PuneTech Blog Virtualization is essentially some kind of abstraction of computing resources. There are various kinds of abstractions. Files provide an abstraction of disk blocks into linear space. Storage virtualization products, like logical volume manager, virtualize multiple storage devices into single storage and vice versa. Processes are also a form of virtualization. A process provides an illusion to the programmer that she has the entire address space at her disposal and has exclusive control of hardware resources. Multiplexing of these resources between all the processes on the system is done by the OS, transparent to the process. This concept has been universally adopted. All multi-programming operating systems are characterized by executing instructions in at least two privilege levels i.e. unprivileged for user programs, and privileged for the operating s... (more)

I’m Not Scared of DevOps | @KubeSUMMIT #DevOps #Serverless #APM #Docker #DataCenter #Monitoring #Kubernetes

DevOps is speeding towards the IT world like a freight train and the hype around it is deafening. There is no reason to be afraid of this change as it is the natural reaction to the agile movement that revolutionized development just a few years ago. By definition, DevOps is the natural alignment of IT performance to business profitability. The relevance of this has yet to be quantified but it has been suggested that the route to the CEO's chair will come from the IT leaders that successfully make the transition to a DevOps model. If this still seems foreign to you, I recommend reading up on DevOps Blog from IT Revolution, the OpsCode Blog, and check out The Phoenix Project. Despite all the talk around simple monitoring tools, breaking through the walls between Dev and Ops still poses a real challenge. This is because of a misunderstanding around Operations real pu...

Autonomic SOA Web Services - Achieving Fully "Business-Conscious" IT Systems

Service-oriented architectures (SOA) and autonomic computing are among the hottest topics in IT today. SOA simplifies integration and facilitates the componentization of enterprise-wide systems, thereby enabling optimal business agility. Autonomic computing allows these systems to operate without human intervention - through self-configuring, self-healing, and self-managing capabilities. By combining autonomic computing with SOA, enterprises can now achieve a new IT utopia, named "Autonomic SOA." However, this new level of autonomic computing goes beyond just reacting to traditional IT issues, such as increasing the speed to diagnose, repair, and prevent future issues. Autonomic SOA is also able to respond dynamically as changes occur within business conditions and processes, thereby empowering enterprises everywhere to achieve flawless execution on a daily basis. ...

Amazon Adds Data Portability With New Import/Export Service

Amazon Web Services has announced a new AWS Import/Export feature. A potentially huge step forward for data portabilty when using the Amazon Cloud computing infrastructure. In a recent post by AWS Evangelist, Jeff Barr outlined the new functionality stating that "using a workflow similar to the one you'd use to import data, you prepare a MANIFEST file, email it to us, receive a job identifier in return, and then send us one or more specially prepared storage devices. We'll take the devices, verify them against your manifest file, copy the data from one or more S3 buckets to your device(s) and ship them back to you." A "specially prepared" storage device contains a SIGNATURE file. The file uniquely identifies the Import/Export job and also authenticates your request. You can use the new CREATE EXPORT PLAN email command to simplify the process of exporting a data set... (more)

The Cloud – Modernize as You Migrate

Assuming that your organization is well down the road when it comes to adopting the Cloud and in fact, has been utilizing the Cloud for a while, then you are likely a true believer that ultimately all of your applications will be migrated to the Cloud. It is no longer a question of "if" but more a question of "when" and "how."  These days, the majority of test, dev, external websites and mobile apps are already born in the cloud. Applications make businesses run. Businesses have tons of applications ranging from purchased (commercial off the shelf) to homegrown (bespoke) and likely some customized, purchased apps that now look a lot like the homegrown ones. One of the big problems with apps is that once they are built and deployed they rarely get replaced or decommissioned.   Application sprawl and aging application portfolios are among the root causes for much of th...

The Next-Generation of Business Intelligence

Business Intelligence at Cloud Expo Most people think of traditional business intelligence (BI) as a collection of business-critical information from inside the enterprise. However, consumer comments, independent reviews, and market reports online are crucial pieces of information coming from the outside that infinitely affect any organization. Applications, blogs, social networks, and forums where content creation, sharing, and understanding takes place should be part of business intelligence. Locating and analyzing this unstructured data can only be carried out with a different kind of business intelligence solution - one we call semantic intelligence. What Is Semantic Intelligence? Semantic intelligence provides early identification and analysis of consumer sentiment, purchasing trends, market deals, and competitive information - and uncovers this data not only fr... (more)

Tuscany SCA helloworld-jsp is up and running on Google App Engine

I managed to get an variant of Tuscany SCA helloworld-jsp working on Google App Engine. The application is now up and running at [1]. The composite contains implementation.java, implementation.web and a JSP using SCA taglibs. During the bring-up, I made a few minor changes to Tuscany 2.x code base to fix the two classes that break the the App Engine JRE Class White List: * org.apache.tuscany.sca.node.impl.NodeImpl (java.lang.management.ManagementFactory is restricted) * org.apache.tuscany.sca.core.invocation.impl.JDKProxyFactory (subclassing java.lang.reflect.Proxy is not allowed: org.apache.tuscany.sca.core.invocation.CachedProxy) I have checked in the fixes into trunk and the application into my sandbox at [2]. After checkout, you can run "mvn" to copy the Tuscany jars into the war/WEB-INF/lib folder. Then you can load the project into Eclipse if you have the Google A... (more)

