How to run a Multi-AZ stateful application on EKS with AWS FSx for NetApp ONTAP
- This blog examines how to create a stateful application on Amazon EKS with volumes backed by NetApp’s Trident Container Storage Interface (CSI)driver
- FSx for NetApp ONTAP is a fully managed service that provides highly reliable, scalable, performant, and feature-rich file storage built on NetApp’s popular ONTAP file system
- FSx for NetApp ONTAP is good for applications that need high IO and throughput and it is accessible across an AZ boundary like EFS.
- How Amazon FSx for NetApp ONTAP works

Twitter Space: Amazon EKS OP1 feedback
- Justin Garrison is running a Twitter Space that the community can give feedback directly to DAs and PMs working on EKS as we plan priorities for the next year.
Istio has applied to become a CNCF project
- The Istio project is pleased to announce its intention to join the Cloud Native Computing Foundation (CNCF)
- It is almost 5 years since Google, IBM and Lyft launched Istio 0.1 in May 2017

v3.5 data inconsistency postmortem
- Summary: Code refactor in v3.5.0 resulted in consistent index not being saved atomically. Independent crashes could lead to committed transactions not reflected on all the members.
- Impact: No user reported problems in production as triggering the issue required frequent crashes, however the issue was critical enough to motivate a public statement. Main impact comes from losing user trust into etcd reliability.
WEBINAR: Manage with Ease: Application Portability on EKS with Weave GitOps
In this webinar, you will learn:
- How to reduce complexity so a small team can manage large fleets of clusters running in diverse cloud providers as well as on premises
- How to make it easy for your development teams to deliver their applications securely and consistently, regardless of the target environment
- When fixing the main data inconsistency we have found multiple other edge cases that could lead to data corruption
- There’s a list of action items to be implemented to help mitigate this in the future.
