AWS Config now supports internal service linked rules

2 June 2026 @ 6:00 pm

AWS Config now supports internal service linked rules, enabling AWS services to evaluate AWS resource configurations using AWS Config managed rules. Internal service linked rules extend the existing service linked recorder capability by allowing AWS services such as AWS Security Hub CSPM to deploy and manage rule evaluations for service specific functionality. With internal service linked rules, AWS services can use AWS Config managed rules to provide integrated security and compliance capabilities. Evaluation results are delivered directly to the AWS service that deployed the rule at no charge from AWS Config to customers. Internal service linked rules operate independently of existing customer managed AWS Config recorders and rules. This allows customers to continue using AWS Config for inventory, governance, compliance, and auditing use cases while AWS services independently manage service specific evaluations. AWS Security Hub CSPM internal service-linked rules

AWS Deadline Cloud now supports persistent storage for Service Managed Fleets

2 June 2026 @ 5:00 pm

AWS Deadline Cloud now supports persistent storage for Service-Managed Fleets (SMF), allowing you to maintain data across worker lifecycle events. AWS Deadline Cloud is a fully managed service that makes it easy for teams to run compute-intensive workloads in the cloud for visual effects, animation, product design, simulation, and gaming. Previously, Deadline Cloud SMF workers relied only on ephemeral storage, requiring software and assets to be reinstalled each time a worker was recycled or replaced. Now, Deadline Cloud attaches persistent Amazon Elastic Block Store (Amazon EBS) volumes to SMF workers, preserving Conda environments, Perforce workspaces, shader caches, and asset collections across worker lifecycle events. This reduces worker startup time and helps you complete jobs faster. You can configure the number of persistent volumes per worker and set a time-to-live (TTL) to control how long volumes are retained, giving you flexibility to balance storage co

Amazon SageMaker Studio now sets up in seconds with model customization ready from the start

2 June 2026 @ 4:23 pm

Amazon SageMaker Studio quick setup now completes in under twenty seconds, reduced from over two minutes. Whether you are building ML pipelines, exploring data, developing with notebooks, or fine-tuning foundation models, you can go from sign-in to a fully configured Studio environment almost instantly. As part of this streamlined setup, newly created Studio environments now come with serverless model customization permissions automatically configured. A new managed policy, AmazonSageMakerModelCustomizationCoreAccess, is created and attached for you, providing permissions for serverless model customization jobs including fine-tuning with custom reward functions for reinforcement learning, model evaluation, and deployment to SageMaker or Bedrock endpoints. This eliminates the need to manually create and configure IAM roles and policies before you can start experimenting. For existing Studio environments, actionable messages with direct links to documentation guide you throug

Amazon ElastiCache for Valkey now supports durability

2 June 2026 @ 3:00 pm

Today, AWS announces durability support for Amazon ElastiCache. Durability enables you to use ElastiCache for workloads that require microsecond read latency but cannot tolerate data loss. With durability support, ElastiCache now stores data durably across multiple Availability Zones (AZs) using a Multi-AZ transactional log to enable fast failover, database recovery, and node restarts to prevent data loss in the unlikely event of a failure. You can choose between two durability options: synchronous and asynchronous writes. Synchronous writes persist data across at least two AZs before responding to the client, designed for zero data loss at single-digit millisecond write latency. Asynchronous writes persist data after responding to the client, maintaining microsecond write latency at no additional cost. However, up to 10 seconds of uncommitted data could be lost in the rare event of a failure. Both options maintain microsecond read latency. You can now use ElastiCache for a

Amazon Location Service announces public transit and intermodal routing

2 June 2026 @ 2:51 pm

Amazon Location Service today announced support for public transit and intermodal routing in the Routes API. Developers can now use the CalculateRoutes operation with two new travel modes, Transit and Intermodal, to plan journeys that combine public transportation with walking, driving, taxi, and rental segments. With public transit routing, applications can calculate point-to-point routes using buses, subways, trains, ferries, and other transit types, including walking directions to and from stops, departure and arrival times, and transit line details. Intermodal routing extends this by combining multiple transport types in a single route, supporting common patterns such as park-and-ride (vehicle plus transit), taxi-and-ride (taxi plus transit), and last-mile completion using a taxi or rental. These capabilities help builders deliver applications across mobility, logistics, employee commute, and urban planning use cases that depend on accurate multi-modal route calculation

AWS Cost and Usage Report 2.0 now supports Athena and Redshift integration

2 June 2026 @ 1:40 pm

AWS today announced that AWS Cost and Usage Report 2.0 (CUR 2.0) provides new integration options with AWS Athena and AWS Redshift. This capability allows customers to analyze the data from their AWS CUR 2.0 in Amazon Simple Storage Service (Amazon S3) using standard SQL without building custom data warehouse solutions, bringing feature parity with CUR 1.0 integration options. With this launch, when customers select Athena or Redshift integration, CUR 2.0 exports are automatically delivered in the optimal format (Parquet, GZIP) for the chosen query engine. Each export includes the supporting metadata and automation resources needed to get started quickly, such as infrastructure templates, table definitions, and data loading instructions, so customers can begin querying their cost data without manual configuration. As CUR 2.0 data refreshes periodically, updates are automatically reflected in the Athena or Redshift tables with no additional ETL required. This featu

