From Monolith to Containers: Real-World Migration Blueprint

Aggregated on: 2025-06-06 14:58:09

Over the years, I’ve worked on several enterprise applications that started out as monoliths. Initially, these systems worked beautifully. Everything was packaged in a single codebase, deployment was straightforward, and communication between components was simple and efficient. But as user demand grew and development teams expanded, these same applications began to show signs of strain. Release cycles slowed, onboarding became painful, and scaling even a small feature required far too much coordination. That’s when the containerization journey began. This article is a real-world blueprint drawn from experience. It’s not just a checklist, but a practical migration story that walks through the exact stages I follow while moving from a monolith to containers. I’ll also reflect on the challenges and insights I’ve picked up along the way.

Managing Encrypted Aurora DAS Over Kinesis With AWS SDK

Aggregated on: 2025-06-06 14:58:09

When it comes to auditing and monitoring database activity, Amazon Aurora's Database Activity Stream (DAS) provides a secure and near real-time stream of database activity. By default, DAS encrypts all data in transit using AWS Key Management Service (KMS) with a customer-managed key (CMK) and streams this encrypted data into a Serverless Streaming Data Service - Amazon Kinesis. While this is great for compliance and security, reading and interpreting the encrypted data stream requires additional effort — particularly if you're building custom analytics, alerting, or logging solutions. This article walks you through how to read the encrypted Aurora DAS records from Kinesis using the AWS Encryption SDK.

Automating Kubernetes RBAC Sync With LDAP Entitlements Using Python

Aggregated on: 2025-06-06 14:58:09

In enterprise Kubernetes environments, particularly those supporting data science and analytics teams, managing namespace access becomes increasingly complex as user roles and responsibilities evolve. Teams often rely on centralized identity platforms like LDAP or Active Directory, where group entitlements define access rights. However, Kubernetes lacks native integration with LDAP, which forces teams to maintain RoleBindings manually — a tedious, error-prone, and unscalable process. This exact challenge emerged in our organization, where dozens of data scientists and engineers needed timely, accurate access to shared Kubernetes namespaces. We were stuck managing access through a manual process involving support tickets, group membership checks, and handcrafted YAML RoleBindings. It was slow, insecure, and operationally painful.

Maximizing Cloud Cost Efficiency: Intelligent Management of Non-Production Environments

Aggregated on: 2025-06-06 14:58:09

In the fast-paced world of cloud computing, organizations continually seek ways to optimize their infrastructure spending. One of the most overlooked areas of potential cost savings lies in non-production environments, specifically the development, staging, and testing landscapes. Organizations transitioning to the cloud often carry over habits from traditional data centers, where maintaining multiple environments had minimal cost. This mindset persists despite the different cost dynamics in cloud environments. There are also misconceptions about resource management. For instance, many believe databases can't be stopped without risking data loss. However, modern cloud technologies allow for efficient start-stop operations, state persistence, and rapid environment restoration. Unlike mission-critical production infrastructure that requires constant availability, non-production environments can be dynamically managed with minimal friction and maximum cost efficiency.

The Synergy of Security and Development: Integrating Threat Models With DevOps

Aggregated on: 2025-06-06 14:58:09

In our digital-first world, security isn't just important — it's non-negotiable, especially within DevOps environments. Yes, DevOps brilliantly accelerates development by bridging the gap between development and operations teams. But here's the catch: that impressive speed sometimes races past essential security checkpoints. That's why weaving threat modeling directly into your DevOps workflow isn't just smart — it's necessary to spot and neutralize security threats before they become problems. IBM's 2024 Cost of a Data Breach report demonstrates that the global average cost of a data breach in 2024 is 4.88M USD, which is a 10% increase over last year and the highest total ever. What do these eye-opening statistics tell us? Simple: weaving security into your DevOps isn't optional — it's critical. Beyond just shielding you from devastating data breaches, DevSecOps actually turbocharges your development cycle, trims unnecessary spending, and takes your product quality to new heights.

Beyond Bytecode: Exploring the Relationship Between JVM, JIT, and Performance

Aggregated on: 2025-06-03 14:13:08

In computing, the execution of programs written in high-level languages requires that the source code be compiled to a low-level or native language. This compilation is referred to as Ahead-of-Time (AOT) and is typically done during build time. Effectively reducing the work to be done during runtime. In case of Java, the AOT produces an intermediate binary, viz. bytecode, which is then translated to native machine code during execution by the Java Virtual Machine (JVM). This is in line with Java’s philosophy of Write-Once-Run-Anywhere (WORA), or simply put, platform independence.

