We have already received multiple super proposals from various countries. There are excellent talks with the topics Modern data center, Data Science toolkit, Distributed monitoring, Hitchhiker’s Guide and more. We are super excited to present:
Ander Juaristi Alamos | Senior Security Researcher | Hitchhiker’s guide to TLS 1.3 and GnuTLSAnder
Akmal Chaudhri | GridGain System | Apache Ignite: the in-memory hammer in your data science toolkit
Mike Place | SaltStack | Introduction to SaltStack in the modern data center
Mitchell Hashimoto | HashiCorp | Update on Terraform
Gianluca Arbezzano | InfluxData | Distributed monitoring
We are looking forward to welcoming the speakers in Berlin. We are also awaiting your proposals on https://osdc.de/submit-a-talk/ . Only two weeks left to submit your proposal to be a speaker at the International Open Source Data Center Conference 2018 in Berlin.
Don’t miss it!
March 2010: When our customer needed to centrally monitor the latency of IT services across their 3 offices in Germany, America and Sweden, they were looking for a speedier alternative to their existing solution. Remote monitoring was not meeting their standards, as relying on an international link was all but efficient.
So Bernd came in with an ESB idea. Implementing Mule in their 3 locations, the set up included a server based in Germany and satellites in America and Sweden. The satellites read status and performance data from their file systems to send to the server, which in turn stored the data in an external command file. In processing commands, the server then read from NDO/IDO-DB, reviewed the content and sent the commands to the corresponding satellites. These satellites then also stored the data in an external command file.
Supported by Mule ESB, the satellites could be connected far more tightly and information could flow smoother. Moreover, transforming their makeshift bundle of scripts into a centralised system also meant the entire process itself could be more easily monitored with the handy check_jmx4perl. All in all, a more dynamic and flexible solution thanks to Mule.
November 2009: Offering media services in over 30 languages, the internationally acclaimed Deutsche Welle was seeking to monitor their equally diverse IT. Large and distributed across two offices in Bonn and Berlin, the broadcaster needed to consolidate their disparate monitoring activities into one enterprise system. A central overview was essential, as was exceptionally high availability. Deutsche Welle offered NETWAYS the opportunity to suggest a solution- and an innovative one was proudly delivered.
Since monitoring needed to be self sufficient at each location while being centrally accessible, the consulting team designed a multiple redundant system. Two monitoring clusters were implemented in each city and integrated by a single MySQL cluster. In a master/master failover, each database was also physically located in their respective city. This amounted to two physical Nagios servers and one database at each office, which could operate independently if ever a break in connection were to occur. Furthermore, two physical Nagios servers at each location gave additional guarantee of constant availability. By using the MySQL cluster as a kind of interchange hub, monitoring was centralised without compromising operational independence.
Upon implementation, an array of Nagios addons and plugins were also employed. From NSClient++, SNMPTT and NagVis to EventDB, NagiosGrapher and Business Process Addon, Deutsche Welle was fully equipped by the end of the project. All that is left is a few days training to equip the staff with the skills for a similar operational independence.
