Zwanger-Pesiri Radiology's journey from MPLS to SD-WAN networking began last spring when Joseph Funaro sat down to review carrier contracts that were up for renewal and realized that he could not only save his company money, but also improve network resiliency and his users' application experience.
With 24 outpatient radiology clinics throughout the greater New York metro area requesting or transmitting a terabyte of imaging records a day and requiring access to more than 1.2 petabytes of stored patient data, Zwanger-Pesiri, the largest outpatient medical imaging center in the country by volume, depends on its WAN to provide timely, effective patient service.
Artificial intelligence (AI) and machine learning are two of the latest networking buzzwords being thrown around the industry. The problem is many enterprise network managers remain confused about the real value of these vastly useful technologies.
Emerging network analytics services, powered by AI and machine learning promise to transform traditional infrastructure management models by simplifying operations, lowering costs, and giving unprecedented insights into the user experience – improving the productivity of both IT professionals and their users.
For network staff, the concept and value of these technologies is extremely powerful if applied to the right problems.
Juniper Networks has announced an expanded portfolio of products for companies to become “multi-cloud ready,” unifying both the public cloud and on-premises computing resources.
The new offerings don’t just connect the data center to the cloud; they also cover campus and branch offices, the latter of which can often be overlooked or forgotten due to being remote.
Companies are moving more workloads to the cloud to keep up for a variety of reasons, but a recent study from consulting giant PwC and commissioned by Juniper found that while a majority of enterprise workloads are going to move to the cloud in the next three years, the workload on premises will not diminish. If anything, it will need to keep up with the cloud.
Wi-Fi is quite fickle. The contention between Wi-Fi devices and the dynamic communication medium of the airwaves makes it a sensitive technology with many settings and situations that can slow it down.
And even if you aren’t using high-bandwidth devices and applications, faster Wi-Fi is always better.
My project engineering staff has been getting more and more information requests for Cisco’s new line of Catalyst 9000 switches, especially the 9300 switch. That has me wondering why.
Cisco touts the Catalyst 9300 Series as the next generation of the industry's most widely deployed stackable switching platform that’s built for security, the Internet of Things (IoT), and cloud computing. It’s part of a line of network switches that form the foundation for Cisco's Software-Defined Access, its leading enterprise architecture.
One reason for the increased interest could be Cisco’s recently announced new intent-based networking system. Cisco believes that by adopting an intent-based approach, networks will be able to deliver a solution that introduces an onslaught of applications and devices that provide greater efficiency and address new security threats.
Fresh off a positive earnings call that saw Cisco report $11.9 billion in revenue for the 2Q 2018 — a 3 percent increase from the same quarter in 2017 and the first time in 6 quarters the company reported year-over-year sales increases — CEO Chuck Robbins has a lot to crow about.
First of all, the company's most strategic new direction: The Network. Intuitive, more commonly known as intent-based networking is rapidly finding acceptance amongst customers, Robbins said.
For the most part the dire warnings about running out of internet addresses have ceased because, slowly but surely, migration from the world of Internet Protocol Version 4 (IPv4) to IPv6 has begun, and software is in place to prevent the address apocalypse that many were predicting.
But before we see where are and where we’re going with IPv6, let’s go back to the early days of internet addressing.
Today is Valentine’s Day, and that means showing appreciation to the people you love. I love my kids; my cats; my new puppy, Bodhi; and most of all my wonderful and amazing wife, Christine. She’s a kind, warm and loving person who has been fighting a rare illness called CVID for the past few years and still keeps a smile on her face and stops to smell the roses — something I’m not very good at.
I would also like to use this Valentine’s Day to show appreciation for cool infrastructure innovation because the new stuff is becoming super important.
Standing up a private cloud using technology from multiple vendors is a time-consuming, complex process that involves months of post-deployment tweaking and tuning.
In 2009, VMware, Cisco and EMC formed a joint venture called VCE that aimed to solve that problem. (Note: Cisco and VMWare are clients of ZK Research.) They created a converged infrastructure (CI) product called “Vblock” that brought together VMware software, Cisco servers and networking with EMC storage in a preconfigured, turnkey, validated solution so customers could essentially turn the product on and start using it.
Vblock had 90 percent of the heavy lifting done, with the other 10 percent being unique the organization. Customers loved it, with many saying Vblock was the only way to get a private cloud up and running inside a week.
The Olympic Winter Games in Pyeongchang are underway and all eyes are on the competitors. They are also on the digital infrastructure and technology allowing billions around the world to view world record-breaking moments in real-time. The 2018 Games represent the world’s first deployment of a broad-scale 5G network, thanks to a partnership between domestic telecom provider KT, Intel and Samsung. The new capabilities have been on the horizon for some time. We saw 5G steal the show a year ago at Mobile World Congress, and Verizon and AT&T have each announced plans to offer 5G networks before the end of 2018. So, what does the emergence of 5G networks mean for enterprises?
