When it comes to building Docker containers, you should always strive for smaller images. Images that share layers and are smaller in size are quicker to transfer and deploy.
But how do you keep the size under control when every
RUN statement creates a new layer, and you need intermediate artefacts before the image is ready?

When you deploy an application in Kubernetes, your code ends up running on one or more worker nodes. A node may be a physical machine or VM such as AWS EC2 or Google Compute Engine and having several of them means you can run and scale your application across instances efficiently. When there is an incoming request, the cluster routes the traffic to one of the nodes using a network proxy. But what happens when network proxy crashes? Does the cluster still work? Can Kubernetes recover from the failure?

When you design and build applications at scale, you deal with two significant challenges: scalability and robustness. You should design your service so that even if it is subject to intermittent heavy loads, it continues to operate reliably. But how do you build such applications? And how do you deploy an application that scales dynamically? Kubernetes has a feature called autoscaler where instances of your applications are increased or decreased automatically based on metrics that you define.

In the last few years, the industry has experienced a shift towards developing smaller and more focused applications. Smaller services are excellent from a product and development perspective: they are quicker to deploy, easier to iterate on and can handle failure gracefully. But how does that cultural shift impact the infrastructure? The current practices don't fit the paradigm well, and you might end up paying the extra price in your cloud bill at the end of the month.

Spot Instances are unused servers that are available for less than the regular price. Therefore, you can significantly save on your infrastructure costs. It does come with a price, though. Your cloud provider can take away your spot instance at any time, and give to another client who has requested it at a standard cost. How can you save money, but work around disappearing servers? Learn how you can leverage Kubernetes to self-heal your infrastructure and cut costs with Spot Instances.

Solar panels are getting cheaper, and are becoming an economically viable source of renewable energy in many parts of the world. For solar panels to operate efficiently, they need to be kept clean and pointed at an optimal angle to the sun that balances power generation and prevents overheating. An embedded computer is in charge of monitoring metrics and driving the actuators. But when you have thousands of solar panels and embedded computers how do you orchestrate software updates, monitor uptime and secure communications?
