What Is Observability? Examples of How It Can Help You

Observability is a powerful concept that can help you gain insight into the performance of your systems and applications. It refers to the ability to measure, monitor, analyze and manage different aspects of an infrastructure or application — from hardware components to application code. With observability techniques such as distributed tracing, monitoring metrics, log analysis and anomaly detection, organizations can ensure their applications run smoothly without downtime or disruption.
This blog post will explore observability and provide examples of its practical uses.

Collecting and Shipping Windows Events Logs with OpenTelemetry

OpenTelemetry’s Otel Collector simplifies monitoring Windows Event Logs, recording various operating system, process and application activities, and account activities, sending them to cloud backends such as Google Cloud.

✅ Benchmarking cheap SSDs for fun, no profit (be warned)

Low-cost SSDs may seem like a smart purchase, but one engineer found out that the tradeoff in price ultimately led to poor performance. Even though they function well regarding read performance, these inexpensive drives had atrocious write performance, demonstrating that it may be wiser to buy an expensive SSD over several cheap ones.

✅ FIFO vs. LIFO: Which Queueing Strategy Is Better for Availability and Latency?

Learn how to improve your service’s performance under heavy load with a comparative analysis of queueing strategies: FIFO, LIFO, Adaptive, and request prioritization. Explore the trade-offs with modeling and simulation.

✅ Graceful Shutdown

Graceful shutdown is essential for production systems to avoid data loss. In case of abrupt shut down of a service, the clients would get an error and could lose data. A hook function must be set to shut it down gracefully and a proper sequence of shutting down the different components of a system must be followed. It is important to maintain the buffer resources and connection in case of complex systems or multiple-level buffers that are continuously running.

An adventure with SLOs, generic Prometheus alerting rules, and complex PromQL queries

Learn about the journey we went on to craft a good developer experience around Prometheus alerts for autometrics-instrumented projects.

How to Engineer your Technical Debt Response

Technical debt, which results from poorly coded software and/or evolving requirements, can lead to system fragility and risk. It is important to measure technical debt and rank it alongside other organizational risks. Threat engineering provides an objective and quantitative approach to managing technical debt and breaking down organizational silos.

Cloud Native Skill Gaps are Killing Your Gains

Hiring cloud native experts can be challenging and expensive, but by investing in a robust training and certification program, you can bridge the gap.

ℹ️ News

Vulnerability in GCP CloudSQL Leads to Data Exposure

Research has shown that Google Cloud Platform’s CloudSQL service, which supports database engines such as MySQL, PostgreSQL, and SQL Server, has a critical vulnerability that could expose sensitive customer data. The vulnerability enables escalation of initial privilege by adding the user/dbrootrole, making it possible to bypass security barriers and gain complete control of the database engine and host. This could lead to a major security incident or a breach of sensitive data. The vulnerability was identified and fixed through the Google VRP (Vulnerability Reward Program).

Credential harvesting tool Legion targets additional cloud services

Legion hacker, a commercial malware tool, has widened its scope in targeting cloud services and can now compromise SSH servers and steal additional AWS-specific credentials, according to security firm Cado Security. The tool’s main goal is to harvest credentials and store configuration files. Attackers can also hijack resources and launch mass email and SMS campaigns, primarily through hijacked Simple Mail Transfer Protocol (SMTP) credentials. The tool also attempts to brute-force credentials to gain access to databases and web host administration panels.

Red Hat Adds Interconnect and Cybersecurity Services for Kubernetes

Red Hat expands its Service Interconnect portfolio to include the open-source Skupper.io project, adding another layer of networking for application components to run on different platforms. Red Hat also launched its managed advanced cluster security and a cloud service based on its cloud security platform after acquiring StackRox. Chris Wright, CTO and SVP of global engineering at Red Hat, says this new platform makes it easy to build and deploy secure cloud-native applications at scale.

Announcing Cloudflare Secrets Store

Cloudflare launches Secret Store for centralized and secure management of sensitive information such as API tokens, variables, and authorization headers across multiple applications and services. The tool allows administrators to restrict access and track usage through extensive audits and rotating encryption keys, among other measures. Beta testing is currently underway.

Ampere launches a new cloud native processor family with its first custom-designed cores

Ampere launches its AmpereOne family, a set of processors that are custom-designed and highly optimised for data center use cases. The new processor core is based on Arm’s Neoverse architecture and built in-house using advanced process technology. Ampere CEO, Renée James, says this is a “cloud native processor built from the ground up for a use case.”

Announcing connect() — a new API for creating TCP sockets from Cloudflare Workers

Cloudflare has announced a new API that allows developers to send outbound TCP traffic from their serverless applications to any database that speaks TCP. This will enable developers to connect to databases via standard protocol including MySQL, PostgreSQL or MongoDB, and have the vast majority of databases that require clients to connect via direct TCP sockets seamlessly connect to Cloudflare workers.
