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:
Predictive analytics tools monitor, report, and troubleshoot in order to make proactive decisions about the health, performance, and utilization of storage. Most enterprises combine cloud and on-premise storage, resulting in blended environments of physical, virtual, cloud, and other platforms, which justifies more sophisticated storage analytics. In his session at 18th Cloud Expo, Peter McCallum, Vice President of Datacenter Solutions at FalconStor, discussed using predictive analytics to mon...

We all know the latest numbers: Gartner, Inc. forecasts that 6.4 billion connected things will be in use worldwide in 2016, up 30 percent from last year, and will reach 20.8 billion by 2020. We're rapidly approaching a data production of 40 zettabytes a day – more than we can every physically store, and exabytes and yottabytes are just around the corner. For many that’s a good sign, as data has been proven to equal money – IF it’s ingested, integrated, and analyzed fast enough. Without real-ti...

Qosmos has announced new milestones in the detection of encrypted traffic and in protocol signature coverage. Qosmos latest software can accurately classify traffic encrypted with SSL/TLS (e.g., Google, Facebook, WhatsApp), P2P traffic (e.g., BitTorrent, MuTorrent, Vuze), and Skype, while preserving the privacy of communication content. These new classification techniques mean that traffic optimization, policy enforcement, and user experience are largely unaffected by encryption. In respect wit...

IoT generates lots of temporal data. But how do you unlock its value? You need to discover patterns that are repeatable in vast quantities of data, understand their meaning, and implement scalable monitoring across multiple data streams in order to monetize the discoveries and insights. Motif discovery and deep learning platforms are emerging to visualize sensor data, to search for patterns and to build application that can monitor real time streams efficiently. In his session at @ThingsExpo, ...

Choosing the right cloud for your workloads is a balancing act that can cost your organization time, money and aggravation - unless you get it right the first time. Economics, speed, performance, accessibility, administrative needs and security all play a vital role in dictating your approach to the cloud. Without knowing the right questions to ask, you could wind up paying for capacity you'll never need or underestimating the resources required to run your applications.

Up until last year, enterprises that were looking into cloud services usually undertook a long-term pilot with one of the large cloud providers, running test and dev workloads in the cloud. With cloud’s transition to mainstream adoption in 2015, and with enterprises migrating more and more workloads into the cloud and in between public and private environments, the single-provider approach must be revisited. In his session at 18th Cloud Expo, Yoav Mor, multi-cloud solution evangelist at Cloudy...
