EdgeX Foundry on K3s (Part 2): The Initiation

Aggregated on: Sun Dec 05 2021 19:04:13 GMT+0000 (Coordinated Universal Time)

In the first part of this series, we have seen all the pre-requisites that are needed to proceed with the hands-on. We will extend the EdgeX Foundry tutorial by Jonas Werner and deploy the EdgeX Foundry services on K3s. We have already learned that K3s will be a good lightweight solution to manage and orchestrate the EdgeX microservices. We will use the Geneva version of EdgeX Foundry. The scope of this post is to demonstrate an Edge use case that will consume the sensor data e.g. ambient temperature. This sensor data will then be processed by EdgeXFoundry services hosted on K3s. This sensor data will be pushed to a cloud-based MQTT broker called HiveMQ. From here, the data can be stored and processed in the cloud. The configurations and manifests used in these posts are available in this repository.

EdgeX Foundry on K3s (Part 1): The Inception

Aggregated on: Sun Dec 05 2021 18:34:13 GMT+0000 (Coordinated Universal Time)

Why Emphasize the Edge? As we start using edge computing in its true sense, I think we are approaching the edge of the technological renaissance. The Edge is becoming an essential element of all the upcoming and futuristic technologies. Some of the popular examples would be as shown in Fig. 1: Edge is a complementary solution to 5G. Edge is the backbone for IoT and Fog. Edge is required for AI and ML workloads to enable real-time data processing. Automated vehicles leverage the Edge for mission-critical latency and high reliability. VR applications need the Edge for stringent requirements of latency, network, and reliability. Edge will conserve broadband networks while streaming global events. Software upgrades can use the Edge to minimize network pressure on backhaul. Fig. 1 - Showing the 5G stack The major issues which are common in all the above areas are minimum latency requirement and high network availability. These two issues are exacerbated in the case of traditional cloud-based architectures as it is a centralized architecture. Edge plays an important role in alleviating the two pressure points by distributing data processing, thus being an essential part of all the technologies.

Introduction The healthcare industry is one of the largest in the world, and it is intimately linked to human life and has a significant impact on individual lives. Healthcare refers to the diagnosis and treatment of disease, illness, and other physical and mental disabilities in people. What Is Healthcare Domain Testing? Healthcare domain testing is one of the most important domains in which we test a healthcare domain application to see if it fits the domain's requirements and to check for many factors such as standards, security, conformance, and cross dependency with other entities. The main purpose of healthcare domain testing is to ensure that the product is of high quality, easy to operate, and effective.

Your Code-First API Needs Validation

Aggregated on: Sun Dec 05 2021 17:49:13 GMT+0000 (Coordinated Universal Time)

When you start a project, you might tend to do code first API as this is a well-known territory for most developers, especially with frameworks like Spring Boot, which uses powerful annotations to generate your API and specifications. In a matter of a few lines, you have a simple CRUD API up and running. But that’s not the end of the story, people need to consume it next. And as they are looking at consuming your API the first thing they will turn to is your documentation, specification, and associated testing UI.

In computer science, there is nothing more fundamental than control structures. Every student learned about them in the first few weeks of any computer science program. We could not code without them, period. But they are not set in stone: we did get rid of the infamous GOTO in the 80s! At the pre-ALGOL meeting held in 1959 Heinz Zemanek explicitly threw doubt on the necessity for GOTO statements; at the time no one paid attention to his remark, including Edsger W. Dijkstra, who later became the iconic opponent of GOTO.[3] The 1970s and 1980s saw a decline in the use of GOTO statements in favor of the "structured programming" paradigm, with goto criticized as leading to "unmaintainable spaghetti code"

Observability: It’s Not What You Think

Aggregated on: Sun Dec 05 2021 17:19:13 GMT+0000 (Coordinated Universal Time)

