Microservice API Patterns: A Language for API Design

Aggregated on: Wed Feb 16 2022 00:04:58 GMT+0000 (Coordinated Universal Time)

In the overall API lifecycle, it is important to first align APIs with business capabilities, turn this into a clear and business-aligned value proposition for the API, and to also produce some API stories that demonstrate how to use that new digital building block. Moving on from this value focus, the next step then is to take the API stories and turn them into high-level designs. The result of this are “API conversations” where it is shown how an API consumer interacts with the API. These conversations are not yet specified down to the level of which protocol to use and what the technical details of the exchanged messages look like, but they do show conversation patterns.

HTML is full of lots of different tags for text. These tags let us display text in our HTML documents in the ways we want it to be displayed. Although tags are a basic feature of HTML, there is a lot to learn about them. Most tags for text are inline but there are exceptions. When an element is inline, that means by default they have this line of CSS applied to them:

Aggregated on: Tue Feb 15 2022 23:34:58 GMT+0000 (Coordinated Universal Time)

Microsoft Outlook is a prominent email client used for sharing crucial information amongst organizations. This information passes over the internet and contains some confidential details. These details are subject to being hijacked by cybercriminals. Therefore, it is necessary to maintain the confidentiality of your email data. In this context, many users want the solution of how to send a secure email in Outlook. This article explains the two encryption methods that allow you to send a secure email in Outlook. Encrypting the email in Outlook converts the message into a scrambled ciphertext. Only the recipient having the private key can interpret the message for reading. Following are the two ways to encrypt email in Outlook.

Designing Cloud-Based Multimedia Solutions

Aggregated on: Tue Feb 15 2022 23:34:58 GMT+0000 (Coordinated Universal Time)

Private, public, or hybrid, cloud solutions for any business domain are designed to provide the freedom to grow and security for the organization and customer data. For cloud-based multimedia solutions, there is cloud-based custom transcoder IP that supports automated Video-On-Demand (VOD) pipelines. Cloud services offer solutions that ingest source videos, processes video for playback on a wide range of devices using cloud media converter, and store transcoded media files for on-demand delivery to end-users. Custom IP integration along with other cloud services showcases better feasibility of using Open-Source codec, to use one’s transcoder instead of cloud media-converter for multimedia solutions. In this blog, we will see how an Open-Source codec like AV1 is selected as a custom IP for encoding to integrate over the cloud as a service.

How to Create Browser-Specific CSS Code

Aggregated on: Tue Feb 15 2022 23:34:58 GMT+0000 (Coordinated Universal Time)

Every web page renders differently in different browsers. When a browser reads the code behind a website, it translates the information in the default settings. For instance, Safari and Internet Explorer have different default fonts, which means the font on a specific site changes when viewed in these browsers. Safari defaults to the Helvetica family and Microsoft’s Internet Explorer defaults to the Arial font family. This article discusses how to create browser-specific CSS code to ensure cross-browser compatibility for a website.

Data Fetching and Cache Maintenance With React-Query

Aggregated on: Tue Feb 15 2022 23:34:58 GMT+0000 (Coordinated Universal Time)

Fetching data from the server and maintaining it is a very crucial issue in frontend development. In this article, on behalf of Apiumhub, we will focus on the React.js library applications and how we maintain the server state with the library called React-Query. Into React-Query In React, there are three types of state: the local state, which is persisted in the React components; the global state, which all components can access; and the server state which is persisted in the server most of the time and depends on both sides. To manage the server state in the frontend and sync with the backend, we need to update, cache, or re-fetch the data efficiently. Sometimes we call the backend more than necessary, and this could cause performance problems in our applications. There, the React-query library helps us to solve these performance issues, manage the cache properly and give us useful features like query cancellation, stale time configuration, infinite query re-fetching, etc.

The Database Connection as a Leverage Point

Aggregated on: Tue Feb 15 2022 19:49:58 GMT+0000 (Coordinated Universal Time)

Most databases are accessed over a network connection. We tend to think of these connections as an opaque tube between the database client and the database server: whatever happens in these tubes is mysterious, and there is nothing we can do about it. I'd like to show you how these connections can in fact be used to augment and improve your information systems. By routing these database connections through a smart database proxy, we can observe, control and potentially modify the requests and responses going back and forth. This gives us a powerful leverage point:

I recently picked up Ethereum development with Solidity, and while it's been fairly easy to write smart contract code, I've had some trouble putting all the pieces together to form a decentralized application (DApp). For example, I couldn't understand the role of wallets as a means of identification in Web3. I also didn't know how to simulate a staging environment similar to what we have in Web2 where I could thoroughly test out my DApp before deploying to the Mainnet, since smart contracts are "Immutable" and cannot be updated once deployed.

