Microeconomics For Application Performance By @Ruxit | @DevOpsSummit [#DevOps]

JDJ - Mon, 2015-02-23 14:45
About 15 years ago I gave an application performance presentation to some storage guys. Since I was a database jock at the time and didn’t “speak” I/O very well, I had to try a different approach. Rather than speaking over their heads in my own language, or faking it using their language, I tried to pick something neither of us were experts in – microeconomics. What’s interesting is that that presentation became my modus operandi for tuning systems. As I went from customer to customer, each with a different application or architecture, I needed a normalized approach so I didn’t get lost in the technology.

Netflix released RAD, its outlier detection tooling. Flowing Data shares a great graphic aboud the impact of vaccines throughout history.

For Smoother Automation Identify Application Stuff vs System Stuff

Java Lobby Announcements - Mon, 2015-02-23 09:00
I was recently reminded of a key insight included in a presentation from the Datical team at IBM Innovate 2014. They automate migration of databases changes (and naturally have an integration with UrbanCode Deploy). However, because they are application focused, they try to outline what parts of database schema and configuration they manage (the “Application DBA”) and what they don’t...

Using Go To Build a REST Service on Top of MongoDB

Java Lobby Announcements - Mon, 2015-02-23 09:00
I've been following go (go-lang) for a while now and finally had some time to experiment with it a bit more. In this post we'll create a simple HTTP server that uses mongoDB as a backend and provides a very basic REST API. In the rest of this article I assume you've got a go environment setup and working. If not, look at the go-lang website for instructions (https://golang.org/doc/install). ...

Ways of Expressing Estimates

Java Lobby Announcements - Mon, 2015-02-23 08:30
The way we express our estimates color both the way we think about the thing being estimated and the way our estimates are heard. Single value Quite often, when asked for an estimate, people will give a single value. “How long will this take?” “Three weeks.” If the level of trust is sufficient, and the points of reference are sufficiently aligned, then a single value may be fine....

The Pool: An Agile Fable

Java Lobby Announcements - Mon, 2015-02-23 08:30
Once upon a time there was a pool. It was in a club, and the club people loved the pool. This pool had 6 lanes. Each lane was wide enough for 2 persons to swim in parallel. Because the pool was popular, sometimes in certain hours, there were more than 12 people, and then people joined in already populated lanes. It wasn’t comfortable as swimming alone, or with a pair, but it was possible, to...

When Did Agile Become a Social Movement?

Java Lobby Announcements - Mon, 2015-02-23 08:30
Occasionally on my personal Facebook page, I like to post controversial topics and see if we can get a civil conversation going around difficult issues. Civility can sometimes be difficult, but it is really interesting to hear different points of view and learn more about why people believe what they believe. In that spirit, I want to ask you guys a question… Has agile become a social...

Multi-threaded replication with MySQL 5.6: Use GTIDs!

Java Lobby Announcements - Mon, 2015-02-23 08:30
Originally Written by Stephane Combaudon MySQL 5.6 allows you to execute replicated events in parallel as long as data is split across several databases. This feature is named “Multi-Threaded Slave” (MTS) and it is easy to enable by setting slave_parallel_workers to a > 1 value. However if you decide to use MTS without GTIDs, you may run into annoying issues. Let’s look at two of them. ...

Cloud-Based Billing vs Cloud-Driven Billing By @IanKhanLive | @CloudExpo [#Cloud]

JDJ - Sun, 2015-02-22 22:00
The SaaS model has truly revolutionized the way software is being used. Convenient, hosted on the now cloud, without the need for IT or hardware and so many more advantages. So what is cloud-based billing? A recent piece by Gigaom helps explain why cloud billing is beneficial and how it helps vendors move all aspects of a paper-based system to the cloud. But isn’t that old technology? Isn’t that about generating a PDF file and sending it to your customers instead of a printed invoice? Perhaps not. Perhaps this is about a billing system that works for the SaaS software, charges customers online and they can pay online. Perfect! This is turning out to be good.

Account Sharing in SPM, Logsene and Site Search Analytics By @Sematext | @DevOpsSummit [#DevOps]

JDJ - Sun, 2015-02-22 17:00
Using Cloud (aka SaaS) applications is natural for most of us — simply sign up with your email, login and then use the service within minutes. The Cloud works particularly well with consumer-oriented services. Businesses, however, have slightly different needs. Up until now, Sematext Apps offered only App sharing. For instance, if you had an SPM App for monitoring your Elasticsearch cluster, another SPM App for monitoring Spark, and a Logsene App where you shipped all your logs, you could invite one or more of your teammates to each one of those apps separately, and give them either Admin or User role. This works fine when you have just a few teammates or just a few Apps.

Four Steps for Securing Your Data in the Cloud | @CloudExpo [#Cloud]

JDJ - Sun, 2015-02-22 17:00
Cloud has become part of the enterprise landscape with nearly 90 percent of businesses having adopted cloud-based apps and services. However, organizations need to make sure that these cloud solutions don’t compromise the hard-won security policies that govern the rest of the information enterprise and are supported through IT. As organizations shift to embrace popular cloud-based applications like Office 365, Salesforce, and other services that support the business, identity access management (IAM) solutions become crucial for maintaining productivity and security. Additionally, a single sign-on (SSO) solution that is deployed in conjunction with a solid IAM strategy streamlines access to thousands of cloud applications and enforces necessary security policies. It allows users to easily access the applications and services they need with a single click.