What Is Observability? Observability is a mindset that enables you to answer any question about your entire business through the collection and analysis of data. If you ask other folks, Observability is the dry control theory definition of “monitoring the internal state of a system by looking at its output,” or it’s the very technical definition of “metrics, traces, and logs.” While these are correct, Observability isn’t just one thing you implement, then proudly declare “now this system has Observability™.” Building Observability into your business lets you answer questions about your business. What Kind of Questions? Of course, the basic “what happened in our app when this error count spiked up” questions can be answered with Observability tools, but that’s barely scratching the surface of what Observability actually is. What an Observability mindset lets you do is to figure out why the error count spiked up. If you’re intimately familiar with your app and all of its dependencies, then perhaps you can get this insight from a monitoring system, but as modern apps become increasingly more complex, the ability to maintain the state of them in your head becomes more and more challenging. Business demands, feature launches, A/B tests, refactoring into microservices… things like this all combine to create ever-increasing entropy, so knowing everything about your system without help gets more difficult by the day.

Role of TechOps, DevOps, and NoOps in the SDLC

Aggregated on: Sun Dec 05 2021 17:19:13 GMT+0000 (Coordinated Universal Time)

The process of product development and software deployment has continually evolved to meet the requirements for speed (increasing demand) and for scalability, and enhanced efficiency (quality of product). Tech companies must constantly learn, unlearn, and adapt to meet changing demands to bring a viable product to market as quickly as possible. Previously, IT departments appeared to be centralized teams, but recently, popular operational concepts have been initiated on organizing your IT teams to meet your needs more efficiently. Based on these concepts, IT teams have been structured into specialized departments with distinct roles and outcomes, albeit working collaboratively. Some of these prevailing concepts include TechOps, DevOps, and NoOps.

Building a Better Notification System [Video]

Aggregated on: Sun Dec 05 2021 16:49:13 GMT+0000 (Coordinated Universal Time)

Today, we’re going to talk about building a modern product notification system. This talk’s really intended for engineers, product managers, anyone working for a product organization that needs to send notifications and messages to their users, and maybe is thinking about where and how they need to be building that over the next 6 months, 12 months, 18 months as their product and organization evolve. By the end of this, we’re hoping to really give you enough to get started thinking about what improvements you might want to make to your notification infrastructure or what notifications you want to send that you’re not sending today and how you should think about building and maintaining those systems moving forward. We are putting together a white paper that’ll be available soon. So take a look at that if you want to dig into even more detail than what we cover in this discussion. So when we think about a modern product notification system, we need to think about what are the requirements, right? And what we’re going to walk you through is a few of the ways we think about it when we work with our customers and what we hear about from our customers that may have already built their own product notification system before they met Courier. Here’s the way I normally like to break it down is between requirements that are for the development team: Right? The team that’s building and maintaining these notifications and these messages, and the requirements that are really for more of the product management team, the design team, the marketing team, and support team, those that maybe aren’t directly responsible for building this infrastructure, but who really rely on this infrastructure to power a lot of the activities and objectives that they’re trying to achieve with their projects with the product.

The Science of Productive Role Conflict

My first major encounter with a role conflict occurred when I took on a team lead role. It was a critical project that required integration across multiple teams and functions and consisted of a few senior people who were pulled in temporarily from other teams to help meet the delivery timelines. While we were all responsible for implementation, I was additionally required to strategize, plan and coordinate the entire deliverable. That’s where things got a little bit complicated. My role to successfully deliver the project conflicted with the expectation to manage people who were senior to me:

Best Practices For GraphQL Security

Aggregated on: Sun Dec 05 2021 02:19:13 GMT+0000 (Coordinated Universal Time)

While GraphQL enables the creation of flexible APIs, it is considered prone to allow malicious queries that compromise application servers. Being one of the most popular query languages, commonly found vulnerabilities make GraphQL Security a topic of consistent deliberation, assessment, and flaw mitigation. In this blog post, we delve into various GraphQL vulnerabilities, best practices to mitigate risks and address some commonly asked questions. What is GraphQL? GraphQL is a server-side runtime, API query language that prioritizes returning only the data that clients request. The language is intended to make APIs lightweight, flexible, developer-friendly, and fast. GraphQL lets development teams craft requests that access data from multiple sources in a single interface call, making it an alternative to the REST API framework. The language can be deployed within an Integrated Development Environment (IDE) and provides a syntax that describes how users should ask for data. GraphQL offers a framework that operates predictably while allowing developers to build APIs with their chosen methods.

