Kanban, a well-known agile framework, has significantly influenced project management and software development. With its roots in Japanese manufacturing practices, Kanban has evolved to meet the changing needs of modern software development. This article explores Kanban's principles, history, benefits, and potential drawbacks and compares it with other agile methodologies. It also discusses tools for implementing Kanban.

Kanban, which means "visual signal" or "card" in Japanese, is a workflow management method designed to optimize workflow. It was developed in the late 1940s by Toyota engineer Taiichi Ohno as a scheduling system for lean manufacturing. The application of Kanban to software development began in the early 2000s, providing a more flexible approach to managing software projects.

Machine Learning specialists are at the forefront of the digital transformation of the global economy today; they face a rapidly evolving technology environment that requires a wide range of professional skills. The role of an ML Engineer tasked with transforming theoretical data science models into scalable, efficient, and robust applications can be especially demanding. A professionally savvy ML Engineer has to combine proficiency in programming and algorithm design with a deep understanding of data structures, computational complexity, and model optimization.

However, there is a pressing issue in the field: many ML Engineers have critical gaps in their core competencies. Despite mastering essentials like a working knowledge in Classical ML, Deep Learning and proficiency in ML frameworks, they often overlook other vital, even indispensable, areas of expertise. Nuanced programming skills, a solid understanding of mathematics and statistics, and the ability to align machine learning objectives with business goals are some of such areas.

Due to the surge in large language model adoption in the Enterprises, GENERATIVE AI has opened a new pathway to unlock the various business potentials and use cases. One of the main architectural building block for GENERATIVE AI is the semantic search powered by the Vector database. Semantic search, as the name suggests is, essentially involves a "nearest neighbor" (A-NN or k-NN) search within a collection of vectors accompanied by metadata. This system having an index to find the nearest vector data in the vector storage is called Vector Database where query results are based on the relevancy of the query and not the exact match. This technique is widely used in the popular RAG (Retrieval Augmented Generation) pattern where the a similarity search is performed in the Vector database based on the user's input query, and the similar results or relevant information is augmented to the input of an Large Language Model so that the LLM doesn't hallucinate for a query outside of its knowledge boundary to generate an unique response for the user. This popular GENERATIVE AI based pattern called, RAG can't be implemented without the support of Vector database as one of the main core component in the architecture. Because of more and more increase in GENERATIVE-AI use cases, as an engineer working on transitioning an LLM-based prototype to production, it is extremely crucial to identify the right vector database during early stage of development. 

During the proof-of-concept phase, the choice of database may not be a critical concern for the engineering team. However, the entire perspective changes a lot as the team progresses toward the production phases. The volume of Embedding/vectors data can expand significantly as well as the requirement to integrate the security and compliance within the app. This requires a thoughtful considerations such as access control and data preservation in case of server failures. In this article we will explain a framework and evaluation parameters which should be considered while making the right selection of the Enterprise grade Vector database for the GENERATIVE-AI based use case considering both the Developer Experience as well as the technological experience combining into the Enterprise experience. We also need to keep in mind that numerous vector db products are available in the markets with closed or open source offering and, each catering to a specific use case, and no single solution fits all use cases. Therefore, it's essential to focus on the key aspects when deciding the most suitable option for your GENERATIVE AI based application.

How We Used to Handle Security

A few years ago, I was working on a completely new project for a Fortune 500 corporation, trying to bring a brand new cloud-based web service to life simultaneously in 4 different countries in the EMEA region, which would later serve millions of users.

It took me and my team two months to handle everything: cloud infrastructure as code, state-of-the-art CI/CD workflows, containerized microservices in multiple environments, frontend distributed to CDN, and tests passing in the staging environment. We were so prepared that we could go live immediately with just one extra click of a button. And we still had a whole month before the planned release date.

Have you heard of GraphQL? This API query language, initially developed by Facebook (now Meta), has evolved into a thriving ecosystem. Explore this article to understand why embracing this new API paradigm is essential.

Complex Software Engineering Poses New Challenges

API Schema

When managing traditional REST APIs, tools like OpenAPI or Postman are typically employed to handle API schemas. This approach, independent of the API itself, relies entirely on the developer's knowledge and expertise in deciding whether to provide these descriptive files and how to do so correctly.

PostgresML is an extension of the PostgreSQL ecosystem that allows the training, fine-tuning, and use of various machine learning and large language models within the database. This extension turns PostgreSQL into a complete MLOps platform, supporting various natural language processing tasks and expanding Postgres's capabilities as a vector database.

The extension complements pgvector, another foundational extension for apps wishing to use Postgres as a vector database for AI use cases. With pgvector, applications can easily store and work with embeddings generated by large language models (LLMs). PostgresML takes it further by enabling the training and execution of models within the database.

Resilience refers to the ability to withstand, recover from, or adapt to challenges, changes, or disruptions. As organizations increasingly embrace the microservices approach, the need for a resilient testing framework becomes important for the reliability, scalability, and security of these distributed systems. MRTF is a collaborative, anticipatory, and holistic approach that brings together developers, quality assurance professionals, operations teams, and user experience designers. In this article, I delve into the key principles that underpin MRTF, exploring how it integrates into a cohesive framework designed to navigate the intricacies of microservices testing.

What Is MRTF?

The Microservices Resilient Testing Framework (MRTF) goes beyond the surface, examining the intricate interactions between microservices, considering the entire ecosystem, and anticipating future challenges in microservices development. From preemptive problem-solving to the continuous iteration of testing practices, MRTF encapsulates a comprehensive approach that ensures microservices architectures are rigorously tested for reliability, scalability, and overall user satisfaction. In embracing a holistic and collaborative approach, let’s start by explaining the cornerstones of MRTF.
