Two of the hottest trends in networking today are network dis-aggregation and SDN. This is great for many reasons. It's also confusing. The marketing hype makes it hard to understand either topic. SDN has become so vague that if you ask 10 experts what it means, you are likely to get 12 different answers. Network dis-aggregation seems straightforward enough until it gets confused with SDN. We need to take a step back. In a recent Packet Pushers blog post; I start with a simple explanation of each of these trends and then map how they interact. more
For small businesses, effectively managing technology comes with a question: Is it better to outsource or stay in-house? Most small and midsize companies can't afford to employ teams of full-time IT staffers. This creates a desire for outsourced solutions. However, opting for a third party means giving up a measure of control. What is best for your business? In this post, we offer a quick rundown of the top five tasks any small business should consider outsourcing. more
Between September of 2015 and May 2016, (last 8 months) Port25 saw almost a 30 percent jump in new cloud-based email infrastructure interest outside the United States... While most of the influential senders are not abandoning on-premises mail transfer agent (MTA) solutions, many are looking to cloud infrastructure for managing higher-volumes by bifurcating individual email streams to the cloud. more
It is good to see Europe take an important leadership role in recognizing the critical contribution that commercial cloud providers can play in providing solutions for big science through their recent Helix Nebula -- the Science Cloud announcement. It is estimated that 1/3 of the science applications running on expensive HPC facilities could easily run on commercial clouds, freeing up these facilities to focus on true high computational problems. more
How do you achieve excellence in the cloud? Enterprises know it's not enough to simply locate and leverage the services of a cloud provider: using cloud resources effectively marks the difference between "adequate" and "excellence" in achieving long-term IT and revenue goals. But to maximize cloud use, you need to know what's next for this disruptive market: here are four emerging techniques. more
Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) have been picking up the pace as of late. A high percentage of communication service providers and large data centers have either added these technologies on their roadmaps, or are already doing small-scale Proof-of-Concepts (PoC) in their testbed environments. more
If you are a cloud provider, whether you are pure play or an internal IT department, it is very interesting to know who is buying cloud services, and why. In a recent survey by PB7 sponsored by EuroCloud Netherlands and others, a group of Dutch companies was interviewed about their motivations and hesitations around cloud computing. The survey's results were quite a bit more interesting than the usual lot. In this article I have cherry picked a few observations from the larger survey. more
The cloud computing scandal of the week is looking like being the catastrophic loss of millions of Sidekick users' data. This is an unfortunate and completely avoidable event that Microsoft's Danger subsidiary and T-Mobile (along with the rest of the cloud computing community) will surely very soon come to regret. There's plenty of theories as to what went wrong -- the most credible being that a SAN upgrade was botched, possibly by a large outsourcing contractor, and that no backups were taken... more
The world of networking tends to be bistable: we either centralize everything, or we decentralize everything. We started with mainframes, passed through Lotus 123 hidden in corners, then to mini's and middleware, then to laptops, and now to the cloud, to be followed by fog. This particular cycle of centralization/decentralization, however, has produced a series of overlapping changes that are difficult to decipher. You can somehow hear someone arguing about disaggregation and hyperconvergence through the fog -- but just barely. more
Companies are moving to the cloud. According to Cloud Tech, CIOs are on the front lines: In 72 percent of companies surveyed, chief information officers lead the cloud computing charge. However, adoption without the right information is doomed to fail - here are 10 key questions CIOs should ask before moving operations to the cloud... First, it's critical to identify business benefits. Here the key to success lies in specifics rather than generalities... more
Vendor revenue from sales of infrastructure products (server, storage, and Ethernet switch) for cloud IT, including public and private cloud, grew by 9.2% year over year to $32.6 billion in 2016, with vendor revenue for the fourth quarter (4Q16) growing at 7.3% to $9.2 billion. more
Way back in the olden days, folks decided that cities should invest lots of money in public transportation systems. The reasons were many fold, including reducing the number of individual vehicles being driven in too, and parked in, congested "downtown" areas, and increasing traffic to businesses in those areas, increasing their commercial viability. Many of these systems are sold to the public with the idea that they will (at least) break even against capital and operational expenses over time, but the reality is far different. more
Who do you think deserves recognition in the Internet Hall of Fame? Do you know of someone who has played a key role in the Internet's development who should be recognized? (And is not already among the existing IHOF inductees?) If you know of someone who deserves the recognition, nominations are open until March 15, 2017. As outlined by Internet Society President & CEO Kathy Brown in a blog post today, the Internet Hall of Fame seeks to honor three types of inductee. more
If you are passionate about ICT policy, Peering, and Interconnection, then the Africa Peering and Interconnection Forum (AfPIF) is the place to be. The 7th annual AfPIF takes place in Dar es Salaam, Tanzania from 30 August – 1 September 2016. AfPIF is a multistakeholder forum organized by the Internet Society that brings together a diverse range of business leaders, infrastructure providers, Internet service providers (ISPs), Internet Exchange Points (IXPs), international financial institutions, policy-makers, and regulators from all over the world. more
Cloud Computing is a hot topic. Some say it is already here, most agree that it will be much bigger in the coming years. It is pushed forward by the economic benefits of virtualization and consolidation. Take a heterogeneous data center, full of many kinds of servers, running a myriad of applications and consolidate it into a uniform farm of virtual machines, where each application is services by one or more VMs and you have a cloud, what is called a private cloud. more
