Attention! This article is not an engineering article and is intended for readers who are looking for Best Practices in HighLoad and Web Application Fault Tolerance. Most likely, if you are not interested in learning, this material will not be of interest to you.
Imagine a situation: you launched some online store with a promotion with discounts, you, like millions of other people, also decided to buy yourself a very important (or not very :-) ) device, you go to the site, and the server has crashed. "Sorry, there are too many of you!" - administrators write somewhere on social networks and promise to solve this situation ...
There may be a great many such examples, but you know that there are mechanisms that allow the system to work without failure, even if requests come at the speed of light. And if you donβt know, but really want to know, then you are in OTUS for a course , where an experienced specialist in this field will tell you how to proceed so that the server does not crash again.
What knowledge do you need to have to take this course:
- Proficiency in one of the server-side development languages: Python, PHP, Golang (preferred), NodeJS (as a last resort), Java (as a last resort)
- basic website development skills
- basic knowledge of JavaScript
- SQL skills (querying): MySQL is used in the learning process
- Linux skills
Passing an entrance test will help you understand if you have enough knowledge to study in this course.
During the course, the course instructor will discuss with the students both typical and non-trivial problems in the field of web application architecture, talk about the best solutions to these problems, and, of course, you will also have a lot of practice. Upon completion of the "High Load Architect" course, you will be able to provide fault tolerance for web applications even when servers fail, create easily scalable web applications, use templates correctly and work with tools created by Google, Yandex, Mail.Ru Group, Netflix, etc.
Have questions about the course program? No problem. , where you can find out all the details in real time, ask questions, as well as get valuable information about the skills and competencies that can be acquired at the end of the course.
Telegram recently crashed for the umpteenth time, and do you know why? Because the Telegram developers didn't take the OTUS High Load Architecture course! (This is a joke, of course, but it has become quite a popular meme).
Let us recall that OTUS is always attentive to its graduates and helps them in their further employment, so after completing the course, you, like all graduates, will have a chance to get an invitation to interviews in partner companies, and in order to chance to increase, OTUS experts will help you to correctly compose a resume, pointing out your strengths.
And also you:
- you will receive materials for all completed classes (video recordings of webinars, completed homework assignments, graduation project)
- you can write rational and well-structured code
- you will receive a course completion certificate
- you will acquire skills in working with algorithms and data structures that are necessary when implementing complex projects in large companies
So, if you are a web developer, web development team leader, architect or technical manager, then the High Load Architect course is for you. During the training, you will learn how to use solutions in your projects that can withstand hundreds of thousands (and even millions) of requests per second, you will be able to properly optimize the performance of servers, and you will begin to effectively use the tools that are already in projects. Also, the course will update and systematize knowledge in the field of HighLoad.
Perhaps that's all. See you at !
