How To Design For High-TrafficEvents And Prevent Your Website From Crashing How To Design For High-TrafficEvents And Prevent Your Website From Crashing Saad Khan 2025-01-07T14:00:00+00:00 2025-01-07T22:04:48+00:00 This article is sponsored by Cloudways Product launches and sales typically attract large volumes of traffic.
Migrating Critical Traffic At Scale with No Downtime — Part 1 Shyam Gala , Javier Fernandez-Ivern , Anup Rokkam Pratap , Devang Shah Hundreds of millions of customers tune into Netflix every day, expecting an uninterrupted and immersive streaming experience. This approach has a handful of benefits.
We introduce a caching mechanism in the API gateway layer, allowing us to offload processing from singleton leader elected controllers without giving up strict data consistency and guarantees clients observe. With traffic growth, a single leader node handling all request volume started becoming overloaded. it will read version E?
A quick canary test was free of errors and showed lower latency, which is expected given that our standard canary setup routes an equal amount of traffic to both the baseline running on 4xl and the canary on 12xl. We also see much higher L1 cache activity combined with 4x higher count of MACHINE_CLEARS.
The GraphQL shim enabled client engineers to move quickly onto GraphQL, figure out client-side concerns like cache normalization, experiment with different GraphQL clients, and investigate client performance without being blocked by server-side migrations. The Replay Tester tool samples raw traffic streams from Mantis.
Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.
Building on these foundational abstractions, we developed the TimeSeries Abstraction — a versatile and scalable solution designed to efficiently store and query large volumes of temporal event data with low millisecond latencies, all in a cost-effective manner across various use cases. Let’s dive into the various aspects of this abstraction.
Depending on how it is configured, Redis can act like a database, a cache or a message broker. Session Cache: Many websites leverage Redis Strings to create a session cache to speed up their website experience by caching HTML fragments or pages. It’s important to note that Redis is a NoSQL database system. Redis Sets.
And while these events are a great opportunity for us Dynatracers to share our thoughts with our users, it’s also an amazing opportunity to for us to learn from our users about how they use Dynatrace to optimize digital experiences and digital operations in both the public and private sector. Dynatrace news. APAC Series.
In databases like MySQL and PostgreSQL, transaction logs are the source of CDC events. Some of DBLog’s features are: Processes captured log events in-order. Interleaves log with dump events, by taking dumps in chunks. No locks on tables are ever acquired, which prevent impacting write traffic on the source database.
Browsers will cache tools popular among vocal, leading-edge developers. There's plenty of space for caching most popular frameworks. The best available proxy data also suggests that shared caches would have a minimal positive effect on performance. Browsers now understand the classic shared HTTP cache behaviour as a privacy bug.
HashMap<String, SortedMap<Bytes, Bytes>> For complex data models such as structured Records or time-ordered Events, this two-level approach handles hierarchical structures effectively, allowing related data to be retrieved together. This model supports both simple and complex data models, balancing flexibility and efficiency.
They don’t currently have a CDN , yet they do experience high traffic levels from all over the globe: Being geographically close to your audience is the biggest step in the right direction. Interestingly, 304 responses are still a form of redirect: the server is redirecting your visitor back to their HTTP cache.