Domain-Centric Agile Modeling for Legacy Insurance Systems

Aggregated on: 2025-06-02 21:13:07

Legacy insurance systems have accumulated decades of complexity in their codebases and business logic. This complexity is spread across batch jobs and shaped by regulation, rather than architecture. Directly applying modern Agile modeling to such a landscape often throws developers off track and into frustration. That is where Agile can work, but only when recentered around the realities of the domain. A domain-first perspective is captured by the fact that success in these environments cannot be achieved by providing screens and endpoints but by replicating the essence of how the business operates.

Enterprise Data Loss Prevention (DLP) Security Policies and Tuning

Aggregated on: 2025-06-02 18:13:07

I’ve worked with a lot of enterprise customers over the years—big ones, too—and a common struggle I see is with their Data Loss Prevention (DLP) policies. Even though they’ve had the product for years, they often face one of two issues: either the policies are too weak and don’t flag anything, or they’re too strict, overwhelming teams with false alerts. When DLP policies aren’t properly tuned, it creates gaps that can lead to business disruptions and even huge losses. A well-known example is NASA’s ITAR email filtering issue in 2019, where an excessively strict DLP policy blocked legitimate emails, grinding operations to a halt. While there are many such cases, enterprises rarely disclose disruptions caused by poor policy design. The stakes are simply too high—reputation, confidential information, and, most importantly, customer trust are all on the line. Because of this, companies are often reluctant to seek external help in refining their security policy infrastructure, even when expert guidance could prevent costly mistakes. Ultimately, security software vendors play a crucial role in simplifying policy tuning, ensuring enterprises can strike the right balance between protection and usability.

From Hype to Harm: Why AI Governance Needs More Than Good Intentions

Aggregated on: 2025-06-02 16:13:07

The race to implement AI technologies has created a significant gap between intention and implementation, particularly in governance. According to recent data from the IAPP and Credo AI's 2025 report, while 77% of organizations are working on AI governance, only a fraction have mature frameworks in place. This disconnect between aspirational goals and practical governance has real consequences, as we've witnessed throughout 2024-2025 with high-profile failures and data breaches. I've spent the last decade working with organizations implementing AI solutions, and the pattern is distressingly familiar: enthusiasm for AI capabilities outpaces the willingness to establish robust guardrails.

Observability Expenses: When ‘Pennies on the Dollar’ Add Up Quickly

Aggregated on: 2025-06-02 12:13:07

I’ve specialized in monitoring and observability for 27 years now, and I’ve seen a lot of tools and techniques come and go (RMon, anyone?); and more than a few come and stay (rumors of the death of SNMP have been – and continue to be – greatly exaggerated). Lately I’ve been exploring one of the more recent improvements in the space – OpenTelemetry (which I’m abbreviating to “OTel” for the remainder of this blog). I wrote about my decision to dive into OTel recently: "What’s Got Me Interested in OpenTelemetry—And Pursuing Certification". For the most part, I’m enjoying the journey. But there’s a problem that has existed with observability for a while now, and it’s something OTel is not helping. The title of this post hints at the issue, but I want to be more explicit. Let’s start with some comparison shopping.

Designing Embedded Web Device Dashboards

Aggregated on: 2025-06-02 11:13:07

Overview A web dashboard serves as the “front panel” for an embedded product — whether that product is a rack-mounted industrial controller, a bike-mounted GPS tracker, or a battery-powered soil-moisture sensor buried in a greenhouse bed. Because the dashboard is delivered over plain HTTP(S) and rendered in any modern browser, users do not have to download a native app, install drivers, or worry about operating-system compatibility; the interface is as portable as a URL. Typical tasks include: Toggling outputs (relays, MOSFETs, LEDs) Inspecting live data such as temperature, humidity, current draw, or RSSI Adjusting parameters like Wi-Fi credentials, alarm set-points, sampling rates Collecting diagnostics like log files or memory statistics for field support staff Implementation Approaches Embed an HTTP server — Mongoose, lwIP-HTTPD, MicroPython’s uHTTPD, or a hand-rolled socket handler - inside the firmware. Then choose, or mix, the patterns below. Each technique sits at a distinct point on the scale of resource cost versus user-experience richness.

