The Maintenance Episode

For some strange reason, “maintenance” has been in the news quite a bit lately. Is there ever a time when maintenance is enjoyable, or appreciated?

• AWS increased the price of longer-running EKS clusters by 6x
• Broadcom changes VMware licensing from perpetual to subscription
• Broadcom offers security patches to perpetual license customers
• Increasing the Kubernetes support window to 1 year
• Discovering the XZ backdoor (Oxide and Friends, podcast)

IS MAINTENANCE EVER APPRECIATED OR ENJOYABLE?

• Spent the day surrounded by maintenance activities (oil, AC, power-wash)
• The costs of maintenance are real and opportunity
• Maintenance often goes unappreciated and unseen
• Naming: Release Notes, Technical Debt, Chaos Engineering

TECHNICAL DEBT VS. MAINTENANCE

• Should we encourage a lack of maintenance vs. innovation as a priority?
• Should we encourage active maintenance with lower hard costs?
• Is there a way to put respect on maintenance? (e.g. OSS maintainers)
• Do we undervalue maintenance (e.g. Backup/Recovery, DisasterRecovery, etc.)?
• What maintenance best practices do you use? What are the good and bad of them?

The Complexities of Edge Computing

It’s smaller computers, doing limited tasks. So why is Edge Computing so complicated, and why are there so many definitions?

THE COMPLEXITIES OF EDGE COMPUTING

No single definition of edge, because of so many use-cases

• Branch office
• Near-Edge 
• Far-Edge
• Disconnected

Hardware can dictate quite a bit about edge characteristics

• Custom-OS or COTS OS
• General purpose HW or Specialized HW (GPU, NVMe, DPUs)
• #of computing devices; volume of local storage

Networking can dictate quite a bit about edge characteristics

• Are the devices always connected to the Internet?
• How are disconnected environments handled?
• How much bandwidth is available? Is it symmetric or asymmetric? 
• What are the traffic patterns of the applications? Local vs. Backhaul. 

Security can dictate quite a bit about edge characteristics

• How does Security happen on Day 0?
• What are the security vs. usability tradeoffs? (direct user interaction) 
• How is security maintained? (CVE, Local Security services, etc.)

Maintenance can dictate quite a bit about edge characteristics

• How much does it cost to deploy new edges?
• How often are the edges expected to be upgraded? 
• How will maintenance happen? (Local tech, remote download, etc.)
• How sophisticated is the Day 2 Ops? (Telemetry, Environmentals, Benchmarks, etc.)
