<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Version 7.0 of HashiCorp's Terraform Google Cloud provider adds features such as ephemeral resources for temporary credentials and write-only attributes to prevent sensitive data from being written to state files. The update, which recently surpassed 1.4 billion downloads and supports over 800 resources, focuses on improved validation logic and API alignment, potentially requiring users to update their Terraform configurations.

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Datadog used Cloud Cost Management to centralize visibility of cloud expenses and collaborated between FinOps and engineering to identify storage inefficiencies. Implementing optimized S3 storage classes and lifecycle rules reduced costs, generating an estimated $1.5 million in annual savings while creating a system to discover future opportunities.

<strong>Migrate to Amazon EKS: Data plane cost modeling with Karpenter and KWOK (7 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Organizations can simulate Kubernetes migrations to Amazon EKS using Karpenter and KWOK to observe node provisioning, optimize costs, and estimate compute requirements without launching real EC2 instances. The process involves backing up the source cluster with Velero, creating a destination EKS cluster, deploying Karpenter with KWOK for virtual nodes, restoring workloads, and analyzing resource allocation for accurate cost modeling.

</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">

</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
