I've been asked several times recently about the difference between Verification and Validation in automated testing and for some advice on applying and documenting each kind of testing. Let me first take a minute to define these terms.
Verification is testing that your product meets the specifications / requirements you have written. "Did I build what I said I would?"
Aristotle (384 – 322 BC) is credited as the first person to classify our five sense organs: sight, smell, taste, touch, and hearing and Immanuel Kant, a famous philosopher from the 1700s said that our knowledge of the outside world depends on our modes of perception. Our highly developed organs of the eyes, ears, nose, tongue and the skin on your hand provide the sensing equipment necessary to send that information to the brain. In some cases, one of the sensors might not work properly in the case of the blind or deaf, yet the four other senses are heightened and exceed normal operation to mak...
In case you missed it, the first phase of cloud computing has left the building. Thousands of companies are in the cloud. Practically all organizations regardless of size already have production applications in a public, off-premises cloud or a private cloud. Yep. Been there, done that.
And the vast majority of these applications use the classic “SaaS-style” public cloud model. Someone develops a useful service and hosts it on Amazon Web Services (AWS), Microsoft Azure, IBM Cloud Marketplace, Google Cloud Platform (GCP) or one of several other cloud vendors. Accessing this external service ...
Converged infrastructure solutions are hastening the path to big-data business value and cloud deployment options.
We'll also delve into how the right balance between open-source and commercial IT products helps in creating a big-data capability, and we'll further explore how converged infrastructure solutions are hastening the path to big-data business value and cloud deployment options.
IoT is the next development of how the Internet is applied to the world. TAM for M2M/IoT is estimated at $19 trillion. The IoT device count is in the billions but will not traverse the service providers’ networks. Service providers and vendors are struggling to understand how to map the TAM dollars to real use cases, optimal technology approaches, and profitable business models.
In his session at @ThingsExpo, Dennis Ward, IoT analyst, strategist at DWE, will focus on the SP transformations that will occur. In Phase I SP infrastructure virtualization. In Phase II SPs will focus on monetizatio...
Most informed CEOs seem to know intuitively that the most qualified person to lead their forward-looking business technology advancement isn’t likely to have the profile of a typical legacy CIO. In contrast, the role of a Digital Business Transformation innovator has very different requirements to the traditional IT utility infrastructure custodian of the past.
That said, some progressive CIOs are already making the transition to lead the digital competit...
We live in a hyper-connected world, and we're sharing information and collaborating on an entirely new scale. Millions of smartphones are sold every day. In a single minute online we send more than 200 million emails, share 2.4 million pieces of content on Facebook, and perform 4 million searches on Google. There are more than 1.3 billion websites out there.
Angel investors, crowd-funding and crowd-sourcing are sparking a rich start-up culture. It has never been easier to realize a good idea. This level of collaboration and the sophistication of connectivity are casting everyone as an innovat...
I am not sure how many people remember Cisco SANTap. About ten years ago, Cisco introduced a data tapping mechanism in the MDS 9000 fibre channel switches. The idea was to allow the data path to be “tapped” at-will. Tapping in this case meant using a mechanism in the switch to split the data being written from client hosts to the storage, allowing the identical “split” data to be routed through a second, separate path.
SANTap therefore allowed a copy of the data to be seamlessly “mirrored” through the switch and subsequently used by other applications for multiple purposes (especially for ba...
Disaster Recovery isn’t a new concept for IT folks. We’ve been backing up data for years to offsite locations, and used in-house data duplication in order to prevent the risks of losing data stores. But now that cloud adoption has increased, there have been some shifts in how traditional Disaster Recovery is being handled.
First, we’re seeing increased adoption of cloud-based backup and disaster recovery. Gartner stated that between 2012 and 2016, one third of organizations are going to be looking at new solutions to replace current ones particularly because of cost, complexity or capability....
What does “big enough” mean? It’s sometimes useful to argue by reductio ad absurdum. Hello, world doesn’t need to be broken down into smaller services. At the other extreme, building a monolithic enterprise resource planning (ERP) system is just asking for trouble: it’s too big, and it needs to be decomposed.
In 2011, then United States CIO Vivek Kundra released the US Federal Cloud Computing Strategy . In the executive summary he pointed to cloud computing as a key component of the US Federal Government’s information technology modernization efforts:
“Cloud computing has the potential to play a major part in addressing these inefficiencies and improving government service delivery. The cloud computing model can significantly help agencies grappling with the need to provide highly reliable, innovative services quickly despite resource constraints.”
The journey through IT transformation is an unstructured one, obviously.
Fraught with perilous pitfalls and uncertainties for the faint hearted, the progression path toward decoupled, decentralized and essentially virtualized new IT frameworks is no walk in the park – hence the need for a guiding migration structure (and/or migration partner) to get from A to B (or more often, A to Z) in one piece.
But the journey to IT transformation is also one of unstructured data, i.e., the need to be able to build (and successfully operate) database and application structures that have an inherent abil...
We all are striving for success. Whether it’s in our personal or professional lives, that’s what we do every day, day in and out. Finding ways to succeed, learning new things that make us succeed, and engaging in conversations that help us succeed. I have yet to meet someone who said I am doing things so that I can fail. I am sure you agree.
Success has different meaning to different people. For some, being able to generate more wealth is a sign of success, while for others helping to make a difference in someone else’s life is success. For most of us, I believe it’s a blend of so many things...
The pricing of tools or licenses for log aggregation can have a significant effect on organizational culture and the collaboration between Dev and Ops teams.
Modern tools for log aggregation (of which Logentries is one example) can be hugely enabling for DevOps approaches to building and operating business-critical software systems. However, the pricing of an aggregated logging solution can affect the adoption of modern logging techniques, as well as organizational capabilities and cross-team collaboration. We need to choose our log aggregation tools carefully to make sure that we don't intr...
Cloud security is at the top of every CIO’s list. It is also the first subject that comes up when you engage in a discussion about the cloud. For those of us who followed the recent Ashley Madison story (from a tech perspective), you would agree that while the breach happened for so many reasons, security is at the heart of it. Here are some key aspects for creating a solid organization, keeping cloud security in perspective.
Join Us at the Santa Clara Convention Center in Santa Clara, California, November 3-5
Cloud computing software is eating the world, and each day is bringing new developments in this world.
Yesterday's debate about public vs. private has transformed into the reality of hybrid cloud: a recent survey shows that 74% of enterprises have a hybrid cloud strategy.
Meanwhile, 94% of enterprises are using some form of XaaS – software, platform, and Infrastructure as a Service.
Big Data | Analytics and the emerging Internet of Things (IoT) are driving exponentially increased demands on datacenters and developers alike, as we cross the zettabyte horizon this year.
Containers and microservices are now part of every PaaS conversation, and IaaS providers are increasingly competing for platform customers.
WebRTC continues to reform web communications, and DevOps is pushing its way into an enterprise IT world that is increasingly agile, lean, and continuous.
Through all this, Cloud Expo remains the single independent event where delegates and technology vendors can meet to experience and discuss the entire world of the cloud.
Only Cloud Expo brings together all this in a single location:
