In Part V, we discussed processing delays caused by “slow” client and server nodes. In Part VI, we’ll discuss the Nagle algorithm, a behavior that can have a devastating impact on performance and, in many ways, appear to be a processing delay. Beyond being important for (reasonably) a...
Followers of the Enterprise File Share and Sync Market (EFSS) will have noticed a flurry of announcements in the last few weeks. In particular: SAP and OpenText collaborated with Tempo Box; Egnyte outlined it would leverage Google's Storage; Box purchased Stream as well as announcing ...
An expected deluge of data and information about patients, providers, outcomes, and needed efficiencies is pushing the healthcare industry to re-evaluate interoperability, security and the ability to adapt rapidly to the lessons in the data. The means of enabling Boundaryless Informat...
A newly established firm sent out some basic information collateral to introduce itself this summer – and a new type of business model would seem to be emerging. The company here in question described itself as a non-integrated silo-based business that was disparately fragmented into ...
Ensuring a safe work environment can be accomplished when individuals work in either a government or private-sector office, but it becomes exponentially more complicated when employees are mobile, traveling from one job or worksite to another. While many organizations implement mobile ...
In Part IV, we wrapped up our discussions on bandwidth, congestion and packet loss. In Part V, we examine the four types of processing delays visible on the network, using the request/reply paradigm we outlined in Part I. From the network’s perspective, we allocate the time period bet...
We know that losing packets is not a good thing; retransmissions cause delays. We also know that TCP ensures reliable data delivery, masking the impact of packet loss. So why are some applications seemingly unaffected by the same packet loss rate that seems to cripple others? From a pe...
We talk a lot about so-called ‘business transformation’, but what do we really mean by this expression and how does it change the way (as workers) now operate on the shop floor? Read any history of the industrial revolution and you will understand the massively impactful swings that o...
In Part II, we discussed performance constraints caused by both bandwidth and congestion. Purposely omitted was a discussion about packet loss – which is often an inevitable result of heavy network congestion. I’ll use this blog entry on TCP slow-start to introduce the Congestion Windo...
When we think of application performance problems that are network-related, we often immediately think of bandwidth and congestion as likely culprits; faster speeds and less traffic will solve everything, right? This is reminiscent of recent ISP wars; which is better, DSL or cable mode...
Monitoring application performance on the surface and the currents below is a great way to build a performance baseline and provide application fluency. Ironically, the deep dive tools sets in place today still may not provide all the insight you need to quickly resolve anomalous behav...
As a network professional, one of your newer roles is likely troubleshooting poor application performance. For most of us, our jobs have advanced beyond network “health,” towards sharing – if not owning – responsibility for application delivery. There are many reasons for this more jus...
Cloud has been on a lot of boardroom agendas for quite a while, but typically those discussions have focused on using cloud around edge applications – expenses management, human capital management or perhaps customer relationship management. However, as the cloud cover extends to busin...
Few companies are able to implement Agile Development across the organization because there exists a chasm between the Application Development team and the Database Administrators. All too often, database development is an afterthought in Agile Development. Developers perfect how be...
First and foremost you can’t have a successful software-defined model if your team still have a hardware-defined mentality. Change is inevitable and whether it's embraced or not it will happen. For experienced CIOs this is not the first time they've experienced this technological and c...
Let me ask you a question: would you say that you have implemented logging correctly for your application? Correct in the sense that it will provide you with all the insights you require to keep your business going once your users are struck by errors? And in a way that does not advers...
You can spend MILLIONS every year improving and maintaining your application, but if you have no insight into your competition how do you know your place in the market and if all that investment has been worthwhile? “If you know the enemy and know yourself, you need not fear the resul...
In order to create the combination between top-down (waterfall like approaches)and local problem-decisions (Agile project approach) here are practical guidelines to pursue Three practical complex decision-problems guidelines: Simple local rules Strategic top down rules Visual probl...
Enterprise Resource Planning has traditionally been a software for large corporates with million dollar technology budgets. But that has been changing over the past decade with the advent of cloud based ERP systems. According to a survey conducted by Sage, nearly 30% of finance manager...
The next BriefingsDirect case study interview explores how improved visibility analytics and predictive responses are improving supply-chain management. We’ll now learn how SAP’s Supplier InfoNet, coupled with the Ariba Network, allows for new levels of transparency in predictive analy...
Let us pose the question: Is business transformation a dirty word? Okay it’s words plural, but you get the point. To start with we must realize why we are asking the question. It’s probably because the phraseis so prevalent at the moment. Every IT management guru worth his or her sa...
The Bloomberg Agile Architecture™ (BAA) Technique offers a way of thinking about and doing architecture that is laser-focused on business agility as the fundamental business driver. Yet while the BAA Technique is an approach to Enterprise Architecture, it’s not a framework or a methodo...
Knowledge creation is a major source of value creation. And great companies –and their employees – know that continuous learning is a key to generating knowledge, and thus value. The agile mindset, particularly in development, is gaining popularity, with credit to a suite of powerful i...
The first time I keynoted about the Agile PMO I received the following question: ‘do you mean that the PMO is in itself managed in an Agile way, or do you mean that the PMO governs projects which are managed in an Agile approach?' Good question! As a smart consultant my immediate a...
Last week's Joyent outage brought us thinking how many IT teams make the effort what is the meaningful downtime that will not have significant impact on their business. In this post I will not discuss this particular outage although it is a yet another good example for improving the IT...
The Agile Architecture bar is set. Vendors should know what their products must do. Architects have some insight into the patterns they must follow. And business stakeholders can finally rest assured that at least it’s possible to achieve technology-enabled business agility. True, it’s...
New Ariba spot-buying service allows companies to bring "emergency" or small purchases under control. It remains one of the last bastions of enterprise spend over which companies have little or no control. Yet companies have been loathe to tamper with how their employers and managers ...
As we know, the subject of Big Data and the ‘space race’ to produce software application development functions that will enable us to extract insight and (therefore) value from the Big Data mountain remains one of the most discussed issues in information technology today. Increasingly...
In production support it is often hard to correlate what might be happening on local servers with what users are reportedly experiencing. In April, the developers for a Java application that handles electronic distribution of scanned mail and electronic faxes were receiving reports tha...
Have you ever deployed a change to production and thought “All went well – Systems are operating as expected!” but then you had to deal with users complaining that they keep running into errors? We recently moved some of our systems between two of our data centers – even moving some c...
Good optimization best practice can help a CIO to lower operating costs, increase asset utilization and employee productivity Somewhere back in the mid-nineties we started talking about optimization (or optimisation if you prefer) as if it were some part of the de facto terminology th...
Dynamic coupling, therefore, represents a paradigm shift in how to build and utilize APIs. Up to this point in time, the focus of both SOA and REST has been on building loosely-coupled interfaces: static, contracted interfaces specified by WSDL and various policy metadata when those in...
Today, more than ever, end user experience is at the forefront of every CTO and CMO’s mind as more statistics show websites and applications are easily abandoned if users are not satisfied with their experience. But what makes a good experience? First we need to ask ourselves what is ...
I wish this book would have been around a few years ago. At the time I was trying to convince a manager for several months that the top-down command and control model no longer works. The evidence was not difficult to come up with, you just had to take a look at the last 4 to 6 project...
A recent global survey commissioned by CA Technologies and conducted by Vanson Bourne illustrates how radically the role of IT is changing in today’s business -- and not always to the benefit of IT leaders and staffers. The survey of 1,300 senior IT leaders from large organizations in ...
The Internet has been buzzing over the recent news of a federal proposal that creates the equivalent of “slow” and “fast” lanes online. The Federal Communications Commission (FCC) voted on Thursday, May 15, 3-2 in favor of a new proposal that enables the creation of Internet fast lanes...
In many companies, the business leadership team, the application team and the infrastructure team are all different entities. And while they are all very dependent on each other in many ways, often organizational goals and alignment can be very different for each team. For example, bu...
Having the latest technologies can be great. But gambling with a possibly steep learning curve and the risk of unexpected faults in new technology can cost your organization more than just the expense of the upgrade. Why run these risks when your current tech already does what you need...
The industry’s jargon can be hard to decipher at times, especially when trying to explain these buzzwords to fellow co-workers within your organization who don’t really have a clue what you are talking about. Buzzwords are unavoidable, however there needs to be a clear understanding of...
With the establishment of mobile web and native mobile apps, your website isn’t the only customer touch point anymore. Mike Austin, Director of e-Commerce at RoomsToGo said it best: “Our customers expect the same experience throughout all our channels no matter if it is the website, m...