Explainer flow is event-triggered by an upstream flow, such Model A, B, C flows in the illustration. A hugely important detail that often goes overlooked is event-triggering : it allows a team to integrate their Metaflow flows to surrounding systems upstream (e.g. ETL workflows), as well as downstream (e.g.
Often the data is held in memory by consumers and used as a “total cache”, where it is accessed at runtime by client code and atomically swapped out under the hood. for example Open Connect Appliance cache configuration, supported device type IDs, supported payment method metadata, and A/B test configuration.
the order of the rows on your Netflix home page, issuing content licenses when you click play, finding the Open Connect cache closest to you with the content you requested, and many more). Security Events Platform See open source project such as StreamAlert and Siddhi to get some general ideas.
The service workers enable the offline usage of the PWA by fetching cached data or informing the user about the absence of an Internet connection. When developing a PWA, you can cache the application shell’s resources and assets in the browser. Cached content with IndexedDB. Cache first, then network. Service Workers.
Without build optimizations (incremental builds, caching, we will get to those soon) this will eventually become unmanageable as well — think about going through all images in a website: resizing, deleting, and/or creating new files over and over again. The cache is invalidated on a time basis. Creating an On-Demand builder.
Key Takeaways Redis offers complex data structures and additional features for versatile data handling, while Memcached excels in simplicity with a fast, multi-threaded architecture for basic caching needs. Redis is better suited for complex data models, and Memcached is better suited for high-throughput, string-based caching scenarios.
REDIS for caching. Thanks to PurePath, architects can validate how transactions flow from service-to-service and how traffic gets routed through service mashes (AWS App Mesh, Istio, Linkerd) or proxies. Their technology stack looks like this: Spring Boot-based Microservices. NGINX as an API Gateway. 3 Log Analytics.
Defining high availability In general terms, high availability refers to the continuous operation of a system with little to no interruption to end users in the event of hardware or software failures, power outages, or other disruptions. Load balancers can detect when a component is not responding and put traffic redirection in motion.
Cross Region Read Replicas also enable you to serve read traffic for your global customer base from regions that are nearest to them. Cross Region Read Replicas also make it even easier for our global customers to scale database deployments to meet the performance demands of high-traffic, globally disperse applications.
9GAG is a Hong Kong-based company responsible for 9gag.com , one of the top traffic websites in the world. Beyond running their web properties and applications, Next Digital also uses Amazon RDS (database), Amazon ElastiCache (caching), and Amazon Redshift (data warehousing).
The origin value is an aggregate of the values of all the pages for that origin, computed as a weighted average based on page traffic. This means that an origin that has relatively little traffic, but sufficient to be included in the dataset, is counted equally to a very popular, high-traffic origin. Checking Top Sites.
VPC Endpoints give you the ability to control whether network traffic between your application and DynamoDB traverses the public Internet or stays within your virtual private cloud. percent availability in the event of a server, a rack of servers, or an Availability Zone failure.
What you may be overlooking is that peak-event readiness is about more than just load testing or ensuring that your servers are up throughout a specific timeframe. Additionally, keep in mind that while business stakeholders are likely already aware of these events or promotions, technical teams may not have the same insight.
It increases our visibility and enables us to draw a steady stream of organic (or “free”) traffic to our site. While paid marketing strategies like Google Ads play a part in our approach as well, enhancing our organic traffic remains a major priority. The higher our organic traffic, the more profitable we become as a company.
In particular, he talked about the misattribution potential in a complex microservice architecture where often intermediary results are cached. For example, a ranking team would ingest live user traffic and subject it to a number of ranking configurations and simulate the event outcomes using predictive models running on canary rankers.
The apps are driven using Android’s Application Exerciser Monkey which injects a pseudo-random stream of simulated user input events into the app (a UI fuzzer). Network traffic is also monitored, included all TLS-secured traffic where the developers hadn’t used certificate pinning (i.e., most apps). most apps).
Are caches large enough for this code? Can we do something to optimize giant event loops running bytecode interpreters at the architecture level (perhaps by revisiting ideas from long ago)? They need help tracking down expensive and insidious traffic across the language boundaries (copying and serialization).
These insightful videos will provide you with information from industry insiders that you can use to plan for upcoming events, start conversations, and make an impact in your own organization. Q: How can a business start thinking practically about readiness for peak-load events? Rich Howard on… Peak-load readiness.
When they dug into the data, they found that the reason load times had increased was that they got a lot more traffic from Africa after doing the optimizations. How would you architecture a non-trivial size web project (client, server, databases, caching layer)? What happens when a browser tries to load a website?
A far memory data structure has: far data in far memory, containing the core content of the data structure data caches at clients algorithms for operations. Processor caches can help to hide local accesses too, but not remote accesses. Clients cache the entire tree, but not the hash tables. Refreshable vectors. A worked example.
Data backup and recovery in a DBMS encompass a series of procedures that enable users to generate data backups as a precautionary measure and restore data in the event of data loss, corruption, or system failures. By implementing data abstraction techniques, these challenges can be addressed more effectively.
Redis's microsecond latency has made it a de facto choice for caching. As the use cases for Redis continue to grow, customers have demanded more flexibility in scaling their workloads dynamically, while continuing to be highly available and serving incoming traffic.
MB , that suggests I’ve got around 29 pages in my budget, although probably a few more than that if I’m able to stay on the same sites and leverage browser caching. There’s a trade-off to be made here, as external stylesheets can be cached but inline ones cannot (unless you get clever with JavaScript ). Let’s talk about caching.

For example, a ranking team would ingest live user traffic and subject it to a number of ranking configurations and simulate the event outcomes using predictive models running on canary rankers.
CDN’s Effectiveness: Static Vs Dynamic ContentBack in the day, a CDN’s primary function revolved around caching static content and delivering it efficiently to end-users. Today, 40% of the online traffic is made up of dynamic content, CDN also did their part of the effort to adopt this new reality.
Those events are then retrieved by the Team Service, which stores all allowed requests into an event registry and collapses that request history into the current state of a team upon receipt of a READ request. This approach also minimizes network traffic throughout the architecture, as all external calls are handled by this service.
While this may not seem significant for websites with low traffic, as traffic to the site begins to increase, so does the amount of energy consumed. Without effective caching on the client, the server will see an increase in workload, more CPU usage and ultimately increased latency for the end user. Show me the money!

It is entirely built upon various sets of instruments (also can be called event names) each serving different purposes. Stage – Instrument starting with ‘stage’ provides the execution stage of any query like reading data, sending data, altering table, checking query cache for queries, etc. For example stage/sql/altering table.
