In order to achieve rapid delivery with higher quality, the developer and QA start to adopt some automation technologies.
#WHAT IS KUBERNETES IN DEVOPS SOFTWARE#
Continuous IntegrationĪs discussed previously, the surrounding software delivery environment keeps changing however, the delivery cycle is getting shorter and shorter. Therefore, software and service delivery cycle takes between a few days to a few weeks. Now, infrastructure is one of the important components and being within a scope of Software Development Delivery Cycle, because the application is installed and runs on the server side, rather than a client PC. Now, cloud services such as Amazon Web Services ( AWS) and Google Cloud Platform ( GCP) can be easy to create and manage dynamic infrastructures. Virtualization technology and Software Defined Network ( SDN ) make the server machine dynamic. On the other hand, infrastructure becomes dynamic, since the application requirement keeps changing and the capacity needs to grow as well. The web browser is the interface of the application software, which need not be installed anymore. Software delivery on the cloudĪ few years later, smartphones (such as iPhone) and wireless technology (such as Wi-Fi and 4G network) became widely accepted, and software application also changed from binary to the online service. Therefore, SDLC doesn't tend to include these infrastructures in the scope yet. On the other hand, the infrastructure (such as server and network) is very static and set up beforehand. This model makes the SDLC cycle and the software delivery faster and also easy to be adjust during the process, because the cycle is from a few weeks to a few months which is small enough to make a quick adjustment.Īlthough this model is currently favoured by the majority, at that moment, application software delivery meant software binary, such as EXE program which is designed to be installed and run on the customer's PC. When the desired modules or functions are ready, it will be released as shown in the following diagram: Then, it delivers to the QA, and then the developer continues to add a new module and finally delivers it to the QA again. In this case, the software developer writes only a small logic or module, instead of the entire application in one shot.

Microsoft Windows update was also introduced since Windows 98.
#WHAT IS KUBERNETES IN DEVOPS PATCH#
Even if new bugs are found, it is now easier to update and deliver to the customer as a patch by electrical delivery. Many developers started to adopt new methodologies such as incremental, iterative, or agile models and then deliver to the customer faster.
#WHAT IS KUBERNETES IN DEVOPS HOW TO#
Therefore, many software companies (also known as dot-com companies) tried to figure out how to shorten the SDLC process in order to deliver the software that can beat the competitors. Agile and electrical deliveryĪ few years later, the internet became widely accepted, and then software delivery method also changed from physical to electrical, such as online download. Waterfall model and physical delivery used to take a year to several years. It perfectly matches the physical software delivery because it needs to coordinate with logistics management that press and deliver the floppy/CD-ROM to the user. The project tends to proceed and complete to release, then it goes to the next release cycle including a new design. This is because it will impact the overall schedule and cost. For example, after starting or finishing the Implementation phase, it is not acceptable to go back to the Design phase (to find a technical expandability issue, for example). In this case, we can't go back to the previous phase. At the end of the book, other orchestration frameworks, such as Docker Swarm mode, Amazon ECS, and Apache Mesos will be discussed. The final stage of the book will cover deploying and managing your container clusters on the popular public cloud Amazon Web Services and Google Cloud Platform.
It will proceed to introduce permission control for Kubernetes resources via attribute-based access control and role-based access control. We then move on to advanced DevOps skills such as monitoring, logging, and continuous deployment in Kubernetes.
The book will then introduce networks in Kubernetes. It will move on to how to containerize applications and deploy them into. The initial stages of the book will introduce the fundamental DevOps and the concept of containers. This book will guide you from simply deploying a container to administrate a Kubernetes cluster, and then you will learn how to do monitoring, logging, and continuous deployment in DevOps. Kubernetes is an orchestrator that creates and manages your containers on clusters of servers. Google developed Kubernetes, which orchestrates containers efficiently and is considered the frontrunner in container orchestration. Containerization is said to be the best way to implement DevOps.
