Cloud Native Digest: Edge Computing Eats the Cloud?
Edge computing isn’t a panacea, but its timing is impeccable. The cloud is too slow to meet the needs of most edge devices making it necessary to move computing closer.
“Latency is the big killer of cloud computing, especially public cloud computing”, “orchestrated edge systems will become a viable public cloud alternative.”
“Given the many scenarios where internet connectivity is unavailable or sporadic, for example cruise lines, offshore oil rigs, and remote hospitals, we’ll likely see more edge-optimized databases with offline first capabilities in the future, and any company that foresees there being a major interruption in their service due to latency issues will benefit from edge computing,” says Wayne Carter, vice president of engineering at cloud database provider Couchbase.

HashiCorp Vault Improves Multi-Namespace Workflows, Adds Managed Service for Azure
HashiCorp has released version 1.13 of Vault, their secrets and identity management platform. This release includes multi-namespace access workflows, improvements to the Google Cloud secrets engine, usability improvements to MFA, and certificate revocation for cross-cluster management. HashiCorp has also released Vault as a managed service for Microsoft Azure environments.
This release introduces namespace improvements that allow for a single Vault Agent to fetch secrets across multiple namespaces. Namespaces provide isolated environments that enable tenant isolation within a single Vault instance. Previously, applications would need to authenticate per namespace with distinct Vault Agents needed per namespace.
Istio ambient service mesh merged to Istio’s main branch
Istio ambient service mesh was launched in Sept 2022 in an experimental branch, introducing a new data plane mode for Istio without sidecars. Through collaboration with the Istio community, across Google, Solo.io, Microsoft, Intel, Aviatrix, Huawei, IBM and others, we are excited to announce that Istio ambient mesh has graduated from the experimental branch and merged to Istio’s main branch! This is a significant milestone for ambient mesh, paving the way for releasing ambient in Istio 1.18 and installing it by default in Istio’s future releases.

GitHub-extender ZenHub may add GitLab support, claiming platforms are ‘unapproachable’ for non-technical types
ZenHub, which has built its own project management platform on top of GitHub, has enhanced its issue-tracking support. The company also told us that it hopes to support GitLab in future, having just raised US $10 million in Series A funding.
Microsoft-owned GitHub has grown rapidly in recent years. In January it reported 100 million users, more than three times as many as the 28 million counted when it was acquired in June 2018. ZenHub claims though that the platform is “unapproachable for non-technical team members and external collaborators,” according to a press release today.
containerd v1.7.0 released
The eighth major release of containerd includes new functionality alongside many improvements.
This release is the last major release of containerd 1.x before 2.0. Some functionality in this release may be considered experimental or unstable, but will become stable or default in 2.0. This release still adheres to our backwards compatibility guarantees and users who do not use or enable new functionality should use this release with the same stability expectations.
The previous 1.6 release has also become a long term stable release for users who prefer releases with mostly stability improvements and wish to wait a few releases for new functionality.
