Start Learninga hands-on course, drawn from a real incident
You build an agent that reads the alert, finds the cause, proposes one exact fix and waits for two people to approve it. Then you measure how often it is right. The drawing on this page is a real run from 6 November 2026.
One payment, lifetime access. It rises to ₹7,777 or $177 once every part is released, and everything published later is included.
the drawing above, played back
Every line below is from the terminal of the run on 6 November 2026, and every number from its record of model calls. Press play to follow the agent from the alerts to the cause in 11 seconds. At the approval it stops and waits for two people, and here those people are you.
The replay loads as you reach it.
drawing 01 · why this agent
Hands-On AIOps on AWS is a self-paced, project-based course by Roni Das on systemdesign.academy: you build AI agents for DevOps incident response. You build an AI agent that reads an alert, investigates a Kubernetes system with read-only tools, finds the cause, proposes one exact fix and waits for a person to approve it, and then you measure how often it is right. It is for developers who already know Python and the command line. You build it on your laptop first, using OpenAI models, and then run it in production on AWS: EKS with one IAM role per agent, real AWS incidents and an audit trail.
Incident work teaches agents properly: the agent has real data to read, every step can be checked, and a wrong action has a real cost. So the design keeps the model away from any change. Follow the numbers in the drawing.

detail B · it is not solved
On ITBench-AA, published on 27 May 2026, no AI model scored above 50% precision at finding all the root causes across 59 injected Kubernetes faults. That is why this course measures the agent instead of trusting it.
detail C · the real numbers
The run in the drawing above found the cause in 11 seconds with 6 read-only tool calls, and the whole incident cost $0.00055 in model fees. You see these numbers for every run you make.
what you build, part by part
Tap or click a number, or a part in the list, to see where it sits. Parts 1 to 5 run on your own laptop; only Parts 6 and 7 go to AWS.
What you leave the course with
your path through the course
Each step below is a real part of the course, with its page count. Parts 1 to 5 run on your own computer, apart from one Part 1 page that reads a real CloudWatch alarm; Part 6 takes the team to AWS, and the last part proves it works.
Every incident is a fault you inject yourself, with a known cause and an automatic check. Tap a note to turn it over. Number 1 is the one in the drawing at the top of this page.
The course is laid out like a book: 70 pages in 7 parts, three opening pages and an optional appendix. Available now: the opening pages and Part 1 and Part 2. New parts are added every week, in book order.
The whole course in one real incident, what you should already know, a one-screen setup checklist, and your model key.

Ive started this course by accident - LLM advised me this site. When I passed few free lessons, I had no doubt - this course should be bought. And I did it with special pleasent price and it was best decision of the month. Content is great, interesting to read and with a lot of practial cases (what makes it different from other souces and books) I hope to teach all the lessons, that will be my supergoal. Glad that I found this resource and speacial Thank You to Roni Das - Great Job!Oleksander, Backend Engineer · System Design Masterclass
The material has been designed with a lot of effort and dedication. It has covered vast range of topic with sufficient content and diagrams wherever required. It complements well with other system design materials.Som · System Design Masterclass
Due to time constraints I am not regularly reading it but whenever I get a chance I read the concepts which have been explained very well. For few topics I felt some more details would be beneficial but I am sure Roni will take care of that because I noticed that the content is getting refreshed and new content is getting added all for free with only one time small fee for lifetime access.Ajay Arora · System Design Masterclass
A written page for every lesson
Every command, real screenshots from real runs on a real machine, diagrams, and notes for Windows.
Code you can download
A zip with every page that has code. What you see run is exactly what you download and run yourself.
Video, being added
Videos for the opening pages and Part 1 are recorded and are being added to the pages. Later parts come as text first, and their videos follow part by part.
What it costs to run
The recorded run cost $0.00055 in model fees. Parts 1 to 5 need no servers. On AWS, from Part 6, a 4-hour lab is about $1.50 to $3 if you tear it down after.
The course is being released part by part, so it sells at an early-access price today. Once every part is released, the price rises to ₹7,777 or $177. If you buy now, you pay once and get every part and every video as it comes out, at no extra cost.

You should be comfortable with Python and the command line, and know the basics of Git; the course does not teach those. You do not need to know AI or DevOps. Part 1 starts from what a language model really does and builds agents from zero, and an optional appendix teaches containers and Kubernetes for anyone who has not used them. The free page "Before you start" has a short self-check and a one-screen setup list.
Both. The course is laid out like a book of parts and pages, and every page is a written lesson with real screenshots from real runs and diagrams. The videos for the opening pages and Part 1 are recorded and are being added to the pages; later parts are published as text first, and their videos follow part by part. Each page with code comes with a zip of that code.
Not yet. The course has 70 pages. Today 26 of them are published, and 3 of those are free to read before you buy; new parts are added each week, in book order. That is why it sells at an early-access price, ₹3,333 in India or $100 elsewhere, which rises to ₹7,777 or $177 once every part is released. Everything published later is included in the one payment, so you get each new part and video at no extra cost.
Very little. Our recorded incident run on 6 November 2026 made 7 model calls and cost $0.00055. Our full test of the first version on 5 November 2026, 220 incident runs on two models, one of them a larger model used only for comparison, cost $2.55 in model fees in total. The page "A cost log for every model call" builds a cost log, so you always see what each run cost.
Only from Part 6, the production part. Parts 1 to 5 need no servers: they run on your own laptop, and you pay only the small model fees. On AWS, a 4-hour lab session costs about $1.50 to $3 if you tear it down afterwards, and about $8 to $9 a day if you leave it running. The first page of Part 6, "AWS from zero, cost safety first", sets up a budget alert and a one-command teardown before anything else.
No. The agent only reads, with read-only tools. When it wants to change something, it proposes one exact change and stops. A person approves it, and then our own plain code, the Executor, applies exactly that change and nothing else. You build this approval flow yourself in Part 3.
In the lab you type both names yourself, as in the recorded run, where the approvers were "student" and "reviewer". The Approval Gate checks that two different names approve and that neither of them is the agent, which is the same rule a team uses at work. In Part 6 you can move the approvals into Slack, where the two names are real people on your team.
A Windows or Mac laptop. Windows works through WSL2, and the free page "Before you start" lists the setup. The full system in the later parts (the demo shop, the cluster and the agent running together) needs about 16 GB of memory; the early parts are lighter. You also need an OpenAI API key, and the page "Getting a model API key and keeping it safe" shows how to create one with a spending limit.
AWS DevOps Agent is a managed product from AWS, generally available since 31 March 2026 and priced at $0.0083 per agent-second. In this course you build your own agent, so you understand every step it takes and can measure it. The page "Buy or build" puts your agent next to AWS DevOps Agent and the agent SDKs, so you can judge when to buy and when to build.
No. AIOps on AWS is its own course with its own price. Buying it gives lifetime access to all of its pages, videos and code, including every part published later.
In India you pay in rupees through Razorpay, by UPI, card or netbanking. Everywhere else you pay in US dollars by card through Razorpay, or with PayPal. The pages unlock on your account as soon as the payment is confirmed.
