Introduction To Kubernetes

With containerization gaining popularity over time and revolutionizing the process of building, shipping, and maintaining applications, it became the need of the hour to effectively manage these containers. Many tools were introduced to manage the lifecycle of these containers in large-scale systems. These tools were called container orchestration tools.

An orchestration tool takes care of provisioning and deployment, allocation of resources, load balancing, service discovery, high availability, and other important aspects of any system. By using container orchestration tools like Docker Swarm, Kubernetes, etc. we can easily describe the configurations such as volume mounts, env variables, image source, CPU, Memory configuration, etc., and use them as blueprints for creating containers.

Oops, We’re Multi-Cloud: A Hitchhiker’s Guide to Surviving

Over the last few years, enterprises have adopted multi-cloud strategies in an effort to increase flexibility and choice and reduce vendor lock-in. According to Flexera's 2020 State of the Cloud Report most companies embrace multi-cloud, with 93% of enterprises having a multi-cloud strategy. In a recent Gartner survey of public cloud users, 81% of respondents said they are working with two or more providers. Multi-cloud makes so many things more complicated that you need a damn good reason to justify this. At Humanitec, we see hundreds of ops and platform teams a year, and I am often surprised that there are several valid reasons to go multi-cloud. I also observe that those teams which succeed are those that take the remodeling of workflows and tooling setups seriously.

What Is Multi-Cloud Computing?

Put simply, multi-cloud means: an application or several parts of it are running on different cloud-providers. These may be public or private, but typically include at least one or more public providers. It may mean data storage or specific services are running on one cloud providers and others on another. Your entire setup can run on different cloud providers in parallel. This is distinct from hybrid cloud services where one component is running on-premise and other parts of your application are running in the cloud.
