How to Solve Context Propagation Challenges in Distributed Tracing

Distributed tracing allows tracking of a specific flow as it progresses throughout microservices systems. With distributed tracing, developers can connect the dots and gain visibility and understanding of a certain flow. This saves time when building and operating modern applications.

However, not all workflows and architectures support distributed tracing mechanisms. This is the case especially when these mechanisms were built as creative and customized solutions to unique situations. In such cases, it can be challenging to implement the context propagation mechanism, which is responsible for gathering the metadata that enables building the distributed tracing flow.

3 Reasons Why You Should Centralize Developer Tools, Processes, and People

Have you ever worked for an organization that uses 15 overlapping tools, all with different requirements, inputs, and administrators? Pretty hectic, right? Every development team has its unique blend of tools that help it ship code, but it’s hard to keep all those tools seamlessly working together. We recently surveyed developer teams, and they cited fragmented tools as the most common challenge, with 39% of respondents calling it a significant challenge. 

The decentralization of developer tools, processes, and people creates friction in software development workflows and frustration across teams. If you feel like you’re constantly shifting between tools or searching for information and wasting time to ineffective tools, you’re not alone — but you also don’t have to suffer any longer. Here’s a closer look at some common issues and potential solutions:

5 Benefits of Electronic Data Interchange

The world of corporations can be difficult if you are not moving with the pace of the industry. Having a solid communication channel while aligning with other organizations is one of the crucial aspects of the business today. While there was a time when maintaining accurate records and keeping the communication fast was a challenge for many organizations, today, EDI solutions have made it super easy for them.

Electronic data interchange has been one of the most required technologies that have simplified the basic data transfer and communication among two partnered organizations. You see, companies can't handle everything on their own. There are operations that companies prefer to keep in-house, while there are tasks that need to be outsourced. Partnering with other niche organizations is a great way to maintain quality in the operations. However, the basics of such collaborations depend majorly on the quality of communication that these two have.

Data Mesh — Graduating Your Data to Next Level

Data Mesh is fast emerging as a serious architecture pattern to look for in the field of data. I will stop after saying 'field of data' rather than extending the 'data' to data science, data engineering, data warehouse, and all such kinds of buzz words. We in IT have the habit of creating buzzwords and then following them. I just want to focus on something other than just the buzzword. The reason for this is Data Mesh has the potential to completely change the way we handle and look at our data. This will have an impact on all areas where data is the critical element.

Report Card For Current Level of Data

Before we graduate our data to the next level, here is a quick summary of progress or a report card of the current level of data. The diagram below shows how data is normally handled in today's IT systems.

Tutorial: Build a Simple Rust App and Connect It to ScyllaDB NoSQL

ScyllaDB, an open-source database for data-intensive applications that require high performance and low latency, is an excellent match for Rust. Similar to the Rust programming language and the Tokio framework, ScyllaDB is built on an asynchronous, non-blocking runtime that works well for building highly-reliable low-latency distributed applications.

The ScyllaDB team has developed the scylla-rust-driver, an open-source ScyllaDB (and Apache Cassandra) driver for Rust. It’s written in pure Rust with a fully async API using Tokio. You can read more regarding its benchmark results, plus how our developers solved a performance regression.

Java’s Encapsulation - When the Getter and Setter Became Your Enemy

Encapsulation is the key to a good code design, but how to archive it? Java developers automatically think about putting getter and setter in a private attribute. 

The encapsulation is a wrapping up of data under a single unit. It is the way to protect the data with OOP and avoid any security issues. The main idea around encapsulation is the data's guardian or a shield from being accessed by the code outside this shield when it makes sense.

To Shift Right, You Need Observability

In a world of shifting left, there is a growing movement: to shift right.  I recently attended a panel discussion where the panelists (from tech companies in this space) debated and even insisted – that shifting right will actually allow you to deliver more value to your customers.  Then, as they laid out their arguments, one thing became clear:  In order to shift right without significant risk, you need extensive observability of your entire application stack.

Shifting Left vs. Shifting Right

First, what does it mean to shift left or right?  Well, the shift-left movement came out of something we've known for many years: if you find a problem earlier, it costs less to fix it. The idea is to encourage your developers to do extensive testing, verify functionality in multiple levels of pre-production environments, and catch every issue you possibly can before it goes out to production.

Applying Domain-Driven Design Principles to Microservice Architectures

Microservices are the most scalable way of developing software. But you need a good design that lets developer teams work autonomously and deploy without stepping on each other's toes; otherwise, you lose most of the scalability benefits.

