Cloud security is a top concern for chief security officers. In almost any enterprise, cloud migration is a given fact and recent attacks have proven, yet again, that data security is a critical component in any cloud migration strategy. Below are four tips, specific to Infrastructur...
Modern Data Centers are very complex environments. Data center operators must have visibility into a wide range of integrated data bases, applications, and performance indicators to effectively understand and manage their operations and activities. Unfortunately, in many cases, the ab...
I had a very interesting discussion with a retail customer recently. I guess the retail business experiences employee turnover more than other areas, and the IT department is no exception. A key issue to them was expertise. They look for technologies that can be quickly learned by t...
The DevOps section in the library is not the largest around but it is well worth your time to check a couple out. Here are the Top 10 DevOps Books that are worth finding at the book store and sharing with your friends. Feel free to browse, click on the books, you can’t go wrong....
Technology was dominated by several prevalent trends in 2014 – from the Internet of Things (IoT) and big data to the cloud and cyber security, it seems like there was barely a day without one of these trends creeping up in the news. Now we have entered 2015, these trends are still at t...
In an informal survey of words used during seminars and discussions, two main themes are emerging at the Pacific Telecommunications Council’s 2015 annual conference. The first, as expected, is development of more submarine cable capacity both within the Pacific, as well as to end poin...
Ninety-percent of your users want your site to perform well during peak periods, like the last month or so. That's according to a study by Compuware, in which they also found that most dissatisfied users will throw you under a bus if your app or site performs poorly while they're despe...
Through http://blog.ipspace.net I landed on this article on acm.org discussing the complexity of distributed systems. Through some good examples, George Neville-Neil makes it clear that creating and scaling distributed systems is very complex and “any one that tells you it is easy is e...
One way or another, all data center networks exhibit at least 6 different functional areas that their operators need to engineer, implement, and operate with a differing set of needs and requirements. Similarly, in one way or another, most of the available SDN and virtualized network s...
The race to hire is on. By 2029, the U.S. Census Bureau notes that the entire baby boomer generation will be over the age of 65. But even now, boomers are leaving the workforce in considerable numbers, and finding replacements will be stiff competition among organizations looking to at...
Fraud is definitely top of mind for all banks. Steve Rosenbush at the Wall Street Journal recently wrote about Visa’s new Big Data analytic engine which has changed the way the company combats fraud. Visa estimates that its new Big Data fraud platform has identified $2 billion in poten...
Whenever we get to the end of a year we have this tendency to reflect on what has happened in the past year and how we can improve in the coming year. It’s natural to use the change of calendar year as a point in time to think back, even though practically speaking it is usually the mo...
Usually, it is the task of the system administrator in the organization to make its network stable and reliable. His effective operation requires him to know all the information on network: number of hosts, where they are situated, quality of connections between them, their operation, ...
What do you get when you combine Big Data technologies….like Pig and Hive? A flying pig? No, you get a “Logical Data Warehouse”. My general prediction is that Cloudera and Hortonworks are both aggressively moving to fulfilling a vision which looks a lot like Gartner’s “Logical Da...
Have you figured out the new buzzword trend for 2014 that starting ramping up in 2013? Yup, it’s Internet of Things (IoT) and Internet of Devicess (IoD) Assuming that IoT, IoD and other variations catch on which looks like they will, this could bring relief and rest for the over-work...
Lori MacVittie is responsible for education and evangelism of application services available across F5's entire product suite. Her role includes authorship of technical materials and participation in a number of community-based forums and industry standards organizations, among other e...
All prognosticators, even us who simply roll out a single annual list, hope for two things: one, that your predictions get a lot of traction and shares across the industry, and two, that you end up actually being correct. Anil Batra’s list of 2014 predictions has turned a lot of hea...
The impact is that it's really difficult to apply access controls to something in the cloud using traditional models that force users and consumers to come to the enterprise data center where that service is hosted first. That has a very negative impact on performance, at a minimum. Si...
Database change management is a unique challenge when adopting an agile development practice or implementing DevOps patterns. It really straddles two groups: the developers and the DBAs. Developers design and author the application schema changes based on the needs of the business. ...
If RAID were really not relevant anymore (e.g. actually dead), why do some people spend so much time trying to convince others that it is dead or to use a different RAID level or enhanced RAID or beyond raid with related advanced approaches? When you hear RAID, what comes to mind? ...
