Writing code intended to fail… improves performance? In this non-intuitive paradigm, chaotic fault injection forces developers to write more robust code. This results in a product that is more resistant to small faults and ultimately better performing.

Owning a Ruby on Rails blog site hosted on Heroku that was performing adequately was no reason to not improve performance! Alex Browne set to see how fast he could get on a tight budget. In all tests and metrics the new static site running on Jekyll on Octopress is much faster and capable than the old version. For only pennies a month, this is a consideration for anyone with a blog that is starting to cost too much.

This technical article explores TCP congestion operation and settings, ultimately creating a case for upgrading the linux kernel. Updates in the 2.6.38.x kernel and more in 3.2.x provide enhanced and additional algorithms to tune congestion-affecting settings. There is no one best fit solution, and an approach of monitoring and adjusting is advised.

Performance on a datacentre’s TCP network can sometimes be significantly worse than expected. TCP Throughput Collapse, also known as TCP Incast, affects many-to-one TCP links resulting in severe underutilisation of capacity. This is seen particularly in clusters where simultaneous requests are made of many nodes. While this article has a focus on erlang, anyone dealing with similar situations will be interested, particularly cluster storage, web search and MapReduce operations.

Conventional wisdom is that scaling out to a cluster is the way to grow into larger data. This paper by Microsoft researchers demonstrate that with realistic, sub-petabyte, operations it is in fact better to scale up to a larger server. Included are recommendations for Hadoop tuning for scaling up as it is designed to work for scale out. Their results imply that future software infrastructures need to be designed both for good scale up and scale out.

By applying performance improvement tools used on external facing websites and products to intranet sites used internally, teams can become more productive and have a better experience at work. When thinking of customer satisfaction, don’t forget about employee satisfaction. The same rules and tools apply. “By creating a culture of data collecting and sharing, you will be able to better examine the data flows inside your organization, and find the cause of many unexpected problems.”Share Now:
The cloud promises new levels of agility and cost-savings for Big Data, data warehousing and analytics. But it’s challenging to understand all the options – from IaaS and PaaS to newer services like HaaS (Hadoop as a Service) and BDaaS (Big Data as a Service). In her session at @BigDataExpo at @ThingsExpo, Hannah Smalltree, a director at Cazena, provided an educational overview of emerging “as-a-service” options for Big Data in the cloud. This is critical background for IT and data professionals...

"Once customers get a year into their IoT deployments, they start to realize that they may have been shortsighted in the ways they built out their deployment and the key thing I see a lot of people looking at is - how can I take equipment data, pull it back in an IoT solution and show it in a dashboard," stated Dave McCarthy, Director of Products at Bsquare Corporation, in this SYS-CON.tv interview at @ThingsExpo, held November 1-3, 2016, at the Santa Clara Convention Center in Santa Clara, CA.

Fact is, enterprises have significant legacy voice infrastructure that’s costly to replace with pure IP solutions. How can we bring this analog infrastructure into our shiny new cloud applications? There are proven methods to bind both legacy voice applications and traditional PSTN audio into cloud-based applications and services at a carrier scale. Some of the most successful implementations leverage WebRTC, WebSockets, SIP and other open source technologies. In his session at @ThingsExpo, Da...

Today we can collect lots and lots of performance data. We build beautiful dashboards and even have fancy query languages to access and transform the data. Still performance data is a secret language only a couple of people understand. The more business becomes digital the more stakeholders are interested in this data including how it relates to business. Some of these people have never used a monitoring tool before. They have a question on their mind like “How is my application doing” but no id...

Information technology is an industry that has always experienced change, and the dramatic change sweeping across the industry today could not be truthfully described as the first time we've seen such widespread change impacting customer investments. However, the rate of the change, and the potential outcomes from today's digital transformation has the distinct potential to separate the industry into two camps: Organizations that see the change coming, embrace it, and successful leverage it; and...

Extracting business value from Internet of Things (IoT) data doesn’t happen overnight. There are several requirements that must be satisfied, including IoT device enablement, data analysis, real-time detection of complex events and automated orchestration of actions. Unfortunately, too many companies fall short in achieving their business goals by implementing incomplete solutions or not focusing on tangible use cases. In his general session at @ThingsExpo, Dave McCarthy, Director of Products...

The Internet of Things (IoT) promises to simplify and streamline our lives by automating routine tasks that distract us from our goals. This promise is based on the ubiquitous deployment of smart, connected devices that link everything from industrial control systems to automobiles to refrigerators. Unfortunately, comparatively few of the devices currently deployed have been developed with an eye toward security, and as the DDoS attacks of late October 2016 have demonstrated, this oversight can ...

More and more brands have jumped on the IoT bandwagon. We have an excess of wearables – activity trackers, smartwatches, smart glasses and sneakers, and more that track seemingly endless datapoints. However, most consumers have no idea what “IoT” means. Creating more wearables that track data shouldn't be the aim of brands; delivering meaningful, tangible relevance to their users should be. We're in a period in which the IoT pendulum is still swinging. Initially, it swung toward "smart for smar...

We are always online. We access our data, our finances, work, and various services on the Internet. But we live in a congested world of information in which the roads were built two decades ago. The quest for better, faster Internet routing has been around for a decade, but nobody solved this problem. We’ve seen band-aid approaches like CDNs that attack a niche's slice of static content part of the Internet, but that’s it. It does not address the dynamic services-based Internet of today. It does...
