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.

Data-at-rest encryption is essential for compliance with regulations that require the protection of sensitive data. Encryption can help organizations comply with regulations and avoid legal consequences and fines. It is also critical for securing sensitive data and avoiding data breaches. PostgreSQL does not natively support Transparent Data Encryption (TDE).

“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.

A module can be something as simple as a bug fix, a story, or something more extensive such as adding a new feature or third-party option to a system.

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.

Eighteen months ago, I wrote that there is a good case to be made that the tech cycle is more economically significant than the credit cycle. By way of example, customer-facing tech and corporate collaboration technology contributed far more to robust S&P 500 earnings during the pandemic than the Fed’s bond buying and money supply expansion. Having access to capital is great; it doesn’t do a bit of good unless it can be productively channeled.
