My notes from the Scale Summit unconference (2015). Given as a learning lunch session.

Transcript

2. • Monitoring / Alerting / Metrics • The State of “The Cloud” • Developer Tooling • Service Discovery • Containers are now a thing • Other Trends
3. Monitoring • Nagios • Sensu • Riemann Nothing new really, Nagios isn’t dead yet, but Sensu is gaining traction and has MUCH nicer UI’s
4. Alerting • A few folks toying with anomaly detection ◦ Skyline / Occulus ◦ Homegrown stuff • Graphite Beacon ◦ https://github.com/klen/graphite-beacon
5. Metrics • Graphite is still king • Some folks are playing with… ◦ InfluxDB ◦ Prometheus • Some folks talking about “Event Logging”
6. The State of “The Cloud” • >90% of the crowd use AWS ◦ a couple using Digital Ocean ◦ a couple running their own metal ◦ 1 person using Google Cloud • Cloud config tools ◦ Unless you’re on AWS, they’re of limited use... ▪ Terraform - new, looking very good
7. The State of “The Cloud” • Platform As A Service ◦ Cloud Foundry ◦ Mesos ◦ Kubernetes ◦ Open Shift ◦ CoreOS / Fleet ◦ Docker Machine / Swarm
8. Developer Tooling • Jenkins Job Builder ◦ Automate Jenkins project setup • Automatically check docker images on build/deploy ◦ For insecure software versions ▪ OpenSSL ▪ Bash
9. Service Discovery • Etcd • Consul • Smart Stack Consul was talked about very favourably.
10. Other Trends / Things
11. Containers Are A Thing “Gateway drug to immutable infrastructure” • Containers as a concept are here to stay • Docker isn’t perfect… ◦ Security issues ◦ Stability issues • Alternatives are being developed ◦ Rocket, Garden etc.
12. Old and New Things • Microservices ◦ No longer a talking point - it’s the done thing ◦ Adoption of containers is driving this • HTTPS everywhere • Time Series Databases are a hot topic ◦ InfluxDB, OpenTSSDB, Cassandra, Informix? • Node.js/GO becoming commonplace • Perl 6 is coming!
13. Falling Out of Favour • Ruby is no longer cool - it’s a workhorse • Scala had some backlash ◦ claims of fundamental flaws, small vocal pockets maybe? ◦ Possibly Java 8 stemmed the tide somewhat...
14. Still Not Things • Haskell ◦ Lost the buzz, but without losing people using it. ◦ Looted for ideas by other languages. ◦ Functional buzz is dying out some. • Hack/HipHop • Linux on the desktop
15. What Will Happen? • Google Cloud may become usable • Something will go wrong in service discovery • Malicious docker image everyone downloads • MongoDB will die?