Cassandra Database Migration to Kubernetes with Zero Downtime

Aggregated on: Tue Feb 15 2022 16:34:58 GMT+0000 (Coordinated Universal Time)

K8ssandra is a cloud-native distribution of the Apache Cassandra® database that runs on Kubernetes, with a suite of tools to ease and automate operational tasks. In this post, we’ll walk you through a database migration from a Cassandra cluster running in AWS EC2 to a K8ssandra cluster running in Kubernetes on AWS EKS, with zero downtime. As an Apache Cassandra user, your expectation should be that migrating to K8ssandra would happen without downtime. To make that happen with “classic” clusters running on virtual machines or bare metal instances, you will use the datacenter (DC) switch technique which is commonly used in the Cassandra community to transfer clusters to different hardware or environments. The good news is that it’s not very different for clusters running in Kubernetes as most Container Network Interfaces (CNI) will provide routable pod IPs.

EDI vs API in B2B Partner Onboarding| How To Use Both Methods

Aggregated on: Tue Feb 15 2022 16:34:58 GMT+0000 (Coordinated Universal Time)

Introduction This discussion has been going on for years: who wins the battle of EDI vs API? On the one hand, EDI is considered to be a legacy technology that is difficult to implement and maintain. Yet at the same time, many enterprise-grade software systems have it as a key element of information communication. In fact, EDI continues to play an integral role specifically in the supply chain-oriented industries such as logistics, automotive, and, of course, retail. On the other hand, more modern software systems and web services rely on API connections. APIs are usually much more cost-effective compared to EDI solutions. In addition to that, they make a strong case for helping businesses meet the demands of the omnichannel age as well as be able to react quickly to the changing needs of the market. While some supply chain processes are less time-sensitive, for others such as quotes comparison or shipments management timely reaction is of the essence, and the event-based, synchronous communication enabled by API can do just that.

Both containers and microservices are gaining immense popularity and becoming industrial norms for enterprise organizations. According to a study conducted by Statista, 19% of respondents said that containerization is already playing a strategic role for their business. Whereas, according to a survey on microservices adoption, 92% of respondents say that they had some success with microservices. But what exactly do we mean by microservices and containers? Let’s find out! In the IT industry, a microservice architecture means breaking down software into chunks of loosely coupled services. Lately, organizations are relying heavily on microservices for their DevOps needs. According to research conducted by market analysis, the synergy between microservices and DevOps will grow globally at a CAGR of 16% by 2022.

Microservice Design Patterns

Aggregated on: Tue Feb 15 2022 12:49:58 GMT+0000 (Coordinated Universal Time)

Microservices have an entirely new set of problems due to their distributed service-oriented architecture. As a result, microservice design patterns have surfaced. This post will consider the specific design patterns that can help us build reliable, secure, and traceable microservices. Monitoring is fairly simple for a monolithic application. A few log statements here and there, and you can generally follow the life of a single request. However, when you have distributed applications, you are responsible for tracing many requests through many microservices, each potentially with its own identifiers and logging methodologies. So, we need a design pattern and some tools to help us trace the life of a request, from the cradle to the grave.

Contextual Polymorphism With Operator Overloading in Kotlin and Scala

Aggregated on: Tue Feb 15 2022 12:49:58 GMT+0000 (Coordinated Universal Time)

Polymorphism is one of the key concepts in programming languages. There are several kinds of polymorphisms such as ad-hoc polymorphism, parametric polymorphism, subtyping polymorphism, and a few others. In this article, we will mainly focus on ad-hoc polymorphism which relies on function overloading or operator overloading. This article is about ad-hoc polymorphism that you’ve learned from your object-oriented Programming class, yet you will see it from a different angle, and you may be amazed at how elegant it is. The concept remains the same, only the presentation that is different. In the end, I’d like to take you to another concept that extends polymorphism further where the object can morph to a different kind depending on the context.

