Robust Applications in Mesos Using External Storage

on YouTube ↗52m

" summary

Compares direct‑attached versus external volumes on Mesos and DC/OS, shows concrete tools and outcomes: uses REX‑Ray and Mesos’ volume isolator to attach external volumes, demonstrates a ScaleIO-based on‑prem option and a ScaleIO framework that runs on Mesos, and cites a real Cassandra rebuild that can take up to 15 days without external storage while external volumes reduce rebuild work to minutes by moving the volume with the container. Mentions emerging CSI standard.

2. 4:35Container Advantages Make Sense for States Too Container attributes Orchestration can adt . Consistent environment - Health mentoring same anywhere • Automated rolous and Dependency management-packaging. Declarative configuration
3. 16:43Initial Deploy Using Local Disk . Simple and straightforward • Performance based on compute node storage capabilities • Targeted deploy based on resources
4. 22:02Day 2 Operations Using Local Disk Data locality!
5. 25:35Day 2 Operations Using External Storage External volume moves with the Container - Hardware failure
6. 28:41What about NoSQL & KeyValue Stores? Initial Deploy - Local disk: Same External storage Same - Day 2 Operations?
7. 31:17Making operational aspects easier Scale out & Scale in - Monitoring - Automated recovery - Bootstrap and rebuild • Elephant in the room!
8. 37:40repair process is expensive - Your application... Slows down Grinds to a halt Can even bring down Cassandra If you aren't careful
9. 40:36Cassandra node failure Bad Disk Compute failure Network partition Maintenance
10. 41:43Minimize window of vulnerability • Run node repair tool Not a full node rebuild Delta - Migration time
