Will the Kubernetes sidecar deliver container happiness?
IT teams tasked with managing containerization -- or that might be imagining a future full of containers -- may want to take a look at Kubernetes sidecar software. This proxy technology built into the service mesh architecture could prove useful in the ongoing battle to solve network management troubles.
Proponents tout the technology's ability to sort out the complicated network relationships that result from the use of containers and microservices. The Kubernetes sidecar technology found in service mesh technology first proved useful in giant online operations where conventional networking configurations weren't up to the task of managing microservices. But is there that same type of usefulness for organizations not named Twitter and Google? Does an IT shop that's not on the leading edge of DevOps need to look at Kubernetes sidecar software?
That's the question TechTarget's Beth Pariseau takes up in this edition of Modern Stack. She explores how the service mesh architecture works and how realistically its benefits might be applied to real-world IT scenarios. Some will see these advanced capabilities as unnecessary, at least for their current configurations. Others may be intrigued by the enhancements to security and greater control of traffic afforded by Kubernetes sidecar software in the mesh architecture.
If service mesh isn't in your near-term plans, it might be something to work toward, especially if your business intends to do more with containers and microservices in the years to come.
Also in this issue are features and columns delving into the practicality of the serverless approach; how developers influence an organization's decisions about cloud platforms; where containers, cloud computing and other emerging strategies affect application componentization practices; what no-code/low-code trends mean for the pace of application development; and how managing cloud spending can easily become a source of frustration even for those organizations that consider themselves especially prudent planners.
