Managed Kubernetes vs DIY: Top 3 Considerations Before You Choose

As containerization continues to explode, the need for a container orchestration and management platform has exploded with it. Kubernetes has become that de facto leader for orchestration and management.

At Platform9, we have observed that, as our customers enter the Kubernetes space, their primary inclination is to start doing the implementation by themselves. They want to be “hands on” and figure out how they can solve the problems that arise by themselves.

Top 3 Implementation Considerations for DIY Kubernetes

Along the DIY path, after they run into a number of challenges, they reach out and discuss a Managed Kubernetes solution with Platform9. From our experience, here are three main factors that need to be considered before attempting a DIY Kubernetes implementation:

  1. Deployment Time: To put up a production grade, highly available cluster, it can take 3 to 5 weeks and consume considerable resource time…time that could be focused on doing other things. It can be difficult for large scale enterprises to deploy Kubernetes across a diverse infrastructure base when situated in various geographical locations and operating both on the public clouds and/or on-premise infrastructure environments.
    You need to configure a complex blend of components, services, plugins and add-ons to deliver a production ready deployment. There is a steep learning curve – often requiring specific developer expertise that may you may not have in-house – to figure out the nuances needed for your enterprise’s specific installation. This can be an expensive and time-consuming effort for your enterprise.
  2. Ongoing Monitoring: Once the deployment is up and running, how do you monitor it? What are the things you’re looking for? How do you even know what you are looking for? You can surf the Internet and see what other people have encountered in the Kubernetes space; this takes a lot of time and potentially requires numerous unique search queries to find the specific information you are seeking.Issues related to log collection, workload monitoring, SSL termination, certificate management, and network isolation are a few of the features that need regular oversight to successfully run enterprise-ready Kubernetes in a large-scale organization. Ongoing, around the clock supervision is key.
  3. Troubleshooting: Once monitoring is in place, typically the last thing people ask is “Great, I found a problem. How do I solve it”? There’s no guaranteed run book out there that says when you see problem A, do step B. Again, you have to spend a significant amount of time surfing the web for solutions. When a problem occurs, IT personnel need immediate notification; they will then be responsible for researching the cause and correcting it as soon as possible. This can be challenging and take a lot of IT personnel time…while they simultaneously balance the maintenance and running of critical applications.

It is also important to install the latest upgrades and bug fixes on a timely basis. Kubernetes and its open source elements continue to evolve at a fast pace. Additional problems can occur in the production environment if a patch or upgrade is missed.

Managed Kubernetes vs DIY

What are the real costs for DIY Kubernetes?

There are several critical elements that must be addressed in order to achieve, and sustain, production-ready HA clusters. Each of these steps has a real financial impact in terms of your staff’s labor time for both initial implementation and ongoing maintenance. An example is shown below.

Key Features for Establishing Production-Ready KubernetesInitial Costs (number of work months to implement)Recurring Costs (number of FTEs required)Comments
Provisioning30.75Standing up of clusters needs to be carried out using config mgmt tool like Puppet, Chef

Cluster stand up will need to be carried out for each supported environment
Monitoring30.25Monitoring capabilities for Kubernetes infrastructure needs to be built to check for downtime

Processes need to be put in so that output from monitoring activities can be understood and acted upon by support staff
Upgrading10.75Custom scripts have to be written for carrying out upgrades for production clusters without incurring downtime

Upgrade schedules need to be planned carefully to keep pace with Kubernetes versioning while ensuring roll out of security features appropriately
Security20.25Authentication and Authorization needs to be carried by integrating with identity management systems (e.g., Okta)

Role based access control needs to be implemented
HA and Healing20.25Both hardware systems and Kubernetes clusters need to be highly available

Faulty HW/ VMs need to be replaced without incurring downtime
Load Balancing30.25Application level load balancing needs to be established (one-time cost to implement)

Recurring costs for enhancement and maintenance will need to be taken into account
Heterogenous Environment Support40.25Integration with multiple infrastructure including Bare Metal, VMware/KVM and public clouds needs to be supported
Cost Summary1-Year Cost of DIY2-Year Cost of DIY3-Year Cost of DIY

Platform9 Removes Operational Complexity with PMK

Our customers tell us they choose Platform9 Managed Kubernetes (PMK) because we distill away much of the operational complexity:

  • Deployment times go from 3 to 5 weeks to a matter of hours
  • 24/7 monitoring and troubleshooting support is provided
  • Upgrades and fixes are handled across all enterprise infrastructure environments.

This allows their developers to focus on what they do best – building and running applications. Plus, it allows developers to focus on the ability to scale rather than keeping their eyes on a single individual cluster.

If you have already started down the do-it-yourself path with Kubernetes and are facing difficulties, Platform9 can help. We’ve assisted numerous customers in transitioning from a DIY implementation to a Platform9 Managed Kubernetes environment.

To get started with Platform9, you can deploy a free sandbox with Kubernetes installed. The sandbox includes a guided walkthrough for SaaS-managed Kubernetes, which allows you to get your environment up and running in just minutes. You can also contact us to schedule a free consultation or to register for a Platform9 15-day free trial.