While many SPM Performance Monitoring users quickly see the benefits of SPM and adopt it in their organizations for monitoring — not just for Elasticsearch, but for their complete application stack — some Elasticsearch users evaluate SPM and compare it to Marvel from Elasticsearch. We...
The premise of cloud is based, like other emergent technologies, at least partially on the notion of abstraction. Cloud providers are able to achieve what appears to be boundless compute, limitless storage and never-ending network capacity by being able to simply "plug and play" the ha...
Programmability is an integral component of just about every emergent technology and trend today. Cloud? It's based on the ability of providers (public or private) to abstract, automate and orchestrate the network using programmability. DevOps? A significant tenet of DevOps relies on a...
Recently Arista released a white paper surrounding the idea that having deeper buffers running within the network can help to alleviate the incast congestion patterns that can present when a large number of many-to-one connections are happening within a network. Also known as the TCP i...
For business leaders today, it’s not enough to drive company growth, seek competitive advantages and provide vision. In this era of advanced cyberattacks, executives also need to keep their companies’ data security strategies top of mind. The Ponemon Institute’s 2014 Cost of Data Breac...
(article written for the Scality blog) It has been six years since I wrote my first object storage blog, even though I didn’t mention object storage in that specific article. I had my head in the clouds as our early cloud startup was being acquired by Sun Microsystem when someone asked...
I once said on stage at Glue that the reason I loved node.js was, quite frankly, that it's a language and with a programming language you can do, well, anything. But like most things just because you can, doesn't always mean you should. When it comes to business, there absolutely must...
If so, you are not alone! We talk to a lot of people who want to reduce the frequent “noise” from monitoring alarms. To solve this common problem, Sematext added anomaly detection for alerts and PagerDuty integration to its SPM Performance Monitoring solution to dramatically reduce t...
Now that cloud services have become part of IT’s “new normal,” commonly referred to as “hybrid,” it seems obvious that the approaches and tools we use to manage IT would also evolve and mature, though the pace of evolution varies amongst companies, of course. According to a Website Mag...
The SMB market opportunity is huge. Currently, SMBs represent 44% of the total IT spend worldwide, a figure that Gartner predicts will cross the trillion dollar mark by 2015. That's some serious cash -- yet a market that  traditional storage and virtualization players have pra...
So congratulations, somehow you've managed to wangle your way onto one of the many DevOps conferences being held around the world. Why not you might say? DevOps is not only hot it's the approach many enterprises are now exploring as the means to help accelerate the delivery of high qua...
Data centers have matured immensely over the past decade with today’s data centers being greener than ever. Pike Research mentions that the green data center market was worth $17.1 billion in 2012. The green data center economy is expected to grow rapidly throughout this decade. Pike R...
What’s Big Data without Big Compute? Basically just a large collection of unstructured information with little purpose and value. It’s not enough for data just to exist, we must derive value from it through computation – something commonly referred to as analytics. With traditional ...
I talk a lot about SDAS (that's Software Defined Application Services) with respect to F5 Synthesis and, well, F5 in general. That's because what F5 Synthesis delivers the ability to easily provision and orchestrate SDAS across a variety of deployment models (on-premise, in the cloud, ...
Software Defined Application Services (SDAS) are going hybrid. . Organizations are turning to cloud not just as an option for applications but also for the network and application services that deliver applications to anyone, anywhere at any time. And not just "in" the clo...
#DevOps #SDN We keep saying that, does it mean what you think it means? Operationalization (which is really hard to say, go ahead - try it a few times) is a concept that crosses the lines between trends and technologies. Both SDN and DevOps share the notion of "operationalization" as...
The phenomena of Big Data continues to grow as companies of all sizes start to realize the potential ROI that comes from the correct use of massive amounts of data. MIT found that firms who can leverage Big Data can achieve 5-6 percent greater productivity and profitability than their ...
Operationalization (which is really hard to say, go ahead - try it a few times) is a concept that crosses the lines between trends and technologies. Both SDN and DevOps share the notion of "operationalization" as a means to achieve the goal of aligning IT with business priorities, like...
Vichara Technologies in Hoboken, New Jersey is expanding its capabilities in big data from origins on Wall Street into other areas, and thereby demonstrating the growing marketplace for advanced big-data analytics services. The next BriefingsDirect deep-dive big data benefits case stu...
Scene scenario: 10 am in a boardroom somewhere, second round of coffees served, Danish and donuts untouched, a quiet hush settles. “Well you know what guys? (and, by the use of the term guys I mean to include both sexes here assembled) – the trouble that we have as a company is that w...
