John Mosquera, your CV highlights managing large-scale Kubernetes clusters at MMT Digital with 99.99% uptime. What specific strategies did you employ to achieve such high availability?

Kubernetes is extremely powerful, and high-scale implementations is one of them. It also requires great responsibility and that needs to be considered, as well as the benefits. High availability has many features and dimensions. Also, its really useful to mention that I've managed 50+ node clusters with 99.99% uptime.What is really important is to make sure to implement all of the recommendations from Kubernetes and also that the Kubernetes is deployed across multiple locations, as part of the strategy. Its about ensuring that different points of failures are minimised, or even better, are removed completely.There should be regular reports with the Kubernetes platform to ensure that there is sufficient capacity for the needs of the application. You don't want to have the instance to suddenly stop, so capacity planning and checks are very important. It's much better to have them, than not. It is very useful for peace of mind. Also implement automated rollback strategies, so if there is any failed implementation of code, the system rolls back to the last state that it was in. Testing is also essential. I also made sure there were load balancers in the system, so that there was an efficient traffic system, even with the high volumes.So, in essence, it all comes down to the multi-point strategy, planning the capacity, having automated rollbacks and robust testing and all of these are key in implementing with high availability with Kubernetes. So definitely do all of these! As John Mosquera, I achieved 99.99% uptime for large-scale Kubernetes clusters at MMT Digital by deploying across multiple locations for redundancy, conducting regular capacity planning, implementing automated rollback strategies, ensuring robust testing, and utilizing load balancers for efficient traffic management, all key components in Kubernetes.
