This is an article from DZone's 2023 Software Integration Trend Report.For more: Read the Report Our approach to scalability has gone through a tectonic shift over the past decade. Technologies that were staples in every enterprise back end (e.g., IIOP) have vanished completely with a shift to approaches such as eventual consistency. This shift introduced some complexities with the benefit of greater scalability. The rise of Kubernetes and serverless further cemented this approach: spinning a new container is cheap, turning scalability into a relatively simple problem. Orchestration changed our approach to scalability and facilitated the growth of microservices and observability, two key tools in modern scaling.

What Is Advertised Kafka Address?

Aggregated on: 2023-03-26 21:30:03

Let’s start with the basics. After successfully starting a Redpanda or Apache Kafka® cluster, you want to stream data into it right away. No matter what tool and language you chose, you will immediately be asked for a list of bootstrap servers for your client to connect to it. This bootstrap server is just for your client to initiate the connection to one of the brokers in the cluster, and then it will provide your client with initial sets of metadata. The metadata tells the client the currently available brokers, and which the leader of each partition is hosted by which brokers so that the client can initiate a direct connection to all brokers individually. The diagram below will give you a better idea.

ClickHouse: A Blazingly Fast DBMS With Full SQL Join Support

Aggregated on: 2023-03-24 21:30:02

ClickHouse is an open-source real-time analytics database built and optimized for use cases requiring super-low latency analytical queries over large amounts of data. To achieve the best possible performance for analytical applications, combining tables in a data denormalization process is typical. Flattened tables help minimize query latency by avoiding joins at the cost of incremental ETL complexity, typically acceptable in return for sub-second queries. However, denormalizing data isn't always practical for some workloads, for instance, those coming from more traditional data warehouses. Sometimes, part of the source data for analytical queries needs to remain normalized. These normalized tables take less storage and provide flexibility with data combinations, but they require joins at query time for certain types of analysis.

Implementing PEG in Java

Aggregated on: 2023-03-24 18:45:02

In Part 1 of the series on PEG implementation, I explained the basics of Parser Expression Grammar and how to implement it in JavaScript. This second part of the series is focused on implementation in Java using the parboiled library. We will try to build the same example for parsing arithmetic expressions but using different syntax and API. QuickStart parboiled is a lightweight and easy-to-use library to parse text input based on formal rules defined using Parser Expression Grammar. Unlike other parsers that use external grammar definition, parboiled provides a quick DSL (domain-specific language) to define grammar rules that can be used to generate parser rules on the runtime. This approach helps to avoid separate parsing and lexing phases and also does not require additional build steps.

Loop Device in Linux

Aggregated on: 2023-03-24 18:45:02

Overview If you have ever downloaded a new Linux distribution ISO image, you may have wondered how to access the contents inside the image prior to repartitioning your disk and installing the operating system onto your local disk. This can be done via a loop mount in Linux. In Linux and other UNIX-like systems, it is possible to use a regular file as a block device. A loop device is a virtual or pseudo-device which enables a regular file to be accessed as a block device. Say you want to create a Linux file system but do not have a free disk partition available. In such a case, you can create a regular file on the disk and create a loop device using this file. The device node listing for the new pseudo-device can be seen under/dev. This loop device can then be used to create a new file system. The file system can be mounted, and its contents can be accessed using normal file system APIs.

Best Practices for Setting up Monitoring Operations for Your AI Team

Aggregated on: 2023-03-24 13:15:02

In recent years, the term MLOps has become a buzzword in the world of AI, often discussed in the context of tools and technology. However, while much attention is given to the technical aspects of MLOps, what's often overlooked is the importance of the operations. There is often a lack of discussion around the operations needed for machine learning (ML) in production and monitoring specifically. Things like accountability for AI performance, timely alerts for relevant stakeholders, and the establishment of necessary processes to resolve issues are often disregarded for discussions about specific tools and tech stacks. ML teams have traditionally been research-oriented, focusing heavily on training models to achieve high testing scores. However, once the model is ready to be deployed in real business processes and applications, the culture around establishing production-oriented operations is lacking. As a consequence, there is a lack of clarity regarding who is responsible for the models' outcomes and performance. Without the right operations in place, even the most advanced tools and technology won't be enough to ensure healthy governance for your AI-driven processes.

Why Continuous Monitoring of AWS Logs Is Critical To Secure Customer and Business-Specific Data

Aggregated on: 2023-03-23 20:45:02

The Current State of AWS Log Management Security professionals have used log data to detect cyber threats for many years. It was in the late 1990s when organizations first started to use Syslog data to detect attacks by identifying and tracking malicious activity. Security teams rely on log data to detect threats because it provides a wealth of information about what is happening on their networks and systems. By analyzing this data, they can identify patterns that may indicate an attack is taking place. Migration to the cloud has complicated how security teams use log data to protect their networks and systems. The cloud introduces new complexities into the environment, as well as new attack vectors. A cloud-centric infrastructure changes how data is accessed and stored, impacting how security teams collect and analyze log data. Finally, the cloud makes it more difficult to correlate log data with other data sources, limiting the effectiveness of security analysis.

How To Perform Local Website Testing Using Selenium And Java

Aggregated on: 2023-03-23 20:45:02

Users expect new features and websites to be seamless and user-friendly when they go live. End-to-end website testing in local infrastructure becomes an unspoken critical requirement for this. However, if this test is performed later or after the entire website, or app, has been developed, the possibility of bugs and code issues increases. Such issues can do more damage than we can ever think of. According to a report by HubSpot, 88% of users are less likely to return to the website after a bad user experience. As much as $2.6 Billion is lost each year due to slow-loading websites and images on them if it takes more than an average of two seconds. Also, up to 8/10 users stop visiting a website if it is incompatible with their device. A mere look at these numbers is terrifying due to the cost and effort involved in fixing these at a later stage, in addition to the customer base lost due to bad impressions and first experiences.

Amazon CloudWatch metric alarm allows customers to watch a metric value, or a math expression value for the metric, and trigger actions when the value breaks a certain threshold limit. These alarms can be used to trigger notifications delivered via Amazon SNS, email, SMS, etc. It has been a requirement for customers to include the application log messages in the alarm notification message, so it becomes easier for operational staff to identify the root cause for the alarm notification. In this article, I will demonstrate how to embed the application log messages in the notification email body when the CloudWatch alarm is activated. Prerequisites AWS account Terraform installed and ready to use. Product Versions HashiCorp Terraform: v0.13 or later Python: v3.9 or later Node.js: 14.x or later Target Architecture The following architecture diagram shows the components involved in this solution and the interaction between them.

Container orchestration is a critical aspect of modern software development, enabling organizations to deploy and manage large-scale containerized applications. In this article, we will discuss what container orchestration is, why it is important, and some of the popular container orchestration tools available today. What Is Container Orchestration? Container orchestration is the process of automating the deployment, scaling, and management of containerized applications. Containers are lightweight, portable software units that can run anywhere, making them ideal for modern, distributed applications. However, managing containerized applications can be complex, as they typically consist of multiple containers that must be deployed, configured, and managed as a single entity.