Domain-Driven Development allows us to plan a microservice architecture by decomposing the larger system into self-contained units, understanding the responsibilities of each, and identifying their relationships. In this article, we'll learn the basics of Domain-Driven Design and how to apply it to microservices.

Many companies are looking to low-code and no-code platforms to build apps in the visual environment. They provide the opportunity for faster app development and reduce the dependence on highly skilled developers. Companies may hire less experienced or only minimally trained staff (I’ll call them citizen developers) to meet service gaps and to respond to skills shortages, ensuring their larger dev team can focus on more advanced projects.

Demystifying Cloud-Native Data Management: Layers of Operation

As containerized applications go through an accelerated pace of adoption, Day 2 services have become a here-and-now problem. These Day 2 services include data management functions such as backup and disaster recovery along with application mobility. In this new world of containerized cloud-native applications, microservices use multiple data services (MongoDB, Redis, Kafka, etc.) and storage technologies to store state and are typically deployed in multiple locations (regions, clouds, on-premises).

In this environment, where legacy infrastructure or hypervisor-based solutions don’t work, what are the right constructs for designing and implementing these data management functions for cloud-native applications? How should you reason about the various data management options provided by storage vendors, data services vendors, and cloud vendors to decide the right approach for your environment and needs? This piece dives under the covers and addresses the pros and cons of various data management approaches across several attributes including consistency, storage requirements, and performance.

Monolith vs Microservices architecture: Split or Not to Split?

What Is a Microservice Architecture and Why It Is Often Chosen

Currently, the software paradigm is represented by two types of solutions: microservices and monolithic architecture. In general, microservices architecture represents an application as a collection of small, loosely coupled services. In this kind of solution, the complexity is moved to the level of coordination of services. Each service represents one business capability that makes it easier to locate the code.

Whereas monolithic architecture assumes several discrete functions composed into a single unit that is tested, deployed, and scaled as a whole. All components are interdependent and often cannot run separately. That also means a bug in a module can slow down or break the entire application.

Making Your Own Express Middleware

Express is a common way to display static routes to a user. It is even more commonly used to create APIs for Node.JS. In Express, it's easy to define a URL and what will happen at that URL. We can also define middleware, which runs before the final request is returned. This can let us to alter the request and do it in a standard way across many routes.

If you've used Express, you may have already used pre-built middleware like bodyParser or jsonParser. In this guide, let's look at how you can create your own custom middleware.

How Template Literal Types Work in TypeScript

Template Literals are common in JavaScript: they let us easily combine variables and strings in JavaScript. TypeScript also introduces the concept of Template Literal Types, where we can enforce types on the inputs for Template literals. That gives us controls to ensure that text is in a certain format. Let's look at how they work.

Template Literal Types in TypeScript

A perfect example of when a template literal type might be useful is for creating IDs of certain formats. For example, let's say we have an ID that starts with 'ga-' or 'ua-', followed by a string or number. We can define a new type using type literals for that like so:

What Is Data Analytics? Understanding Data Analytics Techniques

Data is becoming increasingly crucial for success in the digital economy. You might ask, why do organizations rely so much on data? Well, a majority of organizations rely on data for multiple processes, from product management and fraud detection to HR, finance, and manufacturing. Data analytics allow users to use pre-made reports to track performance metrics on demand. Research shows that 94% of organizations believe that data and analytics solutions are critical for growth. Not a surprising statistic since it offers several benefits, including an increase in productivity and efficiency, faster and more effective decision making, and financial gains!  

Before we dive into the ins and outs of data analytics, it is important to understand the two terms, namely ‘data science’ and ‘data analytics. Data science lays emphasis on finding meaningful correlations between large datasets, while data analytics is a branch of data science designed to uncover specifics of extracted insights

However, when decision-makers invest in those technologies, they want the assurance of well-designed products that meet their expectations. The people designing IoT sensors are primarily responsible for creating functional, safe, cost-effective products. Here are some vital things to remember as a sensor designer or someone trying to select the most appropriate products to buy.

Power Sources

Many IoT sensors receive power from wall outlets or have built-in rechargeable batteries. However, those solutions aren’t feasible for some connected sensors applications.

Working with Salesforce APIs? Of CORS!

The fundamental capabilities of the internet can be boiled down to one simple interaction: a call and a response. One machine (the client) sends requests to another machine (the server), which responds with a reply. This back-and-forth request-and-response cycle is how every phone, television, smart fridge, or computer sends and receives data.

