🧪 Amazon Kinesis Data Streams now integrates with AWS Fault Injection Service (FIS) to simulate Kinesis API errors and validate application error handling, retry logic, and monitoring. Customers can induce throttling, internal errors, service unavailable, and expired iterator exceptions—covering 500, 503, and 400 responses for GET and PUT operations—to test resilience and CloudWatch alarms. FIS experiments support templates, CI integration, and automatic stop thresholds to keep tests controlled, and are generally available in all Regions where FIS is offered, including AWS GovCloud (US).

⚙️ This post introduces the fundamentals of chaos engineering and explains why deliberately injecting controlled failures helps teams build more resilient cloud-native systems. It covers core principles — such as defining a steady-state hypothesis, limiting blast radius, replicating realistic failure modes, and automating experiments — and translates them into practical steps for experiment design, fault injection, probing, and rollback. The article recommends using Chaos Toolkit and points to Google Cloud–specific recipes to help engineers begin safely and iteratively.

🛡️ Modern disaster recovery and business continuity require a ground-up rebuild to address distributed data, evolving cyberthreats, climate-driven disruptions, and strict breach-reporting obligations. Key elements include executive sponsorship, standing interdisciplinary teams, AI-assisted discovery and classification, continuous and immutable backups aligned with a 3-2-1-1-0 approach, and the design of a minimum viable business to restore core functions. Frequent, gamified tabletop exercises and automated validation complete a resilient program.

🔒 Ineffective recovery processes and increasingly sophisticated ransomware are driving adoption of Cyber Recovery approaches that isolate and validate backups before restoring systems. Modern platforms combine immutable snapshots, sandboxed restores, and automated forensics with AI/ML-based detection to identify safe restore points and reduce downtime. Vendors highlighted include Acronis, Cohesity, Commvault, Dell, Druva, Rubrik, Veeam, Zerto.

⚙️ Amazon EBS now provides a latency injection action in AWS Fault Injection Service (FIS) to simulate degraded I/O performance on EBS volumes as part of controlled fault injection experiments. The action reproduces real-world signals such as Amazon CloudWatch alarms and OS timeouts so teams can observe application behavior and validate recovery. Pre-defined templates are available in the EBS and FIS consoles, and experiments can be customized or combined with other actions to integrate into chaos engineering and CI workflows. The capability is available in all Regions where FIS is supported.

🪂The SOC is framed as the parachute organisations rely on when breaches occur. Too many SOCs are under‑specified and reactive—drowned in alerts and tools that add complexity rather than resilience. The author calls for Swiss engineering: over‑specified, tested processes, rehearsed responses, and anticipatory defence grounded in threat modelling and behavioural context. Vendors and AI can assist, but organisations must own priorities, rehearse decision making, and build muscle memory.

🧪 AWS announced that Fault Injection Service (FIS) is now available in the Europe (Zurich) Region. FIS is a fully managed service for running controlled fault injection experiments to validate application performance, observability, and resilience under scenarios such as AZ power interruptions and cross-region connectivity failures. Customers can create reusable experiment templates, integrate them into CI/CD pipelines, and generate detailed experiment reports stored in Amazon S3 for audit and compliance needs. This launch expands FIS to 24 regions globally.

🛡️ Organizations face escalating operational risk as threat actors leverage optimized supply chains, pre-packaged services and AI to accelerate attacks and social engineering. Managed detection and response (MDR) is promoted as a prevention-first approach that prioritizes speed of detection, containment and response. Best-in-class MDR combines 24/7 monitoring, proactive threat hunting and automated compliance and forensic reporting to reduce downtime and support recovery.

🚀 This Cloud Next 2025 talk explains how to build fault-tolerant, multi-region services using Cloud Run, highlighting autoscaling, decoupled control/data planes, and N+1 zonal redundancy. The post previews an upcoming Service Health feature that automates cross-region failover by relying on container readiness probes and minimum-instance settings. It also outlines deployment patterns (global external ALB with Serverless NEGs) and shows a live demo of automated traffic failover.

🔒 In a world where pandemics, war, and natural disasters are inevitable, security teams must plan for continuity. The article examines two primary approaches: scaling VPN capacity for remote access or adopting a SASE framework that integrates networking and security as a cloud-delivered service. Each option has trade-offs in cost, complexity, and operational risk; readiness requires assessing user patterns, threat exposure, and recovery objectives.

🔧 Amazon announces that Aurora DSQL now integrates with AWS Fault Injection Service (FIS) to enable controlled resilience testing for applications that depend on Aurora DSQL. Customers can simulate regional connectivity disruptions and full inaccessibility to validate failover, reconnection, and recovery behaviours across single-Region and multi-Region deployments. Experiment templates can be included in CI pipelines and FIS generates detailed reports that can be stored in Amazon S3 for auditing and compliance. The capability is available in multiple AWS Regions.

🛠 AWS now supports resilience testing for S3 Express One Zone using AWS Fault Injection Service (FIS), enabling simulated network disruptions that cause data plane requests to timeout for directory buckets. The FIS network disruption action is included in the AZ Availability: Power Interruption scenario and is available in all Regions where the storage class is offered. You can run experiments via the AWS Management Console, AWS CLI, or the FIS API to validate monitoring, recovery procedures, and improve application resilience; consult FIS pricing for cost details.

🔐A DEF CON 33 panel argued that while digital tactics like misinformation and cyberattacks can disrupt systems, they rarely win wars on their own. Panelists emphasised that cyber effects tend to be temporary, whereas kinetic attacks inflict longer-lasting physical damage. Using a Taco Bell supply-chain analogy and real incidents such as Change Healthcare, the discussion urged organisations to map dependencies and build resilience to mitigate third-party risk.

📢 CISA, in partnership with SAFECOM and NCSWIC, released an updated Emergency Communications System Lifecycle Planning Guide and companion Lifecycle Planning Tool on July 2, 2025. The suite refreshes the 2011 and 2018 materials and incorporates public safety practitioners' experiences to inform system build, maintenance, operation, decommission, and replacement decisions. The Lifecycle Guide offers recommendations and the Lifecycle Planning Tool provides checklists for each lifecycle phase. Resources and funding guidance are aligned to help jurisdictions plan technology upgrades.