More Than 10 Free Custom CSS Checkboxes

Aggregated on: Tue Feb 15 2022 12:04:58 GMT+0000 (Coordinated Universal Time)

Over the last few days, I've been working on creating some creative checkboxes that use pseudo-elements, SVG animations, and a few other techniques. For some, I used a little bit of Javascript to allow for more options. A big annoyance for me is the fact that checkboxes return a value of on and off, so for these, I've created a hidden input that returns a value of 1, 0, or a number in between for some of the checkboxes which have multiple options. That means you can access the checkbox value directly from this hidden input with class .hidden-value.

Your system is putting your business at risk and you haven’t fixed it. Don’t touch what isn’t broken, right? Well, while that may be currently working for you, you are walking down a slippery slope. Legacy systems for long-term business operations come with many risks, and it may be time for a change. We will discuss ways to move on from legacy systems to put your business in a better position. Define Your Legacy System There is no standard or generally accepted definition of a legacy system. When talking about legacy systems, age is not the first point of consideration. While this may be a factor, it is not always the case because newer systems and software can be classified as legacy systems.

DevOps - Overcoming the Struggle

Aggregated on: Tue Feb 15 2022 10:04:58 GMT+0000 (Coordinated Universal Time)

Everyone is ‘doing’ DevOps, but only a handful of people are getting the business value they expect. Why? The reason is very simple, those who are getting the business value know exactly what to focus on in getting the DevOps model right in the organization. They also know that business value is the ultimate goal of DevOps, and value begins and ends with the customer. There are 4 key elements to get DevOps right in an organization. They are not only simple but the most ignored aspect. DevOps would be highly effective in bringing the business value to the customers if and only when these things are followed effectively. Here are the 4 key DevOps components: 1. Leadership 2. Organization structure 3. Value stream mapping (VSM) in DevOps 4. Pulse-Check Leadership Leadership – the most uttered word in all organizations and industries today. My greatest inspiration for leadership comes from the leadership guru “John C Maxwell” and John says, “Everything raises and falls on leadership”. DevOps is no exception to it and in DevOps world, “Leadership” is the most overstated but under practiced phenomena today. “People buy-into the leaders before they buy-into their vision” – John Maxwell Before people in the organization follow any worthy vision or causes, they are keen to follow “worthy leaders” first. People in the organization do not buy into DevOps vision just because it is worth doing it or it is the “in-thing” to do it, until they buy-into the leaders first. So, the primary reason for DevOps success or failure in an organization is totally dependent on the leaders of the organization. Characteristics of DevOps Leader Here are some key characteristics every DevOps leader must focus on to have: Influencing According to John Maxwell, “Leadership is influence, Nothing more nothing less”. DevOps leader must have the influencing skills to be effective in the organization. People Focused Rather than Privilege Focused No-one becomes leader automatically by the privilege or the title they have. Leaders need to be people centric and value them all the time. People don't care how much you know until they know how much you care. Creating DevOps Culture DevOps is a culture and the whole organization needs to be doing DevOps for it to be successful. Without the right mindset and culture, it’s hard to realize the full benefit of DevOps. It is the responsibility of the leader to create the right culture. Patience A greatest virtue, a leader can possess. DevOps transformation do pose lots of uncertainty and leaders true characters are seen based on how they can handle the tough times and showcasing patience. See Beyond Possibilities Leaders don’t just cast vision, but they are visionaries themselves. Leaders not only see things before anyone sees it, but they also see more than others see it Organization Structure An advantage of the functional structure is that grouping jobs by skills and knowledge and clear roles and responsibilities. However, the disadvantage is that each functional departments may become too siloed, often losing sight of the organization as a whole. Why This Siloed Structure Wouldn’t Work for DevOps DevOps is owned by just 1 division head in the organization, and he/she would need to sell or justify this service to the rest of the organization. There is always seller-buyer dynamics between DevOps division head & other division heads. Not all the division heads are having the same level of KPIs to rollout DevOps. Unfortunately, It’s the direct responsibility of this 1 person to promote DevOps for the entire organization. No synergy between DevOps teams and the rest of the organization as they are mostly operated in Silos. Other enabler teams like Infrastructure, operations, tooling are not always together with DevOps teams in this structure. Most of all, business don’t see the value in DevOps and they are always seen as additional overheads/cost in this type of organization structure. Recommendations Like any other scrum team, DevOps team should be a permeant scrum team in the organization. it is important to create a cross functional team for DevOps. Appoint a product owner for DevOps. This person should have direct access to the organization leaders to influence the roadmap for DevOps. DevOps scrum team should be the combination of DevOps, engineering, tooling, architecture, infrastructure, operations and required business representation always. This cross functional setup should be replicable & increased to more number of scrum teams as the demand increases. Topmost leadership in the organization should own up driving DevOps. As DevOps requires Cultural shift in the organization, it should be driven top-down. DevOps success should be the KPI of CIO in the organization. VSM in DevOps Seeing is Believing - Value streams are a visual tool that enables organizations to objectively measure and track what is most important to the organization and what they believe will actually bring value to customers. Measuring End-to-End Flow Flow Metrics measure the flow of business value through all the activities involved in the process. It clearly represents the bottleneck in a end-to-end value stream and helps to determine the area to focus and improve. When we measure a subset of the flow, such as the time it takes for developers to complete an “user story” or the time it takes to deploy the changes to production, we can optimize that segment of the value stream