However, there are several security risks inherent in this model, from application vulnerabilities to DDoS attacks. In this post, we’ll take a closer look at how Cross-Origin Resource Sharing, or CORS, mitigates these risks and how it operates. By working with a small Node.js app that interacts with several Salesforce APIs, we will see the differences in responses when CORS is enabled and disabled, as well as what effect it has on our client.

8 Reasons the Consequences of Bad Data Are More Severe

You may not have heard the term data downtime, but I’m willing to bet you’ve experienced it and the cost of bad data firsthand.

Urgent ping from your CEO about “missing data” in a critical report? Duplicate tables wreaking havoc in your Snowflake warehouse, all titled some variation of “Mikes_Table_GOOD-V3.”? Or, perhaps you’ve unintentionally made a decision based on bad data from last year’s forecasts?

What Is Pair Programming?

When it comes to software development, writing high-quality and defect-free source code is imperative. In order to ensure or improve the quality of the source code developers write, they carry out a variety of tasks, including code reviews, error checking, iterative loops, linting, and fast feedback. 

However, developers perform all these activities once they write code. What if you get all these activities done simultaneously while writing the source code line by line? Wondering how it is possible? Yes, it is possible with the help of pair programming.

How Does the Internet Speed Test Work?

Everyone deserves the right internet speed and everyone wants the best bang for a buck. To ensure our internet bandwidth, we all run speed tests from our Internet Speed Provider or public speed test tools like fast.com or speed.cloudflare.com and more. But do we know how the speed got measured under the hood? In this blog post, we will see how the Internet Speed Test works?

What Is an Internet Speed Test?

The Internet Speed Test helps us to understand how fast our internet connection is. It is primarily based on Download and Upload speed, usually measured in megabits per second (Mbps), but varies based on which tool you are using. One megabit is equal to 1,024 kilobits.

How to Reduce Cloud Cost by 99% for EDA Kafka Applications

While the cloud offers great convenience and flexibility, the operational cost for applications deployed in the cloud can sometimes be significant. This article shows a way to substantially reduce operating costs in latency-sensitive Event-Driven Architecture (EDA) Java applications by migrating from Kafka to Chronicle Queue open-source, a more resource-efficient and lower-latency queue implementation.

What Is EDA?

An EDA application is a distributed application where events (in the form of messages or DTOs) are produced, detected, consumed, and reacted to. Distributed means it might run on different machines or the same machine but in separate processes or threads. The latter concept is used in this article whereby messages are persisted in queues.

Can This Ownership Exercise Improve How You Work with Others?

When you’re working in a group, you need to know how to coordinate. Coordination requires a shared understanding of how everyone will work together. Most human groups define Roles. Roles help clarify boundaries and expectations for people working together.

For example, in sports, these roles are called Positions. To play well, you need all the positions to understand how to work with each other. And you need everyone to focus on their position. It would be ridiculous in football (aka soccer) to have everyone try and be the goalkeeper.

Deploying Java Applications to AWS Elastic Beanstalk

I have been studying Amazon Web Services, and I realized deploying Java applications on Amazon Elastic Beanstalk (EB) is a little different from deploying apps that do not require compilation to run. So this took a lot of my time and I decided to share a simple example of deploying a Java application to Elastic Beanstalk by using Amazon CDK. We can also do this in lots of different ways such as using EB CLI, but I am going to talk about deploying by using CDK CLI.

Create Your Application

Before starting, you can check the repository that includes completed SpringBoot and CDK projects on GitHub.

First, we need to create a simple Spring boot app, you should add the Spring Web package while you are creating this. You can initialize a spring boot project from here if you do not have IntelliJ Idea Ultimate. After initializing the project, you should build your application to a jar:

Delegating JWT Validation for Greater Flexibility

In my opinion, the purpose of all software applications that have been created so far, are being and will be developed should primarily be to make humans' day-to-day activities easier to fulfill. Humans are the most valuable creations, and software applications are great tools that at least could be used by them.

Nowadays, almost every software product exchanges data with at least one other peer software product, which results in huge amounts of data flowing among them. Usually, a request from one product to another needs to pass a set of preconditions before it is considered acceptable and trustworthy.

Implementing Microservices Architectures

This article aims to give you an overview of the concepts surrounding microservices and event-driven architecture, which should help you make informed decisions about whether you should go for a microservices architecture or not.

What Are Microservices?

Besides being a buzzword, microservices represent an application that is divided into multiple smaller applications. Each application, or microservice, interacts with the others to create a scalable system. Usually, microservices are deployed to the cloud as containerized or serverless applications.