Commentary: Sun’s Oracle Merger

Mergers & Acquisitions on Ulitzer With only the ‘you may now kiss the bride’ custom to follow, the Oracle/Sun marriage (or dare I say Sun/Oracle) is now finally complete. After months of legal wrangling which has caused nothing but embarrassment and dwindled Sun’s stature within the market sphere, reports also came out that half of Sun's 27,000 staff will be made redundant. Thus initial indications are clear that Oracle, known for its past agnosticism to open source has an eye for the merger being based on maximizing profit. In the meantime Sun’s competitors are probably smiling wryly as the delay of the merger played into their immediate interests but what threats and challenges does this partnership now pose to the once great open source vendor which did so much for developing the tech and e-commerce industry. One thing which Oracle will most probably do is addres... (more)

HP & IBM Vie over Next Billion-Dollar Acquisition: Radware

IBM and HP are competing for the hand of Israeli-based smart networking developer Radware whose acquisition will go down for close to a billion dollars according to Globes, the Israeli business paper whose inevitably unnamed and chatty sources are usually on the money. Both IBM and HP are partners of the 14-year-old public company. Globes expects Radware to get knocked down for $45 a share working out to a total of $945 million, a 60% premium. Oddly enough IBM CEO Sam Palmisano Tuesday publicly scoffed at the premiums HP has been paying lately for 3PAR and now ArcSight claiming that it’s only because its internal innovation impulses have been starved by its penny-pinching ousted CEO whereas IBM’s own R&D budget is fat and sassy. Globes quotes Oppenheimer as speculating the other day that Radware could get bought for its IP when it raised its price target to 30 bucks. ... (more)

Microservices Articles
Modern software design has fundamentally changed how we manage applications, causing many to turn to containers as the new virtual machine for resource management. As container adoption grows beyond stateless applications to stateful workloads, the need for persistent storage is foundational - something customers routinely cite as a top pain point. In his session at @DevOpsSummit at 21st Cloud Expo, Bill Borsari, Head of Systems Engineering at Datera, explored how organizations can reap the bene...
"NetApp's vision is how we help organizations manage data - delivering the right data in the right place, in the right time, to the people who need it, and doing it agnostic to what the platform is," explained Josh Atwell, Developer Advocate for NetApp, in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.
The Jevons Paradox suggests that when technological advances increase efficiency of a resource, it results in an overall increase in consumption. Writing on the increased use of coal as a result of technological improvements, 19th-century economist William Stanley Jevons found that these improvements led to the development of new ways to utilize coal. In his session at 19th Cloud Expo, Mark Thiele, Chief Strategy Officer for Apcera, compared the Jevons Paradox to modern-day enterprise IT, examin...

Skeuomorphism usually means retaining existing design cues in something new that doesn’t actually need them. However, the concept of skeuomorphism can be thought of as relating more broadly to applying existing patterns to new technologies that, in fact, cry out for new approaches. In his session at DevOps Summit, Gordon Haff, Senior Cloud Strategy Marketing and Evangelism Manager at Red Hat, will discuss why containers should be paired with new architectural practices such as microservices ra...
In his session at 20th Cloud Expo, Scott Davis, CTO of Embotics, discussed how automation can provide the dynamic management required to cost-effectively deliver microservices and container solutions at scale. He also discussed how flexible automation is the key to effectively bridging and seamlessly coordinating both IT and developer needs for component orchestration across disparate clouds – an increasingly important requirement at today’s multi-cloud enterprise.
The Software Defined Data Center (SDDC), which enables organizations to seamlessly run in a hybrid cloud model (public + private cloud), is here to stay. IDC estimates that the software-defined networking market will be valued at $3.7 billion by 2016. Security is a key component and benefit of the SDDC, and offers an opportunity to build security 'from the ground up' and weave it into the environment from day one. In his session at 16th Cloud Expo, Reuven Harrison, CTO and Co-Founder of Tufin, ...
DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm. In their Day 3 Keynote at 20th Cloud Expo, Chris Brown, a Solutions Marketing Manager at Nutanix, and Mark Lav...
Many organizations are now looking to DevOps maturity models to gauge their DevOps adoption and compare their maturity to their peers. However, as enterprise organizations rush to adopt DevOps, moving past experimentation to embrace it at scale, they are in danger of falling into the trap that they have fallen into time and time again. Unfortunately, we've seen this movie before, and we know how it ends: badly.
TCP (Transmission Control Protocol) is a common and reliable transmission protocol on the Internet. TCP was introduced in the 70s by Stanford University for US Defense to establish connectivity between distributed systems to maintain a backup of defense information. At the time, TCP was introduced to communicate amongst a selected set of devices for a smaller dataset over shorter distances. As the Internet evolved, however, the number of applications and users, and the types of data accessed and...
