Is That IaaS or Just Really Good Virtualization?

first_imgI was recently pulled into a Twitter conversation that spawned off a blog post Paul Galjan made concerning Microsoft Azure Stack IaaS and its use cases in which he correctly pointed out that Azure Stack is not just a VM dispenser.  The question was posed as to what exactly constitutes IaaS vs. virtualization (VM dispenser) and where does each fit into the hierarchy of “cloud”?Let’s start out by clearly defining our terms:Virtualization in its simplest form is leveraging software to abstract the physical hardware from the guest operating system(s) that run on top of it.  Whether we are using VMWare, XenServer, Hyper-V, or another hypervisor, from a conceptual standpoint they serve the same function.In Enterprise use cases, virtualization in and of itself is only part of the solution. Typically, there are significant management and orchestration tools built around virtualized environments. Great examples of these are VMware’s vRealize Suite and Microsoft’s System Center, which allow IT organizations to manage and automate their virtualization environments. But does a hypervisor combined with a robust set of tools an IaaS offering make?IaaS. Let’s now take a look at what comprises Infrastructure as a Service.  IaaS is one of the service models for cloud computing, and it is just that – a service model.  NIST lays it out as follows:The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls).You may be looking at that definition and asking yourself, “So, based on that, virtualization with a robust set of management tools is capable of delivering just that, right?” Well, sort of, but not really. We must take into account that the service model definition must also jive with the broadly accepted “Essential Characteristics” of Cloud computing.On-demand self-serviceBroad network accessResource poolingRapid elasticityMeasured serviceEssentially all of these core tenets of “cloud” are capabilities that must be built out on top of existing virtualization and management techniques.  IaaS (as well as PaaS for that matter) caters to DevOps workflows enabling Agile code development, testing and packaging, along with release and configuration management, without regard for the underlying infrastructure components. This is clearly not the same as virtualization or even “advanced virtualization” (a term I hear thrown around every so often).So then how does that relate back to the conversation concerning Azure Stack IaaS and VM dispensers? For that we need to look at how it plays out in the data center.Building a virtualization environment has really become table stakes as a core IT function in the Enterprise space.  There are plenty of “DIY” environments in the wild and increasingly over the past few years we’ve seen platforms in the form of converged and hyper-converged offerings that streamline virtualization efforts into a turnkey appliance for hosting highly efficient virtualized environments – Dell EMC’s VxBlock, VxRack, and VxRail being leaders in this market.  That said they are not “IaaS” in a box – they are in essence, and by no means do I intend this as derogatory, “VM dispensers,” albeit highly advanced ones.For customers that want to move beyond “advanced virtualization” techniques and truly embrace cloud computing there are likewise several possibilities.  DIY projects are certainly plausible though they have an extremely high rate of failure – setting up, managing, and maintaining home grown cloud environments isn’t easy and the skill sets required aren’t cheap or inconsequential.  There are offerings such as Dell EMC’s Enterprise Hybrid Cloud which build on top of our converged and hyper-converged platform offerings, building out the core capabilities that make cloud, cloud.  For customers that are fundamentally concerned with delivery of IaaS services on-premises that can be delivered from a standardized platform managed and supported as a single unit, Enterprise Hybrid Cloud is a robust and capable cloud.So, what about something like the Dell EMC Cloud for Microsoft Azure Stack?  In this case, it’s all about intended use case. First let’s understand that the core use cases for Azure Stack are PaaS related – the end goal is to deliver Azure PaaS services in an on-prem/hybrid fashion. That said, Azure Stack also has the capability to deliver Azure consistent IaaS services as well.  If your organization has a requirement or desire to deliver Azure based IaaS on-prem with a consistent “infrastructure as code” code base for deployment and management – Stack’s your huckleberry.  What it is not is a replacement for your existing virtualization solutions.  As an example, even in an all-Microsoft scenario there are capabilities and features that a Hyper-V/System Center-based solution can provide in terms of resiliency and performance that Azure Stack doesn’t provide.In short – virtualization, even really, really, good virtualization, isn’t IaaS and it’s not even cloud.  It’s a mechanism for IT consolidation and efficiency. IaaS on the other hand builds on top of virtualization technologies and is focused on streamlining DevOps processes for rapid delivery of software and business results by proxy.In scenarios where delivery of IaaS in a hybrid, Azure-consistent fashion is the requirement, Azure Stack is an incredibly transformative IaaS offering.  If Azure consistency is not a requirement, there are other potential solutions in the forms of either virtualization or on-prem based IaaS offerings that may well be a better fit for your organization.last_img read more

