The World of Hadoop and Beyond By @JnanDash | @CloudExpo [#BigData]

JDJ - Fri, 2015-01-30 21:45
Hortonworks went through an IPO last Friday, December 12, 2014. It’s initial price of $16 soared by 60% immediately after. Today the stock price is $24.70 with a market cap of $1.02B. Another billion dollar club member. They compete with Cloudera and MapR in packaging the open source Hadoop platform for customers. How do they make money when the basic Apache Hadoop is free? – by offering added services like training and consulting. They can also add auxiliary products (not open source) that customers must pay for. The interesting fact is that Hortonworks’s CEO had claimed a $100m revenue this year, but looks like he is way short of that – $33m during first nine months. The future is quite uncertain!

Use Case: Spark Performance Monitoring By @MLnick | @CloudExpo [#BigData]

JDJ - Fri, 2015-01-30 21:00
At Graphflow, our mission is to empower online stores of all sizes to grow their businesses by providing them access to the same machine learning and Big Data tools used by the largest and most sophisticated tech players in the market. To deliver on this mission, we decided from the very beginning to go ‘all in’ on Spark for our scalable analytics and machine learning applications. When Graphflow started using Spark, it was on version 0.7.0, and it was relatively immature. A lot has changed over the past year and a half: Spark has become a top-level Apache project, version 1.2.0 was released, and Spark has matured significantly in terms of functionality, deployment, stability, and operations.

Cloud Document Storage Solutions By @IanKhanLive | @CloudExpo [#Cloud]

JDJ - Fri, 2015-01-30 21:00
Cloud-based document storage has become surprisingly inexpensive over the years, with some providers offering storage for less than one cent per terrabyte, and in many cases free accounts with 10 or 20 Gigs of storage space on the cloud. I would agree that free storage is actually convenient when it comes to being able to upload documents, data, files photos and a bunch of other stuff to the cloud and downloading it where you want, when you want. Things are looking pretty positive for the consumer. Life is good!

Key Performance Metrics: Part 2 By @GrabnerAndi | @DevOpsSummit [#DevOps]

JDJ - Fri, 2015-01-30 19:45
In Part I of this blog I explained which metrics on the Web Server, App Server and Host allow me to figure out how healthy the system and application environment is: Busy vs. Idle Threads, Throughput, CPU, Memory, etc. In Part 2, I focus on the set of metrics captured from within the application server (#Exceptions, Errors, etc.) as well as the interaction with the database (connection pools, roundtrips to database, amount of data loaded, etc.). Most of the screenshots shown in this blog comes from real performance data shared from our Dynatrace Free Trial users that leveraged my Share Your PurePath program where I helped them analyze the data they captured. I also hope you comment on this blog and share your metrics with the larger performance testing community.

‘Real-Time Big Data’ By @CodeFutures | @CloudExpo [#BigData]

JDJ - Fri, 2015-01-30 16:30
You use an agile process; your goal is to make your organization more agile. But what about your data infrastructure? The truth is, today's databases are anything but agile - they are effectively static repositories that are cumbersome to work with, difficult to change, and cannot keep pace with application demands. Performance suffers as a result, and it takes far longer than it should to deliver new features and capabilities needed to make your organization competitive. As your application and business needs change, data repositories and structures get outmoded rapidly, resulting in increased work for application developers and slow performance for end users. Further, as data sizes grow into the "Big Data" realm, this problem is exacerbated and becomes even more difficult to address. A seemingly simple schema change can take hours (or more) to perform, and as requirements evolve, the disconnect between existing data structures and actual needs diverge.

Identity Mixer Launched by @IBM Software | @CloudExpo [#Cloud]

JDJ - Fri, 2015-01-30 16:00
IBM has announced software that allows people to hide or anonymize their personal information on the Web, ensuring protection from identity theft and other misuse. Developed by researchers at IBM's laboratory in Zurich, Switzerland, the software – called Identity Mixer – will enable consumers to purchase goods and services on the Internet without disclosing personal information. As consumers hand over personal details in exchange for downloading music or subscribing to online newsletters, they leave a data trail behind that reveals pieces of information about the size, frequency and source of their online purchases that can be traced back to the user. IBM's Identity Mixer software eliminates the trail by using artificial identity information, known as pseudonyms, to make online transactions anonymous. For example, the software allows people to purchase books or clothing without revealing their credit card number. It can confirm someone's spending limit without sharing their bank balance, or provide proof of age without disclosing their date of birth.