Improving the Reader Experience With Adobe Embed API

Aggregated on: Sat Dec 04 2021 17:04:13 GMT+0000 (Coordinated Universal Time)

The Adobe PDF Embed API provides a simple way for web developers to display PDFs on their web pages. While browsers provide good support for rendering PDFs, they do so in an "out of context" manner that takes over the entire screen. The PDF Embed API however lets you place a PDF within your site's layout, providing much better control over the position and size of the rendered document. This improved experience also provides deeper integration into the PDF viewer, letting developers listen for events and perform operations on the document. In this article, I'm going to demonstrate a simple, but hopefully really useful example of this. Imagine a large document covering many pages, for example, a textbook. Your website users, potentially students, could work with the document over many weeks while school is in session. If the document is a few hundred pages long, it would be incredibly useful to remember where they were in the document when they start reading again. While a large PDF may have bookmarks, even then they could only be for chapters or other sections, not the exact page the user last read. Luckily, the Embed API provides a method to help with this. Let's take a look!

Why Choose FastAPI over Flask?

Aggregated on: Sat Dec 04 2021 11:19:13 GMT+0000 (Coordinated Universal Time)

To help you quickly get started with Milvus, the open-source vector database, we released another affiliated open-source project, Milvus Bootcamp on GitHub. The Milvus Bootcamp not only provides scripts and data for benchmark tests, but also includes projects that use Milvus to build some MVPs (minimum viable products), such as a reverse image search system, a video analysis system, a QA chatbot, or a recommender system. You can learn how to apply vector similarity search in a world full of unstructured data and get some hands-on experience in Milvus Bootcamp. We provide both front-end and back-end services for the projects in Milvus Bootcamp. However, we have recently made the decision to change the adopted web framework from Flask to FastAPI. This article aims to explain our motivation behind such a change in the adopted web framework for Milvus Bootcamp by clarifying why we chose FastAPI over Flask. Web Frameworks for Python A web framework refers to a collection of packages or modules. It is a set of software architecture for web development that allows you to write web applications or services and saves you the trouble of handling low-level details such as protocols, sockets, or process/thread management. Using a web framework can significantly reduce the workload of developing web applications as you can simply "plugin" your code into the framework, with no extra attention needed when dealing with data caching, database access, and data security verification. For more information about what a web framework for Python is, see Web Frameworks. There are various types of Python web frameworks. The mainstream ones include Django, Flask, Tornado, and FastAPI. Flask Flask is a lightweight micro-framework designed for Python, with a simple and easy-to-use core that allows you to develop your own web applications. In addition, the Flask core is also extensible. Therefore, Flask supports an on-demand extension of different functions to meet your personalized needs during web application development. This is to say, with a library of various plug-ins in Flask, you can develop powerful websites. Flask has the following characteristics: Flask is a microframework that does not rely on other specific tools or components of third-party libraries to provide shared functionalities. Flask does not have a database abstraction layer and does not require form validation. However, Flask is highly extensible and supports adding application functionality in a way similar to implementations within Flask itself. Relevant extensions include object-relational mappers, form validation, upload processing, open authentication technologies, and some common tools designed for web frameworks. Flask is a web application framework based on WSGI (Web Server Gateway Interface). WSGI is a simple interface connecting a web server with a web application or framework defined for the Python language. Flask includes two core function libraries, Werkzeug and Jinja2. Werkzeug is a WSGI toolkit that implements request, response objects, and practical functions, which allows you to build web frameworks on top of it. Jinja2 is a popular full-featured templating engine for Python. It has full support for Unicode, with an optional but widely-adopted integrated sandbox execution environment. FastAPI FastAPI is a modern Python web application framework that has the same level of high performance as Go and NodeJS. The core of FastAPI is based on Starlette and Pydantic. Starlette is a lightweight ASGI (Asynchronous Server Gateway Interface) framework toolkit for building high-performance Asyncio services. Pydantic is a library that defines data validation, serialization, and documentation based on Python-type hints. FastAPI has the following characteristics:
