[cs615asa] Meetup Summary

[Brendan Reis]

Topic: "Multi-host, multi-network persistent containers"
URL: https://www.meetup.com/DevOpsContained/events/249268845/

The speaker for the event was Dr. Bruce Parker, a senior solutions
architect for Aerospike, the company responsible for the eponymous NoSQL
database.

As previously mentioned, Dr. Parker went through the advantages of
Aerospike in container deployment, namely:
- Smart Partitions[tm] algorithm to automatically adjust partitions and
rebalance clusters
- Deterministic collision free hashing to map records to partitions
- Optimal redundancy to maintain reliability of data with available hardware
- Decentralized node discovery and management
- Generally graceful failure handling

These features and others allow for the easy, persistent scaling of data
with containers, but don't answer the question of whether or not your
project needs docker or not.
For example, if you're already running VMs, do you really need Docker
containers too? Are you making good use of Docker or is Docker just hiding
more fundamental wrongs in your system or processes?

Toward the end, Dr. Parker started going into data storage strategies, DNS
strategies (using one domain name per container or one domain name for the
entire swarm of clusters), demos illustrating discussed concepts put into
action, etc.

While I think both containers and NoSQL have room to develop and mature, I
think that they show a lot of promise. The increasing sophistication of
containers and methods and systems for deploying them has allowed for much
more complex but resilient, scalable, and worthwhile solutions to be built
such as demonstrated here. Though there may be some inefficiency, the
minimization of time spent hassling with system configurations and the
flexibility of containers and the technologies that directly leverage them
promise a bright future.
