All containers share the same CPU, but they are nice to each other, and they split the times based on their shares. And that’s fine because the Pod can use more memory and CPU than what is defined in the requests. Of course, processes still have CPU and memory requirements. And if your Tetris board is a real server, you might end up scheduling unlimited processes. You might want to prevent a single rogue app from using all resources available and leaving only breadcrumbs to the rest of the cluster.

While Flask itself can be used to build REST APIs, Flask RESTful provides a few useful odds and ends to get you started that bit faster.
Crawling Data with Beautiful Soup
Ideally I would like to work in an environment where these two worlds come together. A couple of years ago I started to build a new skillset in programming and to develop a practical knowledge of data analytics. Fast forward 3 years I have worked as a web developer and as a Python back-end engineer. I am now looking for a challenging finance-related role in a data-driven environment where I will be able to leverage both my programming skills and my knowledge of finance and risk management. A few weeks ago, I was interested in trading and found that the majority of companies are offering their paid services to analyze the forex data. My objective was to implement some ML algorithms to predict the market.
Setup instruction before the course to save time at the beginning of the course. I’m happy to help you via email, phone or Skype, zoom.us etc. in case of any questions or issues. Analysis of the needs and my help to choose or python api design design a great course during a phone call with the sponsor, HR, team leader or/and course delegates. On top of that, we ask delegates on the very first day what their needs are, to make even better usage of the course time.
The main aim of this course is to provide a wide understanding of building Web Service REST APIs with features details
The -slim suffix tells Docker to use the ‘slimline’ version of this image. This removes some ‘clutter’ included in the ‘full’ Python 3.7.8 image. Practically, this helps keep your image size small, which can help you keep costs down and performance up when your API is in service. As you might expect, many ‘real-world’ web APIs are going to be at least a little more complicated than that.
- As you saw earlier, the tests directory contains your test code for your API.
- In other words, it contains commands to build a Docker image, which can then be run as an isolated container.
- We use the Anvil Uplink to connect a Jupyter Notebook to Anvil.
- At the end of this tutorial, you’ll be able to turn any website into an API without using any online service.
Notice how your application has 256MB of memory guaranteed, but it can grow up until 1GB of memory. Your application might require at least 256MB of memory, but you might want to be sure that it doesn’t consume more than 1GB of memory. The application can use more than 256MB, but Kubernetes guarantees a minimum of 256MB to the container. If you think that your app requires at least 256MB of memory to operate, this is the request value. There are two different types of resource configurations that can be set on each container of a pod.
Analyst, Python Developer
Keep in mind, though, that you’re going to put a lot of server load on the site you’re scraping, so maybe check to see if they have an API or some other way to get the data. Companies put a lot of effort to provide services, so it’s best to respect their business and request permission before using it in production. This book is ideal for aspiring software developers who have a basic-to-intermediate knowledge of Python programming and who want to develop web applications using Python. Knowledge of how web applications work will be beneficial but is not essential. You’ll take your first steps by building a simple API and learning how the frontend web interface can communicate with the backend.
- If you have suggestions for improvements to the advice in this post, do make sure to get in touch and let me know.
- If you can collect all of the metrics in a database, you could take the average, max and min of the CPU and memory and extrapolate requests and limits.

- But here we would brief you about the objective of the entire training.
Let’s imagine you have an application with a limit of 250Mi of memory. Imagine having three containers that have a CPU request set to 60 millicores, 20 millicores and 20 millicores.
You could extend the same techniques to your apps and set the right requests and limits even if you haven’t used them before. A mechanism to collect metrics and decide how to derive requests and limits for CPU and memory. Now that you have created the Pod with resource requests, let’s explore the memory and CPU used by a process.
