### AI overview

This article introduces a series about choosing Red Hat edge platforms for specific deployment needs. It compares Red Hat Enterprise Linux and Red Hat OpenShift across workload types, platform sizes, hardware requirements, Kubernetes use cases, availability, storage, and management needs.

### Source excerpt

Choosing the right platform for an edge deployment is one of the most consequential decisions an organization makes--and one of the most confusing. The options range from a single-board computer running a handful of containers to a full Kubernetes cluster with high availability, software-defined storage, and centralized management. Pick too small, and you hit a wall when requirements grow. The post Red Hat edge platforms: Choosing the right one for your use case appeared first on Red Hat Developer.

### AI overview

This tutorial explains how to enable TLS for replication traffic in Percona XtraDB Cluster without a full cluster restart. Using Galera's socket.dynamic option, operators can perform two rolling restarts: first allowing encrypted and plaintext connections, then enforcing TLS-only communication.

### Source excerpt

Starting with Percona XtraDB Cluster (PXC) 8.0, replication traffic encryption is enabled by default. That said, it's common to find clusters running without TLS that suddenly need it: a new compliance requirement, an audit finding, a network segment that is no longer considered trusted. PXC has a variable for exactly that case, pxc-encrypt-cluster-traffic, which handles ... Continued The post Enabling TLS in PXC without Downtime appeared first on Percona.

### AI overview

Razorpay reduced daily metrics ingestion from about 450 billion to about 170 billion samples, cutting its metrics bill by 62% without deleting useful dashboards or breaking alerts. The article describes an audit conducted during a planned migration from a self-hosted VictoriaMetrics cluster to a managed monitoring platform, covering scrape intervals, duplicate high-availability scrapes, and high-cardinality metrics.

### Source excerpt

Contributor: Saijal Shrivastava We cut our metrics ingestion by 62% without deleting a single useful dashboard or breaking an alert. Daily ingestion dropped from about 450 billion samples to about 170 billion. The surprising part was not one large optimization. It was three simple discoveries hiding in plain sight: Scrape intervals can multiply ingestion. High-availability scraping can silently send duplicate metrics when deduplication happens only at the storage layer. High-cardinality metrics are easy to create, expensive to keep, and hard to remove without ownership. We found these while preparing to move from a self-hosted VictoriaMetrics cluster to a managed monitoring platform. The migration started as a reliability project. The audit turned it into a cost and signal-quality project. We were not just moving monitoring data. We were moving years of accumulated assumptions about what was worth scraping. The Incident that Forced the Audit Our self-hosted VictoriaMetrics cluster had served us well for years. Then one storage node hit EBS volume throttling. Traffic shifted to the remaining storage nodes, the extra load pushed another node past its limits, and the storage layer collapsed. We saw the same pattern whenever a storage node became unavailable: traffic redistributed, the remaining nodes overloaded, and the cluster moved back toward failure. The collection, ingestion, and query components were still running, so the system looked alive from the outside. But the storage layer was down. Metrics stopped being persisted. Dashboards went blank. Alerts stopped evaluating. Recovery took hours. Teams fell back to logs and manual checks to understand production health. Figure 1: Cascading failure in the pipeline That made the reliability problem obvious. We needed a more stable monitoring architecture. We evaluated several options: self-hosted designs with disaster recovery built in, and fully managed alternatives. But when we priced the managed options, one number

### AI overview

This beginner-oriented article explains load balancing as both traffic distribution and backend failure detection. It compares round robin and least-connections algorithms, distinguishes Layer 4 from Layer 7 routing, and discusses health checks, failover, draining, sticky sessions, and the risks of overly aggressive checks.

### Source excerpt

Spreading traffic is the easy half of load balancing. The half that decides whether an outage lasts ten seconds or ten minutes is noticing that a backend has stopped working, and most health checks cannot.

DigitalOcean has placed Managed Weaviate into public preview. The service provides fully managed Weaviate clusters with automated backups, security patching, version upgrades, high availability, and storage autoscaling, with pricing starting at $20 per month.

