accommodate a wide range of enterprise computi… Read More