Demand for SD-WAN delivered as a managed service is exploding as customers see the benefits that SD-WAN can bring to their distributed organizations.
For example, communications service providers (CSPs) such as Verizon, NTT, and BT all report strong demand for SD-WAN services. Plus, hundreds of other CSPs, cable providers (e.g. Comcast), managed service providers (MSPs), and system integrators have recently deployed new SD-WAN services.
We also see that managed SD-WAN revenues are growing rapidly as they displace traditional managed WAN services (e.g. private lines and MPLS) — an addressable market of over $40 billion in business services.
Machine-to-machine (M2M) communication is a significant and growing subset of the larger Internet of Things (IoT) movement, so you have to ask, “Is my network ready for machine-to-machine (M2M) devices?”
Automation is currently the top priority for almost every technology-driven enterprise this year. Ever wondered why automation is taking center stage in the industry today? Why is it impacting and dominating the tech industry?
New innovations and cutting-edge technologies are creating a massive demand among end users for high quality products and services. These customers are not willing to compromise when it comes to time, quality results. This demand for quick turn arounds and impeccable quality can only be achieved with the help of automation. In fact, enterprise automation is now essential when it comes to meeting increasing consumer demands, while digitally transforming the industry along.
IDC tells us that most companies are using more than one cloud and that cloud usage isn’t just about cost savings. Three out of every four companies are using cloud to chase additional revenue in the form of new customers, risk mitigation, IoT enablement or time to market gains. Most are using multiple external cloud services.
However, especially as microservices become the dominant approach to new application development because of the iteration speed improvements that it provides, it has become important to distinguish the different ways that more than one cloud can be utilized. Specifically, the differences lie in where you sit in an organization and what you are trying to optimize from that seat. Although historically we’ve used the terms interchangeably, hybrid and multi cloud are not the same.
Remember just a few years ago, when everyone was talking about cloud computing? While cloud was consuming all the air in the room, few people were paying attention to another technology trend—one with the potential to transform industrial enterprises. I’m talking about edge computing.
The idea of placing computing resources at the network’s edge—at or near where production processes are occurring—is not a completely new idea. Industrial control has relied on distributed computers to control manufacturing machines and processes for decades. But as manufacturers come under increasing competitive pressure, the need to optimize their efficiency, productivity and quality has become a matter of survival. This imperative requirement is driving companies across the industrial spectrum to look at how pushing intelligence out to the edge can help them gain a competitive advantage.
Cisco Enterprise Agreements (“EAs”) are becoming an increasingly popular vehicle for purchasing and consuming software products and services from Cisco.
Network functions virtualization (NFV) enables IT pros to modernize their networks with modular software running on standard server platforms.
Over time, NFV will deliver high-performance networks with greater scalability, elasticity, and adaptability at reduced costs compared to networks built from traditional networking equipment. NFV covers a wide range of network applications, but is driven primarily by new network requirements, including video, SD-WAN, Internet of Things and 5G.
As an IT professional, you were hired for a certain, specialized job. But why can’t you seem to get it done? Maybe you’ve been busy “fighting fires.” For anyone responsible for network infrastructure, that’s a leading culprit. But there are others.
On the theory that to solve a problem first you need to identify it, we’ve listed a number of obstacles that may be keeping you and your team from the mission-critical parts of your jobs. Taking note of these distractions can be a first step toward fashioning solutions that lead to better outcomes for you and your organization.
When things don’t go according to plan and you have to trade your strategic IT roadmap for tactical reactionary decisions - that’s infrastructure firefighting. The network may not be working as intended; capacity planning may be off mark; production issues could be causing outages, requiring in-depth explanation and research to mitigate repeat outages in the future. Outages may require special actions, as we discuss in this article. You may not have signed on to extinguish unwanted fires, but like it or not, that has become part of your job.
Mean Time to Repair (MTTR) is a common term in IT that represents the average time required to repair a failed component or device. In networking, MTTR is often longer than desired because there are many interdependencies, whereby an issue in one part of the network may cause a problem much farther downstream. Furthermore, a configuration change might appear to create a new issue, when in fact it just exposed something that was there all along but hidden.
It takes quite a bit of forensics to get to the root cause of a network problem. In the meantime (pun intended), there is plenty of blame to go around. The Wi-Fi network seems to be at the top of the list when the accusations fly – more so than any other section of the network. Why is that?
When enterprises started moving workloads and applications to the public cloud, it made sense to adapt existing networking technologies to the new domain. But while compute and storage have successfully become ‘cloud-like,’ networking hasn't.
Cloud networking solutions being offered by companies including Aviatrix, Cisco, and Juniper Network are all vying to help organizations solve networking challenges when transforming their infrastructure to public cloud. But as cloud implementations become more complex, it’s becoming clear that cloud connectivity solutions based on virtualized datacenter networking technologies lack the agility and elasticity required to build and scale in the public cloud.
