New observability features for your Splunk Dataflow streaming pipelines

Counter metrics are used to count messages and requests (both successful and failed) and determine the latency distribution. Distribution metrics are now used to report average request batch size and latency. Cloud Monitoring is a chargeable feature of the Splunk Dataflow template. HEC request errors are now adequately logged, including both response status code and message: "Write To Splunk" Counters #7-10 are used to track the number of successful or failed HEC requests over time and the response status breakdown to determine if the request failed due to a client request issue.

Google Cloud launches AlloyDB, a new fully managed PostgreSQL database service

AlloyDB is a new, fully managed Postgres-compatible database service. The company claims it is twice as fast for transactional workloads as AWS's Aurora Postgres. In addition, it is four times faster than standard Postgres for the same workloads and up to 100 times faster for analytical queries. As a result, Andi Gutmans, who joined Google as its GM and VP of Engineering for its database products in 2020, says customers are willing to invest resources to get off these legacy databases. Gutmans: Customers are sick of being strapped and locked in.

Benchmarking Container Scaling on AWS

I compared how tight containers scale-up under different orchestrators on AWS in 2022. ECS on Fargate is now faster than EC2, and EKS on EC2 scales shorter when using karpenter rather than cluster-autoscaler, even in the worst possible scenario. EKS is a tiny bit faster than ECS when using IPv6 and IP6. Lambda with increased limits scales ridiculously fast. EKS does a fantastic job scaling the components of Kubernetes Control Plane components (really job of scaling the 4s, which is about 280 EC2 Spot instances.

Boost your infrastructure with the AWS CDK #aws #cloud 

This guest post is by AWS Container Hero Philipp Garbe. Philipp works as Lead Platform Engineer at Scout24 in Germany. He expects that every commit automatically goes into production. The AWS CDK allows you to declare your infrastructure imperatively. The primary language is TypeScript, but several other languages are also supported. Your best practices for writing good AWS CloudFormation templates can now easily be shared within your company or the developer community. At the same time, you can also benefit from others doing the same thing.

Supercharging GitHub Actions with Job Summaries #GitHub #DevOps

GitHub Actions Job Summaries allow for custom Markdown content on the run summary generated by each job. The same familiar functionality that powers pull requests, issues, and README files have come to Actions. Users have been asking for this type of functionality for a long time. User-generated content from Actions has previously been limited to logs and annotations. We've also added a new helper utility to the @actions/core package to add Markdown Markdown to the Actions run summary page.
