Magalix is about helping companies and developers find the right balance between performance and capacity inside their kubernetes clusters. So, we are big Kubernetes fans. We went through lots of pains and learning cycles to make Kubernetes work properly for our needs. Those experiences also helped us a lot to empathize with our customers. Building fully containerized and building fully elastic Kubernetes managed microservices is hard and still requires a lot of legwork.
Kubernetes at its core is a resources management and orchestration tool. It is ok to focus day-1 operations to explore and play around with its cool features to deploy, monitor and control your pods. However, you need to think of day-2 operations as well. You need to focus on questions like:
Every day, we developers are hustling to keep up with the ever-evolving complexities of cloud infrastructure – and one of the biggest disruptions is the introduction of AI into cloud infrastructure. AWS, for example, has rolled out a wide range of fully managed machine learning services, which may soon help developers optimize their infrastructure more intelligently than ever before.
Switching from traditional Vms to containerized applications can bring major upgrades in efficiency and reliability. But if you handle your containers incorrectly, you’ll be throwing all those benefits out the window – and frustrating your users in the process!
If your organization is still dealing with the provisioning headaches of traditional VM architecture, it’s probably time to make the switch to containers.
Although containers present many advantages over traditional VM architecture, they also come with a number of inherent risks – some of which are elevated beyond those of a conventional VM environment.
Containers have completely changed the web development game. Ever since the release of Docker in March 2013, the concept of running services inside containers has exploded in popularity. Every time we talk with a developer in any tech sector, the topic of containers is just about guaranteed to come up.
But while containers do offer some distinct advantages over traditional VMs – for example, the ability to isolate CPU and network bandwidth from the rest of the operating system – containerized apps don’t provide a one-stop fix for all your provisioning frustrations.
Containers are just a different way to run applications — but in the end, they need to serve your business’s goals.
On the first day at my previous job, my manager asked whether we were getting a good return on investment (ROI) from our cloud infrastructure. After just two days on the job, I could clearly see that we weren’t. Our VM’s CPUs were running at five percent on average, and memory was running below 40 percent.
Does the following conversation sound familiar?
CEO: Our AWS bill has gone to the roof. Why?
VP of engineering: We’re adding new customers! We need enough capacity to keep up with the demand.
CTO: But our average CPU and memory utilization are quite low. Why do we need more capacity if we’re not using all the infrastructure we already have?
VP of engineering: We get traffic spikes throughout the day. We need to be ready for them.
These days, many developers find it easier and quicker to write limited scope services. Cloud Functions like AWS Lambda, Azure Functions and Google Functions provide a new serverless paradigm that hides infrastructure. In short: no servers, no pain!
Containers have already become the new standard for modular and efficient microservice applications. Instead of running applications on a server, the new standard is to package and deploy software across many different environments, providing consistency that keeps developers and operators at peace.