Amazon RDS for SQL Server supports Bring Your Own Media

2 June 2026 @ 7:00 am

Amazon Relational Database Service (Amazon RDS) for SQL Server launches Bring Your Own Media (BYOM) for Microsoft SQL Server. With BYOM, customers who migrate SQL Server applications from on-premises environments can adopt a managed database service on AWS and reuse their existing Microsoft SQL Server licenses, including Software Assurance, through Microsoft's License Mobility program. Amazon RDS provides a managed SQL Server database service that lowers operating costs with features such as high availability, automated backups and monitoring. BYOM helps customers who currently run Microsoft SQL Server on-premises, on other clouds, or as self-managed SQL Server on Amazon EC2, and want to adopt Amazon RDS and reuse their existing Microsoft SQL Server licenses. They no longer have to incur the cost of additional Microsoft SQL Server licenses, or wait for existing license agreements t

AWS HealthOmics now supports Nextflow version 26.04

1 June 2026 @ 11:00 pm

AWS HealthOmics now supports Nextflow version 26.04, enabling customers to take advantage of new Nextflow features and enhancements: record types, the strict syntax parser, workflow output summaries, and agent logging mode. AWS HealthOmics is a HIPAA-eligible service that helps healthcare and life sciences customers accelerate scientific breakthroughs at scale with fully managed bioinformatics workflows. The strict syntax parser, now enabled by default in Nextflow v26.04, helps customers save compute time and costs by enforcing strict linting, consistent block structures, and unambiguous scoping, catching issues during pipeline initialization rather than hours into workflows. Record types allow workflow developers to write workflows with meaningful data names rather than keeping track of order of tuple elements, making workflows more readable, and less error-prone. Workflow output summary in JSON format simplifies integr

AWS HealthOmics now supports Nextflow version pinning at run time

1 June 2026 @ 11:00 pm

AWS HealthOmics now allows customers to specify the Nextflow engine version at run time via the StartRun API, enabling customers to pin runs to a specific Nextflow version for controlled migration. With this launch, customers can select from supported Nextflow versions (22.04, 23.10, 24.10, 25.10, 26.04) through the new engine-settings parameter, giving explicit control at the point of execution. AWS HealthOmics is a HIPAA-eligible service that helps healthcare and life sciences customers accelerate scientific breakthroughs at scale with fully managed bioinformatics workflows. Nextflow version pinning gives customers full control over when and how they adopt new engine versions. The run-time version override ensures that even when a workflow definition specifies a version via manifest.nextflowVersion in its config or profile, the StartRun API parameter takes precedence, enabling customers to test the same workflow across mult

Quick Research now supports customer managed keys

1 June 2026 @ 6:27 pm

Amazon Quick Research now enables customers to encrypt their data using customer-managed keys (CMK) through AWS Key Management Service (KMS). This enhancement allows organizations with strict security and compliance requirements to manage their own encryption keys. With customer-managed keys, you gain enhanced security control and comprehensive audit capabilities through AWS CloudTrail integration. You can encrypt your data with your own KMS keys, trace all data access for security auditing, and revoke access to compromised keys within 15 minutes during security incidents. This feature supports multiple CMKs with one default key per AWS account per region, providing the flexibility to manage encryption across different datasets while maintaining granular control over your sensitive business intelligence data. Customer-managed keys must be created in the same AWS account and region as your Quick resources, and only symmetric AWS KMS keys are supported. This fe

Cisco brings agentic ops platform and security overhaul to Cisco Live

2 June 2026 @ 1:07 pm

Cisco built the networking infrastructure that underpins the internet and the cloud. At Cisco Live this week, the company is making its case to hold that same position as enterprises shift from AI chatbots to autonomous agents. Where chatbots answer questions, agents take actions: They execute tasks, call tools, make changes, and operate continuously at machine speed. That changes the requirements for networking, security, and observability, and it is the frame for a series of announcements. Among the key announcements from the Las Vegas event are:

Can Chinese memory maker CXMT help relieve the memory shortage?

1 June 2026 @ 7:41 pm

As the DRAM shortage continues with no end in sight, China-based ChangXing Memory Technologies (CXMT) is taking advantage of an opportunity to grow its base. Until now, CXMT has sold its products in China to lesser-known brands of memory sticks. But recently, its memory was found on a DDR5 DIMM from Corsair, a major consumer memory brand. And the company is preparing to go public, hoping to raise as much as $5 billion. CXMT is the number four memory maker in the world, behind Micron,

Broadcom, Samsung team for wireless SoC

Zero trust isn’t broken, but most companies are doing it wrong

27 May 2026 @ 4:23 pm

Zero trust is 15 years old, and like many teenagers, it can feel misunderstood and underappreciated. The concept of zero trust was first defined by John Kindervag, a Forrester analyst at the time, as a strategy to replace the outmoded perimeter security model with a “never trust, always verify” approach. But going from principle to practice isn’t easy. Accenture reports that 88% of organizations have encountered significant challeng

I am on a shared hosting server with only limited access to the Web Host manager (WHM). Therefore, I cannot make any server changes under my WHM. I do have a control panel for my account.

NFSv4: How to ensure group write permissions on new files and directories with a squashed group?

31 May 2026 @ 2:21 pm

I am running a Debian server using NFSv4 (only v4). The only expected clients are on Linux as well. I am primarilly accessing the fileserver by mounting it in fstab and using a file explorer. My exports file contains entries like this: /data/jellyfin client-hostname(rw,all_squash,anonuid=130,anongid=1002,no_subtree_check,sync) Where uid 130 is user nfs and gid 1002 is group hdd-data. The idea, then, is that the user doesn't matter, what matters is that multiple services belonging to the group hdd-data can all access and modify the files. I can upload movies to jellyfin via nfs, jellyfin can put metadata into those folders, and then I can even browse and move those files with a third, browser-based client. All of the services use system users that rely on having read+write permissions from hdd-data. This is the idea for more than just jellyfin. However, when copy over or create a new fi
