Mohammed NaserThe cloud terminology omnibus brings you all of the valuable, informational content on cloud terms we have published over the years.
Cloud adoption is rising all over, with significant breakthroughs such as new developments happening all the time. Over the years, we have published much explanatory content on cloud-related terms. This omnibus and its ensuing parts aim to bring you all of those valuable, informational content together so that you can access it all from a one-stop solution. Each section is linked to a detailed blog where you can find more information about the said topic.
Without further ado, here we go.
What is a Public Cloud?
A public cloud provides you with on-demand infrastructure components such as compute, networking and in some cases, it also provides services that sit on top of these infrastructure components. The infrastructure is generally shared because you have a fully isolated virtual machine; however, it is collocated with other virtual machines belonging to other customers in that cloud.
What is a Private Cloud?
A private cloud is an infrastructure model that delivers cloud computing services entirely dedicated to a single organization. The single-tenant environment allows businesses to have all the advantages of a public cloud while having more secure and customizable cloud resources such as compute, storage and networking.
The public cloud is beneficial for starting, as you're only charged for what you use, making it easy to transition into a cloud solution. It also allows you to quickly scale without worrying about investing in hardware in advance as you only pay for what you use. In most other cases, if you needed a large number of servers quickly, you'd be stuck waiting for hardware vendors, shipping, etc., and you wouldn't have much of a use for it when you don't need it anymore.
What is Continuous Integration?
Continuous Integration is a helpful strategy that allows developers to share their code into a shared repository that connects all developers on the platform. It helps developers test the code before adding a new feature or function within a software application during the development cycle.
The best benefit of this process is cost optimization. It helps the developer identify the elements that are redundant with the old code of the application or are simply faulty. This way, the developer may save a lot of time on their plate before merging the code piece with the original code of the application.
What is Cloud Waste?
Cloud waste is when organizations or individuals acquire more cloud than they need, and the utilization rate of cloud services is lower than that of adopting new cloud features. The reasons for cloud waste can include both static and dynamic workloads. Without differentiating between the workloads, an enterprise will likely encounter wasteful strategies in running their cloud.
Cloud waste is significant in unused resources, and the expenditure on these resources goes unchecked. Monitoring usage is substantial for both small and large enterprises to cost-effectively carry out their day-to-day tasks.
What is Kubernetes?
Kubernetes (also known as K8s on public forums) is a powerful system that Google developed to manage containerized applications in a clustered environment. It is a cluster management tool for Docker containers. Kubernetes aids in scheduling and deploying many containers replicas onto a node cluster. Since it's an open-source model, Kubernetes can run almost anywhere, and all the major players in public cloud providers offer easy ways to utilize this technology.
What is Kubernetes Ingress?
The basics of Kubernetes Ingress is that it exposes HTTP and HTTPS routes from the outside of a cluster to services created inside the cluster. Ingress essentially works to implement rules to control traffic routes. Typically, ingress is set up to provide services to externally reachable URLs, load balance traffic, offer name-based virtual hosting and terminal, secure sockets layers, or transport layer security.
What is Kubernetes Operator?
A Kubernetes operator is an operator used as a method of building and driving an application on top of Kubernetes. You can easily use Kubernetes tools to help you solve the problem of a complex application. Ultimately, a Kubernetes operator works to help extend the types of applications that you can run on it, thus taking pressure off your IT team. The IT team writes the software to capture all operational considerations from a Kubernetes application. All configuration and any deployment upgrades are covered.
What is Kubernetes Volume?
Kubernetes volume is essentially a directory containing the data accessible to containers in a given Pod. These volumes provide a plug-in mechanism for the container orchestration platform to connect ephemeral containers with persistent data stores in other locations.
Kubernetes volumes persist until the Pod is deleted from the system. Once the pod is deleted, its volume automatically gets destroyed. An equivalent volume is also created if a Pod is replaced with an identical Pod instead of deletion. Regardless of the node the Pod runs on, the platform will mount the volumes to the pod, allowing containers to travel across infrastructure without losing access to the workload's necessary but externally hosted data.