### Source excerpt

Production Weaviate in minutes, managed by DigitalOcean. Starting at $20/month. Vector databases have become a core piece of the AI application stack. Whether you're building retrieval-augmented generation (RAG), semantic search, agentic workflows and memory, or similarity-based recommendations, you need a vector store that's reliable, fast, and doesn't require a dedicated ops engineer to keep running. Weaviate has become a critical part of that stack -- its open-source AI-native vector database powers semantic search, RAG, and agentic workflows for thousands of companies. Self-hosting Weaviate is doable but it comes at a cost. You're on the hook for backups, version upgrades, security patches, high availability configuration, and storage scaling. That's real time and real engineering capacity that isn't going toward your product. Managed alternatives from larger cloud vendors exist, but they often come with per-query fees, per-dimension surcharges, and pricing models that are difficult to predict as usage grows. Today, we're announcing that Managed Weaviate is now in public preview on DigitalOcean, offering an easy way for you to run Weaviate in production, at a price that makes sense from day one. The easiest way to run Weaviate in production Managed Weaviate on DigitalOcean handles the operational work so you don't have to. Provision a fully managed Weaviate cluster directly from the DigitalOcean control panel. From there, automated backups, security patching, version upgrades, high availability, and storage autoscaling are handled for you. Full Weaviate client compatibility via GraphQL, REST, and gRPC on port 443 means your existing code works without modification. This means you get Weaviate's full capabilities -- semantic and hybrid search, RAG pipelines, and support for agent-driven workflows -- without spending engineering time on the infrastructure beneath them. Predictable pricing, starting at $20/month We built Managed Weaviate with flat, predictable monthly

### AI overview

Keycloak 26.7.0 introduces preview support for SCIM-based user provisioning and simplified multi-cluster high availability, along with enhanced HAProxy and Traefik reverse-proxy guidance and step-up authentication for SAML clients. The release also adds a more secure, OAuth 2.0-compliant Identity Brokering API v2, while V1 remains enabled by default but is deprecated. OID4VCI improvements remain experimental.

### Source excerpt

To download the release go to Keycloak downloads. Highlights This release features new capabilities for users and administrators of Keycloak. The highlights of this release are: Automate user provisioning with the SCIM API (preview) Simplified multi-cluster high availability without external caches (preview) Enhanced reverse proxy guides with blueprints for HAProxy and Traefik Step-up authentication for SAML clients Read on to learn more about each new feature. If you are upgrading from a previous release, also review the changes listed in the upgrading guide. Security and Standards Stronger security for the Identity Brokering API The Identity Brokering API allows applications to retrieve tokens obtained from external identity providers during federated login. Version 2 of this API replaces the legacy V1 with a more secure and standards-compliant design: Client-level authorization -- access to external tokens is controlled per client using dedicated settings (Allow retrieve external tokens and an identity provider allow list) instead of assigning broker roles to individual users. Confidential clients only -- public clients are rejected, ensuring that only authenticated clients can retrieve external tokens. OAuth 2.0 compliant -- the endpoint uses POST and returns standard JSON responses with access_token, error, and error_description fields. Session-based token storage -- a new Store token in session option keeps tokens in the user session for faster access, with automatic cleanup on session expiry. Database storage remains available for persistence across sessions. V2 is now supported but disabled by default. V1 is deprecated but still enabled by default for backward compatibility. In a future release, V1 will be removed and V2 will become the default. For more information, see the Identity Brokering APIs chapter in the Server Developer Guide. Progress on Verifiable Credentials (OID4VCI) (experimental) Verifiable Credentials (OID4VCI) allow organizations to issue tampe

### Source excerpt

Are you considering replatforming your SQL Server workload due to recent vendor changes, but still need high availability and disaster recovery? You're not alone. One of the challenges with running SQL Server on Kubernetes is that there's no Kubernetes operator available. That means no automated lifecycle management, no automatic failover, and no standard way to bootstrap an Always On Availability Group on Kubernetes. I'm excited to share it today as an open-source project: sql-on-k8s-operator. Let's go.