Resolving Parameter Sensitivity With Parameter Sensitive Plan Optimization in SQL Server 2022

Aggregated on: 2025-05-30 15:13:05

For years, database administrators and developers working with SQL Server faced a persistent performance issue known as parameter sniffing. This problem arises because SQL Server’s traditional query plan caching mechanism generates only a single execution plan for a parameterized query. That plan is based on the parameter values used during the query's first execution. While efficient in many cases, this behavior leads to significant performance degradation when parameter values vary widely in terms of their data selectivity or distribution. For example, a plan optimized for a parameter value that filters a small subset of rows can be reused for a parameter that retrieves millions of rows, causing inefficient scans and resource overuse.

This article explores how to secure an Angular + Node.js application end-to-end (frontend, backend/API) and embed security into the CI/CD pipeline with DevSecOps practices. We’ll include code snippets (like input validation and JWT auth) and diagrams for a secure architecture and pipeline.

When Airflow Tasks Get Stuck in Queued: A Real-World Debugging Story

Aggregated on: 2025-05-29 18:13:05

Recently, my team encountered a critical production issue in which Apache Airflow tasks were getting stuck in the "queued" state indefinitely. As someone who has worked extensively with Scheduler, I've handled my share of DAG failures, retries, and scheduler quirks, but this particular incident stood out both for its technical complexity and the organizational coordination it demanded. The Symptom: Tasks Stuck in Queued It began when one of our business-critical Directed Acyclic Graphs (DAGs) failed to complete. Upon investigation, we discovered several tasks were stuck in the "queued" state — not running, failing, or retrying, just permanently queued.

Monoliths, REST, and Spring Boot Sidecars: A Real Modernization Playbook

Aggregated on: 2025-05-29 17:28:05

Forget the idea that modernization has to mean rewriting everything. The real work happens in the in-between, where REST meets SOAP, where sidecars live beside WAR files, and where code changes are political before they're technical. Especially in high-stakes, compliance-bound environments like healthcare, government, and labor systems, modernization doesn’t look like a revolution. It looks like a careful negotiation.

What’s Got Me Interested in OpenTelemetry—And Pursuing Certification

Someone (I don’t remember who. If it was you, feel free to take credit in the comments) once told me, “If you want to break a habit, don’t tell anyone. If you want to build a habit or achieve a goal, tell everyone.”

ACID vs BASE: Transaction Models Explained

Aggregated on: 2025-05-29 15:28:05

There are two main approaches to handling transactions: either we follow ACID or BASE principles. All other approaches are just variations of the two; we can even say that, to a certain degree, BASE is a variation of ACID. Furthermore, some databases may pick to support ACID transactions for part of operations, while not providing the same quarantine for others – just like MongoDB here. In today’s text, I will cover the description of both abbreviations, and their use cases, closing with an in-depth summary of the differences between them. For now, let’s say that the biggest difference between the two is: that ACID prioritizes consistency over availability, while BASE prioritizes availability over consistency.

Introducing Graph Concepts in Java With Eclipse JNoSQL, Part 3: Understanding Janus

Aggregated on: 2025-05-29 14:28:05

Graph databases are increasingly popular in modern applications because they can model complex relationships natively. Graphs provide a more natural representation of connected data from recommendation systems to fraud detection. Our previous articles explored graph databases broadly and delved into Neo4j. In this third part, we focus on JanusGraph, a scalable and distributed graph database. Unlike Neo4j, JanusGraph supports multiple backends and leverages Apache TinkerPop, a graph computing framework that introduces a standard API and query language (Gremlin) for various databases. This abstraction makes JanusGraph a flexible choice for enterprise applications.

Building a Real-Time Change Data Capture Pipeline With Debezium, Kafka, and PostgreSQL

Aggregated on: 2025-05-29 13:28:05

Change Data Capture (CDC) is a foundational pattern in modern data engineering. It enables systems to react to database changes in near real-time by streaming inserts, updates, and deletes as events. This capability is critical in a wide range of scenarios: synchronizing microservices, feeding real-time dashboards, updating machine learning features, powering audit logs, or building streaming data lakes. In this tutorial, we’ll walk through how to implement a CDC pipeline using the following components:
