What happens when you type google .com into a browser?
First up, you type the website address in the browser’s address bar.
The browser checks its cache first. If there’s a cache miss, it must find the IP address.
DNS lookup begins (think of it as looking up a phone number). The request goes through different DNS servers (root, TLD, and authoritative). Finally, the IP address is retrieved.
Next, your browser initiates a TCP connection like a handshake. For example, in the case of HTTP 1.1, the client and server perform a TCP three-way handshake with SYN, SYN-ACK, and ACK messages.
Once the handshake is successful, the browser makes an HTTP request to the server and the server responds with HTML, CSS, and JS files.
Finally, the browser processes everything. It parses the HTML document and creates DOM and CSSOM trees.
The browser executes the JavaScript and renders the page through various steps (tokenizer, parser, render tree, layout, and painting).
Finally, the webpage appears on your screen.
Over to you: Which other step will you add to the overall process?
A Cheatsheet on Infrastructure as Code Landscape
Scalable infrastructure provisioning provides several benefits related to availability, scalability, repeatability, and cost-effectiveness.
But how do you achieve this?
Provisioning infrastructure using code is the key to scalable infra management.
There are multiple strategies that can help:Containerization is one of the first strategies to make application deployments based on code. Docker is one of the most popular ways to containerize the application.
Next, container orchestration becomes a necessity when dealing with multiple containers in an application. This is where container orchestration tools like Kubernetes become important.
IaC treats infrastructure provisioning and configuration as code, allowing developers to define the application infrastructure in files that can be versioned, tested, and reused. Popular tools such as Terraform, AWS CloudFormation, and Ansible can be used. Ansible is more of a configuration tool.
GitOps leverages a Git workflow combined with CI/CD to automate infrastructure and configuration updates.
Over to you: Have you used Infrastructure as Code for your projects?
Why is Kafka fast?
There are many design decisions that contributed to Kafka’s performance. In this post, we’ll focus on two. We think these two carried the most weight.
The first one is Kafka’s reliance on Sequential I/O.
The second design choice that gives Kafka its performance advantage is its focus on efficiency: zero copy principle.
The diagram below illustrates how the data is transmitted between producer and consumer, and what zero-copy means.
Step 1.1 - 1.3: Producer writes data to the disk
Step 2: Consumer reads data without zero-copy
2.1: The data is loaded from disk to OS cache
2.2 The data is copied from OS cache to Kafka application
2.3 Kafka application copies the data into the socket buffer
2.4 The data is copied from socket buffer to network card
2.5 The network card sends data out to the consumerStep 3: Consumer reads data with zero-copy
3.1: The data is loaded from disk to OS cache
3.2 OS cache directly copies the data to the network card via sendfile() command
3.3 The network card sends data out to the consumer
Zero copy is a shortcut to save multiple data copies between the application context and kernel context.
A Crash Course on Architectural Scalability
Scalability is the ability of a system to handle an increased workload without losing performance.
However, we can also look at scalability in terms of the scaling strategy.
Scalability is the system’s ability to handle an increased workload by repeatedly applying a cost-effective strategy. This means it can be difficult to scale a system beyond a certain point if the scaling strategy is not financially viable.
Three main bottlenecks to scalability are:Centralized components: This can become a single point of failure
High Latency Components: These are components that perform time-consuming operations.
Tight Coupling: Makes the components difficult to scale
Therefore, to build a scalable system, we should follow the principles of statelessness, loose coupling, and asynchronous processing.
Some common techniques for improving scalability are as follows:Load Balancing: Spread requests across multiple servers to prevent a single server from becoming a bottleneck.
Caching: Store the most commonly request information in memory.
Event-Driven Processing: Use an async processing approach to process long-running tasks.
Sharding: Split a large dataset into smaller subsets called shards for horizontal scalability.
Over to you: How do you improve a system’s scalability?

Davos divination: What to expect at this year’s meeting
The Shortlist
Share this email
Curated by Alex Panas, global leader of industries, & Axel Karlsson, global leader of functional practices and growth platforms
Welcome to the latest edition of the CEO Shortlist, a biweekly newsletter of our best ideas for the C-suite. This week, we feature some of the ideas we’re bringing to the World Economic Forum’s Annual Meeting in Davos later this month. Every year, we collaborate with WEF to investigate the year’s most critical issues, and our in-house institutes—covering global business trends, health and wellness, and Black economic development—examine many more. We appreciate the opportunity to connect and hope you find our perspectives novel and insightful. Let us know if you want to meet up at Davos the week after next. You can reach us at Alex_Panas@mckinsey.com and Axel_Karlsson@mckinsey.com. Thank you, as ever.
—Alex and Axel
Global cooperation has flatlined. Our second annual Global Cooperation Barometer finds that, on average, global cooperation has held steady. Precipitous declines in some areas, such as peace and security, have been balanced out by modest increases in foreign direct investment and flows of data and intellectual property.
Economic empowerment made practical. In an update to the McKinsey Global Institute’s pioneering research on economic empowerment, we detail more than 60 ways that businesses can support their workforces, customers, suppliers, and broader communities to build richer, more rewarding lives.
We hope you find these ideas inspiring and helpful. See you in a couple of weeks with more McKinsey ideas for the CEO and others in the C-suite.Share these insights

Asynchronous communication has become an important strategy for modern software systems, particularly in distributed and large-scale applications.
Unlike synchronous communication, where a sender waits for a response before proceeding, asynchronous communication allows processes to continue without waiting. This has a significant impact on the system's performance, scalability, and resilience.
Some real-world scenarios where async communication shines are as follows:
An online store where an order placement triggers real-time calls to inventory, payment, and shipping services. If any of these services experience latency or downtime, the order process stalls, leading to poor user experience and lost revenue. Using a message queue, the order service can immediately enqueue messages for inventory, payment, and shipping.
IoT systems like smart home devices often involve thousands of sensors sending data to central servers. A synchronous approach can overwhelm the server during peak activity, leading to data loss or delayed responses. Message queues allow sensors to send data without waiting for processing.
In a microservices architecture, tightly coupled services communicating synchronously can create cascading failures. With message queues, services communicate indirectly, reducing dependency and allowing independent scaling.
These are just a few examples. There are several potential scenarios where async communication is important. But what makes async communication possible?
This is where message queues come into the picture.
Message queues act as intermediaries, enabling asynchronous between producers (senders) and consumers (receivers). In this article, we’ll look at understanding how message queues work, the various terminologies involved, and the patterns that can be implemented using them.
What is a Message Queue?...
