Service mesh vs. Kubernetes Ingress — what is the difference?

Service mesh and Ingress are two solutions used in the area of ​​application networking in Kubernetes. In this article you will see what characterizes each of them and understand where the real difference between them is. A service mesh is a kind of special “system” for communication between applications, different components of an application based on microservices architecture, or between various other workloads running in virtual environments, such as Kubernetes. The solution provides a rich set of features in the fields of traffic management, reliability, resilience, security, and observability.

What is and what is not accessibility design?

While building a new software product, development and UX teams usually focus on its functionality and usability. But do you know if your product is accessible? Why does it even matter? What is the difference between usability and accessibility? Read on to find out what accessible design is, what it isn’t, and how to make it work for your product. In terms of UX and UI, accessibility design is extremely important. The designer should always keep in mind that users might encounter the app or website in many different ways.

Outsourcing software development in 2022: pros and cons

Outsourcing is a business strategy that can increase efficiency, gain competitive advantage, and help achieve market goals faster. No surprise it is becoming an increasingly popular approach and more and more software-based businesses are deciding to outsource some or all of their development to external companies. It is estimated that the demand-supply gap for software developers will grow by 22% between 2020 and 2030, making it more difficult for companies to recruit skilled programmers and build in-house teams.

What is a service mesh — everything you need to know

A service mesh is an increasingly popular solution in the area of ​​application networking, in Kubernetes and other environments. If you are still not familiar with the concept, in this article you will find everything you need to know before taking a deeper dive. Over the past few years, we have seen a shift away from approaches based on monolithic code when designing software applications. Instead, modern design is based on microservices architecture. At the end of the day, it is about delivering basically the same business logic, not in the form of a large monolith but as a collection of loosely coupled and independently deployable services.

Is Network Service Mesh a service mesh?

Service mesh solutions are increasingly becoming an important element of modern applications built on the basis of microservices architecture. But here and there, you can also hear about a project called Network Service Mesh. Is it another variation on the service mesh theme or something completely different? A service mesh is a kind of “network” that connects all microservices within a given application. In fact, it is extra software that acts as an intermediary layer between services and provides a wide range of functions in the fields of security, observability, and traffic management, as well as reliability and resilience.

Security standards at CodiLime — how do we keep the data safe?

According to SonicWall's 2022 Cyber Threat Report, the number of cyberattacks - including encrypted threats, ransomware, intrusion attempts, and cryptojacking - rose by more than 100% during the past year. Cyberattacks equal lost money. And in today's business environment, nobody can afford that. Here, we share with you how we mitigate these risks at CodiLime and, along the way, save money - ours and our clients’. At CodiLime, we are security freaks - our auditors praise us for the fact that our procedures are an organic part of the organization’s ways of working.

Learning Go for C++ developers — differences and insights

Some people enjoy discovering new songs, bands and genres. Others prefer listening to the songs they already know. One could say the same about programming languages. I've been listening most often to the song of C++, which I just enjoyed building my expertise in. Also Python was a recurring beat. Recently, having started a new project, I've been asked to learn the song of Go. This post is not supposed to be any kind of introduction to Go’s learning path. I just wanted to share some of my "Aha!" moments and analogies from the ongoing process of learning Go, from the perspective of the C++ genre.

CI/CD tools in DevOps — which should you choose?

Automation is now a must in software development if a business wants to keep pace with dynamic market trends and customer needs. It helps with process optimization and makes the most of the budget. DevOps is an approach that allows businesses to achieve these goals as it implements a set of norms and practices. However, to make the final product really stand out, it is worth supporting the process with tools that facilitate DevOps engineers' work. CI/CD, or Continuous Integration (CI) and Continuous Delivery or Continuous Deployment (CD), is one of the core paradigms in software development that benefit both process and business, thanks to its focus on delivery and quality.

CSS Container Queries. Why so enthusiastic about those?

A front-end developer spends time adjusting CSS to the app they are working on, how much time depends on the specific project. Many people assume this is the easy part. I thought so too, but now I think I was wrong. CSS, or Cascading Style Sheets, is a style sheet language that focuses on the presentational part of the layout. Some people enjoy it, some even love it, but there are people who avoid it at any cost and try to focus, for example, on JavaScript logic instead. There are times that I feel like I belong to both groups.

Building an MVP: 6 common mistakes to avoid

Building a minimum viable product is a recommended way to avoid failure while developing a new digital product. It doesn’t matter if your company is a tech startup or a large-scale corporation, an MVP will help you validate your business idea early and adjust your strategy to the feedback you receive. Every day, thousands of new products, websites, and applications are brought to the market. Some of them finally make a breakthrough but most of them don’t get off the ground. An MVP, if done right, saves you time and resources by helping you make better-informed decisions and find early adopters for your product.

FD.io’s VPP’s mechanical sympathy – thread and memory management techniques explained

We've previously explained how VPP processes packets in vectors as opposed to processing each packet end to end. But how is this processing spread across CPU cores? How exactly is a vector of packets structured?
