Do not be confused about the following introduction. This post *is* about app-enabled folders. But before explaining what they are and how you can make one, it is important to quickly refresh what the term “folder” means in the context of Google Cloud.

If you have used Google Cloud you know about Google Cloud projects. According to Google Cloud resource hierarchy, any service resource (e.g. a virtual machine, GKE cluster or IP address) has a project as their parent, which represents the first grouping mechanism of the Google Cloud resource hierarchy. When a user accesses Google Cloud using an organizational account ‒ a Google Workspace account issued by an organization’s administrator, they have access to additional levels of grouping: folders and the topmost ‒ organization. Of course all access is pending appropriate IAM permissions. Folders allow to group projects and other folders to abstract company’s organizational or production hierarchies and control access to underlying resources.
Users can also access Google Cloud using personal accounts ‒ free accounts for individuals, created to access Google services like Gmail, Drive, and more. However, these accounts limit access to resource hierarchy to the level of projects and its underlying service resources.

OpenTelemetry (OTel) is the go-to standard for monitoring applications, offering a vendor-neutral way to capture telemetry data like traces, metrics, and logs. This enables consistent instrumentation and avoids vendor lock-in. Developers widely use OTel to instrument applications, with exporting telemetry data to Google Cloud Observability services.

OTel’s native data format follows OTLP (standing for OpenTelemetry Protocol) standard. To export OTel data to Google Cloud usually requires exporters like Google Cloud Trace Exporter for Go that exist for most of the popular programming languages.

DISCLAIMER: This post is not about log storage billing or managing log sinks.

Have you ever read or heard the phrase “Write everything to logs”? This is good advice. You never know what information can be useful or when. It is easy to do in Google Cloud. With help of audit logs all infrastructure, security and other cloud internal events are stored in Cloud Logging. And you can write application logs by simply printing them to stdout. However, there are situations when you may need to prevent some log entries from being stored:

Google Cloud provides efficient and not expensive storage for application and infrastructure logs. Logs stored in Google Cloud can be queried and analyzed using the analytical power of BigQuery. However, there are scenarios when Google Cloud customers may need to export log data from Google Cloud to third party (3P) solutions. This post reviews two main use cases of log exporting: exporting already stored logs and exporting logs while they are being ingested. The post focuses on how to configure and implement the part of the exporting process that handles extracting logs from Google Cloud. The part of loading the data into 3P solutions is not explored because of the variety of requirements and constraints that different 3P solutions expose.

PromQL stands for Prometheus Query Language. This post is about using PromQL in Cloud Monitoring. PromQL provides an alternative to the Metrics Explorer menu-driven builder and Monitoring Query Language (MQL) interfaces for exploring metrics, creating charts and alerts. Google Cloud introduced support for PromQL at the same time as Managed Service for Prometheus. Later, support for PromQL was introduced in Monitoring alert management. Practically it means that you can use PromQL instead of Monitoring Query Language (or MQL) to query Cloud Monitoring metrics in the Metrics Explorer, in custom dashboard configurations, and in alert management.

What is context caching?

Vertex AI is a Google Cloud machine learning (ML) platform that, among other things, provides access to a collection of generative AI models. This includes the models known under the common name “Gemini models”. When you interact with these models you provide it with all the information about your inquiry. The Gemini models accept information in multiple formats including text, video and audio. The provided information is often referred to as “context”. The Gemini models are known to accept very long contexts.

Production systems are being monitored for reliability and performance tracking to say the least. Monitored metrics ‒ a set of measurements that are related to a specific attribute of a system being monitored, are first captured in the executing code of the system and then are ingested to the monitoring backend. The selection of the backend often dictates the methods(s) of ingestion. If you run your workloads on Google Cloud and use self-managed Prometheus server and metric collection, this post will help you to reduce maintenance overhead and some billing costs by utilizing Google Cloud Managed Service for Prometheus for collecting and storing Prometheus metrics.

If you do not care about how much money you spend on your Google Cloud project then this post won’t be interesting to you. If you do, you might find the information below useful.

Google Cloud documentation gives examples of the automated cost control responses. It describes an option to send a notification message to PubSub in addition to the email each time the billing budget alert is triggered.

Everyone today heard or read about GenAI, ChatGPT and other AI things. There are a lot of terminology, abbreviations and other clever words. I found myself troubled to remember all of them. So I decided to write down my definitions for each of these terms.

TL;DR; If you are familiar with AI terminology, you might want to stop reading this post here. For the rest of the readers, welcome to my personalized thesaurus of GenAI terminology.

This article surveys various health checks in Google Cloud. If you want to learn more, leave your preferences in the feedback form.

Generally speaking, a health check is a function or a method to indicate a general state (a.k.a. health) of the underlying service. Some products elaborate the definition of “general state” to be something particular, such as the ability of the service to respond to requests.

Health checks are an important instrument of service observability. When provided as a tool or service they replace development of coding metrics ingestion, collection and analysis. Health checks often come integrated with alerting or incident response solutions. In many scenarios health checks can be sufficient to increase product reliability to desired level.
