SMACK Stack 1.1
Elodina is a big data as a service platform built on top of open source software.
The Elodina platform solves today’s data analytics needs by providing the tools and support necessary to utilize open source technologies.

Whats SMACK Stack?SMACK stack 1.0 has been traditionally Spark, Mesos, Akka, Cassandra and Kafka lots https://dzone.com/articles/smack-stack-guide and lots lots more https://www.google.com/webhp?q=smack%20stack
Now we are going to introduce SMACK Stack 1.1 and talk more about dynamic compute, micro services, orchestration, micro segmentation all part of what you can do now with Streaming, Mesos, Analytics, Cassandra and Kafka
The free lunch is over!

Many industries still don’t get itXML is everywhere but we have alternatives!
We can support XML interface but don’t have to take on the burden of the extra data. You can save A LOT of overheard just by having a pre-processing step taking the XML, turning it into Avro and processing and storing that.
It works https://github.com/elodina/xml-avro
You can even process the response in Avro but return the result in XML, more on that later though!
You need to be running Mesos. Lots of options here!
What is most important is that you abstract your “Provider” from your “Grid”.
What is “The Grid”?
It is your PaaS layer you deploy too that runs your software. (aka your new awesome super computer)
The grid is your mesos cluster. You are likely going to have more than one so plan accordingly. Think of it as immutable infrastructure, the computer does.
Step 1
“Provider” of compute resources
The Grid … 2.0 ...
https://github.com/elodina/sawfly/blob/master/cloud-deploy-grid.md
Program against your datacenter like it’s a single pool of resources Apache Mesos abstracts CPU, memory, storage, and other compute resources away from machines (physical or virtual), enabling fault-tolerant and elastic distributed systems to easily be built and run effectively. Mesosphere’s Data Center Operating System (DCOS) is an operating system that spans all of the machines in a datacenter or cloud and treats them as a single computer, providing a highly elastic and highly scalable way of deploying applications, services, and big data infrastructure on shared resources. DCOS is based on Apache Mesos and includes a distributed systems kernel with enterprise-grade security.
Data Center Optimization!
But there is more!● Provisioning● Micro Segmentation● Orchestration● Configuration Management● Service Discovery● Deployment Isolation and Identification● Telemetry, Tracing, Ops Stuff, Etc● Oh My!
It boils back down into stacks! https://github.com/elodina/stack-deploy and how you are working with your schedulers in your cluster ultimatlly.
Stack Deploy to the rescue!
In the Grid you need Schedulers!● Kafka – Producer/Consumer-based message queue management● Exhibitor – Supervisor for distributed persistence (like ZooKeeper)● Cassandra/DSE – HA, scalable, distributed NoSQL data storage● Storm – Topology-based Real-time distributed data streaming ● Monarch – Distributed Remote Procedure Calls, Kafka REST interface and schema repository ● Zipkin – Configure, launch and manage Zipkin distributed trace on Mesos● HDFS – Configure, launch and manage HDFS on Mesos (coming soon)● Stockpile – Consumer to “stock pile” data into persistent storage (mesos scheduler only for c* now)● MirrorMaker – Consumer to make a mirror copy of data to destination● StatsD – Producer to pump StatsD on Mesos into Kafka for consumption, preserves layers● SysLog – Producer to pump Syslog on Mesos into Kafka for consumption, preserves layers

Apache Kafka• Apache Kafkao http://kafka.apache.org
• Apache Kafka Source Codeo https://github.com/apache/kafka
• Documentationo http://kafka.apache.org/documentation.html
• Wikio https://cwiki.apache.org/confluence/display/KAFKA/Index
It often starts with just one data pipeline
Reuse of data pipelines for new producers
Reuse of existing providers for new consumers
Eventually the solution becomes the problem
Kafka decouples data-pipelines
Topics & Partitions
A high-throughput distributed messaging system rethought as a distributed commit log.
Intra Cluster Replication
Streaming & Analytics● The landscape of streaming is about to get more fragmented and harder to
navigate. This is not all bad news and it is not much different than where we were with NoSQL 6 years ago or so.
● Different systems are getting really (really (really)) good at different things.○ Dag based systems○ Event based systems○ Query & Execution Engines○ Streaming Engines○ Etc!
