MQTT is a lightweight messaging protocol commonly used in IoT (Internet of Things) applications to enable communication between devices. As a popular open-source MQTT broker, EMQX provides high scalability, reliability, and security for MQTT messaging. By using Terraform, a widespread Infrastructure as Code (IaC) tool, you can automate the deployment of EMQX MQTT Broker on AWS, making it easy to set up and manage your MQTT infrastructure.
In part 1 of this blog series , we explored the concept of business observability, its significance, and how real-time visibility aids in making informed decisions. In part 2, we’ll show you how to retrieve business data from a database, analyze that data using dashboards and ad hoc queries, and then use a Davis analyzer to predict metric behavior and detect behavioral anomalies.
Percona University Online has released a new free course, “MySQL 5.7 End of Life Options – Free Course at Percona University Online,” by Dave Stokes, Technical Evangelist at Percona. Dave is the author of MySQL & JSON – A Practical Programming Guide. He started to work with MySQL from the 3.29 version and was a part of the MySQL Community Team for over a decade.
When you hesitate to ask for what you want or need, you aren't just missing out on immediate rewards or opportunities. You're also doing a disservice to your future self and others who might benefit from knowing what you’re after. Here's why you should nip that hesitation in the bud.
Kerberos is a secure authentication protocol for networked systems. It was developed at the Massachusetts Institute of Technology (MIT) and was first released in the 1980s. The protocol provides secure authentication of users and services, allowing them to communicate over an insecure network such as the Internet. Kerberos uses secret-key cryptography to secure communications and relies on a trusted third-party authentication server known as the Key Distribution Center (KDC).
Technology and operations teams work to ensure that applications and digital systems work seamlessly and securely. They handle complex infrastructure, maintain service availability, and respond swiftly to incidents. But when these teams work in largely manual ways, they don’t have time for innovation and strategic projects that might deliver greater value.
A join in SQL combines columns from one or more tables to extract the required data. When used effectively, joins can simplify queries and save a lot of time. In this blog, we will look into an easy way to visualize the data captured by various joins using Venn diagrams and their SQL equivalent. Some of these joins are only available natively in some relational databases; for the sake of simplicity, we will only consider the most widely used open-source databases in this blog- MySQL and PostgreS
Parallel garbage collector (Parallel GC) is one of the oldest Garbage Collection algorithms introduced in JVM to leverage the processing power of modern multi-core systems. Parallel GC aims to reduce the impact of GC pauses by utilizing multiple threads to perform garbage collection in parallel. In this article, we will delve into the realm of Parallel GC tuning specifically.

Cloud observability can bring business value, said Rick McConnell, CEO at Dynatrace. Organizations have clearly experienced growth, agility, and innovation as they move to cloud computing architecture. But without effective cloud observability, they continue to experience challenges in their cloud environments. Organizations face cloud complexity, data explosion, and a pronounced lack of ability to manage their cloud environments effectively.

Running Databases efficiently is crucial for business success Monitoring databases is essential in large IT environments to prevent potential issues from becoming major problems that result in data loss or downtime. Additionally, monitoring allows for proactive maintenance and optimization, leading to improved system performance and user experience.
Welcome to the first post in our new series exploring the world of MQTT broker clustering. If you're involved in the IoT (Internet of Things) space or have embarked on any journey involving real-time data transfer, you've probably come across MQTT (Message Queuing Telemetry Transport). MQTT is a lightweight, publish-subscribe network protocol that transports messages between devices, often known as the backbone for IoT.

Recently, I had to use Ansible to implement infrastructure as code. Initially, I used Windows Subsystem for Linux (WSL) to run the Ansible playbooks. The advantage of WSL is that it gives one a Linux shell on a Windows machine without any further ado. However, I found that WSL has this tendency to go haywire and use system resources such as CPU and RAM to the max.
In today's fast-paced financial landscape, where seamless data exchange is crucial for operational efficiency, the adoption of ISO 20022 has emerged as a global standard for financial messaging. While the advantages of ISO 20022 are widely recognized, the migration process presents numerous challenges for organizations, particularly when it comes to testing.
Functional indexes are found in both of Percona’s relational databases, MySQL and PostgreSQL, but they are probably the least used and most understood index type, aside from geospatial. You may also hear this type of index being called Index on expression. So, what is a functional index? Definitions The examples below use MySQL, but it is helpful to check their competition’s documentation to help explain what a functional index is.
Have you ever encountered situations where you want to grant a user access to all databases except a few? Or have you ever tried to revoke partial privileges from a user and you have gotten the below error message? If yes, then this article may interest you. ERROR 1141 (42000): There is no such grant defined for user username on host '%'; Recently, one of our clients requested to REVOKE partial privileges for a single database from a user having ALL the privileges for all the databases, meaning