The Most Pressing Data Concern in 2019

first_imgAround this time every year, I always see an influx of the top trends in technology. It seems like the perennial hot topic is security, with good reason as each year the number of incidents and evolving creativity with which these attacks are orchestrated contribute to an increase in the sheer magnitude of losses.Every year there are new technologies that capture attention from network-based monitoring to artificial intelligence to increased threat detection for instance. Recently though, there’s been another trend that has cropped up, that has nothing to do with deploying a technology designed at mitigating cybersecurity issues, and that is risk insurance. Increasingly organizations are buying blanket policies that cover their liabilities, but do these actually protect your business? Sure, they might cover the expenses due to a failure to comply with regulatory requirements, or address lawsuit exposure but they don’t actually protect and, more importantly, recover your most critical asset: the data itself.We have transitioned to a time where every organization is now a technology company. It is a time where the most significant source of differentiation is often the data an organization keeps. It is in this world where data protection is so critical to the continued success of a digital business. It is also an area where many organizations struggle to find their footing and are often left exposed to substantial risk of data loss and downtime.Why is it so hard to get data protection right?Complexity: Data is now spread across the globe and on numerous platforms. Multi-cloud is the norm. Data platforms have become specialized to address specific workloads further creating a balkanization of the data landscape. All this makes it difficult, albeit nearly impossible, to maintain a data protection solution that spans the entire data footprint.Massive Data Growth: It isn’t uncommon for data to grow 50-80% year over year. As it keeps proliferating, that creates more and more challenges for backup and data retention. For organizations that value data, the need to retain more of it, and for longer become driving concerns.Increased Magnitude of an Event: As data becomes more prolific in its use across the organization the associated cost of downtime or data loss becomes magnified, forcing requirements for increased expectations on the protection solution since data must be available and recoverable as fast as possible.Further complicating things is that these challenges compound. They create tighter backup windows, more network bandwidth usage, require larger backup capacity, and cast a heavy burden on IT to maintain it all.Data Management Increasingly Becoming KeyIt is in this world that we must rethink data protection. Protecting data isn’t only about keeping it, now it requires continuous availability to be relevant. Data protection technologies can be used in new ways to accelerate migrations, power DevOps activities, simplify compliance and regulatory requirements, and facilitate the preservation of data for long-term monetization.By leveraging the Dell EMC Data Protection portfolio, you can simplify your data landscape by achieving coverage across heterogeneous and multi-cloud environments using flexible solutions that include software, integrated appliances, and target appliances. Additionally, we help reduce the amount of storage required by achieving data reduction rates up to 55:1 in a scalable easy to manage solution that meets your growing businesses’ needs. Finally, when events do occur, we can help you to mitigate the damage by providing up to a 10x faster recovery for mission-critical applications.More Than an Insurance PolicyAs I noted the idea of buying insurance to cover cyber incidents has become increasingly common and given the risks that are in this world, that course of action may be prudent. But it is time to take a critical look at the preparedness of the organization to address incidents more holistically. Data protection will be one of the most critical investment opportunities organizations have as they go digital. Organizations who make a corresponding investment won’t merely be safeguarding their data but also extending its value over time. This is my bold prediction for 2019, and that is the foundation for the work we are doing.Dell EMC has always been one of the most trusted names in data and in a world that runs on data capital we are increasingly looking at ways to help you protect this valuable asset.Learn more about Dell EMC Data Protection Solutionslast_img read more

Broken by Trump, US refugee program aims to return stronger

first_imgPresident Joe Biden has vowed to restore America’s place as a world leader in offering sanctuary to the oppressed by raising the cap on the number of refugees allowed in each year. He wants to raise admissions to 125,000 from the Trump administration’s record low of 15,000. But advocates say it will take much more to reestablish the pipeline. The Trump administration added layers of obstacles, including cutting jobs or reassigning those who interview and process refugee applications. It’s left a backlog of tens of thousands of cases. Advocates are pushing Biden for reforms that would shield the program from political swings in the future.last_img read more

Brazil’s Vale signs $7 billion settlement in mining disaster

first_imgRIO DE JANEIRO (AP) — Brazilian mining giant Vale signed a settlement deal on Thursday to pay 37.7 billion reais ($7 billion) to the state of Minas Gerais, two years after a dam rupture in the city of Brumadinho killed more than 270 people. The settlement signed Thursday will compensate families of victims and fund projects in Brumadinho and throughout the state. The collapse of a dam at Vale’s iron ore mining complex in January 2019 had unleashed a destructive torrent of mining waste, burying the equivalent of 300 soccer pitches under thick mud. Authorities say 11 people are still missing.last_img read more
