As companies accelerate digital transformation, they implement modern cloud technologies like serverless functions. According to Flexera , serverless functions are the number one technology evaluated by enterprises and one of the top five cloud technologies in use at enterprises. The elasticity of serverless services helps organizations scale as needed.

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. This article describes how we can protect REST APIs using Role-based access control (RBAC) in the Quarkus Java framework.

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.

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.

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).

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.

For starters, yes, Percona has chosen sides. We are a company of open source proponents. We’re also dedicated and active participants in the global open source community. But the intent here is to be informative, not to declare a winner between the two. Both open source and proprietary options have advantages. At the same time, it’s hard to ignore key differences and how they affect customers.

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.

This article outlines some of the key factors to consider while choosing whether to build or buy Incident Management software. When your organization realizes that it needs an Incident Management System (IMS), the first question is almost always, "Build or Buy?" Superficially, the requirements seem simple, and being a technical organization, you probably have the skills you need as well.

This post is a brief commentary on Martin Fowler’s post, An Example of LLM Prompting for Programming. If all I do is get you to read that post, I’ve done my job. So go ahead–click the link, and come back here if you want. There’s a lot of excitement about how the GPT models and their successors will change programming. That excitement is merited. But what’s also clear is that the process of programming doesn’t become “ChatGPT, please build me an enterprise application to sell shoes.

Even though open source software is firmly in the mainstream, used widely by businesses, governments, and everyone who owns a cell phone or computer, the question repeatedly arises: “Is open source software safe?” Broadly speaking, the answer is a resounding yes. But it’s worth examining what we mean by “safe,” contrasting open source software with proprietary software, and discussing when you should use caution.

Functional testing is a type of testing that validates the functionality of a given application feature in accordance with software requirements. The output of each function is compared with the corresponding requirement to determine whether it meets the end user's expectations. As technology evolves and rapidly transforms, the only constant remains the need for speed.

Most people are used to renting cars, but renting electric cars is a fairly new thing, so I’m sharing to help encourage people to try it out and to hopefully smooth the way with some learning and feedback ideas. We’re experienced electric car owners, and early adopters.

The test strategy is an organizational-level document that describes the general test approach, i.e., what needs to be achieved and how to achieve it. This document is outside the scope of the software testing life cycle (STLC) and does not specify testing requirements for a specific project. Instead, it establishes the common testing principles for all of the organization's projects.

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.

When you do a database restore, you want to have it done as soon as possible. In the case of disaster recovery, the situation is stressful enough on its own. And the database is unusable until the restore is done. So every minute matters. That becomes especially crucial with big datasets. Bringing physical backups in Percona Backup for MongoDB (PBM) was a big step toward the restoration speed.

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.

In software development, feature interaction occurs when the behavior of a software system is affected by the combination of features or inputs. Feature interaction can cause unexpected and undesirable behavior in software systems, which can be challenging to detect and resolve. Feature interaction matrices are one of the techniques used to identify and analyze feature interaction in software systems.
