Deployment is the day when the software is finally released to the world. Yet, as Stackify CEO Matt Watson said, organizations lack confidence in deployment. One of the greatest strengths of agile is the ability to deploy rapidly. However, moving too fast and without following the right processes, one can witness problems like downtime, errors, and poor user experience.

Ruchir Jha , Brian Harrington , Yingwu Zhao TL;DR Streaming alert evaluation scales much better than the traditional approach of polling time-series databases. It allows us to overcome high dimensionality/cardinality limitations of the time-series database. It opens doors to support more exciting use-cases. Engineers want their alerting system to be realtime, reliable, and actionable.

eBPF has many uses in improving computer security, but just taking eBPF observability tools as-is and using them for security monitoring would be like driving your car into the ocean and expecting it to float. Observability tools are designed have the lowest overhead possible so that they are safe to run in production while analyzing an active performance issue.

If we were to select the most important MySQL setting, if we were given a freshly installed MySQL or Percona Server for MySQL and could only tune a single MySQL variable, which one would it be? It has always bothered me that “out-of-the-box” MySQL performance is subpar: if you install MySQL or Percona Server for MySQL in a new server and do not “tune it” (as in change default values for configuration settings), it just won’t be able to make the best use of the serve

“Set it and forget it” is the approach that most network teams follow with their authoritative Domain Name System (DNS). If the system is working and end-users find network connections to revenue-generating applications, services, and content, then administrators will generally say that you shouldn’t mess with success. Unfortunately, the reliability of DNS often causes us to take it for granted.

Optimize cost and availability while staying compliant Observability data like logs and metrics provide automated answers, root cause detection, and security issues. Customer decisions about data retention are often determined by important security, privacy, and legal issues. Customers must comply with internal and external policies and regulations that might demand them to keep specific data stored for a minimum period of time (for example, audit logs).

Indexes are generally considered to be the panacea when it comes to SQL performance tuning, and PostgreSQL supports different types of indexes catering to different use cases. I keep seeing many articles and talks on “tuning” discussing how creating new indexes speeds up SQL but rarely ones discussing removing them. The urge to create more and more indexes is found to be causing severe damage in many systems.

REST APIs are the heart of any modern software application. Securing access to REST API s is critical for preventing unauthorized actions and protecting sensitive data. Additionally, companies must comply with regulations and standards to operate successfully.

There was a comment on Twitter today from Rafael Gonzaga expressing disappointment in what he sees as a tendency to focus on the frontend solely in performance discussions, while neglecting the server-side aspect. In the discussion that followed, the Golden Rule of Performance (popularized by Steve Souders) was brought up: 80-90% of the end-user response time is spent on the frontend.

The primary metric for memory bandwidth in multicore processors is that maximum sustained performance when using many cores. For most high-end processors these values have remained in the range of 75% to 85% of the peak DRAM bandwidth of the system over the past 15-20 years — an amazing accomplishment given the increase in core count (with its associated cache coherence issues), number of DRAM channels, and ever-increasing pipelining of the DRAMs themselves.

Traditionally, cloud-resource management is done by collecting telemetry data for critical-capacity resources and configuring multi-level reactive alerting (warnings, errors, and critical errors) for those resources. While the traditional approach to cloud-resource management might have been acceptable in the past, it doesn’t scale up to address the requirements of modern cloud environments.

Developers, architects, and application teams are constantly chasing technical debt. For better or worse, it’s a nagging problem that too often gets kicked down the road until it’s too late and application development slows down, new features slip, test cycles increase, and costs ramp up. In the most public situations, the applications tip over completely — like we’ve seen most recently at Southwest Airlines, Twitter, FAA, and others which never get publicized — but you know who you are.
