AWS Lambda Provisioned Mode for Kafka event source mappings (ESMs) now available in AWS Asia Pacific (Taipei) and AWS GovCloud (US) Regions

24 April 2026 @ 9:13 pm

AWS Lambda now supports Provisioned Mode for event source mappings (ESMs) that subscribe to Apache Kafka event sources in the Asia Pacific (Taipei), AWS GovCloud (US-East), and AWS GovCloud (US-West) Regions. Provisioned Mode allows you to optimize the throughput of your Kafka ESM by provisioning event polling resources that remain ready to handle sudden spikes in traffic, helping you build highly responsive and scalable event-driven Kafka applications with stringent performance requirements. Customers building streaming data applications often use Kafka as an event source for Lambda functions, relying on Lambda's fully managed ESM to automatically scale polling resources in response to events. However, for event-driven Kafka applications that need to handle unpredictable bursts of traffic, lack of control over the throughput of ESM can lead to delays in your users' experience. Provisioned Mode for Kafka ESM enables customers to fine-tune the throughput of their Amazon Manag

Amazon Quick now integrates with Visier’s Vee agent for workforce intelligence

24 April 2026 @ 9:03 pm

Amazon Quick now integrates with Vee, the AI assistant from Visier's people analytics platform, through the model context protocol (MCP). HR business partners, finance managers, and operations leaders can now get governed access to live workforce intelligence from Visier directly within their Amazon Quick workspace without switching tools. After setting up the connection in Quick using Visier’s remote MCP server, you can ask questions in natural language about headcount, attrition, tenure, and open requisitions and receive answers grounded in Visier's governed workforce data model. Vee can also be invoked from automated Quick Flows to run recurring workforce reviews or draft documents. Quick intelligently routes relevant prompts to Vee and returns contextualized answers alongside enterprise knowledge – such as budgets, policies, and plans stored in Quick Spaces – so every answer reflects the full organizational picture. The Visier integration with Amazon Quick

Amazon Bedrock AgentCore Gateway and Identity support VPC egress

24 April 2026 @ 9:00 pm

Amazon Bedrock AgentCore Gateway and Identity now provide secure and controlled egress traffic management for your applications, enabling seamless communication with resources in your Virtual Private Cloud (VPC). VPC egress for AgentCore Gateway targets and Identity credential providers are offered in both managed and self-managed configurations. With VPC egress support, customers can now invoke private resources (e.g., EKS-hosted MCP servers) directly from their AgentCore Gateway. Managed VPC egress covers most customer use cases. For more complex networking setups, customers can configure their own VPC Lattice resources. AgentCore Identity VPC egress supports connectivity to Identity Providers (IdPs) running inside a customer’s VPC. This enables two key capabilities: validating inbound access tokens issued by your private IdP and fetching tokens from your IdP for outbound request authentication. Finally, this launch supports private DNS resolution for managed VPC egress

Amazon Athena simplifies federated queries with managed connectors

23 April 2026 @ 9:15 pm

Amazon Athena now offers managed connectors for 12 data sources, including Amazon DynamoDB, PostgreSQL, MySQL, and Snowflake. Managed connectors are AWS Glue Data Catalog federated connectors that Athena creates and manages on your behalf, so you can query data outside Amazon S3 without deploying or maintaining connector resources in your AWS account. With Athena, you can interactively query relational, non-relational, object, and custom data sources without moving or duplicating data. To get started with managed connectors, you create a connection for your data source in Athena. Athena automatically sets up and manages connector resources on your behalf, registering the data source as a federated catalog in AWS Glue Data Catalog. You can then query the data source alongside your Amazon S3 data and optionally set up fine-grained access controls through AWS Lake Formation. Federated queries with managed connectors are avai

AWS Client VPN now supports native AWS Transit Gateway integration

23 April 2026 @ 9:11 pm

AWS Client VPN now supports native integration with AWS Transit Gateway, simplifying centralized remote access for your end users across multiple VPCs and on-premises, and providing end-to-end source IP visibility. AWS Transit Gateway interconnects your Amazon Virtual Private Clouds (VPCs) and on-premises networks, while AWS Client VPN enables secure remote access to AWS and on-premises resources connected through your AWS network. Previously, connecting Client VPN to multiple VPCs required provisioning and managing an intermediate VPC, adding operational complexity as you needed to manage additional resources. Moreover, client source IPs were translated through Source Network Address Translation (SNAT), making it difficult to identify which remote user generated specific traffic and complicating security audits. Native Transit Gateway attachment eliminates the need for an intermediate VPC, letting you provide centralized remote access to multiple VPCs and on-premises netwo

How AI is reshaping copper, fiber networking

22 April 2026 @ 8:15 pm

Data movement over the network is more important than ever, thanks to artificial intelligence and, in particular, dedicated AI data centers. Large language model (LLM) training and AI inference require terabytes of data stored in data centers the size of football stadiums. In addition, efforts to cluster multiple sites are increasing, which means that data-center networking distances are increasing. There are two forms of network cabling: copper and fiber optics. The two technologies are very different, but they coexist in data centers. Businesses need both to operate data centers at maximum efficiency. At the recent

Cloudbase-init doesn't assign IP to Windows 2019

24 April 2026 @ 4:43 pm

I use Ansible to provision Windows VMs on VCenter and we currently evaluating cloudbase-init. With our workflow it's not possible to know the MAC of the VM before we build the VM.

AWS PA-VM with GWLB gets no packets

24 April 2026 @ 1:39 pm

I have a Palo Alto PA-VM in AWS set up for a "bump-in-the-wire" firewall for traffic in the same region but different VPC and different account with a Gateway Load-Balancer (GWLB) in between. The short version of this question: does a proper GWLB setup (same region, different accounts) for a "hairpin", "bump-on-the-wire", "north-south" traffic inspection require extra pieces (such as a TGW or other intermediary step) for packets to actually reach the firewall? Is there another technical limitation I'm overlooking? I tried this same setup in my test environment first (all in the same region using different VPCs, main difference was everything on the same account) and it worked fine. I'm cheap, so I swapped the PA-VM for a Linux EC2 at that time. The current setup will have traffic moving as follows: random internet client --> IGW (data vpc) --> VPCendpoint (data vpc, for GWLB) --> GWLB (fw vpc) -->

OVH + Proxmox IP range assigning

23 April 2026 @ 10:46 am

I purchased a failover /30 IP range from OVH for my Proxmox host server. Can I use all the IPs in that range and assign them to VMs on the host? ps: im using the default bridge setup Normally, with a /30 subnet, only 2 IPs are usable. However, in OVH’s setup, individual failover / additional IPs are provided as /32 and use the main host IP’s gateway. So does the same concept apply when purchasing a failover IP block (like a /30)? Can all the IPs in that range be assigned to VMs in the same way?

LACP vs ACTIVE_BACKUP

22 April 2026 @ 7:59 am

If LACP declaration (server side) will still send traffic when one of the NICs fails, is there any advantage to declaring a bond as one primary one slave? Other than having the backup on a financially cheaper route I cannot see any positive to it. Is there any valid technical argument in favour? I am trying to steer our automation toward LACP as a install default rather than active_backup as it is now.
