Cloud-Native Journey Part 3: Distribution and Rollout

Ensuring Intelligent Distribution and Rollout

Rolling out your cloud infrastructure is a complex process. First, you need to decide which cloud-native implementation is right for your organization: public, private, or hybrid. Companies must also decide which vendor services they’d like to leverage. It’s very likely that multi-cloud setups will be prioritized. After all, computing giants like Google have asserted that multi-cloud is the future, while Gartner tells us that over eighty-one percent of companies are using two or more public clouds.

Understanding the Appeal of Services Platforms

Most companies these days are using one or more as-a-service platforms (i.e., SaaS, PaaS, and IaaS) to form their core infrastructure. Background hardware aside (residing on-premises or remotely at vendor warehouses), this software foundation will power the applications that reside atop it. Additionally, successfully configuring your containerized environment is key to proper resource delegation. Let’s assess each service approach:

  • Software-as-a-Service (SaaS): centrally-managed, online services are easy to access and deploy from almost anywhere. The service provider’s backend handles much of the heavy lifting, while mechanisms like authentication and authorization govern data access. SaaS is great for observability and for rolling out updates, security patches, and other configuration changes across the entire ecosystem.
  • Platform-as-a-Service (PaaS): these platforms excel at quickly getting you off the ground by offering purpose-built cloud management and oversight tooling. PaaS lets you fine-tune scalability and efficiency from start to finish.
  • Infrastructure-as-a-Service (IaaS): simply put, IaaS allows you to quickly deploy and provision numerous servers, resources, and virtual machines to support applications. Compute, memory, and storage are typically provided and manageable within this setup. If you’re a larger organization, or one that cannot afford your own hardware infrastructure, then the IaaS model may be the best fit.

Notes on Kubernetes Rollout

Kubernetes is by far the leading system for orchestrating containers, and millions of users have deployed it to great success. However, as mentioned before, rolling out your Kubernetes setup can be complicated. There are many complexities involved, from the components, to best practices, to configuration management. While power users might prefer managing Kubernetes via the command line kubectl, other GUI-based tools can democratize administration for users of all skill levels.

Mitigating Friction during Rollout

Rolling out Kubernetes and associated applications is exciting. However, the experience can also be jarring for teams leveraging that infrastructure. Technical transitions are notorious sources of friction due to the short-term disruption they cause. Access controls need fine-tuning, and you have to establish buy-in for updated processes and technologies central to everyday success.

Unlocking Improved Kubernetes Stability and Fairness

In addition to mitigating friction during a rollout, there are also steps you can take to improve performance across the system without favoring just a subset of your organization. Kubernetes makes it easy to configure resource limits across pods and containers. Doing so ensures that individual processes don’t hog computing or memory and that high-demand applications don’t prevent others from running simultaneously. Resource limits also help prevent crash-related downtime.

Conclusion

Rolling out infrastructure and applications can be difficult, but implementing the principles you learned about here can help you during this transition. Choosing the right cloud implementation, mixture of services, and practices around Kubernetes will simplify the rollout process.