Event-Driven Microservices?

When Vikas Anand, Product Director of Google’s Apigee API Management offering, gave the presentation "The Case for a Unified API and Event Strategy" during the recent EDA Summit of 2022, I was again shocked by a gleaming error in what was presented: “Microservices, while they’re providing a great deal of advantages, they also bring in complexity which you need to manage. We can basically manage this better by providing a solution which is called event-driven architecture. This produces a solution for this problem, of microservices and a solution at scale, where it provides the ability to reduce dependencies and complexities in your application, whilst still allowing the creation of more and more microservices.”

Although I genuinely have no idea what any of that means, an error was nonetheless evident in the associated slide:Event driven architecture slide from Vikas Anand presentation

Kubernetes as Sustainability Tool

A wise man once said “We used the cloud for our digital transformation. Why not use it for a sustainability transformation as well?” (Adrian Cockcroft, VP Amazon Sustainability Architecture 2021). 

All major cloud providers have undertaken significant efforts to improve the sustainability of the cloud but the ultimate responsibility for sustainable use in the cloud is on us as a tech community. Theoretically, Kubernetes allows for highly precise resource utilization and minimal cloud waste. But in reality, there are many good reasons why we have not yet reached this goal.

Build a Quarkus Reactive Application Using Kubernetes Secrets

Many organizations have security policies in place that dictate how to store sensitive information. When you're developing applications for the cloud, you're probably expected to follow those policies, and to do that, you often have to externalize your data storage. Kubernetes has a built-in system to access external secrets, and learning to use that is key to a safe cloud-native app.

In this article, I'm going to demonstrate how to build a Quarkus reactive application with externalized sensitive information—for instance, a password or token—using Kubernetes Secrets. A secret is a good example of how cloud platforms can secure applications by removing sensitive data from your static code. Note that you can find a solution to this tutorial in this GitHub repository.

Scalable Writes to Postgres With Spring

Every engineering organization that strikes a chord with customers eventually runs into scaling issues. Scaling a product and an organization puts new demands on both your processes and your infrastructure. In this post, we highlight how our company tackled one of many infrastructure scaling challenges: Scalable writes to the (Postgres) database using Spring & Spring Data.

As we grew our userbase, we began to run into some performance issues, primarily bottlenecked by our upstream Postgres database. Our RPS went over 180 (from < 50) in just a few months, and we started running into problems like SQL connection timeouts, dropped connections, and significantly increased latency. This led to a degraded customer experience, which was unacceptable.

Continuous Delivery: Create Products Faster with Lower Risks

DevOps methodology continues to strengthen its position in programming. So-called “continuous” tools are among the most commonly used in the field. Such practices as Continuous Integration and Continuous Delivery allow you to constantly keep your code delivered into production as soon as any changes are made. This makes it possible to add new features in progress and fix the bugs on the go, as you work with small chunks of code, which are easy to operate. CI/CD methodology of software development brings reliability and speed to product creation, allowing it to hit the market faster. 

CI is the first stage of the CI/CD technique. There are a lot of benefits of Continuous Integration implementation in your project. It is an essential process of a software update, and its primary function is to integrate code changes from various developers into a single information repository.

Agile for Web Development: Is It Really What Your Team Needs?

Have you been considering using another approach to your web development process? If you have been an avid user of the waterfall method, you must be aware of agile procedures. Changing from waterfall to agile can sound a little scary because no one can predict if it will work for you. However, see it as something that must be implemented and tested a few times until your team finds how to make it work perfectly. 

But how to know if a change to agile is genuinely what your company needs? Sadly, there is no short guide that you can answer to discover if you’re ready to follow the three laws of agile. Nevertheless, we want to explain the difference between agile and waterfall methods, the benefits of using agile, and how to succeed if you use this methodology in your business.

DevOps vs. SRE — Their Differential Impact on Building Efficiency and Reliability

The software development life cycle has come a long way - from a non-overlapping development model - the Waterfall Model, to an iterative development model like Agile and DevOps. It’s interesting to notice that before the beginning of the DevOps movement (~2007-2008), SRE was born at Google (2003) to build the reliability and resiliency of the entire Google Infrastructure. In its SRE book, Google described how the collaborative efforts of DevOps engineers, SRE, and other engineers like Application Security engineers are vital for maintaining a product like Gmail.

Looking at the above example, it is safe to say that our growing dependency on applications has propelled the widescale adoption of DevOps and SRE. Whether it’s to streamline our business functionalities or launch an app that simplifies our life, we need reliable and scalable systems at every step.