This year is no different with 80% of organizations in the mid-level of maturity. Interestingly, this time the report breaks down this midsection into three sub-categories: low-mid, true-mid, and high-mid.

Enter the Cloud Native Dojo: Blackbelt-Level Debugging

Aggregated on: Mon Feb 14 2022 16:34:58 GMT+0000 (Coordinated Universal Time)

Debugging is often viewed as an art form or a craft. This is true for most engineering-related troubleshooting processes (e.g., the art of motorcycle maintenance). We’re usually indoctrinated into the basic moves by a senior developer and are then thrown into the proverbial pool. As a result, even senior engineers sometimes have gaps in their debugging skills. There are very few university courses or books on the subject, so it’s really hard to blame them. In his book, “Why Programs Fail — A Guide to Systemic Debugging”, Andreas Zeller told a story from his youth working at a computer store. A customer walked into the store with a new Commodore 64 computer. For context: The computers back then booted directly to a basic interpreter; basic would accept line numbers as the first argument. He tried inputting this valid basic line:

Yet, every cloud has a silver lining. In my case, I learned about System.Logger. In short, System.Logger is a façade over your logging engine. Instead of using, say, SFL4J's API and the wanted implementation, you'd use System.Logger instead of SLF4J. It's available since Java 9, and it's a bummer that I learned about it only recently.

Tech managers often focus on immediate achievements instead of real impact. They are proud when employees work late and believe it equals productivity. In reality, this approach is counterproductive. Sustainable software development yields much better results. It’s a comprehensive approach to optimizing the SDLC, finances, and human resources during software engineering and use. Sustainable software also means minimum harm to the environment, which is critical given that by 2040, ICT will account for 14% of the global carbon footprint.

It is now an integral part of modern web development and helps in creating rich, user-friendly websites.

Continuous Feedback Is Key To Taking Your AI From “Good to Great”

Aggregated on: Sun Feb 13 2022 22:19:57 GMT+0000 (Coordinated Universal Time)

Deploying AI instantly brought value and growth to many businesses. However, it is well established that sustaining the value over time, not to mention maximizing it, could be quite challenging. Continuous optimization is the key to successful AI deployments. Begin with a product that’s good enough, learn from how it performs in the real world (especially as the data environment changes), and then improve; then learn and improve again, and so on. It’s a bit of an obvious insight, but it is rare for AI-driven products to be perfect from day one. To accomplish continuous optimization you need continuous feedback. You need “eyes and ears” observing your data and models and telling you whether they’re performing well. That’s easier said than done, for various reasons. These reasons are outlined below.

Meet Josh (a pseudonym). Josh is your typical developer. He’s good at writing code in his native language, hates documentation, and REALLY hates the “drag and drop” approach to developing software found in bloated API management platforms. Josh would rather write code, weave in some docs and avoid worrying about security, networking, deployment, and reliability. Josh avoids venturing into newer networking technologies like Istio, labeling them unnecessarily complicated to configure and maintain. He would rather write everything in Java, Groovy, or his go-to integration library: Apache Camel. Recently Josh stumbled across an open-source API platform called Kong. After 30 minutes of playing around, Josh discovered how easy it was to:

The AWS Cloud Development Kit (CDK) allows you to define your AWS resources using the programming languages you know and love. This concept piqued the interest of many of us here at Instil; when someone offers us the ability to use Typescript instead of YAML we’re sold! I have been using CDK for the past 3 years for container-based and serverless projects, and what I think is CDK’s greatest strength are the guard rails it provides to the developer:
