In today’s highly competitive business sector pace and user experience decide who wins or who fails.
Robust and complex monolithic solutions are things of the past, while a more agile, and modern approach is available for those organizations that want to stay on top.
Microservices are getting more and more traction, as they are helping enterprises adapt to the rapidly changing business environment with their granularity and flexibility. When using microservices, organizations can break a system down into smaller parts so that they are easier to scale, more cost-effective, reusable, and not language specific.
Many enterprises are aiming for the benefits of 100% Cloud Native applications, though they might be overwhelmed by the magnitude of starting a project like this. What is Cloud Native exactly? Which technologies companies need to execute this? What are the best practices? This is what we are going to explore in this article to make the transition process easier for your company.
Before deep diving into the required technological background of executing microservices, let’s take a step back and explore what Cloud Native really is and understand the whole concept.
Cloud Native is basically an umbrella term for the online-first approach that encompasses containers, service meshes, microservices, immutable infrastructure, and declarative APIs. This approach is used by many of the world’s biggest organizations, like Walmart, Verizon, JP Morgan Chase, or Visa.
Now that you know what you should aim for, and why, let’s jump into the details of the technologies you will need to use in order to create a flawlessly operating Cloud Native system.
.NET Core is a general-purpose and versatile framework that can be used to build a multitude of software, such as web-, mobile-, or desktop applications, microservices, or even IoT solutions. It is not limited to a single programming language, which is one of its biggest advantages over other frameworks.
Apart from it being language-independent and supporting a variety of application types, it has other advantages that make .NET Core ideal for building a Cloud Native application.
Docker is a technological solution that enables developers to package up an application with all of its libraries, configuration files, and its dependencies and deploy it as one package, called a container. Docker uses operating system virtualization to make this containerization process happen, instead of running the program on virtual machines, which makes each package easy to distribute and manage.
Docker is used by global organizations like Spotify, PayPal or ING. In 2020, the enterprise counts a total of 130 billion pulls on the Docker Hub, and a total of 5 million Hub users. Moreover, 451 Research estimates the overall value of the application containerization market to reach $3.4 billion in 2021.
This growing attention is justified by the significant positive impact this technology has on development processes and the production environment, as using Docker reduces costs and saves time for the developer team.
Cutting costs is one of the most important advantages. Docker helps organizations reduce the number of used servers and the costs and resources needed to maintain them. This eventually results in a higher Return on Investment (ROI) that is valued by all enterprises.
Standardizing the infrastructure is key to increase the productivity of all people working across the company. Docker not only helps the developer team to find, analyze, and fix bugs but also enables them to focus on other crucial projects, like customer-, or in-house feature requests.
Portability across different types of environments and platforms is one of the most pressing reasons why organizations choose containerization. As Docker containers are able to run on a range of infrastructures, starting from virtual machines, data centers, through on-premise solutions to public cloud, it makes development and deployment a lot faster and easier. Moreover, Docker containers can function on most cloud instances, if the host operating system supports Docker, while consistently providing similar functionality.
Continuous development and testing are smoother with Docker. This technology has been developed to handle configurations and dependencies internally, meaning that programmers can use these containers starting from the development process until the end of production. If fixes or code upgrades are required, developers can test their code, then deploy them on all existing containers swifter and easier than before.
Even though the characteristics of .NET Core make it an ideal fit for containerization, such as flexibility, modularity, and its lightweight nature, there are some use cases when it is better to use the .NET Framework instead of .NET Core.
Kubernetes is an open-source container-orchestration solution, which has been designed with the purpose of automating app deployment, scaling, and management, which ultimately enables developers to create applications faster without any loss in code quality. Kubernetes is most of the time used to develop and maintain microservice-based architectures coupled with Docker because they form a complete ecosystem with their feature sets addressing the most common concerns around Cloud Native applications.
Sumo Logic’s Continuous Intelligence Report shows AWS customers’ growing rate of adopting Kubernetes, which has increased by 6% only in a year that demonstrates how swiftly this solution is getting traction around the world.
What is more, according to the 2019 research of RightScale, Azure adoption has now reached 85% of AWS adoption, up from 70 percent last year.
As user experience is getting more and more important in the online space, microservice-based applications became the most feasible means to comply with the high user- and in-house expectations. In order to create Cloud Native apps that fulfil these swiftly changing demands, IT teams need to use technologies that shorten development-, testing-, and deployment time, which at the same time, increase their efficiency, and cut costs for the organization.
Cloud Native apps developed with the help of .Net Core (or in some special cases .Net Framework), Docker, and Kubernetes are the modern technologies that enable enterprises to obtain these goals.
After reading the article, you have all the necessary pieces of information in your hands to scale your application to the next level. By choosing the above-mentioned solutions, your business can enjoy the advantages of all, which will not only result in the swift escalation of your solution’s quality and customer satisfaction but in the overall bottom line of your company.
In this article, I will show you a solution for zero-downtime deployment in Azure Kubernetes Service. To add a context for it, first, we are going through some Deployment strategies. Then, I will choose the one that fits our needs. Some of them are supported by Kubernetes natively, some are not (yet). Next, I will outline a System overview by showing you the necessary Kubernetes objects in our AKS. The following part of my article presents our Azure DevOps deployment pipeline to you and briefly goes through the scripts and other settings that do the main thing: zero-downtime deployment. Finally, I am going to Wrap up the things
IT outsourcing is very popular nowadays due to the fact that it has a lot of pros from a business perspective. There are a couple of blog posts written on this topic. You can take a look at one of them here. This post is about showing what makes an outsourcing partnership tempting for a developer – and at the end of the day, it is a win-win situation when both you and your developers are happy.
Gyakran tapasztaljuk, hogy a nagyvállalatok abban a tudatban élnek, hogy van belsős rendszerük, de mindez javarészt a különféle fájlmegosztó és -kezelő felületek vállalati használatában merül ki. A SharePoint alapú vagy Drive megoldások nagyon népszerűek, de ezek alapvetően dokumentumkezelő és projektmunka támogató rendszerek, így senki sem várhatja el tőlük, hogy valódi üzleti megoldásokkal szolgáljanak.
