Understanding Kubernetes to Build a Cloud-native Enterprise

As organizations continue to scale their digital transformations, there’s an urgent need to bolster the flexibility of their IT infrastructure to ensure innovation can happen from anywhere. To do this, many are turning to a relatively recent and very powerful addition to digital transformation strategies: Containerisation.
Containers are utilized to package up an application’s code and all of its dependencies to ensure the application runs reliably irrespective of its underlying environment. As such, the containerised application is essentially mobile and able to run nearly anywhere, including in a private or public cloud.
Ultimately, the use of containerisation allows for consistency across applications and further prevents error in the transfer of data and information. In fact, Gartner has reported that by 2026, 20% of all enterprise applications will run in containers — up from fewer than 10% in 2020.
However, it has not only become increasingly important, but now remains necessary to maintain the organization of containers. The more containers an organization uses, the more challenging it becomes to manage them.
Fortunately, Kubernetes, an open-source system for automating deployment, scaling, and management of containerized applications, helps solve this problem.
What is Kubernetes and Why is It Becoming So Popular?
Kubernetes was originally developed by Google as a tool to orchestrate containers and applications. But, over the past five years or so, it has expanded to become the default multi-cloud plane for orchestrating modern infrastructure. Kubernetes allows organizations to distribute workloads across multiple cloud providers efficiently.
Nearly a quarter (23%) of U.S. IT leaders surveyed by Wanclouds noted that their organization has implemented Kubernetes to modernize their IT environment. This statistic isn’t entirely surprising when you dig into the overwhelming benefits of Kubernetes, and how it helps cloud-native IT teams solve many challenges that are not only part and parcel of containerization, but digitization in general.
For example, there’s a need for high availability, scalability, and reliability in today’s fast-paced landscape. Moreover, not only are companies in dire need of cloud flexibility but their migration strategies need direction. Kubernetes helps IT teams standardize migrations, move legacy applications to the cloud, and ultimately increase their pace to market.
What’s the Price?
Despite Kubernetes’ draw, they can be costly.
Since most Kubernetes workloads are spread across public, private, and hybrid cloud infrastructures, securing these workloads is often a customized process, making them expensive, complex, and prone to misconfigurations. But the bigger issue impacting IT teams is cost visibility.
According to Wanclouds Cloud Cost and Optimization Outlook, 70% of U.S. IT leaders say their cloud costs have gone up since they implemented Kubernetes. A reason for this may be organizations’ increasing migration to multi-cloud environments, meaning they have to track costs across Kubernetes deployments across multiple clouds such as AWS, Google Cloud, Azure and IBM Cloud. Since these platforms don’t traditionally make it easy for IT teams to do this, it highlights the need for better cost visibility tools to help organizations optimize across hybrid and multi-cloud environments.
The good news is that Wanclouds’ new COaaS solution provides cloud-wide spend visibility and cost tracking for various resources across multiple accounts. This application enables customers to acquire real-time views into the cost of cloud resources, recommendations on infrastructure changes for optimization, purpose tagging, backups, and resource pause options: a one-click ability to stop and re-start idle resources and rightsizing recommendations for savings based on projected monthly costs.
Moreover, as multi-cloud spending becomes less efficient and increases annually for organizations due to stale and oversized infrastructure resources, our new solution lets you discover optimization opportunities such as backing up or removing Kubernetes clusters or test clusters.
Managing Kubernetes’ Security Threat
Kubernetes is known to have strict security protocols that help block access to components outside of a cluster. But it certainly isn’t unbreachable. Just a few years ago, hackers could hijack Tesla’s Kubernetes console to perform crypto mining and even access credentials to the company’s AWS environment.
Since then, the threat of cyberattackers has only increased. In fact, a survey conducted by Wanclouds last year of more than 100 AWS Community Builders, who are experts in cloud-native environments, found that the majority (55%) are most worried about malware or other cyberattacks causing the loss of company data.
This is highlighting the importance of setting up a cloud-native disaster recovery plan to cover their Kubernetes workloads. This is something Wanclouds provides through our Disaster Recovery as a Service solution, powered by our SaaS automation suite, VPC+. Not only do we now make backups immutable but we do so while monitoring Kubernetes deployments for attempted ransomware attacks thus improving the recovery point objective. This means IT teams can proactively detect their systems for any integrity violations, leading to improved response time, reduction of data loss, isolation of infected infrastructure, and the ability to restore the latest backup rapidly
As the use of Kubernetes has recently been seeing new heights, it is important to recognize the growing variations and contrasts between preexisting applications and what has been developed and applied today. Like Kubernetes, the newest innovations of cloud migration and maintenance are being created within the cloud-native modality. Furthemore, they're using microservices, containers, and a powerful DevOps orientation.
By stabilizing network traffic, Kubernetes has made it so organizations can excel in the current landscape without faults in their systems. Ultimately, Kubernetes provides you with service discovery and load balancing - two influential elements to the success of organizations utilizing cloud platforms.
